I just upgraded from v2.5 (which worked well) to v2.7.2. I also upgraded Vara HF to v4.5.0. Now when I try to select a frequency, it immediately goes back to zero. Each time I try, the VarAc Log shows "OmniRig: Change Frequency" for each attempt, but nothing changes. The sound card is set properly (Signalink) and when I send a beacon, the rig transmits. Not sure if this is a bug, something with my computer, or something I did wrong. Please help.
Well, it took quite a while, but I finally figured it out and got it working! (Not too bad for a Not very tech savvy guy!) The problem was CAT control - I didn't have it; didn't even understand it. So I had to research, learn the basics, and then apply them. Felt I was on the right track but got stuck when Omnirig Client kept telling me "rig is not responding". Figured the problem may have been with the USB to RS232 serial adapter/cable/driver between the laptop and the rig. Tried one with a PL-2303 chip and then one with an FTDI chip. Neither one worked. As a last resort, I ordered a programming cable designed specifically for the FT-45D (USB to RS232 with FTDI Chip). THAT was the answer. It came in today, and worked perfectly as soon as I set it up! I installed the latest version of VarAc and it had CAT control. Beacon is now going out, and other hams are responding to my beacon. I'm now a happy camper! Thanks for all your help!
