[TMC] GPE Questions

[telegrapher at att.net]

I notice that (and it's been happening since i got the unit) when i turn 
on the GPE exciter, whether the key is closed or the mic PTT is 
activated, i can hear the carrier or Osc running in the background on my 
receiver.  I actually hear it on any and all of the receivers i have 
tuned to that frequency when they are turned on.  If i were to be 
operating a spilt frequency configuration it wouldn't be a bother but as 
today's operations go, it's noticeable.  Wonder if other operators of 
this piece of gear have the same situation?

Now to determine if it's a buffer tube that is not cut off or excessive 
oscillator rf or just what else.

I know it was worse when i had the VOX hooked to it as a frequency 
source.  As it is now i'm just using Xtal control and the internal 
oscillator.

Suppose this was a hidden problem with the TMC gear and not noticeable 
because of either split frequency or split site operations?

Another item of concern is that they do not specify what kind of level 
to input audio on the back of the unit at the 600 ohm line inputs.  No 
where in the manual does it say.  The only thing that it mentions is 
when tuning the unit, after setting the carrier output to 100 %, adjust 
the audio (mod pot) to see 100% modulation.  But, what would you expect 
the input level to be at that 600 ohm line input point?  It doesn't say 
so i suspect that the engineering order would say what to run there when 
the unit is installed.  And maybe it really doesn't matter?  What level 
of line input audio do you use into a BC transmitter?
