Hi Andy,


OK & thank you for your comments & advice.

It could quite well be just the Mk2 & G versions, but I will wait until 
there has be time for more users to reply.

I have an cheap option on a Mk1 (although it is not labled as Mk1), the 
abvious difference is the Mk1 has not got 70cms.

I may be able to borrow it & make some tests.


73, Gary - G4WGT.
