[Elecraft] [K3] Toggle macros
Apologies if this is 'yesterday's news'...
When I'm SPing in a contest with the 2nd receiver in the right ear (A-AB) I
like to be able to switch quickly to sub in both ears (AB-AB); often it
makes it easier to copy a weaker signal.
I've been doing this with 2 macros to switch the L-MIX-R menu item, one
allocated to M4 TAP and the other to M4 HOLD. After reading the recent posts
on the K3 Triple Macro ('self modifying code') for cycling power levels I
realised I should be able to set up the audio mixing macro on just one
button as a true toggle switch, and the following 2 macros both allocated to
M4 TAP does just that and now releases the M4 HOLD for another macro.
MACRO 5 AB AB MN111;MP003;MN110;SWT29;SWT39;SWT14;
MACRO 6 A ABMN111;MP001;MN110;SWT27;SWT39;SWT14;
Thanks to whoever thought of all this, it's pretty neat. The first 2 fields
(MN111;MP003;etc) switch the L-MIX-R and were originally allocated to tap
and hold separately; the other fields reset the macro as in the 'Triple
Macro' examples.
As an aside, it would be great to be able to comment the macros (in K3
Utility?) especially when they're a bit involved like this; I've not found
this is possible. Presumably this won't work unless the 'comments' are
stored in the K3's EEPROMwith the inevitable space issues?
73,
Stewart, GW0ETF

Re: [Elecraft] Buying a K3 in the UK?
A few years back I bought a couple of KB9YIG's little SDR receiver kits (one still in use as a panadapter for my K3..).

[Elecraft] [K3] Temporary loss of rx/tx
Twice last night I experienced a short lived loss of (rf) power. Everything just went very quiet on receive and there was no rf output either. It was the same on both receivers, all antenna inputs etc and there were no error messages flagged. Makes me suspect the 49MHz reference on the KREF3 board, or the tmp connectors. I've poked around and can't get any repeat so I'm wondering if there would be any other source of such a fault. Many moons ago I soldered in place the oscillator module on that board as it was a bit wobbly in the socket and I decided I wouldn't be upgrading to the high stab version; never mis-behaved previously. Perhaps dirty contacts, but why no error messages?? 73, Stewart, GW0ETF -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Temporary-loss-of-rx-tx-tp7277628p7277628.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] [K3] Aliases in Softrock panadapter display
Thanks for the replies so far. However none tell me anything new... There seems two ways to sync K3 and software (NaP3 in this case):- 1/ Set Global Offset to zero and and the SDR LO frequency to what it actually is, ~8192 Khz 2/ What you all seem to do is set SDR LO frequency to the K3 IF centre, ~8215 Khz and then fiddle about with the Global Offset to get the radio and software to sync. Yes, I can do either but in both cases the SDR LO=0Hz centre point will be offset from the tuned signal by approx 23 Khz. This means that if the tuned signal is centred, the extreme ~23 Khz of the side opposite the SDR Local Oscillator will be in the alias region. Try injecting a signal and tuning it across the display toward this region. As it crosses this point it dies away to be replaced I assume by an alias coming in from the opposite side (which is not visible). If the display was chopped off here as in Rocky, or indicated by a change in background colour that would be better.

Re: [Elecraft] K3 - Choice of filters in KRX3
Robby, I'm almost a 100% cw contester with a single antenna and I find SO2V of limited but worthwhile use when run rate is dropping off. I always use full break-in so when listening to the 2nd rx in the headphones you only hear signals between your sent characters. This chopping makes it impossible to copy callsigns so you have to have pick this up during gaps in sending; you can then drop the call into the VFO B window with the '/' key (N1MM) to see if it's a dupe. If it's not then at a suitable juncture simply press the 'Pause' button to swap VFos and focus, and hit Enter (ESM!) to send your call, work 'em and then 'Pause' to move back to your run frequency (assuming someone hasn't jumped on it while you've been away!). I normally don't use cluster assistance; if I did SO2V would really be neat as you could simply hotkey VFO B to each spot and work them between running Qs. This is how I understand the use of SO2V so if anyone has diferent/better ideas I'd be interested to hear them. 73, Stewart, GW0ETF Robby.VY2SS wrote: Stewart, I have never tried SO2V operating but I would be interested in hearing more about it since I seem to have the hardware for it. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Choice-of-filters-in-KRX3-tp6932305p6954534.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] K3 Strange Problem
Don't forget the 'quality of PL259 plugs' issue that's has been mentioned on here before. A while ago I nearly pulled my amp apart to check the input relay to see if that was the cause of my intermittent 'Hi SWR' and no rx signal problem. Problem was an intermittent mating of the PL259 centre pin in the socket barrel; either the pin was slightly undersize or the barrel had previously been expanded by a PL259 with too much solder on the pin. 73, Stewart, GW0ETF Rick Bates wrote: Good catch Don.

[Elecraft] K3 - Choice of filters in KRX3
When I bought the 2nd receiver after it first came out I matched the main rx with an 8-pole 250 Hz roofing filter. After several years now of SO2V contesting and dx pile-ups I've never had the 2nd receiver wound down anywhere near the point where this filter would be switched in. So I'm wondering whether to liquidate this particular valuable little asset and invest in something more useful...such as antenna hardware. Before I do perhaps others could say how they think the 2nd rx should be populated filter-wise, which presumably will vary with operating mode. I don't tend to do the 'second op with separate headphones tuning the 2nd vfo' scenario which is I assume where a full filter complement would be useful.

[Elecraft] Deoxit contact cleaner for the frugal

Re: [Elecraft] Deoxit contact cleaner for the frugal
Bill, I started with Deoxit 5 months ago. Until then I was used to removing the front panel every few months and cleaning the contacts with alcohol to stop the recurring error messages. No error messages since then though have had the odd loss of pll lock while tuning which may or may not be poor contact related. It's the old conundrum of proving a negative but so far so good.

Re: [Elecraft] K3 err msgs on powr up?
I have K3 #145 and this problem has plagued me plenty in the past. I now know it *is* a problem with the FP connections as Wayne describes. I've more or less stopped it by using Deoxit on the pins; clearly there is an issue with oxidation(?) of the pin surfaces. BTW, Jorge states the radio performs normally even when the errors appear.

[Elecraft] K3 - Cross mode data
Folks, Spurred on by a renewed commitment to the monthly RSGB 80m data contests where you work both rtty and psk31 I've belatedly sorted out SO2V with 2 digi windows in N1MM using one soundcard and afsk/data A on the K3. You more or less maximise your score by working 50:50 psk31/rtty so thought it might be neat to have one window set for psk and one for rtty and switch between in N1MM but when that's done vfoB gets set to the data mode of vfoA which screws things up ofcourse. To simplify things I've just checked the K3 standalone and it seems you can't have each vfo set to different modes within DATA and just wanted to confirm that this is indeed the case. Certainly a minority operating style and I could always use data A for rtty but that would preclude the use of the dual p/b filter etc. Even if it were possible I haven't even thought about whether split would work, about which much has been previously written... 73, Stewart Rolfe, GW0ETF -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Cross-mode-data-tp6453060p6453060.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] [K3] multiple error messages on start-up
John, I consider myself a bit of an expert in the multiple error messages on start-up front! (do a search here on my callsign...) After many months of headscratching, removing/replacing modules and even replacing chips, it turns out in my case to be poor contacts in some of the pins of the front panel connectors. My K3 #145 is not in a particularly 'hostile' environment but this will still crop up occasionally; removing the front panel and a clean of the connectors with isopropanol always cures it long term. I get multiple errors and the reason you're only getting 12W out will almost certainly be due an ERR PA1 in your list; nothing wrong with the PA module, just the software thinking it's not there. Good luck!

Re: [Elecraft] Fwd: K3 Failed DSP Firmware Download
In the 3 years of running my K3 I can only remember once having to do a forced reload and it was completely straightforward.don't understand the stress this seems to generate.

[Elecraft] k3 - AFX effectiveness
Been having a fresh look at the AFX in view of the recent postings about pulling out callsigns from pile-ups. It's been set to BIN for a long time now and I remember this being quite effective at giving some spatial separation to signals differing slightly in frequency when using stereo headphones. However, now the effect seems to be much less noticeable than I remember, and this with the same headphones and settings; turning AFX on and off gives a definite change, but the spatial effect seems to much less. I wonder how others see the effectiveness of AFX and particularly the BIN setting. Pretty sure I haven't done anything to alter this; maybe I'll dig out one of the much earlier firmware versions and see if it's maybe altered over software upgrades. 73, Stewart Rolfe, GW0ETF (K3 #145) -- View this message in context: http://elecraft.365791.n2.nabble.com/k3-AFX-effectiveness-tp5811754p5811754.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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
[Elecraft] Love/Hate your K3
Three hours into cqww the output power on my K3 started fluctuating wildly and then went to zero. It happened last week too but recovered but this time it looked final; after significant preparations for the contest and in the middle of a freezing night I wasn't a happy person. I'd sort of resigned myself to waiting a few hours and then driving 35 miles to hopefully borrow a K3 from a friend who wouldn't be doing the contest; first though I'd quickly check the reflector and to my delight up popped a message describing this very fault, caused by the TMP cable coming loose from the J7 connector on the KREF3 board (thanks N3CAQ..!). Off came the lid to reveal a well seated cable but a nudge on J7 with a pen brought the rf back to life! Mightily relieved I carried on and things were fine for a couple of hours until the same thing happened; this time I removed the 2nd receiver and took out the cable to test it and sure enough the meter across the centre pins showed intermittent continuitygently flexing the cable caused the connection to come and go. Interested to speculate how long the cable has been faulty; this ancient model (#145) has definitely showed power fluctuations in the past on occasion but I've assumed a software source (can't explain it..? must be software..!) so maybe it's been like it from new, don't know. The good news was I remembered having a spare new TMP cable left over from the KRX3 fitting which I used and all was then back to normality. This now begs the question of getting replacement TMP cables which I will pose to Aptos since I assume they are custom made and I can't imagine a non-specialised crimping tool doing the job. Moral of this tale is check the reflector first, and watch your connections; the few problems I've had over the years (including random error messages) have all been traced to less than perfect contacts of one sort or another. CQWW was excellent though I am considering claiming for an hours worth of points from Aptos ;-) Thanks to all those calls familiar from here for the Qs on 40m - I was sosb low power.

Re: [Elecraft] APF For K3
Be aware though that the DSP 'switches off' the EQ once you get to 100Hz and below bandwidth.

Re: [Elecraft] WTB SoftRock SDR
I do hope you find one Val because as a cheap alternative to a P3 it's excellent. I've had one for a while but the PC I was running PowerSDR/IF on was rather old and clunky and it didn't run very well; it did have an internal PCI M-Audio D66 soundcard though so it stayed something of a novelty rather than a useful tool. But the other week just for grins I thought I'd see what would happen if I tried my Samsung NC10 netbook with it's internal Realtek HD soundcard and to my surprise found it works really well, giving me up to about 90kHz audio bandwidth with no obvious spurs or images - and PSDR/IF runs really well too. Can't seem to find any specs for these soundcards so I'm not sure why it appears to work so well. So my shack has now been re-configured around the netbook and LP-Bridge; PSDR/IF sits on the netbook screen and my logger(s) on a second LCD monitor behind it. Used it in a contest for the first time last weekend and found it really useful, particularly for picking off stations off the second vfo. 73, Stewart, GW0ETF Val-12 wrote: I'm looking for SoftRock RX but it is not available at KB9YIG.

Re: [Elecraft] [K3] - Odd SWR readings ANT1 v ANT2

However if I turn on the ATU and 'tune' it to match to an antenna and then go back and check bypass into the dummy load I get a high reading again.

Re: [Elecraft] K3 IO1 Error Message
Chris, Random error messages on boot up still plague me frequently. Normally I get a whole series of them beginning with BP3 usually but they can vary. With me Sub always works but ATU and 100w module doesn't until I've sorted it by repeated power up cycles or just leaving on for a while and then turning off and on. One time recently it took a good hour of trying before it turned on correctly I've never been able to figure out any logic to this; no connection with temperature or the radio being moved, different firmware etc. The most recent official release dealt with 'bus timing issues causing random error messages on switch on..' but no real difference here and I'm pretty convinced it's software and not hardware or seating problems, as when I've got rid of the errors the radio works perfectly. Just when I think the problem's here to stay and decide it's time to tackle the support guys again the radio starts to behave and I don't bother but it's quite frustrating when it's in a I'm not going to start up properly mood. 73, Stewart, GW0ETF -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-IO1-Error-Message-tp5148110p5149863.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] [K3] kit building or buy ready for use
Volker, It only makes sense to buy factory built if you buy the K3 with all the possible modules fitted otherwise you will be dis-assembling the radio to fit other modules at some later date. A design philosophy of the K3 is being able to buy the basic unit and upgrade as you can afford it or as the dollar/euro/sterling rate becomes more favourable! Field upgrading is just an extension of the kit rationale. I bought #145 as a kit back in July 2007 and had to wait many months for the second receiver which required a significant refit. Being an early unit I have fitted several uprades and have had to replace a faulty main dsp board too; knowing how it all went together in the first place made all this straightforward and easy to do. So if you have the time and don't have visual or physical impairment it's not a problem at all. There's the extra security of knowing that the finished unit has been tested in Aptos but even if/when a problem does arise you will be talked through it step by step and receive board swaps as necessary in a manner probably unique to Elecraft. My DSP board problem was a minor one linked to the second rx and was sorted quickly and efficiently but it did require me to swap out a couple of boards which were sent from Aptos. We are after all 'Radio Amateurs' so we shouldn't really have a problem with screwdrivers and ESD mats, should we?? 73, Stewart Rolfe, GW0ETF quot;Volker Wächterquot; wrote: Hello @ all, I do not know what most of you did.

Re: [Elecraft] Thinking about KXR3
Think you have that pretty much sorted Jim. I have an 8 pole 250Hz roofing filter in my 2nd rx as I thought it would be good for 'mult-hunting' during contests but in reality hardly ever use it. Not sure how important it would be to insist on a matched 2.7KHz filter either. Because the bandwidth is so high you can simply make the small 'centre frequency' adjustments in software without affecting performance hardly at all; obviously more of an issue for the narrower filters...that's my understanding anyway.

In the remote chance I ever become proficient enough to be a Fox the sub would be tuned to my transmit freq to listen for potential QRM while the main would be trying to separate the hounds.

Re: [Elecraft] [K3] K3: killing RX key clicks
My take is that in the extreme cw is an AM signal modulated by a pure square wave and as such prduces infinite odd order harmonics which will appear as sidebands/clicks. Filtering reduces the extent of the sidebands and smooths the square wave shape particularly rise and fall times but you will still have sidebands equivalent to 7th or 9th harmonics..? This would represent the ideal and you would have to be very close to the signal to hear the sideband energy - a bit of work on the calculator will tell you where the 7th or 9th harmonics would appear for a string of dits depending on the keying speed etc. But I'm convinced that most bad clicks are actually a result of spurious switching spikes at the 'corners', often at the trailing edge and can produce sideband energy *way* out from the fundamental. This is nothing to do with the inherent physics of the cw signal and as such is curable. 73, Stewart Rolfe, GW0ETF Ron D'Eau Claire wrote: It's basic physics, Jim.

Re: [Elecraft] K3 in the CQWW contest
For a couple of years now, since getting K3 #145, I've had the impression that activity in the big contests like CQWW has been dropping off because now I don't seem to have problems finding a run frequency. Obviously it's all down to the K3:-) Ref key clicks.(bear with me!) I have relations who fish langoustine off north west Scotland in an area used as a 'testing site' for the Royal Navy nuclear submarine fleet. Here they analyse the sound spectrum emitted by new or serviced engines so they can adjust the onboard system which emits anti-phase sound to cancel the engine noise and so make them silent to other vessels nearby. So I wonder if it might be feasible to develop a system on the K3 to use the 2nd rx to listen to the offending signal and the software produce an anti-phase 'key click' in the main receiving bandwidth to cancel the clicks...?

Re: [Elecraft] K3 Error Message ERR AT3
Hi Dave, I too get this intermittently on my K3 #145. Probably been more frequent of late and also disables the ATU though oddly it still responds to checking/adjusting the LC settings from the menu ok - you can hear the relays clicking but press the ATU button or ANT1/2 and no response... However up till very recently I wouldn't get just ERR AT3; instead I would get a whole series of random error messages which would include AT3...eg BP1,IO3,AT3,BP3,IF2. When I cancelled each in turn by pressing buttons to get back to 'normality' the only thing that seemed to be not working was the ATU and if I recall correctly occasionally the Noise Blanker too; otherwise all worked fine. Last couple of times though just the one error (AT3) has appeared like you report. Checked the AT3 seating and OK; also never had any problems with turning off so maybe that's just coincidence with you. I did check with support a while ago and suggested checking the KAT3 board seating - not a show stopper but certainly is weird. 73, Stewart Rolfe, GW0ETF David Y. wrote: Hi All, Early on my K3 (#96) had an issue where it would not turn off without removing all power connections.

Re: [Elecraft] [K3] K3 - Intermittent Loss of RF Output
Jeff, Unstable rf power output has often been discussed here. It was a problem in the early days (I have #145) but in my own experience has now largely disappeared. However very occasionally it inexplicably reappears out of the blue and I'll get a session of unstable output which like stocks and shares can go up as well as down. This morning I noticed the display on my Acom 1000 wobbling a bit which is a sign; just once it suddenly shot up to f/s and then settled back down to more or less normal. This is the first occurence for literally months. After so much time I'm convinced it's not hardware/loads or rf getting into the control circuitry...it's as if the software control has a migraine or something. It's never actually been so bad to actually stop me, even early on, so if your instability is as bad as that on a new build it maybe a physical/hardware issue. I'm sure the Support crew will help you out there. Good luck 73. Stewart Rolfe, GW0ETF J.A. Wolf, MD, K6JW wrote: I recently completed a K3 kit.

Re: [Elecraft] K3 VFO tuning hash
Wayne et al, I too can confirm the existence of what intuitively sounds like encoder clicks on the bottom end of 10m as well as the lower ends of 15 and 6m. Most times they are masked by antenna noise (and some pc low level hash here on 6...!) but it does seem to vary in 'severity' so I was interested in your comments about I/O devices etc. The bottom end of 10 does seem consistently the worst though. A couple of observations from here:- 1/ When switched on both RIT and SUB encoders produce clicks. 2/ The Main encoder produces clicks also in the SUB rx and vice versa. 3/ SHIFT/LO and HI/WIDTH controls also produce clicks. DSP helps and ofcourse it doesn't ultimately interfere with a qso. I've only noticed this since using 10m and then not all the time and I've yet to double check the mechanics/wiring inside the radio. 73, Stewart Rolfe, GW0ETF K3 #145 (V3.19 and pretty well modded up to date) wayne burdick wrote: John, I've noted your report of VFO tuning noise on 10 m, and will look into it further when I get back from vacation.

This is probably an N1MM issue but thought someone on here may have something useful to say I finally got round to properly setting up the dual transceive SO2V on my K3 for N1MM and it seems to work a treat. I can now have the 2 entry windows open with VFO A running and B set for SP on the sub receiver frequency; CTRL Left/Rt Arrows flick between A and B (invoking SPLIT for B to tx on the sub qrg) and while running I can hit \ to put an SP call in the VFO B box to check for a dupe etc. Just one minor annoyance/oddity; I use ESM all the time (mainly cw here) and have a footswitch on an LPT port set for ESM ENTER. But it appears the footswitch only acts on VFO A which is normally set up for running. So if I've swapped to VFO B to SP someone and then hit the footswitch to send my call (F4) the focus swaps back to A and I end up calling CQ on my run frequency instead. No problems if I use the keyboard ENTER key. I've tried changing the LPT Radio number from 1,2 to Both etc but no difference. Any ideas folks? I'm assuming it's an N1MM issue so it's also gone onto the N1MM Yahoo board. 73, Stewart Rolfe, GW0ETF -- View this message in context: http://n2.nabble.com/K3---N1MM%2C-footswitch-and-ESM-action-tp3132037p3132037.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] CQ Contest
Dave, I too operated SOSB20 as GW6W last weekend and concur with your observations including being slightly uneasy at times at being able to slot in so close to neighbouring signals - didn't suffer any 'band rage' though so presumably they would be using something decent too. We were in the middle of a heat wave and the ambient temperature in my small shack with the Acom 1000 running continuously was in the 80s (F) most of the day hours but FP and PA temps were fine and I stopped checking them after a short time. Contesting with the K3 filtering is a joy; but last March I took the K3 to the Gambia and had some big pile-ups from C56ETF. It was my first dxpedition experience and I imagined I would be using the narrowest filtering to tune progressively through the split pile-up; what I actually found much better/easier was to use a relatively wide filter setting and pick out the signals from the 3D space between my ears with the AFX. Did wonder what the throng thought of my erratic jumping around compared to the probably more normal progression from high to low or vice versa. Region 1 Field Day is this weekend and K3s will be in action from GW4TTA/P. There's a pic from last year's SSB field day featuring some Elecraft gear - www.radioclubs.net/dragonarc/articles.php?articles_id=341 - and no it isn't SO3R. 73, Stewart Rolfe, GW0ETF (K3 #145) David Gilbert wrote: I operated SOSB20 in CQ WPX this past weekend and gave the K3 a pretty good workout. I made 1300+ contacts but that pales in comparison to the zillions of times I repetitively hit the F1 key. My wife and I have been building our own home the past few years and we still don't have the air conditioning functional, so the ambient temperature in the shack was right at 80 deg F much of the day. I set the K3 to continuously monitor PA temp, and even with the relatively large duty cycle I was giving the rig I never saw it go above 47 deg C. The other very impressive thing was the narrow filter. I used a 250 Hz 8-pole filter with the DSP set to 250 Hz, and it was like a knife edge. I could operate within a couple hundred Hz of most S9+20 stations and never hear them --- unmodified Yaesu rigs being the exception (there are still some HORRIBLE sounding clicks out there). Whether those stations heard me was probably a function of whether they were using a K3 or not ;) The downside was that I had to ride the RIT most of the time ... I had a LOT of people call me pretty far off frequency and the only way I could tell they were there was by the rhythm of their key clicks unless I swept back and forth with the RIT. Which brings up a side observation ... there is so much disparity now between the performance of various rigs that it seems possible to generate some misconceptions regarding operating skill and courtesy. I wonder how many times other stations thought I was deaf or couldn't copy their CW merely because they couldn't zero beat my signal within 150 Hz or so? And I wonder how many people thought I was a LID for calling CQ too close to them on what was for me a clear frequency because they didn't have as tight a filtering as I did? To minimize the latter, I usually opened up the bandpass a bit when looking for a clear frequency, but the folks with 500 Hz filters and no roofing filters would have still had trouble. 73, Dave AB7E -- View this message in context: http://n2.nabble.com/CQ-Contest-tp3013326p3016811.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] NB/NR Noise Blanker/ Noise reduction
If I look at the audio response in Spectrogram while feeding in a noise source at the antenna the trace shows definite nulls when NR is switched in. In SSB at max width (2.7kHz) the number of nulls vary with the settings as follows: F1-# 9 F2-# 7 F3-# 4 F4-# 3 As # is increased from 1 to 4 at each F setting the depth of the nulls decreases and it's almost flat at #4. However RF gain and AGC slope settings drastically affect the depth of these nulls but at maximum the nulls are about -30db which would presumably affect the 'loudness' of a signal if it happened to fall in one of the holes? I don't have time at the moment to investigate further how the AGC settings affect the nulls but backing off the RF gain definitely flattens the response. According to Lyle back in 2007 the F parameter indicated the number of taps (?) in the adaptive filter and the second number the amount of signal 'bleed through' to reduce distortion effects. I'm not sure my limited knowledge of dsp and filters ties this in with what I see in Spectrogram. Having said this I must admit I tend to use filtering in preference to NR even though I seem to be able to get NR to work pretty well. 73, Stewart Rolfe, GW0ETF Steve Ellington wrote: This is amazingWe have some who complain about NR increasing the audio and some complaining about it reducing audio! -- View this message in context: http://n2.nabble.com/NB-NR-Noise-Blanker--Noise-reduction-tp2728863p2732318.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] K3 temperature
Since K3 #145 has had it's sub receiver the forward area of the right hand side panel seems to get a little warmer and I've assumed this is due to the sub rx or second dsp drawing extra through the 2 voltage regs bolted to that panel. Shows it's all working ok since the panel is the heatsink for those devices. I don't understand how you could suspect the sub rx of increasing the PA temperature if everything has been installed correctly. BTW: I took part in a local RTTY contest for the first time the other evening and was a little concerned about running full power despite reassurances here. Running about 95 watts for 90 contest minutes I kept an eye on the PA temperature and it never went above 46 deg; I put my hand over the back once or twice and the fans seemed to be running but only slowly.

[Elecraft] K3 - CW Sidetone in Dual Receive
Christened my freshly installed KRX3 at GW0GEI (M2) for the weekend cqww. It arrived just in time (ordered February 1...) and was fitted without incident the previous weekend; the K3 and (qsk) Acom 1000 worked flawlessly for the whole 48 hours. I found the whole 2 receiver thing an interesting and new experience. Being able to hold a run frequency with pc sent CQs while scouring the band for mults/unworked with the second rx was really useful particularly late on the Sunday when runs got slower. Not really sure if I was using the best method but it would involve tracking a potential contact on the KRX3/right ear, a quick Alt-F10 (N1MM) to swap sub to main (right to left ear..), work 'em and Alt-F10 again to resume. So here's a question/comment.to me it would make sense if you could have the cw sidetone only in the left earpiece when operating dual receive. Bearing in mind my position on the learning curve and lack of sleep, I was sometimes losing track of which signals on either side of my head I was transmitting to which lead to the occasional muddle - multitasking has never been my strong point but I definitely felt keeping the sidetone associated with the transmit frequency would have been handy. Apparently the key term is SMOC - so if it *is* just a small matter of coding I wonder what others more versed in the black art of dual receive think? 73, Stewar Rolfe, GW0ETF (K3 145) PS - Nice to work you Hank (K8DD) on 20m; over here 20 and higher were very poor, 80 was terrific but 40m was the place to be. -- View this message in context: http://n2.nabble.com/K3---CW-Sidetone-in-Dual-Receive-tp1598236p1598236.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 keying
Barry, Shortening of characters in QSK is a common issue in many transceivers though it seems less of a problem in the K3. What you should really use to combat it is 'Keying Compensation' which you will see in for example Winkey configuration settings and other external keyers; it lengthens each character by a fixed amount (x millisecs) and is independent of keying speed and is designed specifically for this problem. Think I'm right in saying the K3 internal keyer doesn't have this adjustment (yet?). When I checked my K3 on my 'scope the shortening in qsk looked pretty minimal but I find a setting of 3ms makes the (Winkey) keying feel 'sweeter' so that's what I use... 73 and look out for you this weekend at GW0GEI (M2) Stewart Rolfe, GW0ETF Barry Simpson wrote: No one has commented on the apparent shortening of the first dit as illustrated in the QST review, Figure 1. My K3 keying does not have that issue as far as I can judge from listening on a separate receiver. What is does have is a disparity between keying weighting between MOX (either front panel switch or foot switch) and VOX/QSK. Compared with MOX which has characters about the same length as my other rigs on my keyer's 50% weighting setting (ie it is about right) the characters in VOX and QSK are shortened. I simply overcome it by altering my weighting to 58% and not using MOX. I note that Elecraft deal with the same issue by having the weighting set at 1.15 in the config menu. Not a real problem - just an observation. Looking forward to giving the K3 a good workout this weekend.

Re: [Elecraft] K3 NR (was making K3 RX audio like K2)
Not sure what mode is being referred to here, but I will assume CW as this is the mode most suited to NR. I find RX EQ settings have a significant effect on NR; I have boosted the 400-800Hz channels a few dB and that causes the cw note to appear to 'jump out at you' under NR along with reduction in the noise. Can't remember NR settings but it's not extreme and I aim for least echoing and character softening... I also had an FT990 before the K3. It was a great radio but I don't find myself hankering after it's hifi audio while listening to my K3; I'm sure the overall audio quality was no worse than the K3 but as with the K3 I only ever used the internal speaker - one less potential rfi path for one thing.

Vic, You probably won't be using NR at these narrow bandwidths anyway; it's been explained before by Lyle and quoted in the message in this thread from Bill W4ZV: NR is rarely useful if the bandwidth is narrow. If you set your CW width to 400 Hz or less, for example, there is no point in running NR *unless* you want to use it as a sort-of smart squelch.

Re: [Elecraft] K3 NR (was making K3 RX audio like K2)
OK I've just checked this out and Vic is entirely correct.boosting the cw tone frequencies certainly does cause a drop in signal when the dsp bandwidth crosses from 150 to 100Hz, NR or no NR. (and conversely cutting those frequencies leads to a sudden increase in signal at the crossing point - it's quite dramatic) Glad I found this out before cqww but a little bemused as to why this 'feature' hasn't been better circulated; I've been using my K3 for a year now and have never seen mention of this. Thanks for the heads up Vic (I think that's the term...!)

Wondering now if I should instead go for another 500Hz 5 pole roofing filter for the KXR3 and have it matched to the original? Would this make sense should I want to use diversity rx (apologies - haven't really studied this...)? The email says they can supply a matched unit for an extra $30 so the cost would be the same.

[Elecraft] K3 - 'Unwanted' TX Gain calibrations?
Been wondering just how the TX Gain calibration works. To quote from the manual - The gain constant is updated whenever the TUNE function is activated on a given band at one of three specific power levels: 5.0W, 50W, and 1.00 milliwatt. So if I'm adjusting my external ATU by TUNE(ing) at say 5watts, will the (LP)Tx gain constant be updated while feeding into an unspecified load. The described procedure requires the use of a dummy load to set the gain constant; if the load isn't 50 ohm resistive will the constant be set to some anomalous figure which may not be updated when the atu eventually presents (hopefully) 50R to the K3??

Most good external keyers offer 'keying compensation' in msecs to offset this; my FT990 needed as much as 8ms extra on the characters to give a 1:1 dit ratio in qsk v semi break-in.

Re: [Elecraft] K3 erratic power output
k7ca wrote: Hello All, I just received K3 kit serial # 1253 with KPA3, KBPF3, KXV3 and KUSB options. The kit was very well thought out and was a pleasure to assemble. It went together in under 8 hours. Everything seemed to calibrate well and work perfectly except for the 100 watt PA. When running 12 watts or less (8 watts on 6m) output is good and stable. When power is set higher which causes the 100 W PA to turn on, output power is not stable. On 20m thru 6m with key down the power output takes about 6 or 7 seconds to stablize. For example, when the power control is set for 50 watts it first comes up to 35 watts, then slowly goes up to 60 or 70 watts, then slowly comes down to 50 watts where is is stable. It seems like the power control zero's in on the correct power but very slowly. With CW it never gets there. This happens every time the key is opened and then closed again. On 40m the same thing happens but there is about a 3 second delay after key closure before any output is seen. There is no power output at all on 80m and 160m even though with less than 12 watts set on the power control there is normal power output. I haven't had the time to look into the schematic yet so thought I'd see if any of the list readers have had a similar experience or may have some idea of a good place to start.Thanks, Al K7CA Al, There have been posts previously about erratic power output but maybe not describing such an extreme situation as yours - no output (high) at all on some bands suggests something more serious than erratic power control:-( I have occasionally found the power output to suddenly start changing (CW) but it has happened only rarely and never sure if it is connected to a software upgrade or not. Mostly it manifests in the power indication dropping from the '100 watt' level to anything from 35 watts to 80 but it always seems to recover quickly; it is a genuine power variation as checked against an external power meter. Once when I was using my amp it went the other way and increased up towards full power which meant I was briefly knocking out about 1200 watts - I wondered whether Elecraft would bail me out if a man in a grey suit came knocking complaining about me operating outside my licence conditions...:-) It happened again fairly recently and I went back to the last full firmware version (2.02 I think) and I've not noticed it since. I'm not convinced though that it is linked to software but I've not even thought about hardware yet 'cos I'm waiting for a KRX3 which will involve some dismantling and checking of connections etc. Can't be a widespread problem though in view of the dearth of posts on this but it does seem to exist and hopefully if it is a 'real' problem compared to dodgy contacts somewhere, it will be resolved soon. I do wonder if the lack of reporting is because of the fact that it will be much more obvious in CW and may well go unnoticed in ssb.

[K3] [Elecraft] [k3] Wattmeter calibration
Finally I got round to checking the wattmeter calibration as I've felt it's been giving out power levels below what the wattmeter on the front panel reports ever since I've had it. First alerted when my Acom 1000 seemed to giving low output until I saw the amp's input reporting a significantly lower driving power eg 35w as against a K3 setting of 45w into a dummy load. Also 2 independant power meters seemed to agree even though admittedly they weren't lab standard. So I did the configuration while measuring voltage across a dummy load with my 40MHz 'scope and found I needed to wind the WMTR HP setting way down to minimum (010) to get the power up to 50 watts on the 'scope (and yes I did remember the RMS to peak conversion ;-). Seeing that the default setting is 100 I thought I might ask others what setting seems to be the norm. Needless to say I've not noticed anything odd about running 80 or 85 watts instead of 100 these past few months but (wrong) numbers do have a habit of bugging you eventually 73, Stewart Rolfe, GW0ETF (K3 145) -- View this message in context: http://www.nabble.com/-k3--Wattmeter-calibration-tp18155295p18155295.html Sent from the [K3] mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 noise reduction
I'd recommend a read of Lyle's description of NR in the FAQ and also in 'Operating Tips'. From this it's clear this sort of adaptive filtering is going to be most effective for CW. I've been using it with F2-3 setting and it works fine for me (on CW). On signals other than very weak ones (which Lyle points out could be adversely affected by NR), the audio actually appears to increase a notch if anything. There is a small amount of distortion on the audio with the most noticeable being a softening of the cw characters which will make copying slightly more problematic in difficult conditions. Having said all that I still use filtering first and foremost before falling back on things like NR; and to comment on the suggestion that NR should remain on after switch off, I remember ages ago Eric or Wayne saying they specifically designed the NR *not* to remain on as folk were contacting them complaining their receiver had died when they switched their K3 back on and not hearing any background hiss - the NR is that good!

Re: [Elecraft] RSGB RadCom K3 review posted on RSGB Members web page
I don't understand why the IMD figures worsen as the roofing filter narrows. Also I've always been led to understand that the signal spacing likely to cause IMD problems is roughly 0.25 of the roofing filter bandwidth assuming a narrow final passband. On this basis, and even allowing for responses down to the -60dB level (say 5kHz for the 2.7K filter...) none of the quoted signal spacings should be 'getting through' any of the roofing filters listed. So at these spacings the IMD response should be a function only of the pre first mixer circuitry which doesn't explain (to me!) the significant variations with roofing filter. I'm sure I'm missing something here, perhaps about how these things are actually measured; anyone care to put me right?

Can't yet find a way of referring back to a particular message so have copied the text below also.. Have fun, Stewart Rolfe, GW0ETF (K3 145) Start of quotes http://www.zerobeat.net/mediawiki/index.php/K3_DSP by Lyle KK7P Dec 22, 2007; 03:31pm :: The NR has changed with time and may continue to do so. As a result, the manual is general in its treatment. The overall rule is more is more. NR is more properly Signal Enhancement rather than Noise Reduction. The distinction is subtle but important if you wish to understand how it works and how to best apply it. If ti were noise reduction, the implication is that it passes everything until it figures out what is more likely to be noise, which it then attempts to suppress. Since it is signal enhancement, it tends to pass nothing until it figures out that which is more likely signal, which it then attempts to pass. With this understanding there is one more concept I must explain: correlation. This is the degree to which a signal is similar to itself; conversely, it can be used to figure out how noise is dis-similar to itself (more random). This is the basis on which NR works. In the current implementation of the K3, we have four (4) basic NR filters. These are displayed as F1..F4. F1 is the gentlest, F4 the most aggressive. Recalling that the filters tend to suppress everything until they can sort out what is probably a signal, there is some time delay involved in their application. Further, especially with voice signals, some components of the signal may not be recognized as well as others. THis gives rise to distortion. So, we added a second field to the NR. This is the -1..-4 which specifies a certain amount of bleed through of the original signal. This reduces the apparent distortion and delay, but limits the ultimate S/N improvement. -1 provides the least distortion but limits the S/N improvement on weak to moderate signals to about 6 dB. -4 provides no mixing whatsoever and can result in dramatic S/N improvements, but at a cost of slight time delays and increased distortion. NR is not appropriate for very weak signals, so a -1 or -2 is best if you wish to hear them. Having saids al this, the correct way to use the NR is to listen and adjust it for the best compromise between noise reduction and distortion. Everyone is different in this regard. Some tolerate noise better than others, while some don't tolerate distortion very well at all. I live in a quiet location, and use NR1-2 as my most common setting. This is low in distortion, allows me to hear weak signals, and shows no apparent delay as I tune through the bands. On the rare occasions when things get noisy here, I crank it to higher values. Probably a much longer answer than you wished.
