Audio Filter

[Fred e holnagel]

Those of you familiar with the FL-8 or FL-5 audio filter will know what
this does.  It is neither of those but does the same thing.  Sharp cut
off 1020 cycle filter very effectively cuts that freq. off.  An
interfering CW signal is tuned to 1020cy. where it suddenly disappears!
This one is easy to install inside most radios in series with the phone
jack.  Only 2" square by 1.25 " deep with solder lugs. UTC range filter #
JL-986.  $20 shipped.
This ad appears on Heath reflector as well as B/A as it would go well
with many HW/SB radios.
