Thanks for the quick responses guys. I'll try to be succinct.
One click works fine and populates the call sign field perfectly.
Two click does change the frequency as expected but this can be random off frequency received by radio sometimes 1.4kHz sometimes just 500, 600 or 700Hz. The second double click polls the rig and corrects the offset issue with the right frequency.
1. Which CAT connection are you using the USB on the front of the radio or the serial connection to the back.
USB from the rear its a USB A to USB B cable and a good quality one that I use with an RSP so know it to be reliable.
2. Have you tried different connecting cables either to USB or serial on radio?
Tried different USB cables but not front USB. That's an A to A so I'll dig out a cable and try it. I don't have a serial cable, I got rid of those years ago
3. I think your radio is similar to the 7300 and has 2 CAT connections (USB and rear serial) did you set the Yaesu menu to separate the front and rear USB and serial connections, if not please do so.
I don't believe there is a separation possible. The RS232 is already separate. You just choose front or rear for USB/mic/data outputs and inputs. There are options for RPTT select for DAKY, RTS, DTR in the differing mode menus for SSB,AM,FM etc but they all appear to be at defaults and working as expected.
4. Do you also have an amplifier connected to the radio for CAT control?
No Amp connected.
5. What other software is running in conjunction with Log4OM?
Nothing else running normally. I have however tried it with WSJT-X and if I use WSJT-X to select the band, the change is spot on every time. Seems only when commanded via L4OM from the cluster with two clicks it goes wonky.
6. Did you try different settings in the Log4OM program config to the check boxes shown below?
I don't use L4OM to control the rig other than to do SSB frequency changes from the cluster screen. If I do data then that frequency CAT command comes from WSJTX to Omnirig with the log passing into grid tracker then is UDP inbound to log into L4OM. That all works fine too.
The only difference on the snip you sent was my CAT delay was 1 where yours is 0. Changed that too but no difference to off frequency change.
Changed the invert for settings and tested that they work putting USB/LSB 'wrong' for example but the frequency offset still remains along with the flipped sideband.
Not sure now it is Omnirig .ini. If WSJTX uses it the same as L4OM as WSJTX is solid in frequency change each time.
I'm using the 101D .ini file as there is no MP version in Omnirig but they are fundamentally the same rig so it shouldn't be the issue?
I'll let you know if I find anything obvious by experimentation but for now 2 sets of double clicks to change frequency it will be.
