ICOM IC-821H CAT not included

Hello from Switzerland,

Thank you Irad,Team and contributors for the precious jewel you delivered to HAM/EmComm community.

I had success in using VarAC in FM with FT817+SB3002A but not with my IC 821 and Westmountains P&P.

I am using v 8.4.4 and downloaded the last definitions (btw, the 821 still doesn't appear in the menu). I tried various PTT/COM combinations but to no avail.

Any hints welcome.

Hello Irad, I have uploaded the debug file, let me know if it is showing something useful. 73's Adam

Hello Irad, unfortunately the new set of CAT commands to IC-821H does not work. I only have PTT (RTS) working, (that sometimes can't access the USB port but it's OK). More issues I notice are the following: 1. After selecting the varAC icon, the HF modem will always start, no matter if the SAT modem is set to active through Profile menu. This leads to a warning that 2 modems are active from the same folder. OK, I turn off HF modem manually. 2. To test CAT commands to IC-821H through Settings I need a valid VHF frequency to be selected which is not included in the list, I see only HF frequencies. I can only temporarily write something like 144.174000 in that field that I am not certain if it is accepted. In the main program's freq list I did save a VHF frequency. The IC-821H on this installation is making FT-8 on the QO-100 without problems ruling out hardware and PC issues.

Add this to thr VarAC CAt command file and LMK if it works.

Remember that IC-821 has no PTT CAT command so PTT will need to be handled through RTS/DTR .
