GB3JB - RV63 - Output 145.7875 MHz - Input 145.1875 MHz - 88.5 Hz ctcss (E) - IO81vc - South Wiltshire - England.

GB3JB is funded solely by donations and provides coverage across South Wiltshire, South Somerset and North Dorset, with specific areas such as the City of Salisbury, Salisbury Plain, the Blackmore Vale and Cranborne Chase being well within its range. Coverage also extends, for fixed stations, across most of central and parts of North Wiltshire, Southern Dorset and West Hampshire, plus parts of North and West Somerset - see link to coverage map.

GB3JB is an analogue voice repeater, with no internet linking, simple intuitive logic and no bells or whistles. The beacon gives callsign and locator. The invitation to transmit is a single dit, and to access the repeater users must continually transmit the 88.5 Hz ctcss tone. There is NO 1750 hz tone burst capability. The system timeout is currently set for 4 minutes.

The simple rules for using GB3JB ....

(1) Only use the power necessary - remember there are other repeaters on the same channel,
(2) If you wish to use another repeater on RV63, please turn off the 88.5 Hz ctcss tone otherwise you will still access JB,
(3) Please wait for the invitation to transmit (a single dit), and always leave a pause - please give others a chance to call-in, and finally .....
(4) Ignore any idots - If you don't hear a callsign, do NOT respond - EVER !

Antenna Replaced .....

Hi All,

GB3JB went off air at approx., 11:25 am, and came back on air at approx., 3:25 pm, today, 17th February.

The main antenna, as expected, was showing signs of considerable ware and the antenna assemble was loose in its machined mounting.  I guess that's what 4 years on a very exposed site, does for a standard amateur dual-band collinear.

The antenna was replaced and the feeder was re-run down the inside of the main mast, rather than down the outside.  This did require a longer feeder, approx., 15 feet longer, but this should have only a minor effect on the overall system capability.

Thanks to Chris G3VEH and Stephen M0SMM, for their invaluable assistance, it was very much appreciated, and further thanks to Neil G7EBY for his kind donation of the replacement antenna.
