Re: [Elecraft] K3 ATU Problem
HI, After a bit of button pressing I have noticed the following: When doing a first tune using the internal ATU the tuning power is a set 5W. Immediately doing an extended tune the tuning power toggles to 10W. It does indeed flash up in the VFO B window whilst tuning is in progress. This is in no way controlled by any power level set by CONFIG>TUN PWR. My CONFIG>TUN power setting is 18W which I use to preset my Acom 1000 amp tuning.

Re: [Elecraft] K3 ATU problem
If an ATU tune finishes like that, with --, then it did not find a match! (and will be in a random state). You don't have enough power for a successful Tune. Try running the TX gain calibration with the K3 Utility. Or, with a dummy load, ATU in BYP, make sure TUN PWR is at "nor", then set pwr to 5.0 watts exactly and long press XMIT to send a carrier for several seconds. (That will do a manual tx gain cal on that freq). Then engage ATU and do an ATU TUNE and it should find a match. If the TX gain cal fails, something is wrong with the LPA.

Re: [Elecraft] K3 ATU problem
First thought, is your ATU is in bypass? Is the "ATU" icon showing below the 4th digit of VFO A display? 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/13/2021 6:43 AM, Eric Rosenberg wrote: When I tap ATU TUNE, I hear the relays clicking, see no output from the radio.

Re: [Elecraft] K3 ATU problem
Mark, Do you have the correct antenna (ANT1/ANT2) selected (this is a per band setting)? Have you tried it by tuning into a dummy load? If it tunes into a dummy load, then you will likely find your problem in your antenna system. 73, Don W3FPR On 4/20/2018 2:01 AM, Bonjour de Marc ! , F4TXR wrote: Hello everyone ! , I have a problem that suddenly happened, my atu on my k3 does not work more correctly! we can hear him agree, but it's like she does not find him as a result, the ROS remains high, regardless of the bands.
