During the day, the SW'a reception in my shop was awful, just the two local sports-yak stations boom in loud and clear. Even my outdoor wire was not bringing much else in.
I'll try building in a loop for this little guy.

Tonight I'll work on the GE, which uses the 12AU6 as oscillator-converter. Pics coming soon.

To my knowledge, RCA, Motorola and Zenith never made a radio, of this type.
I'm talking about the last 65 years, nothing before that.
The JA5's didn't have much of an AVC circuit. Of course, those were the ones that were sold for under $10.00 USD.
