W5OLF 10m WSPR beacon

Many years ago I bought a WSPR TX beacon for 10m from Jay W5OLF. It is still in almost daily use. I am not sure if it is still available. It produces 500mW on 10m.

In better years it has been spotted all over the world. It is about the same size as a pack of cards and is totally self contained. No PC is needed.

The only antennas here are simple end fed wire antennas. More recently, the only 10m antenna is my indoor loop.
