OK,  But here is what I see.

I have the P3 connected and following the zero beat method, I get the side tone on the monitor to nicely zero beat, and the dial reads 10000.065 and any changes I make to the main dial moves the P3 display off center.  I have tried the main dial and the number 2 and 3 to no avail.  Hummmm

Terry I did it with an SDRPLAY RSP1 on the IF OUT. Software HDSDR.
Everthing works fine, only at 6m band CW 1 khz too low and the VFO is running in the other direction.
All other band are working exactly, if you did set the correction for USB, LSB, CWU and CWL.

Unwanted "monitor mode" in digital modes after firmware upgrade

Alex OE3JTB
 

HI group

I am using a K3, MIcrokeyer II Windows 10.

I didt a firmware upgrade to 5.57, 2.88 3 days ago and since than I had ha monitor mode, which never was there before.

Means in Winwarbler or even in HDSDR with SDRPLAY I see my transmission.

I changed nothing else on the setup of this combo, but now its here :-)

Any way to "switch" off this unwanted monitor mode?

Re: [Elecraft_K3] K3S and RTTY (FSK D)

Rich,

Thanks for your reply and suggestion. When I installed WSJT-X for FT8 set up DATA A, I changed a K3S CONFIG setting I had been using for RTTY FSK D. That change plus some hardware COM port issues (another story) were preventing RTTY FSK D from working. For now, as best I can tell, it's all working again.

CW, SSB, and FT8 (DATA A) all still work okay. MMTTY, and WriteLog, RttyRite, and mtty.ocx worked okay before I tried to operate in the ARRL RTTY Roundup this weekend. What has changed from previously when it all worked is: Windows 10 updates, and the installation of NTP and WSJT-X.
I have reinstalled WriteLog (latest version), MMTTY 1.70, and the drivers for my hardware COM ports. Then I set up MMTTY again page by page from AA5AU 's website. Still no joy.

For ASK D I'm using the interface shown on page 99 of Fred Cady's K3S book - real COM port to K3S ACC for PTT and FSK in. It worked fine before, but not now.

Any suggestions sure would be appreciated.

I use WSJT-X and the Freq Cal mode.  The setup is the same as used for WSJT-X.    I manually via the software select 2.5, 5.0, 10.0 and 15.0 MHz signals.  Typically the software returns a DF of less than 1 Hz.  If it is more than 1 Hz in error, I will by the K3S menu adjust the reference oscillator a few Hz.    My results have proven very successful and accurate with normalized errors of +/- <0.5Hz for frequencies measured.

I use a very simple method.

 

CW mode on K3 tune in an on air standard frequency transmission. The higher the frequency the better but you need a reliable consistent signal. I normally use either 10000KHz or 9996KHz (Russian TX ideal for UK). K3 for minimum bandwidth and display to Hz rather than 10 of Hz. Switch on auto CW tune and press spot button to auto tune the signal. The display will then show the offset from the standard. Adjust the K3 reference frequency value, auto tune again. Repeat as necessary.

 

Due to different modulation schemes can only do this when there is a carrier or CW keying. It is best to avoid doing this with a disturbed geomagnetic field or dawn/dusk on the path as the ionosphere height and propagation mode can be  unstable causing some Doppler shift of the signal.

Re: K3 will Tune into an antenna but no Power on SSB or CW

Richard Jones
 

Ok further info..

It actually doesn't find a tune... I'm not sure if something has changed or if I just didn't notice earlier and presumed that it had tuned... but now it shows 5W on the display when tuning into a resonant antenna.. I hear the usually whirring and clicking from the tuner... when that stops it does display the "--"

I was a little reluctant to start really pulling the radio apart as it isn't mine... I'll have to confer with the club radio officer before proceeding but will pass on your suggested next step.

Thanks... I'll post as we move forward..

Re: K3 will Tune into an antenna but no Power on SSB or CW

Richard,
Will the display show dashes when the tune button is pushed? With a dummy load connected, can you increase power when in tune (transmitting a tone) then drop down to "0" by itself? If so, try re seating the ATU board.?

Thanks for that but I mentioned I'd already done that. Multiple times. I just drove to Elecraft and dropped off the rig. One convenience living in the Bay Area is having the Elecraft expertise just over the hill from me. Cheaper and faster to drive it over in the Honda than to mail it!  I will advise the group regarding what they find. A couple weeks to play with the HT-37 and Viking Ranger, a roughly 60 year step back in technology. Fun simple tube stuff.

About a year ago I sent my K3 to Elecraft due to the output power behaving erratically on AM operation. Now it started acting up once again. This time on bands higher than 14 MHz the output power can take several seconds to ramp up to 100 Watts output. I'm referring to already having the output power control set for 100 Watts and then pressing the XMT button or setting to FM mode and keying the mic; in other words simply commanding the K3 to put out a 100 Watt carrier. Sometimes on 29 MHz it's particularly bad and will sit at about 50 Watts for 15 seconds and then slowly creep up to 100. Sometimes it initially continues past 100 and stops around 115 Watts and then settles back to 100.
Thor original repair replaced the driver and final FETs within the LPA and also changed to new gold faceplate connector pins.
So I opened it up and found that Q3 on the LPA was blown "open". Q3 is the bias control switch, an SMT bipolar transistor. I honed my SMT skills and I replaced Q3. I also replaced the LPA's driver and final FETs; in other words the 3 primary FETs in the LPA. I tried FW versions 5.60 and 5.50. I reseated the faceplate connections. I ran the transmit gain alignment and it fails usually on the 29 MHz cycle. The error message states "power cannot settle". One hint is I checked the transmitter gains and all look reasonable except 29 MHz which shows a gain of 115 for the HPA. Another hint on 29 MHz is the HI CURRENT warning shows occasionally.
Since the HPA does output 100 W I conclude it's not the issue. I also conclude that the LPA is OK especially since I just changed all of its FETs. So what else is there to cause a slow ramp up in power? Keep in mind this problem is only seen at frequency bands higher than 14 MHz albeit perhaps it's just slightly doing it on 14 MHz. The rig operates apparently perfectly from 10 MHz on down to 1.8 MHz.

Has anyone seen this erratic power behavior and if so what was the root cause? Thanks in advance.

Problem in low pass filter sections? Spurious output? Bad connection from output board to antenna connector on back panel?

All the testing is being done into a known good 50 Ohm dummy load. The test setup is clean.
