[TenTec] Purpose of 250 Hz 8 pole filters

[k8vf_mark@centurytel.net]

If you ever work on a very noisy band looking for weak signals, you'll find 
the 250's-even stacked-help quite a bit.

Also, on most cw contests, the narrow filter really makes a difference in 
blocking out the "neighbors".

Trying to work a station with 3 guys in the 500 Hz passband, is 
futile....but SOMETIMES, the 250 solves the problem.

Dont forget to touch up the PBT as it MAY be different than the 500Hz model.
