[SBE] Gates FM Solidstatesman TE-3 Exciter

[Dan Mammone]

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
