This question is really not an AMSAT one but relates to expertise someone in AMSAT may have. It involves a frequency tracking program such as SATPC does for sats but for an hf application.

We are looking for a program that would: 1. Scan 2-4 frequencies, each on different hf bands on a timed basis - say every 3 minutes.

2. Stop scanning when a connection is requested by a digital mode (pactor or winmor). Resume scanning when a connection is broken.

Note that no rig that we know of provides this scanning capability on a multiband basis.

The application is the WINLINK hub KP2D on St. Thomas, Virgin Islands. The previous set-up involved 3 modems on 3 different bands with separate antennas. It was trashed by lightning. We would like to get it working but with a single rig and modem to avoid the high cost of separate modems for each band and using a multi band antenna.

Does anyone out there know of software that has been developed that would do this or could be modified to do it?

Any help or ideas would be greatly appreciated.
