Group, This is off topic and I would deeply appreciate any responses to be sent to me off list. I am posting here because I respect the knowledge and experience of the people who are members of this reflector.
This may sound stupid but I have not had experience with this before, so I ask before I do something stupid. I use an external antenna switch mounted on the outside wall of my house to switch in one of six antennas and have a single coax line coming into the radio room. I now have four separate radio stations, 2 K3s and two other radios, all set up differently for different types and modes of operation. All have amps in line that can be used when needed -- one a KW and the others 750w output. Currently I manually attach the output coax for the station I want to use to the coax lead coming into the house from the external switch. A pain. I want to be able to simply use a manual switch to select the station that would connect to the external antenna switch coax lead into the radio room. I would then use the manual antenna switch to select the station and the remote controller to select the antenna. I was looking at the Alpha Delta manual switch with four switched ports and a common and then would connect the common to the coax lead coming from the external antenna switch (DX Engineering) and then each output coax from each of four stations to the four ports on the Alpha Delta and then could switch stations via the Alpha Delta manual switch (all ports not selected go to ground) and, obviously, then select my antennas as I have been doing using my remote antenna switch. Again, this sounds stupid, but I have not had to do this before and always used manual "antenna" switches to simply select antennas. My question is this: Given the Alpha Delta manual switch has >60dB port isolation -- is this isolation good enough that I can use the this manual switch to select stations even though each of the stations has the capability delivering up to 1 KW output? I don't want to blow out the front ends of the radios connected to this manual switch. I appreciate any answers that can be sent on to me. I know this sounds stupid, but I have been a ham since 1958 and simply have not had or needed to do this. I now have four great stations that I carefully put together as part of a "plan" when I retired and I don't want to do something stupid at this point. I have done plenty of stupid things in the past and more will happen, but I thought I could simply ask a question here with hopes someone can allay my fears of using such a switching setup or educate me in those things I don't understand or did not think of. Thanks so very much and 73, Greg K2UM ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
