GB3IM began life as a co-habitant with GB3GD on the summit of Snaefell.

Following a protracted period of downtime caused by antenna failures, the group decided to look at options to keeping the island connected but which did not rely upon Snaefell.

The result was a project to set-up and internet link three repeaters in strategic locations on the island. All three repeaters are controlled and linked using the AllStar Link software, masterminded by the late Jim Dixon, WB6NIL.

The AllStar software also provides us with an EchoLink gateway, giving us the best of both worlds.

We do not have (and never will have) any facility to interface with IRLP.

The Notice of Variation for these repeaters was first issued on 26th March 2008.


GB3IM-S Snaefell is our key site, filling-in many local grey areas and also giving coverage of the coastline of the surrounding countries (England, Ireland, Scotland and Wales).
GB3IM-R Located in the North of the island, this site gives coverage in areas inaccessible to Snaefell, particularly the section of the T.T. course between Sulby and Ramsey.
GB3IM-C Just to the south of Douglas is Carnane, a hilltop with a great view to the south and west. This location gives coverage to many areas that are not well served by Snaefell. It also serves as an important backstop in the event of Snaefell's repeaters being unavailable.
GB3IM-P This repeater is located on the roof of Peel Power Station, adjacent to the top end of Peel Harbour. Good coverage is available along the west coast road to the north of Peel as well as towards Glen Maye to the south.

It is recommended that users connecting from outside the network should connect to 2480.

Polite request to remote users:

When you make a connection to our node it triggers a voice announcement of your presence. Since we know you're there, please be good enough to listen for a while and also, since you've joined us, why not make a call?

It takes a few seconds for the announcement to complete, about as long as you would normally wait before joining any other QSO so please - listen on the channel for at least 15 seconds before making a call. If you don't your call will compete with the voice announcement, and you will probably lose!
