WIRELESS_REMOTE_TU_NING
Frequency-to-voltage converter for transceiver responds to AF output of control receiver and feeds corresponding DC voltage to varactor tuning diode in VFO of transceiver, for remote wireless tuning. In most cases only a few volts of DC variation across varactor are sufficient, so variable audio oscillator at remote-control location need have range of only a few kilohertz.-J. Schultz, H.F. Operating-Remote Control Style, CQ, March 1978, p 22-23 and 90.
