1900z MAINSAIL with PRC-160 field demonstration test 10 and a test count.  Interesting.
2109z SCORE11 with test count.  Then asking for r/c

[~SIGINT~]

I suspect that the PRC-160 field demonstration test is referring to the Harris FALCON III AN/PRC-160. This is the latest generation in the evolution of HF radios from L3/Harris and has been fielded by several NATO countries, including Canada.

L3HARRIS FALCON III® AN/PRC-160(V)

Only tuned into the #10 test count, but I did hear on it simulcast on all 4 HFGCS frequencies.  A listener on another list heard these at 15 minute intervals.
