[Lowfer] lowFER " SIW " WSPR-15 and OP-32 Report

[Garry]

David, thanks for the reports for a 627 mile path, significantly farther 
than Andy at 493 miles. I saw a station in VA was on the 2200m decode 
map at https://www.pskreporter.info/pskmap.html but wasn't sure if my 
lowfer was being decoded. Your SNRs make it seem likely wspr15 would 
have decoded too. It seems opera32 doesn't really offer better 
sensitivity. You never know for sure until you try. I know W1VD and 
W1TAG have studied about every known modulation scheme at LF but I think 
that was limited to a relatively short ground-wave path.
