Can't help you out with the issue of your screen name. But, wrt short wave receivers for auto's: I'm aware of both Blaupunkt and Becker car radios with SW and MW in the 50's thru the early 70's (fitted to VW, Porsche, and Mercedes, and even Jag's......to name a few). Some were very good, all were analog. Don't know for sure whether anyone has produced "digital" era radios with the SW/MW capability. But, as popular and useful as those bands are in Europe, I'd be surprised if European manufacturers (like Blaupunkt) haven't continued to offer radios with that capability. Forty or so years ago, they even offered SW converters/adaptors for radios with only the LW broadcast band. If you can't find any SW/MW Blaupunkt or Becker on the web, you might try some German/European car salvage yards or operations. My '72 Volvo P1800 at one time had a Blaupunkt that covered LW/MW/SW, but it was monaural....not stereo. Forty years later......wish I hadn't "upgraded" to digital stereo.
Good luck.... I had a '71 142 E witha Becker Europia radio and the Hirshman SW converter installed in the glove box. More than once I fooled an unsuspecting ham sitting in the back seat into thinking all those bands were in the radio itself.
