For those using WSJT-X, sometimes I find
the K3s is locked as transmit but there is no RF being sent and no Rx from the K3. Looking at the P3 I see a jitter on the upper half of the screen as if there was a tiny output but no Rf is seen on any of the three SWR meters in line (K3s, AP3 & LP-100A). I couldn't get WSJT to receive, looked at the settings, all were correct and as is sometimes needed with WSJT-X, I rebooted to get it to work properly but it still did not lock onto the K3s frequency. Rebooted again and then I realized the K3s was in that TX condition with both the red & yellow LEDs lit and that jitter on the P3 upper screen. This happens every so often and what I have to do is touch any of the buttons on the K3s and it disengages this situation. I did that to deal with the issue I mentioned above. I could restart the K3s but then I'd have to restart LP-Bridge and wait, so I use the quick fix. Anyone experience this and figure out how to prevent it?

This problem is not unique to the K3. My Yaesu FT-1000mp does the same
thing -- locks up in transmit mode with no RF output and I have to turn it off to regain control. The lock up is intermittent, and some days it never happens. Rebooting everything works for a while, but when I least expect it, the lockups will start again.

Bert and Gary,
Have you looked for a computer problem? Such as having both PTT via command and via an RS-232 signal line? Do you have both VOX on and another means of keying the transceiver? 73, Don W3FPR On 11/13/2017 3:07 PM, Bert Garcia N8NN wrote: > This problem is not unique to the K3.

Using hardware PTT using Dtr or RTS is technically fine but many software packages will default to having them on with the consequence that the transmitter is in transmit mode if PTT is set to dtr. It becomes more and more complicated with more software hooked up. I have yet to see any software that cannot be used with software cat based PTT. It gets rid of most issues. As I said it is fine, but it takes more effort to make sure everything is set correctly. It also is possible that you will have to go into the driver advanced options for the serial port and turn off interrogation at start and other possible values.

won't have any issues with transmit coming on when you don't want it.

> Play it safe, just use software Ptt for everything. BS! Many rigs have race conditions in their processors. *NEVER* use software PTT and stick to hardware (RTS) switching only - particularly if you have the need for external sequencers and audio switching. If you have a problem with hanging PTT with hardware switching, fix the common mode RFI issues in your shack! If you don't fix them now, they will bite you later (and somewhere you don't expect). 73, ...

I've seen this occasionally too. I've had a number of odd malfunctions of USB-connected devices in the presence of RF.

You may be putting the performance of your station at a disadvantage with that approach, compared to using WSJT-X with CAT to keep TX audio in the range 1500-2000 Hz. The roofing filter may have a fair amount of group delay inequality at the edges of the passband, which can lead to inter-symbol interference on digital modes. I don't know how serious, if at all, this is in practice, but I know one very clever engineer who regards it as enough of a problem to have had a custom roofing filter manufactured for his K3 to reduce it. He mainly works EME with JT65. 73, Richard G4DYA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Richard and all,
The proper place to cure "RF in the shack" problems is in your antenna system. A good common mode choke (many call it a balun) in the antenna feedline and running the feedline at right angles to the radiator (assuming a dipole) to keep the feedline from picking up radiation from the radiator. If that physical configuration cannot be avoided, then an additional common mode choke at the shack entry point can help. In the case of off-center fed antennas and end-fed antennas, often the common mode current on the feedline can be difficult to cure. Use of one or more of the effective "baluns" described by Jim Brown K9YC at http://audiosystemsgroup.com/RFI-Ham.pdf will help. With effective common mode chokes on the antenna and feedline, you should not have to use ferrites on every cable in the shack - a much more sane answer IMHO. 73, Don W3FPR On 11/13/2017 5:46 PM, Richard Lamont wrote: > On 13/11/17 19:12, Gary Smith wrote: > >> For those using WSJT-X, sometimes I find >> the K3s is locked as transmit but there is >> no RF being sent and no Rx from the K3. >> >> Anyone experience this and figure out how >> to prevent it? > > I've seen this occasionally too.

Not necessarily true. If, for example, equipment in the shack is not
properly bonded together, an antenna close to the shack will put a lot of RF in the shack, which will induce RF onto cables connected to equipment, and is likely to couple into equipment. If an antenna is working as an antenna and it's close to the shack, it WILL put RF in the shack -- that's what it is intended to do! Proper bonding is described in this set of slides http://k9yc.com/GroundingAndAudio.pdf and in N0AX's new ARRL book on Power, Grounding, and Bonding 73, Jim K9YC On 11/13/2017 3:10 PM, Don Wilhelm wrote: > With effective common mode chokes on the antenna and feedline, you > should not have to use ferrites on every cable in the shack - a much > more sane answer IMHO. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

The CAT and PTT are on different COM ports, per the installation instructions for the microKEYER II when using WSTJ-X. And it's not a stray RF problem as I have all the equipment bonded together, ferrite cores on the audio and control lines, a line isolator in the feedline where it enters the house, and line isolators between the rig and amp and between the amp and antenna tuner. The lockup happens when running only 30 watts with FT8. It never happens when running a KW on many other modes. I run RTTY, PSK and other digital modes with no problems.
Thus, I suspect the issue is associated with the WSRJ-X software as the same issue occurs with various transceivers in multiple locations.

Use software PTT in the applications while W4TV figures out what is going on with the MicorHam gear.

What Joe, eluded earlier is actually true in some cases. Software can bombard the serial port with so many commands, without listening to a response and then issue the cat command. The problem there is the radio is processing all the other commands and the PTT is delayed.
In wsjt if you are using it alone with the native cat support and a k3, the data rate is very low, not like something like n1mm. There you can use the cat commands for Ptt without any issues. On the other hand, just turning the computer on can toggle the dtr and thus the radio can go into transmit. There it requires disabling advanced parameters in the serial port drivers, to turn off interrogation of ports. 73 Sent from my Samsung Galaxy smartphone. -------- Original message --------From: Don Wilhelm <[hidden email]> Date: 2017-11-13 7:08 PM (GMT-05:00) To: [hidden email], [hidden email], [hidden email] Subject: Re: [Elecraft] WSJT-X K3/K3s hanging as Tx Bert and all, Use software PTT in the applications while W4TV figures out what is going on with the MicorHam gear.

In split mode, it will adjust the Tx frequency so that the audio tones are always near the middle of the the passband. -ch 73 de AI6KG On Mon, Nov 13, 2017 at 3:01 PM, Richard Lamont <[hidden email]> wrote: > On 13/11/17 20:18, Jim Brown wrote: > > On 11/13/2017 11:12 AM, Gary Smith wrote: > >> For those using WSJT-X, sometimes I find > >> the K3s is locked as transmit but there is > >> no RF being sent and no Rx from the K3. > > > > I've been using WSJT-X since it was first introduced several years ago, > > and I've never had this problem.

Wstj-x has a lot of issues communicating with rigs. What I have found is For example, on the k3, it will change modes before it changes bands. The result, when you are on the new band you are in the wrong mode. On the Yaesu ftdx radios, it puts the radio into USB instead of data mode for transmit, and rtty mode for receive. It does not handle split correctly on the ftdx radios either. This is more important for yaesu rigs because they can have per mode parameters for gain and so on. It is quite possible it is doing something wrong when it comes to Dtr control. On the other hand you can try to use the omnirig entry in wsjt x for control, but it also has mode issues. Not sure about the k3. That may work better. 73 Tom

Damn it Don! *DON"T TELL USERS HOW TO USE MICROHAM PRODUCTS* The microHAM instructions are very clear - *NEVER USE CAT FOR PTT* YOU HAVE NO BUSINESS HANDING OUT INSTRUCTIONS THAT VIOLATE THOSE OF THE MANUFACTURER. How would you like it if I told Elecraft users to run their transceivers at 24 V to minimize IMD in the power amp? Using CAT for PTT results in hot switching of amplifiers, antenna relays, and other devices like antenna preamps while using hardware PTT assures proper operation of sequencing circuits that assure audio, external antenna switches, amplifiers, etc are switched *before* the transceiver is placed into transmit. Even the K3 PTT to RF delay is not sufficient to accommodate switching delay in old amplifiers, EME sequencers or the LNA/preamp bypass relays for external (active) receive antennas. > Are all those having a similar problem using MicroHam something? or > does it occur with other interfaces. It occurs with other manufacturers products and CAT PTT - nearly every manufacturer has a race condition in their controls when CAT and hardware are mixed. Since CAT PTT has serious problems with hot switching and most software includes specific PTT to CW and PTT to Audio delays specifically to avoid hot switching, use of *HARDWARE* PTT is always the smart choice. 73, ...

Thank you Joe for going public with that instead of private email!
I will not respond other than this. 73, Don W3FPR On 11/13/2017 7:46 PM, Joe Subich, W4TV wrote: > > > Use software PTT in the applications while W4TV figures out what is > > going on with the MicorHam gear. > > Damn it Don! *DON"T TELL USERS HOW TO USE MICROHAM PRODUCTS* > The microHAM instructions are very clear - *NEVER USE CAT FOR PTT* > YOU HAVE NO BUSINESS HANDING OUT INSTRUCTIONS THAT VIOLATE THOSE > OF THE MANUFACTURER.
