UNUN Notes - Double Core FT140-43 & 2t Primary
Ready? Well, alright fellas- let's Gooooooo!
Thump in beginning. Darn phone! What to do: upload as-is or wait for the transcoding, which is about 8 hours? Guess I’m going with the thump. It’s my ‘style’. Lol.
This is a new UNUN: double core FT140-43 using only 2 turns on the primary.. and a total of 18 secondary turns. Will it work as good as the 3-turn primary on 80m (a UNUN’s most challenging band)? I’ll find out and share the results with you.
I forgot to show the math. The math showing why I think this could work out OK. I’ll show that in short vid if there’s any interest. You can have a copy of the spread sheets if you like.
