	M-90D TO FT-2980 Impedance Matching and Gain Circuit (Using BC547C) PUBLIC Small circuit to impedance match a Yaesu M-90D microphone to a Yaesu FT-2980. This circuit has a preamp based on BC547C set for adequate gain. (Use "mic gain" 4-6 on the FT-2980) by w6wwr \| updated September 28, 2025 2-meter amateur-radio ft-2980 gain ham-radio impedance-matching m-90d preamp rf-resistant yeasu
