RV63 - Out 145.7875 MHz - In 145.1875 MHz - 103.5 Hz ctcss (G).


GB3JB is funded solely by donations from its' users and supporters. There is no club or group to join and no annual membership fee. We rely totally on your good will.

The system is located in South Wiltshire, in IO81vc, 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 coverage map.

GB3JB is an analogue voice repeater, with no internet linking, simple intuitive logic and no bells or whistles. The beacon sends callsign and locator. The invitation to transmit is a single dit.

To access the repeater, users must continually transmit a 103.5 Hz ctcss tone. There is NO 1750 hz tone burst capability.

The system timeout has been reduced to 3 minutes, so please set your rigs' TOT accordingly.

The simple rules for using GB3JB ....

(1) GB3JB is available for ALL Licensed Radio Amateurs to use, be they 'newly licensed' or an 'old timer'.

(2) All users of GB3JB are expected to operate their station within the terms of their specific licence conditions and restrictions.

(3) When in QSO, please wait for the invitation to transmit (a single dit), and always leave a pause between overs' - always give others a chance to call-in.

(4) Please use good operating practices and procedures. Mobiles have priority. Remember, if a station calls in, during the gap between overs', always acknowledge them and please DON'T leave them sitting on the side, while everyone else has an over.

(5) Only use the minimum power necessary - remember there are other repeaters on the same channel. The repeater only transmits with 25 watts ERP, so if its' 5/9 with you, you don't need to use 50 watts to a high gain vertical, when 5 or 10 watts will do. If you use 25 watts ERP, then the signals strengths should be reasonably reciprocal.

(6) If, under lift conditions, you wish to use another repeater on RV63, please turn off the 103.5 Hz ctcss tone, otherwise you will still access GB3JB.

(7) Remember that you are Radio Amateurs, using an Amateur Radio facility, so please use the appropriate operating practices and procedures.

Since you have taken the trouble to get an Amateur Licence, surely it's not to much to expect of you, that you use Amateur Radio abbreviation and accepted terminology, such as the Q-codes. We do not have a '20', we have a 'location' or 'QTH'. We do not have a 'personal', we have a 'name', etc., etc., If you still use CB, that's fine, no problem, BUT please leave the CB lingo for CB, and not when you use GB3JB or any other Amateur Radio facility or the Amateur bands.

and finally .....

(8) Ignore any idots - If you don't hear a callsign, do NOT respond - EVER !

We Need YOUR Help

Hi All,

Sorry, but I have to advise that GB3JB, has had to be switched to LOW Power, approx., 10 watts ERP.


Problem No 1.

It would appear that a bearing in the wind turbine may have gone, as it is no longer turning !

Therefore, the only power source, keeping the batteries topped-up, is the Solar Panel. Hence the reduction in output power.

We therefore need to lower the mast which has the turbine on it, so as to do an inspection and determine the actual problem, and organise the repair.

This gives us two further problems.


Problem No 2.

As some of you may be aware, I am, (as is the case with several other JB supports,) recovering from major Heart surgery, (a quad bypass) and am unable to assist Clem, with this urgent requirement.

We are therefore looking to you, the users and supporters, to offer your physical assistance.

The last time we had to do some work on the turbine it took 4 of us, and we only just managed it. I'm unavailable, and my Son is currently in the Golf - Pirate Bashing, as he puts it.

Clem will need the help of 3 or preferably 4 strong individuals, to assist with the lowering of the mast/turbine assembly. This is a total of around 135 Kgs, with the bulk of the weight being at 20 feet in the air.

At least 1 of the individuals will have to be happy, up a ladder, (that's usually my role, HI.).

As I am not going to be able to take part in the fun and games, Clem would like anyone who is able to offer assistance, to make direct contact with him, AS SOON AS POSSIBLE, via his e-mail address: clement.tabor@btopenworld.com


Problem No 3.

As most will be aware, GB3WX the 6m/10m Cross-band repeater and beacon system is located at the same site, as JB.

As you are also aware it is currently off-air whilst we are resolving a breakthrough problem, associated with JB. The GB3WX ident is getting into the GB3JB system and being re-transmitted over GB3JB, when JB is in use !

This system takes significant levels of power, approx twice as much as JB, and therefore GB3WX will not be put back on air, until the turbine has been repaired, even if the breakthrough problem is resolved, prior to that time.


SO FOLKS IT'S OVER TO YOU - WE REALLY DO NEED YOUR ASSISTANCE ....


Let's keep our fingers crossed, that we have lots of clear, bright, sunny days, with lots of UV, over the next few weeks, while we get the turbine problem sorted.


Cheers & 73's
Dave, G3ZXX - GB3JB Team
