Solar Data and HF Propagation Tools have Moved!

Click to go to my Solar and HF Propagation Page. Sorry all, but it was to hard to maintain in two places, and this page was geting to big. Either click on the image to the left, or on this link http://www.hamqsl.com/solar.html to go to my Solar and HF Propagation Website. It still has all the tools, conversions, and a lot more. If you are interested only in the solar and HF propagation data, then you can bookmark that page.

Autopatch (Open)

NOTE PLEASE READ! The RLC-3 controller will not place your call while it is ID'ing. When the repeaters have not seen activity in a while, they ID when keyed. So if you enter an autopatch command it will wait until after all five repeaters and one link ID to place the call. After you enter the A+number, give it some time to ID and complete the call.
  • Autopatch connected to dedicated phone line, and is open for all to use.
  • Autopatch calls limited to 3 minutes
  • Accepts all local 7-digit calls and toll free long distance (1800, 1855, 1866, 1877, and 1888). No other long distance allowed.
