[Elecraft] 700 Hz roofing filters

[Wayne Burdick]

700 Hz is a useful CW/DATA filter bandwidth, certainly. I'm not  
surprised that some K3 owners are interested in this.

Personally, I prefer much narrow CW/DATA bandwidths, and I use all  
modes. The lineup I use (and generally recommend) is:

FL1   13 kHz (FM)
FL2   6 kHz (AM/ESSB)
FL3   2.7 or 2.8 kHz (SSB and casual CW/DATA tuning)
FL4   400 or 500 Hz (normal CW/DATA)
FL5   200 Hz (CW/DATA in heavy QRM)

73,
