GB3GD / GB3IM Repeaters

The Isle of Man Repeater Support Group offers whatever assistance is necessary to maintain the islands unique internet linked 70cm repeater GB3IM, and our 2m repeater GB3GD. There is also GB7CA and GB7BR providing connectivity to the DMR network.

Both repeaters are owned and maintained by David Osborn GD4HOZ. He spends a considerable amount of his own time dedicated to improving our radio coverage, and to this end we have a main transmitter on the Department of Home Affair’s mast on Snaefell, one on the top of Carnane on the outskirts of Douglas, and one at Bride just north of Ramsey. These are linked with some very clever software – Allstar, and of course internet. Using the software and internet means that the repeater is available via either Allstar or Echolink over the internet – opening the islands repeater coverage to the world… via a keyboard and PC microphone!

David maintains a separate site for updates on the repeaters: please take the time to pop by and view some of the photos. He also maintains most of the equipment at his own cost… there are limited funds available, and at an average of £500 per antenna for install on Snaefell contributions are always welcome for financial support.

Should you wish to offer your support to the continued improvement to the repeaters, please forward a cheque, money order, etc. to our club treasurer:

Please mark your envelope REPEATER SUPPORT. Altenatively, cash can be accepted by any Committee Member.


This to say a huge “THANK YOU” to all the supporters of the repeaters – whether it be for financial, technical or just muscle power.
