[Elecraft] KX1 RX Sensitivity on 20M vs 30M, 40M
i did a lot of measurements due to low sensitivity on 20meter with trackinggenerator and spectrumanalyser the real max peak of the 20meter bandpass filter is at lower frequency (abt 13 MHz) if you align the filter for max gain on 14 Mhz the peak ist abt 6db lower as on 13MHz i did some changes at filter caps but there is a strong influence with the other two filters (40, 30 meter) maybee elecraft has there a new redesign with new filter values - just see with analyser the filter curves.. 73 OE6KYG ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] 40m ECN this past Sunday.
Hello everybody, Kevin, KD5ONS , posted a note saying that I had copied K1EV during the 0200Z 40m ECN last Sunday / Monday. Yes I had under S9 PIGGISH propagation conditions - also W4STK. What Kevin did NOT say , as I think that he is too modest , was that he too was making it over here again - although he was gurgling a bit due to the aurora. And these three gentlemen were about the only stateside people heard here on our CW portion of the band around 0200Z (3 am local) that morning.

[Elecraft] fishing rod blanks
Most fishing tackle stores sell fishing rod blanks for those who build their own rods...Long blanks can be a challenge to transport...Fishing rod ferrules in a wide variety of sizes, and ferrule cement can be bought at these tackle stores and the blank can be cut and ferruled...They also sell surf fisherman's sand spikes which is nothing more than a tube with a point on it that can be pushed down into the sand...The fishing rod is then inserted into the tube..Cabella used to sell fishing rod blanks and rod building supplies...I don't know if they still do...

RE: [Elecraft] fishing rod blanks
Take a look at the Moxon Antenna page for sources of cheap rods. http://campus.murraystate.edu/org/msuarc/moxon/index.htm While slightly more expensive, I bought a crappie (the fish, not the adjective) pole from Cabelas for $10.00. Sand spikes are easily made of PVC. Cut one end at 45 degrees. The other end can be slightly flared by heating on a gas grill and forcing heated over a wine bottle. A protruding stainless steel bolt placed at right angles to the tube can be used as a foot rest to drive the spike in the ground.

Re: [Elecraft] Help figuring out missing part
So I am going to try to pick up a capacitor locally. I am confused by the value. If I understand it correctly, the manual says caps marked with two digits are the value in pf. Three digits markings use the third as a mutliplier. The manual says its either 27 or 271. In this case wouldnt 27 be 27pF and 271 be 270pF? Sorry for the ignorance ! Rich Yes, I would think so too. I don't inventory parts but the one thing I do is take all caps and stick them in foam and get them all sorted. Guess at that point it would be easy to inventory at least the caps. My first K2 had no missing parts. This one was missing an IC on the control board and one extra of another IC. It is possible that the C198 got lost and I wont rule it out :) But, looks like it is gone regardless. If it is nothing special, I will see if I can find one locally. Have SSB, NB, DSP, 160 and 100 watt to build yet. Thanks for the response. 73, Rich - Original Message - From: k4zm [EMAIL PROTECTED] To: Rich McCabe [EMAIL PROTECTED] Sent: Tuesday, August 24, 2004 6:44 AM Subject: Re: [Elecraft] Help figuring out missing part Rich: That is a rare thing to have a part missing in a kit from Elecraft.

I inventory them one bag of parts at a time and dump them into the lid of a shoebox. I sort them in plastic parts boxes and then they are handy when I need them. You might check the envelope that the capacitors came in and see if the 27pf might be in it or it might be mixed up with other caps that look like it. Look at your 270pf capacitors. They mark them 270 for 27pf and 271 for 270pf. They look about the same and it is real easy to confuse them and mix them up. Make sure you have not install the one marked 270 in an place where a 271 should have been used. 73 Jim Younce K4ZM K2 SN: 18 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Hi Everyone, I am trying to repair an Autek WM-1 meter that was hit by lighting. The lighting came through the ground return of the coax.

Re: [Elecraft] Help figuring out missing part
Would think the marking for a 27pF capacitor of 271 in the K2 manual may be an error when compared to the markings for similar values. For example: C43 on the RF board, 33pF is marked 330. The usual notation of this type of capacitors is the first two digits are the first part of the value and the last digit is the number of zeros after this with a 0 (zero) meaning no added zero at the end and a 1 indicating an added zero. However it seems that this rule can be broken when it suits the manufacturer. This highlights the benefit of having a capacitance meter either in a DVM or a LCR meter being invaluable when such questions arise to be sure. As a matter of personal policy I checked the value of all capacitors and resistors before insertion when building my K2. Can save a lot of grief later.

RE: [Elecraft] Help figuring out missing part
There is a mistake on the parts list page of Appendix A, RF Section for C198. You will notice that the caps above and below list 20 (or 200) and 33 (or 330) but somehow C198 is 27 (or 271) - WRONG! Should be 27 (or 270). As I remember, when I built mine it was marked with a 27. Rich, KE0X ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 transmit rapid drift on 10 meters
While tuning up my K2 filters with spectrogram and tuning the bandpass filters, I decided to see how the transmitted CW sounded on my K2 Rev B with keying mod, temperature compensated oscillator mod, and KAT1 tuner, so I drug out my 75S-3B receiver to listen as I tuned up into my dummy load. Everything sounded great on 80, 40, 20, and 15 meters, but on 10 meters, yuk. Not only did the output sound low compared to what I was picking up on 15 meters for instance, but there was a very bad frequency drift on key down that never seemed to stop. I was measuring power output using the detector on the DL1 dummy load and it seemed to be putting out the expected power. I also borrowed an HP8640 signal generator from work to test the receiver sensitivity, since my XG1 seems to be not generating the correct levels. With the HP8640 I was able to test the receiver sensitivity on all bands and found that the receiver is functioning very well, even on 10 meters. Any ideas on why the 10 meter transmit signal is so bad? I suspect that 17 meters may be bad also but don't have a receiver covering that band. There is very little circuitry that is not common to both transmit and receive, so, since the receiver is working properly, it seems like perhaps there may be a parasitic oscillation in the transmitter output stages. However, the ever handy test finger placed on all the circuitry reachable from the top of the RF board made no change to the 10 meter transmitted tone or drift. The bang the sides and top test had no effect either.

Re: [Elecraft] K1 enthusiast wonders ??
Hi Carl, ( everybody else) I too love my K1. (#1337) It has a funny story behind it too. I had just moved into my (Oops, our.) new QTH and to battle the needs of my newfound CW addiction, (Thanks N2EY.) I decided to put a small portable SW rcvr on the nightstand. A dedicated shack was still in the process of being built from a converted closet that was itself converted from a crawl space beneath the stairs. (Anybody laughing yet?) Early one morning I heard HC1HLO from Santo Domingo, Ecuador...a town which I'd visited just a year earlier. There I was with no xmit capability, very frustrating, to say the least! So I decided to check out eBay for a quick and dirty solution. I grabbed a 4-band K1 with all the options for a steal, tossed up a 40m doublet and viola, I was back OTA. I ran the feedline to my father's room downstairs with the intention of eventually letting him use it for his SWLing. Well, it's been about six months and I'm more than halfway toward my WAS, including a very nice contact with Curt, AH6RE on the heels of the Sunday Elecraft 40m net. I bagged a 1,000 mi./Watt award for that. All on 5 Watts! Now I want my WAS to be all QRP, I love it. Yeah, I now have a K2/100 and a Ten-Tec Jupiter in the main shack, but something always draws me to that K1 in dad's room.

K1KID wrote It seems the K1 has fallen off the radar screen here My only HF rig is the K1 and it suits my needs well. I'm lucky if I get a half hour a week for hamming and I'd prefer to spend that time on the air, not in the rig. But eventually something will need fixing or adjusting -- the output seems low; the frequency jumps 30 khz when the knob gets bumped; the RIT mod still isn't working right -- and opening the K1 doesn't seem so overwhelming. As much as I would love a K2 and a KX1, their complexity intimidates me. Maybe it's just perception: That's something I won't know till I find more money and time. My K1 cost me half what the K2 would have when built to suit, and the KX1 wasn't available when I bought the rig. If I was shopping today, the K1's price and 7-band capability would steer my decision straight to it. I use a padded lunch bag or an amazingly well suited cardboard shipping box for transport. My 7Ah gel is great for home operation, but I'd rather have something slimmer for the days I'm portable. Sometimes I take a pack of 8 AA alkalines. I'm not sold on the KBT1. I desire solar.

[Elecraft] K-2 Audio problem
Hello, My K-2 audio sometimes fades completely away. It can happen whether I'm in RX or TX mode. (Yes, the sidetone can fade to faint or no signal.) Sometimes the audio comes back up almost to the original level, sometimes even all the way back. But it fades again before too long. And it happens with an external speaker or headphones, too. This doesn't happen when I've just powered up. In fact, it's probably always more than 15 or 20 minutes but I've never remembered to note the exact time. If the audio stays weak, I can almost always recover it by turning the AF up until the audio makes an odd sound, sort of like a bubble bursting. I may have to rotate the knob to the 3 or 4 o'clock position, and sometimes I go all the way it still doesn't come back. But after it's back, it stays that way for at least a few minutes. The serial number of my K-2 is 9xx (I'm not being discrete or protecting my privacy--I just can't remember don't want to climb the stairs to check on the rig itself ;-) It's a CW-only rig with the I/O, 160M, NB mods. The filter cases were grounded, filters aligned with Spectrogram, several other mods completed last year including installation of the speaker grill cloth (you don't suppose *that's* the problem, maybe the fabric has too tight a weave for the sound to get out??). Well, that probably tips you off to my level of RF sophistication.

[Elecraft] Photo Album of the build of KX1 SN: 821
The enclosed link will take you to an album of the photos I took while building KX1 SN: 18 this past weekend. It might give you an idea of what the insides of a KX1 look like. Note: I always do a complete inventory before stating any kit no matter large or small. http://f1.pg.photos.yahoo.com/ph/jim_you2002/album?.tok=phXAroBBOihzJ6Ir.dir=/cc00.src=ph 73 Jim Younce K4ZM K2 SN: 18 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KD5ONS, ECN and those Pesky KX1's
Kevin, KD5ONS, ECN Guru made the remark in one of his ECN eMail announcments that the 'Pesky' KX1's always seem to get thru when the K1's and K2's can't and there must be an EleCraft secret behind this. T H E R E I S ! It's the fabled RF Hyper Wavefront Accelerator Circuit that has been kept secret for over 60 years. EleCraft uses this circuit in the KX1's final. Discovered during the Manhatten Project of WWII, this RF circuit accelerates RF electrons past the speed of light. Normal wattmeters can only detect 1/100 of the RF as it speeds past. Therefore, when the wattmeter is reading 5 watts, it's actually 500 watts! Small antennas such as Slinky dipoles, HamSticks, Quads(that's another whole subject) have been known to catch on fire or explode as the RF electrons pile up while waiting to radiate. It's still a mystery how EleCraft acquired this circuit as the Dept of Defense requires a 'Burn Before Reading' clearance for access. So, KX1 owners, keep your antennas waxed and fire hoses standing by while checking into the ECN and keep the power down to a couple hundred watts... 73, Art W6KYK1-2 K1-4 (Now, if I can just get my tongue outta my cheek) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

It seems the K1 has fallen off the radar screen here on the Elecraft reflecter and I wonder why. I have a K2 which is wonderful for CW ops in my shack, but it is not as stingy with power as my K1 and too valuable a radio to be bouncing around in the field. Also it is significantly bigger when packing into the wilderness. The KX1 is definately a slick little rig. I have had the opportunity to borrow a friends for a week, and although it definately is a great travelling rig, the K1 outputs twice the power, has 4 bands rather than 3, and seems better able to match whatever you can hook up to for an antenna. I use a Paddelette paddle which mounts to the short K1 tilt stand. Darn near as neat as the KX1 plug in paddle. I have a complete station, the K1, a 10 cell AA battery pack, wire antenna, headphones and logbook all in an insulated soft sided lunch bag. This goes everywhere with me and is without exception THE MOST FUN radio I have ever owned, used or heard tell about! If you don't have a K1, borrow one and you will become a believer too. 73 de Carl, K1KID ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I own a K2 also; but maybe I'm a bit biased because I built the K1 first - I like it better !!! I take it to work with me every day and operate during lunchtime (weather permitting) from the parking lot. I have a padded case with the K1, a 12V 7aH SLA, a solar panel for charging the battery, headphones, key and tools and meter. I have the KAT-1 installed and just love it! It makes using the Hamsticks or hombrewed Buddipole a breeze! I also have a 10 AA battery holder with NiMH AAs that I use when I don't feel like carting the heavier lead acid battery around. I had the K1 internal battery thingie; but took it out. I like the stock speaker better than the smaller one necessary for use with the internal battery. My K1 has 40, 30, 20 and 15 meters installed. I use it just about everyday; and it's a real life saver. There's nothing better than a little lunchtime QRP to burn away stressfull mornings at work! 73 de Larry W2LJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
