Hi All,
Sorry, but I had to switch JB off again this morning. At approx., 10:30 am.
It appeared to be not quite right when I checked it at around 9:30, so I decided that a trip to the site was called for.
Upon inspection, one of the two 12 volt 135 AH batteries, that are connected in series, to produce the primary 24 volt d.c. supply, was basically dead. The on load terminal voltage, was down at 5.3 volts ! Probably un-recoverable now. The other battery was at 9.9 volts.
I have therefore switched everything off. Although I have left the turbine, which was turning a slow but steady rate, connected to the batteries, while I attempt to resolve the situation.
The only comment I would pass at this time is that in every case, so far, where we have had trouble with the 24 volt supply, irrespective of the type of battery that has been installed, it has been the lower battery, i.e. the one sitting with the negative terminal at zero volts, that has discharged faster than the other. i.e. the battery who's negative terminal has been sat at the 12 volt level.
The only other comment I would make is that we did not have so much trouble, in this respect, when the 24 volts capacity was made up of a series / parallel network, of lower capacity batteries.
Anyone any ideas ?
So until I can get the combined intelligence of the Technical Team to resolve the problem, this could be on going for a while.
I will try to have something sorted on a temporary basis, tomorrow (Sunday 24th July), but no promises.

RV63 - Out 145.7875 MHz - In 145.1875 MHz - 103.5 Hz ctcss (G).
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.
The simple rules for using GB3JB ....
(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.
(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.
(8) Ignore any idots - If you don't hear a callsign, do NOT respond - EVER !
