I've told Ray Jay about this portable for years, and apparently I'm not the only one,
https://radiojayallen.com/realistic-dx-440-sangean-ats-803a-am-lw-sw-fm-radio/I still use mine daily, or should I say nightly, as a bedside radio. Radio Jay did knock the selectivity on the FM portion of this portable. In the mid-1990's, I did the Bruce Elving IF TOKO filter swap, from 200kHz to 110kHz, and after that it was, and still is, an FM DX machine. Necessary today with all of those FM translators littered, (And yes, I mean littered.), all over the FM dial. My big gripes are the same as with other portables. When either the memory AA batteries, or the "D" batteries, leaked, that acid would run into the main board. I run my portable off of a transformered wallwart. No battery acid, and no RF hash from a switching power supply. Of coarse, when I loose power at the house, I have to reset the clock and the 9 Memories on it. (B.F.D...) The other pitfall is that ribbon cable that loosely plugs-in to a terminal strip are dissimiliar metals, thus corrosion always seems to happen on the pins of that cable. I've repaired several ATS-803A's / DX-440's by hard soldering those ribbon cable pins to the board. Problem solved, and mine still working +27 years later of having that done. Anyway, +30 years later, my Sangean ATS-803A still rocks on.
