[Elecraft] 700 Hz roofing filters

[Ken Chandler]

I'm a 99% cw op, mine are 2.7 (soon 2.8) 2.1, 500, 400, 200. Sub is 2.7, 500.
The 400 I use always for contesting.

Doing CQ WW RTTY as a low power multi single, this weekend as first time ever on this mode have WinTest es mmtty es setup for AFSK A.

What is the preferred filter width min es max in these crowded bands.
Hopefully the P3 will give me an edge squeezing in somewhere.
