Whilst many of the more experienced amateurs can design complex circuits, manufacture printed circuit boards and build a chassis or enclosure, a good way for the beginner to start construction is with a kit.


This page gives links to product manufacturers, both in the UK and overseas, whose products members have actually built, have contemplated building or use.



RATS Coax etc           Cables and Connectors and power cables.


Kent Engineering         Morse keys, paddles, keyers etc.

Elecraft K3  Report of used example purchase and upgrade


W2AEW  Over 200 youtube videos explaining many aspects of Amateur Radio and electronics.  Most of the projects that I have tried actually work!  eg search for #88 Time Domain Reflectometer for an excellent project and # 37 which explains how to use it.


Rotator Service.  The Valvoline grease recommended for Yaesu rotators is not available in the UK as far I can determine.  I have ample “Z030K10_TDS Z030 Fifth Wheel Grease.pdf” which is an equivalent and is available to all at £1 for 50gm (enough to service at least two rotators).   Once those steel balls running on diecast aluminium start to corrode, rotator life becomes limited.  The grease needs to have some degree of water resistance, since the bearings are not sealed.  Suggest wearing nitrile gloves - it doesn’t come off easily!  Yaesu UK on 01962-866667 can supply parts.  If you are having trouble with your rotator, I might be able to help, having successfully repaired an old G1000DXC after downloading instructions from the internet and more recently a G400RC controller with a cracked PCB, broken tracks and an open-circuit miniature inductor.
