Technology: Longley-Rise Mapping Tool

Does anyone know where I can access one of these?  A new station is looking for one for their Industry Canada application

I'm not sure if this is exactly what you are looking for, but Nautel offers a radio coverage tool on there website that is based on Longely-Rice.  It's web based and you have to sign up for a free account, but it is free to use.

There is also a free (I believe) piece of software that we use called RadioMobile. It's a bit tricky, but I think I've mastered it for our purposes. I'd be happy to give advice if necessary.

Longley-Rice is a propagation model for predicting the reach of radio signals.  The great thing about it is it is terrain-sensitive, so it is very handy in areas of uneven terrain such as mountains/valleys.

CRC has a free tool online that uses Longley-Rice.  It’s free to use but requires a person to sign in.  If you don’t sign in, any parameters you enter into the form are deleted!

The web address is here:

Unfortunately, the tool seems to be down right now, which does happen from time to time.  I emailed someone I know at CRC to see if they can get it up again.

Other than that, the transmitter manufacturer Nautel has a free coverage planning tool in their RF Toolkit.  Again, free to use but you need to sign in to use it.  I don’t recall exactly if it uses Longley-Rice or another propagation model.

There are other tools available, but these are probably the easiest to use.  Hope this helps!
