The brilliant little Tecsun PL-310ET: serious DXing on a budget – part 2

Hi there, here is part two of my original post containing various reception videos for the amazing Tecsun PL-310ET pocket shortwave receiver. I continue to be amazed at the sensitivity and selectivity of this rather modest and diminutive receiver, particularly at it’s price-point of around £40 in the UK and less elsewhere! Here is the second half of the reception videos, with some nice signals from Brazil, Guinea, Ethiopia, Swaziland and India. You might notice that some of these catches involve the use of a 240 metre (approx.) length of barbed wire fence! I’m not sure how beneficial the electrical properties of the fence were, probably somewhere between not great and not good lol, but some pretty decent DX was had with the PL-310ET attached to it via the external antenna socket and a crocodile clip!

The barbed wire fence extends almost to the treeline on the horizon; about 240 metres

I hope you enjoy this set of reception videos, they certainly help to demonstrate the great performance of the PL-310ET and in addition of course, it’s ability to handle large antennas quite well. Embedded videos and text links follow below. Lastly, there are now approaching 1,200 reception videos on my YouTube channel Oxford Shortwave Log and I would like to take this additional opportunity to thank everyone for their support, friendship and advice. In the meantime, I wish you all a very Merry Christmas, a Happy New Year and excellent DX!

Medium wave SDR spectrum with over 20 transatlantic signals: a quick tour

Tour of a medium wave spectrum with over 20 transatlantic signals

Hi there, I thought some of the readers of SWLing Post might be interested in a review of a MW spectrum with multiple transatlantic signals – all with audio. This is one of the recordings I took with the 200 metre Beverage antenna and although I haven’t properly counted, I believe it generated about 50 catches that were either personal firsts or best-ever receptions. You will note that this video is nearly 20 minutes long, whilst the recording is only just over 5 minutes, thus to capture the signals listed below and demonstrate audio to you, it was necessary to effectively ‘rewind’ a few times. I haven’t annotated the video, however, the stations I’ve paused on to demonstrate audio are listed below. There are actually more catches in this spectrum, but hopefully the video will give you a good idea of propagation on the morning of 10/10/16 and the effectiveness of the Beverage/Elad FDM DUO combination. Also note, I didn’t have time to fully optimise the demodulation settings, so for example, I haven’t used AM SYNC in this demonstration. Individual videos of all catches, with optimised settings appear on my YouTube channel Oxford Shortwave Log. I hope you enjoy it! Recorded in Oxford UK on 10/10/16 at 02:00 hrs UTC. Thanks for watching and I wish you all great DX!

Oxford Shortwave Log: transatlantic MW DX catches with 200 metre Beverage – part 1

The brilliant little Tecsun PL-310ET: serious DXing on a budget – part 1

20 Replies

Hi there, a good friend of mine Mr Thomas Brogan mentioned to me recently that his little Tecsun PL-310ET was proving to be an excellent receiver and that it would suit my DXpedition activities. Now, as someone who likes to push the envelope of performance with sophisticated portables, usually coupled to very large antennas, a cheap little Tecsun might not have been an abvious choice for my next purchase. However, Mr Brogan (who has an excellent Youtube channel by the same name – check out his wonderful collection of vintage and modern receivers) previously suggested I buy, for similar reasons, the Sony ICF-SW100. That little masterpiece of electronics turned out to be one of the best receivers I’ve ever owned. I felt compelled to take notice because Tom never gets this stuff wrong! A few days later I found myself in Maplins – again – and there it was on the shelf at just under £40, so I bought one.

I got back into shortwave listening about 18 months ago, after many years of inactivity whilst my poor Sangean ATS-803A rotted away in the garden shed and Sony ICF-7600G long-gone via eBay. To start all over again, I bought a Tecsun PL-360. What a great little portable that turned out to be – there are over 100 reception videos on my YouTube channel demonstrating how it continually performed above and beyond the very modest price tag. I even managed to hear ABC Northern Territories 4835 kHz on it once – simply amazing for a receiver under £30. Given my extensive experience with the PL-360 and having learned the PL-310ET shared the same DSP chip, I was expecting the same, or at least very similar performance and the only real benefit to upgrading to the PL-310ET was the direct frequency access. However, I was wrong about that!

The brilliant Tecsun PL-360 got me back into shortwave radio for less than £30

About a week after buying the PL-310ET, I managed to get out on a DXpedition and with 30 metres of wire attached to it via the external antenna socket, I started tuning around the SW bands. Quite simply, I was amazed at the sensitivity and selectivity of this diminutive little portable. With the proven DSP receiver chip and a number of audio bandwidth filter options from 1 to 6 kHz, coupled with direct frequency access via the keypad, it was a joy to use and listen to. In just over an hour I had copied signals from North Korea, including their internal service KCBS Pyongyang, Zanzibar BC, ABC Northern Territories (at the first attempt!), Zambia NBC Radio 1, Radio Oromiya and Radio Amhara from Ethiopia, amongst others. Brilliant stuff and clearly demonstrating that the overall hardware/software package with the PL-310ET is a step up in performance over the PL-360 and capable of proper DX for a very modest outlay. Interestingly, in a conversation with Thomas Witherspoon regarding the PL-310ET, he reminded me that it was one of his go-to radios for travelling and confirmed it’s excellent performance. I would definitely recommend this radio to novices and experts alike.

Reception videos follow below, with more to come in part 2; I hope you enjoy them. Thanks for watching/listening and I wish you all excellent DX!

Many thanks to SWLing Post contributor, Paul Walker, who shares this recording from his home in Galena, Alaska. Paul notes:

Radio Thailand (13745 kHz) English service to North America at 0000UTC on November 8th, 2016:

Not the strongest I ever hear them, but a good solid clean nearly noise and nearly fade free signal.

That’s an impressive signal, Paul, especially considering the fact that propagation conditions have been somewhat shaky as of late. Thanks for sharing!

Which is the best? Sony ICF-2001D/2010 or ICF-SW77?

11 Replies

Hi there, subscribers to my YouTube channel Oxford Shortwave Log will be aware that I currently operate both of these wonderful vintage portables. I purchased the ICF-2001D only 18 months ago from eBay, based largely on its reputation as one of the best performing portables ever made. Previously I had been using my excellent ICF-SW55 as the mainstay receiver for my numerous DXpeditions, coupled with irregular appearances from my Sangean ATS-803A and the excellent value-for-money Tecsun PL-360. The ICF-2001D proved to be a revelation in terms of sensitivity, selectivity and contrary to popular belief, with careful planning (to avoid crowded bands), is able to cope pretty well with very large antennas. As regards audio bandwidth filtering, SSB and synchronous detection, in my experience, the ICF-2001D is as good as it gets in a portable – or a vintage portable at least. I have lost count of the number of personal-firsts I’ve achieved using this wonderful receiver and as someone who likes to push the envelope a little, I soon started to wonder whether it’s replacement, the ICF-SW77 might prove to be an even better performer. Subsequent online research confirmed there was no absolute consensus on this issue, with followers of these two great receivers firmly placed in both camps.

Sometime later, a good friend of mine, fellow radio hobbyist and subscriber to Oxford Shortwave Log very kindly offered to send me his cherished ICF-SW77 on long-term loan. Like me, he was intrigued to know how it compared to it’s venerable predecessor and thus the deal was done! Upon it’s arrival in July, I started planning a back-to-back series of comparison tests at the very quiet wood in Oxfordshire I used for my DX’peditions, using the same antenna for both recievers – the excellent Wellbrook ALA1530 active loop. In total, I made fourteen reception videos comparing the ICF-2001D and ICF-SW77 and posted them to Oxford Shortwave Log. Both receivers performed very well, delivering excellent reception on the Tropical Band and elsewhere on the shortwave spectrum from Bolivia, Brazil, Guatemala, amongst others. At the halfway stage, I generated a video to summarise the results to-date and this will follow in my next post to swling.com. In the meantime, I hope you enjoy the first half of the reception videos; which follow below:
