So, if you convr you lat & lon to the same datum as the radio mobile stuff 
then you would be in the right place?  There must be a reletively simple ( 
i.e. programatic) way of performing datum conversion on sets of data.

it looks like there is a data file (radiosys.dat) that is used for saving 
the system (Node) spcific data. - again this could be generated form an 
extract from the current locfinder data.

It looked ot me that the radio mobile stuff wasn't very strong on the 
mapping side, but it was pretty detailed on the working out LOS amd signal 
strength.
