GB7JB is funded solely by donations from its' users and supporters. There is no club or group to join and no annual membership fee. We rely totally on your good will.

The system is located in South Wiltshire, in IO81vc, co-sited with GB3JB, and provides coverage across South Wiltshire, South Somerset and North Dorset.

GB7JB is a 70 cm Digital voice repeater, based on DMR TDMA Mototrbo technology.
It provides TWO simultaneous channels. One is for local chatting, whilst the other is connected to the Regional Cluster / Network.

Well, the news we've all been waiting for ... the minimum of £1600 of donations have now been pledged, by 39 individuals, in 70 days.

To the 39, thank you all very much indeed.  GB7JB, will now definitely be going ahead.

However, that does not mean that those of you who have been holding back, to see if it will actually get going, can now forget all about it ... hi hi.

The £1600, gets GB7JB going, I will still need to find around an extra £300, between now and the end of February, to cover the increased all risks insurance cost and the cost of internet fees, associated with connecting the system to the Regional Cluster / Network, via the internet.

I have asked Peter, M0ACD, who acts as my Treasurer and who deals with all things financial, to set up a PayPal account and a Bank Account, so that all financial matters relating to GB7JB are kept totally separate from the GB3JB accounts.

The PayPal account is now available, but PLEASE make sure that you select the "send money to family or friends" or "donation" option, otherwise we have to pay fees, and don't get your full donated amount.

The e-mail address that you need to make the PayPal payment to, is:

With regard to the Bank account, it seems like it's going to be no simple feat to set it up, despite the fact that there is already an existing account for GB3JB, run by Peter M0ACD, at the same bank ... what a pa-lava.

Funny, our banking regulations seem to be designed to protect Banks from us, but NOT us from THEM !!!!!   But I digress .... hi hi.

I do not expect any payment this side of New Year, but do expect all pledges to be honoured by the end of January.

If, however, you wish to make your pledged donation, now, you can use the PayPal, link, to the left of this posting.

When making your donation, PLEASE also include a short message, in the box provided, indicating your Full Name, Callsign and e-mail address, so that we can link your donation payment to your earlier e-mailed pledge, or log it as an unexpected donation.

Between now and early February, I shall be organising the various other bits, batteries, inverter, duplexer, and the installation of the replacement antenna.

The existing antenna having been damaged by some rather large Raptors, that fly around the site, and use the tower / antenna radials as perches.  They've not been very kind to the radials .... The replacement antenna, does not have any radials .... hi hi.

So folks, thanks to all who have again shown their faith and trust in me.  It really is very much appreciated, and I hope you will get as much fun out of GB7JB, and the DMR TDMA technology, as I know I will.

Cheers & 73's
Dave, G3ZXX.
