[Elecraft] low tune power with SSB module
Hello, I posted a couple of days ago regarding a strange problem I had with low power output when testing my KPA100. Well I soon discovered that the low power was due to low drive from the K2. Whilst investigating this I removed the SSB to access U10 etc., inserted the links and the cap. Pressed Tune to investigate and my power was back to normal. Re installed the SSB module and Power is down again. The symtoms are that I can get about 2W on 40m rolling of to a 100mW, or so, on 10m. Mike, VP8NO, lent me his spare SSB module and that gives full power on tune. His had firmware 1.07 mine is 1.08. I started checking voltages around my module and discovered that you have to press PTT to get the Tx readings that are listed in the voltage table in the manual (it doesn't specifically tell you that so I thought that Tune would do!). Whilst doing this I discovered that SSB is delivering full power so it is only in tune mode that power is being limited. What exactly does tune do that interacts with the SSB module? I read somewhere, in the archives for this list I think, that tune power may be limited to 2W by some SSB firmware versions. Is that correct? If there is a 2W limit on tune (20W I guess with KPA) what would be causing this 2W to roll off to almost nothing at 10m? Without the SSB module installed I can get good power on all bands. With the SSB module installed and using the whistle test I can get good power on all bands. So it's definitly only the tune mode that is affected. Tune power override, doesn't make any difference. I'm still using a manual ATU and I need a bit more juice to able to get a good indication on my meter! The good news from this is that there is nothing wrong with my KPA100 :-) Cheers Chris VP8BKF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Slug tuned coil installation
Mike, Yes solder the cans, the inductors will not be properly shielded unless the can is connected to ground - it doesn't take that much solder - and yes solder both tabs. 73, Don W3FPR -Original Message- Although, I am not new to kit building, it has been many years since I have built anything. Thus, I have forgotten a few things. Which, brings me to this question, In the installation of slug tuned coils, is it necessary to solder the two(wide) legs which are attached to the can/case of the coil? I am wanting to think that I did this in the past. But, upon looking at the two or three slug tuned coils that I have already installed on the K2's RF board, I do not find that they electrically connect to anything else. Thus, I am wondering if it is really necessary to solder them. Since, it appears that they are just used to hold the coil in place. And, the width of the hole (around said legs) would take bunches of solder to fill. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] low tune power with SSB module
Chris, You may have a problem with CW as well as TUNE. Check voltages at SSB board Q3 during TUNE or keydown on CW. You should have 7.5 to 8 volts on the collector and near 2.4 volts on the base - the emitter should be about 0.2 to 0.3 volts lower than the base. If there is no voltage on the collector, check D5 for proper orientation. Also check capacitor C39 for good soldering and a proper path to P1 pin 7. The path from P1 pin 12 through C42, Q1 and C39 is the route for the BFO signal through the SSB board during CW (or TUNE) operation. 73, Don W3FPR -Original Message- I posted a couple of days ago regarding a strange problem I had with low power output when testing my KPA100.

[Elecraft] Re: T1-K ATU kit and T1-FT817 cable are shipping
I received my T1 yesterday and built it last night. It went together flawlessly and I'm going to love it. I've been wishing I had a small automatic tuner like this and now I have one! A couple comments: Positive - Now that I have the finished tuner in my hand, I can say it exceeded my expectations. I especially wasn't expecting the flashing LED's of the info feature to be easy to read, but they are. Negative - Since the assembly manual is written for builders of all skill levels, there are a lot of details and cautions that an experienced builder may not need to hear. That made construction slower and a little more confusing for me than the less detailed Steve Weber style of instructions, which say something like, These parts go here, and those parts go there. I guess I did have one problem after building it though. I didn't have the rear of the battery all the way down against the bottom of the box when installing it, and accidentally broke the battery retaining tab when I was trying to push it down. It won't be a problem to shim the battery though - especially since I only plan to replace it once a year, when I replace our smoke alarm batteries! Start to finish, the project took about six hours, so I'm going to need to get caught up on some sleep tonight!

Good going, Ken! Can't wait till I'm saying the same about #4834. I've noticed a few notes regarding L31, and I'm not at that point yet in my K2 build.

RE: [Elecraft] L31 10 uH vs 12 uH (was: K2 #4830 IS ALIVE)
Hi Mike: Well, I don't know what the statistics are on the batch of crystals that are being shipped, but I'd give the 10uH a try and see what you get. All you need is 9.8. I had 9.5 and someone else I know had 9.7. However, I'd bet that there are numerous K2s out there that came in = 9.8. So I'd recommend installing what you have. If it doesn't quite make the grade, than you can get a 12 uH from Elecraft. In the meantime, the marginal range should probably work until you get the replacement from Elecraft. It is easy to replace, but don't forget that you'll have to run CAL PLL after you put the new one in and then re-do the CAL FIL after the CAL PLL.

Re: [Elecraft] K1 Question
My K1 was originally with the 4 band card which I configured for 40/30/20/15 meters. Added a 2 band card modified for 160 and 80 meters. The KAT1 tuner works great at 40 meters up but isn't useful on 160 or 80 except and extremely narrow range of impedances. Nevertheless the SWR bridge gives useful information at the two lower bands. 73, Sandy W5TVW - Original Message - From: Ron Polityka [EMAIL PROTECTED] To: .Elecraft elecraft@mailman.qth.net Sent: Wednesday, March 23, 2005 8:22 PM Subject: [Elecraft] K1 Question | Hello, | | I was wondering if anyone on the list has tried this with their K1 and the | ATU installed. | | Have the 2 band board made for 80 17 meters and the 4 band board made for | 40, 30, 20 15 meters.

[Elecraft] sometimes, it's good to see smoke!
Let's say you've been trekking through deep snow at a high elevation, cold and tired. Hungry, too. You're heading for a hut, not sure you're on the right trail. Then, suddenly - there it is! And, coming out of the stovepipe - smoke! Good smoke. Or you arrive at the annual picnic, to find all your friends, a freshly tapped keg of Fuller's ESB...and the delicious aroma of a hawg slowly cooking in the smoker, which is emitting clouds of fragrant, good smoke. But...lets pretend you're building a K2, and it's time for Alignment and Test, Part I...smoke is about the last thing you'd want to see, right? Well, there I was, last night, about to do that very thing. I pushed the button, and - no smoke. This was a wonderful thing! And such a pretty display! As the relays sang their clicking song of welcome, I thought: I'm gonna love this rig, but it'll be tough to say goodbye to building it. LL/K3ESE __ Do you Yahoo!? Yahoo!

Re: [Elecraft] K1 Question
Ron Polityka asked: Have the 2 band board made for 80 17 meters and the 4 band board made for 40, 30, 20 15 meters. Then swap them out in the field. Hi Ron, I have exactly the two filter board combinations that you mention. It's no real trouble to swap out filter boards, even with the antenna tuner installed. The standoffs *would be* the greatest aggravation, but you can fix that with a technique suggested by Tom / N0SS years ago: Capture the two KAT1 PCB standoffs on their screws with a bit of thin rubber band material. Run it through the stand off before screwing the screw through the standoff, then trim off excess at each end. It works wonderfully. The only aggravating part remaining is replacing the short screw that holds down the middle section of the filter board. It might be worth leaving its lock washer off to simplify things. If you have the KBT1 battery installed, it can be difficult to get a firm grip on the filter board to be removed because the KBT1 fits against the front edge on the filter board. I no longer use the KBT1. A very leisurely pace will allow board swaps in well less than 10 minutes. My biggest qualms abut swapping boards in the wear and tear on the connectors and nearby PCB traces, and protecting the un-installed filter board from damage. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Several times over the last couple of months during the building of first my K1 (#1949) and then my KX1 ( #1056). I was intimidated by the instructions in the manuals. First with the K1 and KAT1 that I finally got the nerve to finish and install it today. The KX1 did a number on me too when I read the manuals from a PDF down load before ordering. I finally took the plunge and ordered it, built it in less than twenty hours, then ordered the 30m mod. built and installed it earlier this week before I tackled installing the KAT1 today. The manuals for both radios are so beautifully written that construction of the K1 KX1 is extremely easy. Wayne and Eric along with everyone at Elecraft are to be commended on a job very well done.

If I have no replies to my CQ's I will jump to 20 meters and then 40 meters. At 20:30 UTC I will be following the schedule that is posted on Ed's web page. http://www.wa3wsj.com/files/PolarBear2005.html Hope to work a lot of QRP'ers from the AT. My QSO count is at 420 from the Appalachian Trail. Would be great to hit the 500 QSO mark tomorrow but I am not counting on it. So if I have already talked to you before from the AT and you hear me please stop by on the air and say hello. We will keep it brief so I can work as many stations as possible. It has been 5 years now since I have been going to the AT with my radios. I have not missed one month since March 2000.

Once installed, the KAT2 loaded my flag pole (I use it as a rx antenna sometimes) just fine -- relays chattered for maybe 4 sec, made one QSO on 30m, flag flapping and all. Apparently 11.7V on the rest of the devices didn't kill them. ALL: In the process of installation, I found two unsoldered connections in my K2 which was the first Elecraft thingy I built. It's been working fine, but, after the new V-reg was installed in the KAT2, the tuner was still dead. I am a turtle, and I count and check off every pin to be soldered, and then check it off again when I have soldered it. Both of these were obvious if you were looking at them. So much for the Turtle Technique. 73, Fred K6DGW Auburn CA CM98lw ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] T1 Arrives--Good News and Bad NewsQ
First the good news! My T1 arrived today! Now the bad news! I have a new Bullmastiff puppy--3 months old--his name is Linus, but I may rename him T1--I had the bags out of the box to inventory parts--got a phone call--puppy (he's 30 lbs. already), stretches up to table and grabs bag of parts--takes them out on the patio--proceeds to chew the bag to bits! Parts all over the patio! I recovered most of the parts (I think), but now an inventory is crucial! I wonder what the calorie count is for radio parts! Any bets on whether I found ALL the parts Dave W7AQK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] KAT2
Fred, Great that you had success with just the replacement of the voltage regulator. FB on the perormance of the KAT2 - yes it will load just about any hunk of wire - its only weakness is in attempting to load very high imedances such as an end fed half wave antenna. Keep that flag flapping. BTW, I am not hard to find - try a Google search on 'W3FPR' and you will find plenty of references. Fortunately a search on my name will reveal very little - good for the current state of affairs with the spam generating folks - I get more than I want as it is. On teh missed solder joints - take comfort in knowing that you are not alone - unsoldered or poorly soldered connections are the majority of the problems that builders encounter. Even I miss a few at times, but when I do, I usually do it big time - like failing to solder an entire IC - yes, I solder in groups - big groups - I try to insert all the components on one manual page before I solder things. Soldering through the 'forest of wires' is a nuisance, but is easier for me in the long run. I hold to the rule that I never clip an unsoldered connection - and that is my only salvation - but then I have been doing this Elecraft stuff for over 5 years now - if you are just starting 'don't try this at home'! 73, Don W3FPR -Original Message- This is primarily for Don, whose address I don't have, but read on.

[Elecraft] Help Identify a Balun
I was given two baluns, but I have no information about them. They are marked Ultra-Bal 2000 Model UV-1. Can anyone tell me what kind of baluns these are? I plan to order the parts for a new horizontal loop antenna on Monday. I need a balun to transition from open line to coaxial cable. If the balun I have will work I can scratch a new one off my shopping list. Thanks for the help.

[Elecraft] Egad!! A Missing Capacitor
Hi All, I was working on the RF board of K2 4777 and found that capacitor C225 was missing. A 390 pf, NPO type. I sent in a request for the missing part a few minutes ago. If any of you have had missing parts, how long does it normally take for Elecraft to get one shipped off to you?

[Elecraft] K2 S/N 4786 doing well for first 24 hours!
Well, I'm not sure if the bands are just doing really well today or if it is the new K2. I don't really operate much, or at least I hadn't in the recent past, however that may all be changing now that the K2 is in my life. Since I hadn't used the big rig for quite a while I don't know how it compares really. I have had 8 QSOs in the past 24 hours on 20, 30 and 40m so far. Okay, yeah, big deal, most of you probably do more than that, right? For my operating, that is a lot though (except for when I'm in contest mode). I guess it helped that I was a bachelor for tonight. More impressive, though, was what some of the QSOs were. I worked a station on 30m in Hungary, my first DX with the K2! I got about as good a signal report as he gave other people who had called him, but then I was running nearly QRO at a full 5W output. Wait, it gets better! I did work a few other stations on 20m and 40m. Then later at night I heard the FT5 DXpedition on 40m but didn't feel like trying to bust that pileup since I am not so confident with the rig yet and since I haven't done any CW DX pileup busting in probably 15 to 20 years. But it was fun to be able to hear the FT5 station! I then worked a station in Hungary on 40m and he gave me a 579 before he knew I was only running 5W. I had heard him working a station in Panama, and heard the Panama station sign off. I wasn't sure whose frequency it was so I just dropped my callsign in there to see which one would come back. I'd have been happy either way. Then I worked a station in OR who was just above the noise (the Hungarian station was actually stronger), but it was fun trying to pull him out. As soon as I got done working him another station came back and said QRZ QRP? de W3AS Well, I live in Allentown, PA and as strong as this guy was I figured he was quite local as well. Turned out he was near Spokane, WA and running 80W to a 2 element yagi (again, this is on 40m) up 80 feet. No wonder he was so strong! He later lowered his power to 5W and I could still hear him fine, at which point I lowered mine to 1/2 watt and he could still here me okay too! With that, I'm off to bed and will pack up the K2 for tomorrow to operate from Pulpit Rock along the Appalachian Trail with the EPA QRP Club. I'm scheduled to operate on SSB mostly so I'll use my FT-100 for that but when I can operate CW I'll switch over to the K2. 72/73, Mark, NK8Q K2 #4786 Polar Bear #4 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 Pre Filter
Hi Benny, On the face of it your suggestion makes sense, for a little signal attenuation get back the lost IMD performance. Is it as simple as that ? I have copied this to the reflector, so that others more knowledgeable about IMD than I might comment. 73 Stewart G3RXQ On Thu, 24 Mar 2005 23:11:20 +0200, Benny Aumala wrote: Stewart, something KISS came across when playing with the prefilter idea and simulator. Voltage response, input impedance and return loss were in my interest for close and large-band frequencies. Put a 1,2 - 1,6k resistor across the filter input (between step-up and first fiter). Or place 200 ohm across input of step-up. This gives good large band termination for post-mixer amp and drops the signal 1 - 2dB instead of 5dB with resistive attenuator. Then only part of pre-filter loss comes into play, and you can enjoy the good IMD. What say?
