Motorola B12WA recap and mods

[wa2ise]

Gotta go back in, found the reason I have little sensitivity at the high end of the AM dial, the IF is off. I tuned a station at 710 with this radio, and used a 2nd radio to find this radio's local oscillator. It jams a station at 113. Which means the IF is tuned to 470KHz, should be 455KHz.

Was able to get close to 455KHz by readjusting the IF so I'd jam a station at 1330KHz on the 2nd radio when I tune on the lower side of another station at 880KHz. (peaking the IF after setting up the jamming). After that, I was able to get decent tracking across the AM dial. And decent sensitivity at the upper end of the AM band.
