You guessed right! The deviation meter panel contains an oscillator injection buffer amp, mixer, 455 IF strip, discriminator, audio amp, and deviation meter.
You can use either the peaking generator or an external signal generator. -------------------------------------------------------------------------- --- In [email protected], "wb6ymh" <[EMAIL PROTECTED]> wrote: I just picked up a S1059B Motorola test set at the swap meet yesterday that has the peaking generator and deviation meter panel options. I'll probably never use it, but I'm curious how the deviation panel is used. There are BNC connectors on it for an antenna and OSC. I'm assuming the peaking generator is jumpered to the deviation panel for use as a local oscillator. Did I guess right, do I get a fish biscuit? 73's Skip WB6YMH
