[Hallicrafters] Homebrew Sweep Generator

[Don Ehrlich]

I have just completed a homebrew sweep generator to use in aligning my SX28A.  I had never been successful doing a proper alignment by simply following the instructions in the manual.

The homebrew sweeper uses a pair of 555 timers and miscellaneous other small junkbox parts.  It is a little awkward to use but does the job very nicely.  My old Halli now works like the writing on the panel and knobs say it should.  

Anyone interested can find schematic and info on my webpage at http://www.qsl.net/k7fj  and following the link to the homebrew sweep generator.
