[Elecraft] Does K2 benefit from simple Microham interfaces?
Is there any advantage in using a simple microham interface like USB2 or CW keyer for K3? It seems that the serial cable can provide both radio control + CW keying+PTT. The data connection is straight. There are provisions for separate paddle. Not sure how RTTY would be handled without an interface. I understand advantages of interfaces in more complex situations like SO2R or when a single USB connection with the computer is desirable.

[Elecraft] Reminder - UK Elecraft net Sundays 1000 local, 3630 KHz NOTE NEW START TIME
Following a request for a move of frequency to 3720 in order to clear European QRM, I asked what others thought with various options. There have been some 49 stations call into the UK net at various times - probably not all read the Reflector, but I would have thought more than 4 would reply! One station pointed out that he couldn't operate on 3720 as his antenna was tuned for lower in the band. Three favoured starting an hour later. We will therefore try an hour later on the same frequency, 3630 +/- QRM, starting at 1000 local (currently 1000 local UK time = 1000 UTC). 73 and see you in the morning.

[Elecraft] K3-Hardware agc mod and S-meter cal
Have an early K3 here and have just done the hardware agc mod, spurred on by cqww ssb a fortnight ago :-) Mod went super smooth but am wondering about the recommendation to recalibrate the s-meter; is it just a precaution or is the s-meter guaranteed to be out after the mod?

[Elecraft] KSB2
Curt, I have 2 K2s and both have the KSB2 option. First, Installing the SSB option and aligning it correctly doesn't reduce the K2's effectiveness in the CW mode, in fact it inhances it. Second, This option opens the door to digital, SSB and sstv communications. If your K2 is stock CW then you have to remove the front panel to install the mic circuit components which is a pain but easily done. You will be glad you install this option (even if you don't use SSB). 73 Dave KD1NACompleted K2 s/n 6424 a few months back, am thinking of adding a KSB2 adapter kit I own. I've seen several threads indicating that the SSB performance of the K2 with the adapter isn't very good. Would adding this capability be worthwhile, or is leaving the K2 as CW only a better option? 73, Curt KB5JO ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 N1MM and the second Band Map
Hi Berni, Did you tick the SO1R box in the Config menu ? N1MM explicitly states to do that instead of SO2V, because (for reasons I do not quite understand) the K2/3 do not support the SO2V feature.

RE: [Elecraft] Does K2 benefit from simple Microham interfaces?
My experience is that keying the radio via RS-232 control lines is sometimes problematic with some logging programs using a multi-tasking operating systems (like Windows NT and its derivatives), and that problem doesn't always show up until the log is large and you're late into the contest. I find a WinKey to be very convenient. The K3 does allow a computer program to send CW using K3 commands sent over the K3's serial port (see the KY command in the K3 Programmer's reference). However none of the popular contest logging programs support this method of sending CW. I'd ask Joe Subich, W4TV, who would know the answer to your question.

RE: [Elecraft] Firmware updates
That's not my experience. Just yesterday I unzipped a the current beta version into a folder named K3FW2R63 that was a subfolder of My Documents. I used the K3 Utility Firmware page Browse button to navigate to that folder and I loaded the K3 directly from that folder. To download non-beta firmware into a folder of your choice, first create a folder (perhaps using the Windows Explorer). Then navigate to that folder with the K3 Utility's Firmware Page browse function or type in the location of the folder. Check the copy files from Elecraft check box and click Check Versions Now. The K3 Utility should copy all the files into that folder, whether it's the default folder or not. The K3 Utility doesn't create a folder for you.

RE: [Elecraft] K3 vs. HPSDR Mercury receiver
Next generation transceivers will not use crystal filters and mixers, they are already appearing and the performance is outstanding. If the next generation of transceivers does in fact abandon narrow filtering ahead of the ADC it will be a sorry step backward. While some of the designs like the Flex-5000 and Peresus have excellent specs for the most part when tested against two tone situations, they are still substandard in dealing with multiple very strong in-band signals as would occur on 160/80/75 meters in a contest or on 40 meters with the multiple megapower broadcasters. To maintain linearity, an ADC must be able to withstand the instantaneous peak signal (vector sum - not average) from all the signals within its passband. For some DSR designs that maintain bandwidths from several hundred KHz to 10s of MHz that peak signal handling capability requirement can be significant and represents a required dynamic range orders of magnitude greater than even the best current technology. It is the multi-tone interference that is best handled by narrow filtering ahead of the ADC (e.g., the K3 design). 73, ...

That will remain the weak link until ADCs with higher resolution that the current 24 bits is exceeded. BDR is important in multi-transmitter environments or if you are close to a neighbor (amateur or commercial BC station) that has very high signal levels (which trigger ADC front-end protection and thus limit BDR). Until the BDR of current generation SDRs is improved, we will not see pure SDR rigs (without crystal filter front ends) be competitive in contest environments. 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/K3-vs.-HPSDR-Mercury-receiver-tp1471026p1473801.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.

[Elecraft] K2: Various Receive Problems
I just finished building the K2 and am in process of checking it out. All voltage tests, current tests, power tests, alignment tests and alignment activities were completed successfully. I've been through the receiver alignment twice just to make sure, and got good peaking on each band. I'm hitting various receive problems that are just strange and I'm going to have a little trouble explaining some of them, so please bear with me. 1. Receive sensitivity is not good. Using the same antenna, and with AGC on: o Without the pre-amp on, the K-2 is nowhere near as sensitive as my K-1, nor is it as good as my FT-897 (but the K-1 is better than the FT-897). o With the pre-amp on, the K-2 is about as good as the FT-897, but still not as good as the K-1. The situation is better with AGC off, as good as or better than the FT-897, but still not as good as the K-1. It seems as if the AGC is having too much impact since I have to crank the AF Gain almost all the way clockwise to get decent audio volume with the AGC on (both headphones and speaker)? 2. On receive, stations are either there or not there. In a correctly operating radio, as you tune across a station's signal, the signal strength starts out lower and then picks up in strength and volume as you reach the station's actual transmit frequency. Furthermore, if two stations are near each other, you typically hear both of them. In this case, if I hear a signal, I hear it at the same volume as I tune across the signal's bandwidth. The perceived signal strength simply does not change. The S-Meter does change value, but not the perceived signal strength in the headphones or speaker. Along with this, there is no interference from adjacent signals. I'm always hearing the strongest station and only the strongest station at whatever spot that my VFO is tuned to. Any other stations are simply not there, as if some sort of really good DSP has completely eliminated all but the strongest station at that point in the VFO (and I mean *completely* eliminated). As you tune across, you can hear the specific point where one station stops being heard and a different one starts being heard. I do not have DSP -- this is a bare bones K-2 without noise blanker or anything else. I have AGC turned off. The problem also appears with AGC on. In addition, it appears in both VFO A and VFO B. I have the squelch turned off. I have checked, and I'm in filter 1 and I'm getting the correct readings from aligning FIL1. When I go to FIL2, there's a similar effect -- except that the bandwidth range across which I can hear the signal is much smaller (to be expected with a tighter filter). At FIL3 I can hear only the strongest of stations, and then across an extremely narrow signal bandwidth. Finally, at FIL4 I cannot pick up even the strongest signals. 3. As I tune across a CW station's signal, there is no change in audio frequency. In a correctly operating radio, as you tune across a CW signal, there is a change in the audio frequency of the signal, until you're at zero-beat, at which time the audio frequency is whatever you've set your sidetone at. In this case, once I hear a signal, I hear it at the same audio frequency across the entire bandwidth of the signal for as long as I'm hearing that signal (see problem 2 above). The audio frequency at which I'm hearing the signal is not particularly my sidetone frequency. It seems to be different for each different station, but is the same for the same station. For example, I'm hearing a station at 14.100. As I tune across his signal, the audio on his signal is at about 800 Hz. As I tune past that (up), I hear another station and I'm hearing the audio at something much lower, like about 500 or 600 Hz. If I keep tuning across the dial, I'll hear other stations, each of which may or may not have a different audio frequency than 800Hz. However, if I go back to the station at 14.100, I'll again hear him at about 800 Hz and not some other frequency. I can hear this particular station from about 14.099 to about 14.101, and his audio frequency does not change as I tune the 2KHz range between .099 and .101 I get the same result with SSB signals. There is no change in the audio, and thus most SSB signals are unintelligible because there is no way to tune in on the station's actual transmission frequency. Every so often, an SSB station is intelligible, and then no amount of tuning across its bandwidth makes it unintelligible. Note that I do not have the SSB module installed, and I'm not sure if I'm supposed to be able to hear SSB in a bare-bones K-2 without the SSB module installed (although it is my understanding that I should be copy SSB). * I've been through the manual twice and can't find any features that I may have inadvertently turned on to get these results. Any suggestions would be appreciated. Thanks in advance.
[Elecraft] Some Basic K2 Opinions and Information
Hello everyone, I'm considering the purchase of a K2 and would appreciate any information and/or opinions that you might have. I'm strictly a QRP guy so I'm not interested in the 100-watt version. I would probably want the internal tuner. I don't work SSB, but PSK is of some interest to me so I'm thinking about the KSB2 option. Other than that, since money is definitely an important consideration, I would be very interested in opinions about the KIO2 RS232 interface - would it help with PSK? I would also like opinions on the KAF2 filter vs. the KDSP2 DSP filter. My current rig is a K1 so just about anything would be gravy to me - I'm not comparing the K2 to some Rolls Royce kind of rig. Thanks in advance for any help that you can offer. 73, Paul - N8XMS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] Some Basic K2 Opinions and Information
HI Paul, I enjoy my K2, with about all that you are looking at, the noise blanker does its job very nicely on ignition noise, and an electric fence, that my horses insist on messing with. The rs232 interface hasn't been used here yet. The DSP filter is a good addition, especially in the crowded conditions of cw at times... especially for continueing the chat, when someone moves in a bit too close, because they don't hear as well. And the hearing as well is an outstanding feature. I find myself cuddled up to a QRO station, and not even know he is that close, until the other station says something.. then I open the rx up a bit, and there he is.. especially when I do a side by side with other rx, it becomes very very obvious, the filter skirts are better and the shape of the bandpass is better than other rx, until you get way up into the drool region and that would be right up there with the K3. The one other thing that is a key point... very key.. is that Wayne and Eric, and the rest of the Elecraft crew, are very responsive to requests, and the expanse of excellant information, very helpful with all the assistance that is so missing from other brands... is right here. Jump in, enjoy, and get the best. --... ...-- Dale - WC7S in Wy _ Windows Live Hotmail now works up to 70% faster. http://windowslive.com/Explore/Hotmail?ocid=TXT_TAGLM_WL_hotmail_acq_faster_112008___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Switch tone glitch
I notice a small glitch with the SPOT switch now that switch tones are enabled. The switch is a little finicky in that if you tap it very briefly the spot tone does not activate. You have to dwell on the switch just a little longer than a quick tap in order to activate SPOT. Actually, there is not much point to having a switch tone for SPOT/PITCH at all. 73, Drew AF2Z ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 vs. HPSDR Mercury receiver
The explanation from the article is as follows: When noise pulses/spikes pass through a crystal filter, the phase response of the filter changes, depending on the noise frequency. However, when noise pulses/spikes pass through an ADC with a linear response, the phase response stays the same, because the ADC treats them in a linear manner. While the K3 is SDR, it also includes crystal roofing filters which the Mercury does not. My Perseus SDR (which also operates with a high speed ADC for direct decoding - no crystals or mixers) does deal with noisy signals better than my K3. Next generation transceivers will not use crystal filters and mixers, they are already appearing and the performance is outstanding. 73 Dave, G4AON K3/100 #80 - / SDR where the authors compare a K3 with a HPSDR Mercury receiver and // explain why the SDR sounds better than the K3 (noise through a crystal // filter causing phase changes). / The K3 is also an SDR! -- David Woolley ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] CW to PSK encoding
Have any of you noticed that when using a cw paddle to send PSK from the K3 a few of the translations are not correct. For example, when sending 1234567890 from the paddle, the K3 transmits 123 E g w C O9 0. If I put a space between all the numbers, then I get a correct translation. That wouldn't be too bad, except that when ever I send my call k7ca, the K3 sends k Cca. Again, if I leave a spact between the 7 and c then it comes out ok as k7 ca.

RE: [Elecraft] K3 vs. HPSDR Mercury receiver
For casual SSB operating I listen to my LP-PAN / PowerSDR panadapter which is fed from ahead of the xtal filters, and for dabbling in contests or operating CW (where latency can be an issue) I listen to the K3. I am not in Europe where things can be dicey, but I have yet to see enough total peak energy in the passband to affect the ADC of the panadapter. 73, Larry N8LP Next generation transceivers will not use crystal filters and mixers, they are already appearing and the performance is outstanding. If the next generation of transceivers does in fact abandon narrow filtering ahead of the ADC it will be a sorry step backward. While some of the designs like the Flex-5000 and Peresus have excellent specs for the most part when tested against two tone situations, they are still substandard in dealing with multiple very strong in-band signals as would occur on 160/80/75 meters in a contest or on 40 meters with the multiple megapower broadcasters. To maintain linearity, an ADC must be able to withstand the instantaneous peak signal (vector sum - not average) from all the signals within its passband. For some DSR designs that maintain bandwidths from several hundred KHz to 10s of MHz that peak signal handling capability requirement can be significant and represents a required dynamic range orders of magnitude greater than even the best current technology. It is the multi-tone interference that is best handled by narrow filtering ahead of the ADC (e.g., the K3 design). 73, ...

Re: [Elecraft] CW to PSK encoding
What firmware version are you using? The release notes for version 2.57 include: PSK31 (PSK D MODE) TRANSMIT IMPROVEMENTS: Eliminated erroneous characters during CW-to-PSK31 transmit when using the keyer paddle. Also greatly improved PSK31 transmit speed by removing all extraneous zeros from the data stream. I hadn't noticed any erroneous characters myself, just errors of my own making since the decoder is strict about the timing of morse elements. The feature has been quite useful for casual contacts when I don't have the laptop at home or don't want to bother bringing it into the shack and setting it up for psk31.

RE: [Elecraft] Some Basic K2 Opinions and Information
I built my K2 several years ago (#1609) and have been very pleased with it. I do digital modes, PSK RTTY, almost exclusively and I would recommend the following 1. KIO2 - Highly recommended - this provides computer control of the K2 and integrates your K2 with the software. Wouldn't leave home without it. 2. KAT2 - Highly recommended if you are not going to have a tuned antenna. I use random wires because of antenna restrictions and have good luck getting a match. 3. KAF2 - I have the KAF2 and do not use it much. I'd really like to see the center freq around 1000 Hz for digital modes which can be done with some component changes. This mod is still on the to do list so that gives you an indication of how much I use it. I'd wait and add this later (it's easy to do). Helps with the cash flow, as well. 4. KDSP2 - Don't have one so I can't offer any help. 5. KNB2 - The noise blanker is of marginal use in my rf environment Others have found it very useful because they had specific kinds of pulse noise to deal with. If you get one you need to keep the RF gain up so that there is enough signal to trigger the blanking. Remember, most of these modules can be added after you build the K2. When I built mine, I checked the manuals for the modules to see what modifications were necessary to install them. Any parts that needed to be removed, later, I installed with extra lead length so they would be easier to take out, when the time came. When I built my K2, I got a PWB holder and found it very handy. There are a lot of parts to stuff and solder. Not having to juggle the PWB at the same time made it that much easier. Good luck and enjoy the building.

RE: [Elecraft] Does K2 benefit from simple Microham interfaces?
Probably. Any of a number of unexpected task switches cause CW keying to be interrupted. The ones I can think of are: 1) Virus checker phoning home for a file update. 2) Virus checker starts a file scan. 3) Adobe decides it needs to phone home to check for updates. 4) Apple QuickTime decides it needs to phone home to check for updates. 5) Microsoft Windows Update decides it needs to phone home to check for updates. 6) Sun Java virtual machine decides it needs to phone home to check for updates. 7) Real Player decides it needs to phone home to check for updates. 8) Spyware scan starts. 9) Content indexing starts or 10) Contest log gets large and check partial or rescoring takes more time. These are mostly activities that can be turned off if you know how to do it and are vigilant. After the contest you probably want to turn them back on again.

RE: [Elecraft] Does K2 benefit from simple Microham interfaces?
I'm not exactly sure of the timing requirements, but sending well-formed CW at 30+ words per minute requires timer resolutions in the low numbers of millisecond range. This can be done with high resolution timers (introduced for multi-media), but you need to have the process priority right so that the program that is turning the serial port (or parallel port) control lines on and off can get control within a very few milliseconds of the desired time. Often higher priority things like disk I/O interrupt handlers and programs that are I/O intensive can keep control away from the (user priority) program doing CW long enough to cause grief. Disk I/O from paging in programs is often a higher priority task than any user-mode program. I've seen some low-level device driver level solutions (I recall N6TV wrote one for OS/2) that can get close, but this isn't the way that the popular logging programs do it. I'd recommend a WinKey. Standalone it costs a few tens of dollars (the basic K1EL Winkeyer2 serial is only $36), and if you're into contesting at all you'll find that it eliminates a problem that can cause great consternation at really unfortunate times. I use microHAM products that incorporate WinKey chips. They work quite well for me.

Re: [Elecraft] Q re Missing K3 Kit part
It's not a show stopper. It just helps you provide a little extra pressure as you push the FP to the RF board. It's nylon, it doesn't make a connection so there's no apparent impact to the circuit. I didn't have the stand off either in my kit SN 2105. I managed to use my finger to push the DSP board (tight squeeze) as I sandwiched the FP+DSP onto the RF board. You have to be careful not to flex the boards. It'll go. The connectors on the RF board to the FP will mate easier than you think. Be careful, but it's not a show stopper. Of course, Elecraft may have a different answer... -jeff On Sat, 8 Nov 2008, Grant Youngman wrote: I'm missing one lousy part -- a 5/8 nylon standoff that gets mounted on the DSP board (assembly errata E-7, item 3) to provide some spacing from the front panel board.

On Sat, 8 Nov 2008 05:52:28 -0800 (PST), Ignacy wrote: Is there any advantage in using a simple microham interface like USB2 or CW keyer for K3? For five years of serious contesting, I've never used anything more complicated than a serial cable and breakout of DTR through an NPN to the key jack to send CW. I've used this with WriteLog and N1MM with a K2, K3, TS850, Omni V, FT1000MP, and IC746 with no problems in a SINGLE RADIO setup. The computers I use have REAL serial ports, not USB-derived ports. One has no built-in serial port, so I use ports from a Quantech PCMCIA card, which act like real serial ports. The K3 has the advantage of not needing the NPN -- you use a menu selection to tell the K3 to get CW from DTR and it does it internally. You can also plug a paddle into a K3 to send live. The K2 manual shows how you can use diodes to feed both a computer and a paddle into the keying input. Most other radios don't allow both computer keying and paddle keying, so I use an outboard keyer and diodes to isolate the computer keying from the keyer. The manner in which WriteLog and N1MM send CW causes problems with SO2R (single operator, two radios) operation using this simple setup, and is a good reason for using something like WinKey, which with software that supports it can switch CW between two radios. Most popular contesting software does. For SSB contesting, I'm successfully using N1MM and the stereo out of my sound card to drive two radios, with VOX doing TX/RX switching. My live mic goes to the input of the sound card, and N1MM switches both the live mic and message playback to left or right radio. To listen, I have a headphone Y-cable that gets left ear from one radio and right ear from the other, and use audio gain controls on the two radios to pick where I want to listen. The nice thing about fancier SO2R boxes is that they give you more control of what you're listening to. Also, USB to serial converters are notoriously flaky (CW problems, control problems, crashing computer problems), so having one that is known to work is a BIG plus. Another big plus for the Microham stuff is the high level of support that Joe Subich provides.

Re: [Elecraft] No On/Off for COMP EQ?
Barry, I agree with you. In voice modes it would be very helpful to be able to switch receive and or transmit eq in and out with a button press. Such a capability would also be a quick fix for my problem of inadvertent equalization in data modes. Potentially, equalization save/restore is a complicated issue because one may want to store several different settings, maybe tied to modes. So I can understand if Elecraft wants to explore related issues before giving us something that may have to be replaced later. However, just maybe there is enough justification for in the long run implementing both a quick off/on pushbutton capability and saving/restoring multiple settings. If so, the one could be implemented independently from the other. The simple on/off would, as you suggest, be tied to front panel buttons. The saving and restoring of settings could live under the MAIN menu where the equalization settings already live. Since it takes time and effort to determine one's personal settings, I wouldn't mind having my library of eq settings defined in the Elecraft Utility as one or more settings per mode and downloaded to the radio. Each setting, regardless of mode, would be given a name and be usable with any mode. The Main Menu would show the current settings like now (modifiable from the radio like now), but also show the list of named settings, that could be made active, affecting only the mode in effect when the selection is made. After a computer-saved-and-named setting is made current in the radio/mode, it could again be modified in the radio, and possibly re-saved in the radio (and uploadable to the computer), but creation of a named setting (menu selection in the radio) could only be done on the computer.

Does anyone know if such a home brew AF filter CW response curve setting could be stored using say PF1 button, and then be reset to a flat response using say PF2? Otherwise it gets fiddly and time-consuming to keep tweaking each of the eight filter frequencies. This would be handy 73 Geoff G3XGC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 Filters, Shift Control and RTTY
I have been playing in the WAE RTTY contest. I am mainly using the 250Hz roofing filter with DSP bandwidth at 300 Hz. I occasionally use the 1.8kHz filter with DSP set at about 500 Hz. In either configuration, I find that I have to use the shift control to center signals in the bandpass. Not sure if this is a hardware or software thing, but in any case, I have two issues. One is that the minimum shift value is too large to accomplish what I want to do at the narrow bandwidth, and when I try to use the dual bandpass filter it appears that shift is disabled. Am I missing something(highly likely), or do I have to request that changes be added to the wish list?

Re: [Elecraft] No On/Off for COMP EQ?
There has been much chatter about the K3 EQ lately. I've written a small Windows application that helps to 'manage' the equalizers. This is a work in progress, and I'm not much of a programmer. You should take this to mean: Caveat Emptor! The application is being used by about 20 people now and I'm chasing a couple bugs. 1) It does not behave well when access to the K3 is via N8LP's LP-Bridge. This is NOT an LP-Bridge issue. There is no direct way to read the EQ settings other than simulating button presses and reading the VFO B area. The problem is that the EQ setting displayed on VFO B only appears momentarily and is then replaced with the 'label' for the EQ band. Because LP-Bridge is polling the K3, my app will sometimes miss the data. 2) The app is written in MS Visual Basic 2008 and requires ,NET Framework 2.0 or later. If your system does not have 2.0, it will be downloaded from Microsoft. While this is not in and of itself a problem, I do have one user that is having difficulty that looks like a problem in the Framework - something that may well be beyond my capability to resolve. You can peek at the application and download it here: http://home.roadrunner.com/~n2bc/SW.htm I'm looking for ideas for impovement - some are proposed on the subsequent web page. I am in the process of improving the overall communications error handling, improving the documentation, and looking at other ways to store the EQ settings. No timetable for these as yet. If this little utility is a help, great! I would prefer that any communications regarding the program not be on the Elecraft reflector, but rather direct to me.

[Elecraft] Re: K3 vs HPSDR Mercury
G'day I have been using an Elecraft K3 for about a month now, which is the best performing superhetrodyne/analogue transceiver (with a great DSP back-end) that I have ever used. Once I got the filtering and DSP adjusted right, in terms of pulling weak signals out of noise it was clearly better than my previous FT-1000. I also have a working HPSDR Mercury digital down conversion (DDC) SDR receiver (the Mercury receiver board plus the Ozy communications interface) which use with the PowerSDR software. For those not familiar with SDRs, the DDC type effectively convert radio signals from analog to digital at the antenna socket, using an analog to digital converter. Mercury has a Blocking Dynamic Range of 119dB, which is basically independent of frequency spacing When it comes to pulling weak signals out of noise, on the basis of A/B testing that I've done, weak signals almost lost in noise are easier to understand and less tiring to listen to (more of the latter in a minute) on Mercury than on the K3. I am not an engineer, but a scientific journalist by profession and a CW and contest operator with some 37 years 'on the clock' as a radio amateur. I have been using SDRs for about three years (and am the co-author of the SDR column in the Radio Society of Great Britain's RadCom with my friend Phil, VK6APH who is an engineer and one of the main designers of the HPSDR). I clearly have a personal interest in SDR, but until I started using them was extremely skeptical about their performance. My understanding why the HPSDR sounds better to me than the K3 (and others who have witnessed the comparative tests) relates to the crystal filtering that the latter - and other analogue HF receivers - use. As many on this reflector will know, when noise pulses/spikes pass through a crystal filter, the phase response of the filter changes, depending on the noise frequency. However, when noise pulses/spikes pass through an ADC with a linear response - such as the LTC2208 that Mercury uses - the phase response stays the same, because the ADC treats them in a linear manner. What happens in practice is that on the DDC SDR any 'noise' actually sounds mellow and easy-on-the-ear (!), in a manner that has to be heard to be believed. In the case of an analogue radio like the K3, it seems that even one stage of crystal filtering is enough to cause a phase response to noise that eventually irritates/tires the user (certainly in my case) and makes them want to switch the radio off. I love using the K3 and find it an absolutely brilliant radio, but am looking forward to putting together a HPSDR transceiver to take advantage of the way a DDC SDR receiver deals with noise. Whether top ten contesters find DDC SDRs to their taste will be interesting to see, but as a 160m CW DXer with over 220 countries confirmed, as far as I am concerned they are the way ahead. Incidentally, I think both the Flex SDR-1000 and FLEX-5000 are QSD-type SDRs, rather than DDCs.

Re: [Elecraft] K2: Various Receive Problems
Jon Perelstein wrote: 1. Receive sensitivity is not good. Using the same antenna, and with AGC on: The K2 is somewhat short on overall gain. However that is not the same as receiver sensitivity, which is related to noise, rather than gain. Sensitivity is the minimum signal that will exceed the internally generated noise. It seems as if the AGC is having too much impact since I have to crank the AF Gain almost all the way clockwise to get decent audio volume with the AGC on (both headphones and speaker)? R1 adjusts the AGC threshold. 2. On receive, stations are either there or not there. See below. Along with this, there is no interference from adjacent signals. I'm always hearing the strongest station and only the strongest station at That's good. If there were a way of achieving that which wasn't being used, it would be considered a fault. There is no capture effect with SSB, so the only way of achieving this is good selectivity and good IMD performance. smaller (to be expected with a tighter filter). At FIL3 I can hear only the strongest of stations, and then across an extremely narrow signal bandwidth. Finally, at FIL4 I cannot pick up even the strongest signals. Note that FL1,2,3,4 are selections from a memory. You need to set sensible filter parameters for each of these. 3. As I tune across a CW station's signal, there is no change in audio frequency. Combined with (1), this indicates that the reference oscillator frequency isn't being modified. You should be able to confirm this by using the frequency counter on it. However, there is an explicit check for this during the assembly process and the VFO calibration would fail if it wasn't working. I don't know what happens if you never run the calibration. Note that I do not have the SSB module installed, and I'm not sure if I'm supposed to be able to hear SSB in a bare-bones K-2 without the SSB module installed (although it is my understanding that I should be copy SSB). You do not need the SSB module to receive SSB, and, in fact, if you use the standard SSB setup, FL3 and FL4 settings on SSB do not use the SSB module for receive. -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Firing up K3 SN 2051 -Help
I got some time last weekend, and a bit this week, and s/n 2051 is alive. Assembly was relatively easy, and 98% of the manual is spot - on, so I am very satisfied. The firmware download worked on my Mac the first time and MacloggerDX connected immediately after I set the correct baud rate in the K3 and hooked up a cheap eBay USB to serial cable. I do have an issue, and would ask the group for help. I will call Elecraft again on Monday, but hopefully it is minor and I can resolve tomorrow. All tests went well. I walked though all the settings in Config and Menu. When I did the initial Transmitter Gain test with 5 watts, the 'dummy load' I made turned out to have a lot of reactance.After a quick call to Elecraft, I made a new load, tested it on a simple antenna analyzer, (MJF 239) and it was 50.4 ohms/no reactance across the ham bands. I then re-did the Transmitter Gain at 5 watts, and got 1.0-1 across all bands. So far so good. I used a Yaseu MD-100 mic into the rear mic input, set the appropriate menu (rear input, no bias, mic low). I am now doing the Transmitter Setup on page 26. I configured the xtal via the K3 utility. OK. I cannot transmit audio. The Voice Monitoring setup works, and I can adjust the MON function and hear audio in the speaker and the headphones, so the Mic works. When I go to Mic Gain and Compression Settings, I cannot get any CMP or ALC indications on my meter. If I transmit, the TX light is on, the resistors get a bit warm, but nothing indicated on the SW or RF meter and nothing on CMP or ALC meters. It is if the modulation doesn't work.

Re: [Elecraft] K2: Various Receive Problems
Jon, At first glance it might seem as though your problem may be simply that there is too much AGC. Turn the AGC Threshold down to 3.6 volts as a starter - but I seriously doubt this is the problem, so set the AGC threshod down anyway as a starter just to get that out of the way. The most significant item is your statement that you hear the signals with a constant pitch. That tells me that you may have a PLL/VCO problem and the VCO is not actually on the correct frequency. Check the VCO frequency at the low end of each band against the chart at the lower left corner of the Schematic Key sheet in Appendix B of the manual. To check the VFO frequency, put the internal probe into TP1 and tune to the low end of each band - then in the menu select CAL FCTR to read the VCO frequency. If it differs from the chart by more than 0.040 KHz, you have a VCO/PLL problem. Re-check the PLL range as a first response if this is the case. You could also have a situation where your CAL PLL run was not done correctly - put the K2 bottom panel in place and re-run the CAL PLL routine. If you have rework eliminators in place or have changed C71 to allow for the K60XV installation, you must enter the secondary menu and set D19 to Yes. Failure to do so will create the problem that you state on 40 meters. If these things do not help, ask again, and prepare yourself for Receive Signal Tracing as described in Appendix E of the K2 manual (build the oscillator and the RF Probe). 73, Don W3FPR Jon Perelstein wrote: I just finished building the K2 and am in process of checking it out.

Using the same antenna, and with AGC on: o Without the pre-amp on, the K-2 is nowhere near as sensitive as my K-1, nor is it as good as my FT-897 (but the K-1 is better than the FT-897). o With the pre-amp on, the K-2 is about as good as the FT-897, but still not as good as the K-1. The situation is better with AGC off, as good as or better than the FT-897, but still not as good as the K-1. It seems as if the AGC is having too much impact since I have to crank the AF Gain almost all the way clockwise to get decent audio volume with the AGC on (both headphones and speaker)? 2. On receive, stations are either there or not there. In a correctly operating radio, as you tune across a station's signal, the signal strength starts out lower and then picks up in strength and volume as you reach the station's actual transmit frequency. Furthermore, if two stations are near each other, you typically hear both of them. In this case, if I hear a signal, I hear it at the same volume as I tune across the signal's bandwidth. The perceived signal strength simply does not change. The S-Meter does change value, but not the perceived signal strength in the headphones or speaker. Along with this, there is no interference from adjacent signals. I'm always hearing the strongest station and only the strongest station at whatever spot that my VFO is tuned to. Any other stations are simply not there, as if some sort of really good DSP has completely eliminated all but the strongest station at that point in the VFO (and I mean *completely* eliminated). As you tune across, you can hear the specific point where one station stops being heard and a different one starts being heard. I do not have DSP -- this is a bare bones K-2 without noise blanker or anything else. I have AGC turned off. The problem also appears with AGC on. In addition, it appears in both VFO A and VFO B. I have the squelch turned off. I have checked, and I'm in filter 1 and I'm getting the correct readings from aligning FIL1. When I go to FIL2, there's a similar effect -- except that the bandwidth range across which I can hear the signal is much smaller (to be expected with a tighter filter). At FIL3 I can hear only the strongest of stations, and then across an extremely narrow signal bandwidth. Finally, at FIL4 I cannot pick up even the strongest signals. 3. As I tune across a CW station's signal, there is no change in audio frequency. In a correctly operating radio, as you tune across a CW signal, there is a change in the audio frequency of the signal, until you're at zero-beat, at which time the audio frequency is whatever you've set your sidetone at. In this case, once I hear a signal, I hear it at the same audio frequency across the entire bandwidth of the signal for as long as I'm hearing that signal (see problem 2 above). The audio frequency at which I'm hearing the signal is

[Elecraft] Elecraft CW Net Announcement
Good Evening, According to my little RS clock it is now 0449z. Therefore an hour and 49 minutes ago it was 0300z and 7 PM PST. Hopefully I did it correctly this time :) So tomorrow we meet at z and 0300z. Sounds like a plan. Conditions have been fair to good this last week. It does help my mentor put up a nice beam at 60 feet but the sun has also cooperated. A sunspot is just slipping over the limb of the sun as I write. It may be a sign of things to come; like the beginning of the end of the solar minimum. Weather has been soggy here but I cannot complain. All the wood I collected is keeping the place very cozy. Fire guardian Sam is on watch to make sure the temperature is to his liking. The folks in North and South Dakota do have something they may wish to discuss but I fear they are far too busy digging themselves out of the wind driven snow which fell over a broad swath of territory. I read 80 mph winds sculpted some very large drifts east of and inside of the Black Hills. I lived near Keystone for a few years and went to school at SDSMT as did my father and brother. Normally winters are quite mild there compared to the surrounding areas. My mom had her third child (my sister Dairn) there in 1949 while dad was in school on the GI Bill after the war. She mentioned the drifts reached the second story of the hospital. So these storms do happen but not all that often in Rapid City. Stay warm folks! Please join us tomorrow evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP relay help) 3) Call by time zone (East, Central Mountain, everybody else) Monday z (Sunday 4 PM PST) 14050 kHz Monday 0300z (Sunday 7 PM PST) 7045 kHz Stay well, Kevin.

Re: [Elecraft] K3 AF audio problems
Troubleshooting made easy The Main Speaker, internal and external no longer work. Also, Line input no longer works. Need to use the phone lack to hear any audio. Looks like a trip to the shop.. 73, Scott From: Scott Avery Sent: Saturday, November 08, 2008 6:57 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 AF audio problems Hello All, Today, I was enjoying working some DX etc. All the sudden the AF audio out of my external speaker was all distorted and cracking up. If I advance the AF gain past 12 O'clock distortion happens on the external internal speaker. The Phone output is ok and not affected. Sounds normal at full volume, but NOT main speaker! When changing the audio gain parameter in menu from high to low, no distortion, but the same as 12 O'clock position on AF gain. Also, When powering up, sometimes the main speaker will not work, but phones do. If I cycle the power to the K3, Sometimes, when audio set above 12 O'clock, the audio will sound good for a split second, then the radio backs off the audio automatically, and sounds like crap. Currently running latest beta software. Did revert back to older software, but no change. Any help appreciated! 73, Scott WA6LIE K3 #1993 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 Cool
I've improved some of the visual effects in an update to Cool version 5.1 The new version 5.2 is a ZIP file of the executable alone. Copy it into your existing Cool area (good for K2 or K3) and explode, it's that simple. I've implimented the bitmap graphic that W4SMT is using because it made my old graphic look pretty sad. ;-) http://www.zerobeat.net/mediawiki/index.php/Procat_Cool_for_Windows ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
