Zenith 12H090
#45

Missing the "Wave Magnet" loop antenna until the electronics return to the cabinet, I hadn't really tested medium wave performance.

A wire attached to the antenna terminal resulted in statons with awful hum. 60Hz pickup was overwhelming the RF stage. Then I remembered I have a ferrite rod in the parts box. This was connected as would be the wave magnet. Lots of stations, and performance peaked up using the old trick of moving the coil on the rod to get the proper inductance. AM sound quality on this set is excellent!

I don't hold with furniture that talks.
