Some of the relay-based antenna switches actually have two sets of relay contacts between the antenna and the not-selected radio. This can improve the isolation.
However the difference between "S9+" and "I can barely hear" is a whole lot of dB, and asking for complete silence is asking for a lot. http://www.qth.com/topten/abss.htm Dick, K6KR -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Bennett Sent: Tuesday, December 31, 2013 12:56 PM To: Elecraft Reflector Reflector Subject: Re: [Elecraft] KX3 / K3 Antenna Sharing Thanks for the info all - I looked at that Bird 6 position switch - about 1/2 the cost of my KX3 - yikes! Think I'll pass on that one. I do have a Daiwa 2 position switch that I've hooked up to share my antenna - one side to the K3, the other to the KX3. Seems to work OK, although when a strong signal (S9+) on the K3, I can still hear it when the switch is set to the KX3. I wonder if the Alpha/Delta switches have any better isolation that thiat Jim / W6JHB On Tuesday, Dec 31, 2013, at Tuesday, 12:38 PM, Edward R Cole wrote: > I am using a couple DAIWA manual coax switches. 2-pos selects either K3/10 or KX3 (at 12w) and 4-pos is for antenna selection at 300w from the amplifier.
