Color me "Red"! as in blushing with embarrassment.

I guess I have forgotten my basic troubleshooting skills.

The problem with no PTT was somehow the PTT NPN transistor in my keying 
interface got zapped. Of course, MMTTY stand alone was getting PTT ok, it 
was Writelong, DX4WIN and others not getting the comport PTT as a result of 
the bad NPN transistor.

I replaced it and all is well, although I blew a perfectly good SARTG 
contest.  I have an interface box with PTT, FSK and CW interface to the 
RS-232 comport on my Vista computer.

73 all,
