The Drake TR-4C is an HF amateur band transceiver covering 80 through 10 meters (some sources say 160-10 m) in seven 600 kHz ranges. Modes include USB, LSB, CW and AM. Input power is 300 watts PEP SSB, 260 watts AM/SSB. The accurate VFO provides 1 kHz analog dial. VOX or PTT may be selected. Other refinements include: CW side tone oscillator, crystal calibrator, VFO indicator light, CW semi break-in, VOX or PTT for AM or SSB, heavy irritated cadmium plated chassis, separate USB and LSB filters and 1.7:1 filter shape factor. The right panel has various jacks including: headphones, mic and key.
