A borderline insane 30m QRSS beacon project. The beacon contains an 8K EEPROM (28C64 chip) of which only 1K is used. It is programmed by hand from front panel switches.

A Two-transitor Transmitter for 30 Meters by KB4PY
When I decided to become active on the 30-m band, I wanted to build a simple transmiter. I have a Yeasu FT-101E that receives WWV on 10MHz. Others may have general-coverage receivers, and need only a transmitter.
