I have gotten back into SWL'ing lately ... (ain't like it used to be
either!)

Got a couple of old Hallicrafter receiver rigs and replaced the front
end tubes with some GaAs semi circuits, done on a pcb board and serves
as a direct replacement for the tubes--except for the need of filament
current, they are "work-a-likes" ... gawd, bet those old boys wish they
would've have had those when they engineered the rigs ... I just love
the look of these old "solid" rigs! (solid as in "weighs a ton!)

I am interested in anyone else who has "tweaked" old rigs with various
"kludges" and gotten good results? Comments? Advise? Construction?
Results? Ideas? Unique construction? Anything? ...

Now, this post might NOT be "right on topic" for antennas, but darn
close, we DO have to consider what our antennas feed, right?

Warm regards,
JS
