[Boatanchors] FL-5-F

[Al Klase]

Mac,

I believe your thinking about the FL-8.  The FL-5F is a stand alone 
filter that is used with the BC-354 selector switch to achieve the same 
function as the FL-8.

SEE:  http://aafradio.org/flightdeck/BC-213.htm

In either case the filter is used to either select or block the 1020 Hz 
Morse signal used on the old A-N Navigational Ranges.  Some of these 
stations transmitted voice data, weather etc., as well as the 1020 Hz 
A-N signals.
