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 )
MB7UUB is the APRS data digipeater.

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

Some pictures of the view from the site

Nice sunny day so some photos were requred. These do show what a fantastic site it is.

The callsign of the APRS digipeater has changed to MB7UUB. No other changes.

Echolink

 I have had serious issues with the Echolink since changing ISP. They don't provide a fixed IP as standard, and as such I have been relying on the Echolink proxy server service. This has now become unreliable to use with a link and I 'bit the bullet' and went with a fixed/static IP address. This has resolved all the issues and as such the link is now working as it should. I now just need to improve the signal into the repeater.

Working much better.

 Finally got another PC for the shack and the link. Running Echolink on a £3 soundcard which is working really well with audio levels 100% better than before.

Echolink revived

 Little update on the Echolink. After a little work the link is now working, still not 100% happy with the audio, but it is workable. Hopefully it will continue without any major issues.

Echolink

 Unfortuantly I have not been able to restore the Echolink link. To be truthful I have lost interest in Echolink. There are now multiple ways to access amateur radio via VOIP, I also struggle to access UB from here now which I suspect is due to trees and building work on site.  The NOV expires in July, so there is time for my interest to lift. Or of course someone else may like to run it.

Echolink down

 Unfortuantly the Echolink link is currently not working. I hope to sit and try and work out the cause in the near future.

Raynet Activity

 Tomorrow 16th October 2022 is the Bath Half marathon. GB3UB will be used by Bath Raynet to provide support radio for the event. The Echolink will be deactivated for the day.

MB7UB

 MB7UB, the APRS Digi has been quiet for a while and Covid prevented me from visiting the site. However, visit made on Friday and the radio changed over to an TMD-700. This seems to be working very well with a lot of stations being heard on RF. I will at some stage get the original set up sorted.

Update

 Just noticed this site has not been updated since last year.

The repeaters continue to operate without too many issues. I have had an issue with the Internet linking laptop. I have now resolved that by using a separate WIFI feed to it. having found my vertical had burned out and replaced it, I can now access the repeater without any issues.  


25 June 2019

Internet link relicensed.

Just a short note. The repeaters are continuing to work without too many problems. I have now received the NOV for the link for another year.

03 May 2019

MB7UB all legal

Just a short note to say MB7UB has had it's NOV renewed for another year. Much less pain than last year!!

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.

08 June 2018

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. 

06 May 2018

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.

04 March 2018

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.
