[Kenwood] Keying on 30 meters

Thu Jan 25 16:58:19 EST 2007

I'm having a strange problem with 30 meter operation. When I manually key
my TS-940 it operates normally with full power to the antenna. If I try to
send by keying with my computer, the 940 locks up at full power out steady
state. However, if I reduce power by about half it works ok into my
antenna. When I use a dummy load and use computer keying I get normal
operation with full power.
This is a new condition as I have had normal operation in the past and I
have not changed anything in the shack. Any suggestion would be greatly
appreciated.
