Trac Keyer
 

I am having some trouble with this keyer locking up my Kenwood TS50S on
transmit when using 40 meter cw. Works ok on all other bands. Have tried
my other antennas and tuners==same thing. Tried dropping voltage from power
supply down to 12 volts. This caused radio to drop out and go to the hello
screen briefly.
If anyone has a schematic/manual for this old outfit, please drop me a line
with ideas or a copy. It is a TRAC cmos electronic keyer model TE122.
It probably needs an output voltage tweak to be compatible with the ts50.
Would like to have a better idea of what to look for before I go digging
around inside it.
Thanks!

Don't know if it's the same Trac keyer I had, or the same problem, but
the one I had didn't work with my TS-450sat until I REVERSED the
keying leads from the keyer to the 450.

Are you saying it does this 'only' on 40 meters. If that is what I read
then you are likely a victim of RFI.

Bypass the leads in/out of keyer with beads, or caps.
