[Elecraft] Documentation to import k2 kit

[Elecraft] FS: Rohde + Schwarz CMTA84 Comm. Analyzer + RF Probeset
I have an absolutely mint Rohde + Schwarz CMTA84 1GHZ Communications Analyzer with a URV-Z7 RF Probeset. If you aren't acquainted with Rohde + Schwarz, their equipment is at the very high end of RF test gear. The CMTA84 is perfect for amatuer use because it focuses on the HF/VHF capabilities useful to us, rather than the cellular phone measurements of later analyzer. And, unlike some other analyzers that are only moderately precise, the CMTA84 was designed to R+S's high accuracy standards. This CMTA84 was purchased from Hewlett Packard and had been used by Compaq computer, which HP acquired. I do not know what Compaq did with the CMTA84 as it appeared absolutely unused. It has both the front and rear covers (rare) and the original manual, in English. Among its many other measurements, the CMTA84 has a RF voltmeter. It took me 2 years to find the matching RF probeset, the URV-Z7, which in this instance comes with two sets of 20 db and 40 db tips and the in-line bnc probe connector, which are normally accessories The URV-Z7 is rated to 1GHZ . The last URV-Z7 I saw for sale was in excess of 350 or 400 euros. The CMTA84 is an astonishing piece of equipment. Unlike later communication analyzers, this unit was built for HF and VHF equipment, it has a signal generator to 1 Ghz, two audio signal generators, a power meter good to 50 watts, an rf voltmeter, SINAD, distortion, and S/N ratio measurements, a frequency counter, a basic oscilloscope, an AF spectrum analyzer, an SSB analyzer, a RF Spectrum Monitor and much, much more. Most of the instruments are independent and they are all controlled from a OXCO. It is fully programmable, and you can do a full set of tranceiver tests by connecting the CMTA84 audio output to the microphone and the transceiver antenna to the CMTA84. It can also do tone encoding and decoding. (Tests can be automated and will even generate a report, although I have not done that, and it requires some programming.) I have put an R+S brochure at http://dl.dropbox.com/u/8297661/RS_CMT_CMTA.pdf, which provides extensive information about the capabilities of the unit. This is the best instrument on my workbench, but I find that I just am not having the time to work on projects, so it (and my other test equipment), is grossly underutilized. If you are looking for a compact unit that doesn't sacrifice quality for versatility. You should consider the CMTA84. The unit, with the URV-Z7 probeset and manual is available for $2,900 plus shipping from Alameda, CA. Please email me off reflector at hwashcr...@gmail.com if you are interested. I will be happy to provide photographs or other information to serious inquiries.

This is the sort of operating conditions that we typically set up for California QSO Party county expeditions, and that also occur at some contesting stations (like PJ2T, PJ4A, N6RO, etc.). The CQP group that I go with uses K3s driving 500w amps, wire dipoles, and tri-banders on tower trailers roughly 130 ft apart. Stations like this will typically use very good bandpass filters between the rig and the power amp (usually W3NQN filters) and also stubs following the power amp. Antennas are usually carefully arranged to minimize the coupling between them, and most contests, stations are on different bands. In CQP though, we often had a CW and SSB station on the same band. Filters don't help with that -- it takes separation of antennas. At CQP, we had one incident of actual damage to a K3. It happened because both CW and SSB were on 40M at the same time, using dipoles that were end to end with only a few feet between them. That's dumb, but we did it. :) We had no problems with both stations being on 15M or on 20M, and the year after blowing up the front end with the 40M dipoles end to end, we moved the dipoles much further apart. Also, at CQP, our tri-banders were carefully arrayed so that they were essentially parallel to each other when pointed where we intended to operate them. That greatly reduces the coupling between them as compared to pointing them at each other -- I'd guess a difference of roughly 30-50dB (30-300 times less voltage by having each in the null of the other's pattern, as opposed to 6dB of gain from each). One of the best resources on this is W2VJN's book on Managing Interstation Interference. Buy it from Inrad (the folks who sell the crystal filters) for about $25. George talks about how to calculate and how to measure the coupling between antennas, how much RF voltage it takes to cause damage, how to reduce the coupling with filters and stubs. Very solid engineering, very practical, written at a very understandable level. George is a contributor to the ARRL Handbook. 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
Re: [Elecraft] (K2) Airplane Ride
I actually prefer to keep the wheels on the ground (clean side up, dirty side down, and keep it between the lines). I know that is not as adventuresome, but it makes a shorter distance to fall. I have heard that the height of the fall is not important - the important thing is the sudden stop at the end. One does not acquire a lot of potential energy when less than 6 feet from the ground (compared to 600 feet or more). 73, Don W3FPR On 3/2/2011 10:45 PM, WILLIS COOKE wrote: > I may be an old stick in the mud but I prefer to keep the wheels pointed down > and the oil on the belly rather than the canopy. > Willis 'Cookie' Cooke > K5EWJ > > > > > > From: stan levandowski > To: l...@k0tv.com > Cc: elecraft@mailman.qth.net; plcm...@gmail.com > Sent: Wed, March 2, 2011 9:26:05 PM > Subject: Re: [Elecraft] (K2) Airplane Ride > > This might be terribly obvious (hopefully!) buta trailing wire with > a weight at the end going 100+ knots IAS is going to put quite on strain > on the K2 BNC connector ;) Might want to plan for that. > > I've been a ham 51 years and a pilot for 37.

Re: [Elecraft] Receiver Damage from another Close Station?
Before I got my K3 I had a ham move in 1000' from my antenna, and I wasn't pleased. In my previous location in AZ, I was 1700' from a ham too. In both cases, I used an ICE front-end saver, which is cheap insurance. See http://www.iceradioproducts.com/reconly.html#rflimiter . I used a Model 196, but I see they also have a model that includes a lightning arrestor / static drain, and another pair for 30-500 MHz. I'd like to hear from someone more technically qualified than I am (that means almost anyone) about the adequacy of the ICE units. My last neighbor was in a rental house. He moved out after a year, and I breathed a sigh of relief. Jim N7US -Original Message- Yes you should be concerned.

Re: [Elecraft] Receiver Damage from another Close Station?
Yes you should be concerned. I would think about bandpass filtering and probably disconnecting the K3 when not on the air. I was looking at the mods for the K3 and noticed one that addressed this issue. Are we talking city lot or 20 acre parcels?

[Elecraft] Barry Goldwater, K7UGA Operation Thursday
The Barry Goldwater Memorial Call, K7UGA, will be operational Thursday evening, March 3, using a K3. The Central Arizona DX Association will be operating the Elecraft K3 using a Buddipole antenna as part of a Club presentation and demonstration by W7ZT. We will be on 40 meters, both CW and SSB. The K3 transceiver is being offered for our use by Tom, K9CJM. We QSL 100% with special Barry Goldwater K7UGA QSLs. See K7UGA at qrz.com. CW: 7.026 - 7.028 MHz SSB: 7.185 - 7.200 MHz Our schedule is to be operational Thursday by about 6 p.m. (Mountain Standard Time) or a bit earlier. CW will be first, switching to SSB about 7:20 p.m. and will run until about 8 p.m. Here's your chance to receive a rare K7UGA QSL Card and be heard by a large crowd at the March meeting of The Central Arizona DX Association! Hope to see you in the log!

[Elecraft] Receiver Damage from another Close Station?
My next door neighbor is a ham and recently upgraded to a Icom 7700, 200 watt. The antennas for my K3 are pretty close to his. I have a set of dipoles (160, 75, 60 that share a common feedline) that are about 30 feet off one leg from the neighbor's HyTower (75 thru 10 full size vertical). I have a TH11DX up at 50 feet (boom is loaded for 40 meters also, separate feedline) and he has a TH5DX at very close to the same level, directly east of my tower, about 100 feet away. I have a Heathkit SB 220 amp (2 kw input?). Neighbor runs barefoot for now. So, my question is, do I need to be concerned about damage to either rig? I'm assuming that we can't operate the same bands at the same time. Our operating schedules seem to be very different for now. But I'm wondering if there could be input damage from one operating on any band, even if the rig is off. I was wondering if the K3 input is grounded through a relay when turned off, and similarly on the 7700. Any thoughts?

A simple trailing wire is all you need if your K2 has the built in antenna tuner. It is best if you can trail the wire from the rear most point on the plane.

Re: [Elecraft] small feature request for the K3
I think you are pretty far off the original poster's issue. He sounds like he is switching frame relays in his amps (way, way slower than regular QSK), and the regular K3 QSK timing would be several orders of improvement implemented in his amps and completely satisfactory for contest operation, as indeed it is for those I have participated in. 73, Guy.

Re: [Elecraft] (K2) Airplane Ride
Also...you cannot legally mount anything anywhere on the airplane, inside or outside, without a Form 337, signoff, etc. If it's an Experimental class aircraft then the owner/builder is the "manufacturer" in the eye of the FAA and has a great deal more latitude. Just be careful. Even a trailing wire innocently tossed out a sliightly open window has the potential to wrap itself around the elevator or rudder and bind up something.

[Elecraft] For Sale: Elecraft K2/100 with KDSP2, KIO2, KNB2
Hi there, I have a newer K2/100 (5000's serial number) with KDSP2, KIO2 and KNB2. I find that it sits on my desk and I don't use it, so I'm looking to sell and invest in more antennas. I built the K2, and it works great, but does have one small bug - the TX output spikes sometimes but I have not determined why, probably a cold solder joint somewhere? Not sure. It's relatively uncommon though. I'm open to reasonable offers. I don't know what it is worth.

Re: [Elecraft] small feature request for the K3
I haven't measured the delays, but the K3 is quite slow in QSK mode compared to my other rigs. With TX DLY set to the 8 ms minimum, my external relays hang between the dots above about 35 wpm. The relays are very fast (1.4 ms); it's the K3 control output that isn't switching. It would help if the TX DLY could be set to less than 8 ms. I don't see where tail delay is specified, though I presume it is tied to TX DLY. QRQ mode helps, but it's still not as fast as with the FT-1000. I also hate to give up the RIT, etc. just to have better QSK at 40 wpm. Independent control of leading-edge and tail delay would be optimal. Does anyone know what the tail delay is, and whether it tracks the TX DLY setting? 73, Scott K9MA On Mar 2, 2011, at 11:41 AM, Guy Olinger K2AV wrote: > Would't you be far better off to improve your amplifier(s) to QSK operation? > Or alternatively, some Microham boxes will do that for you by plugging the > paddle into the Microham box instead of the rig.

Re: [Elecraft] small feature request for the K3
Would't you be far better off to improve your amplifier(s) to QSK operation? Or alternatively, some Microham boxes will do that for you by plugging the paddle into the Microham box instead of the rig. That's what I do if I have to use a non-QSK backup amp. I enter those delay parameters into the win-key section of the logging program, or if it does not handle that, into the uHam router program. 73, Guy.

Re: [Elecraft] (K2) Airplane Ride
Can I wish you good luck connecting to your ground system? On a serious note, more information would help. What bands, and what antenna are you planning on using? What modes? (In a small plane, operating a voice mode will require mics and earphones that are seriously noise canceling -- not the usual stuff we see in amateur radio.) You should also talk to the pilot/owner of the aircraft before doing a whole lot of planning.

Re: [Elecraft] Enable 60m transmit
I discovered that the my K3 would indeed transmit between 5330-5407. So my question should have been how to expand the transmit range to 5260-5410 kHz (the TF allocation) I was sent privately a link to a file which helped me unlock my K3. Perhaps it would be better if the transmit range was updated via firmware? Problem solved.

Distortion should be low if you are using a proper interface and adjusting audio levels properly. With the K2, that means an interface that includes a simple 20 dB attenuator (resistive voltage divider) between the sound card output and the mic input. The sound card output level should be set at least 6dB below its max output voltage, and the K2 mic gain should be set just below the point where output power starts to level off. To set the sound card output level with a scope, look at the waveform at the output of the sound card while sending tones from the RTTY program, increase level until you just begin to see clipping, then reduce the voltage by one half. If you don't have a scope, LISTEN carefully to the tones as you increase the level. At some point, the SOUND of the tones will get "brighter" or "harsh." That's clipping. Now, back off the level until it sounds "half as loud." That's where you want to run the sound card. This setup procedure works for ANY rig and ANY sound card, not only the K2. 73, Jim Brown 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

[Elecraft] small feature request for the K3
Hi Elecraft I?m using my K3 99% for CW-Contesting and am optimizing my switch over timing between, Trasnceiver, PA and so on. When running with the contestsoftware (WinTest) there is an exact PTT-Signal switching TRX and PA before sending CW (PTT on Delay) and after the last CW-character the PTT-line drops as fast as possible to not lose the prefix of a calling station (so no PTT tail delay). But sometimes you need to send CW with a manual keyer (internal or external) and there is no PTT on delay now and no PTT tail delay. Today we are solving the problem by using a footswitch for this "manual" operation times. Wouldn?t it be possible for the K3 firmware to have different delay time entries (for PTT ON and PTT OFF) between using the serial port keying and using the Key Ports on the back side (Paddle with the internal Keyer or even with an external keyer)? 73 de Wolfgang DK9VZ __ 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] [Bulk] Re: [Bulk] [K2] Loose screws on KPA100 Q1 and Q2
Bill, It is a matter of practical consideration. Most K2 BFO ranges will support a LSB filter width of 400 Hz centered at 1000 Hz. but not much more, although some have to be padded a bit to obtain that sufficient range. The USB filter is typically no problem, but RTTY is usually LSB. Narrow filters are usually more important for RTTY than they are for other data modes. Yes, you are correct, images could be a problem if the transmit audio is overdriving the KSB2, but then I look at that problem as an operator consideration, and can be corrected easily - the K2 operates in a linear mode if it is not overdriven. MMTTY conveniently provides for a mark frequency of 910 Hz. That is the one to use with the K2. 73, Don W3FPR On 3/2/2011 8:06 AM, Bill Coleman wrote: > On Mar 1, 2011, at 9:30 PM, Don Wilhelm wrote: > >> My recommended RTTY filter set settings are - FL1 = The same as the SSB FL1 >> settings - that gives you the full waterfall display - FL2 = 1.00, FL3 = >> 0.70, and FL4 = 0.40.

Don, As much as I hate to contradict your expertise -- are you sure it is wise to use such a low center frequency for AFSK RTTY?

The SDR-IQ is supported with "SpectraVue" (http://www.moetronix.com/svdownload.htm) and SDR Console, (http://www.sdr-radio.com/Home/Introduction/tabid/384/language/en-US/Default.aspx). I use SpectraVue as it does everything I need with a clean interface. SDR-Console is still being tested and there is a new version (or two) every day. It's way too cluttered and complicated for me, but I guess some folks who think Hamradio Deluxe is fine, probably love it. QUISK (http://james.ahlstrom.name/quisk/) is another one, but I haven't tried it. Winrad (http://www.winrad.org/) is another one I haven't tried and may have died by now. The interface spec and architecture is documented for all to see.

[Elecraft] K3/100 and 160 meters
Propagation was really good for a short while on 160 this morning. JR7VHZ was running S7 to S9 and there were many US stations calling him. He was having QRN/QSB trouble on his end, but the band was very quiet here (I discovered later that my attenuator was on and the preamp was off!). Surprisingly, I got him on the third call and had to repeat my call for him a couple times as the E in W0EB kept getting lost in his QRN but it proves that you do NOT need high power on 160 to work DX. The antenna I used was an inverted L that has no radials under it. The vertical portion is only about 27 feet and the horizontal part slopes upward to about 35 feet to the top of a big pine tree in my front yard. Now, if I could just break the East Coast KW barrier into Europe. A KPA500 would probably help a bit there - LOL. - ;) The L's broadside favors Japan and the Caribbean. The P3 really helped here too as I saw the spike when he first started calling CQ around 1812.4KHz. I had been calling CQ in RTTY on 1808.5 hoping to catch a quick QSO. Haven't heard any PSK on the bottom end of 160 yet, but I've worked several RTTY stations that hang out around 1808 or so.

[Elecraft] FS: K3/100
I've decided to sell my K3/100, as money is needed elsewhere (2 year pay freezes tend to do that). I built it from a kit (#428), and includes: KXV3 (not 'A' version) (RX in/out, transverter interface, IF out) KBPF3 (general coverage bandpass module) FL3A-500 Hz 5 pole FL3A-2.7 kHz (standard) As many manuals as I can find, if desired It is up-to-date on all firmware, and I believe all but one or two mods (that didn't apply to my operating; I have notes). I've used it on most bands, in CW, SSB & digital, plus a lot of non-ham band monitoring. It is in excellent condition, and comes from a non-smoking home. It's never been in the field, and has had a dust cover since day 1. Pictures can be seen at http://myplace.frontier.com/~kw1nd/k3.html Price is $1875, including insured shipping in US, likely via FedEx Ground. PayPal or USPS money order accepted. A signature will be required upon receipt. Shipping elsewhere will be actual cost, and determined upon a firm offer to buy.

[Elecraft] P3, what lies ahead?
Jack, Firstly, my knowledge of PSDR is second-hand as I have not downloaded it or used it (yet). It was compared to other sw by a fellow eme ham for sensitivity and found lacking when compared to other sw. I am aware it was expressly written for Flex radios so some features will not be applicable to other radios. As I understand there is a "stripped" version for use on the LP-Pan. I was not suggesting to export analog signals from the P3. Instead digital I/Q data-stream is what is desirable as that can be directly input to sw running in a PC. As far as I know the P3 has no D/A, but directly converts the K3 IF to I/Q baseband which is converted to digital data. For example my SDR-IQ can be connected to the K3 and does not use a soundcard input to the PC (it uses USB2.0). Spectravue provides demodulation for input to the PC soundcard for audio output. The LP-pan is a simpler device having no A/D so one must use a soundcard with their limitations (but I am hoping that it will be adequate for dual-polarity diversity reception up to 96-kHz bandwidth). I am using the 4-port Delta-44 sound card with two LP-Pan. One can probably design a better SDR than the LP-Pan, these days. If one only wants to export the P3 as a panadaptor on PC, then your scheme is fine. Some of use have use for the I/Q datastream for input to other DSP sw which is more effective/powerful for signal processing and signal detection/demod. That is why I lean toward the export of the I/Q datastream. I suppose remote control of the P3/K3 via an USB connection might be added do what you want. SDR that are restricted to running only the in-house sw (firmware) miss the boat on the promise of open-source SDR. As far as I know the SDR-IQ, Flex-SDR's and the K3 do not allow for alternative sw to be written for them. If I am wrong in this impression then please tell us all. -- Message: 12 Date: Mon, 28 Feb 2011 11:19:13 -0600 From: Jack Brabham Subject: Re: [Elecraft] P3, what lies ahead? To: elecraft@mailman.qth.net Message-ID: <4d6bd911.3040...@att.net> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Ed, I run LP-PAN and PSDR/IF and find them indispensable, particularly during contests. These days it doesn't feel like the K3 is fully "ON" until PSDR/IF comes up. On the other hand, I'm always looking for ways to reduce the number of boxes and software packages in use. Exporting analog IQ signals from the P3 does not appear to be terribly useful as this just makes the P3 an equivalent to LP-PAN and would still require PSDR/IF and EMU 0202 or something similar. From my limited understanding, one of the operational advantages of the P3 is that it is not tied to traditional sound card scan frequencies, 192 kb, 96 kb, etc., a big P3 plus that would be lost. My idea is more along the line of leaving everything except the display and user interface physically in the P3 "Blackbox" and replacing those with a PC application that provides the display and controls.That way the tight integration with the K3 is maintained and is enhanced by the addition direct integration with the PC. For instance the "point and click" tuning that is sooo useful when S&P'ing a band would become a P3 feature (I realize that it can "sort of" do that now). Point and click tuning combined with the P3's unique ability to fix the displayed segment and let the VFO cursors "float" would a wet dream setup for RTTY contesting. PSDR/IF makes a valiant effort to "approach" that idea, but has some significant limitations due to being fundamentally designed for a different radio. IMHO it also suffers from being too "SDR-centric", for example when there are conflicts between the radio's setting and PSDR/IF's, PSDR/IF will resolve them in it's favor rather than following the K3.Consequently I have to leave a some of PSDR/IF's "features" disabled to get it to "follow" instead of "lead". The base program was designed to support a blackbox SDR (Flex) with no physical controls, so that is understandable but still a problem. While I'm wishing, if the blackbox P3 fit inside the K3 it would be really great. Maybe with a new KIO3 that had (gasp) a USB connector. From a customer perspective, I would find a blackbox P3 with an associated PC application a much more compelling and valuable product. 73 Jack KZ5A 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw, 432-100w, 1296-testing*, 3400-winter?
