For Sale Audio Fitler

Fri Aug 8 11:57:43 EDT 2008

Hot item for sale. You older guys will remember this item. It's the Army Filter FL-5-F.  A sharp skirted audio cutoff at 1020cy.  Great for CW, tune the interferring signal to 1020 cy, and it will disappear. It was to attenuate the voice transmissions on the aircraft radio range signals.  Install in series with your phones or speaker.  About 3.5" cube in size in cast aluminum case.  $12.50 plus shipping..  Fred W7PRV
