Re: [Elecraft] [K2] KPA100 - Failure to be recognised - Troubleshooting question
On Aug 2, 2012, at 11:52 PM, Bill Coleman aa...@arrl.net wrote: OK, my K2/100 has been operational since October 2002. Very recently, I started to get some INFO 080 errors, and then the K2 completely failed to recognize the KPA100. Looking at it on the bench, the Vdd at Pin 1 and 20 of U1 of the KPA100 is about 1 volt. OK, if the PIC doesn't get enough voltage, it is no wonder why the K2 doesn't recognize it. I removed the U1 chip, and the voltage rises to about 1.1 volts. U3 (the voltage regulator) is warm to the touch, which tells me it is likely current limiting. Pulled U3 off the board and it tests just fine (although I'll replace it with a new part because now it is rather smoogly). Put an ohmmeter across the 5volt point and ground and I read 13.8 ohms. Hmm. That's in the ballpark. SO -- it's probably either U4 - the MAX1406 or U6 - the EL5146C chip that's gone bad and is shorted out internally. I don't see any evidence of a solder bridge or flake or other issue. I suppose I'll order some replacements. Question: Which chip should I remove first? I'm leaning toward the EL5146C, since I was getting some odd-ball power output behavior before the INFO 080 issue raised up. Plus, it has fewer pins than the MAX1406…. Any other suggestions as to why either of these chips might have failed? OK, since no one answered my original question, I will. Just so we have the records in the archives. So, to pick up, removing the 78L05 U3 device shows a resistance of about 13.8 ohms -- which is virtually a dead short for the 100 mA device. Having ordered replacement parts from Elecraft, I decided to put the 78L05 back on the board (I did test it) and try to figure out which chip was bad. Since I suspected U6 - EL5146C, it was first. Rather than trying to desolder it right away, I used a pair of wire cutters to clip pin 7. My theory was, if the 5 Volt line recovered, then U6 is bad -- if the 5 volt line is shorted, then U6 is ok and it's U4 - MAX1406. In the latter case, I could solder pin 7 back down to the pad and not try to pull it off the board. Well, one thing went wrong and one right. Clipping pin 7 on U6 resulted in the entire pin coming off the chip. Ooops. But, that was ok, because U6 was the bad chip. I clipped U6 off the board with cutters and cleared the soldering holes. Then I put a machine pin socket in place, so I can replace the chip right away whenever Elecraft ships me the parts. Now to figure out why my KAT100 is not working.

[Elecraft] [K2] KAT100 odd behavior cured by reset of KPA100?
OK, I had a failure of U6 EL5146C on my KPA100, which caused me to lose the RS-232 port, since the 5 V to power the MAX 232 chip was no longer present. Once I figured this out, I was troubleshooting the rig on the bench, and I was having trouble with the KAT100. My observations: * The KAT100 would not turn on immediately with the K2/100. It would take several seconds for it's lights to come on after the K2/100 powered on. A check of Q1 and Q2 revealed that they were working as expected. * Once on, the KAT100 would not respond to K2/100 control changes. Swinging the power control from low to high power would sometimes, but not always cause the KAT100 to change from low to high power and vice versa. * When activating the Tune or Ant1/2 functions, the K2/100 would respond with not inst. Which is weird. * Looking at the primary K2/100 Menu showed the ATU selection showing --. Pressing the display button resulted in PA Ant1 Trying to diagnose this further, I ended up going to the K2/100 Menu for the PA and turned the PA off. After this, the KAT100 responded properly to all commands, and the ATU menu showed the menu items. Turning the PA menu back on and everything works. Weird. Not sure what happened.

[Elecraft] (no subject)
Fred, Thanks for your comment. I have to assume you have a less then staller opinion of the Juma PA-100-D. Well with -28 db third order IMD this specification matches the K3-100's IMD spec. and this is with 100 watts out. All the reports I have gotton reported no problems with my signal, including those using panadaptors. You mentioned the price, well find a linear that had the same ability as the Juma PA100=D for less. It looks like it matches the new TenTech linear for around $700. I am only a consumer, I have no business interest in Juma but for a little company started by 2 hams in Finland with a lot of design and engineering experience, they look amazingly alot like another company we all know when they first started out (Elecraft). Look at the schematics and read their theory of operation before you judge the Juma products. 73 Dave KD1NA David: Who are you going to believe? Me or your lying eyes? (; While it is highly desirable to use a clean exciter, The only way a clean exciter can make a bad amp better is to enclose the amp in a feedback loop originating in the PA and terminating in the exciter. This can be done in a rig such as the K3/100 where both the amp and exciter are in the same box but is near impossible where you are dealing with 2 separate boxes. Simply: If the Juma is broke, the KX3 can't fix it. 73 Fred, AE6QL __ 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 Mics
I'm not going to try to sell anyone on the idea of buying a premium audio chain, but... I agree the K3 provides good results with about any mic that can be attached to it. It has a good compressor, useful TX equalizer, bandwidth control and a noise gate. I have obtained good results with a Yamaha CM500 and, without processing, my Heil PR40 doesn't sound substantially different from the PR40 on the K3. But I do use audio processing on the K3 and my other transmitters, for several reasons. Probably the main reason is that I can make myself sound, within the previously noted 3 kHz bandwidth, sound casually loud: optimized intelligibility without undue harshness. My station is, as are many people's, a collection of compromises controlled primarily by where I live. This is something I can tweak, and thus I am gonna tweak it... Another factor is that I like to be able to switch TX audio properties quickly to suit operating conditions. I can switch very quickly between casually loud and best-effort pile-up busting very quickly, even as a DX station is responding to me so that I can go back to normal for the exchange. I adjust my transceivers to the rack, allowing me to switch between radios very quickly and still get the same sound from all of my transmitters. This is important as every phone transmitter I have every used has subtle (sometime not-so-subtle) differences in the way they sound on the air. Finally...I just want control over this set of parameters. I probably wouldn't make the investment if it were substantially more than what I spent, but as it is I'm very happy with the price/performance ratio. And that, at the end of the day, is what counts. I can't help but notice that this isn't the cat's whisker and carbon mic mailing list, so everyone here is making some kind of price-to-performance decision and I suggest that no-one's decisions in this hobby are un-assailable.

[Elecraft] KX3 direct conversion system
Hi all, I built KX3 kit (S/N830) up last week after fixing some errors. As soon as trying some functions, I found it's really a direct conversion system. A weak leaked signal was observed with another receiver just on the watching frequency. In my boyhood, I built Mizuho DC-701 which was a copy model of Heathkit HW-7. DC-701 also adopted direct conversion system and my local station could detect my receiving point. The leaked signal from KX3 is not so strong as that of DC-701 and almost no problem. Direct conversion with DSP system will be possibly adopted in higher class transceiver. DC on 2m is interesting, however, challenging. So transverter is reasonable solution and I'm expecting the module again. Many thanks for proposing the innovated equipment. The block diagram shows the transmission system is also 'direct conversion'. The local oscillating frequency seems to be basically equal to the transmission frequency. Is it correct? Just one more twitting. The optional microphone looks something a little cheap, because it's same as that of Chinese kit KN7Qa.

[Elecraft] KX3 power wobbles
Yesterday many stations called 9K2GS. I set KX3 to max processing and started calling signing as QRP. He picked me up from many stations and gave 59. Excellent achievement for KX3. Efficient EQ + proc in KX3 is revolution in QRP radios. However, he could not copy me later. My battery dropped from 11.2 to 11V (under load), and according to LP100, KX3 reduced power from 10W to 1.5W. Must have been combination of power reduction under lower voltage plus ALC adjustments. The battery is 3S2P 4.4AH Li-Ion. Max 12.6V and smaller and lighter than LiFePO3. With current firmware, KX3 drops power from 10W to 5 W at 11V. At 11V, KX3 can switch to more efficient winding at 5 W (although the relay clicks at 3W in SSB). As the primary purpose of KX3 is portable operation, I suggest a more flexible power scheme. 1. Reduce power gradually based on voltage. May be based on lookup table. 2. Whenever the power is set to =5W, use the more efficient winding. Even though the power can be 5W at lower voltage. KX3 is an excellent radio. Played HDSDR with it and it worked very well. I will write an eham review soon. -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-power-wobbles-tp7561091.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

On 8/14/2012 8:28 PM, Joe Subich, W4TV wrote: Boost at the low frequencies is not only wasteful of transmit power, Right on, Joe. There is NO good reason to transmit ANYTHING below 200 Hz from a ham station, simply because human speech contains no energy below about 125 Hz, and frequencies below about 350 Hz contribute nothing at all to speech intelligibility. The only good contribution made by speech sounds below 500 Hz is to add some body to the voice. Since the beginnings of telephony, bandwidth has been intentionally limited to the range of 500-3,000 Hz, because that's what makes the greatest contribution to intelligibility. In general, EVERY ham transmitter should attempt to cut off everything below about 250 Hz, which is the basis of my recommendation for setting the bottom two TXEQ bands for maximum cut, doing substantial cutting of the third band, and running everything else flat (0 dB). BTW -- another VERY important reason for killing wasted power below about 250 Hz is that there's a lot of room noise, breathe pops, hum, and buzz down there. Nearly all ham mics, as well as most boom mic headsets designed for use with computers, provide a peaky boost around 3 kHz to compensate for the rolloff of the filters in telephone systems and ham transmitters. With these mics, there is no need for any boost EQ at all. This includes mics like the CM500 and the Heil mics. Mics intended for recording, sound reinforcement, and broadcast don't have that peaky boost built in, so TXEQ needs to supply it. For those mics ONLY, a good starting point is about +8dB in the highest band and perhaps +3dB in the next highest band. 73, Jim K9YC __ 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

Yes, it is similar to direct conversion, except that there are two channels (I and Q, like other SDRs), allowing for image rejection. The KX3 uses this architecture rather than superhet to provide the SDR feature, as well as to reduce the number of stages, allowing the unit to be very compact. 73, Wayne N6KR __ 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] (no subject)
David I have no opinion on Juma, the company or its products. I have no dog in this hunt. I was speaking to what I consider to be the facts. Perhaps my poor attempt at humor mislead you. I was speaking to the differences of internal versus external amps and the use of feedback. Back in amplifier school I was taught the way to make a 10 db amplifier was to design a 100 db amp and use 90 db of feedback. That's because feedback is a the miracle cure for many of the problems that plague amplifiers. And before many of my colleagues chime in I know 100 db of high power RF gain is impractical (I can do 60db with a klystron). Now my original point. The KX3 CAN NOT make any external amp better because you can not enclose the KX3 in the feedback loop. Feedback can be used with the exciter if the exciter and amp are in the same box (i.e. K3/100). That doesn't make it impossible to design a good external amp, it just makes it more difficult. It has been suggested in other threads that the Ten-Tec amp is priced higher than a KPA3 because of hardware packaging issues. This is true but it is also true that feedback issues make it is harder to design external amps than internal. Ten-Tec* or Juma* it's Apples to oranges when comparing internal to external amps and their exciters. 73 Fred, AE6QL * The claims of these manufactures are the responsibility of their respective owners.

I have to assume you have a less then staller opinion of the Juma PA-100-D. Well with -28 db third order IMD this specification matches the K3-100's IMD spec. and this is with 100 watts out. All the reports I have gotton reported no problems with my signal, including those using panadaptors. You mentioned the price, well find a linear that had the same ability as the Juma PA100=D for less. It looks like it matches the new TenTech linear for around $700. I am only a consumer, I have no business interest in Juma but for a little company started by 2 hams in Finland with a lot of design and engineering experience, they look amazingly alot like another company we all know when they first started out (Elecraft).

(; While it is highly desirable to use a clean exciter, The only way a clean exciter can make a bad amp better is to enclose the amp in a feedback loop originating in the PA and terminating in the exciter. This can be done in a rig such as the K3/100 where both the amp and exciter are in the same box but is near impossible where you are dealing with 2 separate boxes.

Re: [Elecraft] Fwd: RTTY split operation
Another way with one TNC or instance of MMTTY. Set L-MIX-R to Ab Ab. That way you get both channels out on one audio channel. In practice that works just fine for a couple reasons. The DX isn't transmitting (though lids are) when tuning. It's pretty hard to decode but the strongest pileup signals anyhow. More reliable way of finding who is being worked is being able to decode 599 in your head. It is far more reliable than hoping for any program to decode a pileup.

Re: [Elecraft] Fwd: RTTY split operation
I usually use two instances of MMTTY, one with the left channel connected to the main receiver in the K3 and the other connected to the right channel for the subreceiver. More specifically, the first instance is run in DXLab Suite's WinWarbler. By keeping the two audio streams separate you achieve the benefit of split frequency pile-up operation. The DX station is in its own decoding window, and the callers are in the other one. These days many stations continue to call even if the DX station has come back to one station and even while the DX station is still transmitting. The P3 is a big help, but stations who call continuously make it tough. It's also a problem, of course, if the callers are in your skip zone so you can hear them or see them on the P3. I think the K3's decoder is a neat feature, and I know many have used it successfully. In my opinion, it's not something I'd want to use in everyday operation. The same is true with sending RTTY with a CW paddle. For lots of help getting started with RTTY, http://aa5au.com/rtty.html is a standard reference. The RTTY reflector is also very helpful: http://lists.contesting.com/mailman/listinfo/rtty . I agree with Brian than recognizing 599 by ear is handy as is being able to tune a RTTY signal by ear. 73, Jim N7US -Original Message- Another way with one TNC or instance of MMTTY. Set L-MIX-R to Ab Ab. That way you get both channels out on one audio channel. In practice that works just fine for a couple reasons. The DX isn't transmitting (though lids are) when tuning. It's pretty hard to decode but the strongest pileup signals anyhow. More reliable way of finding who is being worked is being able to decode 599 in your head. It is far more reliable than hoping for any program to decode a pileup. Works for me. 73 de Brian/K3KO On 8/15/2012 16:12, VANO Peter wrote: RTTY split operation Hi all, Is there a simple way how to monitor two channels in RTTY mode, like in CW mode, to see the rare station working split and simultaneously find in pileup the answering station?

Re: [Elecraft] K3 Mics - ( Heil GM5)
I already had a collection of microphones before I bought my K3. They all can be made to sound fine. I use a Heil HC4 and an old Shure 444D with no TX EQ. I do have a fancy Heil PR781 but I set the TX EQ so that it sounds pretty much like an HC4, though I think it sounds better (or maybe I just want to think that). I'm in an unfinished basement with the furnace/air conditioner just across the room. The K3's TX gate is very nice. I always use VOX. 73, Jim N7US -Original Message- I am using either a Heil GM4 or GM5 mic plugged into the K3 rear jack through a Microham Microkeyer with DB37-EL-K3R cable. The Microkeyer cable mates with the Heil GM4 and GM5 Kenwood cable with no modifications. Both mics are high impedance. However, with just the Heil Kenwood cable, the GM5 works fine in the front panel connector. My setup: Rear: CONFIG rP.H - with MIC Gain 29 VOX Gain 21 AntiVox 14 or Front panel: CONFIG - FP.H with exact same settings as above.

A panadapter is a helpful tool, but when you read comments to the effect that it makes DXing like shooting fish in a barrel, you know the poster has not tried any real pileups. A panadapter doesn't tell you much when there are dozens of stations calling incessantly, both while the DX is listening and while he's transmitting. For RTTY, you can try two decoding windows as Jim recommends, or you can try to identify the station being worked by listening as others have mentioned. For CW, the panadapter may give you a clue where he is, but you can know for sure by listening. I have set up my split macro to provide a wide bandwidth on the sub-receiver, which can be quite helpful in pegging the DX's listening frequency. Skimmer is a good tool too, but for whatever reason I have never warmed up to it and I prefer the panadapter plus my right ear. Figure out where he's listening and how he's tuning, and you'll nail him with a lot less frustration and aggravation. 73, Tony KT0NY -- http://www.isb.edu/faculty/facultydir.aspx?ddlFaculty=352 __ 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

As soon as trying some functions, I found it's really a direct conversion system. A weak leaked signal was observed with another receiver just on the watching frequency. In my boyhood, I built Mizuho DC-701 which was a copy model of Heathkit HW-7. DC-701 also adopted direct conversion system and my local station could detect my receiving point. The leaked signal from KX3 is not so strong as that of DC-701 and almost no problem. Direct conversion with DSP system will be possibly adopted in higher class transceiver. DC on 2m is interesting, however, challenging. So transverter is reasonable solution and I'm expecting the module again. Many thanks for proposing the innovated equipment. The block diagram shows the transmission system is also 'direct conversion'. The local oscillating frequency seems to be basically equal to the transmission frequency. Is it correct? Just one more twitting. The optional microphone looks something a little cheap, because it's same as that of Chinese kit KN7Qa.

Re: [Elecraft] KX3 direct conversion system
Us OTs recognize this system as the reverse of the phasing system of generating SSB that was popular in the 1950's. Phasing lost popularity as low-cost and high-quality crystal filters became available because, like the KX3, they depended upon highly accurate phase shift and gain control over the entire bandwidth of the audio channel to cancel the opposite sideband. (Remember, everything then was analog, meaning building wide-band analog phase shift networks that remained stable from discrete components.) Back in the day it wasn't easy to do and achieve more than 20 or perhaps 30 dB of attenuation. That was adequate in the 50's when almost all 'phone' stations were using double-sideband a.m. occupying 6 kHz of bandwidth. In the KX3 it appears to be returning with substantially greater phase and gain accuracy, and so opposite sideband suppression, than we could achieve back then. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Wayne Burdick Sent: Wednesday, August 15, 2012 9:07 AM To: ji1...@jarl.com Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] KX3 direct conversion system 須崎 純 (Jun) wrote: I built KX3 kit (S/N830) up last week after fixing some errors.
