[Elecraft] KPA500 - A bit more info
The KPA500 uses a linear PS, with a -large- torrodial (SP?) transformer, and covers 160 - 6M. The case is the same size as the K3, with the addition of a large external fan on the right rear corner. The interest has been intense, with continuous groups of lookers. I'll try to gather more details today. It's my guess that there is smaller number of vendors here this year, a reflection of the economy in general, and California's unemployment rate stands at 12 - 17%, depending on the area.

Re: [Elecraft] P3
One other thing I will say about this. I do personally also see what Wayne/Eric/Lyle are probably up against as far as the PC+SDR juggernaut. The fight involved in forcing square pegs like a PC running Windows into a round hole like controlling a ham rig is one that most of us are simply used to from other applications and are therefore willing to keep trying. Frankly, many of us are simply accustomed to horrible general purpose designs like Windows/PC's for applications like this, there's a very strong perception that that's the way using a computer is supposed to be. Some solutions like PSK and software like cocoaModem are ingenious workarounds to this general problem, but ultimately there's still a lot of Rube Goldberg involved there that we're just accustomed to: A hard-to-use operating system talking to a broken driver talking to a USB port talking to USB-RS232 converter talking to an RS232 port on a rig talking to a. you get the idea. This is an NP-hard problem for purpose-built hardware/software solutions in general these days, even when they're very well designed and work really well. Hammering some junk Dell somewhere running garbage like Windows into the problem is often still the preferred method (usually because of cost or general availability of the hardware, etc) even when a much more elegant and effective (but proprietary and purpose-built) solution is available. So to sum up, I'm hopeful about the P3 but I also realize that there're more realistic concerns that elecraft will have to deal with here...

Re: [Elecraft] News from Visalia! (:-))
Hi, No tuner is fine me. Tuners belong at the far end of the coax, not in the shack. But is it really true that the power supply is linear? Sounds like a terrible waste of energy to me. Switchers *can* be made quiet these days. Switchers are also much more adaptible to various primary voltages. On the topic of 120/220V, of course I have nothing against 220V which is a must in Europe, as long as it will run on 120V. I do not currently have 220V in the shack but could relatively easliy install it as the breaker panel is just next door. AB2TC - AB2TC Doug Faunt N6TQS +1-510-655-8604 wrote: Does NOT!!!

Re: [Elecraft] News from Visalia! (:-))
It's nice that you bring up the SPE 1K, since it demonstrates very nicely the loss you can suffer with a built-in tuner. The ARRL review (http://www.arrl.org/files/file/protected/Group/Members/ProductReview/pdf/pr0909.pdf) said that there was 100-200W loss in the internal tuner, and presumably this is into a matched load in the laboratory. With a mismatched load the losses are generally going to be even higher. With solid-state power costing upwards of $3-$4/watt these days ($3.20 in this case), why anyone wants to leave $500-600 worth in the box is beyond me.

He said small laptop. No need for extra keyboard, monitor, etc. Also, under marginal propagation conditions with digital modes, the demodulator in the K3 is not as good as real modems that are implemented in computers. Today's laptops (and even an iPad) has much more computing power than the embedded chips in the K3, which has to do other things too. Modems implemented in computers are often written by specialists who can do better than the guys at Elecraft or Icom. And that is not to mention the lack of QPSK31, PSK63, RTTY at different shifts and baud rate (there is a 75 baud RTTY contest coming up) on the K3. Not even touching on lack of MFSK modes on the K3.

Re: [Elecraft] P3
True - like all the solutions, each is going to have its compromises and advantages. It depends on which compromise is the best fit for your intended use. My only point is the general purpose (outboard computer) solution that has the advantages of more advanced software is not necessarily cost-free. And in fact, those costs can be high enough (again depending on what you want to do and what your tolerance is for juggling 3rd party issues, etc) to warrant choosing a purpose-built solution instead. If I were still a Windows user, for example, I wouldn't even be attempting a computer based solution at all because of the fight I'd face having to use Windows and the associated SW alone (much less a completely SDR). But as a Mac user, I'm already able to use your cocoaModem and RUMLog with my K3 with very little problem at all (except for my interference issues which I have to solve in any case). But if the P3, say, could duplicate something similar without me having to use my computers and offered a truly hassle-free centralized option, I would definitely look at it. 73, LS W5QD -- View this message in context: http://n2.nabble.com/P3-tp4914382p4918360.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

[Elecraft] usb/serial Edgeport (linux)
I hate to revisit this topic so soon after the long thread died down, but this is hopefully useful for linux users. The kernel documentation states that the Edegport usb/serial port boxes are supported, but I noticed the new ones are pricey! Being too cheap for that, I bought a used Edgeport/4 converter on ebay ( $30 w/shipping) just got it yesterday. I configured the linux kernel for it ahead of time, plugged it into the laptop usb and 4 new serial ports popped up as /dev/ttyUSB[0-3]! There are 3 rigs on my desk, each needing a serial port, as well as a little line level amplifier circuit in an Altoids tin to run cw contests via the computer. All four connections run fine so it was money well spent. The box is about 4 x 7 x 1 - hardly bigger than an index card - so takes up little room is powered by usb itself. Hopefully the info is useful. 73, Mike ab3ap __ 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

Thanks Wes, You are entitled to your opinion which is sound and me, mine which is also sound. Yours seems based on long-established theory and mine based on 32 years of DX'ing practice. Maybe there should be no need for an ATU option for the K3-100? And..I would not have 342 DXCC with 100W and all with non-resonant wire. I have no physical capability for multiple resonant antennas here at my QTH. Do I /need/ an amp?...no...It's a /want /only. Plenty of folks like the SPE 1K and have said so on many forums. I'm patient and not ready to jump to conclusions here as I 'm sure its still a ways off... but If there isn't an ATU on board as I recall there was with the earlier prototypes of the bigger Elecraft amps, I wish that there were one with the KPA 500 and I'm disappointed if not, that's all. The folks at Elecraft are savvy, proficient and clever, more so than most others but they are not perfect. There is plenty of room for discussion and disagreement on points. (I'd still like to have had dedicated bandswitches on the K3.) YMMV, Offered in the form of good spirited debate. Come on guys at Visalia, we need some GOOD jpegs. 73 de N1LQ-Dave __ 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] P3
No ... I didn't oversimplify #2, at least not in terms of hardware as I stated. A laptop already includes the keyboard, monitor, and at least a rudimentary mouse. Most mouse functions for ham radio purposes are easily (some more so) performed with arrow keys anyway. Your comments on current software/drivers are valid, but in general I'm not sure that replacing clumsy software with dedicated hardware is the best overall solution. It seems to me that simple hardware and cleanly functional software is the better path. You're happy that Elecraft is offering the first path ... I'd be happier if someone offered the second one. 73, Dave AB7E On 4/17/2010 10:54 AM, lstavenhagen wrote: That's because you're dramatically oversimplifying #2 hi hi.

... but If there isn't an ATU on board as I recall there was with the earlier prototypes of the bigger Elecraft amps, I wish that there were one with the KPA 500 and I'm disappointed... The SPE internal tuner (and even the THP external tuner) can only handle about a 3:1 SWR. A wide-range autotuner needs a much greater range in component values, as well as higher voltage-rated and higher current-rated components than does a limited range tuner. Look inside a LDG-1000 or MFJ-998 and you'll see what I mean. Adding a wide-range tuner capability inside the KPA500 would add considerably to the size, cost and complexity of the KPA500. When it comes to an amplifier, I prefer an external wide-range tuner. Just my opinion.

Re: [Elecraft] P3
My point is, even with just the laptop + computer, you, for better or worse, already have 4 3rd parties involved before you ever get to use your rig: - the laptop manufacturer - the SDR/Interface software manufacturers - the OS vendor - elecraft If any of these have a problem working with each other, you've got a fair bit of work ahead of you. If it works, great, but if not If say the P3 + K3 were to work adequately for some application, say just using casual PSK and that's ok for what you want to do, that list of 3rd party vendors reduces down to one: Elecraft. Your chances of success at getting that working and well-supported are pretty good and could be a significant advantage. But Chen's point is good too and I don't want to diminish your point either. For example, I have cocoamodem running on my macbook right now scanning PSK signals from my K3 and it's just a joy to use. It is able to decode sigs I can hardly even hear out of the audio, QSYs to different stations is done with just a mouse click, it's even got integration into RUMLog, etc. and yes all with only 2 audio cords and a USB-RS232 adaptor (course the computer being a mac helps a lot hi hi).. So yes, capabilities like that available from general purpose computing are going to be a VERY tough act to follow and elecraft has its work cut out for them to compete on that level. All I'm saying is a special-purpose solution can offer (if nothing else) the single-vendor advantage and that can be significant depending on the application. It should be counted out is what I mean.. 73, LS W5QD -- View this message in context: http://n2.nabble.com/P3-tp4914382p4918618.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

Hi, Yes please, a remotable, weatherproofed 500W tuner with balanced capability would create an instant order here. Until then, I will continue to rely on my modified MFJ tuner (remote the tune function with a wire and weatherproofed in a plastic feed container). It's starting to show signs of corrosion and decay after 4 CNY winters but it's still working fine. I have a spare on hand to install when it gives out. It's cheap enough to be a throwaway item.

Re: [Elecraft] K2 Encoder problems continue.
Nidge, Is it that the last digit changes, but the K2 actually changes frequency (that would be a display problem) - OR - does the K2 frequency not move properly? Set the K2 to 40 meters. Put the internal counter probe into TP1 and set the menu for CAL FCTR. Try moving the K2 VFO dial - does the frequency move with the dial movement (it normally does). Now put the counter probe in TP3. Tap the BAND+ button and note the frequency - it should be near 12,100 kHz. Now tap the BAND- button and again note the frequency - it should now be near 12,085 or so, and it should stay there. If it fails any of those tests, you have a problem with the DC voltage being applied to the PLL Reference Oscillator. I can give you some additional points to check if that appears to be the problem. 73, Don W3FPR Nidge (Nigel Smith) wrote: Turning the dial only results in the last digit displayed flicking backward and forward. Initially it was thought that the encoder was at fault and a replacement was ordered. Unfortunately once the replacement was installed the problem persisted. It was suggested by a Don (W3FPR) that because the voltage on pin 14 of U3 to the encoder enable pin was low (only 100mV or less) that the output of this drain was faulty. Replacing the TPIC6B595N did not rectify the problem. I have checked continuity between the ENC-A/B outputs of the Encoder through the display board and back to the MCU and all checks out OK, as does the 5Volt supply. The remainder of the front panel functions work as they should. I must admit I am completely stuck now as to what else could cause this problem, especially as the radio has not missed a beat since it was constructed.

Rumor level now- The modular jack on the back is currently undefined, but is NOT just an extension of the K3 ACC connection. An ATU connnected there was mentioned. And, as I said, there's a button with an ATU label. The most knowledgeable person is no longer here, but the active devices are apparently a pair of 750W devices running at 60VDC.

Re: [Elecraft] K2 filter alignment
Nidge, Yes, you can use most any application that will give you a spectrum display. Some do not provide the features I constantly use in Spectrogram, such as the presence of 2 frequency markers that extend from the top of the display to the bottom, and the ability to place a third marker as a crosshair anywhere on the display - those plus the current cursor position give me the use of 4 markers, and the amplitude display occupies more space on the display than several others I have tried. But the real answer is YES, you can use any of them, however Tom Hammond's how to use for the K2 documentation only applies to Spectrogram version 5. 73, Don W3FPR Nidge (Nigel Smith) wrote: Hi Ed Would another FFT program be suitable.

Re: [Elecraft] k2 pll and ref osc issues n0xdb
Foxjazz, Do you have a real name and a call? We here on the Elecraft reflector certainly would like to know if you do. Q6 on what board has the bad resistance reading? The Q6 on the RF board has nothing to do with your PLL problem. Is it at TP3 that you are getting a reading of 0.00 kHz? If not, let's start from there. The most likely source of no reading at TP3 is a problem with RF Board Q19. And the problem wiht Q19 is most likely soldering somewhere in that circuit. Turn to the schematic for the RF board sheet 1 and look in the upper left quadrant (up to but not including U4) to identify all the components associated with the PLL Reference Oscillator. Check the resistance from the source of Q19 to ground - it should be close to 270 ohms - if it is higher, check the lead tinning of RFC14. You may have a solder bridge on the thermistor board (notice on the schematic that it is one of the components associated with the PLL Ref Osc). Make a quick check - the voltage on pin 5 of RF Board U6 should be very close to 1/2 the voltage on the 8 volt rail (check that at U6 pin 8). Have you checked to be certain the counter probe is still working properly? To check that, put the probe into TP2 to read the BFO frequency. If that also reads .00, you have a problem either with the probe or Control Board Q9 and/or Q10. Please be specific so we can help you better without creating a 'wild goose chase'. 73, Don W3FPR Foxjazz wrote: Hello Elecraft, Hello Don, I had the pll working before I did phase 3 and put the ssb board in.

Re: [Elecraft] KPA500 active devices!!
John, It's not shown on the datasheet. However, the VRF2933 is specified as a communications product (not a repurposed switching device) and is from the same family as the VRF150 (upgraded MRF150) which is specified at -32dBc (-38 dB to ARRL standard). Since the VFR2933 is a higher gain part (20 dB minimum gain) than the MRF150/VRF150, I would guess the IMD performance might be a bit worse at maximum output. Still, with the VRF2933 rated for 300W minimum - 375 typical at 50V - the KPA-500 is not pushing them at 500W. I'd look for IMD numbers on the mid to high 30's (ARRL spec). 73, ...

Re: [Elecraft] K2 Encoder problems continue.
Nidge, That means your problem is indeed confined to the display. It is entirely possible that you have a bad output from the MCU (CB U6) at pin 14. The most certain confirmation of that would be to replace it with another firmware chip. Yes, with a 'scope, that fact could be either confirmed or denied, but without that validation, my next best guess is for a bad output from the MCU at pin 14. If there is another K2 owner in your area who would allow you to swap Control Boards from their known working K2, that would confirm that the MCU chip is the most likely problem source, but lacking that possibility, the best recourse I can see is to obtain a replacement firmware chip from Elecraft and try that. The bottom line is that digital circuit problems are difficult to analyze without a dual trace triggered 'scope and some knowledge of the initiating events (to determine when to trigger the 'scope). 73, Don W3FPR Nidge (Nigel Smith) wrote: Hi Don and Geoff Thanks for the replies both. First of all Geoff: I'm afraid I don't have a scope here anymore. I did remove the MCU and checked the voltages, and this time on pin 14 of U3 I had the correct voltage close to 3.8V, with the MCU inserted it was below 100mV. Don: I've checked the the readings at TP1, when spinning the encoder the frequency does not change. At TP3 the frequency is close to 12,100KHz with Band + and close to 12,085KHz with Band - . I've also checked the 4MHz oscillator and this is spot on. The radio, when connected to Hamradio Deluxe works fine under computer control, both on receive and transmit. The filters are off but that's because I'm unable to fine tune them as the encoder isn't working. Any more thoughts on the matter greatfully received.

[Elecraft] K3 button problem question
Seven of my front panel buttons do not function on K3 #757. I also used the Switch Test to see that they give no scan codes. All other buttons work OK. Looking at the the schematic for the Front Panel - Switches I see these seven buttons are all connected to the SCANADC0 line into U3. I took off the front panel and put an ohmmeter from ground to the SCANADC0 line, and it gives a few ohms. The other lines (SCANADC1-7) show as open. I looks like either U3, C30, or R27 is bad. Does anyone see any other possibilities? I don't relish replacing U3 since it is a 16-pin IC. Maybe some Chip-Quik or tiny cutters to snip the leads would ease the job. 73, Paul K5ESW __ 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] k2 pll and ref osc issues n0xdb
Hello Don, Don, the call was in the subject line. Sorry for the confusion. I had the pll circuit working great with all alignments before starting on phase 3 and putting the ssb board in. As far as checking parts, the parts were correct when I checked them the second time, and the pll circuit was working. tp3 reads within tolerance. Unfortunately I broke the agc gain transistor handling the control board, so have to replace. But that shouldn't affect my issue. I was doing some voltage readings and found an issue on u5 on the rf board. pin 1 was 5 volts. U6: pin 5 was 4v on and 8 was 8 volts. tp3 reads good, and checked good. However sometimes it feels as if it doesn't check good because the band - doesn't keep the freq down on occasions. N0XDB -- mailto:fo...@foxjazz.net Saturday, April 17, 2010, 5:41:52 PM, you wrote: Foxjazz, Do you have a real name and a call? We here on the Elecraft reflector certainly would like to know if you do. Q6 on what board has the bad resistance reading? The Q6 on the RF board has nothing to do with your PLL problem. Is it at TP3 that you are getting a reading of 0.00 kHz? If not, let's start from there. The most likely source of no reading at TP3 is a problem with RF Board Q19. And the problem wiht Q19 is most likely soldering somewhere in that circuit. Turn to the schematic for the RF board sheet 1 and look in the upper left quadrant (up to but not including U4) to identify all the components associated with the PLL Reference Oscillator. Check the resistance from the source of Q19 to ground - it should be close to 270 ohms - if it is higher, check the lead tinning of RFC14. You may have a solder bridge on the thermistor board (notice on the schematic that it is one of the components associated with the PLL Ref Osc). Make a quick check - the voltage on pin 5 of RF Board U6 should be very close to 1/2 the voltage on the 8 volt rail (check that at U6 pin 8). Have you checked to be certain the counter probe is still working properly? To check that, put the probe into TP2 to read the BFO frequency. If that also reads .00, you have a problem either with the probe or Control Board Q9 and/or Q10. Please be specific so we can help you better without creating a 'wild goose chase'. 73, Don W3FPR Foxjazz wrote: Hello Elecraft, Hello Don, I had the pll working before I did phase 3 and put the ssb board in.

[Elecraft] Elecraft CW Net Announcement
Good Evening, A very nice week has come and gone again. The snow has ceased falling and sun has reappeared in the skies over Oregon. I have sat on a nearby stump and watched as the planets appeared from the glare of the sunset. Finally, after almost forty years of off and on again viewing, I have seen Mercury at this far northern latitude. Not just once but three times as it sank lower toward the sun. On the 15th I saw it with the crescent moon and Venus making a scalene triangle in the sky. Cool! Lately propagation has been getting hammered by a sequence of coronal mass ejections. Too many too often caused propagation to worsen rather than improve. When the sun quiets down just a bit the ionosphere should be well charged for our use. Hopefully the higher bands will open more often too. I have had a few contacts on 15 meters during the last month and have heard of 6 meter openings. I need to monitor that band more often. I have a loop raised for it but currently the coax is not attached to the rig. There was a thunderstorm which caused me to pull all the plugs and ground all the antenna switches. It is difficult to hear with the antennas unhooked.
