Hello,

A while back I saw a program that could have two grid references entered
together with rough antenna heights and power etc. The program give a side
view of the path and terrain. This was used in the UK and a DOS program.
It also calulated the path loss and put a line between the two sites to show
how the signal would be blocked by hills for example.
Anyone know what it is called or where to obtain it from ?

It was written by G4JNT, and it contained a real UK terrain database. It
hasn't been supported for ages, but one of the UK microwavers may still
have a copy.

There are much more accurate VHF/UHF propagation programs around now,
with more detailed UK terrain databases and also better-verified
propagation models, but AFAIK they are all proprietary.
