Re: [Elecraft] P3 ?
I'm curious if anyone from Elecraft can provide rough price estimates? Sub 500? Sub 4 digits? Sub 1.5Kilobucks? Can you at least provide pricing to this resolution? ~Brett (KC7OTG) On Wed, 2009-08-12 at 02:50 +, Brian Alsop wrote: Bob, Given that the K3 display is 1x5, this display would be 4x as large. That doesn't seem too small to me. I'm a bit surprized by the size-- particularly the depth. I was hoping for something I could put anywhere. The depth and 6 width strikes me as somewhat excessive for my needs. Desk real estate is always limited. It seems like every piece of equipment has to be at eye level and within easy reach while sitting down. Hard to do. 73 de Brian/K3KO Bob Cunnings wrote: One thing to consider - According to the P3 announcement: It's the same height and depth as the K3, and about 6 wide... Which implies, if I'm interpreting this correctly, a max display size of less than 4 x 6. Using LP-PAN and latest PowerSDR I can have a much bigger spectrum display on my 21 monitor. The panafall display is absolutely gorgeous when maximized, and resolution is excellent. The announcement was silent on the size and resolution of the P3 display panel. The LP-PAN/PowerSDR system may offer a substantial advantage in that area.

[Elecraft] QSK
...input from the Elecraft community about a new amplifier... ...Acom 1010 but I can not determine... that amplifier really has QSK. ...I love QSK... Jim: My $.02 worth - I have an Acom 1000 - absolutely full true QSK. It takes advantage of the Ft-1000mp QSK feature - the 'ready to xmit' signal is fed from the radio to the amp. The amp closes it's relays and returns an 'OK' signal to the radio. The radio then produces the neccessary RF. At the conclusion of the character, the proceedure is reversed. The amp is NEVER hot-switched. All this from the closure of the key in less than the blink of an eye, and in complete silence - a marvel to behold. It produces +/- 1000 watts out, 160 to 6m. The Acom 1010 is a lower powered version - lighter for DXpeditions, 600w out but no 6m coverage. Same GU74b tetrode. Not to say that there aren't other good amps out there.

Re: [Elecraft] P3 and options
Putting a loudspeaker in a unit that sits at the side is in my view a retrograde step. I dare to suggest that most of us have reduced hearing in some way and a loudspeaker should best be placed in line with our ears eg a light weight speaker on a shelf at ear height. I would not stand such a unit on top of the K3, either. I like the mains power as far from the antenna as possible and some would like to keep the bench free of mains supply, everything being powered from 13.8V under the bench, we do that at the club for general use. I like the idea of a monitoring scope David G3UNA If the P3 band-scope were set up to occupy one-half of the width of a cabinet that was otherwise the same size as the K3, then perhaps a future gift from Aptos could come in the form of a transmit monitor scope (to monitor a the CW/SSB/AM modulation envelope) that would fill the other half of the enclosure.One of the best options back in the old Heathkit days was to have both the HO-10 and the H0-13 (or their SB series big brothers) sitting side by side. Looked great, and gave useful information to the operator in the form of assurances that the outgoing signal was clean.The monitor scope function could also operate during receive so a person could check the other guy's signal for flat-topping, under and over modulation, etc. Other options for the unused half of the P3 cabinet could include a speaker, a rotor-control / indicator for some of the more popular units, and, as someone already suggested, a small 20 to 30 A switcher that could provide power for the K3 and perhaps a few accessories. Lots of possibilities here. - Jim, KL7CC __ 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] QSK options inquiry
I recall sometime ago enquiring of Ron Stone GW3YDX at Vine (UK Acom sales) and being told that the 1010 doesn't have vacuum relays and to go with the 1000 if I was serious about QSK.

[Elecraft] P3 Preferences
Great news on the upcoming panadaptor. I'd definitely be interested (especially if the exchange rate moves in the right direction in the meantime!)

Re: [Elecraft] QSK options inquiry
Doug, Here's what I've gleaned on the 1010 The 1010 is a different beastie from the 1000. It isn't just a 1000 without 6M. 1) takes more drive for full output. 2) full output at least a few hundred watts less. (I also believe the transformer is not has hefty) 3) an electronicly controlled bias circuit 4) The RF deck is different, it doesn't have the extra shielding the 1000 has. This is both a plus (if you change tubes) and a potential negative. It is a good amp for countries with an enforced 400 W power limit. Unfortunately I can't comment on the amp key circuit or QSK. 73 de Brian/K3KO Jim Danehy wrote: Doug Same problem here finding out anything about sales in North America.

[Elecraft] SWR-Meter acurracy?
Elecrafters, please comment on this. Is there a way to calibrate the SWR-Meter? I have a K3 w/o internal Tuner. With a Dummy connected, the SWR readout never is better than 1.1 : 1. Not that this makes any difference but i have seen a readout of 1.0 : 1 on a second K3, also w/o internal tuner. With an external SWR meter connected, while matching my dipole with my homemade tuner, the K3 shows 1.1:1 long before the needle on the external swr-meter settles. In other words, the internal Meter shows good swr, the external meter shows that it is possible to set it even a little better. I ask for your input on this because i run a tube amp and Tuner. The lowest swr possible helps the tuner amp to stay cool -and the owner. The external Meter is hooked between the K3 and the amp.

Thanks for all the replies. All is well in K3 land here! After loading the unit software and usb driver on my laptop and running the util from there, the K3 reloaded the firmware. All I had to do then was get the com port back to speed for the software I use. Forgot the K3 had an rs232 speed setting in it. daaah!! Now it's working.

[Elecraft] new to a K2 hesitation on power out TX in general
I just bought a used pre-built K2 from a local friend. I bought the rig for my main QRP station in the house and also to take out where ever I decide to operate radio. I very much hope it is durable enough to travel in a bag. I'm still trying to get used to this rig. It was a huge investment toward my hobby and I am still a little nervous it isn't functioning quite right or won't meet my needs. I notice a hesitation in output power when I first key the rig after changing bands. IS THIS NORMAL DUE TO THE BAND SWITCHING RELAYS? It is a little annoying when trying to call that first station on a new band and they miss the first letter of my call and have to ask for it again. After the intitial key down it seems to work fine. I also have more output power at least on 20 and 40 meters than what the power setting is set to. last night with the output power set to 5 watts I was getting about 7.5 watts out. I plan to change out the resistor in R98 to correct this problem. I would also like to know what ideas any of you have come up with to reasonably weather proof the radio while using it outside. I only have the noise blanker and SSB board in it right now so there seems like a lot of holes in the back for dirt or a critter to crawel into and there are a lot of seams around the panels. The reflector has helped answer some questions and of course is a great resourse. Thanks!

Re: [Elecraft] P3 and options
No speaker in the P3 right now. We'd want it to be front mounted and that would make the P3 width too large. 73, Eric WA6HHQ David Cutter wrote: Putting a loudspeaker in a unit that sits at the side is in my view a retrograde step. I dare to suggest that most of us have reduced hearing in some way and a loudspeaker should best be placed in line with our ears eg a light weight speaker on a shelf at ear height. I would not stand such a unit on top of the K3, either. I like the mains power as far from the antenna as possible and some would like to keep the bench free of mains supply, everything being powered from 13.8V under the bench, we do that at the club for general use. I like the idea of a monitoring scope David G3UNA If the P3 band-scope were set up to occupy one-half of the width of a cabinet that was otherwise the same size as the K3, then perhaps a future gift from Aptos could come in the form of a transmit monitor scope (to monitor a the CW/SSB/AM modulation envelope) that would fill the other half of the enclosure.One of the best options back in the old Heathkit days was to have both the HO-10 and the H0-13 (or their SB series big brothers) sitting side by side. Looked great, and gave useful information to the operator in the form of assurances that the outgoing signal was clean.The monitor scope function could also operate during receive so a person could check the other guy's signal for flat-topping, under and over modulation, etc. Other options for the unused half of the P3 cabinet could include a speaker, a rotor-control / indicator for some of the more popular units, and, as someone already suggested, a small 20 to 30 A switcher that could provide power for the K3 and perhaps a few accessories.

Re: [Elecraft] P3 ?
We see the P3 and LP-PAN as complimentary products with their own unique featuress. To be honest, I can run both at the same time on my K3 :-) LP-PAN and a high power PC certainly offers a wide range of processing and display options at the cost of a more complex PC/LP-PAN/sound Card box set up and cost. I do not see it going away as a popular option for the K3. The P3 is a powerful and compact, tightly integrated, panadapter display for the K3 that does not require a PC to be configured for its operation. This makes it ideal for both desktop and portable operation. Its plug and play with no s/w issues surrounding the K3/P3 usage with other external control programs like logging and contest programs. Its fully transparent and fast to hook up. It has the ability to do -both- spectral and waterfall displays, including a split screen mode with both. On screen cursors can be moved to desired signals and then clicked to center the K3 on that frequency. More pics and info after we get back from the Santa Barbara show next week. 73, Eric WA6HHQ --- __ 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

Stewart: Whatever option you decide upon, you will find the panadapter to be a great device for localizing and killing various forms of EMI interference. For me it's become almost an obsession to find a blip on the screen then start throwing circuit breakers in an attempt to find the noise source. Since the time of owning the SDR-IQ unit, I have replaced power supplies on my daughter's Sony Playstation, two wireless routers, an UPS for my home office, several USB-to-Serial adapters and the noise floor is now reasonably clean. So beware, if you're concerned about EMI spectrum pollution, the addition of a pan adapter is so useful that it may keep you busy for a while -- although the exercise to/from the breaker panel will be good for you.

Re: [Elecraft] P3 ?
Dear Larry, Big question: QUADRATURE OUTPUTS?? It seems to me that if Elecraft does provide quadrature outputs from the P3, then, besides being a stand alone panadapter, the P3 might also effectively replace the LP_PAN unit . You could just plug those quadrature outputs into your sound card and then use PowerSDR-IF stage and LP_Bridge on your computer just as if you had an LP_PAN. Why do that? If you just want a panadapter, then there is no reason to. But if you want to use other features of PowerSDR like an alternate set of DSP implementations, maybe better audio, maybe more resolution on the screen, etc., then you can use those quadrature outputs with your computer and Power SDR to get that. You'll effectively have a FlexRadio receiver on your desktop (K3 front end, PowerSDR back end) along with your K3 and its panadapter. One benefit of the P3 is likely to be important only to people who have problems with RF in the shack. The LP_PAN setup can be a rat's nest of cables and adapters. It is very vulnerable to RF, and hard to get clean. The P3, however, is all in one metal box, and is presumably tested by Elecraft to play well with the K3 when connected. This could be an important benefit. Of course, you might lose that benefit if you then connect things to the quadrature outputs. :-) Hope this is some food for thought. 73, Oliver Johns W6ODJ On 11 Aug 2009, at 5:20 PM, telegrap...@att.net wrote: Now i guess what i have to ask is how will this affect up with the LP Pan program and adapter?

[Elecraft] [K3] PC Noise
G'day, Continuing my investigation into PC noise I tried for the first time using the CAT interface of my microHAM CW Keyer. Basically this provides a USB to RS232 conversion CAT interface and a WinKey. For more info on the other twiddly bits see the microHAM web site. K3 on 6 metres, PR6 on, PRE OFF and the antenna port terminated with 50 ohm load. No noise. Quieter than the CAT6 based RS232 cable I use because with the cable I can just hear PC noise as I task switch and the CRT monitor updates. Previous measurements showed the directly connected KUSB to be approximately +10dB noisier than the RS232 cable. No connection with microHAM other than buying a CW Keyer a couple of years ago.

[Elecraft] K3 FIRMWARE, Rev. 3.25: Improved NR, 10-Hz SHIFT steps, Received CW WPM display, VFO noise reduction, etc.
K3 beta-test firmware revision 3.25 (with DSP rev. 2.21) is now available. There are several new features and significant improvements in this revision; see release notes below. Please send problem reports to k3supp...@elecraft.com. Beta firmware load instructions can be found at http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 3.25 / DSP 2.21, 8-11-2009 New Features: * NOISE REDUCTION (NR) IMPROVEMENTS: Our new NR algorithm has less impact on signal strength, and should no longer make some weak signals “disappear” due to over-processing. We may fine-tune the algorithm in future releases, based on operator evaluation, but we’ve have good reports from early testers. * VFO TUNING NOISE REDUCTION: Some operators have reported hearing noise on 60, 10, or 6 meters when tuning the VFO under very quiet conditions. If you experience this, try the following: In the CONFIG:VCO MD menu entry, tap ‘1’ until you see “SPI 2” (the default is “SPI 1”). This alters the timing of data sent to the synthesizer, which in turn changes the spectrum of SPI-bus signal noise. It has no impact on performance. You will also need to add two resistors and two diodes to the bottom of the RF board (see application note on our K3 modifications web page). * AUTOMATIC RECEIVER FRONT END PROTECTION: If the K3 is operated too close to high-power transmitters, it’s possible to damage some receiver components. While this rarely happens, we’ve taken steps to prevent it by sensing a high-current condition at the mixer post-amplifier (Q8/Q9) and automatically turning off the preamp and, if necessary, turning on the attenuator. You will need to add one jumper wire on the bottom of the RF board (see application note on our K3 modifications web page). If you don’t add the jumper, operation will be unchanged; firmware can sense whether or not you’ve installed the jumper. * 10-HZ PASSBAND SHIFT STEPS (EXPERIMENTAL): If CONFIG:PB CTRL is set to SHIFT=.01 for a given operating mode, the SHIFT control will provide .01 kHz (10 Hz) steps rather than the original .05 kHz (50 Hz). Especially useful with narrow filter bandwidths. This feature is experimental and has some limitations at present: Applies to CW and DATA only; LOCUT/HICUT cannot be used when 10-Hz SHIFT steps are in effect; WIDTH steps remain 50 Hz in all cases. Not compatible with spur removal function yet (CONFIG: SIG RMV); signals mapped out may reappear. * CW SPEED DISPLAYED WITH DECODED CW TEXT: If the TEXT DEC switch parameter is set to WPM CHK (using VFO B), the speed of on-air CW signals will be shown, along with a small window of CW text. You might see “18w. CQ…”, where “18w.” means 18 WPM. Both text decode and WPM display accuracy can be improved by using narrow filtering and by careful adjustment of the “THR” (threshold) parameter (set with VFO A when the TEXT DEC switch is pressed). * RF GAIN CALIBRATION: The K3’s hardware AGC circuitry can now be calibrated. This may improve both S-meter and RF GAIN control accuracy. To do RF GAIN calibration, use revision 1.2.7.24 or later of K3 Utility (use the RF GAIN calibration function, under Configuration). This procedure calibrates both main and sub receivers. A signal source is required. Future firmware revisions will further improve accuracy, using the calibration data stored by this procedure. Misc. Improvements: * SK IS NO LONGER DISPLAYED IN RESPONSE TO NOISE DURING CW DECODE. Incorrect characters are now displayed as ‘*’. * 6 METER SCANNING NO LONGER PROHIBITED. Scanning is limited to the 6-m U.S. ham band (50-54). Exception: In some countries the K3 won’t operate on 6 m at all. * TTY CENTER FREQ NOW DISPLAYED CORRECTLY: In FSK-D and AFSK-A modes, rotating SHIFT now shows the exact center pitch (when indicated by an asterisk). The four available center pitches are 1000, 1360, 1530, and 2210 Hz. Previously the pitch was rounded down to the nearest 50 Hz. For Software Developers: * RO COMMAND (RIT/XIT OFFSET READ/SET) ADDED. This command provides a more direct way to set up the RIT/XIT offset, as an alternative to “RU” and “RD”. Set/Response format: ROs; where s is +/-, and is -. --- http://www.elecraft.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] qsk options inquiry
I have the Acom 1000 and use it with the K3/100 (#250)...full QSK, no problems at all with keying,(up to 44wpm) etc. I got it in 2004. I have made over 15000 Qs with many of these Qs during contest operations, phone, cw and rtty. I do crank it back to 500w out when running rtty so as to run a little cooler. If you like computer controlled amps, this is a remarkable little amp, very quiet and puts out about 600w or so. It is NOT a 1000w amp...the specs on the tube the 4CX800 say plate dissipation is 800w...plug in typical efficiency and that will put it down around 600wto 680wMy LP-100 shows 800w peak and my Bird shows around 600-650w (key dwn) output into Steppir 3 ele yagi. Not sure that anyone could tell the difference over the air if power was 1000w or 600w. Not sure about the marketing of the amp now...did Array Solutions or DX Eng pick up the line in the US?

Re: [Elecraft] P3 ?
Nice post, Oliver. All of what you say is exactly why I've been anxiously waiting for the P3, and why I won't even consider buying one if it doesn't have buffered I/Q outputs. Aside from existing software like PowerSDR and CW Skimmer, think of all the other future possibilities for third party SDR-type applications ... automated band monitoring, intelligent band scanning, contest activity statistics, propagation studies (for example, transmit two signals 5 KHz apart, one with vertical polarization and one with horizontal polarization, and let the SDR software on the other end track both simultaneously), etc. There is simply too much potential from having access to quadrature data to go without. I find it almost unimaginable that Elecraft would introduce the P3 without that capability since (at least from my perspective) it would be easy and inexpensive to do it, but sadly that appears to be the situation thus far. 73, Dave AB7E --Original Mail-- From: O.

It seems to me that if Elecraft does provide quadrature outputs from the P3, then, besides being a stand alone panadapter, the P3 might also effectively replace the LP_PAN unit . You could just plug those quadrature outputs into your sound card and then use PowerSDR-IF stage and LP_Bridge on your computer just as if you had an LP_PAN. Why do that? If you just want a panadapter, then there is no reason to. But if you want to use other features of PowerSDR like an alternate set of DSP implementations, maybe better audio, maybe more resolution on the screen, etc., then you can use those quadrature outputs with your computer and Power SDR to get that. You'll effectively have a FlexRadio receiver on your desktop (K3 front end, PowerSDR back end) along with your K3 and its panadapter. One benefit of the P3 is likely to be important only to people who have problems with RF in the shack. The LP_PAN setup can be a rat's nest of cables and adapters. It is very vulnerable to RF, and hard to get clean. The P3, however, is all in one metal box, and is presumably tested by Elecraft to play well with the K3 when connected. This could be an important benefit. Of course, you might lose that benefit if you then connect things to the quadrature outputs. :-) Hope this is some food for thought. 73, Oliver Johns W6ODJ On 11 Aug 2009, at 5:20 PM, telegrap...@att.net wrote: Now i guess what i have to ask is how will this affect up with the LP Pan program and adapter?

[Elecraft] Off Topic - 2009 Kyrgyzstan 50 MHz DXpedition from Grid Locator MN82re starts SUNDAY!!
Just a final reminder to any K3 owner with a 6m yagi and an amplifier - some REAL MAGIC is just about to begin ;-) The EX7MW/EX8MLT 6m DXpedition starts with their moonrise on Sunday! That corresponds to moonset in the USA and is around the middle of the day. They should be able to complete a JT65A mode contact with anyone having good ground gain and a 5 element yagi and 500w. CNDX for 6m EME next week look excellent, and they steadily improve as the week progresses. Mike and Oleg have specially selected a quiet location with excellent ground gain over the large lake Issyk-Kul. They will be elevating their antenna when the moon is higher than 20 degrees, so they can continue to operate during your moonrise or moonset. Don't miss out on this great opportunity to contact a rare DXCC on 6m! The K3 makes it simple to operate digital modes! If you still have not tried JT65A mode yet, there are tips on how to use it for EME on my website: http://www.bigskyspaces.com/w7gj/JT65.txt Remember that they will always transmit in the first sequence, so you always leave the TX FIRST box on your JT65A screen UNchecked. Watch for more updates and info at: http://6meme.ex7mw.com/ http://www.mmmonvhf.de/latest.php If you copy them please call them!! Just remember to spread out with 200Hz between callers!

Re: [Elecraft] K3 sudden power loss
Welcome to the club. My K3 has done that twice. It is currently in Aptos for repair of this problem...again. Philip Gary Hinson wrote: Hi all. Yesterday afternoon my K3 #2887 was merrily transmitting 33% at 5W on 17m for WSPRnet as normal when by chance I noticed the external wattmeter was showing no power out on transmit - none at all, not a squeak. The internal wattmeter is also showing no power out, aside from the first bar permanently lit in TX. The receivers still seem to be working fine. The rig was working OK up to then and has been since mid-April. I wasn't fiddling with any of the settings at the point it packed up, but before anyone asks here are the ten checks I've done so far: 1. I tried sending CW and SSB - neither works. Nor does TUNE, at any power setting. Nor does any other band. 2. I tried using VOX on both semi and full break-in, and PTT - no joy there either. The TX LED lights as expected but no watts escape. 3. I've plugged a 100W dummy load directly into the ANT2 socket, selected ANT2 and tried transmitting, just in case there's some cable or antenna problem. Nope, that's not it. 4. The K3 is not in TEST mode (the TX light is on continous not flashing). I cycled TEST mode on and back off to be real sure. 5. I checked CONFIG: TX INH is off, and again cycled it through the other settings to be sure to be sure. Nope, not that. 6. I tried running the TX gain configuration through K3 Utility: the front panel shows ERR TXG and the K3 Utility reports: Unexpected response DS@@°À; to DS; State 153 Calibration power settled at 0.0 W .; There be gremlins. 7. According to the internal metering, the K3's voltage is reading a steady 13.5V and the current sits at about 1.28A on RX, increasing to about 1.62A when I hit the PTT. No change from that level when I key the paddle or speak into the mike, whether whispering, shouting or swearing. I even tried coaxing it to life, complementing it on the colour of its LCD ... 8. The power setting makes no difference: I've tried from 0 to 100W. I hear the PA relay engage around 12W as normal, and the internal power meter changes between high and low settings as expected. It's just taunting me. 9. The 20A circuit breaker on the PA is in - not that I'd have thought it would prevent the QRP level working at least. 10. I've reloaded *all* the firmware: I was using the latest beta 3.25. Reloaded that, no change. Reloaded an older version 2.78, still no change. What should I try next? I guess I need to pop the lid, look for smoke emitters and poke around at the TX driver and PA stages plus the antenna change over relay and ATU area with a multimeter but haven’t figured out exactly where to poke yet, nor what I should expect to see on the meter when I do ... I have other radios here and a scope. I guess I could try to trace the TX signal with the K3 set to QRP, fishing around with a wire tail on another radio's antenna socket or the scope input ...

Re: [Elecraft] K3 utility and calibrate RF gain
Hi, I have just installed this and run the Calibrate RF gain and I am impressed with the improvement. My S-meter was accurate at S3 and S9 but grossly exaggerated beyond S9+10. After calibration it remains accurate at S3 and S9 (needed no further S meter calibration) and now is much better at high signal levels. Unfortunately my modified XG1 (normal XG1 + 40dB) had been left on and run down the battery so I have only been able to test the higher levels by comparing K3 and LP-Pan/PowerSDR readings on strong 40m AM stations, but they are quite close. This also much improves the S-meter when backing off on the RF gain. Very useful improvent and the first one in months that prompted me to upgrade.

Re: [Elecraft] k3 - SWR-Meter acurracy?
Hi Martin, This topic passed through the group a couple of weeks ago. Don has some very good comments on it. I can make a few *un-official** comments based on my own limited experience. I am a K2 owner rather than a K3 owner, however, I have a hunch the SWR circuits are close approximations. The K2's SWR circuit has the typical line passing through the center of a toroid with a couple of trim-caps and diode FWD/REF rectification. What is tapped off this are FWD REF voltages. The typical SWR circuit in an external tuner is almost identical, except that the FWD REF energy is tapped off as a current which is then series_R limited (trim-pot) for driving an analog meter. The (trim-pot), in all probability was tweaked to adjust the analog meter reading with 100 watts applied. Long story short... I use an outdoors mounted auto-tuner, and I wanted to watch it adjust SWR when I switch frequencies. So I built myself a tiny analog SWR meter using one of the MFJ meters and a modified rectifier circuit. I wanted to test its readings up the scale to 100 watts. Don reminded me of the voltage reading that can be taken on a dummy load (non-reactive resistance) with an HF probe and a scope. IF you have a scope, give it a try. Just tap across the dummy. Set the probe to 10X so there is no circuit loading. wattage = (mV reading * mV reading)/400 This assumes an R of 50 ohms.

Also when changing the shift settings, the radio goes to a narrower filter automatically as the change takes place. I guess that is how it is supposed to be.

Re: [Elecraft] [K3] Nice NR improvement with Beta 3.25
Agreed. After about 6 minutes of exhaustive testing (hi!) I can hear a noticeable difference. I still get some volume drop when NR is switched in, but when I increase AF Gain to compensate the noise level remains low. Well done! Paul WW2PT NZ0T wrote: I just downloaded the new utility and Beta 3.25. The DSP NR is much better in terms of not reducing the volume as much. I have never been a fan of NR because it always (on all rigs that have it not just the K3) sounded to me that the volume was reduced so much that by the time I turned the AF gain up enough to produce the same level the noise was just as bad to my lousy ears. -- View this message in context: http://n2.nabble.com/Nice-NR-improvement-with-Beta-3.25-tp3434522p3434996.html Sent from the [K3] 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 FIRMWARE, Rev. 3.25: Improved NR, 10-Hz SHIFT steps, Received CW WPM display, VFO noise reduction, etc.
This is a welcome update for all K3 owners. I just wanted to thank everyone at Elecraft for listening to your customers and implementing these needed features and fixes. A special thanks to Lyle for being patient, and listening to all of our suggestions and criticisms. Also a big thank you to Wayne for remembering our VFO noise plight; I doubt you would remember our conversation over the phone several months ago, but I'm glad you did not forget this issue. 73 de James K2QI On Wed, Aug 12, 2009 at 3:49 PM, wayne burdick n...@elecraft.com wrote: K3 beta-test firmware revision 3.25 (with DSP rev. 2.21) is now available. There are several new features and significant improvements in this revision; see release notes below. Please send problem reports to k3supp...@elecraft.com. Beta firmware load instructions can be found at http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 3.25 / DSP 2.21, 8-11-2009 New Features: * NOISE REDUCTION (NR) IMPROVEMENTS: Our new NR algorithm has less impact on signal strength, and should no longer make some weak signals “disappear” due to over-processing. We may fine-tune the algorithm in future releases, based on operator evaluation, but we’ve have good reports from early testers. * VFO TUNING NOISE REDUCTION: Some operators have reported hearing noise on 60, 10, or 6 meters when tuning the VFO under very quiet conditions. If you experience this, try the following: In the CONFIG:VCO MD menu entry, tap ‘1’ until you see “SPI 2” (the default is “SPI 1”). This alters the timing of data sent to the synthesizer, which in turn changes the spectrum of SPI-bus signal noise. It has no impact on performance. You will also need to add two resistors and two diodes to the bottom of the RF board (see application note on our K3 modifications web page). * AUTOMATIC RECEIVER FRONT END PROTECTION: If the K3 is operated too close to high-power transmitters, it’s possible to damage some receiver components. While this rarely happens, we’ve taken steps to prevent it by sensing a high-current condition at the mixer post-amplifier (Q8/Q9) and automatically turning off the preamp and, if necessary, turning on the attenuator. You will need to add one jumper wire on the bottom of the RF board (see application note on our K3 modifications web page). If you don’t add the jumper, operation will be unchanged; firmware can sense whether or not you’ve installed the jumper. * 10-HZ PASSBAND SHIFT STEPS (EXPERIMENTAL): If CONFIG:PB CTRL is set to SHIFT=.01 for a given operating mode, the SHIFT control will provide .01 kHz (10 Hz) steps rather than the original .05 kHz (50 Hz). Especially useful with narrow filter bandwidths. This feature is experimental and has some limitations at present: Applies to CW and DATA only; LOCUT/HICUT cannot be used when 10-Hz SHIFT steps are in effect; WIDTH steps remain 50 Hz in all cases. Not compatible with spur removal function yet (CONFIG: SIG RMV); signals mapped out may reappear. * CW SPEED DISPLAYED WITH DECODED CW TEXT: If the TEXT DEC switch parameter is set to WPM CHK (using VFO B), the speed of on-air CW signals will be shown, along with a small window of CW text. You might see “18w. CQ…”, where “18w.” means 18 WPM. Both text decode and WPM display accuracy can be improved by using narrow filtering and by careful adjustment of the “THR” (threshold) parameter (set with VFO A when the TEXT DEC switch is pressed). * RF GAIN CALIBRATION: The K3’s hardware AGC circuitry can now be calibrated. This may improve both S-meter and RF GAIN control accuracy. To do RF GAIN calibration, use revision 1.2.7.24 or later of K3 Utility (use the RF GAIN calibration function, under Configuration). This procedure calibrates both main and sub receivers. A signal source is required. Future firmware revisions will further improve accuracy, using the calibration data stored by this procedure. Misc. Improvements: * SK IS NO LONGER DISPLAYED IN RESPONSE TO NOISE DURING CW DECODE. Incorrect characters are now displayed as ‘*’. * 6 METER SCANNING NO LONGER PROHIBITED. Scanning is limited to the 6-m U.S. ham band (50-54). Exception: In some countries the K3 won’t operate on 6 m at all. * TTY CENTER FREQ NOW DISPLAYED CORRECTLY: In FSK-D and AFSK-A modes, rotating SHIFT now shows the exact center pitch (when indicated by an asterisk). The four available center pitches are 1000, 1360, 1530, and 2210 Hz. Previously the pitch was rounded down to the nearest 50 Hz. For Software Developers: * RO COMMAND (RIT/XIT OFFSET READ/SET) ADDED. This command provides a more direct way to set up the RIT/XIT offset, as an alternative to “RU” and “RD”. Set/Response format: ROs; where s is +/-, and is -. --- http://www.elecraft.com __ Elecraft mailing list Home:
[Elecraft] New K3 software 3.25 Noise Reduction works
I found the new Elecraft Untiltiy and K3 software 3.25 on the Elecraft website tonight. I live in Fargo ND and have lots of line noise and this new software is by far the best I have ever tried. I am looking forward to more CW contacts from home instead of having to go camping to hear most of the stations on the bands. Thanks Lyle.

[Elecraft] P3 Question
So I have another wonder about the P3. Being that this thing sounds like its going to have a nice display on it and a bigger display it makes me wonder if the K3 can send data to it... The reason I ask it that it may be a really cool way to augment the PSK/RTTY/CW decode functionality. Eric says that it can do spectrum and waterfall split screen. What about spectrum display and 2 or 3 lines of decoded text some day perhaps? Just food for thought. Depending on how fully integrated it is, there is a lot that the larger display being connected to the K3 could provide beyond that of just a panadapter and could make it more attractive to people who wish they had a bigger panel. ~Brett (KC7OTG) __ 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 troubles.
Hi gang, Lots of neat stuff going across here so let me add to the problem diagnosis list. I have a K3 SN 763 that is giving me fits. Multiple fits if you will. First of all i only get audio out of the stereo line out jacks when the active receiver is shown under the SUB menu. Or i susppse VFO B. I get nothing to the stereo line out jack when i'm using the A rail or VFO. Now i can get stereo audio out of the Stereo headphone jack if i gently push the jack in and wiggle it around. sounds like a bad jack to me. But i digress, at least that tells me that the headphones are good. I've not pulled any covers off YET!. Second problem. I like 6 meters and the radio performs rather well up there. Best thing that's happened to me in years, radio wise. Anyway, If i use 6 meters on the A vfo everything is peachy keen. If i shift it to the B then i hear a spur of some sort every 6 kc throughout the band. Really gets annoying. Now if i put the 6 meter antenna on the rear Rec In Ant the spurs go way donw in level but are still there. The radio is equipped with 2 receivers and a variety of filters. Doesn't seem to be anything that i can do to get rid of those spurs except to operate 6 meters on the A VFO all the time but then i don't have any audio coming out of the Line out jack to make my WSJT, ARGO, DM780 work. It only come out of the B vfo side which is where the 6 kc spurs come from. Otherwise the radio is really a great piece of engineering and i love it. Good looking as well with a bit of a steep learning curve for us guys getting up in years. Any suggestions other than operate 6 meters on the A vfo only? Btw, i to had the scratchy VFO noise when tuning around on 10 mtrs but i've not made the mod yet. I hate to keep pulling covers off of radios every other day to fix yet another problem. Not that this will happen but since i've got several of them, might as well wait and see if i can get a good fix for more than one at a time. Thanks in advance for your ear.
