In asking the question about use of both a TNC and MMTTY in my previous email, I was acting on two pieces of information.
This is from the MMTTY v1.65 help file: When you begin to set things up, remember that you need to consider how to control PTT while you consider how to generate the AFSK/FSK signal. This is because FSK uses a serial (COM) port, and this must be coordinated with other uses of the serial port. It is not possible to generate FSK and PTT or computer control over the same serial port. If you use FSK and also want to use PTT or computer control, you need two ports. OK, I have two ports. The second information is from an MMTTY pdf, which says to select a port for PTT (only) from Options/Setup/TX--but there is no such port list in the TX tab box in v1.65 of MMTTY. It appears something changed in MMTTY after that pdf was released. Garry, NI6T CU in the California QSO Party (CQP), Oct 7-8, www.cqp.org
