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.

MB7UB Back working

Had some spare time today as I had a 'split' duty so made a site visit. Turned out to be a cable fault, which is a little strange as the TNC and radio sit on a shelf. Anyway I did not have the tools to remake the connector but have left it working OK. I plan to make another cable for a TNC 220 I have acquired. Anyway it is all back working.

No Site Visit

Had planned a site visit after work today but a sickness bug put pay to that. I hope to make a visit in the next few days so sorry for the break in service.

Site Visit

Made a visit to site today and there was no noise. Checked the input arund the site and no data carrier noted. However, what I did notice was that a TV/FM aerial along with what looks like an amplifier has been installed VERY close to the lower dipole of GB3UB. This could be the cause of the problem which I would assume that given the proximity of the amplifier to UB would also mean interference to anything connected to it. I also tidied up MB7UB and adjusted the volume and squelch control. However, that now seems to have stopped repeating anything so I will have to go back and have a look in the next few days.
For those of you about in the Midsomer Norton area we will be running GB1WFD from Sommervale School tomorrow from 1500- 1830 with set up around 1300.

GB3UB Noise uodate

Well the noise is back on UB. It must be a very weak carrier some where on the site as I can still access the box from the depths of Midsomer Norton. I am making a site visit tomorrow lunchtime (Saturday) in an attempt to DF it.

Interference on GB3UB

Couple of weeks ago noticed that the squelch on the repeater was being held open by a data carrier. I assumed at the time it was a car lock. However, the same thing happened today, Saturday again. After talking to another user I was told the same thing had happened during the week. Anyway as of this afternoon the interference had gone. I will have a listen next weekend and if the same thing is happening will make a site visit for a bit of 'dfing'. In the mean time if you hear the interference could you email the times and dates so we can build up a picture of it. Apart from that the repeater continues to operate as it should.
