[Elecraft] TX Gain Calibration
Good morning, I have just done a TX Gain Cal on my K3 and 160m came up short (4 watts). 1. Is this something I can fix or does it need to go to the Mother ship? 2. If it is not corrected, what are the ramifications of not having it done? 3. If it can be fixed by me, what is involved?

Re: [Elecraft] TX Gain calibration fails
Hi Joachim , How are you adjusting the power in each of the three power settings. Do you have the coax and dummy load connected directly to the K3? Trade out the short jumper to the dummy load to assure yourself it is good. After that, I would measure power with an external calibrated wattmeter. The K3 utility is obviously not seeing the power it is looking for, low by .5 to 12 watts depending on the power setting. 73, Bill-AK5X > On Dec 30, 2021, at 11:53 AM, wrote: > > Hi, > > I tried to go through TX Gain calibration on my K3 (after VCO MD cal), but > it fails (see below).

Re: [Elecraft] TX Gain Calibration Fails on 6 meters
Hello, K3S. S/N 11532 K3 Utility running on Mac OS 10.14.6 Mojave I found that running Transmitter Gain utility requires these settings within K3S Config menu to enable test to pass (with good 50 Ohm load on both ANT1 and XVTR-Out ports): Transmitter Gain tests: 5W test. requires Config - XVTR - OFF 50W test requires Config - XVTR - OFF mW test requires Config - XVTR - ON. I suppose this makes sense (turn the transporter on for the mW test which is used to drive the Transverter). 73, Dave KJ9I -- Sent from: http://elecraft.365791.n2.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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] TX Gain Calibration Fails on 6 meters
How are you doing the calibration - manual or computer? If computer, PC or Mac? Make sure you have the latest K3 Utility to do this. Recent versions of the K3 Utility had an issue with handling responses from the K3/K3S that caused calibration to fail. I believe they were fixed on the Windows version, but I don’t think that has been taken care of on the Mac yet. I will have to check to make sure. Repeating the process is worth while. My own experience is that it will eventually complete. 73! Jack, W6FB > On Mar 12, 2019, at 10:04 PM, Frank via Elecraft > wrote: > > I purchased Elecraft K3S S/N 11672 in August 2018.

Re: [Elecraft] TX Gain Calibration Fails on 6 meters
My K3S s/n 10163 I find my results are the same as yours as below. "On 6 meters the relay switches from LP to HP amplifier when the power is adjusted from 8 to 9W." "On 160-10 meters I hear the relay switch from LP to HP amplifier when the power adjustment is increased from 12 to 13W as described." Also noted with TUNE power set to 20 watts, all bands 160M - 10M operate normally at 20 watts displayed and measured. However on 6M when TUNE is activated the displayed power is 16 watts and the measured power is 16 watts. When PWR is set to 20 watts, the measured output is 16 watts. However, If I set the PWR to 100 watts the measured power is 100 watts. On 6M if I set TUNE Pwr to 25 watts, when Tune is activated it displays 21 watts and output is 21 watts. Clearly there seems to be an issue in firmware for 6M only. I recall sending the concern to Elecraft. At the same time, I don't consider it to be a major issue. 73 Bob, K4TAX __ 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
Re: [Elecraft] TX Gain Calibration Fails on 6 meters
I had the 50 MHz gain cal fail with the initial build of my K3s. Don't remember which power. I repeated the cal several times and one time it passed. I left it there. Not anxious to try it again.

[Elecraft] TX GAIN CAL Problem Fixed...(maybe)?.....
After noticing my Acom 1500 not producing full output on some bands (Acom tested good), I went off and started what I thought to be a short TX Gain Cal (which I had never done) to the factory assembled rig. This rig has functioned perfectly since I received it from the factory on 4/19/2011. I am not going into the myriads of runs on the cal procedure in the latest utility (1.15.12.7) and firmware, as I was very frustrated. I was successful in the 5W cal up to the 60M band where I hit a dead end. I looked thru the dozens of posts and tried all that had something to do with tweaking the computer inputs. No luck. Then, I noticed a few type of mechanical type problems, most I would not try in opening up the rig. I'm too old for that and my ham radio tweaking inside a radio are long behind me (8 years retired and full time caregiver for my wife). While running a sweep of another TX Gain Cal, when the run was inside the 60M band trying to find 5W (it was good at finding 3.4W or so), I lifted the rig at the front and let it drop an inch, out of frustration than anything else! *Lo and behold*, the run slowed, showed 5W and proceeded on to a successful 5W cal. I nervously selected the 50W process and yes, you know the answer, it worked like a champ. Going to bed now (almost 10PM now). I guess there is a loose pwb, component or cable inside? Maybe someone can give a guess at what might be wrong. If it is easy to get at, I could go in and start to tighten screws first, re-seat cables, etc.? BTW, the rig has never been dropped, etc. always sitting there waiting for the next DX station!

Re: [Elecraft] TX Gain Calibration Error?
I've not seen this, but your VFO B area is probably showing power supply voltage when a power level is expected. Can you save your configuration with the K3 Utility, then perform parameter initialization (EE INIT) then restore configuration? EE INIT is described in the K3 Owners manual.

Re: [Elecraft] TX Gain Calibration Error?
Thanks Dick, Thats exactly what I did do, EE INIT followed by restoring my configuration. All seems to be fine now.

I've not seen this, but your VFO B area is probably showing power supply voltage when a power level is expected.

Re: [Elecraft] tx gain calibration
No you're just able to have the dummy load on either port when you do so. ~Brett (N7MG) On Fri, 2010-06-18 at 20:35 -0400, Gary Lee wrote: Must I do this for each antenna port? __ 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 __ 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

No. Just one time on one of the antenna ports into a dummy load. 73, Eric On 6/18/2010 5:35 PM, Gary Lee wrote: Must I do this for each antenna port? __ 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
[Elecraft] TX Gain Calib state 157 error and no audio issues
I just finished building my K3 to the point of the test and calibration stage, where I encountered some issues. SYN calibration went fine, and the filters are set up. When I got to REF CAL, I found I couldn't use WWV because I wasn't hearing anything. I reseated the KIO3 board as well as the 2 daughter boards and managed to get a crackle from the speaker at power up and power down but still no audio. I used a freq counter for REF CAL but when I got to TX Gain Calib, I received the following error message using the latest version of the K3 utility: Starting 5 watt calibration Calibrating at 1.900 MHz IsSamplingComplete: Unexpected response DS@@\x80\x80; to DS; State 157 Calibration power settled at 0.0 W ; 5 watt calibration failed Elapsed time: 6 seconds I tried manual calibration on different bands but that failed also. I haven't seen any references on the reflector to an ERR TXG mentioning a State 157. I did recheck my filter settings and they seem correct. I've emailed k3support but thought I'd check here in case someone has seen this version of the ERR TXG issue. Does the fact that I could connect my laptop successfully to the K3 and use the utility indicate that the audio issue is probably with the audio daughter board and not the main KIO3 board? Thank you for any ideas on how to resolve either issue. -- View this message in context: http://elecraft.365791.n2.nabble.com/TX-Gain-Calib-state-157-error-and-no-audio-issues-tp5129241p5129241.html Sent from the [K3] 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
Re: [Elecraft] TX Gain Calib state 157 error and no audio issues
If manual TX Gain calibration is failing, then the automated K3 Utility version of Tx Gain calibration can't succeed either. The state 157 is just an internal variable in the K3 Utility, it's not a K3 state and doesn't mean much to anyone except me... The K3 Utility set the power level to 5.00 watts and then did the equivalent of pressing tune. The utility wants to see an SWR 2.0:1 and 5.0 watts in the VFO A and B areas of the display. Your K3 isn't transmitting, according to the display. I would wait until you can calibrate at least one frequency manually before trying to use the automated K3 Utility calibration. K3support is the right place for this. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of K9IR Sent: Tuesday, June 01, 2010 9:37 PM To: elecraft@mailman.qth.net Subject: [Elecraft] TX Gain Calib state 157 error and no audio issues I just finished building my K3 to the point of the test and calibration stage, where I encountered some issues.

[Elecraft] TX gain ?
Anyone seen this issue: When adjusting 50 watt TX GN (gain) on each band, some bands do not allow entire adjustment range to obtain 50 watts? i.e. while adjusting VFO A for exactly 50 watts the VFO B display may move in the following steps: 46, 47, 52, 57 watts and skip over - for example - 48, 49, 50, 51, 53 etc. This results in some band calibrations being above 50 watts and some being below due to the unavailability of all the power settings? This seems odd. Running Beta 2.23, 1.88 Rodger N4NRW ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
