Re: [Elecraft] K3 line out only provides left channel audio
Hi Vic, I just checked my K3s and the line OT is indeed a stereo signal. My MENU settings are exactly like yours.

I hear both receivers properly from the headphone jack, but when I connect my phones to the line output, I can only hear the left channel, which is the main RX. Line out is configured for NOR, level is 10. L-R MIX is set to A B, though it shouldn't matter in diversity mode. It isn't a cabling issue, because I have the problem with the phones directly plugged into the LIN OUT jack. I never tried to use this feature before, so I don't know if it worked before.

I have a splitter installed on the speaker output port where one connection goes to powered speakers in the shack and the other connection goes to Remote Rig.

Keep in mind that the K3/Mini-0 controls what is happening at the K3. So the question is what happens at the shack using the speaker volume knob there. When changing the speaker volume at the K3/0-mini you’re also changing the volume of whatever is happening at the shack’s speaker output. Thus, in my case, if the powered speakers at the shack are left on and I change the volume level on the K3/0-mini, it is also changing the volume level going to the powered speakers in the shack. IF LINE OUT is a variable in the CONFIG menu, whatever you change on the K3/0-Mini when in Config mode for Line Out will control the Line Level going out at the K3. As I understand it, setting LIN OUT includes both volume level and the control of volume. Tapping ‘1’ will change LIN Out to = PHOnES, and the audio level is controlled by the AF/SUB gain controls. In addition, you would need to set SPKR + PH to yES so that audio is still provided to the Speaker when Phones is in use. That way, you don’t have to change the audio output at the K3 when using it either by the K3/0-Mini or directly in the shack. However, this also means that when you’re at the remote site, the K3 Speaker will be active when operating remotely. Presumably you could connect your RR Box to this connection instead of speakers and this may indeed provide what you’re looking for. What you’ll need to determine is whether the provided audio Line Level output will be sufficient to drive the K3/0-Mini internal speaker. I don’t know if the Remote Rig audio will compensate for different levels provided by the the K3 speaker jack versus the K3 Line Out jack. It seems to me that the simplest solution to your concerns is simply insert a splitter in the K3 speaker out jack and share the audio with external speakers at the shack along with the Remote Rig box. With the arrangement, there is nothing to plug/unplug when you’re back in the ham shack and the process for speaker audio level control remains unchanged.

Re: [Elecraft] K3 line out
Jim, A shot in the dark here but, is it possible you have line out set to Phones ? Note: Normally, LIN OUT sets a fixed-level receive-only output for main/sub (L/R), compatible with digital modes. Tappingswitches LIN OUT to =PHONES, where the line outputs match headphone audio, audio level is controlled by AF/SUB gain controls, and both RX and TX audio are available.

Re: [Elecraft] K3 line out - Stereo vs Mono
Paul, The short answer is the warnings do not apply to Line Out. Line Out is always stereo but both right and left are transformer coupled (you don't need the Rascal) and the primaries of both transformers contain resistors that would limit current from the DAC to a safe level even of the output of the transformer were shorted.

I use stereo headphones 99% of the time, and for the few times I don't, I'll use the K3's stock speakers . . . My concern was the warning in the manual errata saying that if one did use an external speaker with a mono plug, you could damage the right channel amplifier (unless you made the suggested menu changes.) The Line Out is labelled stereo, and like the eternal speaker one, it has the same triangle icon with an exclamation mark beside it. I was concerned that plugging a mono plug into it would risk the same potential danger as plugging a mono plug into the external speak jack. In a subsequent post, Joe W4TV, says the warnings do not apply to the Line Out because it contains current limiting resistors. That was the main reason for my question. I gave too much background and and lead in . . . I should have simply said: Is it OK to use a mono plug in the stereo Line Out K3's jack? G Now that I have an answer to that I'll go with the recommended K3 RX -- PC TX and K3 -- TX to PC RX (solving the exchange of audio) Next (and hopefully last question): Can I use the RCA PTT IN jack on the back of the rig to key it for RTTY, PSK, JT65, etc.?

Re: [Elecraft] K3 line out - Stereo vs Mono
Paul, Now that I have an answer to that I'll go with the recommended K3 RX -- PC TX and K3 -- TX to PC RX (solving the exchange of audio) I would not bother connecting the RASCAL's receive side. Simply use the stereo audio cable between the K3 Line Out and the PC Line IN. Reserve the RASCAL for the FSK/PTT connection to the K3's AUX. Can I use the RCA PTT IN jack on the back of the rig to key it for RTTY, PSK, JT65, etc.? I prefer FSK to AFSK and hence would rather use PTT instead of VOX. Sure you can. However, if you already have the RASCAL and it provides a PTT connection to the AUX jack, why not use it for PTT even with PSK/JT65A/etc.? I assume the RASCAL is an FSK interface with RX audio from Line Out and FSK/PTT to AUX (DB15HD). If, on the other hand, RASCAL is a simple passive audio box with a serial control port, connect the PTT line from it to the RCA PTT jack and use two stereo audio cables from the K3 to the computer sound card (you don't want to cascade transformers - it's unnecessary and prone to distortion given the quality of the transformers in some external boxes). 73, ...

The speakers question does not have any direct relationship with the MMTTY input. 73, Don W3FPR Hi Don, I provided too much info. I do not want to ever use an external speaker. I use stereo headphones 99% of the time, and for the few times I don't, I'll use the K3's stock speakers . . . My concern was the warning in the manual errata saying that if one did use an external speaker with a mono plug, you could damage the right channel amplifier (unless you made the suggested menu changes.) The Line Out is labelled stereo, and like the eternal speaker one, it has the same triangle icon with an exclamation mark beside it. I was concerned that plugging a mono plug into it would risk the same potential danger as plugging a mono plug into the external speak jack. In a subsequent post, Joe W4TV, says the warnings do not apply to the Line Out because it contains current limiting resistors. That was the main reason for my question. I gave too much background and and lead in . . . I should have simply said: Is it OK to use a mono plug in the stereo Line Out K3's jack? G Now that I have an answer to that I'll go with the recommended K3 RX -- PC TX and K3 -- TX to PC RX (solving the exchange of audio) Next (and hopefully last question): Can I use the RCA PTT IN jack on the back of the rig to key it for RTTY, PSK, JT65, etc.? I prefer FSK to AFSK and hence would rather use PTT instead of VOX. 73, Paul VE1DX __ 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 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 line out
It is by design. Line out is Left for main Rx and Right for Sub Rx. You can set Line Out=Phones and get the audio mixer, but the output level will also vary with the AF Gain control in that case. 73, Lyle KK7P Can some other folks please check their K3 line out and please let me know if you hear the same thing?

Re: [Elecraft] [K3] Line out, speakers, and L-mix-R settings...
I have another question that's somewhat related to my original post. I know it has been discussed many times over; that one should avoid using a mono plug in the SPKRS jack. What I'd like to know though is this: Would it be OK to use a mono plug in either front panel PHONES output, or rear panel PHONE or LINE output without fear of blowing something up? Manual says it should be fine, but just want to get confirmation beforehand that this is OK to do.

Re: [Elecraft] [K3] Line out, speakers, and L-mix-R settings...
Mike, Thanks for pointing that out - I had completely forgotten about that option. I guess it's time I printed out a new copy of the manual! Of course, that changes the answer to James' question #2; if you want the LINE output to be a clone of the headphones output, set CONFIG:LIN OUT to =PHONES. With CONFIG:LIN OUT =PHONES, when the subRX is off, the main RX is in both channels. This setting seems tailor-made for James' situation (listening to speakers through a sound card). For digital modes, as Joe has pointed out, when SUB is on, you use the two channels to feed two independent copies of MMTTY (or other software). You do not want any mixing of the two signals. Also, you do not want the volume control to affect the audio level going into the decoder. If you use the audio pitch as a tuning aid, you want the ability to turn the audio down or to change the balance between the two channels without interrupting the ongoing decoding of both signals. When SUB is off, you only use (or need) one channel in the sound card. The right channel waterfall just goes black when the sub RX is off. You can use two different decoding algorithms on a single signal by running two (or more) independent decoding programs (e.g. two or more separate copies of MMTTY using different profiles) from a single channel in the sound card. 73, Rich VE3KI NF4L wrote: Re: point #2.

Re: [Elecraft] [K3] Line out, speakers, and L-mix-R settings...
Mike, I don't understand why you think there is a problem. I guess I don't understand what you are trying to do. The hardware setup to use both receivers in RTTY is simple, and no different from what you use with a single receiver - a single stereo cable from the K3's LINE OUT to the sound card's LINE IN for receive, a single mono (or stereo) cable from the sound card's LINE OUT to the K3's LINE IN for AFSK transmit, and use RTS on the radio control port for PTT. Or, if you prefer FSK, replace the AFSK transmit cable with FSK and PTT keying circuits to the AUX input. There is no need for a second sound card, no need to cut cables, no need to use a mixer to adjust balance. You set up one copy of MMTTY to receive using only the left channel of a single sound card, and a separate copy of MMTTY to receive using only the right channel of the same sound card. The two operate entirely independently. One decodes the signal from the main receiver, the other one from the sub receiver. If you only want to copy one signal, just don't look at the output from the other copy of MMTTY, or if you find it distracting, just turn SUB off and/or close down the second copy of MMTTY. From N1MM Logger, you can open two Entry windows, one for each VFO, and open a separate Digital Interface window from each Entry window, with separate copies of MMTTY each configured to use the appropriate channel of the sound card. You can receive on both receivers at once, and choose which one to transmit to with the \ key. Or, if you only want to use one VFO, just close down the second Entry window. 73, Rich VE3KI NF4L wrote: All that strikes me as a kludge, but I certainly don't have a better solution. :-( __ 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

On the Mac OS X side, cocoaModem has two independent receive channels in the wideband RTTY and the dual RTTY interfaces. There are two identical sets of user interfaces in a single window -- this gets rid of the window focus problem of running multiple copies of a software modem. There are two cross ellipses, independent mark and space tones, baud rate, and filter settings -- you can even run 75 baud and Mark-only on one decoder, while running 45.45 baud and Mark/Space decoding on the other. In the case of wideband RTTY, there are independent waterfalls. Dual RTTY decode has been in practice in some time now. In the old days, it was done with multiple TU -- this is one of the reasons why normally sane people have multiple HAL ST-8000 in the shack. Just like other modes, having concurrent receive capability on on both the DX and a split pile reduces doubling. Using multiple TU back then required manually scanning the pileup using the VFO knob. If you have a waterfall that is watching the pile, you can pretty much pinpoint the DX's QSX by watching where a signal appears in the pileup waterfall right after the DX finishes sending his exchange. A software modem that is capable of agile transmit can then pounce on that QSX (or find the next hole in the direction the DX is tuning). It used to be like shooting fish in a barrel for people with two RTTY decoders and agile receive (e.g., waterfall tuning) to work the split RTTY pileups. Just ask RTTY DXers who have been using cocoaModem's wideband RTTY interface. But more people have that capability today (what with the Flex-5000 and the LP-PAN), to the point that if you don't have dual decoding and agile tuning capability, you are now at a distinct disadvantage. Of course you need a sound card that has two or more inputs (or a digital interface like the microKeyer/digiKeyer). Some of the cheaper digital interfaces are only wired for a single input channel, even when the codec is a stereo one. 73 Chen, W7AY __ 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

At first I thought it was strange that the audio I was hearing was only coming out of the left speaker rather than both. I checked the manual and after a few minutes of reading realized that under normal situations, activating the SUB would provide the right channel. I then started playing around a bit more, and figured I'd post this question to the group just to make sure I understand how these functions work properly. My experimentation led me to the SPKRS settings which was currently set at 1. With the SUB off, I changed the speaker setting to 2 but no change; audio was still being heard on the left speaker and not the right. Am I then correct in my assumption that the speakers setting has no bearing on the actual number of channels being output from the LINE OUT jack? This brings me to my second question - is there a way to get both L and R channel audio output to the LINE OUT jack just from the main receiver without the SUB being activated? My last question, does the SPEAKERS setting only affect the SPKR OUT jack on the rear panel? According to the manual, leaving it at 1 will only provide one channel of audio. Would setting it to 2 provide both LR channels to the speakers regardless of SUB activation?

Re: [Elecraft] [K3] Line out, speakers, and L-mix-R settings...
James, I hope your daughter is feeling better soon. Re your questions (based on my observations using sound card software on both channels from the LINE OUT jack, and stereo headphones plugged into the SPKRS jack): 1. The CONFIG:SPKRS setting only affects the rear panel SPKRS jack. It has no effect on LINE OUT. 2. None of the audio mixing or level controls has any effect on the LINE OUT signal, as far as I can tell. The left channel always carries the main RX output, and the right channel always carries the sub RX output. The LINE output is raw unmixed audio from the two receivers at a fixed level set by CONFIG:LIN OUT. 3. When CONFIG:SPKRS = 2, the SPKRS jack behaves the same as the headphone jacks. With SUB off, the main RX is in both channels, and with SUB on and the normal L-MIX-R setting, the main RX and sub RX are in left and right channels respectively. Changing the L-MIX-R setting affects the SPKRS the same way as it affects the PHONES output. When CONFIG:SPKRS = 1, the only speaker output is on the left channel of the SPKRS jack, i.e. it disables the right channel output even when SUB is on. If SUB is on, the external mono speaker on the left channel carries audio from both receivers mixed together, the same as the internal speaker. The purpose of the CONFIG:SPKRS = 1 option is to protect the speaker amp if a mono plug is plugged into the SPKRS jack. 73, Rich VE3KI __ 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 - Line Out
Dick, The line out level is fixed by the menu (CONFIG: LIN OUT), and the SPKRS or PHONES output is variable - controlled by the AF gain. They can be used simultaneously. Both/either will work into a high impedance load. I have been using the SPKRS output to drive a soundcard, a mixer or a set of amplified speakers at various times in the past with no problem - just plug it in and set the AF Gain appropriately. Remember there is a HI and a LO setting for the headphone or speaker outputs available in the menu, you may have to set it to LO. Does that meet your needs? 73, Don W3FPR Edward Dickinson, III wrote: Using my K3 with a computer and outboard sound as well sound based programs, both a Fixed-Level and Variable-Level (AF Gain Knob) Line Output simultaneiously could be useful to me.

Hmmm...I'm looking at the multi-platform PortAudio v19 API here: http://www.portaudio.com/docs/v19-doxydocs/structPaStreamParameters.html Currently, we're using PaStreamParameters::channelCount=1, which doesn't offer the opportunity to specify a left or right. With channelCount=2, we could of course get two channels and discard one, as I mentioned. PulseAudio, which is Linux only, doesn't seem to support it either, but I believe ALSA and OSS do. So, if we use a Linux only solution it's possible to specify single-channel capture without discarding one channel, but for the cross-platform APIs, it doesn't seem possible. I know you know more about sound device manufacture than I do, so maybe you can point us at something we've overlooked in PortAudio, so at least we could get portable sound capture support for single-channel input. Even relatively basic USB sound codecs provide control over the input configuration. For the device in question, Griffin iMic, this doesn't seem to be the case.

Re: [Elecraft] K3 LINE Out mixes KRX3 and main output?
For the device in question, Griffin iMic, this doesn't seem to be the case. It does not separate enumerations for independently setting left and right input gain. It does support stereo input, just not two mic/line gain controls. I don't know about the iMic - Chen would though. We've been using TI and Micronas USB sound devices that are directly supported by the native Windows Audio. The TI devices do not have an input mixer - sounds a lot like the iMic - but they still provide two channels of receive audio and an application can hook either channel or force the driver into mixed mono. I've used both the TI and Micronas based devices in stereo (separate left/right) for dual receive or right only (sub RX only) with MMTY, MMVARI, and MixW. Unfortunately, I see the issue with FLdigi ... it uses mixed mono with either the TI or Micronas CODECs. I can handle that by turning down the input level to the CODECS (manual gain controls) but that still does not permit dual receive. Interestingly, DM780 handles both the TS and Micronas in left channel (Main RX) only. 73, ... Joe, W4TV -Original Message- From: Leigh L.

Joe Subich, W4TV wrote: It doubles the data transfer to capture both sound channels and discard one. Why would you bother to capture both? Your software should be able to select left, right or mixed input from the soundcard. Hmmm...I'm looking at the multi-platform PortAudio v19 API here: http://www.portaudio.com/docs/v19-doxydocs/structPaStreamParam eters.html Currently, we're using PaStreamParameters::channelCount=1, which doesn't offer the opportunity to specify a left or right. With channelCount=2, we could of course get two channels and discard one, as I mentioned. PulseAudio, which is Linux only, doesn't seem to support it either, but I believe ALSA and OSS do. So, if we use a Linux only solution it's possible to specify single-channel capture without discarding one channel, but for the cross-platform APIs, it doesn't seem possible. I know you know more about sound device manufacture than I do, so maybe you can point us at something we've overlooked in PortAudio, so at least we could get portable sound capture support for single-channel input. Even relatively basic USB sound codecs provide control over the input configuration. For the device in question, Griffin iMic, this doesn't seem to be the case.

It does not separate enumerations for independently setting left and right input gain. It does support stereo input, just not two mic/line gain controls. I don't know about the iMic - Chen would though. It depends on the generation of the Griffin Technology iMic. I have three generations of iMic, dating back from more than 5 years ago. The are the grey disk shaped ones, not the current-generation white ones. The oldest one had a 20 bit input codec, with no digital attenuator, no left, no right, no Master. The next generation is also 20 bits, but it has independent left and right attenuators (as seen from Core Audio -- I don't use Port Audio), but no master attenuator. Both of the above have 20 bit codecs in them, but uses the USB Audio Interface class and you can only see 16 bits (they don't need special drivers, but you also don't see 20 bits, HI). After that (and I believe it is true with the white bodied ones) they went to a 16 bit codec. Mine (still a gray body) only has a master level control but no individual left and right controls. If you are using Mac OS X, the easiest thing is to launch the Audio MIDI Setup utility that is in /Applications/Utilities. Audio MIDI Setup also uses Core Audio. There are three slider associated with each sound card's volume, a Master slider, and channels 1 (left) and 2 (right). If a control is not available, it will be grayed out. The microKeyer II, for example, has the Master control grayed out but the left and right channels are independently adjustable. My digiKeyer uses the Burr-Brown PCM2902; when using Core Audio, there is no master, left nor right controls. 73 Chen, W7AY __ 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 LINE Out mixes KRX3 and main output?
Sorry for the confusion on the sound card side: It's a stereo input, but I don't get software control of the balance or independent gain. It's not on Windows. The Griffin iMic device specs say stereo, but the driver appears to be supporting only mono gain controls. If I go to LIN OUT menu and tapping button 1 to get =PHONES then I can use the audio gain controls to control the mix, but if I use NOR mode LIN OUT then it's always mixed. Probably easiest for me to make a cable than (a) fix the driver or (b) ask for firmware changes. Leigh/WA5ZNU Leigh L.

Re: [Elecraft] K3 LINE Out mixes KRX3 and main output?
I think the right place to fix it would be in whatever software is using the captured audio - the driver is OK, but the software needs to let you select channels you want.

Re: [Elecraft] K3 LINE Out mixes KRX3 and main output?
I took a quick look at it and I think I need to capture 2x the data and discard half of it in order to get just one channel out of the sound device. So I think fixing it in hardware makes more sense...

Re: [Elecraft] K3 LINE Out mixes KRX3 and main output?
Yes, so my request would be to be able to mute one of them. Using a cable to connect only left is the best solution if the rig can't mute one. It doubles the data transfer to capture both sound channels and discard one. I agree though it's not that high priority.
