One possible gotcha is that the sub receiver is an option on the K3, and you need to set a configuration menu item to say that it is installed. The process is mentioned in the KRX3 manual and at the end of the K3 manual where the various menu items are described.
Hold the CONFIG button (the button is labeled "Menu") located near the top left of the front panel. Rotate VFO B until you see "KRX3" in the bottom line of the LCD screen. Rotate VFO A to Ant = ATU or Ant = bnc depending on your use of a 2nd antenna (mine says ANT = ATU). Leave the menu (by tapping the MENU button again), then turn on the SUB by tapping the SUB button on the bottom right of VFO A. the "SUB" icon (surrounded by a box) should appear beneath the two VFO frequencies on the LCD screen. Adjust the main and sub receiver volumes with the concentric RF and AF gain knobs. You can decide whether to hear the sub and main mixed into both headphones by the L - MIX - R menu item, mine is set to A b so that I hear the main and sub receivers simultaneously, one in each ear. Other possible problems are that the sub receiver may be switched to a different antenna, to check this, HOLD BSET (to the top right of the LCD screen), then set the ANT to the appropriate antenna for VFO B and make sure that the RX ANT is as you expect it to be. 73 de Dick, K6KR -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Jim Brown Sent: Sunday, June 20, 2021 12:06 To: [email protected] Subject: Re: [Elecraft] New K3 user...

With headphones set for stereo, you'll hear it in your right ear, with the main RX in your left ear. Once it's on, a long push on the SUB button puts you in Diversity mode, for which you need a second antenna and an input for it. Perhaps study of the rest of manual might be a good thing. Over the years, I've owned ICOM, Yaesu, an Ten Tec rigs, and their user interfaces have all differed radically from each other. The Elecraft UI is, by far, the best of them all, but you have to RTFM to understand it. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
