Hi Alan,
Yes, you're probably correct, but without knowing that 'detail' you coud 
easily misunderstand what it is suggested that unit could do.
Incidentally, it was GW4ALG, not 3. Steve says one of the reasons he gave up 
on 136 was the 'first RSGB repeater on the band' and it attracting 
'pirates'. I have never heard of an RSGB repeater on 136 and think it a most 
unlikely band to interest pirates. Maybe I'm wrong, I often am!
Vy 73,
Chris, G4AYT, Whitstable.
