Hi Ray, My group did this once for FD. A few things: 1) You MUST use bandpass filters.2) Make sure that you use radios with good phase noise performance. The year we did this in FD we used three 100W radios through a tri-plexer to a tribander. the radios did not have good phase noise characteristics. On 15 and especially 10M, the radios were unusable on receive. On 10/4/2016 8:03 PM, Ray Day wrote: Hi all,Ray, N6HE here. My radio club plans on going to activate Santa Catalina Island (IOTA NA066) again in February 2017. In the past we've had problems with 2 radios simultaneously on 20/17, 17/15, 20/15, etc. We don't have the room to be completely "tip-to-tip" with our 2 hexes, nor can we get much physical separation between the 2 antennas for the 2 rigs. So - problems.Now I'm thinking that the "Triplexer + Bandpass Filters" idea with only one hex antenna might be the answer. I hear reports that this approach works well, but I'm totally chicken to try 2 of my radios transmitting into one antenna (or more accurately, 1 transmitting and 1 receiving) at the same time. Jeez - 100W that close to a receiver's input???? Nice theory!So my question to the group is "Have you had personal experience with this setup AND does it work as advertised?" I see triplexers from Dunestar and Low Band Systems (with the associated bandpass filters) - we'd be on 2 of 20-17-15-12-10M at the same time.Your thoughts?Thanks in advance, Ray N6HE_______________________________________________ CQ-Contest mailing list CQ-Contest@contesting.com http://lists.contesting.com/mailman/listinfo/cq-contest -- 73, Gary K9GS Greater Milwaukee DX Association: http://www.gmdxa.org Society of Midwest Contesters: http://www.w9smc.com CW Ops #1032 http://www.cwops.org ************************************************ _______________________________________________ CQ-Contest mailing list CQ-Contest@contesting.com http://lists.contesting.com/mailman/listinfo/cq-contest |
