Yet another  ham homebrew site.

144/432Mhz 1Kw/500W Linear build

4x9 mechanical polarisation rotating array

I like building things, it is  the challenges that  hopefully improve my technical skills.

The biggest challenge being to overcome my desire to bodge things

2.4m dish almost finished - just the feed support arms to do. Meanwhile I got distracted by Es'Hail (Oscar 100) and so scrounged a smaller 1m dish, modified a home Satellite LNB and built a 3W up/downcoverter to drive it.

Next plan is to move the Tx feed to the 2.4m dish so I can play with DATV over the satellite.

Still off air.


I decided the semi solid dish was too heavy as with my damaged back and now knee there is no way I could work on it till next year. So I decided to start building my own lightweight 2.4m mesh dish, as I can do that whilst on crutches. Construction details are being added to the Antenna build page when I get time.

Built the 70cm  system - but there seem to be so few stations on 70cm so I decided to move straight to 23cm instead.


I was 3/4 way through building a 2.3m dish, went on holiday, fell and now I'm not going to be able to continue for a couple of months till I'm fit enough to continue working on it.


Since I can't get on the roof to refit the 70cm or 2m system and I took down the Offset dipole for HF, I'm off the air  probably till December!

Due  to the large size of the 2m array and being in a conservaion area - I've taken down the 2m system and now moving to 70cm instead.





An introduction

I'm Richard, a  Software engineer who was trained as an Electronics engineer. As well as my main job I also design and build things for people. Odd things, things you can't buy, things that you wouldn't know where to get made. If someone can convince me it will do some good for someone and it sounds interesting and challenging  I'll have a go at - as long as it covers the costs I'm up for it!

Nothing jumped out at me recently so I decided to try moonbounce - that meant passing the three stages of the radio license which I did in a year, and then start building stuff.

Having built my first 600W linear, I decided that it needed to be rebuilt, bigger and better with the lessons I learnt from the first one

I got a lot of ideas off peoples websites - so this is my payback. I'm publishing what I have learnt and any useful information I found that may help the next person along.

This site is permanently under construction!

My current projects are the linear which I'm still mucking about and altering and my latest antenna project which is a 2.4m dish for 23cm EME.
