New stackbox

Ham radioPosted by Mikael Larsmark 2007-11-21 18:16
I'll be receiving some russian vacuum relays soon that I thought I'd make a new high power stackbox for my future 20M stack. I still need to find some 7/16" connectors but hopefully that will not be too hard to get hold of, I also need a good box to build it in that is weather proofed.

I designed it so that these combinations are allowed:
--------------------------------------------------------------------
ALL
TOP/MID
MID/BOT
ALL, TOP/MID/BOT*
ALL, TOP/MID*/BOT
ALL,TOP/MID*/BOT*
TOP/MID, TOP/MID*
MID/BOT, MID/BOT*

Where the * indicates that the antenna has been put 180 degrees out of phase. This is to be able to steer the take off angle of the stack a bit more, since sometimes signals come in from pretty high angles, especially during solar peaks. I will need to simulate a bit in the future and see which combinations are useful to implement in the control box.

Here is a schematic of how I will build the box:

The search for a QTH Part 1

Ham radioPosted by Mikael Larsmark 2007-11-08 09:26
I am looking for a place to buy where I can put up all the stuff I have bought. I have gathered some equipment through the years and recently I bought SM2HWG big tower with antennas so now I'm pretty stacked with stuff.

The search after a QTH will begin for real when my job hires (if they do...) me for real but I have still been peaking at some places. You can get hold of like summer cottages pretty cheap up here, everything between 10 000 euro to 32 000 euro is what I feel reasonable, if it's gonna be for radio use only.

If I manage to find a QTH close enough to work so that I can live there, then of course it can be more expensive. First thing I'd do if I find a QTH? Put up a 4 SQ for 80M and a vert for 160M smiley

Here is one object I found...

It's not too much land, only ~10 000m2 but maybe that can be bought more of it or get to borrow from the farmer who owns the fields.
