Will take your word for it.... been many a moon since I looked at the RAF en route supplement for lars units - I seem to recall even then tho that they were sparse.
Abington - when setting up your com plan - don't just look for LARS units - look for A/G stations and also airports/airfields that do not provide LARS if you are in an area where they are sparse - at least dialling those up and listening in may help,
If you had a UHF box, I would sell you the military low flying frequency!!!
