Sony ICF-2001D/2010 vs ICF-SW77: The final result & next contender ~ The Eton E1

Hi there, after conducting a total of 14 reception tests comparing these two vintage – but excellent portable shortwave radios, there was a clear winner – the ICF-2001D. Interestingly, the second half of the testing identified yet another example of synchronous detection lock dropping out on the ICF-SW77 (during reception of Radio CANDIP, Democratic Republic of the Congo on 5066.4 kHz). Generally, however, and despite a fairly narrow performance margin, the ICF-2001D managed to deliver clearer audio across 5 of the remaining 6 reception tests, giving a final score of 9 to 3 in it’s favour. However, despite the clear win, there is no doubt in my mind at all that the ICF-SW77 is still a great portable receiver and in my humble opinion, remains one of the best ever made.

I believe this comparison test reveals the only likely remaining contender to the top-spot in portable shortwave receivers to be the Eton E1/E1XM. Originally to be marketed as the ‘Satellit 900’ (that never happened) and following a decade of development, involving RL Drake, it was finally introduced in 1995 – and then out of production within a few years. Fortunately, a couple of months ago, I managed to snag one in excellent condition on eBay, for a reasonable price. Now, these radios are not without issues, including, but not limited to; sticky rubber exterior casing, malfunctioning display, failing function keys and general all-round fragility. Not exactly what I would be looking for in a rugged, well-performing portable for my DXpeditions. However, as someone who is always exploring ways to ‘push the performance envelope’ and the obvious potential benefits of passband tuning, an allegedly superior synchronous detection circuit, 4 audio bandwidth filters and tuning resolution down to 10 Hz, the E1 was impossible for me to ignore. Thus, at some point in the near future, I will perform a similar comparison test with the Sony ICF-2001D and the Eton E1. Whichever camp you might be in, I hope you’ll enjoy the reception videos and find the results/conclusions informative.

For now, wishing you all excellent DX.

The Eton E1; possibly the best portable shortwave receiver of all time?

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

sony-test

Hi there, after the first set of recordings were analysed, the score was 4-3 to the ICF-2001D, demonstrating how similar these two great receivers are in overall performance. There were a copule of notable differences however. The synchronous detection circuit on the ICF-2001D allows the user to effectively tune through a signal in 01. kHz steps, whilst the receiver automatically locks onto either the upper or lower sideband, depending on the frequency offset. The ICF-SW77 synchronous detection system differs in that the user must tune the signal and select the sideband. The results of this test confirmed that whilst the ICF-2001D almost always retained SYNC lock, the ICF-SW77 was very prone to losing lock, which of course affected the audio quality in many cases. The other issue was with the ICF-SW77 in that the narrow audio bandwidth filter often seemed to deliver ‘muddy’ audio. Whilst this feature proved to be excellent in terms of mitigating adjacent channel QRM, it also reduced signal clarity/ audio discernibility a little too much in my opinion. However, overall, sensitivity and selectivity was very similar between both radios – in fact, one recording had to be judged a draw (Radio Bandeirantes, Sao Paolo on 9645.4 kHz) – I simply couldn’t split them. Part two of the reception testing follows, using signals from Canda, DR Congo, Brazil, Cuba and Peru.

I hope you enjoy the recordings – text links and embedded videos follow below:

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

sony-test

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:

Myanmar Radio, Yangon, heard in Oxford UK on 49 and 41 metres

Myanmar

Hi there, I thought some of the readers of SWLing post might be interested in my reception of Mayanmar Radio, Yangon, during a late-night DX’pedition in Oxfordshire, UK. I managed to catch them on 5985 and 7200 kHz; the latter was a personal first and perhaps further confirmation that my 200 metre longwire is contributing in a positive way to my mobile listening post. Subscribers and regular visitors to Oxford Shortwave Log on YouTube will know that I am forever trying to push the performance of my vintage portables to the limit of what’s possible, in the hope that I might hear something very exotic. it’s happened once or twice and thus worth all the effort in the small hours. Thanks for watching/ listening.

200m longwire update: rarely heard Radio Tawantinsuyo 6173.9 kHz, Peru, recorded in Oxford, UK

cusco

Hi there, I thought I would share my first reception of Radio Tawantinsuyo, from Cusco, Peru, recorded during the inaugural test of my 200 metre longwire antenna. Of course this  particular reception could be coincidence, but a very welcome catch in any case. Once again, the Sony ICF-2001D performs very well with this large antenna, but as on previous occasions, the rule is always to ‘choose your battles well’ targeting weak DX signals in uncrowded areas of the Tropical Band and elsewhere on shortwave. More details on the longwire antenna to follow in another post. Recorded at the ‘DX woods’ in Oxfordshire, UK on 31/07/16 at 00:27 hrs UTC. Thanks for watching.
