Ham is all about experimentation. Last night I setup tiny beacon based on my CW keyer. The message is my call sign and locator. As a signal generator I am using old HP3336A synthesizer. The output level of 6dBm was enough to reach few km away.
Few photos and a screen capture from QRSS grabber are here.
Next step: operate HP3336 remotely to shift phases, transmitting some low PSK mode. What is lowest PSK “normally” used?
