Re: [Elecraft] Interface and Ham Radio Deluxe
If you connect directly to mic/speakers on both the PC and Radio be very careful. The PC speaker output can over drive the audio if you put it straight to the microphone of the rig and I would always advise using isolating transformers. You can spot people who have gone the 'straight through to mic input' route when they overdrive their audio and produce very wide signals. A better option is to use Line in/Line out on the PC and interface to an accessory socket that takes constant line levels. not lookied at the KX3 data inputs yet but if they are provided use them... Personally, I have used a US Interface Navigator. It provides excellent interfacing on both audio and computer connections. HRD is a bit expensive if you want the latest version, I well remember when it was free and there were a group of peopkle testing it and sugesting improvements and identifying bugs...

Re: [Elecraft] Interface and Ham Radio Deluxe
I just read the data part of the KX3 manual in more depth and it's now obvious that you have to use the mic in and speaker out from the KX3 for data. So, I will definately be digging out a fully isolated interface unit, which I used before getting the Navigator, if I decide to run data modes through the KX3. I would also recommend getting the IMD meter by KK7UQ to monitor your transmitted signals to make sure that they are clean.

You can spot people who have gone the 'straight through to mic input' route when they overdrive their audio and produce very wide signals. An isolation transformer does not solve the excessive level problem. For that you need an attenuator or voltage divider. Typically one would connect a 4.7K or 10K resistor in series between the sound card output and the mic input and a 470 or 1000 Ohm resistor from the mic input to the mic ground. That 20dB is about right for the sound card line/speaker output to an electret mic input. Substitute 47K or 100K for dynamic mic inputs or use a 500/1000 Ohm pot with the wiper to the mic input instead of the fixed shunt resistor. 73, ...

Re: [Elecraft] SDR software for KX3?
When I first started with SDRs, I had a Softrock that had substantial hum(p) around the center frequency. I added a pair of Triad sub-mini isolation transformers, ones with good high-frequency response, and found that instead of the hum(p) I now had a very narrow hole at the center freq. 73, Pete N4ZR Check out the Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com.

I've used Rocky, hDSDR, a few variants of PowersDR, SDRsharp, and a few others, on various Windows and Apple (iPad, iPhone) computers. Most programs have internal adjustments for phase and gain differences, so you don't need to adjust those with External mixer controls. Try Rocky first, it's probably the easiest to set up and use. It can also automatically adjust for your sound card and rig differences. If you are having so many problems, be sure to check your cables. I have had a couple of commercially made cables that were defective, with partial shorts between the various connections. I had trouble with I/Q balancing until I found they were bad.

It is supposed to work with any strong carrier, but it seems that it takes a super-strong signal to make it work correctly. To use it, inject a strong (>S9+30) carrier into the receiver antenna port. Tune so that it is off to one side of the pan picture. After a few seconds, all will be well. I have my XG3 connected to the aux ant jack on my K3 so that I can switch it in to do this little fix when necessary. It doesn't happen often, but sometimes NaP3 loses its mind and needs this treatment. Fiddling with the volume knobs on the Emu is fruitless, but this trick works perfectly in my shack.

Re: [Elecraft] CW Pitch Resolution
Hi John, I read that article too. Personally I think it is a lot of bunk. It assumes perfect hearing. Where ones sweet spot is depends upon his hearing and hearing degradation. The closest pitch to 432 Hz is 429.97 Hz on my K3. Some people's sweet spot may be 700 Hz-- since 432 Hz may be 20 db down from there! There was a link somebody posted a year or so ago. It could be used determined how much pitch difference one can detect. For most people is >3 Hz. For piano tuners and musicians with perfect pitch it is likely to be less. You can also try using the K3's fine tuning and tune in a carrier. The increase or decrease the K3's frequency by 3Hz and see if you can detect any change. Thus most won't perceive any difference between 429.97 and 432 Hz. If you can, than congratulations on your perfect pitch. 73 de Brian/K3KO On 10/13/2013 14:03, John Seney wrote: Hi Folks: The CW pitch resolution in my K3 seems to be 10 Hz per step.

Re: [Elecraft] CW Pitch Resolution
Assuming that you are talking about a KX3 or K3, they both tune in as little as 1Hz steps depending upon your RATE setting. So set your pitch to the closest 10 Hz, tune in a station and then adjust the tuning slightly as needed. If you think the other station might detect the tiny offset when you transmit, you and always rely on SPLIT or some combination of RIT/XIT to keep the xmit frequency the same. Personally, I work in SPLIT all the time so, after tuning in zero beat with the station I will call, I just tap A > B (or A=B) to put the transmit, B, VFO on that frequency and then I'm free to adjust the main tuning all I want without affecting the transmit frequency. Sometimes I do that just to listen to a different pitch in a long rag chew. But I'm usually making changes of 100 Hz or more when I do that. None of the filters are narrow enough to show any difference in less than 10 Hz tuning from the presumed center. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of John Seney Sent: Sunday, October 13, 2013 7:03 AM To: Elecraft Elecraft Subject: [Elecraft] CW Pitch Resolution Hi Folks: The CW pitch resolution in my K3 seems to be 10 Hz per step.

Re: [Elecraft] K3/0 tx audio problem
Paul: Assuming that you are using the Elecraft cables - the mic audio and PTT from the front panel Mic connector of the K3/0 is hard wired to the Mic mono and PTT In on the rear panel of the K3/0. The Elecraft cable then takes those signals to the AUX/MIC RJ-45 connector on the front panel of the Control RRC (refer to Fig 10, pg 13, K3 Remote Users Manual. Once the K3/0 and the K3/100 are talking any setting on the K3/100 is reflected on the K3/0 (don't make the mistake of thinking that the K3/0 can be set differently from the K3/100). So you need to set the K3/0 Mic (which is really controlling the K3/100) to be rPL.

[Elecraft] KX3-2M Pacificon demo notes
To those who stopped by to "kick the tires" on the KX3 with 2 meters -- Thanks for all the positive comments and suggestions. And thanks to Eric who, in something like two minutes, searched the vendor booths and scored a whip with an SMA connector for the demo. The firmware was in a pretty primitive state, but you got the idea. Someone asked why I had RIT and XIT both turned on, and I didn't get a chance to explain: it's because I haven't yet adjusted the VFO temperature-compensation algorithm on this band, so I had to manually correct the offset. Of course this won't be necessary when the code is finished. Given the enthusiasm for this addition to the KX3, which I may have underestimated, we're going to try to get the kinks out in a hurry so field testing can start. Among other things, we have to do another pass on the custom shield for the module, and design the final 2-meter antenna coax assembly, which has a UMC connector (Ultra Miniature Coaxial) at one end and an SMA at the other.

Re: [Elecraft] Interface and Ham Radio Deluxe
You can still reduce the audio from the soundcard program and, infact, this is what another bit of kit called the "PSK Meter" effectively does. The problem with just using the sound card output level is that once the slider gets down around 10 - where it will be if you are driving an electret input without an attenuator - it is quite difficult to adjust accurately. Since a mic input designed to work with a dynamic mic will be *another 20+ dB more sensitive* it is almost impossible to adjust between "no audio" and "overdriving the mic preamp" with the Windows mixer. Remember, typical audio levels are: Sound card at maximum: 1.5 V RMS Electet mic: 75mV RMS (26 dB below sound card) Dynamic mic: 5mV RMS (26 dB less than electret, *50 dB* less than maximum sound card level). 73, ...

Re: [Elecraft] auto-tuner needs more radio output to tune
Sorry, I probably missed some previous discussion, but I too have LDG auto tuners and one of them needed more than 5W to operate it (In fact that unit is dead at the moment, I changed the microprocessor and all was OK until I left it on the shelf for a few months and now it doesn't work anymore). However, I would have thought that the one designed to be used with the FT-817 should work with the KX3 as that Yaesu model is a 5W output rig as well. I can't say for certain, as I've never used a Z-11, but it would seem logical. Unless the Z-11 interfaces to the FT-817 via command lines other than just RF output? That can be a problem I know, as I also have an LDG KT-100 which I sometimes use with my Kenwood TS-2000X and that uses control lines from the Kenwood to get information that it needs in order to operate correctly. To be frank, I've not had much luck with auto tuners. They either seem to just be designed to match out the slight discrepancy between "50 ohm" outputs and supposedly resonant antennas, or they give up the ghost when you upgrade them (no offence meant to Elecraft, I've not used their tuners. In fact I decided to avoid using an intenal tuner again after recent experiences). Even well known designs have their limitations. I have Z-Matches from various manufacturers, L and T designs and various other stuff in storage here that I've tried and found wanting for various reasons. Some seem to be the ultimate dummy load - 50 ohm resistive input but little real output. Again, I am not talking about any Elecraft designs here, but if you look around the literature and dig under the hype, you begin to wonder what is really going on.

A better option is to use Line in/Line out on the PC and interface to an accessory socket that takes constant line levels. not lookied at the KX3 data inputs yet but if they are provided use them...

Hi Elecraft List, In anticipation of this morning's net, I powered up my KAT500, then my KPA500, and finally my K3. It came up in a state with an empty bright screen. Also I couldn't turn it off with the power button. I unplugged the K3, then plugged it back in. I restarted it in EE INIT mode. It appeared to work. I then powered it down with the power button, powered it back up, and reloaded the firmware. Again it appeared to work. I powered it down again , powered it back up, and reloaded the most recent configuration I saved. It resulted in the same faulty state of an empty bright screen and the power button wouldn't turn the K3 off. I repeated the entire sequence again from unplug to EE INIT to firmware reload to configuration reload using the next most recent configuration file. Same faulty state. Any idea what might have gone wrong? Any suggestions on how I should proceed?

I used for the first time the FM mode on 2M during an EOC Area Exercise this weekend. The K3 has the internal 2M transverter along with a 13 KHz FM filter in the main radio (VFO A) All were having much difficulty with my transmissions due to low audio output. RF out was not the issue with full quieting received by all. The deviation is at the factory setting of 5.0. Equalization is also untouched from the factory. It appears to be a flat line in Menu. Mic is a Heil Pro-Set Plus switched to Full Range. No issues with 2M SSB in VHF contests. Where do I begin to look to fix this FM Mode issue? 73, Bud W3LL w...@arrl.net __ 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

The problem with just using the sound card output level is that once the slider gets down around 10 - where it will be if you are driving an electret input without an attenuator - it is quite difficult to adjust accurately. Since a mic input designed to work with a dynamic mic will be *another 20+ dB more sensitive* it is almost impossible to adjust between "no audio" and "overdriving the mic preamp" with the Windows mixer. Remember, typical audio levels are: Sound card at maximum: 1.5 V RMS Electet mic: 75mV RMS (26 dB below sound card) Dynamic mic: 5mV RMS (26 dB less than electret, *50 dB* less than maximum sound card level). __ 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] SDR software for KX3?
Tom, I, too, am running the EMU0202. first thing you need to do is shft the receiver 8KHz. That makes the appearance a bit better. I also notice extraneous garbage on the display. It doesn't seem to interfere with the overall operation, so I live with it. Let me suggest that you not exceed 96 KHz sample bandwidth and then use the zoom feature to look at less than the sample rate. I haven't thought it through, but I was taught that you need to sample 2X the bandwidth. How we are able to use a bandwidth equal to the sample rate is something I really need to think about. But, I suspect that is contributing to some of the garbage on the screen. And, Elecraft suggests that you should stay at 48 KHz due to internal flatness of the radio's response, anyway. 73, Barry K3NDM - Original Message - From: "Tom" To: "Barry LaZar" , elecraft@mailman.qth.net Sent: Saturday, October 12, 2013 7:27:48 PM Subject: Re: [Elecraft] SDR software for KX3?

Re: [Elecraft] auto-tuner needs more radio output to tune
Julie, The KX3 power in CW and data modes is *not* limited to 5 watts (except when running it on internal batteries). I believe the solution to your problem can be found in the TUN PWR menu parameter - see page 40 of the manual. The power level set there will be transmitted when you do a TUNE (not an ATU TUNE). Yours is most likely set to NOR for which the TUNE power is the same as the power knob. TUNE will send a carrier (CW) no matter what mode the KX3 is set to. 73, Don W3FPR On 10/13/2013 1:01 PM, Julie Royster wrote: The LDG tech support folks say that a 5-watt KX3 output is not enough to trigger tuning by their product. We will eventually have the Elecraft tuner for KX3 when it ships, but for now what selection of modes & power etc on KX3 would give me the highest-wattage signal for the autotuner?

Re: [Elecraft] Elecraft Digest, Vol 114, Issue 22 - Re K3 Frozen on Power-up
Re K3 Frozen on Power-up Identical problem here when the K3-KAT-KPA were first put together: K3 froze when the KAT wasn't turned on first. Nothing worked until the cabling was disconnected, the K3 was turned on and off again, the cable was reconnected and the KAT turned on first. I don't know why either. I've tried two solutions: (1) Repeat this mantra once a day - "KAT goes on first." (2) More practical - the KAT does not need to be switched on and off if its supply power is switched on and off. When it feels its supply voltage coming (from a wall wart in my case), it comes on all by itself. So, I have a master 117 VAC power switch which switches the line to the K3's DC supply and to the KAT's supply (and most everything else.) When it is switched on, the KAT fires up instantly, before the K3 can (since it requires pressing the power button.) No problems since. For us liberal-arts types it's sometimes OK when a problem can be solved without necessarily being understood.

[Elecraft] S meter differences from K3 to P3
When operating I see a big difference between the noise floor and signal indications between the K3 meter and P3 display. For instance, on 80 meters tonight I see a noise floor of around S2-3 on the P3 and a signal peaking just over S9. At the same time the K3 meter is displaying a noise level of S9 and a signal level of 20 over S9. Is that a calibration error, a result of settings that I have selected - or just the way things are?

Well Jack, it could be a calibration error, but 1. Do you have the "K3 IF output" mod installed. It's one resistor, and it raises the 8MHz IF output to the P3. 2. I calibrated my S-Meter with my service monitor, S9 for 50uv in. Then I adjusted the P3 gain to give me -73dBm on the screen. 3. The P3 averages signals [you can set the sample size, 2 is the minimum], and my P3 never shows the same reading as my S-Meter on CW or SSB except when I'm doing RTTY or some other constant amplitude mode, and sometimes even those aren't exactly on what I expect them to be. 4. I don't think it's a problem for you, it's just inherent in the technology. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org __ 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] SSB Net
Computer programs can predict it. They can model it. They can study and analyze it endlessly. But propagation, especially above 10 MHz, will continue to confound anyone using those frequencies for a good many years to come - at the least. The only reliable indication that I have found are the beacons at 14.100. If you can hear one near where you are trying to communicate, you have something of a chance at success. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of David Guernsey Sent: Sunday, October 13, 2013 2:33 PM To: elecraft@mailman.qth.net Subject: [Elecraft] SSB Net Wish I could understand propagation. Last week all I could hear on 14.3035 was static. Today Phil was S9 into the Central Coast of CA, and I was able to check in with no problems at S7 to S9. I guess the answer is to try each week when I have the time. With my wife in a hospital 3 hrs away with a traumatic brain injury there are a lot of Sunday mornings when I do not get the chance, but I will keep trying when I can. 73 de Dave KJ6CBS __ 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] S meter differences from K3 to P3
The difference is likely due to any averaging you have dialed in. It was driving me nuts for a while until I figured out that the K3 S-meter seems to read the peak value of a signal while the P3 will show the averaged amplitude. I programmed "PEAK" onto one of the PN# buttons on the P3 and when I tap it the two amplitudes are in very good agreement with the default calibration. I have a new enough K3 (#4113) that it has the higher IF output designed for the P3. 73, Brian, K0DTJ __ 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] S meter differences from K3 to P3
There can be several factors at work, but the main one is that the effective bandwidth of the P3 is less than the K3. On an SSB signal, for example, the filter in the K3 passes the entire signal, and that is what the S-meter reads. However the P3 divides the signal into a nunber of frequency points on the display, each of which only receives a small slice of the total SSB signal. A similar thing happens with noise. However on a narrow-band signal like CW, the P3 and the K3 should agree, assuming the P3 and K3 are calibrated correctly and the K3's S-meter mode (CONFIG: SMTR MD) is set for "ABS" (so the S meter doesn't change when you switch the attenuator or preamp). There is a more complete explanation in the P3 Owner's Manual in the section "How to Set Up and Interpret the P3 Display."

Re: [Elecraft] P3 SteppIR Connection
You can theoretically connect the SteppIR "Y" cable on either side, but it is better to connect it between the PC and the P3 since there is less RS-232 traffic there than between the K3 and the P3.

Fred has given you excellent advice. I'll expand on he averaging issue. I always set up my P3 for the maximum averaging (20, I think), because it is best at separating signals from noise. But most of us set the S-meter for peak reading. For this reason, there will always be a lot of difference between the peak value of the signal and the average (except for keydown modes like PSK, RTTY, JT65). The P3 can, however, be set to read peaks, and both displays are useful, so I assign the toggle for the peak function to a soft key. Once you have done the calibration that Fred has described (see the manual), the peak mode of the P3 and the peak mode of the S-meter should agree. 73, Jim K9YC __ 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

A similar thing happens with noise. Yes. There's also a setting in the P3 menu to automatically adjust the vertical gain of the display to compensate for the variable width of those slices (FFT guys call them "bins"). There's also the uncertainty principle as applied to frequency and time. Because frequency and time are the inverse of each other, the product of frequency resolution and time resolution is a constant. It is impossible to accurately know BOTH frequency and time. We can adjust for one or the other, but always at the expense of the other. 73, Jim K9YC __ 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
