[TenTec] Critical F2 Frequency data?
Fri, 9 Apr 1999 12:31:25 EDT
A little off topic, but things are slow on the reflector today. %^)
Does anyone know where a ham like me [or you] could find real time critical
F2 frequency data? You know, the critical frequency below which the F2 layer
reflects radio waves? My usual source
<http://www.ips.gov.au/asfc/data/ion/usa/rusmap.gif> has been bungled since
the 6th of April 2100 UTC.
Ten Tec Tie In: I'll be using my Corsair I during the QRP contest this
weekend, and want to know when to kick in the NVIS aerial, and when I should
move onto other modes of RF radiation.
Thanks and 73,
