G3XBM – ham radio blog: Simple LF/MF QRP transmitter

January 14, 2010 | Amateur Radio | By: Mark VandeWettering

G3XBM posted a link to VE7SL’s nifty LOWFER beacon transmitter, setup to run around 188khz. I’m still fascinated by LF operation under Part 15, and this circuit is just about as simple as you can get. Very neat. Preserved for later consumption.
