A liitle about the repeater

Both repeaters are located HERE, on the roof of Bath University overlooking the historic city of Bath

GB3UB is the 70cm 433mhz voice repeater and operates on 433.100/434.700mhz, ctcss 118.8hz. It uses a converted Storno base station using G8CUL logic running 10w to two Jaybeam folded dipoles. It provides hand-held coverage around the city of Bath, out towards Chippenham, down towards Midsomer Norton and across towards Westbury. It is internet linked via Echolink (node no. 201135 )
MB7UB is the APRS data digipeater.

You can find out what I do in my day job HERE.

More playing.

The Echolink seems to running OK. I have changed the Internet feed. It was running of a range extender but that was messing with my house WIFI. I am now sharing the Internet from my weather and APRS laptop. It has been fine all day but I will monitor it to make sure it doesn't time out or go to sleep. I have also adjust the aerial and made some slight audio adjustments which seem to have improved things. Ant comments would be most appreciated.

Echolink Changes

You may have noticed the Echolink callsign has changed. This is due to the link now being located at my QTH. John G4OTJ has hosted this for many years and I would like to thank him for his work over these years. At present it is working on an indoor beam so the signal may not be as good as it could. I will hopefully be able to mount this outside. In the meantime please let me know of any problems you have.

GB3UB, now OK

Following the problem with the repeater not retransmitting a visit was made today. We checked all the settings which were OK, but as a result of plugging a computer in it seems to have cured the problem. Hopefully this was just some form of problem with the logic CPU.

Logic problem

It appears the logic at UB has became corrupted again. I did make a visit today and made a hard reset but to no avail. I will try and make a visit soon with a lap top and reload the logic. The repeater is still sending an ident.

Unlicensed operators

It has come to my attention that unlicensed operators are using the output of GB3UB (433.100) These appear to be hot air balloon operations. This is actually much more serious than it first seems. There are special frequencies for  Hot Air balloons and all pilots must hold a air radio licence, also amateur radio is not permitted in any airborne vehicle. The consequences of interference to them is extremely serious.
If you hear  any operations please contact me immediately. use messenger, email or text. Please try to obtain a company. I will be contacting local companies to inform them of the interference, but may need to contact Ofcom if no joy. Please do not make contact with them as this is in contravention of your licence.

UB Update

Was planning to visit tonight but other commitments have prevented it. A visit is now planned for Wednesday evening. I know this is not ideal and many of you will be disappointed, but as the repeater, although not re transmitting is still sending an ID there is not an immediate need to shut it down.

GB3UB Off air

Sorry, but it appears GB3UB is off air. I have someone having a look latter and hopefully will just require a hard reset.

26 February 2018

All repeaters back on air

All the repeaters at Bath Uni came back on at 1738, today 26th Feb 2018. There are currently no plans for any further disruptions.

22 February 2018

Temporary Closure of GB3UB, MB7UB and GB3UT

Work is finally starting on the building where the repeaters are located. While, there are no plans to remove the aerials yet, we feel it a good idea to shut them down while there is a chance that a feeder could be cut or damaged. Therefore, the repeaters will be switched off around midnight on Friday 23rd February 2018. It is hoped, that should no disasters happen they could be back on early next week.

07 February 2018

UB held open

GB3UB is currently being held open by a regular pulse signal. I assume this is a car key fob. Hopefully the vehicle will be removed soon. If anyone is local perhaps you can check on the input. The repeater is still fully accessible, but with the noise in the back ground.

P.A.T. testing

As part of the  system at the University all mains equipment has to be P.A.T. tested. This will be happening next week. It will be during the day, and I cannot see any major problems. As regard the move, I have not received any updates. Both repeaters continue to work with no problems.
