A BA1404 IC is used to generate a complete FM MPX signal. The chip contains all of the necessary circuitry. CI and R3, and R4 and C4 provide pre-emphasis. The transmitter runs on a single AA cell. L3 is 3 turns of #20 wire on a Ke drill (for a form). L3 is long. L4 is 4 turns #20 wire on `Me drill bit, spaced to %.
If monophonic operation is wanted, omit C5 and the 38-kHz oscillator components.

The manufacturer wrote that the amps are identical to those in certified it makes, and that the transmitters imported and marketed by SCMS “are by all intents and purposes the same models already certified by an FCC approved test lab.&rd
This is because most systems from the transmitter to the antenna are frequency-specific. This concept may seem foreign to some radio oadcasters. Generally speaking, today's solid-state , filtering, transmission line and antennas are
This is a two-translator project; open spaces are for gear that is already in operation for the first translator. The equipment seen here includes, from top, an Omnia.7 processor, Audemat RDS encoder and Broadcast Devices switch controller, used
