Better men than we have gone quite mad searching for a solution to your 
problem.  One thing I tried was making sure that the microphone's ground 
never came in contact with the power supply's cabinetry.  One would need an 
insulated jack for the microphone input and to see that the output was not 
connected to the cabinet.

I tried many other things, going so far as getting a hand-drawn sheet from 
Ten-Tec service telling me things to try.

Ultimately, conversations with the hams at Ten-Tec convinced me that the 
262G supply's VOX was not designed to operate in an RF environment.  Now if 
I wanted to use VOX, I'd just turn down the drive and solve the problem that 
way.

I have a TT 540 and use a handmike Tentec made and sent me.  When I connect 
the mike thru the power supply my audio is low and ragged.  When I connect 
the mike thru the rear of the radio it works fine and audio reports O.K.  I 
have wired up a D-104 with a heil #5 cartridge and want to use the vox 
feature.  Any ideas on how to get the audio to work properly connecting the 
mike thru the power supply instead of the radio?  Tnx, david W4KA
