[Yaesu] FR-101 AM Filters

[rdavis]

The 6 KHz filter WAS the wide filter for AM.  (I can't recall what was used in the FM board. Maybe 12KHz or perhaps 20KHz?)
INRAD also made 1.8, 2.1, and 2.4 SSB as well as narrow CW filters. 
AM was pretty muffled with 2.4. 
2.1 was useable on SSB, but I never liked the 1.8. Too narrow for me. 
Standard CW filter was 600Hz, INRAD had a 500 and a 250 or 300 Hz which was good for me, but others thought it was too narrow.
