The HT-3 was a 50 Watt marine transceiver of 1938 vintage. The transmitter operated on 3 crystal controlled channels in the 2.1 to 2.9 MHz band. The two-band, six-tube, tunable receiver covered the broadcast band and the 1.9 to 3.1 MHz marine band. The unit was powered from 12 or 32 VDC depending on the power supply choice.

The HT-8 shown on the left or above was a 25 W marine transceiver of 1939 vintage. The Superhetrodyne receiver had a seven tubes and the transmitter had four. A rectifier completed the 12 tube lineup. It operated on any of 5 Xtal controlled channels in the 2.1 to 2.8 MHz range and, with slight modifications, up to 6.6 MHz. The receiver also had one additional channel for a 2 MHz marine weather frequency. Later production of the unit had a socket to connect an external Western Electric type 104A ringer unit for selective calling. The purchaser could specify a power supply for operation on either 120VAC or 12VDC. The power supplies were external units, and 12 VDC supply was dynamotor operated.

The Model S-22 Skyrider marine was a tunable Superhetrodyne receiver of 1938 vintage. It had 8 tubes and covered the frequency range from 0.14 MHz to 18.5 MHz in four bands. It operated from 110 Volts AC or DC, and because of the lack of a power transformer the unit chassis was isolated from the cabinet.
