I will do that. I thought of that, but it is late and I am tired of chasing the problems down while having fun with it. Thanks for the help!

It might sound better to call it that but it's still the same thing ... intentionally putting a trashy signal on the band. Want to be distinctive on the bands? Say something clever, useful, informative, interesting, funny ... whatever. Leave the junk signals in the past where they belong.

Perhaps we could call it, "personalize our transmitted CW note?" Sounds better than "dirty up." And, this is NOT a request for a K3 firmware change to allow personalization of CW notes! Rotary spark operators sometimes had a foot pedal similar to a sewing machine pedal with which they could "personalize" the note [such as a "note" was with a rotary spark gap TX] by speeding it up and slowing it down while sending. What truly intrigues me is how they built receivers pre-De Forest. Spark gap TX is easy, before LORAN-C met it's death, several of the stations had reverted to the 21st Century equivalent of spark. I really do not understand what the Titanic's receiver looked like. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org __ 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] OT-old vs. new 6L6 to K3
When I got my first Knight-kit VFO, I got a lot of guffaws from my local crowd because my signal had a chirp. I worked with my elmer (first class commercial license and chief engineer at WCTT) to solve the problem with keying the VFO, and was so proud of the clean signal when I was done. No clicks, no chirps, no mush. That was 1958 and all the hams I knew, were well informed about what a clean signal was. Mushy, clicky, youpy, chirpy signals got ridiculed, no less then than now. But maybe things were different in Kentucky?? 73, Guy.

Real specifications for this are quantities like the Transfer Impedance, which is the ratio between the differential voltage inside the coax as a result of current on the outside of the coax. That ratio varies a LOT as a function of frequency. The lower the value of that transfer impedance, the better the shielding. The lower limit on the transfer impedance is the resistance of the shield. 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, accidentally at N6A in the 2011 Cal QSO Party. There was no lockout mechanism, it was late at night, it was the first time we'd ever done an M/2 operation, and we probably should have known better, we had over 200 years of combined ham experience aboard. Is there any danger of damaging the receiver(s) by > transmitting with high power so close by (different antenna, same > property). Yes, we fried the PIN diodes in the K3 front end. The other rig was an ICOM Pro and the K3 was never keyed so it survived. Is there a difference if the transmission is a few KHz away vs > (accidentally) on the same frequency? Depends. The critical issue is whether or not the antennas are in each others near field. If they are, they become coupled elements just as parasitic elements in a beam are coupled to the driven element. Coupled power in antenna 2 from same-band antenna 1 can then be large enough to fry the input circuits. The size of an antenna's near field is roughly, kind of proportional to the gross size of the antenna. Thus, lower frequency antennas, being larger, have a larger near field than higher frequency antennas. The two 80/75 meter antennas [Inverted V's] at N6A were definitely in each other's near field, something that won't happen this year. :-) It doesn't matter where the two radios are tuned in the band. The damage happens at the very front end, often in the diodes of the TR switch or the first RF amp device. If the antennas are definitely NOT in each other's near fields, you probably won't sustain any physical damage. Whether or not the radios can be used will then depend on their dynamic blocking and IMD characteristics. Jack, KF6T, is about 2 km from my station and runs legal limit. With a Kenwood TS-850, I could not operate on the same band with him, I heard his keying all over the band at 30 over, generated in my receiver. With my K2, I can get within 3 or 4 KHz before I begin to hear products. With my K3, I can get within a KHz or less. > > Just curious what sorts of precautions (if any) ought to be taken and what > solutions exist (if necessary). 1. Make certain the two antennas are definitely NOT in each others near fields. When BPL was a real possibility, I modeled the power lines near us and my antenna with EZNEC4. It indicated a coupling factor [the loss between my power and what would show up in the power line] of about -35 to-38 dB on all bands except 160. There, it was -15 dB, because at 160, the antenna and the distribution lines were in each others near fields. 2.

Jim, I think you may have answered a question that's been on my mind for years. Some time ago an advertisement for coax cable in QST said that a certain cable had "80 dB shielding". I had never seen a spec for this before. Could they have been referring to the leakage from inside to outside; outside to inside (as you were describing); or both? Or something else?

I also had 'variable xtals' that you could move several hundred cycles ( or hertz) to move away from an existing QSO. Then the Heathkit VFO became available WOW!

My first experiences were on county expeditions for the California QSO Party, with four K3s feeding two KPA500s, a Ten Tec Herc II, and a 600W Yaesu amp. We had tribanders pointed roughly 70 degrees, carefully located so that they were at 90 degrees to each other, and were able to run one on CW with the other on SSB on the same band on 15 and 20M. The stations would hear each other at about S6-7, so we could work the roughly 60% of signals that were louder than that, then we would have one change bands so that both could work the weaker ones. At home, I have a 3-el SteppIR at 120 ft on one tower, monobanders for 20 and 15 at about 40 ft on a tower about 150 ft away, and a 4-el 10M Yagi about 50 ft further from the SteppIR. During contests, I run Ten Tec Titan amps at legal power with two K3s. All of my antennas are fed with either CATV hard line or Heliax for most of their run, and everything else, including all patch cables inside the shack, is on very good RG213 with soldered Amphenol PL259s. With those Yagis optimally aimed to reject each other, I can operate as close as 50 kHz on 20, 15, and 10 and not know the other station is there. Pointing one at the other is another story, and can cause the receiving K3 to turn off the preamp and turn on the attenuator, but I can still work strong stations through my own QRM. I mentioned the quality of my coax because that is quite important when you're trying to get a lot of rejection. Poor connections, or poorly shielded coax, or both, can couple common mode current from the outside of the coax to the inside of the coax at low levels. Coax shielding is a function of the resistance of the shield, the density of the shield, and the uniformity of the shield. Thanks to skin effect, the larger the diameter of the coax the lower the RF resistance of the shield, assuming a shield of the same quality. 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] OT-old vs. new 6L6 to K3
Has anyone else noticed that the cw elements produced by the K3 are distinctive? They are sharp and distinct, without any mushiness. The signal has presence, and yet not a trace of clickiness, on or off frequency. There is the highest degree of purity of tone, as well. OK, back to my day job as a wine taster.

Re: [Elecraft] two k3's on the same band
The West Valley Amateur Radio Association used K3s last year for the CW part of our field day operation. We also had an active digital station on the same band, so there was not much frequency difference. We were operating QRP at 5 watts. I think our antennas were closer than the 300 feet Tom, N4ZPT reported for the Vienna Wireless Society operation. I did not hear any complaints from the CW operators, although we did get interference from the digital station with our SSB operation (which was not using Elecraft equipment).

Re: [Elecraft] two k3's on the same band
Matt, The multi-op NI5T operation in the CQ 160 contests at the N5BG station are done in the manner you are inquiring about. We run THREE K3s, one running and two S&P on Topband, all three transmitting with full 1.5 kW output power. Granted, we exclusively use Beverage antennas for receiving, and the Beverage field is at some distance from the TX antenna. We copy stations with the S&P positions to within a few kHz of the CQing position. Many times we operate in full duplex on the same freq, with one of the S&P positions listening on the CQ frequency in a different direction than the CQ position is listening. This allows us to listen in multiple directions with the Beverages. We do not and have never had any problem doing this with the K3s or with the lineup of FT-1000 MPs we previously used. Never a single instance of receiver damage while operating in this manner the past ~13 years. The KEY to successful in-band duplex operation is ISOLATION, either by polarity or physical antenna separation, or both. YMMV, and good luck with your trial. 73 de Milt, N5IA -Original Message- From: Matt Murphy Sent: Wednesday, March 21, 2012 12:24 PM To: Elecraft Reflector Subject: [Elecraft] two k3's on the same band Just wondering if anyone has any experience using two K3's on the same band (for example, one for running, one for mults in a multi-op single transmitter scenario).

Re: [Elecraft] two k3's on the same band
Matt, At PI4D we have two beams that can work on 20m: a 5L monobander and a FB-53 (5L tribander). The beams are about 75m (220ft) apart. Worst case scenario(beams pointing towards each other): running 1kW in the monobander we measured a 9W signal on the FB-53. Yes, you have to take precautions. We did this once. Solution: when one station is on the air, the other is keyed by ptt (shutting down the RX) without possibility for transmission (disconnecting ptt of the linear amp and the microphone- and cw-inputs). Worked just fine. 73, Arie PA3A Op 21-3-2012 20:24, Matt Murphy schreef: > Just wondering if anyone has any experience using two K3's on the same band > (for example, one for running, one for mults in a multi-op single > transmitter scenario).

Re: [Elecraft] OT-old vs. new 6L6 to K3
I also used that Tri-Tet circuit in my first Novice rig. I was able to listen to the keying thanks to a buddy a few miles away. We'd talk on the telephone while keying our rigs to hear what they actually sounded like. It can be run with very, very little chirp on the lower frequency bands. The chirp is directly proportional to power output and, in a time when "yooping" signals were common, the desire to increase the loading to pump up the RF output often overcame concerns about signal quality. So most of us balanced output and chirp at then-acceptable levels. For many, as long as it would start oscillating when the key was closed, it was good enough, Hi! Later, I successfully used the much newer 6146 and even a 5763 in one-lung oscillators on 40 and 20 meters without detectable chirp. The newer higher gain beam power tubes were much easier to "tame" than the earlier 6L6, 6V6 and 807. Building a one-tube transmitter that didn't have detectable chirp was an interesting design challenge in the 1960's. Also the chirp depended greatly on the frequency. He used a 40 meter crystal multiplying the frequency by 4 to reach ten meters. That means the chirp is four times worse too! I would not have expected any better from my rigs. We can cram a lot more signals into the bands these days. Putting more signals in less spectrum has been a challenge for Hams since the 1920's. But us OT's are often a bit nostalgic for CW bands where one could recognize a station by the sound of his (or her) signal and "fist". Back then a CW band sounded like a room full of people, each with a distinctive voice that could be picked out easily even without listening to the words. Nowadays the same CW bands sound like a room full of computer-generated voices, all identical except for the words. And, with the digital modes, there aren't even any words to hear.

Re: [Elecraft] two k3's on the same band
Yes. Vienna Wireless Society K4XY Field Day multiple times. We had an all K3 field day couple times with 2 K3s on 40m. One CW and one SSB. Antennas were dipoles or two element wire yagis both pointing West with about 300 ft separation E-W ( yea, CW station was in the beam of the SSB station]. Either K3 could dial close to the other with little issue. When we tuned past the other station was just a strong station.

Jack,
Make sure you set everything to 38.400 bps - SteppIR, K3, P3 and
Commander's Primary CAT Serial Port. Connect the SteppIR "Y" cable
between the K3 and P3 ("computer" connection to the P3) and the
Elecraft USB adapter to the P3 RS-232 input.
Essentially the system is linear: Computer <-> P3 <-> K3 with the
SteppIR tapped off between the P3 and K3.

Re: [Elecraft] OT-old vs. new 6L6 to K3
This is one oldtimer who actually used such a design. After more than 58 years I finally understand how it worked .. actually, not very well for me. Chirps and whoops were very common in those days and I can say with confidence that they were definitely acceptable and, in fact, were a characteristic of stations such as mine without the operator even knowing about the whoop. Remember, like many other novices I was using a simple regenerative receiver that could not be used for a monitor and never knew how my signal actually sounded in the other guys receiver. Even the more sophisticated superhets overloaded so easily that they did not provide a faithful reproduction of the outgoing rf.

[Elecraft] P3 SVGA
UPS showed up 20 minutes ago with my new P3SVGA board. Took about 15 minutes to install it. The power supply I use for the station has some AUX terminals on the back that are good for 5 amps so it was really easy to hook the new power cord supplied with the SVGA unit to those terminals. Now, when I switch the power supply on, the P3 comes up and waits for the K3 to be powered up. A little clunky, but once the mod is available to make the K3 supply a bit more current, I'll do that and then everything will be back to normal again. I have to wait til Friday to hook up the monitor as it's in transit from a supplier on the East Coast and UPS says it will be delivered on Friday the 23rd. Still a heck of a lot of room in the box for other stuff! Will be glad when they get the new F/W done so I can use an external keyboard with it for the DATA modes. That will make it a lot easier to demo at hamfests even though I really have fun sending CW on the paddles and working PSK or RTTY. Certainly turns a few heads, but those newer hams that haven't any CW skills get turned off by that, so the KB sure will make a better demo.

Re: [Elecraft] P3 SVGA
Hi Bill, The SVGA hardware allows the waterfall height to be set much higher than what is available on the P3. Until we have the ability to independently set the waterfall height on each display, we wanted customers to be able to take advantage of this feature. 73, Paul -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-SVGA-tp7367327p7392692.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] OT-old vs. new 6L6 to K3
Your right John but remember many hams were kids saving dimes from collecting old newspapers,, 34 was in the middle of the depression and MOPA used a lot of parts and over all considering he is keying the xtal not a bad sounding signal for real fun check the Antique Wireless Association OT contest,, should be a pre 30 rig design and using a 45 was High Power,, a 27 worked almost as good,, the power isset to be under 10 watts for the contest and my 80 meter Harley will chirp out of a modern rcv bandwidth although that really is excessive HAR many guys have surprisingly stable rigs with just a handful of parts real fun is listening to guys trying to get them on frequency Bob K3DJC On Wed, 21 Mar 2012 09:24:07 -0400 John Ragle writes: > The 6L6 keyed oscillator shown in the Flickr page is certainly a > lovingly-crafted piece of artwork, but I am a bit skeptical about > the > implication that a techno-adept ham of the late '30's would have > been > pleased by the chirp.

[Elecraft] FS CG-3000 Automatic Remote Tuner - as is
I have for sale a CG-3000 Automatic remote antenna tuner. This unit is functional, and just recently removed it from an antenna that I am no longer using. I purchased the unit new in 2008 from Array Solutions and it has been working flawlessly since then in my application of tuning verticals and inverted Ls. It has been installed outdoors at the base of a tree in my back yard. I'm listing (and pricing it) as "as is" for two reasons. It has been out in the weather for over 3 years so cosmetically it isn't great. The label on the top surface, for example, is completely worn away. Secondly, when I just now tested it in preparation for selling, it seems to only obtain a SWR of 3:1 rather than the speced 2:1 on 10 meters. Only tested on one antenna and perhaps my K3 SWR metering isn't as accurate on this band. I've never used it on 10 meters, so don't have any historical reference point. It works fine on the other bands, matching a 37 ft vertical to SWRs from 1.1 to 1.6 on all bands 80 through 12 meters. I've used it successfully in the past on 160 meter inverted Ls. The unit is completely automatic. It tunes by sampling the RF input, and requires a minimum of 10W and is therefore not suitable for QRP. I have the tune power of my K3 set to 13W and this has always worked just fine. It has 200 memories for storing previous frequencies so subsequent tuning is very fast. Power rating is 200W. Rated to operate from 1.8 to 30 MHz. Requires 12 to 14 Vdc power supply. I've been just running a two conductor cable for this purpose, but you could also use a bias-T on the coax. Average operating current is 0.5A, but you should have up to 1A available for instances when several of the tuning relays activate at once. For additional information see www.cgantenna.com and also the eham reviews. Just now opened it up again and verified that everything inside is in pristine condition. Absolutely no sign of water intrusion, probably due to the good gasketing of the top cover. Original owners manual (sparse) is included as well as some additional technical and applications info I've found on the web. It appears possible to construct a control head to manually initiate tuning via a 3 conductor power/control cable, but I have not tried this. This unit should provide an inexpensive but serviceable remote tuning solution for many applications. Not in same league as the upcoming KAT500, however. Price is $100 via PayPal plus UPS ground shipping. Shipping weight should be 7 pounds from 80503 zip. If you have interest or questions, contact me directly via Email. 73CraigAC0DS __ 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] OT-old vs. new 6L6 to K3
But you are hearing it on 10 meters. Down on the fundamental (I didn't check the schematic - sorry) it probably sounded much better. Myself, I would have tuned the other side of zero beat so the chirp went the other direction. Pure music! Open up that K3 all the way, sit back and relax, and listen to the music.

Re: [Elecraft] OT-old vs. new 6L6 to K3
The 6L6 keyed oscillator shown in the Flickr page is certainly a lovingly-crafted piece of artwork, but I am a bit skeptical about the implication that a techno-adept ham of the late '30's would have been pleased by the chirp. After all, the 6L6 first appeared in 1936, and by then the 'x' and 'c' of the RST/x/c reporting scheme was probably already in use. Keying an oscillator working directly into an antenna was understood to be a poor idea. The MOPA idea was around long before the 6L6. There is a QST article in 1934 illustrating the general idea of a 2-stage transmitter, and the idea was known long before that.

Many will enjoy the video and photograph in the attached link to my Flickr page. It features a photograph of a beautifully crafted 1930's designed single tube transmitter and how it sounds on a state of the art crafted K3 :) Click on the K3 to hear VE7SL/QRP. http://www.flickr.com/photos/ak5x/ Steve, VE7SL is the craftsman of this beautiful transmitter and has just posted details on his web page (link below).
