Kenwood TM-D710 V3.1 This transceiver does not allow to program a VFO between different bands. So you cannot QSY between e.g. 2m and 70cm via a QSY in VarAC as the cat structure of the TM-D710 does not support it. BUT by programming a memory every band is possible. So I changed the section for Kenwood TM-D710 in the VarAC_cat_commands.ini for memory use. Check if you have the latest firmware in your TM-D710. As long as Irad has not changed this section, you can do it with every simple editor. Find attached the new procedure as file VarAC TM-D710 CAT V3_1.pdf If there are any concerns you find my email adress in qrz.com 73 de Lutz, DH7LK

pse show as a copy of your VarAC_frequency_schedule.conf for analysis

I like to recommend to keep it as it is. Some tuners are NOT bypassed during receive, which gives some advantage as working like a preselector. If you would start VarAC without activating the tuner, it could keep the tuner with the last settings, different to the actual band and so the receiver keeps deaf until a bandchange activates the tuner. Even worse if the transmitter will be activated e.g. by the beacon into a untuned tuner. 73, Lutz, DH7LK

HARRIS PRC-138 CAT file Find attached the section for VarAC_cat_commands.ini . Insert it into your VarAC_cat_commands.ini and in Settings, Rig Control and VARA Configurations, select for PTT Configuration CAT AND for Frequency Control CAT "HARRIS PRC-138", your COM port and 9600 Baud, non parity, 8 data bits, 1 stop bit.

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
