The transmitter he had was the HT-37, a complete table top rig providing SSB, AM, and CW output on 80 through 10 meters. It featured 144 watts plate input on sideband, both sidebands transmitted on AM, and included a built in VFO. Price: $450.

In addition to the receiver and transmitter, the Heath Reflected Power Meter is seen on top of the HT-37 on the right side of the operating desk. W0BXI used the popular C-D-R rotator model AR-2 to turn his beam, which can be seen just to the left of the HT-37. The microphone was the Astatic 10-D dynamic.
