There is no positive or negative, there is no polarisation, they can be installed either way 'round and it shouldn't make any difference which way 'round you install them. I installed all of mine in the same orientation as resistors (which are again unpolarised) - so the bands can be read left-to-right, or top-to-bottom. Yes, the extra band (usually gold) is a tolerance, again exactly like the resistors. -- "Nosey" Nick Waterman, G7RZQ, K2 #5209. use Std::Disclaimer;[EMAIL PROTECTED] Computer Science: solving today's problems tomorrow. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Re: Transverter inquiry
I am in the same situation and I just want to make sure that I fully understanding what the solution is: I have a K2 with the K60XV option installed and will use a XV50 for 6m operation. I need to have no more than 10w being produced by the XV50 so I don't fry my 6m brick. I would construct the XV50 and configure it to be driven by a K2 with the K60XV module as per the instructions (1mW drive). Assuming that the XV50 is set to be TRN1, I would set the OUT parameter for TRN1 to .50 (.5 mW) - which would therefore make the max output of the XV50 10w. This would be independent on any setting of the Power control on the K2. I this the correct procedure for limiting to output of the XV50 to 10w based on my equipment configuration? 73 Dennis - WB0WAO EN84ij Iosco County, Michigan K2 #3555 _ Express yourself instantly with MSN Messenger!

Re: [Elecraft] K2 and Kenwood TL-120 linear
Trev, Well, I got the linear working OK, at least on digital modes which are 99% of my QSOs. I'm switching it on and off via the COM1 port and an opto-isolator. The opto-isolator switches the base to collector connection (12K resistor in series) of the switching transistor in the main relay circuit of the TL-120. I could have just grounded the bottom end of the main relay (~40mA current, well within the 4N25 opto-isolator limits), but I reckoned the final solution was the more elegant. K2 minimum drive (~0.1W indicated) gives me 30W from the TL-120 at the ATU. It'll run 50 watts RTTY without the fan coming on.

[Elecraft] Elecraft] DSL filters as RFI filters
There may be several types of DSL filters out there. Each may have a different frequency response characteristic. The original ADSL (Asymmetric Digital Subscriber Network) had a frequency range starting at about 25kHz and ending at about 1.1MHz. The range from 25kHz to 138kHz is the "upstream" and from 138kHz to 1.1MHz is "downstream". The wider bandwidth for the downstream is designed for faster downloading, since most people download more than they upload. Now there are DSL types that extend to 2.2MHz (ADSL2+), 4.4MHz (ADSL2++), 12MHz (VDSL) and as high as 30MHz (VDSL2). There are also variations that may end at some other frequencies between 1.1MHz and 30MHz depending on the local service. The phone frequencies (called "POTS" - Plain Old Telephone Service) range from DC to about 3400Hz. The DC signals include the "ringing" voltage. Signals in the ranges above (voice from DC to 3.4kHz and DSL from 25kHz to up to 30MHz) may be present on the twisted-pair telephone cables from the Central Office to the home (called the "local loop"). 73, John W2XS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Typically, the extra bands can be a tolerance band of silver or gold. 10 per cent for silver and 5 per cent for gold.

Re: [Elecraft] Is a K2 Realignment Advisable
On Feb 13, 2006, at 10:33 AM, Jim Harris wrote: My K2/100 (S/N 4787) is about 10 months old. My question is at what point, or ever, should all the initial alignments be repeated? There are several reasons for asking the question other than electronic components simply drifting a bit with age. Old tube-type rigs required this every year or so, because the heat aged the components. Modern components and equipment are much better and don't get nearly so hot. 1. Recently I've noticed when it is initially turned on the received frequency is about 100 hz high judged by the pitch of people's voices that I know. After 20-30 minutes they drift to near exact frequency. I had this sort of problem before I installed the PLL and BFO stability mods. Your K2 may be recent enough to have come with these modifications. 2. When initially turned on and transmitting right away I've had reports of distortion like I'm crowding the mike. Ditto the above. 3. When doing the initial alignment I had a terrible time with zero beating due to bad hearing. A frequncy counter finally helped solve that to some degree. The K2 is never going to be a precise frequency meter. Due to the nature of the tuning mechanism, it could have an error as large as 30 Hz. I wouldn't sweat a re-calibration unless you find it to be a kHz or two off. 4. I did not use spectrogram as it seemed confusing and my radio seemed to play well enough without it. It is still equal to or better than my IC746Pro. Programs like spectrogram can really help to adjust the filters accurately. I just hate to fix it if it's not broke. But, I'm wondering if I could squeeze a little more performance out of it. I hate to have my K2 on the bench for 2-3 days and not be able to use it. Well, what does everyone say. Go for it or not? Thanks for the help and bandwidth. Wait until you want to make a mod or some other change. Enjoy it in the meantime.

[Elecraft] Receiver actually works!
Just finished Alignment Part II. Found a few more wiring errors in the process and fixed them. Really is sweet to actually listen to 40M. The sound is exceptionally clean. I've been listening to an old Heathkit regenerative receiver to practice code for license exam. Quite a change in quality now with the K2. I am using a multiband dipole, twin lead to balun and RG8U to K2. At first I thought it was too quiet. Then I turned on the PreAmp...still very clean yet seems very sensitive. I almost want to take a break for a while before continuing the kit so I can listen some more (!) I'm sure I'm not done with mistakes yet, but I want everyone to know that If I can do this kit, you can. You've heard of Worked All States, I feel eligible for Replaced All Parts. Broke a two pin connector, lost a few diodes...early in the kit, I soldered every electrolytic cap on the control board backwards,,,the big stripe MUST be plus, right? Yes, I AM an idiot. I'm learning, though. Getting better at desoldering (although I wish I didn't need to). On the Alignment Part II, I just found that I soldered TWO IF transformers incorrectly... used the wrong ones! Of course, I had to break the IF's to remove them...board is OK, though. I did this after rechecking the directions TWICE... strange how you can convince yourself you're correct and miss something like this. I feel very proud to have come this far. Now I can't wait to get on the air. It's only been 30 years. I think Elecraft has an excellent product but the best part is the intangible sense of accomplishment that kit building brings.

I and many others have THOUSANDS of successful CW QSOs using these techniques. Firstly, let's assume you have imperfect propagation conditions: fading, static, whatever. You might miss my call or get it confused if I sent it just once. On 160m and sometimes 80m, perhaps I'll double the call to AA4LR AA4LR. If you only get part of it, you'll send the part you got: 4LR. I'll respond with my full call again: AA4LR AA4LR. The more times we repeat this, the more times I'll repeat my call. Anything else might likely lead to asking you to repeat your callsign, which takes up even more time? The point is, especially in a contest, the vast majority of the time, the first call works. And this protocol works well when there are multiple callers, too. Just a one time sent callsign IS bad operating practice and operating manners. Some of the very best operators I know are contesters, and they ALL do this. It can't possibly be a "bad practice". Contest conditions are usually frantic, crowded and many times plain RUDE. Well, that's true. Such things as sections/states and unique member numbers are exchanged. In the peak of the QRM/QSB I usually always send State and my number TWICE. This is kinda a "QRP" mentality -- "I'm weak and in the noise, I better be redundant." That's not always so. Low power and QRP stations can have formidable and readable signals, given reasonable antennas and fair to good conditions. In some cases, such redundancy may be helpful, like on 160m.

Re: [Elecraft] Is CW a Language? OT
We've been thru this before gentlemen. In a VERY busy contest, there ain't no such thing as "a single frequency" There is signals every 20-50 Hz! The BIG 160 meter contests are examples of this. If you are a "DXer", how many times have you succeeded with only a 'single' call in a big pileup? You may have to send your call a bunch of times,and/or be running a bunch of power. If someone calls me just a single time and I send "QRZ", I expect the other chap to have enough sense to send his call at least 2-3 times. Usually because static is the culprit or two or more callers QRMing each other. Either way you gotta repeat the call. In a contest, the highly abbreviated procedures are commonplace, but I still say it is lazyness or stupidity to apply the same logic to an answer to an everyday CQ call. Whoever isn't familiar with the "protocol", it would behoove him to certainly learn it. What's the problem with that? It's just simple manners, like for example; Like learning not to pass gas loudly in church or on a crowded bus. (to cite a rather crude, but typical situation) If ARRL no longer teaches good operating skills, find out from an old timer, what they are. Sorry for the tirade, but I feel very strongly about this and think it a VERY large mistake that ARRL saw fit to take this section out of the "Handbook". Maybe its because there are more "LIDS" than "A1" operators in Newington now? 73, Sandy W5TVW - Original Message - From: "Bill Coleman" <[EMAIL PROTECTED]> To: "Sandy W5TVW" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; Sent: Tuesday, April 18, 2006 8:56 PM Subject: Re: [Elecraft] Is CW a Language?

Your K2 may be recent enough to have come with these modifications. Bill offers excellent comments and replies. I happened to turn my K2 on early today to check WWV at 10 MHz. Within a minute of turning it on, I was listening to WWV and the dial read 40 Hz high: 1.04. (See below* for my method of finding Zero Beat in SSB mode if you're curious) A half hour later zero beat was exactly at 1.00 kHz I just checked it now, about 11 hours later and it's still at 1.00 kHz I've found that typical since adding the BFO and PLL Reference Oscillator (L.O.) stability mods. It isn't always 10,000.00 kHz, but within 10 or 20 Hz of the right frequency. If you're seeing a 100 Hz shift, I suspect you're missing one or the other of the two oscillator mods - perhaps both. The rigs varied a lot before the changes were made. Ron AC7AC *SSB "Zero Beat": Tune in WWV in either upper or lower sideband mode so it sounds "close" then press/hold CW RV to change instantly to the other sideband. (That button works in SSB as well as CW). If you aren't exactly on frequency, you'll hear the pitch of the tone jump up or down. Tune in 10 Hz steps until you hear the direction of the jump change. For example, when I switch from L to H, I may hear the tone go up in pitch. So I increment the frequency 10 Hz higher, then switch from L to H again. If the pitch goes even higher, I went the wrong way, so I tune 20 Hz lower. Change from L to H again and see if the tone goes up or down. Now it should definitely go down. Tune down another 10 Hz and switch from L to H again. Keep this up until suddenly the tone jumps up instead of down in pitch. That means that I just passed the optimum tuning point. Either zero beat was the last 10 Hz point or it's between 10 Hz points. Note that every time I switch sidebands the SAME direction: L or low to H or high. You can go either way, just make sure you switch back before checking at the next frequency! You don't have to match tones. You only need to be able to tell that the tone shifted direction and whether it went up or down. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Yup. Me too: G5. I only use the PC when I have to write firmware or run hardware modeling software.
