Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: Radio Aparecida 6135.2 kHz, Brazil

Hi there, another station that's very difficult to hear well in Europe and another demonstration of the exemplary performance of the Sonys and although clearly struggling with this weak signal, an excellent effort by the modestly priced Tecsun PL-310ET which actually produces some audio. Amazing really. Recorded in Oxford UK on 29/12/16 at 20:39 hrs UTC using a Wellbrook ALA1530 active loop antenna.

Tecsun PL-310ET: a quick demo of the excellent audio bandwidth filters

Hi there, here is a quick demonstration of the really excellent audio bandwidth filter options on the modestly priced, but brilliant Tecsun PL-310ET. Whilst out on a DXpedition a couple of weeks ago and using the barbed wire fence as my antenna, I tuned to 590 kHz to check the signal from Voice of Tigray Revolution, Addis Ababa. However, all I could hear was splatter from RRI's huge signal on 5955 kHz. Here is a video with commentary explaining how I was able to copy Voice of Tigray Revolution on this budget portable, despite the horrendous adjacent channel QRM. Quite a remarkable little radio. Thanks for watching.

Radio Hargeysa



I was sent a link to this video about Radio Hargeysa this afternoon - really interesting to see their set-up, inside and out! 73!

Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: Rádio Nacional de Angola 4949.73 kHz

Hi there, this is a really pleasing recording, because a) the PL-310ET managed to pull in a discernible signal from Angola, which in itself is amazing and b) my best ever reception was obtained very temporarily on the ICF-SW55 before it was arguably surpassed a couple of minutes later by the ICF-SW77! Brilliant performance from all three radios and once again, the Tecsun punching above it's weight! Recorded in Oxford UK on 29/12/16 at 19:13 hrs UTC using a Wellbrook ALA1530 active loop antenna. Thanks for watching.


Transatlantic MW DX: CHIN Radio 1540 kHz, Toronto Islands, Ontario, first reception

Hi there, nice to catch another personal first at home, rather than on a DXpedition - it's been a while lol. Here the signal from Toronto is subjected to significant adjacent channel QRM on 1539 kHz, yet the excellent selectivity of the Elad manages to pull out a clear signal. Recorded in Oxford UK on 06/12/16 at 07:48 hrs UTC using a Wellbrook ALA1530 active loop antenna (indoors). Thanks for watching.


Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: Radio Sonder Grense 3320 kHz, Meyerton, SA

Hi there, the next in the series of comparison tests, this time using a stronger signal from Meyerton, but one which was suffering from adjacent channel QRM. You will notice the Sonys cope very well with the noise, but, as might be reasonably expected, even with a narrow filter setting, the Tecsun is far less assured in it's delivery of clear audio. In order to be certain the signal hadn't either faded out or become completely swamped in QRM, the video finally returns to the Sony ICF-SWS77 and once again, Radio Sonder Grense can be heard with reasonable clarity. Recorded at the woods in Oxford UK on 18/12/16 at 19:46 hrs UTC using a 75 metre longwire. Thanks for watching.

Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: Radio Hargeysa 7120 kHz, Somaliland 

Hi there, here is the next comparison test of these three rados and this time using the signal from Radio Hargeysa in Somaliland. This signal can, at times, be sufficiently strong to receive via a telescopic antenna, however, this hasn't been the case for many months. In this particular test, both Sonys manage to deliver discernible audio with relative ease, whilst the Tecsun struggles. Recorded in the 'DX' woods, Oxford UK on 18/12/16 at 18:19 hrs UTC. Thanks for watching.

Sony ICF-SW77: recent DX & comparing performance with the ICF-SW55 & Tecsun PL-310ET



Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: Radio Mali 9635 kHz, Bamako


Hi there, here is the next test comparing the Sony ICF-SW77 against the ICF-SW55 and Tecsun PL-310ET. With this relatively weak signal, both Sony's reproduce stronger and more discernible audio than the Tecsun, however, to be able to hear an exotic station such as Mali on a portable that costs less than £40 is still quite amazing. As regards the Sonys, there's not much in it, although the audio on the ICF-SW77 was clearest with the narrow audio bandwidth filter, whilst the wide setting produced the best audio on the ICF-SW55. Recorded in Oxford UK on 18/12/16 at 17:09 hrs UTC using a 75 metre longwire. Thanks for watching.



Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET: ABC Northern Territories 4835 kHz

Hi there, I mentioned some time ago that I would be testing the Sony ICF-SW77 against the ICF-SW55, having read a review suggesting the original price delta on the SW777 might not be justified, because performance was closely matched with the SW55. I have a lot of experience with the SW55 - it was the mainstay receiver of my Dx'peditions for about a year, until the ICF-2001D took over. The audio bandwidth filters are excellent and of course, it's very sensitve - one of the best ever 'paperback book sized' portables. To mix things up a little and because it's performance has been way beyond my expectations, I threw the PL-310ET into the mix. You would expect it to be nowhere against these two classics, but again, it's relative performance surprised me. Here is a signal from ABC Northern Territories - the first 3-way comparison. Recorded in Oxford UK on 18/12/16 at 17:27 hrs UTC using a 75 metre longwire. Thanks for watching.


Sony ICF-SW77: Zambia NBC Radio 1, 5915 kHz, Lusaka, best ever reception

Hi there, I was in the middle of a multiple radio test involving this receiver, when I copied this really nice signal from Zambia. Easily the best reception I've ever obtained and even nicer to do so with the vintage, but brilliant ICF-SW77. You might remember that it was the runner up in the head-to-head test with it's older 'brother' the ICF-2001D, but nevertheless, still a very capable receiver indeed.....and this reception clearly demonstrates that. Recorded in Oxford UK on 19/12/16 at 18:33 hrs UTC using a 75 metre longwire. Thanks for watching.
