I should add , calling out on the pactor port works fine.

Btw, I would welcome suggestions on using SCS 7400 Dragon pactor/robust modem and RIGblaster Advantage sound-card interface I use for HF packet mode in parallel with a single HF radio. For now I use each of those devices alone, so I re-connect their audio cables when change from pactor to HF packet at the same radio in the local ham club. (Each device connects to the same MIC & headphones jacks on the front panel of the radio, FT-1000MP.) All works well.
I'd like to avoid re-connecting cables when change working modes, but to stay on the safe side regarding possible damages to either the club's radio and the modem & interface. (SCS 7400 and RIGblaster Advantage use two USB jacks of the computer, the former uses an external 12VDC power supply while the latter is energized by the USB jack. I suppose that in case of binding their audio cables together before the radio's jacks, there might appear some parasitic currents in the loop or like, and I wonder what might be the safest to do. Some folks here suggested to think about some filtering/shielding electronics in between the radio and that 'joint' cabling ...)
Any experience with?
