I was able to get the MINIMUF program from Dec. 82 QST working "correctly" on my C-64. I put the word "correctly" in quotes because I feel some erroneous assumptions have been made in the design of MINIMUF. Specifically, the program consistently predicts ridiculously high MUF's during the summer months on northern paths. For example, try the North America - Europe path for a solar flux of around 200 (near the peak of the sunspot cycle) during July. Then think about your own experiences on 10 meters during July a few years ago. I have another program, obtained third hand. The person who gave it to me says it was in one of the RSGB publications. This program gives the LUF (based on assumptions I don't know), MUF and HPF (highest possible frequency). The results this program gives are far more believable than MINIMUF. If there is interest, I will post on the net. 73, Steve London, N2IC dnews
