Can you compile Hamlib -- try the latest here...

This may be related to #294 . I am trying to use gpredict for greencube. To define both the uplink and downlink frequencies, I added the following section to ~/.config/Gpredict/trsp/53106.trsp:
[Mode U GMSK FULL DUPLEX]
DOWN_LOW=435310000
UP_LOW=435310000
MODE=FSK AX.100 Mode 5
BAUD=1200
I defined a rig for this as "FT817/857/897 (auto)" with PTT Status set to "Read PTT". Its .rig file is as follows:
[Radio]
Host=localhost
Port=4533
LO=0
LO_UP=0
Type=4
PTT=1
SIGNAL_AOS=false
SIGNAL_LOS=false
My problem is when I start tracking the satellite and click "Engage", at first everything is normal; both the Downlink and Uplink radio frequencies get updated regularly. After about 7-8 seconds, both the Downlink and Uplink radio frequencies get set to the same (Uplink) frequency and my Downlink frequency automatically shifts up. From this point onwards, my Downlink radio frequency tracks the Uplink radio frequency.
Fedora 37, gpredict 2.2.1, hamlib-4.5.4.

Ok -- now run rigctld with "-vvvvv -Z >log.txt 2>&1" added to the line and send me the debug file with a description of what you are seeing.

Unfortunately, the behaviour reported in this bug is still present. I'd appreciate any suggestions from anyone who may have got this working.

Also....try my fork and add "--vfo" to your rigctld command line. VFO mode is much better for gpredict usage. |

@mdblack98 please find the log below. This is with your fork of gpredict, latest snapshot of hamlib and rigctld used with the |

Doesn't look like you were using my fork of gpredict as it is not using the --vfo option correctly. My fork does work with --vfo. |

@mdblack98 I built both from source code. Is there anything that needs setting up in gpredict to make it work? |

Run rigctld with the --vfo option

@mdblack98 this is the 1st line in the output I'd attached previously: Is this what you meant or is it somewhere else I should've added |

That looks correct.
You can redirect the output by adding ">log.txt 2>&1"
Then when things don't work note the time and frequencies involved and send me at least the last few thousand lines of log.txt or zip the whole thing.

Is this what you meant or is it somewhere else I should've added --vfo to?

I found the same problem today. Wanna know how to solve it... |
