New 6m beam for the UKAC

6M Beam

I have been chatting with my pal Terry about what to do for the 6m UKAC next year (when the Nordic scoring system has been sensibly been adopted) and my thoughts turned to making a more portable solution to my 5 ele LFA. More portable in the sense of the time it takes to put it together.

So taking clues from the 2M ones that I have made and written about before I am going to have a go at a 6 or 7 ele DK7ZB version. So the question was to make some stronger spacers that the elements can clip into. Cue the new 3D printer.

I started with the driven element box which is going to be something like this with a core built in to wind a choke on.

And for a first attempt it turned out pretty well

I will probably have a go at printing a bit to hold the driven elements in as well.

This is the idea for the other passive element clamps which will have a 10mm pipe clamp on the top

Time Off

Sorry for the delay on posting. I’ve been away to hospital for a bit of an op.

Now home and awaiting a very special package to arrive from Larry in the US. That is going to mean that I need to re-do the shack somewhat so I thought I would post a current picture of where we are at the moment.

More to follow when the LP-700 arrives. See you then

Shhhhh.

Charlie has brought me a WSPRlite from Sotabeams

Apart from having to find one of those old fashioned Windoze computers to set it up, it is a breeze and works a treat.

I am sending 200mW up my delta loop at the moment and in a day have been spotted in all these locations

This is a really useful tool. Check it out.

New Aerials

Are up and look as if they are working now - despite having to put the scaffold up again to sort out the connector on the pre amp.

Changing the Beams

Here we are on a cold winters day in the rain up the scaffold swapping the 2m beam for a DK7ZB 10 ele and adding on a Dual antennas 14 ele 70cms. With with pre amps.

Looks like the 70cms is k by the B*** connectors on the 2M and doing this usual not quite making is so the scaffold needs to go up again.

Thanks to SUR for coming round and helping. It makes all the difference.
