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.
