After around five years of trying to get a set of working duplexers for GB7IV, a brand new set has been successfully obtained privately.
This gives us the desired opportunity to run a digital repeater on VHF. Once our engineers can get access to the repeater site, due to COVID restrictions, We will take one of the spare FM GB3SH repeaters and set it up as GB7IV on the GB7IV channel of R7:- 145.775MHz, and basically see if we can get two repeaters to function on one site without problems!

We will need your help with this experiment.
The experiment will use the aerials which we intend to use, as they are already fitted!
We Will of course let you know as to when We will run these tests, as those tests can only go on for a few hours at best, due to licensing, and We will want QSOs to go through both the repeaters at the same time!

You will not need special equipment, for these tests, just a FM transceiver on either the usual GB3SH channel, or a transceiver on 145.775MHz FM, the old GB3PC channel with CTCSS on 71.9 Hz. on transmit.

GB7IV will have CWID with the callsign GB7IV for legal reasons, and your interest, as normally of course GB7 callsigns are only assigned to the digital service. If you would like to help with the purchase of these filters please contact: on info on how to help with this privately funded project.

In addition We are pleased to announce that Richard G4WFR, the keeper of GB7SU and his digital DMR repeater station, which was close to Southampton docks, has joined the SHRG with his repeater:- GB7SU which is currently in West Southampton. The opportunity will be taken, to test to find out how we can successfully run the DMR repeater on our site! Once again We have the capacity aerial wise, and duplexer / filter wise, to run GB7SU from our repeater site hopefully, without interference with a much improved coverage for the DMR users.

We will on our link pages put information on how you too can get operational on DMR, the kit to use, where to get equipment from, and to avoid how to get the radio programmed,and how to obtain the needed
"Digital ID" for which a pdf of your Amateur licence is required

In the meantime keep a watch on this site for more information

17/01/2021 Amateur Radio history story from the BBC


We are pleased to announce that our GB3SU & GB7MT Broadcastify links are back on and connected up. The GB3SU link has been back on for around 6 days.
They were moved due the pending loss of the needed internet connection at their previous location. The new location is in a high signal area, hopefully this will improve the recovered audio especially on GB3SU, and reduce the QRM on 70cM.

Changes will be made to the aerials used over the next few days, which may interrupt the service for a while esp on GB3SU. Reports are welcome, esp on audio quality which we know is not BBC radio 4 quality to:



The weather station returned online today at 16:00. The Weather Cam is still off line and should return in the next 24 hours



Update: An engineer is on the way today to fix problem in West Southampton

We have lost our Video camera and Weather feed thanks to a fault on internet provider network which occurred at 1101AM on Monday 28th of December, which affected the Millbrook, Maybush and Shirley areas of Southampton.

While the fault in the network has been cleared, it has the effect of this has knocked out our connection to the internet. This fault is a variation on a theme on around 50% of the reason's as to why we lose connection, some of the faults are to do with the linking equipment, all of this as such is is all out of our control. Due to the COVID restrictions We can't go to our site to make our standby alternative arrangements work - frustratingly.

Unfortunately as this is late December, and many are on leave, We seem to have little hope of any any improvement and a return to service of the weather station or a viewable camera until Monday the 4th or later on in the week. However We are pleased to say our internet free link to GB7PO works fine, and this is the reason why we dont use the internet for this link!
