Possibly because most propagation prediction programs are predicting low angle 'DX' propagation? If you want the local F2 Critical frequency (the one where signals go almost straight up and down, try
OK, here is a question. Two weekends ago in the Sept. VHF contest we worked a few out west grids on 6M. It was difficult due to the fact that we were only copying 1-2 words/letters/numbers at a time.

Tomas: How does the MUF map predict availablity of a DX path for 80 Meter QSOs (which was the original question), or for 160 Meters? Are there better tools available for realtime display of current c
On the low-bands, ionospheric absorption is a limiting factor. The application PropView uses the IONCAP engine to generate predictions, plotting both the MUF-based limits on refraction as well as abs

--Original Message-- That's the 'other' map on that site. :-) The problem always seems to me to be that it is 'DX' that many people concentrate on, when a lot of the paths most people actually use ar
--Original Message-- Be fair, the original question was something like "why are there lots of signals when the propagation prediction software says the band is dead". Maybe I misunderstood? Do you me

Dave: Here was the original question, which wasn't mine: So, in fact, Chas was asking about NVIS, and I'm sorry for jumping the gun. There are, however, plenty of DX signals (3000 kM and more) on 80

Hello Thomas I am in the same boat as Stu. Propagation has always a deep dark mystery for me. I joined the reflector in hopes of learning more and clearing away the mystery. I haven't a clue as to ho
