A few days ago AC0LP suggested a mini-module kit for the purpose of sharing the coax with 12V control line(s) - an enhanced bias T, essentially. N1AL followed up with a nifty design he had used for selecting up to four remote antennas without running additional conductors - Thanks Alan!
It seems that there would be a significant demand for this type of thing for those folks who purchase the upcoming KAT500 remote tuner (me, for instance). I'd like to suggest integrating this type of capability into the tuner/controller design. The hardware could be optional so that only those who use it need to pay for it - perhaps a second remote box connected to the tuner box? Basic functionality: Ability to select a number (4 or 6?) of remote antennas from the K3 (or in-shack KAT500 controller if one is used). Ideally the user should have ability to do some mapping of the selection vs. band, etc. Only connection to the remote tuner should be the single coax. Also provide a 12V signal at the remote box for each antenna as it is selected so that the user can power another relay or two for additional configuration if needed. For example, to common the conductors of an open-wire line feeding a doublet so that it becomes a Marconi vertical. All features should work with either the KPA500 or a barefoot K3. Other suggestions? 2011 could be a fun year ;>) 73 Craig AC0DS ______________________________________________________________ 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
