[R-390] Still deaf below 8 Mc

[Flowertime01 at wmconnect.com]

Jim,

A TM typo here. The receiver need to be in MGC not Standby.

Standby takes the B+ off a lot of IF plates. VIA the switched B+ line.
You will hear no signals from the receiver in that state.

Set the receiver to MGC and do the test again.
