	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
	ECGR 3131 Project 1 PUBLIC by ejoya \| updated April 23, 2014 common emitter gain
	Two Transistor Amplifier PUBLIC Two transistor amplifier. Gain of about 30 times (inverted) and low impedence output. by luigi.maroni \| updated September 30, 2013 amplifier emitter-follower gain transistor
	Wien-bridge JFET PUBLIC by cbooman \| updated January 17, 2013 agc feedback-oscillator gain jfet oscillator wien wien-bridge
