144/432Mhz 1Kw/500W Linear build
4x9 mechanical polarisation rotating array
The biggest challenge being to overcome my desire to bodge things
Update October 2018
Built the 70cm antenna system - but so few stations I decided to move straight to 23cm.
I was 3/4 way through building a 2.3m dish, ( a 1.8m solid dish off ebay and extensions to 2.3m) 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 till probably December!
Status May 2018
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.
The PA parts have arrived to fit the 500W 70cm into the linear box and the H frame is completed as are is the mastheda preamp/switching box and the 4x18 element antennas are very nearly complete.
The good news is that the noise from the shack and nearby houses is much reduced and so I'm looking forward to completing the build and getting back on air.
