I am building the Small Wonders psk31 20M transceiver. I wound 4 torroids. t37 and ft50 sized.
There really is a difference in magnet wire coatings. The wire supplied by small wonder did not tin by dipping. But what I picked up at the electronics store did.
I dipped the tips in some flux and then into the solder pot for a few seconds and out came nice shiny tips.
Now, I do not know if they work. There are no diagnostic and setup steps until everything is put together.
