Transmitter Het PCB - Bottom Side

Shown is the Transmit Het PCB from the bottom side. All RF specific tuning capacitors are of the dipped silver mica type. Just to the left of the Transmit Het area is a drive system that connects to the front panel band knob assembly. This provides a right angle drive to the band switches for the transmit het section and the receive het sections. It continues through the drive unit to a chain drive assembly that also is connected to switches within the RF deck area.

The shaft you see going over the transmit het area into the RF Deck is from the Final Tune dial on the front of the radio.
