My computer's COM 1 port keys the PTT of my PROIII every few seconds when I
first turn the radio on. The PTT in the CW/RTTY interface box described on
AA5AU's web site is connected to COM 1 on my Dell 8300 PC. It happens maybe
every 15 seconds for maybe five seconds. Opening MMTTY will cause the PTT
keying to stop, and it's still OK fine even after I close MMTTY. It doesn't
make any difference which mode the radio is in.
Interestingly, I didn't realized that was happening when I was reconnecting
open wire feeders after turning on the radio after a storm had passed.
Naturally, the radio was either in CW or RTTY set for about 50W output. It
took a couple of transmissions until it dawned on me why my fingers were
getting toasty!
Any ideas to fix it will be appreciated. Thanks.
