I was using 2.5.0, under Windows 11. Everything was fine with all three of my radios - IC 9700, FTDX 101, IC 705. Upgraded to 2.5.3. The FTDX 101 works just as before. The IC 705 works as before. But, the IC 9700 does not. When I click on "Test Cat", I get the following error message:
Hamlib error: Invalid parameterIcom_rig_open rig error geting frequency retry=0, err=Invalid parametericom_get usb_echo_off: USB echo off detectedicom c(771): icom_get_usb-echo-off return (1)icom c(771) icom_get_usb echo_off return(1)icom.c(988)icom_rig_open return(1)rig.c(1031:rig_open return(1) while opening connection to rig

The software is decoding normally. I, of course checked everything, USB ports, settings in the radio, etc. Could not find a problem. Tried my Mac, running 2.5.0 (I'm scared to upgrade my Mac to 2.5.3) and it operated the IC 9700 normally.

Need some help!
