I love my Sony ICF SW7600GR. I haven't used it much recently, because it is one of the older radios in my collection and there are newer radios that I am trying to get to know. But it is a really great product.
Another Sony radio that I own, the $10 ICF S10MK2, is exceptional. Early this year, I put alkaline batteries in it, and they are still going after more than 300 hours of use. It has surprising audio quality given its low price.
My experience has been that Sony portable radios are built well, sound great, and perform exceptionally.
My SW7600GR frustrates me in one area: mediumwave images within the longwave frequencies. Tuning to a particular frequency in the 150-500 khz range, I may hear a mediumwave station that is actually 910 khz above the tuned frequency. 190 khz and 350 khz are used up by local mediumwave broadcasters, while several other frequencies have fainter mediumwave images.
This radio uses dual conversion for AM reception, so I am not sure why this image problem exists within this frequency range. Is it possible that the longwave frequency range uses single conversion?
The only signal I have picked up near the longwave range is the airport beacon in Montague, California on 404 khz. But the mediumwave images I am hearing dissuade me from investigating longwave further.
