Licensed AM broadcasters can obtain specialized components to keep their stations on the air.*
The TR.6000 AM Radio Transmitter Model 15.73 is a tried and true workhorse solution for 0-10 watt AM operation. Both new and preowned units are available.

Employed for emergency and temporary requirements, this model consumes only 1RU in height, with standard 19” rack-mounting ears. It delivers a high quality AM signal on any AM frequency. Its input accepts balanced 600-ohm audio; the RF output connects to standard 50-ohm cable.

Use the TR.6000 Model 15.73 in conjunction with an existing antenna system or email us to ask us about available new or preowned antennas, supports and groundplanes.
