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!

Soviet Era Radio: Dennis reviews the Shoroh R-326 receiver

Many thanks to SWLing Post contributor, Dennis Kalinichenko, who shares the following review:

The Shoroh R-326 military radio

by Dennis Kalinichenko

I believe the piece of Soviet military equipment I recently bought to my collection would be interesting to all readers and contributors.

This is the R-326 “Shoroh” (“Rustle”) general coverage military tube shortwave radio receiver. These were produced decades ago, back in 1963. These portable receivers were in active military use in the Soviet Army until the early 2000s, when the R-326 was finally discontinued . Today, this set is no more a spy secret, but a great collector’s item and also a good receiver for home use.

My set cost me about $150 US, which is rather expensive for this radio. The R-326 was plentiful in the local market in 90-s, right after the fall of the Soviet Union, very cheap and popular between radio amateurs, but nowadays this radio has become more and more rare, so the price rises up.

My R-326 arrived from Khabarovsk city, the Russian Far East, where, I believe, for many years it was on duty in some of the Soviet radio intelligence and defense forces division.
The set includes the radio itself, original military 100 ohm headphones, original rectifier box for 2,5 V output, 12 meter long wire antenna on a reel, the 1,5 meter famous “Kulikov” mini-whip antenna, the isolator for placing it on top of the radio and some minor accessories.

Originally, the R-326 radio came with two batteries–1,25 V each–for field use, but mine are totally drained and need to be serviced, so I haven’t used them so far.

The radio is a light-weight, only 33 lbs, which is a real minimum for Soviet military equipment–the famous R-250 radio’s weight is up to 220 lbs–so, in comparison, this unit is really portable. You can easily put it in your car using the attached leather handle and take it with you on a weekend trip. No other military radio can be so “travel-friendly”; this is one of the reasons it was so popular in the ham radio and SWL communities.

The case is made out of steel and looks so solid you may want to use it as a nutcracker. And you can! In no way could you harm the box constructed to resist nuclear attacks. It is waterproof and sealed–so I can be confident that no previous owner has ever tried to solder something in the guts.

The radio is a super heterodyne containing 19 (!) special mini tubes and covering 6 SW bands, from 1 to 20 MHz. It works in both AM and SSB (CW) modes, having an on-board adjustable bandwidth control from 300 Hz to 6 kHz.

On the front panel, there are two scales: one is rough/coarse, and above is the precise one, a so-called photoscale, which may be adjusted to match real radio-frequency using the four screws near the sun protection visor. With this scale, you don’t actually need a digital readout. It also has a BFO control with a zero setting, adjustable AGC levels for AM and CW, and adjusting screw for matching the antenna input, as marked for 12 m long wire, 1,5 m and 4 m whip.

The radio has no built-in speaker. Instead, there are two output sockets on the front panel, for 100 ohm headphones and 600 ohm line-out.

The power consumption is very low for s tube radio, the rig needs only 1,4 A at 2.5 volts DC (including the lightscale). I use the original power transformer (transistor rectifier) and therefore switch the unit into the 220 AC outlet.

The sensitivity of the radio is extremely high and equals some modern transceivers. The selectivity is also impressive. No doubt it was really great for 1960s. But there’s negative side as well: the radio easily overloads even from the outdoor long wire antennas. The best fit is the “Kulikov” mini-whip that you can see in the photos.

When you switch on the radio, you hear noise, the level of which seems high, so you lower the volume down. Yes, the radio is sensitive and a bit noisy. But thanks to the tubes it sounds really amazing in the headphones. The SSB ham operator’s voice is warm and very clear.
The tuning is very smooth, being actually 2-speed: outer wheel is for fast tuning, inner wheel for precise tune.

It’s absolutely obvious that nowadays a simple Degen or Tecsun may be more useful than this old and heavy unit with big and tough knobs and switches. But what a pleasure sitting in front of this perfect tube radio at night, with the headphones on, turning the huge tuning wheels, looking into the moving dim scale, listening into distant voices and rustles, feeling yourself a Cold War times operator near the rig.

Isn’t this experience priceless?

Indeed the experience is priceless, Dennis! Better yet, your R-326 now has an owner that will keep it in working order and enjoy it on a regular basis. I personally believe keeping these vintage rigs on the air is one way to preserve, and experience first hand, a little of our collective radio history.

Thank you so much for sharing your review and excellent photos of the R-326!

Post readers: If, like Dennis, you have a vintage radio you would like to showcase/review here on the SWLing Post, please consider submitting your story and photos. Being a huge fan of vintage radio, I truly enjoy reading through and publishing your reviews.  I know many other readers feel the same!

The Bonito Boni Whip goes from strength-to-strength: hardcore DXing in compact package

Hi there, subscribers to the Oxford Shortwave Log YouTube channel and regular readers of this excellent website will be aware that I have been using a Bonito Boni whip E-field wideband antenna for a couple of months now. You may have seen my previous post here, detailing some excellent initial DX results achieved with the Boni Whip. What makes this antenna so compelling for a DXer such as myself is simply that it’s so light and compact; I can literally take it anywhere. Currently it lives in a small flight case (see above & below) on the back seat of my car, with either my Sony ICF-SW55 or Eton Satellit, a home-brew battery pack (that literally cost pence) and some peripheral bits and pieces; spare batteries, cables etc. I think it’s probably already clear that if you consider the Boni Whip’s performance as a function of portability and price, it’s out there on its own – I’m not aware of another antenna that can match it. Of course, there are H-field antennas, such as the excellent Wellbrook active loops that will effectively reject QRM, if that’s an issue for the user, but at a significant cost delta.

 

Since my last posting, I have continued to use the Boni Whip regularly on my DXpeditions and upload the reception videos to my YouTube channel. I have been nothing but totally impressed with this antenna, to the point that I’ve actually been surprised by the signals I’ve caught and recorded with it. Recent catches include a number of low-power stations from Brazil, including Radio Bandeirantes – Sao Paolo, Radio Voz Missionaria – Camboriu (on the 49 and 31 metre broadcast bands) and Radio Aparecida. Some of these signals are incredibly difficult to hear in Europe at all, let alone well and yet the ultra-compact Boni-Whip running off AA batteries, coupled to the (equally brilliant) Eton Satellit managed it with aplomb. Other catches include Zambia NBC Radio 1 – Lusaka and a signal from Bangladesh Betar that sounded as if the transmitter was 5 miles down the road!

All-in-all, I’m extremely satisfied with the performance of the Bonito Boni Whip and highly recommend it to those DXers requiring a high-performance, compact antenna, for use at home in electrically quiet environments or on any DXpedition. You certainly won’t be disappointed.

Please find embedded reception videos below and text links that will take you to the Oxford Shortwave Log YouTube channel. Thanks for reading/watching/listening and I wish you all great DX.

Steven is pleased with the Tecsun PL-360 and Anon-Co


Many thanks to SWLing Post contributor, Steven Crawford, who shares the following:

I just wanted to take a moment and thank you for posting my inquiry on the Sony 7600GR. The post comments answered my question.

I also wanted to let you know your confidence in Ebay seller Anna and Anon-co continue to be well founded. Remembering your recommendation and wishing to pick up a Tecsun PL-360 as a spare to my CountyComm GP-5 SSB (Tecsun PL-365), I placed the order for it and a couple of other bits of Tecsun kit with Anon-co.

The order arrived in 6 working days to my Gulf coast Texas home, taking longer to travel from Chicago to my home than it took to move from Anon-co in Hong Kong to Chicago and clear customs.

I then had a question about the connecting cable included with the Tecsun badged, Tecsun / Kato / Grundig / Eaton, AN200 Loop Antenna. Posed through Ebay Anna promptly answered the question and added a photo of the cable to Anon-co’s Ebay listing for the AN200. It just doesn’t get better than that. You can continue to recommend Anon-co with full confidence from my perspective.

I picked up the PL-360 as a lower cost AM/FM/SW backup to the GP-5 SSB that would allow me to accept the risk of using the larger and heavier extended ferrite rod loop stick aftermarket antenna that garnered so much interest on your blog a year ago, before CountyComm warned of accelerated wear on the antenna jack. Happily the antenna works just as well on the PL-360 as it did on the GP-5 SSB.

Overall I am pleased with the PL-360.

The performance on AM and SW appears to match that of the GP-5 SSB (Tecsun PL-365) albeit with a slightly higher noise floor. Whether this is due to something akin to sample to sample variation or a direct result of inherent design differences between the PL-360’s Silicon Labs Si4734 DSP chipset versus the GP-5 SSB’s Silicon Labs Si4735 DSP chipset I can’t say. I can say the PL-360 with the included High Gain loop stick external tee antenna received my list of news gathering AM clear channel stations out to 900 miles during the night hours matching the GP-5 SSB. This list includes WGN, WBBM, WLS and KOA at the furtherest extreme. It also includes Mexico City’s XEEP 20kW at night at 800 or so miles. Switching to SW broadcast using the whip antenna and Tecsun’s / CountyCom EZTune system day or night the PL-360 and GP-5 SSB select and load the same stations within the PL-360’s slightly shorter SW tuning range.

Dittio on FM on the whip. Both radios snag my list of FM stations out to 60 miles.

For my purposes both are extremely close in performance to my Sony SW7600GR when using their supplied external loop stick. On AM if you combine one with the larger and heaver aftermarket loopsticks they will slightly outperform the 7600GR combined with a Tecsun / Kato / Grundig / Eaton, AN200 Loop Antenna. The Sony’s speaker gives it the edge in listening pleasure, but on earphones or plugs all three are close.

None of forgoing addresses the SSB performance as the PL-360’s chipset doesn’t offer that option.

I am pleased with the PL-360, Anna and Anon-co and I do thank you for posting my 7600GR inquiry.

I look forward to your blog.

Steve

Thank you, Steve! I’m happy to hear the 7600GR posting helped you–that’s what this community is all about…helping each other. Thanks to everyone who commented on that post.

And, yes, I think what surprises so many SWLs is the fact that Anna at Anon-Co actually knows Tecsun radios as well, if not better, than the manufacturer. I’ve only had good experiences working with Anon-Co and that’s why I recommend them so readily. Anna provides excellent customer service. (Click here to check out Anon-Co on eBay.)

I’m also happy to hear you’re enjoying the PL-360 and that you understand the risk of using the large ferrite bar on this radio series (PL-360, 365 and GP5 DSP and SSB). I use my antenna as well, though like you, very carefully.

I only use the large ferrite bar when I’m stationary and I’m careful not to put a strain on the antenna in any way; keeping it balanced and steady. In other words, you must handle it with kid gloves. If you take these precautions, I think your radio will enjoy expected longevity.

Thanks, again, Steven for sharing your review! I’m very pleased to hear you’re enjoying the SWLing Post!

The Panasonic RF-B65: the legendary portable with a cult following amongst DXers

Hi there, back in 1990 I was given a Panasonic RF-B40 for my birthday (I think it was my birthday…1990 was a long time ago!). I found that radio to be very sensitive on shortwave, more so perhaps than my Sangean ATS-803A, but ultimately it didn’t really add much value to any serious DXing because it would only tune on shortwave in 5 kHz steps. This rather course tuning arrangement was very limiting in terms of tuning out adjacent noise and copying tropical band – and other signals that weren’t quite on-frequency etc. Frustrated, I  lent my RF-B40 to my brother a few years ago and serves me right; following a house move, he managed to lose it! Quite a shame really because almost three decades later, I would have been very interested to put the RF-B40 through it’s paces on a DXpedition or two. You really don’t see them in action very often at all these days.

 Above: the Panasonic RF-B40 (not mine – unfortunately) and the RF-B60, mid-DXpedition!

At that time, which was around the beginning of the 1990s, I read a review somewhere and it became clear that the better receiver was quite obviously the RF-B65. Upon it’s introduction into the market, the RF-B65 was immediately recognised as an excellent receiver, however, in the intervening years it’s reputation has continued to grow to the point today where it enjoys legendary status amongst DXers and bit of a cult following. There’s a lot of information on the RF-B65 to be found on the internet, so I won’t go into huge detail, but the obvious question is: what makes thsi receiver so special? Well, it’s a quite compact PPL double conversion receiver, covering 153 kHz to 29,999 kHz AM and 87.5 to 108 MHz, FM. It has a keypad for direct frequency input, although you have to press either the ‘FREQ’ or ‘METER’ buttons prior to punching in the numbers to define whether you wish to access a particular frequency, or band. I actually find that slightly annoying, but you easily learn to live with such trivial matters when using a radio of this quality and performance.

Furthermore, there’s an electronic signal strength meter, a DX/local attenuation switch, external antenna jack, SSB reception mode, 1 kHz tuning steps on shortwave (unlike it’s little brother the RF-B40) and fine tuning. The single bandwidth filter is 6 kHz wide and thus limits selectivity a little, although the SSB option and fine tune helps offset that somewhat.  It would have been nice to have a couple more filtering options, particularly narrower for serious DXing in crowded bands, to combat adjacent channel QRM. Build quality is generally excellent as you would have expected from a high-end Panasonic portable and with a very compact form-factor – roughly the size of a paperback book and weighing in at just 1.4 Ibs, it is eminently more portable than a Sony ICF-SW77 or the iconic ICF-2001D/2010.

 

Ultimately, the RF-B65 continues to enjoy an excellent reputation today, nearly 30 years after it was introduced because it is a wonderfully sensitive receiver and arguably the best-ever performing shortwave portable in the paperback book size category – often touted as ‘travel portables’. I managed to acquire an example in as-new condition from eBay, although mind you, I paid through the nose for it lol – that cult following ensures prices remain very robust! I have tested my example against the equally legendary Sony ICF-2001D, still considered by many to be the benchmark for shortwave portables, and in my experience the Panasonic is right up there with it. There’s virtually no difference whatsoever in sensitivity. Where the Panasonic comes a little unstuck is the lack of bandwidth filtering and SYNC, leading to lower selectivity. However, clever use of SSB and fine tuning does provide quite good compensation for these shortcomings. Overall though, given it’s size, sensitivity, build quality and audio, as a complete package, in my opinion, the RF-B65 is equal to the ICF-2001D, and this is why today, it remains so highly sought after.

Below are embedded reception videos and text links to the Oxford Shortwave Log YouTube channel, with various DX catches on the RF-B65. Some of these are considered quite rare in Europe, for example EXPPM Radio Educación’s 1 kW signal from Mexico City, the now defunct ABC Northern Territories on 120 metres and Radio Bandeirantes from Sao Paolo, Brazil, amongst others. Please note; right at the bottom of this post is a link to some very recent comparisons with the brilliant Eton Satellit – one of the very best portables currently on the market today. The vintage Panasonic holds its own, despite 30 years of supposed technical innovation in electronics. Thanks for reading/watching/listening and I wish you all great DX.
