I recently switched to a much shorter USB cable between the rig and my PC (6 Ft long vs 14 Ft log). There never was a problem when using the longer cable, but since switching, I've experienced what others have mentioned on the Facebook group.
The only way to extinguish the indicator, is to keep decreasing the "microphone" setting in Windows 11 till about 70 %. At that point, the indicated volume in VARA-HF is so low that nothing is decoded. My receive bandwidth is 600 Hz, as usual.
No changes have been made to rig settings. The only difference is the shorter cable. All other digital software continues to work as expected (JTDX, FLDIGI/FLRIG, Multi-PSK).

BUSY is NOT determined by VarAC but by the VARA modem.
Closing bug.
