W6REK/B HF Beacon for Eclipse Science

PLEASE SEE http://eclipse.yak.net/


The plan is to operate before, during, and after the Aug 21, 2017, eclipse from Edgefield Country, South Carolina, USA.

This Bash script (for linux) sends a beacon on the frequencies and the powers shown on the SCHED= line.

It currently stays on each frequency about 40 seconds, with a 28 second transmission (plus time for the automatic tuner to respond).
