GB3AR is our 2mtr repeater sited in an enclosed site Nr Waunfawr 5mls south of Caernarfon , and interestingly only a few hundred yards from the old Marconi transmitting station. This was the groups first repeater inaugurated in 1976 and to some extent is the flagship of our Network. AR is on 145.700 mHz
with its input at the usual spacing 600 kHz lower. Ecolink is operational on AR usual protocols.
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 past.
