GB3UB MB7UB The Bath Repeaters: April 2008

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.

Echolink

Echolink is currently off on UB. This is due to a computer failure at G4OTJ. However, this has given John a chance to try some new software. This is SvxLink which runs under Linux.
I will post updates when available.

GB3JB CTCSS tone change

This repeater has a large coverage so thought I would show this here as well.

GB3JB: Change of CTCSS tone

From Jan G8CYV:

Hi All,

As the regular users of GB3JB will have noticed, we have recently been suffering from interference from users of GB3PC, who put a strong signal into the ‘JB’ site and are splattering across the ‘JB’ input frequency, presumably as a result of not have a narrow deviation capability on their equipment.

Because GB3PC has the same ctcss tone as GB3JB, this has resulted in our repeater opening up at various times, and retransmitting the splatter along with the invitation to transmit tone, for, in some cases, significant period of time.

We can obviously do nothing with regard to the stations splattering across the ‘JB’ input, other than to perhaps ask all operators to switch to narrow deviation setting, if their equipment has that option.

Therefore, following on from communications with our zone manager on the ETCC, in an attempt to reduce the potential for interference, and to stop ‘JB’ opening up, as described above, we have decided to change the ctcss tone that is required to access ‘JB’, from it’s current 71.9 hz, to 88.5 hz. Obviously the tone transmitted by the repeater will also change to this new frequency.

The change will take effect on the 1st May.

In addition to emailing this information to all on the blanket email update list, we will be adding it to the web site. The ETCC will also be changing the data on the “ukrepeater.net” web site. However, it would be appreciated if you could mention this to all those that you work via ‘JB’ and simplex, in the intervening period, as there are more users of ‘JB’ than we have on the email list.

It would also be appreciated, if those associated with radio clubs etc., within the ‘JB’ coverage area, could bring this information to the attention of their members.
