RADIO SYSTEMS INC. "PHASE II" AM BROADCAST
Up for sale is a fully functional and operational Radio Systems Phase II AM Broadcast Transmitter crystal tuned to 1100 kHz.
System can be used for Carrier Current operations with optional CP-15 Coupler (Not Included) or setup as a "Leaky" Cable System with special coax and proper 50 Termination. System can also be used as "Single" Conductor (Antenna) system as the antenna needs to match less than 2:1 VSWR for proper operation. This transmitter will produce a full 20 Watts Max of output RF Power (Adjustable from 100mW to 20Watts). This transmitter is crystal tuned to transmit at the frequency of 1100 kHz and is not adjustable. Crystals can be easily replaced inside the transmitter.
Change of Frequency crystals can be purchased from 3rd Party vendors such as: http://icmfg.com/index.html to change transmit frequency if so desired at a later time. (I do not carry extra crystals).
