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.

MB7UB Upgrade?

For those using UiView/APRS in the Bath area will have noticed UB has been off quite a bit lately. The problem is that it runs with a VERY old laptop running Win 95! This is fine for what it needs to do. However, it appears the power supply on site seems to go off/spike/ etc. from time to time and the laptop resets itself. Unfortunately not back into UiView mode. I am very grateful to the fairies who seem able to attend the site and reset the system. I have at present sitting on the bench a Pac-Comm TNC-220 I hope over the next months get this working as a standalone digi, even running on a float battery to make things a little more reliable.

Repeater abuse

This is something that UB and 70cm repeaters do not suffer much from, thankfully. However, I have been listening on WR and there it is a different situation. So I thought I would publish some guidelines for you.

REPEATER ABUSE ADVICE

It is a sad fact of life that some persons appear to get their kicks from ruining Amateur Radio for others, especially when using repeaters.
This abuse can take the form of deliberate jamming, playing of music etc or even by stations making ingenious use of air time to deny others access while still staying generally within the terms of their own licence. Unfortunately recent months have seen an upsurge in abuse on many repeaters and the Emerging Technology Co-ordination Committee (ETCC) and Ofcom believe it is time not only to remind Repeater Keepers of their responsibilities in holding a repeater NoV but to also offer some advice in the management of abuse.
It is a fundamental requirement of their NoV that Keepers are responsible for monitoring the traffic passing through their repeater and taking appropriate action to prevent unsuitable content being transmitted. It is recognised that Keepers cannot do this continuously or to be in a position to take direct action against the offenders.
They are however in control of their own repeaters and in cases of persistent abuse should be prepared to switch it off for cooling off periods and to document and if possible record the offences taking place.
Contact should be made with your local ETCC Committee Member to discuss the actions available to you and to decide when further action by the authorities is appropriate. Members can advise on the methods that have been used successfully in other areas and on the keeping of suitable logs that will be of use in the future.
A list of ETCC Members is available here.
To assist us in dealing speedily with these issues we would ask all Repeater Keepers to make contact with their local manager so that lines of communication are established and we know who to talk to when problems arise.
We would also draw your attention to the Ofcom website where the following pages will be found helpful click here
The most relevant section from this document is reproduced below:
What should you do when you encounter abuse?

  • Do not respond to it. Experience suggests that abusers want an audience, so ignore them. Remember that you may be breaking your own licence conditions if you correspond with someone who is breaking the terms of their licence or who does not have a licence or if you try to deny them access by keying your microphone.
  • Do not approach or confront them.
  • If abuse occurs frequently, make a note of it. Write down essential details such as the date, time, frequency, location, mobile or fixed, what form the abuse took and any other factors that you think might be useful.
  • Maintain this log in order to build up a pattern of the abuser's operations.
  • Make sure the information you collect is precise and accurate.
Ofcom resources are directed primarily at Safety of Life services and as such it is incumbent on the Amateur community to do as much initial ‘detective work‘ as possible before escalation to Ofcom is considered.
The ETCC will work with you to address abuse issues but you must help yourself first by taking the action as outlined above.
