Leon, it's hooked up just like it instructs in the manual..... rigblaster to FT-1000 MP MK-V mic input in front with supplied mic plug. MD-200 Mic plugged into 8 pin plug on rigblaster's front panel. DB com port plug goes to computer for keying. Audio from sound card to input on rigbalster, speakers to audio out on rigbalster.... What problems are you having? Ron N7ZM
