GB3GY Is Grimsby’s 70cms voice repeater which operates on 433.275mhz

access by either 1750hz tone or CTCSS 88.5hz, I switched it on 17 June 1981 and G2DXB called me for the first official contact, it had been used prior to that for test purposes.

Also in Grimsby we have a TV repeater GB3GG

The repeater is owned and run by the Grimsby Amateur Radio Society,  as clubs cannot hold NOV's for repeaters John G0ATW has kindly offered to be the registered Keeper QTH taking over from Brian G4DXB who had been involved with the repeater from the beginning the Club wishes to thank him from all his hard work.

 Latest Repeater report.

M S Distribution has recently (Sept 2013) donated a wireless link equipment to link Nelson House with Thesiger House; this is so Richard’s company can supply the repeaters with free Internet access


After a few months organizing a work permit  with specific risk assessment and method statement work took place on Saturday 18/09/10 to service the aerials on the roof top at Thesiger House.

Clamps and poles were replaced, feeders tidied up, aerials straightened and GB3GGs TX aerial replaced.

In total Lee G4TNX and John G0ATW worked for 6 hours on the roof!

First signal strength reports for the new GB3GG TX aerial look very good.

Unfortunately the planned TV link to Lincoln failed due to a faulty coax feeder maybe this will happen on next years maintenance visit.


One problem is the transmit filter on GB3GG it is about to go away for re-alignment.

The effect of not having the filter is causing the receiver to see the transmitted picture producing feedback.

To prevent this becoming a problem I have switched the 13cms receive off temporally, it will be on Friday night and by request.

This does not prevent access on 23cms or 10Ghz, reduce the transmit signal or effect the web stream.


Note the replacement PC, solid state hard drive, replacement PA and hours of labour have all been funded by the ATV group.


If you hear abuse please contact John by email


I have spent a lot of time monitoring GB3GY lately and heard no problems

 but also very little activity.

It would be a shame if an attempt at increasing activity with the Echolink NOV is spoilt by abuse.
