Review of the Gospell GR-216 portable DRM multi-band radio

Many thanks to SWLing Post contributor, Ed, who writes:

Here’s a review on a Swedish Hobby Radio website of the GOSPELL GR-216 MULTI-BAND AM / FM /Shortwave / DRM receiver, which you reported about on 9/6/2016 and is now is reportedly about to go into production:

http://www.hobbyradio.se/en/drm/gospell_en.html

The latest Mediumwave / Shortwave / VHF-FM receiver GR-216 from Gospell can receive both digital and analogue mediumwave and shortwave signals as well as VHF FM broadcasts. The software-defined receiver is based on a NXP chipset. The firmware may easily be updated over the USB connector on the front.

The size of the radio is 240 mm (w) x 120 mm (h) x 150 mm (d) (without the knobs). It is supplied with a 230 VAC power cord, a 230 VAC / 9 VDC power supply and a user’s manual. Its retail price is about xx USD.

The radio has a pleasant design like your favorite kitchen radio but it is also fit for any livingroom. Unlike other products the GR-216 has a soft and clean design and all buttons and controls are easy to operate. It weighs about 2 kg and sits firmly on a table or a shelf. Much of the weight comes from its large loudspeaker (77 mm diameter) and the mains transformer. The two strips on the bottom of the cabinet prevents the GR-216 from slipping around when tuning or pressing the pushbuttons. The AF output power amplifier is 4 W.

There is also a 12 or 24 hour clock and a dual alarm clock (radio or buzzer) and a sleep timer. In addition to the built-in AC/DC power supply there is a DC jack on the rear panel for an external 9 Volt DC power supply if so required.

Continue reading…

Thanks for the tip, Ed! Reading this, it’s most encouraging to see that Gospell reached out to radio enthusiasts and used their input for firmware and hardware upgrades prior to production.

This may be the most encouraging portable DRM receiver yet. Indeed, Paul Walker, has been enjoying his Gospell GR-216 tremendously and–using an external antenna–has captured a number of DRM broadcasts from Pennsylvania. He might produce a review of his own to post here soon.

If anyone else has notes about the Gospell GR-216’s performance, please comment! Could this finally be a DRM portable for the DXer?

Old School (Infrared) Wireless Headphones

by Mario Filippi (N2HUN)

Have you ever mindlessly walked away from your TV with headphones/ear buds still tethered, causing all sorts of havoc? Been there, done that hi hi! Let’s face it; there are plenty of avenues to remedy the situation by upgrading to wireless headphones. Nowadays most state of the art wireless headphones use radio frequencies to achieve a wireless method of listening. For example, my XYL blissfully listens to TV audio with Sony stereo wireless headphones, using a frequency of 915.5 MHz; below is the actual signal viewed with an RTL-SDR dongle.

Sony wireless headphones signal viewed via a SDR dongle; FM modulation.

But hold the presses: there’s good news for folks not averse to old-school technology.

I recently purchased a set of RCA wireless headphones using infrared technology from shopgoodwill.com. Yes, those of us who are somewhat long in the tooth remember infrared as the common method for consumers to “cut the headphone cord” way back when. Infrared is located just above the radio frequency spectrum starting around 300 Gigs (Gigahertz) and is still commonly used in TV and satellite remotes, but less so now with modern wireless headphones operating in the 900 MHz and 2.4 GHz ISM (Industrial, Scientific, Medical) bands.

Admittedly, the new breed of wireless headphones possesses an array of options not available with older infrared units, but if you are satisfied with a no-frills method of headphone freedom (well about 25 feet range that is), check out the pre-owned inventory offered on shopgoodwill.com. The pair I purchased started at $7.99 with no other interested bidders so the total with shipping was $16.82 with the original box and was complete, including the rechargeable NiCad batteries which still functioned but undoubtedly will need replacing. To boot, the money went to a charitable organization.

Wireless IR stereo headphones from shopgoodwill.com

Interestingly, I tried using the wireless IR headphones in conjunction with a shortwave receiver (Panasonic DR22) but there was lots of interference, evidently from the IR transmitter; shortwave and the AM BCB were wiped out by the interference. Now on the FM BCB it worked fine. Even tried it with a scanner and it seemed to work well with FM transmissions (police, fire, EMS) but not with aero AM (108 – 136 MHz).

In the end my venerable older headphones have been relegated to the “shelf of infrequently utilized equipment.” Radio hobbyists might want to visit www.shopgoodwill.com as there are lots more radio memorabilia for window shopping or adding to one’s armamentarium. Remember to read the descriptions carefully as to the working condition. In the interest of full disclosure, I am not associated with ShopGoodWill in any way except that I’m a very satisfied customer. And yes, there are new, state-of-the-art wireless headphones available at a comparable price, so why the reason for this tale? Well, for knowledge, a little history, and a dash of sentimentality, that’s all! hi hi!

Thanks, Mario!

I briefly worked in a RadioShack store in the mid 1990s. We had a set of IR wireless headphones on display and hooked up to a receiver. I remember putting them on and listening to music after/before store hours completing mindless tasks like inventory, clean up, etc. It felt incredibly liberating to walk around the store without a headphone cord umbilical cord! The IR footprint covered the entire store, but fell apart if I had to duck below an end-cap or shelf partition.

Thank you for taking us on a wireless stroll down memory lane, Mario!

Richard’s initial impressions of the Sony XDR-S41D FM/DAB receiver

3 Replies

Many thanks to SWLing Post contributor, Richard Langley, who recently attended a conference in Paris and picked up a Sony XDR-S41D. Richard writes:

The workshop closed around noon on Friday so I spent part of the afternoon walking around the nearby Darty consumer electronics and appliance store.

I wanted to buy a DAB/DAB+ portable receiver just to see what Europe was doing with digital radio. I bought a recently introduced Sony XDR-S41D DAB/DAB+/FM(with RDS) receiver for 79€ (about 11€ off list price).

I can use it in North America to listen to FM and take it with me when I visit Europe for DAB/DAB+ as well as FM.

It has reasonable sound from its 8-cm speaker and pretty good stereo sound on headphones. It has an automatic search mode on both DAB/DAB+ and FM and creates a list of available stations.

In my hotel room in the 13th arrondisement, I could receive 46 DAB+ stations. One of the stations is World Radio Paris (WRP) and they provide English language programming 24 hours per day from BBC World Service, Public Radio International, Radio France International, and Radio Canada International, among others as well as their own programming.

Another available station was Medi 1, which just dropped its shortwave transmissions. I recorded some of the WRP programming:

Audio Clip 1 (MP3)

Audio Clip 2 (MP3)

There is no line output from the receiver but I was able to use the earphone output and crank the volume to maximum to get an acceptable recording level without noticeable distortion.

Happy with my purchase and can’t wait to go back to Europe again, say to England, to try out DAB+ there.

I also spotted three receivers with SW capability on the shelves at the Darty store:

Panasonic RF-3500 for 45€

Brandt BR200D for 45€

Brandt BR120A for 15€

You don’t see SW receivers in North American consumer electronics stores anymore and I’ve not spotted any in airport duty free stores lately either.

I’ve been listening to the XDR-S41D at home and it sounds pretty good on FM, too, and does a good job of displaying the RDS information although a character or two is sometimes cut off the end of the data but that could be the fault of the station. Need to investigate that some more.

By the way, the radio doesn’t come with a case but I found (just before I was going to toss it) that it just fits in the magnetic-clasp case of one of those Air Canada amenities kits that they give you in business class (see photo below).

That’s the second Air Canada item I have recycled. They used to use full-ear headphones with disposable foam covers. They were a perfect fit for the deteriorating covers on my old Sony noise-cancelling headphones. I’ve since upgraded to Bose. 😉

Thank you for sharing your thoughts, Richard! The Sony XDR-S41D sounds like a keeper for sure and is certainly compact enough to easily accompany you on travels to Europe. I was not aware of World Radio Paris either–I see they’re available via TuneIn, so I’ll add them to my WiFi radio station favorites!

A review of CozyPhones sleep headphones

6 Replies

A few months ago, SWLing Post contributor, Mario Filippi–being both a good friend and an (ahem!) enabler–sent the following note:

My XYL bought me a set of CozyPhones for Christmas. If you like listening to the radio, especially at night while in bed, these work great. Speakers are nice and flat. And if you are outdoors you can listen to shortwave and not suffer from ear frostbite hihi.

https://www.cozyphones.com/

[I’ve attached the photo below of] the one I got. Absolutely amazing!

Little did Mario know that, back in 2014, I ordered a pair of similar sleep headphones by the company Acoustic Sheep after reading SWLing Post contributor Anil Raj’s brilliant entry in our Virtual Radio Challenge II.

I purchased an open-box pair of the Acoustic Sheep SleepPhones for about $33 and was very pleased with the purchased…initially, at least.

I used the Acoustic Sheep SleepPhones a couple nights a week for several months. I was disappointed, however, when the braided jacketing started coming off of the headphone cord, bunching up, and the rubberized jacketing underneath began staining my pillowcase, so I was no longer able to wear them at home or when traveling. My wife was amused and said it looked as if I had worn mascara to bed. Well, at least until she attempted to clean the marks off of the pillowcase with limited success.

I feel it’s only fair to state that my SleepPhones were a fairly new product in 2014, thus may have been an early iteration and may not accurately reflect what the product is like currently. I’m guessing that Acoustic Sheep have improved the design and reinforced the jacketing since then, because they seem to enjoy relatively positive reviews on Amazon.

Panasonic Ergo Fit (in-ear) Headphones

At any rate, I set the troublesome SleepPhones aside and and went back to using my go-to in-ear sleep phones: the Panasonic Ergo Fit Headphones. The Panasonics are the least uncomfortable of all of the in-ear headphones and do a decent job of isolating any environmental noises while you sleep. Still, having something inside your ear while you slumber isn’t exactly the definition of comfort.

Enter CozyPhones

I replied to Mario’s email telling him about my experience with the SleepPhones. He encouraged me to give the CozyPhones a try.

I took a quick glance at Amazon (the only distributor I could find for CozyPhones) and the price for a pair was only $22. Almost $16 cheaper than a pair of new SleepPhones? I even noticed combo packs with two sets of CozyPhones for $24. My doubts about quality resurfaced.

I decided to contact CozyPhones customer service directly and ask if their headphones were likely to experience the same problem as my SleepPhones–I mentioned my hesitancy and the fact these would likely be mentioned in a frank review (hint, hint: if quality is poor, this will get a negative review).

They promptly addressed my concerns, standing confidently behind their product, and even offered to send a sample. One week later, the CozyPhones arrived.

The CozyPhones arrived in a thick plastic re-sealable bag (seen above)–a nice touch! Included in the package were both the headphones and a satin carry bag.

Performance

Let’s be frank here: with sleep phones, I’m not expecting the same audio fidelity I would achieve with my Sennheiser HD558s––which, by the way, would be incredibly uncomfortable as sleep headphone; I simply wanted to be able to listen to my bedside radio as I drifted off.

Here’s what I do expect from a pair of sleep headphones:

decent audio fidelity at low volume levels–something suitable for listening to AM or shortwave radio
something with enough sound isolation that it won’t keep my wife awake while I listen to the Voice of Greece into the wee hours
comfort around my head and against my ears as I lie on a pillow…actually, this might be the #1 priority for me
headband’s earphones (speakers) stay in place, don’t shift within the band
quality construction and the potential for product longevity
no black marks on my pillowcase!

Let’s see how the CozyPhones deliver on my points:

Audio fidelity

The CozyPhones easily pass this test. I’m very pleased with audio fidelity for radio listening. Indeed, the audio response is pretty well tailored for AM/SW broadcast listening. FM and music sounds fine, too; good enough that I would consider wearing these in the winter while hiking. Again, these are not audiophile quality to be sure, but they surpass my needs for this application.

Sound isolation

The CozyPhones do a respectable job in this regard. My wife can’t hear what I’m listening to while lying in bed, not even a hint of what I hear. Now, if I were hard of hearing, listening to music and had the volume cranked up, I’m sure she’d at least hear percussive sounds.

Comfort

I should note hear that there are essentially four versions of CozyPhones:

CozyPhones sent me the second version mentioned above, the headphones with Cool Mesh lining and a lightweight Lycra-like exterior. I was quite pleased, as it’s what I would have selected. If anything, I tend to generate a lot of heat, so don’t like products that make me feel even warmer at night while I sleep.

After a few months with the CozyPhones I can say that I’m very pleased with how comfortable they are. The material is soft, the headphone speakers are very thin and seem to stay in place even as I move around and adjust my head on the pillow during the night.

Quality

The SleepPhones I purchased in 2014, in contrast, were also comfortable, but the earphones, essentially mini speakers, tended to migrate within the soft headband. I’d often wake up and find the speakers had completely moved within the band away from my ears; it was then a matter of trying to bunch up the headband material and re-position the speakers.

The CozyPhones don’t seem to have this problem. The ear speakers might shift a little some nights, but not enough to be annoying–certainly not as the SleepPhones initially did.

The braided headphones cord is non-obtrusive and comes out the back of the headphones. So far, the CozyPhones haven’t suffered the same fate as the SleepPhones–the braid has remained intact and seems quite sturdy, resilient to light tugging and normal movement.

And as for my pillowcase? Still clean…no black marks.

Summary

If, like me, you enjoy listening to radio in bed, but don’t want to disturb your partner, CozyPhones really are a fantastic option.

Perhaps as a side effect of my years of SW listening, I find I’m a bit sensitive to environmental noises when I travel; often hallway noises, nearby traffic, children screaming, doors slamming, can disturb me, so I never leave home without earphones in my pack to quiet the noise. Quite often I’ll listen to my radio at bedtime, then, right before nodding off, I tune to a blank spot on the AM dial to the soothing sound of static. This “white noise” tends to drown out other abrupt environmental noises, and I find I drift off peacefully.

I think CozyPhones will serve you well. At $18-22 shipped? I think they’re a good bargain and a great gift. In fact, I intend to buy a pair for my wife! Shhhh…don’t tell her.

Brilliant hard-core DX with the USB-powered Bonito MegActive MA305 antenna

5 Replies

Hi there, you might remember my post from last month focussing on the Bonito MegActive MA305 E-field antenna, kindly supplied to me for testing, by Bonito themselves. That post was essentially a report on my experiences travelling to Crete with the MA305, navigating through security at London Gatwick and Heraklion airports (mostly with relative ease), but more importantly, how well it worked with the equally excellent Eton Satellit portable receiver. Whilst in Crete I managed to copy a number of personal firsts, including CRI on 7295 kHz, via their relay in Bamako, Mali, The Voice of Beibu Radio on 5050 kHz, Nanning, XSL ‘Slot Machine’ on 6251 kHz USB, Ichihara, Japan, S32 ‘The Squeaky Wheel’ on 3828 kHz and NHK World Radio Japan, 11910 kHz. I also copied RTM Wai/Limbang FM on 11665 kHz from Kajang, Myanmar Radio on 5985 kHz and AIR Bhopal on 4810 kHz, amongst others – all of which I would certainly consider to be difficult catches in Europe.

The USB-powered MegActive MA305 is perfect for DXing on the move…

Despite excellent all-round results from the ultra-portable USB powered MA305, there was one signal I copied, which more than any other, demonstrated the DXing credentials of this antenna; Radio Tarma from Peru on 4775 kHz. With a TX power of 1 kW, this is a very difficult station to hear in Western Europe, even with a longwire. To catch this station in Crete, with a 22 cm antenna was incredible and it was at that point during my trip that I realised E-field antennas really can work superbly well for hard-core DXers on the move.

Upon my return to Oxford, I immediately started thinking about a DXpedition to the local woods I use for what I consider serious DXing. For obvious reasons, E-field antennas require an electrically quiet environment to ensure maximum SNR performance. In noisy environments, these types of antennas amplify the signal of interest and the background ‘electro-smog’, thus increasing signal levels but critically, not signal-to-noise. Fortunately, the Oxfordshire wood I have been using for a couple of years is only a 10 minute drive from my QTH as I sort of live in the countryside anyway and the QRM levels there are just about zero. Now, given that this was essentially an experiment to determine the best possible performance from the MA305, I decided to use my best portable radio. It was quite tempting to pack up the Elad FDM DUO which running on a home-brew battery pack has proven itself to be my best (pseudo) portable radio. However, this is supposed to be a real-world test and in this type of scenario, DXpeditions with the Bonito antenna are much more likely to be undertaken with a portable radio. For these reasons I decided to conduct the test with the venerable Sony ICF-2001D. Having proven to be a superb receiver over many, many dxpeditions (check out the evidence on my YouTube Channel Oxford Shortwave Log) and still regarded by DXers as one of the best ever portable radios – possibly the best – it was the obvious choice.

My portable DXing kit comprising the Bonito MegActive MA305 antenna and the Sony ICF-2001D…a bit of a legend in DXing circles…

I ventured out in early June around 23:00 hrs BST (22:00 hrs UTC), parked the car on the edge of the wood and proceeded to set up my cheap camera tripod, slightly modified to accept a 2 metre-long stainless steel tube, into which a slightly thinner 1 metre tube was mounted, topped off with my partially disassembled ‘Selfie Stick’ – which made it back from Crete lol. The antenna was set up in less than 5 minutes and approximately 4 metres above the ground – much quicker and easier than de-spooling 100 metres of wire! With fresh batteries in the Sony and the MA305 powered up using the USB power brick supplied by Bonito, I was ready to start listening. Almost immediately I heard and recorded a personal first; Lao National Radio, Laos, signing on 6130 kHz, with an excellent signal. Hearing them in the UK was only made possible by the annual two week shut down of the PBS Xizang transmitter in Lhasa, Tibet, but hey, I’ll take it. A brilliant start to my listening session.

Over the next two hours I was amazed at what could be heard using this 22 cm amplified antenna. Bearing in mind I have spent many hours at the woods previously, listening via various 100 metre longwires and a 200 metre Beverage, my expectations were, I thought, realistic in that the MA305 coupled to the Sony would catch some very good DX. However, I did believe there might be an absence of at least some of the more exotic low power stations on the Tropical Band – afterall the MA305 is a very short antenna. Clearly I was wrong, because what transpired during the session surpassed anything I thought possible with this set-up. A list of reception videos follows below and further below, a selection of embedded videos. Some of the entries on this list simply stunned me at the time. Rádio Educação Rural for starters is such an incredibly difficult signal to hear in Europe, even with a very large antenna. Thus, to hear them on an ultra-compact set-up felt very special. Radio Mali is another station that is very difficult to catch with any modulation, except on a large antenna and yet there they were – at the first time of trying. Similarly, Rádio Nacional de Angola and Alcaravan Radio are exotics that at best deliver very weak audio – and most of the time no audio. Furthermore, the signals from Emisoras Pio XII, Myanmar Radio and Rádio Clube do Pará were verging on what I would call superb…I’d never heard anything like it previously except via 100 (or more) metres of wire.

The ICF-2001D and MegActive MA305 Rádio Educação Rural transmitter site in Tefé, Brazil

So what’s next? Well it would certainly be an interesting experiment to compare the performance of the MegActive antenna with the Wellbrook ALA1530 active loop in a similar environment. I have used the Wellbrook on DXpeditions several times, with often excellent results, however, it’s not designed to be portable and if SNR performance could be demonstrated as similar between these two products, given a very favourable price delta, the Bonito antenna would add up to be a very compelling purchase decision. More on that to come. In the meantime, thank you very much for reading/watching/listening and I wish you all excellent DX.

Travelling and DXing with the Bonito MegActive MA305 antenna

21 Replies

Ok, so officially it wasn’t a DXpedition; it was a well needed vacation in the sun after several hectic months of work, some of which involved travel to slightly more exotic locations. However, these days, I view any travel, whether it be for business or pleasure as a ‘DXpedition’ opportunity! Some of you might remember that I purchased a Bonito Boni Whip at the beginning of 2017 because (a) I needed another antenna and (b) a second Wellbrook loop felt like too much of an extravagance. They’re excellent antennas for sure, but at around £300, I couldn’t justify buying another. Thus, for about a third of the price I bought the Boni Whip. It proved to be an excellent choice – very compact and so perfect for my regular DXpeditions, quick to set up and capable of really excellent DX. There are many videos on the Oxford Shortwave Log YouTube channel that are testament to this. I wrote a couple of articles, published here on the SWLing Post which were seen by Dennis Walter of Bonito, who subsequently contacted me and offered to send over their MegActive MA305 E-field antenna for testing. Dennis made it crystal-clear that I was to ‘do my own thing’…test the antenna in any way I saw fit and publish my findings so DXers/radio enthusiasts could learn more about the capabilities of the antenna – from another DXer. I was happy to agree to this arrangement and the MegActive MA305 duly arrived, complete with two lengths of (bayonet BNC terminated) high quality H-155 coaxial cable.

My portable Dxing kit with MA305 antenna The MA305 power inserter and USB power ‘brick’

The specifications of the MegActive MA305 are very similar to the Boni Whip; they both offer a Gain of +3 dBs, second and third order intercept points of greater than +30 and +50 dB respectively and both tune to 300 MHz. The MA305 is supplied with a longer radiating element and tunes down to 9 KHz (versus the 20 kHz lower limit for the Boni Whip). Obviously this isn’t a specification that is going to concern most radio enthusiasts; both offer fantastically wide operating bandwidths. The way in which these antennas do differ quite significantly however, is in how they are powered. The Boni Whip operates from 12 to 15 V, whilst the MA305 operates from 5 to 15 V. Bonito’s design philosophy regarding this feature is based on the increasing difficulty in procuring reasonably priced analogue external plug-in power supplies (they are no longer allowed to be produced due to power consumption restrictions).

Interestingly, when the power supply for my Wellbrook ALA1530 packed up, I called them to purchase a replacement and was told they only have limited stocks remaining. Thus, a solution for powering active antennas with a suitable low-noise supply is an issue that needs resolving. The guys at Bonito figured a USB power source was suitably quiet and with USB ‘power bricks’ almost ubiquitous these days for charging mobile phones and other portable electronic devices on-the-go, the idea could be applied to their active antennas. The result is the MegActive MA305, designed to operate at 5 Volts with no loss of performance. As a DXer who probably spends more time listening on DXpeditions than I do in my shack at home, the USB power solution was perfect. I myself often carry a cheap Chromebook laptop to use as an additional power source for my camera phone when I’m DXing, so Bonito’s design approach resonated with me completely.

Travelling with the MegActive MA305

Ok, so the MA305 is very compact and very light indeed – perfect for a trip to Crete! However, I know from many conversations with my YouTube friends and followers that some of us feel a slight sense of trepidation carrying shortwave radios and antenna systems on board flights, be they national or international. I myself wasn’t really concerned other than if my bag got pulled from the X-ray machine, there’s often quite a long wait whilst the security staff work through the queue of luggage requiring er…human intervention! Predictably, my rucksack did get pulled and I waited patiently until it was my turn to explain the contents! Looking back on this retrospectively, it’s hardly surprising. Other than the usual holiday paraphernalia, my rucksack contained:

A 10.0 metre length of H-155 coaxial cable
A 1.0 metre length of H-155 coaxial cable
Eton Satellit receiver
MA305 Coaxial Power Inserter
MA305 Antenna Amplifier
Bonito USB ‘Power Brick’
Bonito USB Power Cable
NooElec RTL-SDR dongle
NooElect ‘Ham It Up’ upconverter
Various screened cables and connectors
10 metres of equipment wire

I explained to the (friendly) security chap that I was a shortwave radio hobbyist and identified the various pieces of equipment for him, as he removed them from my rucksack. He confirmed my X-ray had ‘lit up’ (in blue as it happens) with metallic/electronic items and was even kind enough to swivel his monitor to show me the mess of items strewn across the screen – just as I had thrown them all into my rucksack! However, after quickly swabbing some of the items, he said all was fine and hoped that I enjoyed my holiday and listening. Service with a smile at Gatwick Airport – and I was on my way. My outbound experience got me thinking whether it would be possible to pack my DXing kit in such a way that it wouldn’t alarm airport security. Thus, for the trip home, I packed all of my cables into my (checked-in) suitcase. I figured it would be obvious there was no security risk associated with cables alone. I then packed my RTL-SDR, upconverter and all of the MS305 components very neatly into a single box and put that in my carry-on rucksack. Now, some might argue that security measures at Heraklion International Airport in Crete differ a little from London Gatwick, but I observed staff at the X-ray machine very carefully monitoring every piece of luggage passing through it – including my own and I passed straight through without a problem. All I did was take my laptop out as usual, and put it in a separate tray. Job done.

DXing with the MegActive MA305

My listening post in Crete, with the brilliant Eton Satellit receiver

My apartment in Crete was on the second floor and a large balcony provided a decent outdoor location for DXing. As regards electrical noise, the location was much quieter than my shack at home, but it certainly wasn’t perfect, thus a good test of the MA305 in a real-world pseudo-urban environment. in an attempt to improve SNR, I bought a cheap ‘Selfie Stick’ and some tape and managed to construct a mount for the amplifier, increasing the overall height above ground by about 1.5 metres and displacing the radiating element an additional 2 metres thereabouts from the building. I’m not sure whether it made much difference, but it seemed like the sensible thing to do for less than 10 Euros.

During my week-long stay, I managed to fit in several listening sessions and copied some really excellent DX from this ultra-compact, USB-powered set up. In fact, the MA305 coupled to the Eton Satellit performed so well, I managed to copy a number of personal firsts, including CRI on 7295 kHz, via their relay in Bamako, Mali, The Voice of Beibu Radio on 5050 kHz, Nanning, XSL ‘Slot Machine’ on 6251 kHz USB, Ichihara, Japan, S32 ‘The Squeaky Wheel’ on 3828 kHz and NHK World Radio Japan, 11910 kHz. I also copied RTM Wai/Limbang FM on 11665 kHz from Kajang, Myanmar Radio on 5985 kHz and AIR Bhopal on 4810 kHz, amongst others – all of which I would certainly consider to be difficult catches in Europe. To hear them with an 18 cm antenna felt pretty special. African shortwave stations were also very well represented and I managed to copy a number of them including Radio Hargeysa on 7120 kHz, Voice of Tigray Revolution on 59150 kHz, Radio Oromiya on 6030 kHz, Radio Fana on 6110 kHz, Radio Ethiopia on 7235 kHz, Radio Sonder Grense on 3320 kHz and Radio Guinée on 9650 kHz. I expected to hear all of these stations, except for Radio Guinée, which is farther away from Crete than the UK. So, all-in-all an excellent result.

Despite hearing a lot of excellent DX whilst in Crete, there is one signal I copied, which more than any other, demonstrates the DXing credentials of the MA305 – and Eton Satellit for that matter. In the early hours of the morning (00:59 hrs UTC) I copied and recorded Radio Tarma from Peru on 4775 kHz. With a TX power of 1 kW, this is a very difficult station to hear in Western Europe, even with a longwire. To catch this station in Crete, at all, was incredible on an ultra-compact set-up. It was at this point during the trip that I realised E-field antennas really do work superbly well for hard-core DXers on the move. It inspired me to conduct further tests back home in the Oxfordshire countryside, where electrical noise is absent. This I did a few days ago, with some quite amazing results on the Tropical Band. More on that to come in my next post. In the meantime, please find text links and embedded videos for selected reception recordings, below. Many more recordings are available on the Oxford Shortwave Log YouTube channel and please don’t hesitate to contact me if you require further information on the MA305 or the Eton Satellit. Thanks for reading/watching/listening and I wish you all excellent DX.

Many thanks, Tom, for sharing your review!

Funny story…

After watching most of Tom’s video this morning while packing for YAT (Yet Another Trip–!) I thought purchasing a V-115 from Amazon might make a lot of sense. Frankly, it would be handy to have a portable that does even a mediocre job of recording shortwave to MP3 files.

I did a quick search on Amazon only to discover, in the search results, that the quickest I could receive the V-115 was next Wednesday. I considered shipping it to my hotel.

Once I opened the product link for the V-115, I saw the following message from Amazon:

I thought, “What?!? I don’t remember this purchase…!”

A bit confused, I opened the large container that holds all of the portables I use for review benchmarks. It was the only place this radio could be hiding. Inside, I discovered an unopened box containing an Audiomax SRW-710S–looking in my Amazon order history, I confirmed that the Tivdio V-115 is also badged as the Audiomax 710-S and Amazon linked the two.

Then, my memory kicked in! I purchased the SRW-710S for review, but pushed it to the backburner. Then in December 2016, SWLing Post contributor, Troy Riedel, submitted a full review of the SRW-710S.

After Troy’s review, I sat the 710S aside and, frankly, forgot I had even purchased it (after all, quite a few radios come into and go out of my shack!).

I’ll pack the 710S and test its recording capabilities on the road this week.

Tom seems to have been favorably impressed with the Tivdio V-115–perhaps the Tivdio version has had some performance tweaks?

Post readers: Anyone else have a version of this radio? What are your impressions? Please comment!
