[Elecraft] K3: Calibrate RF gain with K3 utility - error messages - help.
Hi all, I'm hoping someone has come across this problem and can help out. I recently got an XG3, so thought I would run the Calibrate RF gain utility in K3 Utility. I'm running the latest K3 firmware and the most recent update of the K3 utility: 1.4.4.25 K3 and computer are communicating fine and Calibrate Tx gain routine in K3 Utility runs fine. Tried to run the Calibrate RF gain routine and I get the following error in the K3 utility window No reponse to DSP command and the calibration progresses no further. On the K3 LCD there is this error message: E 040FA6. ERR DSE I've checked and all the setup parameters for the Calibrate RF gain routine are set correctly according the the on-screen prompts. What am I doing wrong?

[Elecraft] K3 s-meter calibration parameters and flickering S1...
Hello again, Update to my last post: I turned everything off, went and had a cup of coffee, came back and tried the RF gain calibration routine again with K3 Utility - worked just fine this time. So, not sure why those errors. I had turned everything off and re-booted the K3, restarted the utility etc in previous attempts, with no effect. Must've been the cup of coffee :) So now on to another question: After the RF calibration, I re-did the S-meter calibration using the XG3, with the K3 in ABS mode, PRE OFF. SMTR OF = 21, SMTR SC = 14. With these parameters, the scale is very linear and pretty much spot on: S9 @ -73dBm, S2-3 @ -107dBm, S9+40 @ -33dBm BUT, when I disconnect the XG3, so nothing is connected to ANT1, the S1 bar flickers on and off. I can't stop this flickering S1 without readjusting the parameters and throwing out the rest of the calibration. The S1 does turn off if I narrow the bandwidth to less than 1.5khz. I've been doing the calibration in CW mode but with bw set at 2.8khz. Is this flickering S1 with no antenna connected normal/expected? Intuitively, I feel that no input should give no bars, but perhaps that simplistic. 73, John VK7JB -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-s-meter-calibration-parameters-and-flickering-S1-tp6418969p6418969.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 s-meter calibration parameters and flickering S1...
John - I would say that if it is just flickering on and off that is exactly right. It does at least show that the receiver is live and the residual noise is registering on the S-meter. Perhaps if you shorted ANT1 to ground the flickering might reduce. Personally, if my S-meter did not flicker, I would wonder whether my receiver is working ;-) 73 de David G4DMP In a recent message, VK7JB zen...@netspace.net.au writes BUT, when I disconnect the XG3, so nothing is connected to ANT1, the S1 bar flickers on and off.

Re: [Elecraft] K3: Calibrate RF gain with K3 utility - error messages - help.
Just did the same procedure on my K3 (I have the sub-receiver installed in mine) and everything in the RF Gain calibration routine went normally and completed /wrote the value to eeprom for the main RX, but I got the No response to DSP command error when the utility was going through the sub-RX gain calibration procedure. I shut down and restarted everything. I ran through the cal procedures again but ignored the main rx and just did the sub-rx. This time it finished properly for the sub receiver. Leaving well enough alone, I didn't try to repeat the problem. I'm running firmware versions uc 4.36, DSP 1 and 2 2.73 and FL 1.14. The only changes since I got the K3 (back in December of 2010) are firmware upgrades and I had originally had the general coverage bandpass filter installed in the sub receiver only. I have since moved that to the main receiver as I found it was more convenient in that position due to the way I like my audio configured.

Dave, Do a Google search for Coby CA-745, an FM wireless transmitter that plugs into a cigarette lighter. You can find them at Amazon, Wal-Mart and Best Buy for between $16 and $19. The input is via a stereo miniplug at the end of an attached cable. The frequency can be changed and is displayed on an LCD screen on the front of the unit.

[Elecraft] Still lacking
As a portable user of the K2 and Vertex 1210, I was thrilled to hear about the new KX3. After reading the preliminary specs however, I think I´ll stick to my existing radios. Why? - 10 W is insufficient power for portable SSB operation on the lower bands, at least in Europe. 20-25 W as the 1210 has is still low, but acceptable in terms of balancing power with current consumption. - My old 1210 has built in Lithium batteries which are light, high capacity and fast charging. Why not in the KX3??

[Elecraft] Some Speaker Options
Hi Folks, I've been trying out a couple external speaker ideas for some various Elecraft products; both ideas save some desk space and so might be considered where space is at a premium. One uses the Dell soundbar AX-510. This unit mounts to the bottom of most recent Dell computer monitors; many of these monitors have a jack for soundbar power, or a wallwart-type supply can be used. These speakers have an integrated 5 watt amplifier with volume control on the side, and can be used in conjunction with the computer sound card, or just used with external audio input (line out from the K3 for example). The second soundbar option uses a Sharp CP-USB50, which is a USB-type speaker, so this would need to be used by running Elecraft audio into the computer and listening via the soundcard. Only a USB connection for the soundbar is needed. The Sharp unit fits and looks very nice on top of the K3. The Dell option might be a good choice for something like the KX1.

Re: [Elecraft] K3: ammeter display does not include 12 RCA acc skt?
Hi Stephen, The aux 12 V output is not part of the current-monitored path. The main reason for the current monitor is to keep track of the health of the radio itself, so we take corrective or informative action in either RX or TX mode. 73, Wayne N6KR On May 30, 2011, at 10:18 AM, Stephen Prior wrote: Well, it's in the title really, but I was surprised to find that turning the P3 off does not reduce the current reading on the K3 display (the P3 is powered by the 12v acc skt).

Check the schematic. The aux 12V is really close to the 12V input, being dropped by one diode and a FET junction. There's no shunt in that leg.

Re: [Elecraft] Still lacking
Hi Terje, The KX3 is a completely different radio from the Vertex 1210. It is much smaller, lighter, and has far less current drain. It can even be used hand-held. There's simply no room for a 20-W PA and/or a large battery. The 1210 is a channelized man pack radio, which definitely has its advantages for certain operating situations. However, the 1210 is about 4 times larger than the KX3 by volume, and about 5 times heavier. It draws about 3 times as much current when receive is active (it draws less in Saver mode, but this is with the receiver squelched, periodically looking for channel activity). Despite the KX3's much smaller size/weight/current drain, it has several major advantages over the 1210 as a general-purpose ham transceiver: 6 meter coverage (and possibly 2 m, 4 m, or other bands), FM and data modes, large display, large VFO knob, controls for many more functions, optional attached keyer paddle, and optional narrow roofing filters for high dynamic range. Of course there's also the external 100-W PA. The KX3's current drain is low enough that it can function well with an extremely light battery pack (8 AA cells, internally, or your choice of external batteries). We went with AA cells because of their flexibility and ubiquity. You can always borrow some from other electronic devices in a pinch. You can power the radio for 5-10 hours of typical transceive operation or 16 hours receive-only from a set of nonrechargeable lithium camera batteries. Or you can use NiMH, with the internal charger keeping them ready to go. So it's really an apples/oranges comparison, in my heavily-biased opinion :) 73, Wayne N6KR As a portable user of the K2 and Vertex 1210, I was thrilled to hear about the new KX3.

Re: [Elecraft] Still lacking
Ok, you win, I´ll order a KX3 when it arrives! I have quite a few 5-10w portable radios gathering dust unless I plan to operate CW. My trusty K2 has the 100W PA, which I usually run at 25-50 watts using a 14AH battery and an K1 tuner (which tackles 50W well in spite of being rated lower). The power difference is not impressive in terms of db, but when operating SSB on 60m and below having a bit more power output often is the difference between having a QSO and having a frustrated operator at both ends. Please consider a KX3 Heavy Duty version, with a lithium battery and higher power output (25W) in a bigger box. There really is gaping hole in the market for such a rig, since most rigs either are too puny in terms of power or battery capacity (i.e. FT-817) or too battery thirsty (FT-897 for example). I would buy one or two on the spot, and I know a lot of hams who for various reasons have to operate portable - typically having residential noise problems or antenna restrictions - likely will buy one as well. 73´s Terje Den 30. mai 2011 kl. 19.47 skrev wayne burdick [via Elecraft]: Hi Terje, The KX3 is a completely different radio from the Vertex 1210. It is much smaller, lighter, and has far less current drain. It can even be used hand-held. There's simply no room for a 20-W PA and/or a large battery. The 1210 is a channelized man pack radio, which definitely has its advantages for certain operating situations. However, the 1210 is about 4 times larger than the KX3 by volume, and about 5 times heavier. It draws about 3 times as much current when receive is active (it draws less in Saver mode, but this is with the receiver squelched, periodically looking for channel activity). Despite the KX3's much smaller size/weight/current drain, it has several major advantages over the 1210 as a general-purpose ham transceiver: 6 meter coverage (and possibly 2 m, 4 m, or other bands), FM and data modes, large display, large VFO knob, controls for many more functions, optional attached keyer paddle, and optional narrow roofing filters for high dynamic range. Of course there's also the external 100-W PA. The KX3's current drain is low enough that it can function well with an extremely light battery pack (8 AA cells, internally, or your choice of external batteries). We went with AA cells because of their flexibility and ubiquity. You can always borrow some from other electronic devices in a pinch. You can power the radio for 5-10 hours of typical transceive operation or 16 hours receive-only from a set of nonrechargeable lithium camera batteries. Or you can use NiMH, with the internal charger keeping them ready to go.

[Elecraft] K3 unusual noise
Hello My factory built K3 is about six weeks old and today it started doing something that I have never had a rig do before in 40 years of hamming. I was listening on 20 meters CW and the K3 suddenly started making a fast ticking noise at various speeds. The wind was blowing about 40 miles an hour and I suspected that. So I disconnected the antenna. The ticking noise continued. So then I turned the K3 off, and even with the rig turned off and the antenna disconnected, the ticking coninued for several minutes. The ticking was about as loud as one normally has the audio set when in use. Since the rig was new I have had a one megohm resister across from the center conductor of the coaxial cable to the braid on the coxial cable. After letting the rig set turned off for a few minutes, I turn it back on and everything seems normal. Anyone have any ideas about what might be going on?

There is potential for significant difficulty using a device powered from one point in the automotive DC power with another device powered from a DIFFERENT point in the same automotive power system. The reason is simple -- there can be a lot of DC resistance between different parts of the system, and a lot of noise, both audio and RF, between those points. The audio interconnect is unbalanced, so any noise that is present is likely be added to the audio feed. Consider the use for which these modulators were designed -- a BATTERY-powered personal music player, like an iPod or CD player. With these devices, there is only ONE connection to the automotive power system, the lighter plug. Ditto with a wired AUX plug-in for those players.

Re: [Elecraft] KX3 current
Hi Igor, The 150 mA target is with the backlight off. It's a transflective display, so it's highly visible even with no backlight, except at night. But we'll have a low setting of the backlight that adds very little current drain -- maybe 10 mA. The LCD itself, and its controller, draw almost no power, so turning the display completely off wouldn't buy anything. However, we'll be looking at various ways to cut current drain and will explain them in the owner's manual, as we did for the K2. 73, Wayne N6KR On May 30, 2011, at 2:39 PM, Igor Kosvin wrote: Wayne, Is the 150mA RX current of KX3 is with the LCD display on and some level backlight active?

Re: [Elecraft] Weak Signal Propagation Reporter WSPR software (need help with it)
Hi Stan, You can do it. I'm probably older than you (72) -- it just takes patience and some fiddling. The first thing to do is to plug in those patch cords. In fact, let's start with just one. Plug it into the Lin Out on the back of the K3, and the Mic jack on your computer. Then bring up WSPR. Set the Transmit % slider to 0% so that it won't try to transmit. Then click the Setup menu at the top, and open Station Parameters. Put in your call and your grid square (you can find it out on QRZ.com if you don't know it. Look up your call, then click details). Then click the drop-down menu for Audio In and select Microphone. Make sure your computer's clock is accurate to within 1 second. There are various ways to do this, but for the moment I'll assume you have that figured out. Set your receiver on 14095.6, USB, and on WSPR select Band20M. Now make sure the Idle box is not clicked, and wait for the beginning of an even-numbered minute. Pretty soon you'll see a green box at lower right saying Receiving, and the lower left box will say Rx Noise XX DB. On the K3, adjust Config Line Out to bring the Rx noise to somewhere near 0 DB. To fine-tune the audio in, look on the Task Bar for the little picture of the speaker (lower right, next to the time date). Right-click that icon, and a menu will appear. Select Recording Devices. A menu will pop up. Double-click Microphone, and then select the Levels tab. A slider will appear, which you can adjust to get the Rx Noise to (more or less) 0 DB. Now go get some coffee and let WSPR run in receive mode for a while. If your system clock is accurate, you'll see callsigns appear in the white box. You're receiving!! Once you get to that point, email me and we'll try to get you transmitting. Good luck 73, Tony KT0NY __ 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] Thermal Stress in K2, K3 and I guess KX3
Hi John, I have a 100W K3 here and my shack is an un air conditioned 20Ft container in tropical north Queensland, Australia. Needless to say, it does tend to get a trifle 'warm' in the wet (summer) season here, with outside temps in the mid to high 30's (Celcius). Internal temps in the container can be as high as 60 degrees with all the windows / doors cloased up. (The radio is not generally operating when temps are that high) I have only ever twice had my K3 shutdown due to over temp, in both cases the shack temp was well over 40 degrees C.. (And closer to 50!) The first time was the internal 2M module shutting down, the second was the main VCO. The K144XV shutdown was cured by updating the firmware to the then latest version, (1.02 I think it was at the time) which increased the shutdown temperature and the second was apparently cured by recalibrating the main VCO. Neither issue has ever come back to haunt me and my K3 does get subjected to some extremely high temperatures due to my living and being portable in the tropics. Never once has my K3 drifted in frequency to any noticable extent though I do have the TCXO option. (In fact, my K3 #4257 is almost fully optioned, it is only missing the second receiver and its associated filters.) In both shutdown cases, my FP temp was over 60 degrees C as indicated by the radios display. 73 de Jeff Cochrane - VK4BOF Innisfail, QLD, Australia Elecraft K3 #4257 + KPA500 + PR6 + K144XV = Multiband greatness! - Original Message - From: John To: elecraft@mailman.qth.net Sent: Tuesday, May 31, 2011 8:10 AM Subject: [Elecraft] Thermal Stress in K2, K3 and I guess KX3 All, Has anyone seen any degradation or temporary non-operation in the QRP versions of the K2 or K3 while operating in hot conditions?

I'll get back to playing with my K3. 73, John VK7JB -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-s-meter-calibration-parameters-and-flickering-S1-tp6418969p6420986.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] WSPR
Extremely easy to set up, just two audio cable plus the serial port. I have had reports using 100mW at over 200,000 Km per watt and using simple wire delta loop antenna. I have copied station from the UK who was using a small copper loop antenna, about 4 feet diameter. I am also active on JT65hf and getting very good results. The K3 must be the simplest rig to set up for digital modes. Be prepared for frustration though. You will hear much more than you can work!! 73 Max/ZL4VV __ 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] WSPR
It actually works fairly good. You dont get confirmed contacts per say, but you can see your propagation information via a map on the web. Its actaully fairly amazing how far 0.5 watts can go. I also now know what another signal looks like on the DM780 trace. I played with it today and its another tool in the toolbox to see what my antenna is capable of doing.

Re: [Elecraft] WSPR
I find the JT65 very frustrating to get a qso in, as I can hear them but they don't seem to hear me.. But then that is what patience is for with only 15 watts being used.

Re: [Elecraft] WSPR
It's even more amazing how far 0.5 watts can be heard and information exchanged using human brains as the encoder/decoder software. You can tell how far a few watts, even 100 mW (0.1 W) can be heard by simply tuning in the NCDXF/IARU beacons on 20 through 10 meters - no computer, no special software, just your receiver and your ears needed: http://www.ncdxf.org/beacon/beaconschedule.html Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of gold...@charter.net Sent: Monday, May 30, 2011 7:02 PM To: Wes Stewart Cc: elecraft@mailman.qth.net; Max Kempson Subject: Re: [Elecraft] WSPR It actually works fairly good.
