Hello Dave,
although it is not a precise answer to the problem mentioned by the friend of yours i have just thought he could visit a webpage devoted to lightning  strike radars (homebuilt):
http://members.home.nl/fkooiman/lightning/
he should go to section 7 ( manual and documentation); find and read a survey article written by John Silver ( likely,  UK based fellow as it follows from his e-mail address)
Mr Silver mentions a software which is capable by special time synchronization routines and triangulation methods to  make a positional fix of the ligntning etc..
a link to software developers is also given so i think he might have got a nice start to his specific issues with alfa stns ..
there is also a similar page: http://users.edpnet.be/DanielV37/Detecteur3/  dealing with the same problems
BTW .. those antennae and amplifiers built for lightning radar purposes are within the range of 10-11 kHz so "Dreamers" should also look into this at least to see really nice pictures of detected strikes..

i hope it will bring some help.. yours,  Piotr, sq7mpj
