[Milsurplus] Narrow AM mech filter ?

[Bill Cromwell]

Hi Dennis,

2 kc bandwidth is usually an "SSB" bandwidth but we can recover one 
sideband of AM voice through one of those. Yes..it is getting "muffled" 
a little but is usable. The receive VFO would be tuned so that it falls 
just at the edge of the passband or..we can use "exhaulted carrier" by 
using the SSB BFO to substitute or compliment a diminished carrier. If 
there is adjacent channel interference on one sideband we can switch to 
the other sideband to get rid of it - perhaps to find interference from 
a different station <evil grin>. This approach is not good for listening 
to hi-fi music. I abuse my "SSB" receivers this way sometimes.

73,
