GB3NC Service area covers

most of Mid Cornwall from

our Hensbarrow location.


Input on 145.125 MHz

Output on 145.725 MHz

CTCSS tone 77 Hz.

GB3NC is also on Echolink

and it is recommended that

stations wait for the second

Pip to allow echolink to

respond and others to break

in on a QSO.

We also believe that Mobiles

should be granted priority

over fixed stations
