Wow, Dean's BITX with Termination Insensitive Amplifiers (3 of them) sounds really nice. And this is with a homebrew ladder filter (see below).
I also like the way Dean makes his enclosures -- he uses scrap aluminum and 1/2" angle. This might cause me to abandon the wooden cigar boxes.
Dean will now add the driver and PA stages and plans on following Pete's suggestion by making this a 20/40 rig.

Bill,
ReplyDeleteAfter several weeks of work on the enclosure, I would not recommend building an enclosure this way. Takes too long.
I absolutely know Deans' radio is Digital --it has a nice square hole on the front panel. Beautiful craftsmanship and it sounds Awesome!

Awesome,
ReplyDeleteThinking of building one, specially after this crystal ladder, Can u give me some details on impedance transformation? Is there any easy way to find the impedance of a crystal ladder ? Also is it ok if I replace the SBL-1 mixer with the DBM made up of Diodes and trifilar inductor like one in BITX20?
Thanks
