No, Brian. I have done none of the software mode settings. I’ll take another look though and more testing.
Thanks and 73, Terry, W0FM From: Brian Waterworth [mailto:brian.waterwo...@gmail.com] Sent: Monday, August 07, 2017 4:17 PM To: Terry Schieler Cc: Elecraft List Subject: Re: [Elecraft] K3: Odd ALC behavior Hi Terry, I have actually disabled all those settings in WSJT-X. I don't let WSJT-X put the rig into data mode (from the Radio tab - MODE = NONE). I don't remember the power settings by band on the Audio tab within the settings dialogue. I setup my KX3 ahead of time for digital modes (using a macro) and leave it that way for all data modes (FLdigi, WSJT-X, etc.). Do you have any of these options selected? Have you tried disabling them, setup your sound card, etc. as per Don's et al. instructions and then changed bands back and forth? regards, Brian VE3IBW On Mon, Aug 7, 2017 at 4:52 PM, Bob McGraw K4TAX <rmcg...@blomand.net> wrote: There is a feature in WSJT-X that saves power setting and tune power per band. So, to correct your concern, select the option and then set the value per band.
