There are two antenna connectors on the back of each of these transceivers. Are they selected automatically depending on which band you are on or do you have to select one or the other antenna port in a menu? My Kenwood TS-570SG has two antenna ports also, but I have to select one or the other. I can't find anything in the Yaesu or Icom manuals about a menu setting for that. It hasn't been a problem until now because I'm only now adding antennas for 144 and 432 MHz. Thanks for any input on this question.
