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.
Got wet <30mins after putting up and was simply hopeless trying to get it to work with water in the poly caps and the switch. Definitely needs a cover BEFORE putting up if going to be wet.
