Comments Off on RSGB VHF Contest Committee Consultation for 2020 Rules

Once again, the RSGB VHF Contest Committee would appreciate your views on a number of topics to help us set the contest rules for 2020. The survey is quite short because we are not considering major alterations to the rules for next year, but all your views are read and appreciated.

The survey will close at midnight on Sunday 10th November and is available at

Thank you for taking the time to complete this survey.

GB3TD Frequency Regression

Comments Off on GB3TD Frequency Regression

It is with regret that the GB3TD repeater will be returned to its original frequency configuration 433.075/434.675MHz during the afternoon of Wednesday 30th Oct.

The RRG apologise to those that have already reprogrammed their radios however this regression is required to overcome some issues that have been experienced over the previous week.

This will be a short term fix whilst we discuss options with the Repeater Management Committee.

GB3TD Frequency Change from 18th Oct 2019 – Action Required

Comments Off on GB3TD Frequency Change from 18th Oct 2019 – Action Required

The Swindon UHF repeater GB3TD has been operational on the same frequency 433.075 MHz and from the same site since 1994 and is managed by the Ridgeway Repeater Group.

In recent years the repeater has been suffering from interference in the form of clicking and pulsing noises and also from wideband transmissions which can severely desense incoming signals.

The group has spent many hours trying to determine the source of some of these without success.

OFCOM were consulted and tried their best to identify the problem without actually finding it due to restrictions gaining access to certain areas of private property.

The main interference to our secondary use band is from 433MHz to 435MHz which emanates from low power devices but also the MOD which is the primary user of the band.

When GB7TC our DMR repeater was commissioned and co-sited with GB3TD and using the same antenna, the filtering system was complicated and caused extra losses in the system. Never the less has worked well.

A question was asked to the RSGB repeater committee asking if a 7.6MHz wide band split would be possible for GB3TD.

The RRG were asked if the group would like to try a reverse shift to the normal TX-low, RX-high configuration.

GB3TD output frequency will be 438.4375 and the TD receive will be 430.8375.

This was agreed upon and an NOV issued to Rob, G4XUT.

The benefit is that the filtering for GB3TD and GB7TC will be easier with less through losses with both TX and RX being at the same ends of the band.

On Thursday 24th October, Andrew (M1CJE),  Dom (2E0WHQ) and possibly others will be helping out anyone who is having problems re-tune or re-program your handheld, mobile or base station radios. They will be providing a couple of laptops running CHIRP (the popular radio programming software), a selection of programming leads and assistance to get your radios up and running on the new frequencies. A dummy load, frequency counter, with CTCSS checking will also be available so that the new configuration can be checked. Additionally, a 13.8v PSU will be available for mobile radios.

If you are interested in getting your radio re-programmed or just want to learn how to do it, then please come along and bring your radio with you. We should have the facilities to cater for most of the popular brands and models of radio including Baofeng, Wouxon, QTY (and clones), Yaesu, Kenwood & ICOM.
