[TowerTalk] tool to retrieve data and build HFTA profiles

[Dick Green WC1M]

This sounds terrific, Jim, and will be a huge boon to the amateur radio
community.

One question: are you proposing to generate .pro files with data out to the
full 50-60 miles, or just what HFTA can deal with (5000 meters, I think)?

73, Dick WC1M
