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 !

GB3JB UPDATE - 26th Feb 2012

Hi All,

Well, it's taking a time, but things really are progressing - HONEST.

I can report that the new dump load system, is taking shape, and construction is moving forward.

There will be several staged additions to get to the final system up and running.  These, will also involve changes to the repeaters main controller, however, the first stage should see "JB" back on air, in the not too distant future.

I must stress that a lot of effort is being put into this, and "JB" will NOT come back on air, until we are certain that we can safely run the system without the risk of writing off another dump load and another set of very expensive batteries.  NEW batteries are already available for installation.

With regard to the damaged antenna mast, and antenna.  As previously advised, a replacement antenna is already available, and there are various options available, regarding a replacement for the mast.

Please be assured that we WILL get GB3JB back on air as soon as we can.

Finally, a BIG thank you to all who have recently made donations for the repair / maintenance of the repeater, they are very much appreciated.

Cheers & 73

Update - Current Situation ...

Hi All,

If you are having withdraw symptoms, from JB, I'm very sorry.  However, things are moving forward.

There has been much discussion (exchange of e-mails, re ideas, etc.,) amongst the technical team, and Andy, G0JLX, has been putting in lots of time and effort, in coming up with the design for a NEW, as it was described to me, "solid state" dump load.  I believe that this is now starting to take on some form of physical as well as theoretical, shape.

But, don't get too excited, there is still significant work to be done in this area, and the new system will of course need rigorous testing, before installation.  As Andy put it, "I hope to be able to design and build a very robust solution that will provide JB with a really first class solution for the long term."

With regard to the batteries and the antenna/mast.  This is all in hand.  Replacements are available.

Thank you to all who have kindly offered / provided support, both in terms of replacement hardware and financially.  It is very much appreciated.

Thanks to all those of you who have contacted us, with suggestions and offers of support.  As far as I am aware, either I or Jan have responded directly to you.

We'll attempt to keep you all up to date with developments, as best we can.

Cheers & 73
