GB3NC Service area covers most of Mid Cornwall from our Hensbarrow location.
The Yaesu DR-1X 2 metre repeater GB3NC is currently configured for FM analogue voice only and may be accessed with a CTCSS tone of 77 Hz or a 1750 Hz tone burst.
A few seconds of voice will latch GB3NC but do allow the 2nd “T” to permit possible Echolink traffic before resuming the QSO. The repeater Input is on 145.125 Mhz and the output is on 145.725 Mhz.
The repeater uses a radio infrastructure FVC6 co-linear with a gain of 6dB. The antenna is fixed atop our 100’ (33m) mast which is at 1000’ (300m) ASL on Hensbarrow Downs. GB3NC runs at about 10 watts with an ERP of about 25 watts.
Echolink is available, hosted by Roger Gregory G4OCO and the node number is 282184. It is recommended that stations wait for the second Pip to allow echolink to respond and others to break in on a QSO.
GB3NC is our primary repeater for mobiles around the county of Cornwall - we believe that Mobiles should be granted priority over fixed stations.
We host the RSGB news on Sunday morning at 09:30 hours with a roundup for reports afterwards.

Stations transmit digital pictures on 2m, 70cm and 2m and receive television pictures using the 23cm band.
Stations using GB3NQ may use relatively cheap 23cm transmitters and receivers using one of the Portsdown or Minitioune/Ryde projects available from the BATC (British Amateur Television Club) or suitable DVBS-2 satellite set top boxes -check suitability before purchase. https://batc.org.uk/
The input frequency is 146.5 Mhz, 437Mhz and 1249 MHz and the output 1316 MHz. Although GB3NQ has audio through, stations often use talkback on the 2 metre frequency of 144.750 MHz or via GB3NC repeater on 145.725Mhz.
The repeater transmits on 1316MHz 1Ms/s FEC 2/3 DVBS-2.
GB3NQ was originally constructed by two local amateurs. Maurice G3WKF and John G0VDU. Maurice, a mechanical engineer, made the high quality filters for the input and output of the repeater and also the 4 faced lantern antennas required for the transmitter and receiver which are still in use today.

The Mid Cornwall Beacon and Repeater group host six beacons at our Hensbarrow Downs transmitter site. The locator is IO 70 OJ and the bearings are all to the North East from our far SW location. The beacons operate around the clock all year round. They are a significant cost to us. Our Beacon keeper is Nick Camp G7KFQ who is always pleased to receive reports.
Our 2 mtre beacon is unique in that it has two antennas. One to the North East and the other to the South for French, Spanish and further afield contacts.
