K Pod mis triggering

ke9uw
 

Has anyone had mis triggering? Often used buttons trigger the wrong macro sometimes. This is my third one. They last about 6 months and then mis trigger. I moved the macros on the offending buttons to other buttons and all works well again for the macros I use a lot. Probably for another 6 months.

Finally, I closed all of the programs and rebooted the computer -
problem solved, at least for now. Still not sure what caused the
issue but I believe I am in good shape now.
This is a typical Windows "resources issue." It is one reason that
Windows Support professionals typically recommend that any Windows
system be restarted (not reboot - RESTART which forces a reload of
the low level hardware drivers) on a regular basis (daily). In
addition, the first step in debugging any problem with I/O (USB,
hard drive, video, etc.) should also be a *RESTART*.

The problem is generally an unrelated program or driver with a
"memory leak" (using memory space or "handles" and not releasing
them when done) or a program that writes to memory space that is
not properly assigned to it.

Re: Remote ON control of K3 - How W5AJ implemented

I use the ethernet -> 8 relay module http://vkmodule.com.ua/Ethernet/Socket4.html

It is switching on/off everything at the remote site: K3, linears HF and 50 MHz, antenna relay unit and rotator controllers.
I'm sure there is a lot of this stuff made in BY

Re: K3 RTTY issues with N1MM+

It is necessary to:

1) Set the USB Port to Option C: Limiting Speed (in Misc -> Tx Port)
2) Set Misc -> Tx Port to COM-TxD(FSK) and *not* Sound + COM-TxD (FSK)
3) Check PTT on the FSK Ports in microHAM USB Device Router
4) *DO NOT* use "PTT via Radio Command" [in *ANY* mode] in the N1MM+
Radio Port.

N1MM+ uses a *separate copy* of MMTTY so one must make (1) and (2)
through the N1MM+ Digital Window *FOR BOTH RADIO 1 and RADIO 2* if
using SO2R or SO2V.

Re: Elecraft K3s with P3 and Steppir SDA100

Randy Farmer W8FN
 

It is possible to rig a cable to the SDA100 DATA IN port that will simply monitor frequency via traffic on the RS232 bus if you have installed the optional transceiver interface module, but this is a one-way (receive only) path that won't let you control any aspect of the SteppIR. It will only allow the controller to follow the radio's frequency (and I'm not sure if the SteppIR interface is smart enough to read transmit frequency -- which could be important if you do much split frequency work). The interface cable can tee off the RS232 connection at the P3 PC port. It connects only the RS232 TXD line (pin 2) and ground (pin 5). A good way to deal with this connection would be a N6TV Serial Box. I've attached a copy of the SteppIR drawing for the Y cable for this link. The SDA100 MUST be configured for the same baud rate as the radio for this connection to work. PstRotatorAz will allow full control of the SteppIR via the DATA OUT port, but you must provide an RS232 port and connect it to the SDA100 using a null modem cable (pins 2 and 3 interchanged at one end).

The software is only used to invoke CAT info from the K3.
With no software and AUTO Inf activated in the Conf menu the same is achieved: each change of the K3 is forwarded on RS 232.
Works fine with my K3/Steppir combination.

Re: K3 for CW

Hi Martin,

On the issue of receiver latency compromising QSK operation, I don't think the T/R switching necessarily introduces any significant latency. (My RJ-1 vacuum relay switches in 1.4 ms!) Receiver recovery can be made fast enough by proper AGC design. However, a DSP unavoidably introduces delay, in addition to the inherent delay of any narrow filter. I think the DSP delay can be reduced by using a faster processor and/or sampling rate, but I'm not sure. Perhaps someone can fill us in.

Hi Scott,

your observation is correct, at least in particular. I don't have now any ricebox to confirm this. Anyway some numbers can be measured with Keying Analyzer by Nick, WA5BDU (attached), of course some not. I agree, a separate RX and TX with a 6AH6 antenna switch is unbeatable stellar performer although it introduces some level of attenuation into RX path. The "processorless" were much better (speaking about QSK) than the modern DSP/DDS gear. AFAIK the RX "recovery time" is mostly introduced by firmware built-in delays. Manufacturers won't allow any artifacts on the receiver audio during the switching time, unfortunately no firmware allows to adjust it. Anyway, the K3 with new synthesizers KSYN3A is still the best QSK radio on the market - if you have other info, tell me, please.

My idea is to extend the WA5BDU gem to measure RX audio. It seems that it will need another channel detecting the presence of an audio signal. I plan to get in touch with WA5BDU to do this.

Hello Martin,

I've been using QSK for many, many years, going back to the days of vacuum tube radios. The one thing that disappoints me about the K3 and other modern DSP radios is that the receiver latency is so long that even at 30 wpm or so, you can't hear between dots and dashes, only between letters or words. Even my old FT-1000D (no DSP) is much better. Have you noticed that? I really miss the transparency fast QSK gave us. I guess that's the price we must pay for the benefits of QSK.

I used a SteppIR with the SDA100 controller for several years. I used PstRotatorAz set to track my logging programs (DX4WIN for general logging and N1MM+ for contesting). I purchased a two-port Gearmo USB to RS232 converter and used one port to drive the SDA100. You connect the RS232 interface to the SDA100 DATA IN port. It worked very well. PstRotatorAz is an excellent program that will do lots of things besides control rotators, and it's well worth the small one-time registration cost.

Thanks, Joe!

The only config setting that differed from your suggestions was TX Port was set to “Sound + COM-TxD (FSK).” That would explain why AFSK worked. I’m not sure when that got changed, except I was fiddling with it during the contest trying to get something to work. Anyway, everything seems to be OK now.

Re: K3 RTTY issues with N1MM+

wonder if the other computer – on AFSK had VOX on

or which route the PTT was wired with different test rigs

for K3,  you might resolve using the “Comm PTT” on Ports setup page

Not my favorite but worth testing (That’s a writelog screen – assume N1MM has similar)

 

PI4C,  PI4CO and PI4COM are all found in the recent RBN link given on web page

Hello,

 

During the RTTY contest last weekend we noticed a problem that our transmitted text was abrupted.

A lot of times our call was transmitted as PI4C or PI4CO instead of PI4COM.

 

We used the latest version of N1MM+, MMTTY, Microkeyer MK2 and a Elecraft K3.

N1MM was configured as SO2V.

 

If I looked at the digital interface window the text was transmitted, at the end the software disabled the PTT of the radio.

But the radio was still busy transmitting the text, the FSK led was still flashing, but the software disabled the PTT.

I try to find what was happening or was changed, but I couldn’t find any solution for it.

 

So we changed it to AFSK and all worked fine again.

If I started MMTTY without N1MM it worked fine.

 

I checked it at after the contest and I come to the following conclusion:

The same computer setup with another K3 radio, other Microkeyer interface => same results.

Same computer setup with TS990, no problem

Other computer setup with the same K3, same problem.

 

I asked a friend to test his K3 and he has the same issue.

 

I hope someone has a solution for it, I am sure it must be something simple, but I can’t find it.

Re: K3 for CW

Robert W5AJ
 

Ben, an excellent choice
the 250Hz helped my 160 meter country count, could hear better!!
Indeed the DSP part of that was cranked to 150hz (that's about as tight and still being useful)

Look at the filter curves. The 400hz maybe more of a 350hz filter (ah, memory...)
I set the configuration of the 250hz to start at 300hz and the 400hz filter to kick in at 450hz.
just a preference
The 400hz is also great RTTY filter

it's correct to say don't use the 250hz as much as 400hz but it's worth being there.
if it's one or the other - 400hz

also in one of the QST reviews of K3 - there is a sidebar on the filters
it's worth finding and reading

Ben,

I can tell you that when I got my k3-100 10 years ago, my CW operation jumped from 50 per cent to around 80 per cent. As you've surmised, it's a great CW rig.
As for filters, I suggest iether the 400hz or 200hz filters. The 200 is a good idea if you want to do a lot of contest or DX operating. If your operating is more casual, the 400hz filter does a fine job. I use an 8 pole 400hz filter, which does a terific job. Good luck. Lou WA3MIX

I experienced a very similar problem using FSK, which switching to AFSK

I encountered a first-time problem with the K3s in the CQWW RTTY test last
weekend. I was using MMTTY, N1MM+, microKEYER II, Win 10. I always use the
K3s in FSK mode.
After a bit of sleuthing, I couldn't decide if this is a K3 problem, but
thought I'd submit to this group for starters. I will also check with the
MMTTY group, and if necessary the N1MM group.
Here's the story:
As usual, I had the setup all ready to go in the morning and even made a
handful of contacts. Everything worked as normal.
At the start of the contest however, I noticed that the K3 was sending
rather slowly, with a bit of "jerky" quality. After a few minutes, as the
problem got progressively worse, I started looking for answers. I checked
all the usual stuff:
- All K3 settings, microKEYER II, N1MM configuration and MMTTY setup were as
I have used them for years;
- I had not done a recent - in the past several days -- N1MM update;
- Thinking it might be a Win 10 timing error, I disabled the anti-virus
software and turned off all unnecessary background processes;
- Tried changing the baud rate in MMTTY and the K3;
- RFI? I reduced the power to QRP, transmitted into a dummy load, added more
ferrite on several cables.
.all to no avail. By this time I was getting worried. On a hunch, I switched
to AFSK. Behold! Transmission was back to normal. So that's what I used for
the next several hours. However. My band-changing macros default to FSK in
RTTY mode. Every time I changed bands I was back to the same problem.
After I took a 4-hour break for some shut-eye, and started on a different
band, FSK was working normal again. But only for a few minutes before the
stuttering slowdown began again.
Today I did some additional poking around, but I'm not finding the answer.
I've tried MMTTY standalone, everything seems normal. Does this sound like a
K3 problem?

Throughout the week I tried several times with various combinations of the
above. I have not been able to duplicate the problem at all.
Ideas?????

Re: K3 RTTY issues with N1MM+

If using FSK, make sure PTT is being generated by MMTTY *not* N1MM+.
Also make sure you have selected "COM-TxD(FSK)" and *NOT* "Sound +
COM-TxD (FSK)" in MMTTY's MISC -> Tx Port dialog. Finally, make sure
the "Char. Wait" and "Diddle Wait" sliders are fully to the left in
MMTTY's TX tab.

Note: those settings must be made from the N1MM+ Digital Window
*NOT* in a stand alone version of MMTTY.

See the example configuration for N1MM+ and MK II in Router (Help
