Helicopters and more

portable 2m beam

So having taken a poll and emailed a few people in the know I have set about building a couple of kits from Nuxcom in Germany to theDK7ZB designs.

NUXCOM

I have some of Steve’s special boom spacers and some 8mm pip clips so that I can follow Steve’s method for quick set up.

So far the trial fit looks as if it will work fine.

There is no time to continue today so I will be back…..as someone famous once said.

7000 back on the road

I have put the ic7000 back in the landrover again and this time, without doing anything else, it is pretty much interference free.

I did re wire the Tarheel but that's it.

I have also put the CB back in…but don't drum me out of the brownies…..so i can chat to good buddy MP. who has the same initials as the UKAC site…..just realised that!

I managed to works Russia and a few others whilst broken down the other day o the way back from Kampton Park.

70cms April

Last night was bit of a trial. Conditions were really flat and there was loads of QRM from local stations (I was probably doing the same) although I did get a clean bill of heath on the signal at the end of the contest when we looked at it on a pan adapter with a local station.

Here are some pics from the evening. and it is good to report that the compressor worked well and the mast was ok. Still one section does not work. Now the car engine is making a funny noise…..when will it stop!

Power Draw

With plans of an assault on 1O73 later in the year I had been trying to work out what sort of battery to taks.

Thanks for all who sent in calculations. I had a quick test on the 991 to see what the draw was

New Compressor

Here is the new ViAir compressor from Matt Savage - great service - it arrived in a day

This is to replace the Arb one that was not really up to the task. This is a 100% duty version which hopefully will do the job.

Landy Install

Here is a shot of the 991 in the back to the Landy ready for the 144mhz tomorrow.
The next upgrade is a Green Heron controller.

Stabilisers

Here are the (badly) painted stabilisers to stop the car rocking on its suspension.

And a handy idea, for making sleeves to increase the diameter of tube.

In this case the HexBeam so that it will slot into the rotator on the new mast.

Cut some plastic tube to makeup the difference and split in two.

Mask the gaps and epoxy it into the scaffold tube and leave to dry overnight.

It works! I will need to drill a bolt hole to stop it rotating but that’s it.
