What Joe, eluded earlier is actually true in some cases. Software can bombard the serial port with so many commands, without listening to a response and then issue the cat command. The problem there is the radio is processing all the other commands and the PTT is delayed. In wsjt if you are using it alone with the native cat support and a k3, the data rate is very low, not like something like n1mm. There you can use the cat commands for Ptt without any issues. On the other hand, just turning the computer on can toggle the dtr and thus the radio can go into transmit. There it requires disabling advanced parameters in the serial port drivers, to turn off interrogation of ports. 73

Are all those having a similar problem using MicroHam something? or does it occur with other interfaces. 73, Don W3FPR On 11/13/2017 7:00 PM, Bert Garcia N8NN wrote: > The CAT and PTT are on different COM ports, per the installation instructions > for the microKEYER II when using WSTJ-X.
