How to build an antenna switch
the bands are full of competitions today so I gave up after a few seconds.
not my thing at all.
so, as I'm planning a second antenna, a Windom off centre fed dipole, to get 80m and improve 40, I'm going to need a switch, right?
so after extensive research......
OK, I asked on the QRZ.com Homebrew & kit projects forum....
http://forums.qrz.com/showthread.php?371010-can-I-use-mains-light-switches-for-coax-switch
so, those smart folks say that it's OK to use a mains light switch to direct the RF.....
so, first I need a metal case.....
it's been on top of the kitchen cabinet for a year, so it won't be missed by my very understanding XYL
mark it out.....
and drill a few holes.....
a dremel tidies the holes and the used sockets I got off ebay are attached...
then the switch....
its a 3 gang 2 way switch.....
so I reckon I can feed one line in, then the first gang directs the signal to one or the other of the remaining switches, giving 4 outputs.;.....
so, from the input socket to switch 1 then from the 4 outputs of switch 2 & 3 to the 4 sockets on the lid..... I know the metal case should carry the ground, but I put a wire on as belt & braces..... (no flash... sorry!)
then, all assembled and testing for continuity......
so now that I know it switches as I had intended, I can mark on the switches so I know what goes where.....
and a rear view for the input
as Master Yoda would say..... pleased with this I am!!
Now to get the antenna sorted!!

So, summing up 2 months on HF.......
Bands:
10m 5
15m 1
20m 633
40m 21
modes
SSB 580
CW 81
countries.....
these from eQSLs list.... don't complain and say that the Azores count as Portugal, OK??
Also, only folks registered with eQSL count for the countries worked certificates.....
and I've had a few SWL reports too, so they throw the numbers out a little too!
so that's 40 then......
10 US states:
Coneticut
Delaware
Illinois
Massachusetts
New Hampshire
New Jersey
New York
Ohio
Pensilvania
Vermont
and the distance top 20?
