The site at
Pensarn Nr Amlwch houses our UHF voice repeater GB3AN.
In service since 1987 and operational on 434.800/433.200 the
normal split. Also at this site is GB3TM our first TV
repeater and a first for Wales. The equipment for both
repeaters is recent and currently working efficiently.
There is a change in the operation of
both repeaters, we were all used to accessing the
repeaters and they in turn would reply with
courtesy tones to acknowledge that access was
successful. This is no longer the case, GB3AR and GB3AN
only transmit whilst they hear and recognise a valid
input signal, so no pip tones. Unless someone answers
you or you’re able to listen to the repeater while
transmitting, you would not know that the repeater has
recognised your transmission! Please bare this in mind
when testing. I mentioned valid and recognised your
input transmission. Both
repeaters require a CTCSS tone of 110.9 Hz.
Both repeaters run at 20w ERP, again an
improvement of about 3dB over the old system.
This is that for the first time in over
40 year history of our group that we have purchased
commercial equipment rather than home brew as in the
