G-QRP weekend
Last weekend was the G-QRP Club Convention weekend in Rishworth, Yorkshire.
The G-QRP Club is the British low power Ham radio club, each year they meet up for a weekend for a time of socialising, building a project and attending a flea market type rally with a couple of lectures thrown in. I've been for the last 4 years and always enjoy myself.
This year the buildathon project was a Solar powered 80m CW transmitter with an output power of 20mW (yes, 20 milliwatts!).

The solar panels are from garden Led lights and provide just enough power to charge the batteries during the day for an evening of operation. The transmitter is very simple, just one transistor in a Pierce oscillator circuit followed by a low pass filter.
