Re: [Elecraft] FD Battery rules (was QRP Power Level?)
Just a clarification. While the Battery subclass is limited to 5W, the Alternative Power Bonus is not. We were running 100W on Battery for one of our stations using Solar Panels as the power source. I also agree that the Battery subclass should allow more power. There would still be the QRP power multiplier to account for the power level. My club might be willing to go to all battery, but would not be willing to give up 13db. I'm for recognizing the additional effort to do an all battery FD with the Battery subclass. I don't think we should then penalize them by restricting the power they can use. The effort required for Battery is strongly related to the power level. If an organization wants to go to the additional effort to run 100W on battery for Field Day, they should be allowed to so so. Just have them get the normal multiplier for the level they run. -- Clark B. Wierda N8CBW

I think there are a couple different issues here. First off, the power levels aren't equally spaced. 5 W to 150 W is almost 15 dB, but 150 W to 1500 W is only 10 dB. Second, a multitransmitter setup has to use the power of the highest-power station in the setup. IOW, if it's not all QRP, it's not QRP at all. It didn't used to be that way - until 1971, a multitransmitter setup could have multiple power categories and multipliers. I think we should go back to the way it was before 1971. 73 de Jim, N2EY

[Elecraft] KX1 Nearly Deaf
Gentlemen, I had a similar experience with my KX1. I could hear signals fine when aligning and the screwdriver was touching the trimcap, but very little as soon as I pulled it off. I didn't have desoldering equipment available and knew that I had tried to do some adjusting to my L1 so that was suspect. When I was finally able to purchase a desolderer, the first thing I did was rework the L1 connections. It has been fine ever since. It was perplexing for a while: I didn't know if the problem was the receiver, the new antenna, or just that there were no stations on the air here. 20M is populated here, but sparsely. Most of what I hear is European. I have heard one VA3 call. I've heard Finland and Sweden both pretty well. Nobody seems to hear me at all. I'm working on locating a higher antenna site hoping to reach out better. I'm fairly limited to 12' tents (no trees). Radials and poles are out of the question due to a need for secrecy. CPT Drew Neve - 9K2/KB9LLO Battle Captain S3 ASG-Kuwait Eager to Assist Hi folks, I have resolved the signals getting loud when I touch the board mystery with help, but there is still something amiss. Upon further testing, the receiver appears to be profoundly deaf. It does hear some signals on 40, and even some on 20, but not nearly as well as it should. However, I have some clues here. Attaching the antenna does affect the signal level, so the receiver is, to some degree at least, seeing the antenna. Also, the receiver is detecting signals and is on frequency. It hears my signal source OK, and even the few strong external signals are perceptible, but again not nearly as strong as on other receivers here. Another point of note, the background hiss really doesn't sound like what I would expect. No static crashes, not the background noise I would expect. Just a dull hiss like you would hear when raising the volume on a PA system with no input. Another point, although seemingly unrelated, is the AF gain control gives me basically no audio until I get to about 3 o'clock. Then it gets loud very quickly. (This could be a combination of not very sensitive headphones and the audio taper characteristics of the pot, if in fact it is an audio taper.). And then just before it hits maximum clockwise position, I hear a slight pop and it gets noticeably louder.

RE: [Elecraft] KX1 Nearly Deaf
I appreciate your input, CPT Neve. My problem may be different though. I solved the mystery of the signal getting louder when I touch it via a combination of using a completely non-ferrous adjustment wand and the realization that when I used my K1-4 into a dummy load in the shack, I was coupling a much larger amount of RF to the KX1 via capacitive coupling through yours truly. L1 probably (?) is not the issue as I get a 0.0 ohm reading from the center pin of the antenna jack to the schematic point B, which of course passes through L1 and L2. I am going to begin some dynamic testing via crystal oscillator and an RF probe as soon as I can find the parts I need for the oscillator. I was going to use my XG1, but Don W3FPR (who has been helping me along here), informs me that it doesn't have enough output, so I am going to build the one from the K2 manual. Thanks so much for taking the time to offer your experience, it is always welcome and appreciated. You take care of yourself.

RE: [Elecraft] ATU K2 Question
The KAT100 uses a cable to connect it to the K2, and that cable plugs into either the KPA100 AUX I/O or the AUX I/O connector in the QRP lid.

RE: [Elecraft] ATU K2 Question
John, There is an alternative to the KIO2. The KAT100 uses only a few control signals from the K2 and doesn't use the RS-232 interface. You can easily and inexpensively build a replacement for the control portion of the KIO2. Look at the circuit diagram for the KIO2 and for the KAT100 and the wiring of the cable between them. Only the ground and pins 6,7,8 and 9 are used (and one of those isn't needed, but I don't have the circuit diagram in front of me to look at right now). I ordered the plug that goes into the control board and the 15 mh inductors from Elecraft, and found everything else that I needed at my local RadioShack (the rear panel connector, a cable connector, a few capacitors and a small circuit board - the 2nd cable connector and the cable wire itself comes with the KAT100). If you want, I can send to the circuit diagram and layout of the 2 little circuit boards. One of the web pages that has information about building the KPA100 and KAT100 into a single EC2 cabinet has a section on using the KAT100 without the KIO2. I started with that, but found that the circuit diagram didn't quite agree with the Elecraft schematics or the cable wiring. Eventually I plan to add a KPA100, but probably not for a quite while and I didn't want to have to purchase the KIO2 when I would get one with the KPA100. 73, Bob W1SRB -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Don Wilhelm Sent: Friday, July 07, 2006 9:30 AM To: John Bahun; Elecraft@mailman.qth.net Subject: RE: [Elecraft] ATU K2 Question The KAT100 uses a cable to connect it to the K2, and that cable plugs into either the KPA100 AUX I/O or the AUX I/O connector in the QRP lid.

[Elecraft] Anyone compare K2 RX with a classic rig?
Hi folks, Lately, I've been on the hunt for a 2nd receiver just for fun. I'm looking for Drake R-4B. During this time, I've been wondering if I'll want to put a full B-Line on the air or will just have an R-4B as a backup RX. The answer to that depends largely on how the R-4B (or A if that's what I end up with) sounds performs compared to the K2. I continue to be impressed with the K2 receiver. I'm wondering how it compares to the R-4* receivers or any other non-DSP boat anchor classic receiver from years gone by. I've already compared it to an Omni V and IC-735 and the K2 was better than either. We won't even talk about how much better the K2's RX is than the Century 21 or Century 22 :-) I had a very mint TS-830s but not at the same time as the K2 so I didn't get a chance to compare them. K2 vs. Drake R-4B; there are several things we know going in. K2 uses xtal filtering in the IF. R-4(A,B) use LC. K2 is single conversion, R-4* is triple. This suggests to me that the K2 will have better rejection of off freq signals and a better S/N ratio. Actual results are TBD. I'm sure at least one of you has a classic Drake or Collins rig that you've had a chance to compare to the K2.

RE: [Elecraft] QRP Power Level?
Kent, There is no 'official' concensus that I am aware of. Each contest should specify what they consider QRP power levels in their contest rules. CW is almost always 5 watts, but SSB is sometimes either 5 watts or 10 watts - the ARRL seems to consider 5 watts as QRP for both SSB and CW. Check the rules for each contest (or certificate) to be certain. 73, Don W3FPR -Original Message- Can someone tell me the official definition of QRP Power Level? Is it 5 watts for voice and CW modes?

However, it can't compare with the K2 for receiver dynamics. Unless it has the Sherwood Engr. front end mods. More important to me is the QSK with the K2. The R4C used vox for keying. In my opinion, the greatest advantage to modern rigs is the QSK keying. Its like turning the lights on in a dark room. And as far as dynamic range goes, not only does the K2 have all the boat anchors beat, but I think the K1 does also. Recently, QST reviewed an old Collins and found an IMD dynamic range in the low 70's. The K1 is about 20 db better. However, you will enjoy using the Drake. Besides an ergo layout and real knobs, it has proper passband tuning (at the expense of several stages of conversion) and an analog S meter.

Since this in an Elecraft list let's see what the Elecraft QSO Party rules have to say about QRP power levels... When using QRP calling frequencies, use QRP power (5W or less for CW/Digital, 10W PEP or less for SSB) When in doubt always ask the sponsor of the contest for a clarification on what they consider QRP power on SSB (before the contest begins) so you can operate the maximum power allowed for that mode. If the rules say that 10W PEP on SSB is QRP...you can bet the house that the guys you are going to compete against are going to be running 10W on SSB even if they normally define SSB QRP as 5W. 73 de Tom K2TA - Original Message - From: Bob Tellefsen [EMAIL PROTECTED] To: Kent Tannery [EMAIL PROTECTED]; Elecraft@mailman.qth.net Sent: Friday, July 07, 2006 7:36 PM Subject: Re: [Elecraft] QRP Power Level?

Tom's email can be read to imply that ARRL Sweepstakes defines QRP on SSB as other than five watts. The rule specifically states: 4.2.1. Q for Single Op QRP (5 Watts output or less); Thus for SSB or CW, the max is 5 watts. He is right about contest rules - be sure to thoroughly read a contest's rules before operating in the contest.

Re: [Elecraft] QRP Power Level?
This is a bit of a bête noir for me. QRP-ARCI, QRP Canada, and GQRP all define SSB QRP as 10W. The K2, Elecraft's only QRP SSB rig, is spec'd at 10W (though the K2 can do more on some bands), and while the K1 could be modifid to run SSB, Elecraft isn't doing it because of the insufficient power output. I think that states Elecraft's position on the topic. As for FD, I wish the ARRL would follow suit, and also decouple the battery/solar bonus from the 5W limit. If FD really is a disaster test, it is more reasonable to have a category that is one-op, solar/battery power, and not limited to 5W. My father N5LK was in Katrina, and we were both in 2 other major hurricanes (Camille and Betsy) and a tornado, and I was in the 1989 Loma Prieta 7.0 earthquake, and am expecting another one sometime. I am prepared to run welfare traffic with solar power and batteries, and while I will not be running 100W, I will not be running 5W either.

Each contest should specify what they consider QRP power levels in their contest rules. CW is almost always 5 watts, but SSB is sometimes either 5 watts or 10 watts - the ARRL seems to consider 5 watts as QRP for both SSB and CW. Check the rules for each contest (or certificate) to be certain. 73, Don W3FPR -Original Message- Can someone tell me the official definition of QRP Power Level? Is it 5 watts for voice and CW modes?

[Elecraft] FS: K2, KAT-100, and new firmware
I am would like to sell this as a package. I bought this through this list two months ago. The seller listed it as follows: QUOTE FOR SALE: K2 # 185 and KAT100, preferably together but I'm flexible. My K2 has given me several years of great, dependable service but it's time to free up some assets to try other avenues. My K2 has never been abused in any way (such as extreme SWR, over voltage, rain, etc.), and I don't smoke. It's had all the important Elecraft-recommended performance mods and Alerts applied, including the A to B upgrade. It has the KAF2 audio filter/real-time clock, KAT2 internal ATU, and KSB2 SSB modules installed and KBT2 internal battery kit (everything but the battery - it's old and you don't want it). Although not installed, I'm including the FWK2MCUIO set (main IC version 2.04P and IOC version 1.09) and FW SSB (version 1.08B) which will make the rig ready for the K2-100 and 60-meter conversions. The KAT100 is FULLY ASSEMBLED BUT UNTESTED - I just never got around to buying the K2-100 amp kit to finish testing. Included are original manuals (including accessory manuals) for each, and power cables with Anderson Power Pole connectors. Lots of pictures are available at http://home.comcast.net/~slackfan/. Email me with any questions. UNQUOTE PLEASE NOTE: The K2 does an excellent job on CW. The a recent contest I worked PS2T on 5 watts / 20 meters, which just makes the 1,000mile/watt level. The SSB power out is minimal. I tried using three mikes (and changed mike pin jumpers). The SSB board is Rev. C and Firmware is 2.01H and IOC 1.02. There is no reading on the S-meter when I transmit, and no reading on ALC. I do get a very weak signal when I used each of the three mikes and listened on my other rig. I also transmitted PSK and again get a weak signal, however, the IMD was -23. A couple of hams within 5 miles said they heard me on 20 meter SSB, but just at the noise level. Another ham who lives about 10 miles away could not hear me, but I heard him calling me. The K2, accessories and upgrades parts are over $1,000 today. I will sell the entire combo for $800, including continental US shipping (This is the same price as I paid). Shipment will be to the address on QRZ. Payment needs to be made via certified check or money order as I do not have PayPal at this time.

[Elecraft] K2 led diffuser
I'm building K2 # 3612 . Question about the led diffuser. The back side has a thick foil. The front side is much more thinner, a milky thin foil which is a bit loose from the glass. Is it right to leave the thin foil on there, or should it be taken off. I'm not sure.

RE: [Elecraft] K2 led diffuser
Hello Arie My K2 was a few serial numbers before yours. The layers in my kit were: The LCD: Polarizer (remove this and it is ruined) Glass Liquid Crystal stuff Glass substrate with lots of pins Transflective Layer (looks a bit like metal foil - don't mess with it) The Back Light: Thin milky film half stuck to clear plastic diffuser, kind of wrinkled Clear plastic diffuser with LEDs stuck to it Thick white material (not attached well, but it is important to leave it on there) I tried to straighten out the milky film but it only got worse, so I decided to leave it off. My guess is that it might help even out the light if you leave it on, but I didn't want to look at the wrinkles forever. I figure it was in there to prevent scratches - but I could be wrong. I wonder how many encountered this? Michael, AB9GV I'm building K2 # 3612 . Question about the led diffuser. The back side has a thick foil.

It was a bit hard to tell and I inadvertently removed the polarizer (I'm sure I'm not the only one). I ordered another but stuck it back on so I could continue until the new one arrived. The old one is still working fine 3+ years later, but I have a spare if I ever need it. 73 - Bob, N7XY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Anyone compare K2 RX with a classic rig?
I have an R-4A which is about the same as the R-4B in most respects. I would say that the performance is very good, but not as good as the K2 in several areas. (I also had the original R-4, and it is also about the same in performance. The differences between the R-4, A, and B are the number of tubes vs. transistors, and the location of the AF gain control). The L/C filters are not as good as the xtal filter in a crowded band. For rag-chewing, they are fine. But in a contest with a lot of very strong signals around, the R-4 doesn't hold up well. It may be due to the skirt selectivity of the L/C being wider than the xtal filters. The older R-4 has some detectable hum in it. This is very noticeable with very sensitive headphones. I use an external passive audio filter which helps quite a bit. But there is always a little there. (I may also need to replace all of the electrolytics in my particular receiver). Then there is the size, the heat generated, the power consumed, the need for an external speaker, the eventual maintenance required, etc. I use the R-4A with the T-4X transmitter, and the combination is a joy to use for CW rag chewing. The R-4 has great AVC action, and so full QSK is possible with an external t/r switch. The sound of the CW coming from the T-4X is very nice. Together they make a nice combination, even though there are 23 tubes total glowing on the dark when they are both on. The old twins are stable, and they sure look good sitting on the desk. The first rig that I turn on when I come into the shack is the K2. If I need more power, I use a Kenwood TS-930S. If I am going to rag chew for a while, I use the Drake twins. It is nice to have the different rigs, and they all have their good points, but if I had to keep only one, it would be the K2. 73, John W2XS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 RF Board Assembly Part 1 Question
The K2 assembly of the Control Board and Front Panel Board went perfectly. But my luck has apparently run out after starting the RF Board Assembly Part 1. I finished installing the latching relays but I am unable to find the resistors required for Part 1. The resistor tape starts with the values listed in Part 2. So I have the large resistor tape with 88 resistors on it. Are the resistors for Part 1 Assembly on their own tape? Or are they supposed to be loose in one of the parts bags? Somewhere along the line I appear to have come up short the 9 resistors needed for Part 1. Everything else in the inventory appears to be ok.

RE: [Elecraft] K2 RF Board Assembly Part 1 Question
Frank, I just check the resistor strip from K2 SN 5428 which I am building for another ham. There are normally 95 resistors on the strip. The first two resistors are 220 ohms, and there are 9 resistors from the strip that are to be used in the Part I assembly. Of the 86 resistors that should remain after Part I, the first three values are 100k, 100k and 470 ohms. 88 resistors in the strip does not break exactly between Assembly Part I and Part II, so you may want to check the sequence a bit further to be certain you have the correct strip (if 10 values in sequence are correct, it is most likely the correct strip but with a few missing on one end. If you find your strip short (or incorrect) after an additional count, I am certain an email to [EMAIL PROTECTED] will bring you the missing resistors. 73, Don W3FPR -Original Message- The K2 assembly of the Control Board and Front Panel Board went perfectly.

Re: [Elecraft] QRP Power Level?
actually, the two major international QRP groups, QRP ARCI and GQRP use 10 watts for SSB, and 5 watts for CW, since they are equivalent in talk power. It is the ARRL who is the odd man out, as most local QRP clubs follow QRP ARCI in North America, and G-QRP in the rest of the world!
