[Elecraft] (Elecraft) CAL PLL
WOW!!! This building project has been fantastic. I've certainly learned or relearned heaps... Thanks to Elecraft and all those who have helped me along the way, I am extremely happy with results. Everything is now complete and all seems to be working well but I can't recall if I did CAL PLL after resetting c22 in my final alignment. If I repeat CAL PLL on my K2, does that mean that I must redo CAL FIL and all filter alignments again? I did filter alignments using a noise generator and Spectrogram and the graphs appear much as the examples in Don's W3FPR alignment instructions, but I'm not too sure exactly what I am looking for In Spectrogram. I simply tried to get graphs to be as similiar as possible to the examples. Apologies for dumb question but, Is there something special I should be looking for? Something to be minimised or maximised in the graphs? If I do CAL PLL and CAL FIL again, does that mean I should also redo KAT100 settings? I've also built the cable between k2 K102 and PC and all tests ok. I've not made any on air contacts yet with this rig other than into a dummy load and some testing of my antenna with KAT100. I wanted to get alignments done as well as possible first. Maybe I'll get my feet wet this weekend!!! :-) 73, Kev VK5KS K2 #7552, KSB2, K102, KAT100-1 __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] Video online: K3/P3 monitoring K1N JA Pileup
I made this video today while monitoring K1N working a JA pileup. It demonstrates the value of the P3 panadapter in finding the station the DX is currently working and determining if the DX station is using any type of tuning pattern from QSO to QSO. Freq: 24.898 Mhz CW at 2345 gmt Feb 5, 2015. The pileup was huge and took up about 20 Khz of the band, with too many callers to really allow a decent rate. Both K1N and the JA stations were loud at my qth in northern Utah. The JA pileup was fortunately very well behaved, always standing by while K1N completed each QSO, and that made it rather easy to find the station he was working. Follow the link and take a look and listen: https://vimeo.com/118876333 Don, N5LZ __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] (Elecraft) CAL PLL
Kev, Great about your K2 completion. For doing CAL PLL again, check the accuracy of your K2's frequency. Do that on the highest frequency you can receive a known frequency signal - as long as that frequency is in the 17 meter band or lower. If the frequency is within 20 Hz of the correct dial reading, don't bother. OTOH, if the frequency is not correct, then yes, setting C22, followed by CAL PLL and then CAL FIL should correct it. See the procedure for setting C22 on my website www.w3fpr.com. If the known frequency signal is not an AM station, things get a little more complicated in determining the correct tuning of that station - send me a private email and I can help you with the correct tuning. Bottom line -- if your frequency readout is not correct, then you will have to go through the full process of setting C22 followed by CAL PLL and CAL FIL within a short period of time. The 4 MHz reference oscillator is only controlled by the 4 MHz crystal and can drift over time. The exact frequency of that oscillator is not critical for normal operation, it is only a clock for the MCU. However, before running CAL PLL and CAL FIL, it should be set accurately if you are to achieve correct dial frequency readout -- so do the entire process in one sitting so the 4 MHz oscillator does not drift substantially during the process of setting C22, running CAL PLL and CAL FIL. 73, Don W3FPR On 2/5/2015 10:51 PM, Kevin Schache wrote: WOW!!!

[Elecraft] KPA3 failure?
My K3/100 #4275 has suddenly stopped making 100 watts, and is now making 10-20 on 160-20 meters, and 45-50 on 17-10 meters , even though the power control says it should be making 99 watts. On the way to its current state, it cycled once through reduced power and back to full power after a band change, so I suspect something was in the process of failing. Any ideas where to start troubleshooting, or is this something that warrants a trip back to the mother ship? Addendum: In further testing, with power turned below 10 watts to disable the KPA3, I'm now seeing less than 1 watt on 160, 8 on 80, 8 on 40 and 11-13 on 20-10. Turning the power back up to 100 watts, I now have 20 watts on 160, 35 on 80, 25 on 40, 50 on 20, 85 on 15 and 100 on 10m.

Re: [Elecraft] CW for those with Poor Hearing
My hearing sensitivity in my right ear is much lower than in my left ear and, in addition, I have a constant ringing (Tinnitus) which I've become accustomed to so it's less bothersome than it sounds. I find lower tones markedly more comfortable. I only operate 100% CW and I always use headphones. I've tried many different brands,including some of those modern earbud thingys the young folks jam into their ears but that's about the most annoying thing I've ever experienced. For years now,I've been using the David Clark model 10-S-DC listen only stereo headset. These are aviation-grade but non-TSOd and are meant for passengers who want to listen to their personal electronics as well as connect into the aircraft intercom system. These have excellent clarity and independent volume controls which complements DXing with my KX3's Dual Watch function. The clamping pressure is LESS than the standard aviation grade DCs but enough to work just great as a passive noise reduction feature. The sensitivity (loudness) of this consumer model clearly exceeds my original aviation DCs. So that's how I've solved my problem and I don't even think about it anymore as I operate. 73, Stan WB2LQF On Thu, Feb 05, 2015 at 06:55 PM, Bob Gibson via Elecraft wrote: Same way here..

Re: [Elecraft] CW for those with Poor Hearing
Harry, I heartily recommend the Bose QC-15 headphones. They have a marvelous ability to cancel out almost all background noise at the flip of a switch, at least 50%. It helps to greatly reduce noises like fan noise, room acoustics and TV from others in the house. Far more clear than listening to even a good quality speaker when it comes to hearing CW well. It is a headphone but allows replacement cords to be attached and within the design, unbeknownst to most users, is a mic plug which also allows for a microphone. You can't easily get such a mic plug from Bose, they reserve that for their overpriced Aircraft communications headsets. You can though buy an after-market microphone attachment which lets you hear talk.

Re: [Elecraft] CW for those with Poor Hearing
I found the Headset Buddy to be a pretty poor excuse for a mike. Communication fidelity was terrible (and i'm not an ESSB fan), the mike boom was too weak and left it dangling and the cord had the left and right headphones reversed from normal which drove me nuts working split. I contacted their tech support and they sent another which was no better.

Re: [Elecraft] PX3 spikes every 12KHz
I had a couple of other replies off list that confirmed that this is perfectly normal, and usually band noise covers these spurs up. Apparently they are from the high efficiency switching voltage regulators on the 5V and 3.3V lines in the PX3. I suspected that, but though mine was perhaps poorly filtered or faulty, but apparently this is normal. I don't see it being a problem on HF, but could be annoying on transverter bands where band noise is much lower. Maybe once out of warranty a mod to using linear regulators could be worthwhile. 73 David Anderson GM4JJJ On 5 Feb 2015, at 10:10, David Anderson gm4...@yahoo.co.uk wrote: If you have the PX3 completely unplugged do you see those spike at 12KHz spacing?

Now plug in the RX I/Q lead to PX3 and on 14MHz with preamp on and a dummy load, with span at 50kHz I see noise floor rises to -130dBm, spikes now at -112dBm but they have moved in frequency slightly away from the centre and are space 12kHz apart.

Re: [Elecraft] Using K3 with Skimmer
Pete - I use Skimmer with my K3. My SDR is a Softrock. Yes, it works on all bands when setup properly. I use LP Bridge to create the virtual COM ports to interface Skimmer and DXLab or N1MM+ simultaneously with the K3. I highly recommend LP Bridge if you're not already using it. The Skimmer set up with LP Pan (used to have one) like that for Softrock is a bit quirky. I know just the dialog that you're having trouble understanding. Never quite got that either. But point and click tuning and easy QSYing and being able to see the whole pile are great tools. If you have trouble finding where the DX is calling, use the 599 feature with verified calls only selected. If the pile is too spread out to be seen on Skimmer using one monitor, set up a second monitor above the first, extend the desktop and then pull the top edge of the Skimmer window onto the upper monitor to increase the frequency range seen on Skimmer. It's rare to need to do this, but it'll let you see the DX and the entire pile. Helped me work K1N through a huge pile on 10M CW yesterday. I have found Larry, N8LP to be very approachable and very helpful. I expect he would be prepared to discuss the Skimmer setup. There is also a treasure trove of info on the LP Pan website.

Re: [Elecraft] PX3 Amplitude calibration
I think Alan, NA1L, posted some words similar to these to the reflector some time ago about why the PX3 and KX3 signal strengths don't agree at times. They probably apply to your question. 1. The PX3's LvL Mode is dBm. The dBm display is a quantitative display of power (in decibels relative to a milliwatt) at the KX3's antenna. That signal has an absolute power and thus isn't, nor should it be, affected by the KX3's signal processing preamplifier or attenuator. Therefore, the PX3 automatically compensates for the KX3's preamplifier or attenuator when the display is dBm. Changing the preamplifier and attenuator will not change the signal displayed on the PX3. Meanwhile, if the KX3's SMTR MD menu is nor, changing the preamplifier and attenuator will change the signal displayed on the KX3. 2. The PX3's LvL Mode is S-units. When the PX3 shows S-units, it has the same behavior as the KX3's S-meter and increases when the preamplifier is on and decreases when the attenuator is on. Note that for most bands the preamplifier must be set at +20 dB for a 50 microvolt signal to display S9. 3. The signal level on the KX3 and PX3 depends on their respective effective bandwidths. In the KX3 the bandwidth is set by the pass band tuning control (PBT I/II). In the KX3 the S-meter gives you a measure of the signal within the KX3 bandwidth. In the PX3 the effective bandwidth is approximately the span divided by 450 (there are 450 pixels displaying signals across the PX3 display). In the PX3 each pixel gives you a measure of the signal within the effective bandwidth of the pixel. If the two bandwidths are different, the KX3 and PX3 signal displays will be different. This will particularly be evident with wideband signals such as SSB. Even when the PX3 span is 200 kHz its effective bandwidth per pixel is 440 Hz and it does not contain the full signal that is seen on the KX3 S-meter. I agree with Phil. In essence each display serves a different purpose. The KX3 S-meter shows you the signal strength of the one signal within its passband and the PX3 shows you the relative strengths of a number of signals shown in its span.

Re: [Elecraft] PX3 Amplitude calibration
Hi Fred, I understand the reason that the S-meter and panadapter don't agree. I was hoping that for a given signal level input, with spans set the same, that the PX3 signal level and noise floor would be in agreement with that being displayed by the P3. It's not a big deal, but I was surprised by the lack of an amplitude adjustment. The reason I care about the level on the panadapter is that it gives me a quick sense of band noise levels at a glance. We have some local broadband white noise sources around here, and I can get a quick sense of whether they are giving me grief or not. I still do wonder though if an amplitude calibration or level adjustment could be implemented, as it is in the P3. If not, I'll continue to make band noise floor assessments based upon the K3/P3. (I'm clearly spoiled by the P3) 73, Dale WA8SRA I think Alan, NA1L, posted some words similar to these to the reflector some time ago about why the PX3 and KX3 signal strengths don't agree at times.

[Elecraft] Using K3 with CW Skimmer
The LP-PAN offset is nominal 6000 Hz, but it typically runs at about 6100-6150 Hz. This value is entered in the NaP3 Global Offset box as a negative value, ie. -6000. The LP-PAN LO is 32836/4=8209 kHz. The K3 IF center is nominal 8215 kHz, a difference of 6000 Hz. The Skimmer Audio IF, Hz value can be calculated from the following formula on our CW Skimmer help page... *K3 CW Sidetone Pitch + LP-PAN Global Offset = Audio IF, Hz * For example… 600 + (-6000) = -5400 You can walk it in from there. ALso, unlike NaP3, Skimmer does not adjust for filter offsets or DSP shift settings on the K3, so it is best to do this with the Shift/Width controls centered. The value will vary from filter to filter unless all your CW filters are 8-pole. 73, Larry N8LP On 2/5/2015 11:25 AM, elecraft-requ...@mailman.qth.net wrote: Date: Thu, 5 Feb 2015 07:46:42 + From: Ken Chandlerg0...@sky.com To: iain macdonnell - N6MLa...@dseven.org Cc: Elecraft Reflectorelecraft@mailman.qth.net Subject: Re: [Elecraft] Using K3 with CW Skimmer Message-ID:51ccb0f8-7714-4bc6-991d-b71d03272...@sky.com Content-Type: text/plain; charset=us-ascii I'm seeing differently too.

Re: [Elecraft] CW for those with Poor Hearing
Henry, Your real answer depends on your particular hearing loss, so no one else can say what your particular desired pitch can be. I suggest you experiment with different pitches in real time CW QSOs. Tune the station to the pitch that you can copy best - then figure out what that audio frequency is. You can play the CW through an audio spectrum analyzer to determine the pitch that you hear best. One such analyzer is Spectrogram, and the 2 freeware versions (5.71 and 16) can be downloaded from my website www.w3fpr.com. Look for the links near the bottom of the opening page. These are local copies of the Spectrogram files that have been virus scanned numerous times. I hear reports that some sources of Spectrogram contain bad stuff, but these are clean copies.

There are several types of hearing loss. That which comes with old age is a loss of high frequencies; what you appear to have is likely the result of excessive noise exposure, and can be anything from a big hole in the middle of frequency response to massive loss of highs to ringing. If your loss is mostly highs, it can be PARTIALLY compensated using RXEQ. Simply turn down the lower bands and turn up the higher ones. If it's the ringing that drives you nuts, try setting the CW RX pitch lower. Play with it and see what works for you.

My K3/100 #4275 has suddenly stopped making 100 watts, and is now making 10-20 on 160-20 meters, and 45-50 on 17-10 meters , even though the power control says it should be making 99 watts.

Re: [Elecraft] PF1 and PF2 Programming Question
Absolutely. Go into the K3 Utility on the Command Tester/K3 Macros tab. Click the 'Edit Macros' button. Type a label for the macro in the Macro Label field. In the Macro Commands, use the command TE followed by a numerical value for each EQ setting (i.e. 50, 100, 200, 400...etc). For example, TE-12-10-06-02+00+06+08+10; This will set 50 Hz to -12db, 100 Hz to -10db, 200 Hz to -06db... etc. Don't forget to enter the ; at the end. Save your macros and then send them to the K3 using the 'Write Macros 1-8 to K3' button. Then go into the K3 CONFIG menu and select 'MACRO 1' with the VFO B knob. Then hold PF1 down for a second or two and it will assign macro 1 to PF1. Then press 2 on the keypad to switch to MACRO 2. Hold PF2 and it will assign macro 2 to PF2. If you want, you can also specify mic gain and compression settings along with the TX EQ commands. MG014; will set mic gain to 14 and CP12; will set compression to 12. You enter it in the macro command with the EQ settings as follows: MG014;CP012;TE-12-10...+08+10; 73 Mike - KI0HA On 2/5/2015 04:27, Mike VE3YF wrote: Hi: I haven't tried my hand at doing some programming yet, but wondering if it is possible to set the PF1 and PF2 for TX EQ Audio settings.

However 1 question comes to mind, in my situation I have 2 different mics (Headset with HC-5 and the other mic is a PR40) and they require the FP-L and FP-H and I see no macro commands that set the Mic Gain Range. I don't see anything right off, but is it possible to make the Macro to incliude the settings of Mic Sel (Source, Mic Gain Range and Bias) Any idea's, I guess worst case scenario, I could reconfig both both TX EQ settings to work with both mics using either the High or Low Range.

Re: [Elecraft] PX3 spikes every 12KHz
If you have the PX3 completely unplugged do you see those spike at 12KHz spacing? They are very prominent then. Tried the following: REF level -145 SCALE 80 SPAN 50 Everything plugged in apart from the RX I/Q lead at the PX3 end: Noise floor about -138dBm 2 spikes either side either side of centre -116dBm at 14kHz intervals. Now plug in the RX I/Q lead to PX3 and on 14MHz with preamp on and a dummy load, with span at 50kHz I see noise floor rises to -130dBm, spikes now at -112dBm but they have moved in frequency slightly away from the centre and are space 12kHz apart. Putting Average on helps to allow the measurement, but the spikes are obvious even with averaging off. They are obviously internally generated in the PX3 as they do not change as frequency of radio is changed. I can't believe that it is correct that there should be such visible artefact nearly 20dB above the noise floor. Any suggestions? - I did the OSB calibration procedure and that worked fine. I checked the cables are well seated, and have checked the tightness of the connector nuts on the PX3. Before I contact Elecraft, could someone check their PX3 in the same way as I described and let me know if they see the same effect please. 73 David Anderson GM4JJJ On 5 Feb 2015, at 00:07, Phil Wheeler w...@socal.rr.com wrote: Make sure your cables are well seated.

With the new Win4K3 Suite integration with CW Skimmer, you can click on the call signs list in CW Skimmer and have VFO B QSY to the call sign of the op being worked by K1N. This could just be the ticket to help you snag that CW contact! Also, the Scope window now has macros at the base of the scope window. For example I am using 10 macros as follows: 1: Spot - SWT42; 2: AB - SWT13; 3: A/B - SWT11; 4: Split - SWH13; 5: UP 5 for VFO B - UPB7; next row: 6: M1 - SWT21; 7: M2 - SWT31; 8: M3 - SWT35; 9: M4 - SWT39; 10: DN 5 --- DNB7; P.S.

Re: [Elecraft] CW for those with Poor Hearing
Jim has helped me in a number of ways, both RXEQ and getting good TX audio from my K3. I'm pretty much deaf above 1200 Hz, lots of sudden, very loud noises in my bulletproof and immortal period 50 years ago. Jim's RXEQ suggestion gave me about 30 dB of higher frequency boost ... turn down the lows, raise the highs, and turn up the AF Gain. I generally run mine around 12 o'clock, much above that and distortion gets really bad. I don't know if that's in my headset [Heil ProSet from Elecraft], or clipping in the audio amp. 30 dB is only about a third of my hearing loss above 1200 Hz, but it does still make a BIG difference. I found my sweet spot for pitch just by experimentation with the pitch control. On sideband ... which you won't find me on much, very hard copy ... at DSP BW around 2.1 or a little less, I shift it down. For RTTY, I use the 915 Hz setting in the K3 and MMTTY. Many years ago, while a high school senior with a part-time relief op job at a coastal marine station, the OT's taught me that when the noise on the Holy Frequency was really bad, lay the cans on the desk. Somehow, this lowers the noise and not the signal. The VA has given me some very good hearing aids, they don'w work under the headphones, but using them with the headphones on the desk does often improve the SNR of very weak signals.

[Elecraft] e: Using K3 with CW Skimmer
Pete, Joe and all: I am not running CW Skimmer so this post is a little OT, but I do run the LP-Pan with MAP65 (JT65B). For good info go to: http://www.telepostinc.com/LP-PAN.html#faq Scroll down till you see LP-PAN Manuals and chose the version for your unit serial number. e.g. S/N 514-799 page-24 has the Circuit description which ought to help understand the LP-Pan. Page 26 shows the schematic. For the K3 1st IF=8.215 MHz, the LP-Pan LO =32.836 MHz which counts down to 8.209 MHz which imparts a 6-KHz shift to suppress LO leakage. I had to request the original xtal=32.860 MHz to correct this as it shifted my MAP65 frequency too far to be correctable by the sw. That does leave me a center carrier artifact but I do not operate there so it doesn't matter. I did have to swap I/Q to have sw operate properly. Actual frequency of the xtal LO may be off exact frequency a little (maybe a couple hundred Hz) but that should not affect most users. If you are curious how I am using the LP-Pan with my K3, go to: http://www.kl7uw.com/LINRAD.htm This also has the instructions on how I added IF output from my KRX3 sub-receiver. near the top are links to LP-Pan website and manual.

I don't see it in wider settings. http://s1295.photobucket.com/user/KA1J/media/P3_zps5f68799b.jpg.html or a shorter URL is http://tinyurl.com/kkne9ww Any idea how to get this to display evenly?
