Mic gain goes to zero using N1MM
Locked
 
|
Evening all,
I was setting up N1MM with the K3 for the Virginia QSO party tomorrow when I noticed the following strange behavior. Whenever I press any of the FKeys on N1mm (with the exception of F4 and F12), the mic gain on the K3 gets set to 1. I cannot remember this was always this way or something has changed in either N1MM or the newer K3 configuration files. So a couple of questions before I jump over to N1MM with a bug report; has anyone else experience this problem? Any suggestions to check on the K3? Best regards, Jerry, W1IE (who is patiently awaiting the new Syth boards) ______________________________________________________________ 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] |

Jerry,
Does the K3 respond normally when operated from the buttons and knobs? If so, the problem lies with the software that you are using - in this case, N1MM - unless there is a bug in the K3 command structure, and AFAIK there have been no recent changes. 73, Don W3FPR On 3/20/2015 9:00 PM, Jerry Knowlton wrote: > Evening all, > > I was setting up N1MM with the K3 for the Virginia QSO party tomorrow when I > noticed the following strange behavior. > > Whenever I press any of the FKeys on N1mm (with the exception of F4 and > F12), the mic gain on the K3 gets set to 1.

I have experienced this same problem over numerous N1MM versions (legacy and Plus). It is very intermittent and I'm unable to identify a specific command or cause. It's happened to me on both my shack and portable computers. This symptom does not show up with my daily logger (N3FJP ACLog) but it has occurred with both of my K3's.
I use the "typical" K3 commands for either keying DVK memories or audio from my computers. I don't use any of the mic gain command strings in N1MM+. Are we the only two who have experienced this? I've Googled this previously but not found any threads on the subject. I'm glad to read (sort of) I'm not alone. I have operated many hours (all of Field Day) without this symptom appearing. Yet, it happened a couple of times in last weekend's Colorado QSO Party. It's a mystery to me. 73, Bill, K8TE |

When I lose transmit power (and once it goes, it’s gone until I do a power off/on or switch to ANT2 and back) I checked the Mic Gain and it was normal (31 for me). The power level was also at its proper setting. It has happened both using N1MM+ and my daily logger (MacloggerDX). I use NO CAT commands with MLDX. That is at a time of failure, I have a Mic Gain of 31, a Power level of 50W or so, I key the rig (footswitch), the K3S goes into Transmit Mode (Red LED, receiver goes off) but there is no power output shown, and no SWR shown (as would be if the antenna was disconnected externally). I hear myself perfectly well in the headset monitor, indicating there is a good connection from the microphone through to the radio. Just no output power. And as I said, switching to ANT2 and back to ANT1 brings all to normal, as does a power reset. To me, something is intermittent in the radio internals, but I have no idea what. Elecraft advised me to try to reproduce the problem with a “no frills” setup: no computer, no amp, just the K3S into a dummy load. I’ll try this today, but of course with intermittent problems it may or may not recur. -Rich KE1B ______________________________________________________________ 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] |

In my case, the Mic gain is normally set to 8-9 (CM500 headset). The anomaly decreases the Mic Gain to zero. I manually reset it to 8-9 which restores SSB power output to normal. I haven’t tried any other actions to restore the Mic gain. All indications I have this is a Mic Gain problem. 73, Bill, K8TE From: KE1B [via Elecraft] [mailto:[hidden email]]

We must carefully avoid our decades-ground-in tendency to think of troubles in our familiar and comfortable analog fashion. I do include myself in this habit and sometimes catch myself going retrograde, having to do a brainwave CTL-ALT-DEL, and start over from the beginning. This trouble is presenting inside the K3's SDR dotted line. Of the eight "pots" on six shaft centers on the left side K3 front panel, all those rotational functions *advise* the CPU of their state via multiplexed one and zero state data lines. There is no gain potentiometer inserted anywhere in the various audio paths, nor is there a steady state control voltage from a potentiometer controlling a linear pass transistor in the audio string anywhere, thank your lucky stars. Remember "scratchy" audio? Just another of the analog bugaboos happily banned forever by the K3's mostly SDR hybrid scheme. The MIC control function uses a *shared* encoder assigned three separate unrelated settings. If the encoder or its physical data connection to the CPU was a problem, it would affect all three functions MIC, SPEED and DELAY on the front panel. I have heard of the encoder going bad and needing to be replaced. If the encoder is miscellaneously sending a string of "decrease" encoder signals, it should also happen in SPEED or DELAY mode. All the encoder can do is send increase or decrease signals. You would have your CW and VOX delays going to nothing, or your CW speed going to the 8 WPM minimum. The CPU knows what function is currently "on the knob" and the static values in force for the three lower left encoder functions. Exactly one function at a time is currently assigned to the knob, and the CPU interprets a "decrease signal" accordingly. The decrease signal travels to the CPU over a multiplexed data line which is either there and properly working for many diverse functions or is not for all those functions. Doesn't this really start to smell like a program issue? That gets you to the next thing -- if it is a firmware bug, then the trouble is present for ALL K3 users running the affected firmware version(s). And we should have lots of reports because every single user of the firmware could be experiencing the same problem intermittently. The only program code that could isolate the trouble to a *few* users would have to be external to the K3. Is it possible for an external program to set the MIC gain? This of course is impossible in an analog radio priced for ham customers, so analog thinking would not suggest that. The trouble would have to be IN an analog radio. But since the K3 is digital, we note that page 1 of the K3 programmer's guide has "MG * Mic gain" cell in the command table cheet sheet. That just might be an "Aha" moment. If an external program intermittently sent an MG 000 command to the K3, you would inconveniently find the MIC gain set to zero, intermittently. Not a K3 intermittent physical problem, but a K3 *commanded* to set MIC gain at zero, a command which the K3 mindlessly obeys, as yet unable to read a contrary indication from the mind of the operator. Let me know when the mind-reading K7 shows up. I want one. Get rid of a lot of cables and input devices. I, myself, with my terribly soft and mumbly radio voice, with extensive trials managed to get a good setting for K3 SSB MIC gain, compression and TX EQ settings. I was directed to those settings, and had those settings confirmed as clear, punchy and understandable over the air, by the PVRC contest guru crowd. Predictably I haven't myself touched those settings in maybe three or four YEARS now. They are still where I put them. They better stay there, too. People don't hear me nearly as well when I'm non-K3-processed. It's like turning off the amplifier. Repeating myself, if it's a third party program on someone's particularly configured PC, or with a particular parallel combination of running third party programs, then the mic gain to zero problem would be scattered and rare. If it's in K3 firmware, it probably would have been caught in alpha or beta testing. If if got to the general field in a production release, Big E would have been buried in complaints. Myself, I would suspect something incoming on the control serial line like "MIC 010" losing ASCII digits and arriving as "MIC 0", or mangled to "MIC 000" or something like that. Does the K3 process a "MIC 0" command or consider that an invalid command? I don't know. But poor physical connections for external serial lines, or overloading USB hubs have resulted in mangled command strings, or two programs fighting for exclusive use of the serial line, and those kinds of problems far beyond Elecraft's control, are as common as nails. And by my reading of this reflector those troubles are frequently first blamed on the K3, even if the true chances of that actually being correct are worse than hitting the lottery. Do follow the support advice to disconnect all the external programs and see what happens. The complete list of all possible combinations of third party programs that can drive a K3 over a serial connection is an absolute witches brew of widely scattered quality, from the sublime to the simply awful, sometimes implemented in a hamshack with grotesque physical arrangements. There are programs in distribution that have known problems that the coder has no intention of ever fixing, for any number of reasons, and some have publicly stated such. What you got is all you are ever going to get with these. Meaning that your particular problem could have been reported to the author a thousand times without effect. That in a programming world that swiftly keeps moving on. And of course this is without mentioning the ubiquitous fallibility in PC Bios programs and operating systems. Elecraft is your friend. Respect the Elecraft. 73, Guy K2AV ______________________________________________________________ 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] |

I don't use any of the mic gain command strings in N1MM+. Is it possible that you have a macro associated with one of the memory buttons('s programmable function), which sets the MIC gain, and one of your lesser-used N1MM Logger messages is virtually pushing that button (SWT/SWH)? 73, ~iain / N6ML ______________________________________________________________ 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] |

Bill, Memory macros—nope. All the N1MM macros are the “standard” button pushes for the DVK messages. A raspberry Pi may be in the future for my station control now that an inexpensive touchscreen is available. But I will stick with N1MM+-K3 interface for now. In my shack I use LP-Bridge to provide virtual serial ports, including one to the K3. However, this anomaly has appeared when using my old Vista laptop with both N1MM Legacy and Plus. A passive logger could possibly indicate the anomaly’s source. Any suggests for a software logger? Consider that some other command could also be mangled into MG 0. The mangling can occur anywhere in the command. What would be useful here is a passive logger for the RS-232 connection. It would simply monitor the connection and log everything sent over it. It sounds like a Raspberry Pi application to me, but I like to play software that is near the hardware level. You could also do it with an Arduino, which gets rid of the OS, but also makes display output harder. YMMV. 73 Bill AE6JV Guy, I don’t believe I’ve indicated this is an analog problem. It’s most obviously a software/firmware problem. There is no “MG” command in the N1MM DVK macros: CATA1ASC SWT21; CATA1ASC SWT31; CATA1ASC SWT35; CATA1ASC SWT39; The only commonality between occurrences is N1MM (various versions) and a pair of K3’s with various firmware versions. There are no common cables, USB hubs, serial cards, computers, etc. That is not to say that some errant event occurs on rare occasions. It is interesting to not nothing else goes astray on the K3 when using N1MM. Since the anomaly occurred with a K3, and another K3 owner had a similar issue this year, I posted here first. Next I’ll give it a try on the N1MM+ e-mail group. I’m watching an episode of Sherlock Holmes on PBS as I type this message—what an appropriate coincidence, or is it? 73, Bill, K8TE Since the mic gain, displayed in a digit format, is reported as From: Iain MacDonnell - N6ML-2 [via Elecraft] [mailto:[hidden email]] On Wed, Sep 9, 2015 at 6:07 AM, K8TE <[hidden email]> wrote: If you reply to this email, your message will be added to the discussion below: http://elecraft.365791.n2.nabble.com/Mic-gain-goes-to-zero-using-N1MM-tp7600489p7607363.html To unsubscribe from Mic gain goes to zero using N1MM, click here. |

LP-Bridge proxies commands and answers polling from its own "virtual K3". Both are capable of causing abnormal operation, particularly with N1MM Logger+ and another program such as NaP3 polling at maximum data rates. In addition to N1MMLogger+ what other applications are running when this problem occurs? 73, ...

Yes Joe, it has happened on my old Toshiba with Windows Vista laptop running N1MM by itself. I don’t run NaP3 currently on the shack PC on which I run LP-Bridge. There, I usually have Chrome open as well. The anomaly occurred once during this week’s Phone Fray during which I also had an instance of IE open. On that computer, CPU cycles are not an issue. This PC runs on Windows XP, soon to be replaced with a “modern” Dell and Windows 8.1. For communications with the K3, I run N1MM+ through LP-Bridge via an on-board dual Serial port board. I don’t run LP-Bridge on my mobile/portable laptop. I tried it once, but it doesn’t have sufficient horsepower. With that computer I use a USB to dual serial port adapter for K3 communications. I have observed the anomaly on both computers although it rarely occurs on either. I’ll put together a more concise description for the N1MM+ reflector later today. Both computers have anti-virus and firewall programs running simultaneously. In their current configurations, neither has issues with CPU cycles during contesting. I use Startup Delayer to manage what and when programs come up on boot to help manage CPU use. That comes in handy during the rare occurrence when a re-boot is necessary during a contest (always be prepared). I also run the VE7CC CC cluster client when the contest allows and I choose to enter in the assisted class. Again, the problem has occurred both with VE7CC on and off. Let me add my thanks to all who have responded to my question! 73, Bill, K8TE From: Joe Subich, W4TV-4 [via Elecraft] [mailto:[hidden email]]
