Automatic CW keyer, 4-channel sequencer and simple computer interface for PTT switching and CW manipulation. Modulation of a magnetron might be a possibility using phase shifters, but spectral purity requires improvement. This would drive a W6PQL XRF-286 amplifier nicely. 6m Projects - Amplifiers 1 KW 6 Meter LDMOS Amplifier by W6PQL You only need a bit over 1w in for a KW out on this one; the amplifier shown here has an internal 16db attenuator so it can be used with drivers in the 50 to 100w range. Following my recent amplifier build for QO-100 I decided to scrap the power hungry Spectrian board. Op de 23 cm band speelt vliegtuigscatter een veel grotere rol dan op 2 meter. Se siete degli appassionati dei 23 cm sicuramente avrete fatto un po’ di zapping su internet alla ricerca di informazioni e progetti. Several companies offer 23cm amplifiers, though, including DEMI and W6PQL.
