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 having a narrow deviation capability on their equipment.

Because GB3PC has the same ctcss access 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 periods 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 a 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 this could be mentioned to all those that you work via 'JB' and / or 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 *filtered*ociated with radio clubs etc., within the 'JB' coverage area, could bring this information to the attention of their members.

Cheers & 73's
Dave, G3ZXX.
