When using WSJTX to operate FT8 on 40, 80 and 160 meter, I have no issues. When I try to transmit on 30, 20, 17 and 15m, I get a CAT error. It either shows that it cannot verify VFO or PTT state and wants me to configure the radio settings again.I am running Windows 7 64bit. I am brand new to FT8 and just starting using it last night. I tried searching for a resolution, but could not locate one.

Your help is appreciated,
