[Kenwood] +AFs-Kenwood+AF0- TS-850 - Goes into transmit mode at power-on

[Bob Farkaly]

I had the same problem with my TS-950. I learned that this was a not 
uncommon problem. The problem turned out
to be the TRX board that controls muting and therefore detects if the trans
is keyed. In the 950, the board is on the control  board located behind the 
front panel.
The number is: X59-3680-00 (TRX)

Good morning all+ACE-



Two weeks after replacing my DC to DC board (info thanks to this group), now
my TS-850 goes directly into transmit at power-on.



I have checked to make sure the Send/Receive button was not pushed in,
disconnected everything but the 12V supply, examined the connector sockets
(externally) for metallic debris that might be keying the rig and have tried
resetting the rig.



A brief search of the internet uncovered one person that found a failed
capacitor leaking across Pin 13 on the 15 pin port located on the back of
the rig.



Before I begin the disassembly process to check out my pin 13, I thought I
might ask the group for advice.



Any help would be greatly appreciated.



Thank you,

Mark
