I inherited a YAESU 1000mp transceiver and have my old headset from military days. I want to use the headset on the 1000MP. Mic impedance on the 1000MP is 500 to 600 ohms and audio output is 4 to 8 ohms.
The headset data I retrieved shows mic impedance of 4 to 6 ohms and earphone of 19 plus or minus 2 ohms.
Would appreciate any info on what I need to match the headset to the 1000MP
