Re: [Elecraft] Contest Reflections
To some degree there is a bit of speed snobbery out there. I too am comfortable as 13-15 wpm. Too often, someone will return on my cq at about 20. I do my best but it just isn't fun. I can't copy in my head and I have arthritis in my hands and can't write faster than about 15. The best solution is to join FISTS and work lots of FISTS stations. These guys and girls are a real pleasure and helped me make cw an enjoyable mode to operate. 73 - Doug --K0DXV Sam Morgan wrote: J F wrote: Doug, 1. QSK. This is user skill level dependent.

[Elecraft] Sony MDR series headphones for KX1
I own a really old pair of MDR-7506's that must be at least 10 years old now. I use them for DJ'n and love them but I wouldn't want to use them for my KX1. They probably would draw too much power. I bought recently a pair of Bose headphones for my iPod because I was working in a data center and the fan noise is REALLY loud. At first I was looking for noise canceling headphones but I didn't like any of them I tried and I got a pair of Bose over ear headphones like these: http://www.bose.com/controller?event=VIEW_PRODUCT_PAGE_EVENT&product=triport_ae_headphones_index I HIGHLY recommend them. They are very lightweight, and sound awesome. They also almost seal around your ears making them pretty good in noisy areas. They aren't the cheapest thing in the world, but I would take them over lots of other headphones I have used, including AKG sealed studio headphones, and the only other style I've used that I liked better were a friends pair of Sony ear buds but they costed like $400. -Chris --- Tom McCulloch <[EMAIL PROTECTED]> wrote: > Here is a review of the MDR-NC50 -- They say its > pretty good but apparently > needs some oomph to drive them and not great for MP3 > players which don't > have a lot of output: > > http://reviews.cnet.com/headphones-headsets/sony-mdr-nc50/4505-6468_7-31294268.html > > And more of the same comments at: > > http://review.zdnet.com/headphones-headsets/sony-mdr-nc50/4505-6468_16-31294268.html > > > I'd love a nice pair of noise canceling headphones > that can be used on my K2 > and MP3 player -- anyone have any ideas. > Tom > WB2QDG > k2 1103 > MP3 - Creative > > - Original Message - > From: "john shadle" <[EMAIL PROTECTED]> > To: > Sent: Tuesday, May 29, 2007 4:31 PM > Subject: [Elecraft] Sony MDR series headphones for > KX1 > > > > Saw a mention on this list as well as in the > manual about these > > headphones.

Re: [Elecraft] Contest Reflections
Sam, I think there are more than a few who feel the way you do. Generally, if some one comes back to me slow when I'm running, I'll drop my speed some, probably above what they were sending at, but slow enough where I think they can get the exchange right the first time. Lately, I've noticed a lot of folks who send quite slow and I speculate these are first time contesters. I figure they want to learn the game, but may get frustrated if blown out of the water. In my mind it's better to slow down, make a solid contact and let the other guy feel good about it as well. The last few big contests I picked up some nice multipliers from guys who were sending slow with pileups on them, not because I was the loudest, but because I sent at a rate they could copy... > > My cw qso speed is a comfy 13-15wpm. > I can sorta copy (75%) at about 20-22wpm. > > Above that I have to listen to the guy as many times > as it takes, > sometime 10 or more, just to get his call and the > exchange info, > so when/if I answer him he won't have to deal with > my requests for repeats. This is a good way to pick up your speed. Much easier if the signal is solid, generally one of the superstations. I'd say the vast majority of contesters run in the mid 20 WPM to the low 30s... Some of the Eastern and Southern EU will crank 40+. Some exchanges are a lot easier to recognize than others at those rates. > > Is that a fun way to contest? no. If it's not fun, pass 'em by... Of course, not everything in a contest is "fun". How you want to play makes it fun. It's a rush to get a run going and working smoothly, it's a lot of fun to find a rare one all by his lonesome. The vast majority of the folks who play great. Like everything else in life, there are those who you wish weren't involved. > I just wonder how many q's they miss out on in doing > so? It's an interesting question and would make for an interesting study. Assuming you could get unbiased reporting from both sides, it might change the perspective of some. Hope to catch you in one of the contests. Don't be afraid to send QRS if ya need to.

[Elecraft] [K1-2277} Front Panel construction -- R1 (10-turn potentiometer) numbering confusion
Hello all. I'm seeing a difference between the numbering diagram and the numbering on my potentiometer. I'm thinking I should follow the numbers. The sequence on the potentiometer shows 1 and 3 on the outsides, and 2 in the middle and pointing to the center of a resistor symbol. The manual illustration shows 3 and 2 on the outside and 1 in the middle. Both show 3 next to the knob shaft. The manual also notes that "Your potentiometer MAY be either of the two types shown." (Emphasis added). I have three in-line lugs. >From the front panel schematic in Appendix B, I think I just need to match the diagram on the pot with the schematic, but it is not clear which, 1 or 3, is the ground on the pot. The schematic on the pot indicates that CW moves towards 3. Thinking that this is simply a variable resistor, I'm thinking that getting the "variable" right is the key. Trying to learn as I go.

[Elecraft] Re: K1-2 No TX on one band
Well, I think I have this one sorted out. Here's how it boiled down for me, in case anyone else gets anything similar: 1) Reflowed *every* solder joint on the filter board. Added a bit of solder to the ones that looked like they could handle a little more 2) Reinstalled the filterboard and experienced *no* change (still 9.9:1swr, no appreciable power out). 3) Tuned around to find some kind of signal. 4) Repeaked the filters (they did take a bit of adjusting, and signals got stronger) 5) Asked the KAT1 to tune.. it found 1.6:1 this time. Tested transmitting, and while no one responded, the rig was showing 4 watts out. So, I guess the filters were far enough out of whack to be blocking the signals I wanted. Adjusting them again seemed to do the trick! Thanks to everyone who replied with suggestions (and, the "shadow" one person saw turned out to just be a bit of solder resin).

Perhaps there was nothing connected to that pin on your cable. That sounds like an accident waiting to happen! Ideally Elecraft wouldn't have used a 9 pin D connector, but, as they have, I think I may isolate that pin initially, maybe by not installing L1. Some other thoughts were: - connectorising the signal on the jumper cable; - connectorising L1; - inserting a back to back plug and socket into the D connector to isolate the non-standards lines. It sounds like the other risky signal is the 12V one, but I think the worst that happens is that the filter choke acts as a fuse. It also isn't at risk with normal RS232C signals, only with the ground connection. Is it worth trying to add a PCB mounting fuse?

[Elecraft] Sony MDR headphones
I have the Sony MDR-NC50 noise cancelling headsets. The NC50s completely cover the ears, are quite comfortable for long periods although a little bit of pressure on the ears, but at least they won't fall off if one bends over. I bought these especially for BS7H, Scarborough Reef, because there would be a generator 3-4 feet from the operating table. We're sitting on a rock, remember. The NC50s did a great job eliminating generator noise. I could push the temporary "off" switch and the generator noise would really come through. Because the headsets completely cover your ears, that "off" switch does little good to hear somone talking. You must remove them completely to hear someone talking. I listened with the NC50 while flying in an old 747, San Francisco to Hong Kong (14 hours thank you very much), and the NC50 eliminated that constant drone, making it possible to hear a movie sound track without cranking up excessive volume. At BS7H we also had some Bose noise cancelling headsets. I thought the Bose was a bit better at eliminating generator noise.

I spent a lot of time sailing as R/O in the late 1980s, running between Rotterdam and the USA east coast. 500 KHz was fun. Also spent a lot of time in the Med during that era. There were a kazillion of those tiny coastwise freighters and all of them buzzing, chirping and honking away. Heh.. Ken, I've got Mackay gear but it's more "modern". 3020A receivers out of the MRU-35 console. Even an 8050 transceiver which is still in service on many of the MSC ships. I sailed the USNS Mendonca in 2003 (part of OIF) and we had the 8050 on board.

Re: [Elecraft] DMM question
Thanks Jack, I wasn't sure what was going on but figured it was something to do with RF in room. There's a repeater a mile or two from me and my computer and TV on so maybe that was driving it nuts. I just figured when I was asked to do the AC checks, setting the DMM to mV(actually is was on its autoscaling mode) it would show the <20mV as suggested, but instead it was going crazy. I forced the scale to .000 V and I was able to get a .002 to .000 reading on the pins so I figured I was ok. KX1 is pretty nice to build so far, in fact the KXPD was the hardest thing I've done so far. Now I will tackle the receiver circuits.

[Elecraft] Contest Reflections
Doug, 1. QSK. This is user skill level dependent. If you do 20 wpm or less, the K2 QSK may be fine for you. During contesting, I am going at least 32-34 wpm, and not uncommonly at 40wpm. At these speeds and during a contest, I NEED to hear everything immediately (that is what top-end contesting is about). So not hearing between dits at "slow" contest speeds of 32 wpm is an issue for me. NOTE that I still used the K2 despite that deficit because OVERALL, it is a great radio. But for someone used to real QSK, this is not real QSK. Ask other serious contesters and they will say the same. For most K2 users, who are clearly not serious contesters, this is not an issue at all. Since the K3 says "very much better QSK than the K2," I would easily assume that the deficit is real and acknowledged. *** I would argue that this is not "skill level" dependent, but user preference. Considering the number of Yaesu rigs used by the top ops, QSK isn't an end all issue. If 32 WPM is "slow", I've been in the wrong contests. I listen to some of the folks cranking at over 35WPM and don't see any advantage when you look at the repeat rates. Maybe time is saved with non relevant items or repeatable items like CQ TEST or 5NN, but unless conditions or you have a killer signal, high speed means high repeat rates. 2. Stable power output. *** I've not seen this problem in QRP mode with my K2's either as standalone or with the KPA installed. I have had some issues on 160, but attribute this more to my antennas than the radio. SO IN CONCLUSION The K2 is an awesome value and for all, including serious contesters. At US$600 base, nobody expects it to be 100% perfect for all market niches. This is clearly the ABSOLUTE BEST VALUE going in ham radio. *** There are more than a few "serious" contesters here. Like you, I read the various contest reflectors and I doubt there is a single rig that would define the "ultimate" contesting radio. This is very subjective. It is also dependent on the category you play in, how you operate, what you have for antennas. What one might want for a major HP M/M operation is not the same that a SOSB op would want. Yes, there are basics that everyone wants... a bulletproof receiver comes to mind ;o) Some of us would like to see the HP stations have better Tx performance (better keying shape, stop overdriving their amps). The K2 has exceeded it's design purpose as I see it. As a CW contest rig, I can't think of anything I'd rather have... well except the K3 ;o) Thanks for the Q in WPX!

> The initial production run was upgraded from 200 to 220 and has been > sold out several weeks ago. That run is for July and August delivery. > The second run was also upgraded from 200 to 220 and has been sold out How on earth did you come with these numbers? Did I miss something? From everything I've read (on various lists) I can find nothing to really support this. Obviously the first run was for about 200 rigs, but apart from this all other numbers do not seem to have any foundation. Even on day one (Announcement Day), there was a bit of a conflict about how high the serial number for pre-payers could be: 200 or 220. Seeing as 20 Beta-Test rigs were mentioned, I can imagine that this caused a slight mix up. The first 200 actually sold might easily have the serial numbers 20 to 220. I would guess, and this is off of the top of my head, that the initial run was planned to be higher than 200 (300?) and nonetheless had to be raised due to the response. As to the second run, I have no idea. I would not be surprised if Elecraft has orders for 400 rigs and would be equally unsurprised if the number was 800 rigs. More than 1000 would be amazing.

[Elecraft] K2 - High Current & Low Battery on 20m only
I have K2/100 #3132 with the 160m, SSB, and DSP modules installed. I am also using a KAT100. I have had this set up for a couple of years. The power source is a battery that is being charged as I am operating. My antenna is a Zirpel (like a Carolina Windom). The KAT100 is able to find a match on all bands. On 160m, 80m 40m, 15m, and 10m all is fine (I don't operate that much on 30m, 17m, and 12m). However, on 20m I usually get a "High Cur" warning when I first operate (CW or SSB) on that band. Then it goes away. All seems to be operating OK. Sometimes, a bit later when operating on 20m, I get a "Low Batt" indicator. That too goes away and all seems to still be operating OK. I have a voltmeter attached to the battery and when the K2 gives the "Low Batt" warning, the voltmeter says 13.2 volts. I have not seen any of these symptoms on any other band. I am using a home brewed battery charger that my elmer made and it keeps the battery at 13.6V. The problem typically occurs when operating on 20m after I have turned on the rig. It rarely happens when the rig is a bit warm. So a warm rig and the problem usually does not occur could indicate a bad solder joint? I am not much of an EE so I would appreciate advice on how to track this one down. The Cal Cur is set to 3.7.

[Elecraft] Sony MDR headphones
Hi John, My favorite are Sony MDR-W25G Street Style Stereo Headphones. I use these with the K2. They are comfortable, good sound, don't require a lot of power to drive them, and I can wear them thru a contest weekend. The only negative is that I would like a longer cable on them. They are not noise cancelling, which may or may not be a negative. Oh, and did I mention it... They're cheap! Around $10..

But, it is very important important in at least two areas -- notch (auto and manual) and noise reduction. There is a substantive difference in performance and effectiveness depending on whether these functions are inside the AGC loop at IF or if they're done after the fact at AF.

[Elecraft] QRP SSB Calling Frequencies
In the back of K7SZ's "Low Power Communication" (ARRL publication) is a list of QRP calling frequencies. I am guessing that those for CW are well used, and standardized, but I am curious, as a No-Code General, whether the QRP SSB frequencies are used as often? I realize I am in a minority, but I am curious whether there are any other K2'ers calling/monitoring on these frequencies(?) e.g., 3.985, 7.285, 14.285, 18.130 That said, I am going to learn the code(!), because there is just too much neat stuff going on that I am missing out on.

From my perspective the HPS-1 wasn't really in the running - while it was recommended by quite a few people, I don't need something quite that small and I wanted a power supply that could provide at least 20A continuously. The choice between the other 3 power supplies was more difficult since all three were highly rated in the QST reviews (and an extra thank you to those of you who referred me to the QST reviews). I eventually decided to go with the DM-330MV. While it is more expensive than the SS-25 or SEC1223, the variable voltage feature and front terminals gives me the option of using it as a test bench supply. Hooking it up to my K2, it's very clean on all band from 80m on up. On 160m, there are birdies on the lower half of the band - but the power cable from the supply to my K2 currently runs right next to the coax and ground cables and very near the balun connecting the ladder line to the coax, so repositioning the supply and power wire it should reduce the problem (and the DM-330MV's adjustment to move the birdies works very well, but I'd rather not have to have that additional adjustment)... But the bottom line is that I'm rarely on 160m anyway. Thanks again for all of the advice and information.

Looking at the eham.net reviews, comments on all of the switching supplies seem to range from "great, absolutely no switching noise" to "noise everywhere", and everything in between. Given the sensitivity of the K2's receiver, is power supply switching noise likely to be more of a problem with the K2 than with some other rigs? Are there any switching power supplies that you'd recommend that work well with the K2 (and have little or no switching noise that the K2 would pick up) and are there any that I should definitely avoid?

Re: [Elecraft] K3: elaborate on the DSP at AF
I have noted TONS of references to "DSP" on the FAQ but all of them appear to apply to the DSP at IF. What does the DSP at AF do (capability)? The K3 DSP accepts input at IF. It performs functions at both IF and AF. Bandpass filters, for example, operate at IF and at AF. It would be tedious to list which functions occur at IF and which at AF, and some may change with future firmweare releases. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] DMM question
Chris: A DVM has relatively high input impedance and will pick up stray 60 Hz and other things floating around (AM broadcast, perhaps) when the leads are open. In essence, the leads act like a small dipole receiving antenna. Short the leads together and it should read a lot closer to zero, unless you live next door to a substation or a 50 KW AM broadcast transmitter. (You can think of this as converting the leads to a loop antenna, which has a lot less pickup than a dipole.) Thus, the behavior you see is normal.

I have a radio shack 24-range DMM and when I set it to mV it never seems to go to zero, its constantly counting numbers from 30-100 mV with the leads not connected to anything. If I change the range to .000 V it will show around .020 to .009 with the leads not connected to anything. When I tested U1 pin 1 and U3 pin 6 on my KX1 on the .000 V range I got .000, is this an ok measurement or is my DMM too screwy to use for AC mV measures? All the DC and resistance measurements with it seemed ok. thanks, -Chris Get the Yahoo! toolbar and be alerted to new email wherever you're surfing. http://new.toolbar.yahoo.com/toolbar/features/mail/index.php ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
