[vcf-midatlantic] 1968 Longley-Rice model in Fortran IV

[Mike Markowski]

I just subscribed to the list last week, still getting a feel for topics 
and hope this one is of interest.  I was recently looking into the RF 
propagation model by Anita Longley and Phil Rice, still widely used 
after a half century.  Going from one old report to another, I found the 
original 1968 CDC-3600 Fortran IV source code as an appendix in a 
report.  After correcting the many OCR errors with O/D/0/Q, I/l/1 and 
similar, I posted about it to the PiDP11 mailing list.  Several folks 
joined in and the code now runs on several old OSes in addition to F77 
if you want to run it on linux.  The output is, well, admittedly not as 
fun as a game, but if you want some contemporary code for your retro 
computing or happen to also be an EE working in RF, it is at
