RSGBTech is an independently-run group. It aims to provide technical help and discussion of amateur radio related technical matters, and currently has around 1,500 members from a range of different interests within amateur radio and around the world. It is a useful source of independent discussion of technical matters raised in RSGB publications, periodicals, website and other communications channels.

If you have just started in amateur radio, can you use it?
Yes, of course! RSGBTech is meant for everyone, the newcomer and the old hand alike. The biggest asset to the hobby is radio amateurs themselves. There is a wide range of backgrounds, knowledge and experience on the site. Even if you require advice on setting up a station for the first time, need to get to the next stage of the licence or want to source that special component which you have not been able to find for ages then RSGBTech could be the place for you. There is always someone willing to advise.

Is the site moderated?
Yes, but to ensure that the questions are on topic.  For example they have to be technical and related to amateur radio, and that the general guidelines for RSGB on-line facilities are being observed.

What else you can do on the site?
You can post photographs, files, drawings etc, but please ensure that they are not subject to copyright. If they are, then please ask permission from the person who owns the copyright in the first instance.

How to join the site
Simply go to and click the “+ Apply For Membership in This Group” button and follow the instructions. The whole process only takes a few minutes.

Sending a technical query
Once you have set up your membership, simply click on ‘New Topic‘, type in the subject details and your technical query. Finally, click on the box that says ‘send’. Your message may take a little while before it appears on the site, as it is now in the process of being moderated. You may get a few replies or lots! It may indeed start a flurry of activity and interest from around the globe on a particular topic that keeps the moderators very busy!


This Yahoo group has been running since the mid-1990s to support technical and operational matters on frequencies below 160m such as the 136 and 479 kHz bands.  It is open to all Radio Amateurs

IARU Matters

The RSGB IARU forums use newer facilities and replaced the older UKC4 and UKC5 Discussion Yahoo Groups. These  facilitate consultations and discussion by UK Amateurs of papers submitted to IARU Region 1 Interim Meetings and General Conferences. Sub-fora cover C3 (General matters), C4 (HF matters) , C5 (VHF/Microwave matters) and C7 (EMC  Matters).
