[ARC5] BC sets and others.

[Mike Everette]

The way I heard it, and this may be right, who knows... 262 KHz is capable of greater selectivity, and still-decent tracking, than 455; and with an RF stage, which is typical of most car radios, the image problem is gone.  Though I have amongst my voluminous junque pile a Motorola radio from a 1947 Chrysler, so I was told, that does exhibit images near the top of the dial, hmmm.  This radio uses loctal tubes and with a pair of 7C5s in the output, feeding a 12 inch ex TV speaker, makes some "damgud" audio.  I used it to listen to a couple of stations near the top of the AM band (1520 and 1530 kc I think) that both played "early rock-n-roll" until they both chucked the format about 2004 or 2005.  I still occasionally use it to listen to "Radio Progreso" in Havana on 640 kc, which offers some really good Latin-Caribbean music at night.  Other than that, there is little worth listening to on AM any more.

As for car radios and SW... there were such beasts.  I once ran across a description in one of the Riders manuals of a Buick radio from around 1940 that had something like NINE bands on it.  I bet this was interesting, given the ignition-rich emissions of cars back then.  I'd love to find one of those radios today.

Yes. When I still lived in Missoula, Montana, at least 35 years ago, I would 
go to my favorite junk yard, buy nice-looking auto radios, and build them into 
nice cabinets with an AC supply, and sometimes one of those spider-wound 
flat loop antennas, then sell them. 

The owner of that junk yard, Doug, who was about my age, just loved them. 
He said, and I had to agree, that they were the very best BC radios one 
could buy.

They sure beat the crap out those stupid AA-5s.

I sold a bunch of them. I don't know how many are still around. Probably not 
many/any.

Yes. Those are excellent.

Since my wife just loves to listen to talk radio on AM, I just may build her one.

Or I may just use the NC-109 I have here instead...

She likes to listen to SW too.
