I don't think the 300 Hz roofing filter would be too narrow for RTTY -
the 170 or 200 Hz shift used in RTTY or Pactor should have no problems
within a 300 Hz 4-pole filter. Remember, sharp skirts are not required
for a roofing filter. I use the 500 Hz 8-pole filter in my Orion I
consistently on RTTY with great results. It's probably close to the
equivalent of the 300 Hz 4-pole, or very close....
