Re: [Elecraft] K3 and PSK 31
Andy, I did not see any response on the reflector, so I will try. First of all, you need a soundcard. If you have installed the KIO3B in that K3, there is an internal soundcard in the K3 that can e used. If the KIO3 has not been upgraded, you will need a soundcard external to the K3. Either an internal computer soundcard or an external one. The computer must send audio to the K3 Line input and receive audio from the Line Out of the K3. HRD (or Win4K3 or other applications) will provide rig control functions without the audio paths. For instance, PSK31 (and other data modes) sends audio tones to the K3 via the computer soundcard, and receives audio tones from the K3 for decoding. Set the K3 to DATA A submode (AFSK A for RTTY), and during receive, adjust the computer Line In (or Mic) level to give you a good waterfall display. You can also adjust the LINE OUT level in the K3 menu. For transmit, adjust the soundcard Line Out (or Speaker) slider to about 75% of full and then in the K3, set the MIC SEL menu to LINE and adjust the "MIC GAIN" (actually LINE IN gain) so you have 4 bars illuminated solid on the K3 ALC display with the 5th bar flashing. Adjust the desired power level with the K3 power knob. Ignore the internet advice (and some software applications) to set the power to max and adjust the power output with the audio level - that does not work well with Elecraft gear. That advice is for other transceivers which do not control the power output by actually measuring the power level and making adjustments to make the power equal to the requested power level. Use the instructions in the K3 manual - paraphrased above. 73, Don W3FPR On 3/12/2017 11:19 PM, abulling...@comcast.net wrote: I've really been enjoying my new used K3.

[Elecraft] K3 question, PSK and AM filter option from G4HUE
Happy Xmas guys and a healthy and prosperous New Year to all. I am a recent convert to the K3 with model 6990. I am primarily a data mode operator (PSK31 etc. etc.) and my K3 has the 2.8KHz and 250Hz 8 pole filters fitted and let me say its doing a very fine job too. I use HRD version 5 which appears to force the sound card to sample at 8KHz (in my case it’s the Signalink USB). My question is that I would like to be able to simultaneously decode more than 2.8KHz (HRD is limited to 3.9KHz) of the ham band at once. I have thought about fitting the 6KHz AM filter (there not being a 4KHz filter available). One part of me says that would work just fine and the other part of me says “don’t be silly” there will be 3KHz of LSB and 3KHz of USB and it will all go horribly wrong. I guess someone out there has tried and can tell me which of my premonitions is correct?? As a suplementary will this be limited by any audio filtering in the K3, I seem to recall reading that the K3's audio is limited to a bandwidth of 4.2KHz but of course I can find the reference now!! Thanks in advance guys.

I guess someone out there has tried and can tell me which of my premonitions is correct?? I don't think your premonitions are correct abut things going terribly wrong. However, my feeling is why bother? The K3 transmit audio in DATA A rolls off significantly below roughly 300 Hz and above 3000 Hz (maybe 200/2900 Hz it's been a while since I tested it) thus any RX bandwidth above 3 KHz would be receive only. The 2800 Hz/8 pole filter is about 2900 Hz or slightly wider at the -6DB points in any case and will have significant response on the filter skirts so you will certainly find response to 3.9 KHz if you set the DSP to allow it (even though the response may be down a fair bit). As a suplementary will this be limited by any audio filtering in the K3, I seem to recall reading that the K3's audio is limited to a bandwidth of 4.2KHz but of course I can find the reference now!! The DSP is limited to approximately 4.2 KHz output. The DAC which feeds the headphone and speaker outputs is followed by a lowpass filter at 4.2 KHz to remove clock leakage and other artifacts. Although the DAC which feeds the Line Out does not also include a LPF, the DSP programming is the same including the 4.2 KHz cutoff. 73, ...

Re: [Elecraft] K3 RTTY - PSK D
Rich, Yes, I have RTTY working in AFSK mode. I am trying to make it as LEAN as possible. If MMTTY can bring the FSK as a digital signal which can be fed into the K3 as digital signal (0/1) that would be nice and Lean. Just as N1MM and CW over one cable for the K3. Of course I can use two cables, one for N1MM rig control and one for MMTTY and feed that to the ACC connector using an optocoupler or so. Again, not as lean as the nice CW solution. 73 Arie PA3A Op 23-1-2011 0:37, Richard Ferch schreef: The MMTTY/EXTFSK combination can use DTR on a serial port for FSK keying, but I have no idea whether EXTFSK would work through LP-Bridge.

Re: [Elecraft] K3 RTTY - PSK D
Arie, I assume you are asking whether it is possible to use the RS232 port to send FSK RTTY in FSK D. If so, the answer is yes. Below are three theoretically possible methods - only the third one works, and only from a limited selection of software, but it is possible. The K3 does not accept direct ITA2 (Baudot RTTY) FSK keying on DTR or RTS, and even if it did, there is no software that I know of that would be capable of sending FSK using the same serial port as is used for radio control. The K3 can accept Morse code input and convert the Morse code to ITA2 RTTY in FSK D, but only from its internal keyer (either from paddles or from one of the memory keys on the front panel). The CW-to-DATA converter does not accept CW from an external straight key input, from an external keyer such as a Winkeyer, or from DTR or RTS on the RS232 port. However, there is a software command that you can use to send ASCII text to the K3 to be transmitted in FSK D. It's the KY command (see the Programmer's Reference). I believe that the K3 Utility and G4ILO's KCOMM software can use this command, but most other RTTY software (such as MMTTY) cannot. So, by using KCOMM or the K3 Utility you can send FSK RTTY from the K3 without an FSK keying circuit connected to the AUX connector. 73, Rich VE3KI PA3A wrote: I can control the K3 over the rs232 cable.

Re: [Elecraft] K3 RTTY - PSK D
Arie, You will have to ask Larry Phipps if that MMTTY stream is implemented in LP-Bridge. RTTY via DTR is possible, but would require the one transistor keying circuit to drive the PTT-IN pin on the K3s ACC connector. Of course, LP-Bridge may or may not support DTR through its interface. 73, Don W3FPR On 1/22/2011 5:52 PM, Arie Kleingeld PA3A wrote: Thanks Rich, clear answer. Well... The idea was to use LP bridge.

[Elecraft] K3 and PSK
I am trying to set up my computer, etc to use HRD, DM780, and my K3. I can tune around and receive and decode psk and rtty just fine with DM780, but when I go to send, it goes in to transmit but has no power out.

Re: [Elecraft] K3 and PSK
Mike, In answer to your question, you can tell whether there is modulation or not by using the K3's Monitor function (the MON level must of course be above zero for this to work). As for the answer to the question you didn't ask, one possible explanation for the lack of modulation is that your input level is set to zero. If you are using DATA A mode and your sound card's output is connected to the LINE IN jack, you can adjust the LINE level using the MIC gain control. (If rotating this control adjusts the MIC level in DATA A mode, you can correct this by setting MAIN:MIC SEL = LINE while the radio is in DATA A mode. This will not affect the MIC SEL setting in voice modes.) A level setting somewhere around LINE 10 should get some modulation into the radio. The way to set the correct levels for this control, together with the sound card output level controls, is to set the K3's meter to read ALC and adjust the levels until you get 4-5 bars of ALC reading while transmitting. In PSK31, for the cleanest signal you should set the PWR control to 50 watts or less (5 watts or less on a K3/10). 73, Rich VE3KI AI4NS wrote: I am trying to set up my computer, etc to use HRD, DM780, and my K3.

Re: [Elecraft] K3 KComm PSK D / FSK D Question
Joe has already provided one reason why there is little point in using the computer soundcard for receive and the K3 DSP for transmit. As he said, it would be much more difficult to ensure that TX and RX are both on precisely the same frequency as if the soundcard was doing both, and they do need to be spot on or the other guy will miss the start of your over while his software locks on to it. One of the changes I will be implementing in the next version is a waterfall to allow CW signals to be spotted by clicking on a waterfall. However, that is useful because a) KComm does not decode CW for itself (I have given up trying to make that work) and b) it is also useful for people who decode CW for ear. My experience has shown that the computer sound card PSK31 Core DLL does a better job of decoding data when signals are weak than the K3 DSP does. In other words, if you have a computer sound card available it is pointless to use it for just a waterfall and not let it do the decoding as well.

Agreed, this is important. The way I've tried to ensure the RX TX frequency is the same is to select the soundcard option in KComm, manually switch the K3 back to PSK D. If set up correctly I can then see the same text decoded via KComm's soundcard DLL on screen the K3's own text decoder. I've successfully made contacts this way, so am assuming the TX/RX frequencies are the same (if not, it's a K3 problem, not a KComm one!). Of course I loose the KComm's TX window macro capability doing this so I have to TX via the K3 macros or the paddle which is awfully clunky.

[Elecraft] K3 KComm PSK D / FSK D Question
I'm either missing something or I have a feature request for KComm, depending on whether I have misunderstood how to use the software! I've been looking for a contest / general purpose logger for data modes from the K3 that can make use of the K3's PSK D and FSK D modes for RTTY and PSK31, i.e. using the K3 to generate the RTTY or PSK signals and not the computer soundcard. This is something that, at least with my basic PC, the K3 seems to be much better at as well as eliminating an audio cable from the PC to the K3. KComm does this very well. On the receive side, there's a problem. I've read understand the reasons why KComm cannot yet use the decoded RX data from the K3 on the serial port (big shame, BTW). But even so, tuning PSK31 signals is very fiddly using the K3's CWT hopeless in a contest situation. I was hoping to be able to use the PSK engine and the waterfall within KComm to facilitate tuning in signals and for text decode whilst retaining the excellent FSK/PSK D TX arrangement that KComm has implemented. However, as soon as the soundcard option is ticked in the settings, the programme seems to now only allow TX also via the soundcard. So to my question: is it possible for KComm to use the PC soundcard for RX tuning and data decode, whilst retaining the K3's data TX capabilities via the serial port? I think even after it hopefully becomes possible to separate the K3's decoded text and radio responses on the serial port, some form of waterfall aid to tuning and band monitoring will still be extremely useful within a logging / control programme, then requiring an input to the soundcard anyway.

Re: [Elecraft] K3 KComm PSK D / FSK D Question
I may be missing something, but I think it could work in the same way as KComm behaves now. Unlike other soundcard software, which simply decodes in the DSP at whatever frequency in the waterfall is selected, KComm retunes the K3's VFO so the signal is centred in the waterfall. Therefore it is always decoding at a known fixed frequency. There may be an offset from the TX frequency but it should be predictable and can therefore be compensated for. The quick test would be to see if the soundcard decoded text coincided with the K3's own decoded text. Unfortunately it's difficult to check because the K3 PSK31 text decode is disabled in DATA A. The usual caveats about misuse of AFC and NET would still be relevant. I can see how it needs to be implemented from a system perspective, but not being a programmer, I don't know how to do it! 73 Ian G4FSU 2009/2/28 Joe Subich, W4TV li...@subich.com Ian, So to my question: is it possible for KComm to use the PC soundcard for RX tuning and data decode, whilst retaining the K3's data TX capabilities via the serial port? Although it might be technically possible for KComm to be modified to use the PC soundcard for turning and PSK31 decode and the PSK-D mode for transmit, I do not thick you would like the results as the transmit and receive frequencies would quite easily diverge since PSK-D transmits at a fixed 1050 Hz tone frequency. Zero beat is quite critical with PSK modes. As little as 10 Hz deviation between transmit and receive frequencies can result in walking the band if AFC/Net are in use or no copy if the other station is not using AFC. 73, ...

Re: [Elecraft] K3 and PSK
Lyle Johnson wrote: If you really must do this, you should probably set CONFIG:TX ALC OFF once you've adjusted your power level using the PWR control. Otherwise the ALC system will see the Tx output not being what was requested and will increase the gain, leading to power creep and all sorts of other problems. And a side effect is that when you next request power, you'll get alot more than you asked for because the ALC loop now believes the Tx chain gain is far less than it actually is. The ALC 5 bar level is the level to which all transmit system gains are balanced -- at least those that use any sort of audio as the ultimate source. If that's how it is supposed to work, why doesn't it REDUCE the gain when it sees the Tx output being MORE than what is requested? Because it doesn't. That's the point. In the latest Beta code I tried very hard to balance levels so that CONFIG:TXG VCE can be set to 0.0dB. This might have been affecting your power control issues. The trouble with this is that TXG VCE is an SSB mode adjustment. I don't have excessive power in SSB mode therefore I don't wish to reduce the TXG VCE. If there was a separate TXG setting for DATA as others have suggested on previous occasions, this might be the solution. Although at present, the minimum -3.0dB setting is not quite sufficient to get the output down to the correct level. quote? I did extensive testing with Olivia (125/8 through 2000/64) and WSPR to be sure the power levels are as requested and stable. At least on my K3, they seem to be. I check the power using a TUNE signal (pure sine wave). I would expect the output power to be the same in DATA as if the same tone is transmitted in SSB mode, and the same as when keying down in CW mode. - Julian, G4ILO.

Re: [Elecraft] K3 and PSK
Robert, I don't know of any step-by-step instructions, the whole picture is complicated because of the variety of computer soundcards that could be used. As far as the K3 is concerned, the procedure is simple - adjust the line-in gain setting, much as you would with the mic gain. Yes, the level can be set using TX TEST - and it is best if you do it that way because you don't both other hams with on-the-air signals. Normally there are two controls to work with - the LINE gain setting in the K3 and the Line-out soundcard controls on your PC. The output from soundcards vary, so you will just have to manipulate them and see what happens. For starters, I would suggest setting the soundcard line-out level at the slider midpoint, then adjust the LINE gain setting on the K3. You should strive for settings that will allow you some later adjustment room if possible, but if your soundcard output level is very low or very high, that may not be possible. You want to have a maximum of 4 bars of the ALC meter illuminated. 5 bars is where the 'real' ALC comes into operation, and the bars below the 5th act more like as a 'VU meter'. You want the level as high as possible without actually driving it into the ALC region (5th bar).

It really would be impossible to do this because the output level and input sensitivity of different sound cards will vary. The output even varies from one program to another. The receive side is easy enough, and can be adjusted until you see a faint moving background on the waterfall with a quiet band, and the signals stand out clear. On transmit I would suggest that you just increase the audio going in to the radio using a combination of the slider on the PC mixer and the MIC control, until the output on the power meter reads the power you want. Ideally you should do this while getting the software to send a Tune signal - a pure tone, and aim for 50W or less. A modulated PSK signal should give a reading of less than half the peak power, so no more than three bars on the power scale. I'm unhappy with the advice to set the level to 4 or 5 bars on the ALC scale because when I do this my K3 puts out twice the power set on the POWER control making it far too easy to overdrive the PA. I prefer to adjust the input level until the output power matches what it says on the power control. Then I can use the power control intuitively to set the power the same way it works in CW and SSB modes. For me, the amount of input needed to do this is some way below the point at which ANY ALC blobs appear. - Julian, G4ILO.

Re: [Elecraft] K3 and PSK
Don, Lyle, Greg, You guys are fabulous! Thank you. I would really like to make sure I have things tied down for Feb. 73's Rob KE7VHF Robert Hall www.RobertHall.com On Thu, Jan 29, 2009 at 10:42 AM, Don Wilhelm w3...@embarqmail.com wrote: Robert, I don't know of any step-by-step instructions, the whole picture is complicated because of the variety of computer soundcards that could be used. As far as the K3 is concerned, the procedure is simple - adjust the line-in gain setting, much as you would with the mic gain. Yes, the level can be set using TX TEST - and it is best if you do it that way because you don't both other hams with on-the-air signals. Normally there are two controls to work with - the LINE gain setting in the K3 and the Line-out soundcard controls on your PC. The output from soundcards vary, so you will just have to manipulate them and see what happens. For starters, I would suggest setting the soundcard line-out level at the slider midpoint, then adjust the LINE gain setting on the K3. You should strive for settings that will allow you some later adjustment room if possible, but if your soundcard output level is very low or very high, that may not be possible. You want to have a maximum of 4 bars of the ALC meter illuminated. 5 bars is where the 'real' ALC comes into operation, and the bars below the 5th act more like as a 'VU meter'. You want the level as high as possible without actually driving it into the ALC region (5th bar). Robert Hall wrote: Is there somewhere where I might find a more exhaustive step by step discussion of seting up sound levels on the pc while connected to the K3. I may be a little dense and have not felt entirely comfortable with what I have read in the manual. Maybe this discussion might include config menu items and what the different settings would do to effect the way the K3 behaves with different modes? A good example of this is the idea of setting the number of bars for pc output, correct? Would this be done for actual rf output or would this be done via setting tx to test? thank you, Rob KE7VHF Robert Hall www.RobertHall.com http://www.roberthall.com/ http://www.RobertHall.com http://www.roberthall.com/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 and PSK
I'm unhappy with the advice to set the level to 4 or 5 bars on the ALC scale because when I do this my K3 puts out twice the power set on the POWER control making it far too easy to overdrive the PA.

Then I can use the power control intuitively to set the power the same way it works in CW and SSB modes. For me, the amount of input needed to do this is some way below the point at which ANY ALC blobs appear. If you really must do this, you should probably set CONFIG:TX ALC OFF once you've adjusted your power level using the PWR control. Otherwise the ALC system will see the Tx output not being what was requested and will increase the gain, leading to power creep and all sorts of other problems. And a side effect is that when you next request power, you'll get alot more than you asked for because the ALC loop now believes the Tx chain gain is far less than it actually is. The ALC 5 bar level is the level to which all transmit system gains are balanced -- at least those that use any sort of audio as the ultimate source. In the latest Beta code I tried very hard to balance levels so that CONFIG:TXG VCE can be set to 0.0dB. This might have been affecting your power control issues. I did extensive testing with Olivia (125/8 through 2000/64) and WSPR to be sure the power levels are as requested and stable. At least on my K3, they seem to be. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 and PSK
Setting up my K3 for PSK31. Using PC with on board sound. (Intel Integrated Audio). Stereo cable from K3 to sound card. I am looking to adjust ALC for 4 bars using the line in adjustment. I find that a level change of one unit on K3 (i.e. 5 to 6) changes ALC from zero bars showing to 5 bars showing. Adjusting sound card levels move the onset point but doesn't change the behavior.

Re: [Elecraft] K3 and PSK
Ron, I would suggest that you reduce the soundcard output level and increase the K3 line in setting for smoother control of the audio level. I run my K3 line in at 12 to 13 and adjust the soundcard level to achieve the proper number of ALC bars (4) - my soundcard controls are at the mid-point when it is adjusted correctly. I am using an internal SoundBlaster Live 24 soundcard. Your results may depend on your particular soundcard as well as the K3 settings. 73, Don W3FPR Ron W3ZV wrote: Setting up my K3 for PSK31.

[Elecraft] K3 Running PSK 31
Bruce, I don't know what software you are using on the K2/K3, but most software that I have used allows you to select 'PTT Via CAT Command' on the serial RS232 input which doesn't require setting DTR/RTS. I have had very good luck with this configuration. 73 Dave KD1NA Due to the different levels present between the Line In and the FP or RP mic inputs you will need to adjust the VOX to a higher level. When I tried this I had to almost set the VOX to maxbut not quite. Why use VOX at all? If you have the radio connected to a computer using a soundcard program why not utilitze the RS-232 line already connected? You can do this by setting the PTT-KEY CONFIG menu item and making the correct DTR/RTS settings in the software you are using. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
