I'll keep that in mind. Thanks, Gary!

Thanks, Dan. I did check that. I just checked it again. The exciter pretty much stays on frequency with or without the AFC on, but I'm keeping it on. So it looks like the MO is putting out the correct frequency; it's just not putting out enough power.

Curt,
Take a look at section 5.3 in the manual regarding the carrier frequency issue.

Fellow gearheads:
As a rainy day project, I'm in the process of trying to fix a Gates FM Solidstatesman TE-3 exciter. A while back, it was putting out enough power to keep the transmitter happy, but it wouldn't stay on frequency. After reseating the socketed transistors on the Modulated Oscillator's PCB, it stayed put for a while, but began to drift again. I eliminated the sockets and soldered the transistors directly to the board. Now it stays on frequency.
The problem now is that it only puts out about 3.5 Watts instead of 10 Watts. The only user adjustment on the Power Amplifier is the input drive control, which is pretty much maxxed out. If I remember correctly, it was only putting out 3.5 Watts even before I did the transistor fix, so I'm not entirely convinced that was the cause of this new problem.
If anyone here has experience with this thing, any advice would be greatly appreciated.
Curt
