Good day I am putting together a Vectronics 80 Meter Transceiver Kit
, the problem I have is winding the T50-2 toroid , the instructions
state to wind 40 turns of 24 gauge wire, would that be two passes of
twenty as forty on a single pass is nigh impossible. Help would be
appreciated.

Bad Instructions! You can't get 40 turns of 24 on a T50 core in a single
layer. Go to #26 or even 28. It won't change the inductance appreciably for
the same number of turns, and you can space it properly. Given just the
number of turns, you probably won't be within 10 percent of the desired
inductance anyway.
