SV: Topband: SSB on CW segment

[Lars Harlin]

Mauri,

I'm not sure I follow you here. What  are you trying to prove?
In principle you are right though, regarding phase noise, clicks etc. and I can agree that 40 CW stations at a segment of 10kHz in a contest situation is a bit theoretical. Not to the extreme though, as its quite possible to have even narrower filters for CW... 

However, in a contest situation, many SSB stations wont fit into 10 kHz alone! So I guess that the 40:3 ratio applies anyway...

My point is that as log as we dont have the same bandsegments on 160 WW,  and some countries a small bandsegment of 50kHz total, it will be very difficult to keep the CW/DX portion of 160m free from phone traffic during SSB contests. Thats why I consider 160m a NO-SSB-CONTEST band!
