[CQ-Contest] Need confidence....

[Trent Sampson]

Hi Ray 
I have the Dunestar 600s  with both variations of the Dunestar triplexer - 
The first of the 160 80 40 Model and the 20 15 10 version. 
Using 100-watt radios I can run SO2R off a single antenna with negligible band noise. (it is there if you look for it) Less than s1 in real world terms, usually hidden by local band noise. 
Mine runs FT2000 or FT950 >>>Dunestar 600 >>> Six pack  >>> Triplexers >>> Stack Match>>> Antenna combinations
Bear in mind they are only rated at 300 watts or there about so if you are using more than 2 rigs in a multi-op environment you may well pop something.
When I put the shack back together I will measure the noise on the whole system and give you some figures.
