[Trent Sampson]

I was also curious about the techniques used at PJ2G and was pointed in the direction of this product.

The manual shows lots of examples of how they are installed and used

Subject: [CQ-Contest] SSB & CW On Same Band

Has anyone successfully run 2 stations on same band, SSB &CW, without interference between the two? For example, FD or IARU.

We have tried it several times and have always ended up with moderate to severe interference to the point that one  station had to qsy to another band.

Obviously (I think) the filters that are in common use like Dune Star, ICE, NQN, etc. don't work because they are band pass filters. But has anyone designed/built a filter with sharp enough roll-off to make this work?
Or, would a pair of K-3's , etc. fit the bill?

Would love to hear from people that have made this work for them, and how they did it.
