[Elecraft] K3 Line out level and Digikeyer
For digimodes like WSPR I use a Microham Digikeyer and set the K3 Line Out level to 10, which is the maximum recommended before the possibility of distortion is introduced. At this level I have to set the Digikeyer RX input control to max to obtain proper decoding etc and being at maximum leaves no room for further adjustment. I usually like to set in/out controls to around 50% but in this case it would mean setting the K3 Line Out to around 40 to be able to reduce the Digikeyer input by 50% So, is Line Out level 10 still the max before distortion/saturation of the output transformers occurs or is there any headroom. If 10 is still the number then fine, as the object is to provide the cleanest signal to the DigiKeyer soundcard even if the input does have to be set to max. 73 Trevor G0KTN __ 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] [K3] KDVR3
Elecrafters, i just read the instruction manual for the KDVR3, there is no hint how the audio is routed. Questions: 1. Is the audio from the mic routed through the tx-eq when recording? 2. Or is it routed through tx-eq when played back? (makes sense) 3. Is RX-Audio routed through rx-eq when recording? (makes no sense) 4. Is recorded rx-audio routed through tx-eq when played back?

Re: [Elecraft] K3 Line out level and Digikeyer
Trevor, If you have AGC enabled in the K3, the Line Out level can be increased considerably beyond 10.

[Elecraft] K2 - CONTROL PANNEL FREEZE UP (K7CJA)
I have a K2 with a KPA100 and KAT100 in a separate enclosure. It had been working on my lossey loop but I decided to try a ground mounted Hi-Q 4/160. After connecting the antenna, I began trying to tune to the various bands. It seemed to be tuning to a low SWR when the control panel just froze up. The VFO would not change the freq and none of the buttons functioned. I turned it off and on several times and came up with the full elecraft in the LCD and then the last freq I was on. The control panel was still frozen. I then tried to reset. That did not work. Now it just goes through the POST (full elecraft in the LCD) and seems to go into transmit (dummy load connected) with a high pitched tone and hangs there. Any suggestions would be greatly appreciated. 73, Chris Amyes, K7CJA -- View this message in context: http://n2.nabble.com/K2-CONTROL-PANNEL-FREEZE-UP-K7CJA-tp3749758p3749758.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] Tuning Rate
Builders of the STAR rave about the tuning scheme Peter Rhodes has in it. I built MY version of STAR with my own software and couldn't get my variable rate stuff to work very well. KK7P is familiar with it, and no doubt he can do better than I did. In any case, like everything else under the sun in the K3, you don't have to get in a big uproar about this: just add a VARIABLE choice to the tuning rate menu and you can decide whether you like it or not. Personally I was thinking it would be nice to have the FINE button choose 1 Hz tuning rate, and COURSE be variable.

Re: [Elecraft] K2 - CONTROL PANNEL FREEZE UP (K7CJA)
Chris, Keep that dummy load attached, and set the power knob to zero. That K2 is going into transmit, so you want to protect the PA from harm while figuring out what is going on. Remove anything that may be plugged into either the paddle jack or the mic jack and try again. If it still goes into transmit, remove the top cover and on the Control Board, check the collector of Q1 - it will be between 7.5 and 8 volts if the K2 is in transmit. Also, check the collector of Q2, which should be at 7.5 to 8 volts during receive, If both Q1 and Q2 have voltage on the collector, it is trying to transmit and receive at the same time, so keep the power on intervals short if that condition is present. Assuming you have the 8 volts at the collector of Q1 but near zero at the collector of Q2 (proper for transmit state), then check pins 29 and 30 of Control Board U6 (the microprocessor) - both should be higher than 4 volts (close to 5 volts). If one or both are at a low voltage, there is something holding the dot or dash lines low, and you should be able to locate it with an ohmmeter and visual inspection for solder bridges or stray wire clippings. If you have both transmit and receive 8 volt lines (collectors of CB Q1 and Q2), then check the gates of CB Q3 and Q4. For receive, the gate of Q4 should be high (4.5 to 5 volts), and the gate of Q3 should be near zero. If these last conditions are true, the microprocessor outputs for transmit and receive are correct and the most likely failure is a shorted Q3. Let us know the results of those tests. 73, Don W3FPR CJA wrote: I have a K2 with a KPA100 and KAT100 in a separate enclosure.

Re: [Elecraft] K# and data modes
In AFSK the K3 is already reading the mark frequency just as in FSK. If you work someone in FSK and then chance to AFSK you should still be on the same freq. This is because even in AFSK the radio is using the pitch combination so that you still have the dual peak filter available. In AFSK you still need to make sure the K3 is using the same pitch tones as the soundcard software. If the software is set for 2125 and the K3 pitch AFSK is set for 915 you are not going to see very much output. This is one of the more common issues when someone is having a problem with AFSK. - 73, Greg - AB7R Whidbey Island WA NA-065 On Thu Oct 1 11:55 , Julian, G4ILO sent: Mike-39 wrote: Hi Julian - Direct keying = FSK Audio keying = ASFK See http://www.aa5au.com/gettingstarted/rtty_start_intro.htm for some pro/con arguments re: RTTY.

Re: [Elecraft] K# and data modes
Mike the K3 does not need any extra interface to operate sound card modes with a PC. A couple of ordinary 3.5mm to 3.5mm stereo cables (to/from a sound card) and a standard serial cable between your PC and the K3 works perfectly. No special settings, no need for VOX, separate line in/out levels to leave your mic levels alone, EQ bypassed on data, you name it the K3 does it. The Ham Radio Deluxe software will key the K3 via serial command and it's freeware. The K3 is probably one of the easiest radios to interface for data modes, having built in isolation transformers and a command set which allows serial RS232 transmit/receive commands to operate it. 73 Dave, G4AON K3/100 #80 -- Has anyone used a Buxcomm Rascal interface with the K3?

In DATA mode: FSK D (Direct), AFSK A (Audio), PSK D (Direct) and DATA A (Audio; PSK, etc.). Built in PSK, RTTY, and CW text decode/display. What I mean by offset is having to tune xnnn Hz up/down from the carrier frequency. I'ts just one more mental step that slows me down, and it's un-necessary. I don't understand what your comment about the 400-2400Hz means, unless it's the offset I'm talking about. I've never operated AFSK, so I may be using the wrong terminology. I don't know about unusually difficult. Certainly not as easy as using AFSK (as even the article you referred to stated) as it requires a special interface and extra connections to the ACC connector. But if that's the way you want to do it, I think Joe has given you the answer. RTTY was traditionally generated by directly frequency shifting the carrier because the two tones directly correspond to the state 1 or 0 of the serial data stream when text is transmitted using 5-bit ASCII at 45.5 baud. PSK31 is a more complicated modulation scheme. According to the manual, the K3 can generate PSK31 using FSK IN as well. That is something unique to the K3 and I don't know what software supports that method of doing it or whether anyone has ever tried it. The manual doesn't state what bit length / baud rate you must use in that case. The reason I don't use the direct method is that I simply find it far easier to tune a signal in by clicking with the mouse on a waterfall display anywhere within the 400 - 2400Hz range of the passband (or whatever filter width you are using) and letting the software AFC ensure you are accurately netted than using the VFO to tune the signal to the precise frequency that is used when the mode is generated directly. I appreciate that you may be used to working RTTY that way (I did too, in the years before sound cards) but having got used to using a waterfall for PSK31 the old way of doing it just seems unnecessarily difficult (and it's much harder to tune in a PSK signal using the VFO than a RTTY one.) - Julian, G4ILO.

Re: [Elecraft] K# and data modes
The Rascal already has audio lines wired in, but since there doesn't seem to be audio in or out on the ACC connector, I need to add another set? OK, you appear to have an older RASCAL instead of the current ones with all connections on the DIN-5. I'm working from data on the BuxComm web site. If the audio cables are captive there's not much you can do. The ACC connector I'm referring to is the DB15HD ACC connector on the K3. The DIN-5 is the RASCAL Connector. You need to connect the audio connections to the Line In and Line Out jacks on the K3. This is the audio from the rig to the computer? Should that be Line IN? Pins 4 2 on what? Pins 2 and 4 on the DIN-5 on the RASCAL (at least the current ones). Since the K3 has transformer isolation you can simply connect standard stereo 3.5mm audio cables from the K3 Line Out jack to the Line In jack on the computer and the Lin Out jack on the computer to the Line In jack on the K3.

Re: [Elecraft] K3 command mode default k30 k31
Joe, I beg to differ. The K3 does provide the information on the command state via the 'K2n;' command and the 'K3n;' command. The K30 state is clearly documented as the default. I repeat, any software that needs to issue K31 commands must assure that the K3 is capable of accepting those commands. This is a task for the programmer who says they support the K3 command set. IT IS NOT A MATTER OF NOT CHANGING THE STATE OF THE RADIO - the situation is that the software is trying to issue a command that requires the K31 state. The command cannot be received if the radio is not in the K31 state - so either the software must use an alternative method or it must set the K31 state. If the software must restore the radio to the K30 state afterwards (to be good programming) than by all means, issue the K30 command at the end of the process. That fact that other radios 'do it differently' is not a reason for software which supposedly supports the K3 command set to make assumptions about the state of the K3. I do come from a long background that says any software that makes assumptions (without checking) is faulty programming. 73, Don W3FPR Joe Subich, W4TV wrote: Don, That sounds like a programing deficiency in the Microham MK2. The fact that the K3 defaults to K30 on power on is documented in the Programmer's Reference as default. That's uncalled for. The K3 RTTY mode is ambiguous in its default configuration. There is no way for software to distinguish among the four data sub-modes with the default K30 response set. The hallmark of good software is that IT NEVER CHANGES THE STATE OF THE RADIO UNEXPECTEDLY. This is particularly true for microHAM Router since it has to interoperate with a multitude of logging and data programs - some of which require K30 mode and some of which use the K31 configuration. The appropriate fix would be for the data sub mode report to be present in the IF (autoinformation) report at all times - but that's not the way the K3 currently operates - or for the K3 to add two new modes to indicate audio based data submodes (AFSK_A or DATA_A) like Yaesu did in their Kenwood like protocol for the FT-9000/2000/950/450. The lack of information on AFSK/PSK vs. FSK simply means that this one feature of the microHAM interfaces (DigiKeyer, microKEYER, microKEYER II) is not supported with the K3 because the K3 fails to provide the necessary data. Except for the K2 and K3 (and Flex-Radio), the RTTY mode in every other transceiver manufactured in the last 20 years (and all Kenwood transceivers except the TS-440) is always FSK. With the K2 RTTY is AFSK and with the K3 RTTY is ambiguous. 73, ...

[Elecraft] K2 Shuts down on boot up
Yesterday evening after making a psk31 contact, then just listening for a couple of hours my K2 shut down. At the time my wife was working with the shack's computer. So I disconnected EVERYTHING from the K2 and turned it on using only the internal battery. It would start the boot process, get to the frequency display and shut down. Tonight I took the top off, disconnected the IO and DSP boards. Looked for obvious problems and tried again. Same result. There is just enough time during this process to tap MENU while the ELECRAFT display is on. The display then shows 2.04r 1.09 Then as usual as soon as the frequency comes up the unit shuts down. Any ideas? Nothing appears to have overheated, nor can I detect any warm components.

Re: [Elecraft] K3 command mode default k30 k31
I beg to differ. The K3 does provide the information on the command state via the 'K2n;' command and the 'K3n;' command. Bull. The K3 does not provide the information in response to the K3n; command. The K3 changes its CAT response - specifically changes the information reported in the IF (auto information) data and its response to several other commands based on the status of K3n; I repeat, any software that needs to issue K31 commands must assure that the K3 is capable of accepting those commands. Router can not arbitrarily place the K3 into K31; mode since it must operate with software that relies on the K30; and certain K2x; behaviors - Ham Radio Deluxe among others. Since Router already relies on the data in the autoinformation packet to determine operating frequency (band) and mode if another application is controlling the K3 it does not poll independently for Mode (MD;) and data sub-mode (DT;). IT IS NOT A MATTER OF NOT CHANGING THE STATE OF THE RADIO - the situation is that the software is trying to issue a command that requires the K31 state. No, the K3# commands alter the state of the K3 command set and CHANGE THE STATE OF THE RADIO. They specifically change the way the K3 interprets certain commands (DS; FW;) and changes the behavior of the b and d bytes in the auto-information report. Full details are in the Programmers Reference Manual. That fact that other radios 'do it differently' is not a reason for software which supposedly supports the K3 command set to make assumptions about the state of the K3. Router does not make assumptions about the state of the radio. It understands fully if the d byte in the autoinformation report is 0 the data submode must either be Data_A or the radio is in K30; mode. Since the K3 does not indicate which is the case, Router treats DATA mode as AFSK/PSK (which is what is being reported) and will not generate FSK from the keyboard or memory since that is inappropriate in the DATA_A submode. To say that Router is at fault because it does not arbitrarily change the K3 CAT mode is hubris. The fact is that the K3 reports DATA A in the autoinformation packet unless the K31; extensions are enabled. That is simply a fact of life just as the fact that Kenwood transceivers and Icom transceivers prior to the Pro series have no way to identify AFSK operation is a fact of life. I do come from a long background that says any software that makes assumptions (without checking) is faulty programming. And I come from a long background that says any control system that does not provide accurate information is a defective control system. However, I don't go around saying the Elecraft implementation of the Kenwood command set is defective even though it clearly indicates that the default data mode is DATA A. In this case, the command set simply does not provide the information necessary for Router to enable its internal FSK keyboard support. That support is also not enabled for the K2 in which RTTY = AFSK. In the case of the K2, Router had to be specifically coded to handle the RTTY mode differently than any other supported transceiver. You simply have no right to declare another company's software (product) defective and I resent it. 73, ...

The K3 does provide the information on the command state via the 'K2n;' command and the 'K3n;' command. The K30 state is clearly documented as the default. I repeat, any software that needs to issue K31 commands must assure that the K3 is capable of accepting those commands. This is a task for the programmer who says they support the K3 command set. IT IS NOT A MATTER OF NOT CHANGING THE STATE OF THE RADIO - the situation is that the software is trying to issue a command that requires the K31 state. The command cannot be received if the radio is not in the K31 state - so either the software must use an alternative method or it must set the K31 state. If the software must restore the radio to the K30 state afterwards (to be good programming) than by all means, issue the K30 command at the end of the process. That fact that other radios 'do it differently' is not a reason for software which supposedly supports the K3 command set to make assumptions about the state of the K3. I do come from a long background that says any software that makes assumptions (without checking) is faulty programming. 73, Don W3FPR Joe Subich, W4TV wrote: Don, That sounds like a programing deficiency in the Microham MK2.

[Elecraft] Audio blast in fw 3.30
Hi Lyle I experienced this audio blast for the first time yesterday evening I try to summarize all the facts: It occurs while switching from 80 to 40m 80m was on CW and 40m was on SSB The S-Meter showed maximum signal, but there wasn?t any strong signal Volume control didn?t seem to function Only solution was to throw away my headphone and then switch off the trx. After switching it on again all was functioning normal I?m using fw 3.30 for some weeks now and even for the latest contests but didn?t experience this audio blast before. S/N is 2702 Is there already a solution in the new upcoming fw? -- /*73 de*/ /*Wolfgang DK9VZ*/ w...@dk9vz.com mailto:w...@dk9vz.com http://dk9vz.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
