I believe Mike's original question (not morphed) had to do with switching RX antennas for *diversity receive*...not for transmitting. See below: ####################################################### AE6WA wrote: When we use diversity mode antenna switching becomes a different problem than I have run into before. The usual antenna switch routes many antennas to one radio port. Some of us have many antennas that need routing to two or more radio ports. So I could imagine a useful kit would read K3 band decode and map something like 6 or 8 antennas to 2 or 3 ports and makes sure the K3 does not transmit into the other radio ports. Some attention to stations using two K3's or a second receiver might be useful also. Not sure what this would entail because I don't operate that way. http://mailman.qth.net/pipermail/elecraft/2009-April/109172.html ######################################################### You can connect up to 8 RX antennas to the RAS 8X2, and then feed the two outputs to RX ANT (Main) and AUX RF (Sub). You can then choose any combination (even including the TX antenna on ANT1 if you tapped RX ANT off on Main) without running the risk of RF being accidentally sent into the K3 during TX. This would only work for one TX antenna at a time however unless you added additional switching. Of course this also assumes you have some reasonable level of isolation between your external TX antenna and all the RX antennas. If you didn't have that, the RX antennas probably wouldn't work right in the first place due to interaction effects. 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/K3-add-on-kit-idea-tp2651047p2651837.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
