[CQ-Contest] Bandpass filters for M/S or M/M environment

[Zoli Pitman HA1AG]

Hello, 

Dunestar measurements: the first data column is the attenuation to the lower adjacent band in dB. For 15 and 10m the second column is the attenuation to the second lower adjacent band in dB (this case these are more crucial IMO)

80m: -33
40m: -63
20m: -74
15m: -49  -80
10m: -43  -63

I'm curious if anyone has band-to band attenuation values of the NQN. I think its attenuation to the lower adjacent band should be somewhat lower. 

IMO the real goal is to focus to the attenuation to the lower adjacent band assuming that the filter primarily works as an RX filter.

73!
