Hi Wilfried, The post is already one year old, if you got a solution pls let me know. Couldn't find an email adress from you in qrz.com, so here my reply: To my best knowledge no cat controller like Omnirig, HamLib, Flrig or even CAT in VarAC is able to calculate with a given frequency. But this is needed if the final frequency is produced by a mixer or transverter like with you FT-991A. I run into the same issue with IC-9700 and Kuhne up/downlink equipment. So I wrote a batch for windows, doing the calculation and transfering the result via CAT to the transceiver. An additional batch is doing the SLOT calculation for QSY in CQ Calls, but needs manual input for the slot number. These batches should be easy to adapt to your needs, you will find my email in qrz.com if you like to contact me out of this forum and I could send you those batch files. But they are for windows, not for Linux/pi/Mac! Maybe you could still use the structure. If someone has similar experiences I would like to exchange. 73, Lutz, DH7LK

What you have shown is a part of VarAC.ini, pls check your VarAC_cat_commands.ini where you should find the section [Icom IC-9100] CmdType=HEX PTTOn=FEFE7CE01C0001FD and so on... 73 Lutz, DH7LK

Use 10489.595 where you will find a couple of stations stby. Remember: Slot space is 2550 Hz on Sat. 73, Lutz, DH7LK

Already an old post, but to reduce unneeded traffic on the CI-V Check the following settings (you may include the cat commands): FEFE 94 E0 1A 05 00 75 00 FD CI-V echo back off and FEFE 94 E0 1A 05 00 71 00 FD CI-V transceive off 73, Lutz, DH7LK

Irad has integrated the new cat command format [ENT] - see the latest VarAC_cat_commands.ini Now qsy with TM-D710 works well. TNX
