DSB Transceiver with Only 3 Transistors


Wow.  Looks like something Peter Parker would really like.  This one was sent to me by Stephen, G7VFY.  It comes from Japan:

"That 70s Show": Steve "Snort Rosin" Smith Restores a 70's era Tuna Tin 2




Hi Bill,

Your recent stories about your TT-2 and original TT-2 "mojo transfer" prompted me to resurrect my TT-2 'resto' project. 

The attached photos show my 70s era TT-2 obtained for $5 from a QRP-L member.  This is how I received it and you can see that it's almost a duplicate copy of the original, complete with 'phenolic' substrate PC board material and hand-scrawled traces. 

I have collected most of the components necessary to convert it to a look-alike of Doug Demaw's 1976 item.  I already have 1 or 2 of the proper Radio Shack RF chokes but lack one more to have the complete set and I'm about to grab some original Radio Shack 276-1617 transistors.  The rest of the missing/incorrect parts I can drag out of the ever expansive Snort Rosin junque box. 

By hand selecting the two transistors for max. power gain I hope to eek 300 mW out of the thing.

Anyway, hope you enjoy the shots and I'll send more when it's finished.

73.......Steve Smith WB6TNL

This morning I got a nice e-mail from Pete.  He's been listening to the podcast.

His e-mail caused me to revisit his web site.  Lots of minimalist homebrew gold there!

Check out the collection of projects sent to Pete from all around the world by readers of his books:
