Standard techncial stuff here, you worry about connections for Push to Talk (PTT) and Microphone audio -- AND proper imput impedance of FT-101B versus the output impedance of the microphone (Turner).
Turner, originally in Cedar Rapids, IA was purchased by Telex and is now part fo teh Telex/EV organizaiton.
BAMA web site has the original Turner Wiring Booklet (rare to find in print) -- Look at page 24 for Yaesu FT-101 wiring
