KC1FSZ's Above Board, Al Fresco, Free Range, QRO, 4-Foot-Long, Wood-Based BITX


DON'T BOX IT UP BRUCE!  LET THAT RIG LIVE FREE AND BREATHE!  

COULD THIS BE THE WORLD'S BIGGEST BITX?

Hi Guys:

First off, congrats on back-to-back SPRAT covers.  

I’ve succeeded in my QRO quest.  Now I’m running the finals from 28V using a home-brew linear power supply and getting about 20W out.  LM723 + 2N3055’s.  I’m making a lot more contacts too.  The only problem is that the “Peppermint Line” is close to 4 feet long now! (Photo below).  I don’t know how N6QW gets his rigs packed into such small cases.  Putting the various boards in edge-wise will probably help a lot, so that’s going to be my approach to the final packaging job.

73s, 

Bruce KC1FSZ
