ICOM 2730a > Hamlib -> Gpredict , Can't get it to change frequency based on doppler shifts. But I can manually change the Downlink frequency.

Research direction

The log shows rigctld failing on the IC-2730 at startup: the icom_get_freq call sends command 0x25 and gets back a 0xFA reply, so icom_one_transaction returns -9 in frame.c. Start from that log segment and the icom backend's frequency-set path, then check whether the radio accepts set-frequency commands over COM1 at 19200 baud. Done would mean GPredict's Doppler-corrected frequency reaches the radio through rigctld. This needs radio and Hamlib protocol knowledge, and the thread has been idle for over two years.

Written by the indexing model from the issue text.

Description

I am running a .bat : rigctld -vvvvv -m 3072 -r COM1

It's not working with adjusting the frequency as GPredict makes doppler shift adjustments. If I change the radio control Downlink frequency it gets sent and changes radio, but if I choose to Track then the doppler frequency is not changing on radio.

Can you identify any issue or suggest a better .bat command that may assist in getting the frequency to consistently change with what GPredict is changing the frequency to?

In GPRedict I have Host localhost, Port 4532, Radio type I've tried all choices, PTT Status I've tried all settings, also VFO Up/Down same thing. No matter what I do with settings I can't resolve the issue.
