QDX build help - weird twisted sister


 

Hello,
?
I was very proud of my 3:3 weird twisted sister when I made it yesterday.
?
Today I realised I used the #28 wire and I should have used the #22 wire.
?
Will I need to desolder and remake it, or will the #22 wire be OK?
?
thanks

Hi Rich

All future?kits will be supplied, once current kit batches are exhausted, with only #28 wire (0.33mm). This is because I tested very carefully including power output, efficiency, harmonic content and the thinner wire works just as well in the output transformers (and QMX SWR bridge, and FT37-43 choke) as the thicker 0.60mm (#22). In fact if anything, the #28 wire works slightly better, probably due to it being easier to attain better symmetry. It's also easier to solder (burn off the enamel) and will make our kitting job easier as it's all then only one wire type.?
