One thing I forgot to mention: In Olivier F5LVG's DC receiver article back in SPRAT 100, he casually mentioned building a transformer for his mixer by taking two inductors of the appropriate values and GLUING THEM TOGETHER. What a great idea! I had to try it. I did. Picture above. It worked in my Ceramic DC receiver, but the trifilar transformer from Farhan in India worked better. Perhaps the coupling was tighter. But hey, it worked. Three cheers for Olivier.

Thanks, Dan, for the excellent pictures. It was great meeting you for the
first time, as well as a few other notable first-time-meets including Joe,
W3GM...
