QRPGuys 80/60m Vertical Antenna
This will be used on 80m QRP as M1K in the RSGB IOTA contest 2018 from EU011 St Agnes.
It is going to basically be a centre loaded GP on 80m.
The last contest on 80m was from C6 and from there I had two full sized phased 80m verticals. Wanted to work loads of G stations, this time I'm 4000 miles closer so this should do fine :-)
Of course I know from St Agnes looking West I have nothing but salt water path to NA.
Propagation might be metaphorically in the toilet but I suspect a contest will test that hypothesis.
Anyway as the build goes on I will add to this post. As per the 40m-10m UnUn there are no antenna wires, I'll add this a bit later as that will need me to get the poles out etc.
All the parts laid out before start.
Not got any more photos from the build..
Also have a 1:1 and 1:4 balun so will make those up too.
Had to add some M6 screw and nut hardware on the 4:1 as the ones I had failed. My mistake tightened the bolt too much.

M1K RSGB IOTA 2018 from St Agnes EU011
The antennas will be approximately where I marked on those images.
This time with a few extra challenges.
Rig will be ATS-3B (Designed by KD1JV)
Antennas will be from QRPGUYS for 80m I'll use the 80/60m Vertical Antenna and for 40/20/15 & 10m I'll used the 40m-10m UnUn Plus
I will also take the QRPLABS Hans Summers, G0UPL designed QCX https://qrp-labs.com/qcx.html on 30m and a SOTA Beams WSPRLite https://www.sotabeams.co.uk/wsprlite-antenna-tester/ (also on 30m) and will be qrv before the contest as M1KTA and the WSPRlite will be on during the contest.
I found the tiny new Mini USB Keyer from K1EL a must have for contesting with Win-Test as used so well as C6AKT earlier this year in BERU/RSGB Commonwealth Contest (won the Lilliput trophey for winning the QRP category) http://k1el.tripod.com/WKmini.html in UK you'll find KANGAUK have it available. https://www.kanga-products.co.uk/k1elsystemproducts-winkeyer
Got a nice shack too, I had operated from an old shed on exact same location in 2016.

One of the antennas for RSGB IOTA Contest as M1K from St Agnes EU011.
The current build docs are here https://qrpguys.com/wp-content/uploads/2018/05/unun_plus_assy_051918.pdf
My build... will update as it goes.
Layout all the parts and check with the circuit diagram.
I can see I have a spare capactor indicator plate but a missing 470ohm resistor. No harm got one in the 'junkbox'
Why do some find some torroids so hard to wind?
The FT37-43 SWR indicator torroid is not hard.
Watch the orientation of the zip ties as you pass them through the board if you want them to sit flat.
C1 & C2 yes you have to modify, not hard just be really careful taking off the plastic. I use a little bench vice and hacksaw and just cut a couple of slots.
T1. I changed the provided tie wraps for green and orange ones but the provided ones are fine.
T2. again I changes the provided tie wraps for blue and yellow ones
There the kit ends so will have to add wires etc...
I suspect if gets wet might be fun so will craft a cover of sorts.
