My next priority is to get a basic 500kHz WSPR TX capability in place, if only a few watts to my very inefficient antenna. Once I get a signal of any kind I can start to improve the antenna and ground system and see how reports develop. The most probable route will be a transverter using the FT817 as the prime mover using an SBL1 mixer and a small IRF5xx FET PA This may take a few weeks, but I hope to have something on the air in October.

500kHz TX activities - closer
In recent days there has been an upsurge in interest in WSPR beaconing on 136 and 500kHz with loggings now running into thousands whereas only 1 month ago there was hardly any WSPR activity on these LF bands. I am now regularly listening on both 136kHz and 500kHz WSPR.
