Joe, I have often wondered what some of the option offered under Radio Setup in SatPC32 mean. Must admit I have not read the manual as I have not required anything out of the ordinary. Just looking at the Radio Setup there is a RTS+12V selection that may or may not suit your requirements. Erich DK1TB the author of Satpc32 does monitor this site and he will no doubt offer a more positive answer. 73 Colin VK5HI.

Does anyone know if it is possible to output a serial port signal when a satellite is in view.

I would like to switch an external relay circuit when a particular satellite is in view.

Thanks for your explanation Eric, I will explore this further.

Joe, the RTS pins of the Radio 1 and Radio 2 COM ports can be (permanently) set high or low (menu "Rotor Setup"). I added that option several years ago to have a source for feeding CAT interfaces. Also, the RTS pin of the Radio 1 COM port must be set high if the radio is a TS-2000. This became necessary when I replaced (with V. 12.8c) the old MSComm32 component (which supports only 16 port numbers) by a newer one that can handle more ports.

The DTR pins of the Radio 1 and Radio 2 COM ports can also feed interfaces. The Radio 2 DTR pin can alternatively (menu "Options") be used to automatically steer an antenna switch (or cross switch for 2 antennas and 2 radios) when the user switches between uv and vu sats or vice versa. The feature requires different uplink/downlink patterns but doesn't work on the base of a particular satellite name (but see below).

The program's "Priority" feature can be used to automatically switch the program to a particular satellite when it rises. The antenna could then be switched manually (not too much work, I think).

Provided you run 2 radios (to activate the Radio 2 functions) you could theoretically have a group that contains your particular satellite and only others with a reverse uplink/downlink pattern. Then the program could automatically switch to your satellite when it rises and also switch the antennas. (I hope, hi, I didn't test that) . 73s, Erich, DK1TB
