Interested in building a two tube AM radio transmitter very similar to this version? Buy the Catahoula Technologies Two Tube AM Radio Transmitter PCB. Some fellow ARF (Antique Radio Forum) members offered to send me some parts to get started on a quite successful 6888-based AM transmitter. The 6888 is an oddball octal tube that goes by the description of "dual control pentode" because its first grid and supressor grid both are used as a control grid. In the kit design, a 6AB4 or 6C4 is used...
The purpose of this 1 watt am/cw transmitter circuit is to develop a 3 stage broadcast pattern circuit. The primary components you need to build this simple tool are: a) Collector modulated AM oscillator with an amplifier and b) Crystal oscillator integrated circuit.
An FM transmitter circuit is a high frequency wireless device which is able to transmit voice signals into atmosphere so that it can be received by a corresponding FM receiver circuit for reproducing the voice signals in a loudspeaker. Here we’ll discuss how to build small FM transmitter circuits using 10 different methods, one that […]
