Repeater Hardware, Funds & Talks

Hi All,


The Motorola DR3000 Repeater unit has now been ordered.

Still aiming to get GB7JB on air by the end of this month.

Although, as you can see, not all the pledged donations are in yet, 4 to go, I have gone ahead and ordered the unit on the assumption that the remaining pledges will be honoured in the not too distant future.


We have now received £1,530 of the £1,600 of pledged donations, from 35 of the 39 individuals who made pledges.

Make your donations payable to:

If you don't select either the "friends and family" or "Donation" option, we have to pay a quite significant fee, and thus ​we ​do not get your full donation, as has happened in a couple of cases.

As per earlier e-mails, if you wish to pay by cheque, please send your donation to:

GB7JB Repeater.
c/o Mr. P. Hillman, M0ACD

BA8 0JH.

The following is very important, for donations by cheque.

Please ensure that your cheque is made payable to “GB3JB Repeater”. That's GB3JB Repeater”.

Also ensure that your NameCallsign and e-mail address and that it is a donation for GB7JB are all very clearly printed on the reverse of your cheque.

An acknowledgement of your donation will be sent to you via e-mail.

Do NOT send cash under any circumstances.

​Talks / Presentations.

This weeks two events, at the Andover and Trowbridge Clubs, were very well received, with much interest and support being offered by those present.

The demonstration of the equipment / technology, which involved the use of 4 different radios from different manufacturers, went down very well indeed, and dispelled many individuals concerns about audio reproduction and quality.

I personally enjoyed the events, and thank the Clubs for the opportunity outline the project, and clarify / answer the many questions and issues raised by their members, regarding the technology, as well as GB7JB and the Regional Cluster/Network.

I must thank the two clubs for the hospitality shown to me, and the very positive outcomes from the evenings.

I have been asked to do the talk / presentation for the RSGB (Bristol Group), and this will take place on Monday 27th April.

There is also the possibility of giving the talk / presentation at the Taunton Club.

If any other groups or clubs would like the me to come along, then send me an e-mail.  I will be only too pleased to oblige.
Cheers & 73's
Dave, G3ZXX.
