RF AMP Board - 17 meter rig at CU2JL
I built the one watt RF AMP circuit in W1FB's Feb 97 CQ article, but I couldn't get it to work properly. Lots of distortion. So I pressed into service the boradband amps in my 30 meter CW transmitter. This rig appeared in QRP Classics (VXO controlled 6 watter). I changed the bias from Class C to Linear with a simple diode and current limiting resistor. The broadband nature of the amps will allow me to easily use this rig on other bands -- just change the crystal and the output filter.
