[MRCA] Fwd: The T-195

[J Mcvey]

 The R-392 has that current gobbling dual pentode output tube . The fulfillment on the thing consumes 15 watts which heats up the radio quite a bit.I replaced that monster with a pair of mosfets. It sounds great and runs much, much cooler.

Dave;


I looked at the AN/GRC-19 to go in the back of my M-37. I wanted to 
combine both amateur radio and military vehicle hobbies. I then got my 
hands on a S-144 telephone switchboard shelter, complete with SB-86 60 
line switchboard. I replaced the switchboard with custom welded brackets 
for a GRC-106a mount. I created a mobile HF station that has 400 watts 
output instead of the 100 w T-195 output. The T-195 seemed to be 
problematic with all the tubes. I only use it on SSB and CW, so don't 
have the RTTY and modem to deal with. It's all period correct and I set 
it up at shows and used it once at Field Day. The set up pic is on my 
QRZ page.

Incidentally I was recently given a R-392. I haven't set it up yet, but 
have some accessories for it. The case was drilled to put on 4 screw 
feet on it. I'd like to get the mounting plate for it after I power it 
up and verify it works correctly
