Which radio? How to avoid analysis paralysis…

I’ve been running the SWLing Post for fourteen years (!!!) and during that time I’d say that one of the top three questions I receive is a variation of “Which radio is better?” followed by a list of radio makes and models.

Sometimes that question is easy to answer because the reader is new to the world of shortwave, they only have two choices, and one is an obvious winner.

In truth, though, that’s very rare.

Most of the time–and I’m speaking from having received hundreds of these questions–I’m asked to choose between a list of radios that the reader has thoroughly researched, uncovering radios DXers and enthusiasts consider to be the best in price class.

They’ve already read numerous reviews, created spreadsheets comparing features/specifications, and they’ve weighed all of the pros and cons by price class.

But they can’t decide.

Analysis paralysis

We’ve all been there, right?

We’re ready to invest a bit of money in a new radio and there are many good options, but there’s no one stand-out…no “perfect” radio with everything we seek.

It’s a slippery slope.  We start our research with some obvious choices. We can’t decide which is best, so we broaden our research, we take deeper and deeper dives, but the more we research, the more confused we become.

Sound familiar? (Trust me: you’re not alone.)

I remember receiving an email once from someone with a list of two dozen sub $150 radios on a multi-tab spreadsheet.They had every feature and specification listed for comparison. They wanted to know which of these radios was “the best.”

I can’t answer this questions for a very good reason.

It’s all about personal preference

My favorite radio from a list of twenty four will likely not be your favorite radio.

Enjoyment of a radio has everything to do with you as the radio’s operator.

Ask yourself, “What’s my main goal–?”:

  • DXing?
  • Weak signal work?
  • Band-scanning?
  • Pirate Radio hunting?
  • Travel?
  • Emergency communications?
  • Casual broadcast listening?
  • Digital mode decoding?
  • Scanning?
  • Mediumwave DXing?

Look at your options with this goal being given the priority.

A rather simple way to avoid analysis paralysis

If you’ve thoroughly researched multiple options, the likelihood is that overall performance between the models is comparable. Sure, some models might have better AGC, better sync, finer tuning, a better encoder, or better sensitivity, etc. but the overall performance package is similar else there’d be no difficult decision to make.

My advice is to pick the radio that you believe you’d enjoy the most.

  • Do you like the display and large encoder on one? Does it look like the sort of radio you could cuddle up to late into a cold winter evening? Go for it!
  • Do you like the compact size and features of one? Does it look like a radio you could pack away for an international flight then use on a mini DXpedition in a foreign country? Grab it!
  • Do you like the comments you’ve read about the robust audio and speaker of a particular model? Pull the trigger!

I’ve been communicating with a reader over the past few days that is stuck in analysis paralysis. No doubt, this is what prompted this post.

Here’s what I told him this morning:

All of the models we’ve discussed are good ones and have overall excellent performance. I would simply pick the one you think you would enjoy using the most.

[Keep in mind that] DXing is a skill.

A skilled DXer can accomplish a lot with almost any radio! It’s easy to fall in the trap of options overload. Just find a good deal on a radio you think you would enjoy and go for it! 

I suppose another way of stating it would be if you believe you’re stuck in analysis paralysis, follow your heart instead of your head.

Matt’s 2022 Portable Loop Antenna Shootout

Many thanks to SWLing Post contributor, Matt Blaze, for the following guest post:


Matt’s 2022 Portable Loop Antenna Shootout

by Matt Blaze, WB2SRI

Followers of this blog may be familiar with my “shortwave radio shootouts” that I post from time to time. The idea is to compare how well different radios demodulate the exact same signal. Basically, I take a bunch of radios, hook them up to the same antenna via an RF distribution amplifier, tune the radios to some distant signal, and record the audio output from them simultaneously. Sometimes that kind of comparison can be more revealing of actual real-world performance than lab measurements or technical specifications.

The other day, I decided to do the same thing, but for antennas instead of radios. Essentially, I inverted the setup. Instead of hooking up different radios to the same antenna, I hooked up identical radios to different portable antennas and recorded them demodulating the same signals at the same time.

In this first of perhaps a series of these antenna shootouts, I wanted to compare three portable amplified magnetic loop antennas. When I say “portable” here, I mean broadband antennas that can pack reasonable compactly for travel and that can be set up and broken down easily for use “on location”, say on a picnic table or hotel balcony, or perhaps installed temporarily on a roof, without too much fuss.

The antennas are:

The Wellbrook FLX1530LN with a 1 meter diameter loop of LMR400 coax. This is my “standard” portable antenna (I use a telescoping broom handle for the support; I wrote about it here as the “signal sweeper” last year). Excellent performance, but on the bulky side for travel. Performs well from LW through HF. Not cheap, at about USD 225 including shipping for the amplifier and power injector, but not including the loop, mounting hardware, or feedline.

The Wellbrook FLX1530LN with a 0.5 meter diameter loop of RG142 (a stiff “aircraft grade” version of RG58 that holds it shape well at this size). I used some 1/2 inch PVC pipe as the vertical support. Because of the smaller diameter loop and thinner coax, it packs down to a much smaller and lighter package than the 1 meter LMR400 version.

The K-180WLA, an inexpensive (about USD 60) 0.5 meter loop from China, sold on eBay and Amazon. The loop is steel wire (which can be wound down to a small diameter for transport), and the kit includes everything you need, including a rechargeable power injector. (However, the power injector uses a noisy voltage booster, so I substituted my own bias-T injector for these experiments). Ostensibly covers LW through VHF, but the low end coverage is, shall we say, somewhat aspirational, as you will see.

– I also recorded, for comparison, the built-in ferrite bar (for LW/MW) and whip antenna (for HF) of the receiver.

This is, of course, only a small sampling of portable loop antennas, both commercial and homebrew. But I wanted to start with what I had on hand and with what meets my own needs. (I omitted from consideration loops that require tuning, since I want to be able to install the antenna without needing access to it every time I change frequency).

For each signal captured, I oriented and positioned each antennas to maximize signal quality, taking care to move them away from each other and interfering metal objects. So you’re hearing (approximately) the best each antenna had to offer (on my roof under suboptimal band conditions).

The receivers I used were four Sangean ATS-909×2 portable LW/MW/SW/FM/Air radios. I believe this to be the best currently available (relatively inexpensive) portable shortwave receiver on the market. It has excellent performance (and is admirably resistant to overload and intermod when used with an active antenna). It lacks a sync mode, but that’s rarely implemented well on portable radios anyway. As a practical matter, it has a good line-level output jack, and I already happened to own four of them.

As in my other shootouts, for each signal, there are a total of five recordings: a monoaural recording of the audio from each of the four antennas, plus a narrated stereo recording comparing a reference (the 1M Wellbrook) on the Left channel with each of the other antennas in succession on the Right channel. The stereo recording is intended as a quick overview, but it will only make sense if you listen in stereo, preferably with good headphones. (You can switch the earcups to get a quick comparison as you listen.)

Jack’s “Perfect Radio Trifecta”

Many thanks to SWLing Post contributor, Jack Kratoville, for the following guest post:


My Perfect Radio Trifecta

by Jack Kratoville

Last Fall, I asked SWLing readers to assist me in my decision as to what portable radio I should take on a two-week trip to Germany. While I came up with an initial list of portables I already own, there were some excellent suggestions on what I might pack. (Sidenote to Thomas – yes, my wife and I packed everything we needed into two carry-on pieces, including my 3 radios. Your expertise continues to serve us well!) To all else, thank you again for your thoughts, suggestions and comments.

The Tecsun PL-310ET was a top choice of many, yet one I had previously never taken into the field. It seemed a logical choice for this trip. The second is the Sangean PL-210 and it just fits in any pocket. The third is a DAB receiver someone had given me, tossed in a drawer, and forgotten about until I realized Germany implemented DAB to replace the MW and LW bands. The only name I can find online is the DAB-8. Being quite small, it made the cut and I shoved it in between a couple of tee shirts.

At our destination, I quickly realized I could not have chosen a better trinity for myself. Here’s why.

Tecsun PL-310ET

If this had been the only radio I brought, I would have been more than satisfied. SW signals abound (the war just two countries away was certainly a factor.) A quick hit of the ETM feature at the top of the hour brought in 40-50 listenable signals, with only a scant few broadcasts religious in nature. Even during the day, I could capture 25 easily. With the bandwidth set at 3 kHz, sound was most impressive. While some were the same broadcast on different frequencies, my only real disappointment was the lack of English-speaking broadcasts – but that was to be expected. The PL-310ET scans relatively fast and holds on to strong signals quite nicely.

We stayed with relatives who lived high on a hill not far from Kiel, in the north of Germany. One push of the ETM feature on FM filled the dial with German voices playing mostly English pop music (the eighties apparently a favorite decade there too.) Simply put, the selectivity on this radio is phenomenal. Odd / even frequencies happily sharing adjacent homes on the dial. And with the pre-emphasis on European FM at 50, the sound from this portable was absolute perfection. As a matter of fact, my first complaint about this radio was a bit of harshness on our over-processed FM commercial stations. In Europe, the audio characteristics of classical, pop, rock and talk stations was simply sweet.

My first night on the AM band was a disappointment. One, maybe two signals that didn’t come in very well. Thankfully, I quickly remembered to flip it to 9kHz and – wow! The BBC, Spanish, Italian, and signals that sounded very much like eastern Europe came booming in. I did not expect all of this and can easily say this was the most fun I’ve had band scanning and DXing in a long, long time! Traveling domestically, I’m more apt to load a memory page, but in this situation, the ETM feature was incredibly useful.

For all DXing, I only used the whip and internal antennas. The battery indicator dropped one notch on the second to the last day we were there. The PL-310ET is an absolute true travel performer.

The Tecsun PL-310ET now sits proudly alongside my CCrane Skywave, Digitech AR1780, Eton Executive Satellit (Grundig edition) and the semi-retired Grundig G5. When we travel to London next year, there’s no question this gets packed again.

Sangean PL-210

A radio that became my constant walking companion during Covid. Hand-sized with a really nice on-board speaker for its size. The sensitivity is impressive and considering its PLL circuitry, has excellent selectivity on FM. AM was also impressive for an antenna no more than a half-inch – if that. It went with me to Hamburg, Berlin, Frankfort and Denmark; always just a quick pull from the pocket for a quick scan. To say I like this radio, well, I own three.

DAB-8

My curiosity in DAB was basically zero. One reader actually PM’d me and offered their own DAB receiver, saying I should check it out. (Thank you, Mike, for that generous offer.) This radio sounds great, but has very poor FM reception. (No MW). It does have inputs for mp3 and Bluetooth, so I figured just in case there was nothing to listen to, I could stream something on it. Its small size was the biggest factor in making the trip. Once settled, a quick daytime scan grabbed nine signals easily on DAB and they sounded great. It was the only band that featured more traditional (even country!) music. It’s back in the drawer at home, but I am very glad it made the trip.

Summary

I truly had a blast listening to the various captures on these three radios, the Tecsun being the most impressive and fun. I’m sure many newer models would be excellent choices, but not once did I wish to have something bigger or better. That doesn’t happen on trips very often, so perfection indeed.

My apologies to those looking / hoping for recordings. I stopped recording from the radio back when I opted to purchase 45rpm records rather than record them, complete with DJ patter on my father’s Webcor reel-to-reel. Once I got into the biz, I recorded enough DJ patter to last a lifetime! Again, thanks to everyone for their input.

The RADDY RF760: Light, Portable, Powerful

(Guest Post)

 By Robert Gulley K4PKM

(Note: This review was requested by Radioddity, who provided the in-production radio to the reviewer, with no strings attached or pre-approval.)

I confess to have been a little bit skeptical when Thomas asked me to review this radio, not because of past experience with RADDY, but because tiny radios in general don’t usually impress me, and I have had plenty of them over the years and considered most of them a novelty. There are a few exceptions, of course, such as the C.Crane Skywave or the Tecsun PL-368, but for the most part there are simply too many limitations to tiny radios for my listening style (this one can literally fit in a shirt pocket!). Upon opening the box I was still skeptical, despite the rather impressive packaging and extras. But hey, a little skepticism is a good thing, right?!

The radio comes with some nice accessories!

Accessories

The radio comes with a thin carry case to protect it from scratches, a rechargeable lithium battery, strap, earbuds and a wire antenna to improve shortwave reception. There is also a Type “C” USB cable for charging the battery. Oh, and a spare set of earbud covers – a nice touch!

Ergonomics

Picking up the radio I noticed right away it has a solid, comfortable feel to the unit. I start with that because most tiny radios feel very flimsy, and usually have something of a rough or hard plastic feel to them. This radio has a glossy feel to it, meaning it is comfortable and actually nice looking. Looks aside, I must admit the ergonomics of the radio impress me. I like the feel of it in my hand, and the controls are laid out well for one-handed operation. Being left-handed, that is not always the case, but the controls seem well thought out for either right- or left-handed folks.

As you can see in the images there are two primary rows of buttons, as well as a tuning knob on the right side of the radio. There is also a belt clip on the back which is unobtrusive – I can’t speak to its longevity as I really never clip a radio to my belt, but for those who do, I suspect it will hold up well with a little care.

The telescopic antenna (fixed) is rather impressive as well, measuring ~18 inches in height when fully extended. As one might imagine, at this length the antenna is fairly fragile – I would not walk around with it fully extended while attached to my belt. For hand-holding it should be just fine, and standing upright on a table it does not tip over, but if out in an open-air environment with a strong breeze it will tip over, so a stand would be advisable.

The display is very readable, and the orange background light which pops on when making adjustments is quite nice. The light stays on for ~9 seconds after pushing any of the buttons. Another nice feature of the radio is a press of any button while the radio is off will turn on the display, indicating time, temperature, and battery strength. Yes, it has a built-in thermometer, and it seems quite accurate, at least on the unit I received.

On top there is an external antenna jack, headphone jack, and slot for the strap.

Operation

For such a small radio it is literally packed with features. I will not go over all of them in this review, but I will cover some of the highlights as well as make mention of most features at least in passing. I was not expecting so many features in this little radio, so I was pleasantly surprised by some of the more advanced options.

Naturally the radio has AM/FM capabilities, as well as weather, air, VHF above the air band, SW and CB (yes, CB!). There is also a customizable frequency range setting for monitoring a desired set of user-selected frequencies. There are presets available for various modes listed in the manual, including predefined amateur radio bands and shortwave stations (always subject to change, of course!).

There is an attenuate function available if needed, as well as numerous step modes for tuning various modes. One interesting feature of the radio is two separate tuning methods, one by up and down buttons, and the other by a tuning knob on the side. These can be set independently of each other in terms of the step-change on a given band. This is particularly useful when scanning a band with the buttons after a station is found, because sometimes being slightly off frequency can produce a better signal – the scroll wheel can be used to make as little as 1 Hz changes.

Finally, there is a very useful bandwidth feature which can change between 3, 2.5, 2, 1.8, 1, and 6 kHz. Tuning is quite functional both with the scroll wheel and the tuning buttons. Holding down the tuning buttons will start a scan of the current band, and a longer press will speed up the scan if no stations are found initially. Unlike some scanning radios, when a signal is found, scanning stops and does not resume. I like that feature better than the alternative method of some radios restarting a scan after 5 seconds or similar. I want time to figure out what I am hearing, and a short stop does not really allow for that most of the time.

This is a very compact and lightweight radio!

Reception

I have to say I am impressed with this little radio. I have listened to amateur frequencies, shortwave frequencies, AM/FM, weather and tried airband (nothing close to me except a minor airfield). I live in a very quiet location in terms of local man-made interference, and this provides a great opportunity to really test out a radio’s sensitivity. My conclusion may surprise you as it did me. This is one sensitive radio, given its small form factor and limited antenna movement. (I did not test the external antenna option. While it has one, I felt it only fair to make tests using the built-in antenna on all the radios I compared it with, thus eliminating extraneous or otherwise hard to compare situations.)

Side by side with one of my favorite portables, the Sangean ATS-909X2, this little guy was right in there with difficult to receive stations. While the Sangean has a much larger speaker and therefore fuller sound, in terms of actual reception, most stations came in about equally. I even used an old, but very reliable Select-A-Tenna to boost AM reception on both radios, assuming the Sangean has a much larger ferrite rod given its size, and yet both performed equally well next to the passive antenna. Impressive!

On various shortwave and amateur stations the RADDY RF760 held its own again, picking up almost station for station what the Sangean and the Sony 7600 GR (another favorite of mine) did, in a package less than 1/3 the size of the Sony, and about ¼ the size of the Sangean. Am I going to dump my Sony and/or my Sangean? Of course not – there are many reasons I prefer those radios for my daily use. But if I were wanting to go extremely lightweight/portable, the RADDY is a keeper with impressive performance and most features one could want in a portable radio, all while still fitting in your shirt pocket. I truly do not know how one could get much better performance or features in another radio this size. It makes one wonder where can they go from here?

FM reception is also quite good, pulling in weaker stations while still being quite listenable. I have heard a few stations on this radio which I have not caught before, and this with some atmospheric noise due to storms in the region. Likewise, listening to AM while there were storms in the general area, still allowed for reasonable reception. As we all know AM broadcasts are highly susceptible to atmospheric noise, especially lightning, but this radio recovered nicely after each static crash. Some radios seem to linger longer in recovery after such events, but this radio was quick to bring back in the signals.

Negatives

In short, there really are not any glaring negatives to this radio, so allow me to point out some little things which are, after all more about personal preference than any deficiency in the radio. Your mileage may vary, as they say.

  • An articulating antenna would be a nice touch, but that might require an increase in size, and likely would make the antenna more susceptible to damage. Many times, being able to bend an antenna this way or that can improve a signal.
  • Changing the frequency steps can be a little fiddly at times, but that’s probably me
  • When powering on, the short press acts like pressing any other button, meaning the light comes on, the time, temp, and battery power indicator displays. A longer press brings up the sleep timer. Two short presses turns on the radio, but not too short of presses. This takes a little getting used to, and I would prefer one longer press to turn on the radio, with the two short presses activating the sleep timer, but that, I know, is getting really nit-picky!

Conclusion

If you are in the market for a small, lightweight, but solid radio – this RF760 is definitely one you should consider. It is so light as to be almost weightless, compact but with easily reachable and useful controls, and has more modes and features than almost any similar radio I have run across. As an old-timer I have to shake my head in amazement at what can be packed into such a small radio these days! This certainly isn’t your grandpa’s transistor radio (and it’s even smaller!). Cheers!

The Icom IC-705: Giuseppe’s pairs his new radio with his homebrew crossloop antenna

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

Dear Thomas,

I wanted to share my new purchase with all SWLing Post friends: the Icom IC-705.

It is truly a great portable QRP transceiver and a great receiver for broadcast listening.

In this video, shot on my balcony at home, is the first listening test on short waves. Crystal clear audio with cathedral effect. My portable cross loop antenna pairs very well with the IC-705.

It’s a simple video but it brings out all the listening potential of this 705.

Greetings to you and all the friends of our community.

73,

Giuseppe Morlè (IZ0GZW)

Thank you for sharing this, Giuseppe! I’ve found that the IC-705 has become one of my favorite portable receivers. It’s truly an amazing radio and, I believe, worth the hefty price tag. 

I published a very favorable review of this radio and 13DKA has as well. Also, check out Giuseppe Fisoni’s comparison of the IC-705 and IC-R8600. The IC-705 is a proper enthusiast-grade radio–I would purchase it just for the receiver functionality. Being a ham radio operator, I also take the IC-705 to the field very regularly–I post many of my field reports on QRPer.com. Recently, we’ve posted a number of articles about protecting the IC-705 during travels and in the field.

Thank you again for sharing this, Giuseppe!

Matt’s 2022 Rooftop Receiver Shootout!

Many thanks to SWLing Post contributor, Matt Blaze, for the following guest post:


2022 rooftop receiver shootout

by Matt Blaze

I realized it’s been long past time for me to do another head-to-head receiver comparison “shootout”, where you can compare the audio from multiple radios receiving the same signal at the same time. Long time readers of Thomas’ blog may remember I’ve posted a few of these before.

So I took advantage of the nice weather and brought a bunch of radios, recording gear, and an antenna up to the roof to listen and record signals under an open sky. My neighbors, no doubt, wondered what I must have been up to. (Don’t tell them I’m just a harmless radio nerd.)

This year, our focus is on eight “dream receivers” from the 1980’s to the present. Each radio is at or near the top of the line in its class at the time of its release. Our radios include, in roughly reverse chronological order:

  • Icom R-8600, a current production “DC to Daylight” (or up to 3 GHz, at least) general coverage communications receiver, with highly regarded shortwave performance.
  • AOR AR-ONE, another DC to Daylight general coverage radio, less well known due to the high price and limited US availability. Excellent performer, but a terrible (menu-driven) user interface for shortwave, in my opinion.
  • Reuter RDR Pocket, a very cute, if virtually impossible to get in the US, small production, high performance SDR-based shortwave portable receiver. It’s got an excellent spectrum display and packs a lot of performance into a surprisingly small package.
  • AOR 7030Plus, an extremely well regarded shortwave receiver from the late 90’s; designed in the UK. It’s got a quirky menu-driven user interface but is a lot of fun to use.
  • Drake R8B, the last of the much-beloved Drake receivers. Probably the chief competitor to the 7030.
  • Drake R7A, an excellent analog communications receiver (but with a digital VFO) from the early 80’s. It still outperforms even many current radios.
  • Sony ICF-6800W, a top of the line “boom box” style consumer receiver from the early 80’s. Great radio, but hard to use on SSB.
  • Panasonic RF-4900, the main competition for the Sony. Boat-anchor form factor, but runs on batteries. Excellent performer, but also hard to use on SSB.

The radios were fed from my portable Wellbrook FLX-1530 antenna, using a Stridsberg Engineering HF distribution amplifier. So every radio was getting pretty close to exactly the same signal at its RF input.

Recordings were taken from the line output, if one was available, or the external speaker/headphone output otherwise. In either case, the audio was then isolated and converted to a balanced signal for recording.

For each signal, I recorded monaural “solo” tracks for each radio, as well as a narrated stereo track in which I compared the audio from each radio (one after the other) against the Icom R8600, with the audio from the R8600 on the left channel and the audio from the other radios on the right channel. This gives you a quick overview of what all the radios sound like.

The stereo recording requires some explanation. For it to make any sense, you MUST listen in stereo, using decent headphones if at all possible. You can switch earpieces back and forth (with your finger on pause and rewind) to get a quick idea of what each radio sounds like compared with a modern receiver, and how they handle things like fades and static.

The solo tracks, on the other hand, consist entirely of the continuous audio from a single radio, with no narration or interruption.

I recorded three different signals, for a three part comparison. (Parts four and up will come, hopefully, soon). I think both the differences and similarities will surprise you.

Part One

Our first signal was the BBC on 9915 KHz, broadcasting from Madagascar to western Africa. This signal was extremely marginal here, intended to show how each receiver can or can’t handle signals down in the noise. It’s definitely not “armchair copy”.

The stereo overview is at:

The individual receiver solo tracks can be found here:

Icom R-8600:

AOR AR-ONE:

Reuter RDR Pocket:

AOR 7030Plus:

Drake R8B:

Drake R7A:

Sony ICF-6800W:

Panasonic RF-4900:

Part Two

Our next signal was the Shannon (Ireland) aviation VOLMET broadcast on 5505 KHz USB. This synthesized voice gives the latest meteorological conditions at airports around Europe. The signal was not strong, but entirely readable. It shows how the radios handle a weak SSB signal. Note that the Sony and Panasonic consumer radios, though equipped with a BFO, were VERY hard to tune properly.

The stereo overview is at:

Receiver solo tracks can be found here:

Icom R-8600:

AOR AR-ONE:

Reuter RDR Pocket:

AOR 7030Plus:

Drake R8B:

Drake R7A:

Sony ICF-6800W:

Panasonic RF-4900:

 

Part Three

Our final signal was a stronger, though occasionally fading, shortwave broadcaster, Radio Romania International on 13650 KHz AM. This gives you a sense of how the receivers performed on a typical “average” signal that you might actually want to enjoy listening to. Because the radios have different filters and other capabilities, I tuned each radio to whatever sounded best; I did not attempt to use comparable settings (since no common settings existed).

The stereo overview can be found at:

And the individual solo tracks are here:

Icom R-8600:

AOR AR-ONE:

Reuter RDR Pocket:

AOR 7030Plus:

Drake R8B:

Drake R7A:

Sony ICF-6800W:

Panasonic RF-4900:

Subsequent comparisons, hopefully soon, will focus on receiver performance on signals in crowded bands and under various kinds of interference and noise.

A quick note on production: The recordings were made with a 12 channel Sound Devices 833 recorder with a Sound Devices SL-16 mixing console. The audio was isolated and converted to balanced output with Switchcraft 318 direct interface boxes (highly recommended for recording radios with pro audio gear).

The stereo track narration was done by me in real time, as the signals were being recorded. I made some comments about which receivers I thought sounded best that were not always the same as what I would later conclude after carefully listening to the solo tracks once back inside. But judge for yourself. I used a Coles “lip” microphone, an amazing ribbon mic designed decades ago for the BBC for use in highly noisy environments. It was very effective in reducing the sometimes considerable street noise and other ambient outdoor sounds.

Thanks for listening and 73!

Paul is impressed with the HanRongDa HRD-747

Many thanks to SWLing Post contributor, Paul Jamet, who writes:

Hello Thomas,

I have just received the HRD-747 I ordered a fortnight ago.

Of course, I quickly made some tests and I’d like to share two of them with you and the regulars of the SWLing Post:

1 – This is a recording made yesterday (23 March 2022) on 12125 kHz; RFA in Tibetan from Tinian Island; the signal is very stable, very clear.

The HRD-747 is sitting in the grass at the foot of a tree in a park! Nearby a pond. Only 6 of the 7 segments of the telescopic antenna are deployed.

My Locator: JN19cc – Locator Tinian Island: QK25TB – 13225 km

Recording:

2 – My second recording is of Radio Tamazuj in Juba Arabic on 15150 kHz 15h45 from Talata Volonondry. This recording was made in the same conditions as the previous one. Again, only 6 of the 7 segments of the telescopic antenna are deployed. The reception is still quite good, isn’t it?

My Locator: JN19cc – Locator Talata-Volonondry: LH31TF – 8526 km

My first SSB tests also allowed me to listen to Russian or Ukrainian radio amateurs in the 20m band. This little device seems to me really very promising.

3- I also made this recording made ton March 27, 2022 in a small park in my city (L’Isle-Adam – Locator: JN19CC) NW of Paris.

It is a ham radio picked up on 14328.80 kHz at 15h30 UTC. No other antenna; only the telescopic antenna of the receiver! 

The HRD-747 has 100 memories per band; this proved insufficient to store all the stations detected during the scan of the entire spectrum from 3.2 to 30 MHz … The scan stopped in the 19 m band!

First impressions? I am impressed by this tiny receiver (only 108 grams with its battery and strap).

I would like to point out that the first version of the manual which was proposed on the site is particularly useful to me. Indeed, most of the keys are multifunction. It’s a habit to get used to, even if everything seems to have been thought out in a very judicious way.

With my best regards. 73’s

Thank you so much for sharing this, Paul. Those results are promising, indeed! The audio sounds quite good in your recordings–especially for such a compact radio.
