[Elecraft] Bad crystal filter ?
Working with my newly constructed K3S today, I noticed that receiving through the FL4 crystal filter (400 hz, 8-pole) was noticeably suppressed. Through the FL3 (1.8 kHz) filter, an RTTY signal would be nice and strong with good S-meter indications. Going to 400 Hz the signal would nearly be lost and I could not decode it. Going to FL5 (250 Hz), the S-meter would pick up again with strong signals. There's not much to check on the Config menu except the FL4 GN and it's at max (8 db) - not much change. Is there something else I should do to deal with this ? 73, Jamie WB4YDL Sent from my iPad __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Bad crystal filter ?
In response to W4TV Joe's question: The frequency offset for the 8-pole crystal filter is 0.00 Hz. The Pitch is 650 Hz on the K3S. And the Mark for RTTY is the standard 2125 Hz. I've got a new 400 Hz filter on its way so I'll see what the problem is. I just hope it's not an RF board. I took ESD precautions very seriously while building it so, fingers crossed. 73, Jamie WB4YDL Sent from my iPad > On Sep 18, 2015, at 2:30 PM, James C.

[Elecraft] Controlled envelope SSB
I found a most recent article in QEX on controlled envelope SSB most interesting in that it could yield close to 3dB in power by eliminating the overshoots in filters, etc. I know contesters are always looking for the next 3dB they could attain and certainly this could help DX'ers and ragchewer's alike. It said in the article that Flex Radio has already started to experiment and program their radios for this. I was just wondering if this was a possibility for the K3 ? 73, Jamie WB4YDL Sent from my iPad __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
[Elecraft] P3 problem - was Problem retrieving FW
Thanks to Dick for pointing me to manual FW loading. This worked very well and I now have both my K3 and P3's FW updated. The reason I felt this was necessary: Our Field Day was one typhoon after another with multiple heavy downpours and thunder/lightning. Through multiple shutdowns, our FD team faced this adversity well and we made the best of it - and had fun. We did however sustain some minor damage thought to be due to lightning bursts. Our digital station consists of my K3 / P3 with TXBPF filters, LDG 200 tuner, and an early model MH Microkeyer. The pre-FD checks were perfect. However, just before tee-time, when we turned everything on, we noticed that the computer was not seeing audio and the P3 showed no signal activity even though the radio was fine and signals were multiple. Despite all attempts, we were left with trying a FW update. I took the K3 / P3 home and did this. However, the P3 still does not see signals. I put my signal generator on the K3 at 50 uV and still no signal seen. Taking just the K3 back to the FD site, I hooked things up without the P3, hoping the audio issue would be corrected. No dice. The Microkeyer appears to be damaged as well. The audio was redirected directly from the computer to the radio, bypassing the Microkeyer, and that worked fine. Bottom line is I need to get my P3 fixed and maybe I can get an out-of-production Microkeyer fixed as well. Ideas ? 73, Jamie WB4YDL Sent from my iPad __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

I won't be using the output of this decoder for antenna switching - just band following with the BPF's. I'll be utilizing an older Microkeyer for digital operations and this uses the AUX I/O for FSK and PTT. Looking back in the archives, I presume I will need a DB15 Y-cable which I see Elecraft sells and I presume ABCD on the TXBPF 5-pin DIN is the same as 0123 on the AUX I/O DB-15. I just need to make up this interface cable. One other thing - my K3 is serial number 616, so I have the KIO3 board without the pull up resistors. This is more specific to the TXBPF, but does this unit need those resistors; that is, do I need the upgraded KIO3 board ? 73, Jamie WB4YDL Sent from my iPad __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] ERR 12V
Hello: I was working the NAQP today on 10M and was doing fine and then the PA got bypassed and I got ERR 12V on the screen and to check the circuit breaker. Well the circuit breaker is not popped. Turning the radio on and off did nothing and I'm forced to run QRP - well, SP. Changing bands also did nothing to rectify the situation. The antennas are resonant with good SWR.

[Elecraft] K2 - starts in transmit mode
Hello: I hadn't started up my K2/100 in awhile and I wanted to give it some exercise today. When I hit the power button, I was surprised to see it in transmit mode with a hum/tone coming from the speaker. I immediately shut it down, disconnected everything and hooked up a battery and a dummy load and set the power to minimum. Pushing the power button revealed the same symptoms - increasing the power showed the LED power meter increasing in power until it got close to 100 watts and then showed Hi Cur. I powered down and then shut it off. I don't know what to try next, that is before attempting to do a MCU reset.

[Elecraft] 6M problem - resolved
Hello All: Just a note to update you on my K3 problem with 6M. It turned out that the 8.215MHz trap on the KAT3 board got fried during FD. Gary came to the rescue and I got the new parts today and installed them no problem. After tuning the trap, I was able to get 1:1 SWR with the dummy load connected on all bands. It's now back in service and looking good !

Re: [Elecraft] K3 6M problem
Hi Rich: Yes, my problem is that I have terrible SWR when the ATU is in BYPASS and the antenna is a known resonant load. I also tried to tune into a DL and DID get a 1:1 SWR, but when returning to the antenna with the ATU in BYPASS, the SWR was around 8:1. I'll be opening up the K3 to inspect the L10/C10 area on KAT3. That appears to be the problem area. Gary has sent me an email stating they now have different parts for that area.

I had the problem of a high SWR on 6 Meters when the ATU tried to find a match on my 6M yagi with a known relatively good 1.2:1 SWR. In the BYPASS mode the SWR looked fine. Using the ATU produced a much higher SWR on 50 MHz. If your K3 internal SWR display indicates a good SWR in the BYPASS mode, but the ATU cannot find a good match, there is a fix. I received a BETA firmware update along with suggested parameter changes of some of the hidden MENU settings (need to turn TECH MD on) which addressed the 6M ATU problem. The ATU in my K3 now performs as it should on 6 Meters. Local friend K2PI also had the same problem which was resolved with the BETA firmware update. If your 6M SWR is good in the ATU BYPASS mode, drop Elecraft tech support a note. 73, Rich - K1HTV = = = -Original Message- From: James C.

Re: [Elecraft] K3 6M problem
The weird part about this is that it hears great on 6M ! If the SWR was truly high, I shouldn't be able to hear squat. Engaging the PR6 preamp does its usual thing, increases signal (and noise a bit). It's like the SWR meter is just deciding to indicate high when it's not - and of course the output power is folded back. 73, Jamie WB4YDL -Original Message- From: Ron D'Eau Claire [mailto:r...@cobi.biz] Sent: Friday, July 01, 2011 12:05 PM To: 'James C.

Re: [Elecraft] K3 6M problem
OK, more data points. Since I was getting good SWR at the mW level with the analyzer, I cranked the power down to 1 watt and pressed tune. Got good SWR and 1 watt out. OK gently walked the power up and tried again. At 1.9 watts, I would get good SWR for a second and then it indicated 8.9:1 SWR. I went out and bypassed the ICE suppressor and that made no difference. The only other radio I have that operates on 6M is my IC-706 - um, mobile. So I jerked it out of the truck and rigged it up in the shack and ran an SWR graph - less than 1.3:1 all the way. OK, so I hear FG5GP on 50.130 MHz and give him a call with 100 watts - no problem. He was 57 on my meter and he gave me a 57 report back. OK, so now I know something's afoot inside my K3.

[Elecraft] K3/P3 combo during ARRL RTTY RU
Hello All: I wanted to give - or chime in with - my impressions of my K3 performance with my new P3 panadapter. I run an SO2R setup with the K3 (with rebuilt TL-922A amp) as the #1 rig and my venerable FT-1000MP MkV (with 87A amp) as my #2 rig. The K3 is the only rig with a panadapter. This was my first contest after a station rebuild project which lasted over a year and a half. It felt great to get back in the saddle again and I really love RTTY as a contest mode. I use N1MM Logger as my contest software. I found the use of the panadapter was quite useful when I switched roles for the rig and used it for SP. It was really neat to be able to spot RTTY signals on a noisy 80M band and work them quickly. I have also found that in a contest scenario, I have better luck turning off the dual peak filter and just maintaining a narrow filter skirt around both mark and space. The reason for this is that I can 'see the signal coming' when I tune for stations much easier and can quickly 'lock on' and work them. Now I wish I had a panadapter for the Mark V !

[Elecraft] BNC adapter question
Hello: I received the PR-6 6M preamp for Christmas. I have found that it eats up a lot of shelf space hanging in the back as it does. I thought it might work if I could flip it up, but I can't seem to find a BNC right angle M-M adapter. Does anyone know if these exist or have other ideas ?

Re: [Elecraft] KPA 500
Hello All: I guess I'll throw my 2 cents worth in the pot. I have been waiting for a QRO amplifier from Elecraft for some time now. I've truly enjoyed all my Elecraft products which include four radios. The build of the K2/100 was the richest experience and I learned a very great deal. The QRO amplifier was talked about and a prototype was displayed many years ago now. I finally decided to put to use my 20 year old Kenwood TL-922A amplifier. The problem was that it required a buffer between the newer radios and this amp, it was a noise maker with its heavy relay, and had problems with flash over most likely due to VHF parasitics. There is a great deal of information on upgrading this finely built amplifier on the internet and I finally took the plunge to do the modifications. It took a couple months to gather up items needed and do the mods but it now has an electronic cathode bias circuit, full QSK using the little Gigavac GH1 vacuum relay, a step start circuit using that big noisy relay (it only snaps shut once now!), no ALC circuitry, modified VHF parasitic suppression, and I can drive it equally well with my Drake T4XB or my K3. The project was fun, I learned a very great deal, and the result was excellent. No more flash-overs and clean output. And the old girls, the 3-500Z's, are still shining well. The one thing that is missing is 6M amplification. This is where the new Elecraft KPA-500 will do well. I believe the new 6M Alpha (RF Concepts) amp will cost more than the KPA-500 but it will give you 1500 watts - easy. The new solid state technology with light-weight power supplies is certainly the way of the future and the small matching Elecraft footprint is a definite plus especially for DXpeditions. Will I buy one ? It depends. It will be very hard to part with my modified TL-922 since it is now 'personalized'. And with the experience and knowledge gained from that process, I may decide to build a 6M amplifier to round it all out. Now if Elecraft were to come out with a KPA-500-6M 6M only amp .

RE: [Elecraft] K3 RF Feedback Problem
Hi Jim: I'm wondering what external station controller you are using. I'm using a NCS Multi-Switcher and I ran into very similar issues. I certainly felt (as did Doug at NCS) that it was a ground loop problem. I used transformer isolated mike cables and found that it was NOT a ground problem. I can give you my long details, but the bottom line is that the mike gain in the Multi-Switcher (internal) needed to be driven a bit higher than normal, and the mike gain on the K3 need to be quite low (5 or 6) to avoid the 'growl' effect. I'm forwarding this to Doug at NCS as he is quite interested in what's going on that might be causing this. 73, Jamie WB4YDL _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dr. James C. Garland Sent: Saturday, November 01, 2008 8:57 AM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 RF Feedback Problem Gang, I'm pulling my hair out over an RF feedback problem with my K3/100, and wonder if anybody has any ideas? I use an external station controller that switches key, microphone, CAT, line in/out, etc. between different rigs. The microphone audio connects to the K3's rear panel microphone jack and when the K3's power exceeds about 15W (in SSB), the audio becomes greatly istorted. It does this when all the other cables to the K3 (except the microphone and power cord) are unplugged. It also does it when the audio is fed to the K3 via the rear Line In jack. Everything in my station is well-grounded. Here are some things I've noticed: 1. The feedback still occurs when a military-type completely shielded 100W dummy load is screwed directly to the K3's antenna port. This suggests the RF from the K3 is getting into the audio line from some other source than radiation from the coax cables in the station, most likely the 12V power cord. To support this conjecture, I also notice that the feedback threshold (15W) is not changed when the K3 drives a linear amplifier. 2. I normally use a 30A Kepco 12V power supply to run the K3 and my other station accessories. The RF feedback problem is improved but not entirely eliminated if I use a separate 12V supply for the K3. A common mode choke on the 12V line doesn't appear to make any difference. 3. I can see some modulation-induced fluctuationss on the 12V line with an oscilloscope that increase with the K3's power setting. I haven't looked at these fluctuations closely enough yet to know whether it's RF noise or just audio-frequency fluctuations caused by the K3's modulating current draw from the power supply. To summarize, my conclusions so far are that (1) the 12V power cord is a source of RF leakage from the K3, even though the K3 has a filter at its 12V power connector to minimize this leakage; and (2) The audio/DSP circuitry in the K3 is very sensitive to RF - much more so than other transceivers in my station. (I've not had this problem with other rigs.) Because of this RF sensitivity, one evidently has to be very careful when hooking accessories to the K3. The front panel microphone jack is (to me) wired in a curious way, with the Mic ground and PTT ground (shield) connections floating above the K3's chassis with a 100uH rf choke. Similarly, both the hot and shield side of the rear panel mic input jack has series 100uH rf chokes, which isolate the input from chassis ground. The problem with this arrangement is that most accessories that would connect to the rear panel audio input jacks have single-ended outputs, with a shielded cable that is directly tied to chassis ground at the accessory end of the cable. Thus, unless one is very careful, it is easy to have a situtation where the signal grounds in the audio circuitry of the K3 can fluctuate with respect to the K3's chassis ground, and this may be the source of the RF feedback sensitivity. Unfortunately, I can't figure out the detailed mechanism for the feedback closely enough to figure out a solution. Foir example, I don't know whether it's better to leave the minus side of my 12V power supply floating, or to tie it to the chassis gound.. And even if I left it floating, it would be tied to the chassis anyway by the other accessories hooked to it, and this might cause more problems than grounding it at the power supply terminal. Somehow, it seems like a wiring change in the ground configuration of the K3's audio circutis to improve RF isolation may be needed to lick the problem completely. 73, Jim Garland W8ZR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Thinking that this was a classic RF on the line problem, I clipped on multiple ferrite chokes with many turns on the cable coming from the K3, the Goldline mike, and in between the switcher on noise gate. This didn't even slow it down ! Hmmm. Interestingly when the PA relay is off at 8 watts, there is absolutely no hash. For now, I'll just use the hand mike on 6M (which requires a bit more mike gain) to keep a clean signal. Has anyone else noticed this ? Got a solution ? 73, Jamie WB4YDL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] K3: 6M SSB audio hash
Thanks Don: I still suspect the 10' cable to the NCS Multi-Switcher is acting like an antenna at that high a frequency - however, nothing changed with multiple ferrite chokes along this line. Good idea to check the back mic connector, although direct attachment of the hand mike and the headset to the front connector did not cause the hash. The cable is a very well constructed cable made by NCS for the K3 (Kenwood). I can certainly ask NCS (I forgot his name, but he's very approachable) regarding the shielding characteristics. I use the same cables for the other radios. You asked if it gets worse with increase in power - yes, but not very much. It's nearly an all or nothing deal. When using my K2/100 with 6M transverter through the W2IHY unit, there is no problem at all. The only difference is a longer cable to a different port on the multi-switcher to reach the K3 - which is on the other side of my monitor/desk. 73, Jamie WB4YDL -Original Message- From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Friday, June 06, 2008 5:17 PM To: James C. Hall, MD Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3: 6M SSB audio hash Jamie, The Heil headset will plug directly into the rear panel jacks - why not give that a try as an added piece of evidence that it is not the microphone. Most likely, something is being picked up on those long microphone cables and is not a K3 problem at all. Are all the mic cables shielded? Are all the cable shields connected to the plug/jack shell? They should be. I have not investigated the W2IHY equipment, but my understanding is that it is setup primarily for pro mics which use balanced AF lines for the mic audio. My suspicion is that there is something awry with the balanced to unbalanced arrangement when used with unbalanced line microphones such as you have there. As far as why it shows up only when the PA turns on, I can only speculate there too, but remember that there is more gain in the transmit stages when the PA turns on, and that added gain may make any small AF line pickup more pronounced in your transmit signal. If it were from RF coupling into the audio, it would vary smoothly from low power to high power and all RF levels in between - you indicated only that it was there with the PA on, but did not say that it got worse as power was increased. 73, Don W3FPR James C.

[Elecraft] K3 USB-serial adapter recommendation
Hello: Well, after trying several permutations to try and figure why software was unable to poll freq/mode, I have discovered that the K3 doesn't like my usb-serial port adapters. I have two available - Keyspan 4-port and a USBGear 2-port. Both have worked admirably with everything - until now. When I re-hooked my K3 back to the shack computer with a true serial port, it connected immediately - no sweat. CW keying was never a problem with the USB adapters.

[Elecraft] K3 interface with N3FJP FD software
Hello: I was setting up for using the K3 for FD this year and am having a problem getting N3FJP FD software to do rig control. This may belong and likely will go on their reflector as well, but I wanted to see if anyone else has noticed any problems here. In the software, I choose Elecraft as rig type and 4800 8-n-1 and the correct com port. Polling the rig fails. I'm just not sure why. I'm using a Keyspan 4-port serial to USB adapter that we've used successfully with the K2 for years. It will do CW keying just fine.

[Elecraft] K3 RTTY Com port issue
Hello All: I'm really enjoying my new K3 #616. I've been getting everything hooked up and exploring all the possible solutions to typical problems. Here's one that I haven't seen answered here - To run RTTY with MMTTY requires use of the one Com port on the radio unless you choose to use VOX control. This works quite well until something like an APRS burst kicks in and sends the transceiver into transmit ! If you run a logging program - mine is LoGic 8 - it uses the Com port to control the radio or just put in the frequency information when you make a contact. Running BOTH programs takes 2 com ports. Now, if I use a program like MixW, this CAN use one Com port is you stay with AFSK. I have not yet run a cable for FSK to a separate Com port. Is there any slick way to avoid the Com port conflict ? I DO plan on upgrading my interface situation with a microHAM device, so this is probably an academic question. I would just like to hear what others have figured out ! :) 73, Jamie WB4YDL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Automatic 1:1/4:1 Balun switching under K3 control?
It could be that the relay could be switched by sending DC voltage up the coax, particularly if the balun is a good distance from the radio - much like turning on a pre-amp on the mast. 73, Jamie WB4YDL wayne burdick wrote: Leigh wrote: This is great! I had been meaning to ask because I have use a switchable BL2 ony my big loop and had no way of knowing what the KAT3 was doing in the 1:1 and 4:1 positions, other than how long it took to find a match. This is certainly one excellent use of the KAT3's LCSET mode, Leigh. You've also given me an idea for a BL3: Same as the BL2 but with a relay rather than a switch for selecting 1:1 vs. 4:1. We could then use one of the K3's spare output lines (say DIGOUT1) to switch the relay under firmware control, per-band. There would be one wire running from the AUX I/O connector to the BL3, and you'd need to power the relay from the K3's switched 12 VDC accessory output. If this is of interest, I'll ask the BL2's designer to take a look at it. I have the same problem myself, so I already want two :) 73, Wayne N6KR On Thu, 20 Dec 2007 10:55 am, wayne burdick wrote: If you're ever curious about the actual L and C values used in the matching network, you can check them using a special setting of the KAT3 menu entry (in the CONFIG menu).

As I pulled into my driveway I noticed a large white box resting on the door step, carefully placed to avoid the puddle of water created by the mis-ajusted lawn sprinklers (I've just gotta take care of that one of these days). But what could be in the box? Had my wife ordered yet another something from welovetoshop.com? I approached the box with caution as you just can't be too careful about strange packages these days, just think about what they do to unattended luggage at the airport! As I gazed upon it I had this hazy recollection that I had recently seen a similar container, but where? Yes, it had been a picture of an attractive young lady holding it and yet another picture of a white bearded man holding one of these boxes, flanked by the same lady! There must be a connection! And then I recalled I had actually met this lady, but where? As I drew closer, I could see what appeared to be a shipping label . Well, that should answer the questions. Return address, Elecraft. Oh, that little purveyor of ham radios down the coast in the quaint little village of Aptos. I searched my memory as to what this could be. The last thing I had ordered from them had been a shield upgrade kit for my K2/KPA100 so I could move the KPA100 back from its home in an EC2. And then it hit me...many months ago at the DX convention in Visalia I stopped by the Elecraft booth and saw a new product, the K3. Nice looking radio, sorta like a K2 on steroids. Upon further investigation it was far more than a K2, with features available only on $10k radios, and some available nowhere else. As soon as I expressed interest in perhaps purchasing one, one of Eric's goons wrestled me to the floor and Eric shoved an order form into my hand, while extracting a credit card from my wallet. Just sign here and by the end of July, you will have the best radio in the world! July passed as did August, as well as September. By that time I had managed to repress the memory of actually ordering the radio, firmly convinced that Eric and Wayne had absconded with the down payments and moved to Brazil, living the good life. Yet this must be it, the K3! Still skeptical, I haulled the box back to my allready cluttered work bench, whipped out my 60 year old Boy Scout knife (yes, I have achieved Old Fartdom), cut through the sealing tape...and there it was, lots of pieces of a K3,all packaged in ESD proof plastic. But now the search for the single most important component of an Elecraft radio, the serial number! Mine is smaller than yours! So far nothing obvious on top so need to dig deeper. Check the back panel and it has not been pre-serialed. Damn, I'm down to the rf board and still nothing but lots of hardware. It looks like someone dumped the screw bins in a hardware store on the floor and tossed the result into a single drawer. But I digress, only one more layer to go, and there it is! The Holy Grail! With trembling fingers I open the envelope with the S/N tag.it's, it's ...#23. Outstanding! And now where DID I leave that screwdriver?... Created under the influence of Pink Floyd.

In NAQP RTTY, I used a K3 and a ProIII. The K3 was connected directly to the PC soundcard input whereas the ProIII had an audio isolation transformer in line as well as a JPS NIR-12 audio DSP. The K3 performed at least as well, if not better than the ProIII. Other field testers, e.g., N6XI, use AFSK and therefore are connecting their K3 to the soundcard input and output will great results. The K3 is designed for direct connection to soundcards with its LINE IN and LINE OUT jacks on the back panel. Each is fed from an audio isolation transformer inside the K3. The K3 is the best equipped radio for DATA modes and direct connection to PC soundcards. 73, Ed - W0YK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

If the firmware for the K3 would allow transverter operation on 28 through 32MHz and some other reasonable IF (22-24 MHz?(I have no idea what would really be right)), then we could use the K3 for full-duplex satellite operation. And if a repackaging job could be done to combine these two units in a single package, then a lot of external cabling might be disposed of, and it might be made to match the K3. 73, doug ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Type N connectors
Don, et al: What a great thread ! I have only experience with crimping BNC and SMA connectors and, strangely enough, LMR-600. Yep, I borrowed the crimping tool for LMR-600 which is outrageously expensive from a cell telephone outfit here in town. The owner is a ham friend of mine and he gave me an N-connector to go on my long run on LMR-600. It has worked flawlessly. Don, I use the correct crimp tool (I got mine from West Mountain Radio) for Power-Poles and it works great. Sometimes I will both crimp and solder them. I've never crimped PL-259's or N connectors but, brother, would that have saved some time around here !!

The prior information I have from NASA and for avionics applications is that crimping is the preferred method of fastening. The only reason I can think of to vary from that in the field is that the proper tools may not be universally available. As has been pointed out, a proper crimped connection requires the proper tool and connectors designed to be used with those tools. Vary either piece of the equation and you end up with an unreliable connection. You can take some shortcuts with soldering, but if you crimp, make certain all the elements are correct. For instance, I do not crimp my Anderson PowerPole connections - because I do not have the correct tool - I have tried the low-priced model, and I have experienced several connector failures and have gone back to soldering them. 73, Don W3FPR Brian wrote: Hello all, Just my 2 cents.

RF Connection http://www.therfc.com/ also has an interchangable die tool that's more reasonablly priced, but again I can't be sure it's the same. It looks the same, but it's hard to judge a tool without having it in your hands. And Don is 100% right, a cheap tool is no bargain if it breaks or does not do the job right. I would look for a ratcheting type tool, as crimping RG213/214 size cable requires a lot of pressure and the ratcheting feature helps. I don't think even a ratcheting tool will work for larger cables, such as LMR600, where you need a lot of force. I believe those use a hydraulic crimper.

I switched to crimp-type connectors quite a while ago and find them superior to solder-type connectors. Some crimp connectors are double-crimp, i.e., both the center pin and shield are crimped and others have a solder-type center pin and crimp shield. It's important that the crimp connector be the correct one for the coax type and that you use the correct die size, of course. Some crimp tools have interchangeable die sets and others are made with a non-removable die. If you decide to buy a crimp tool, shop around, as there is at least a 2:1 price variation from supplier-to-supplier for what seems to be the same tool.

I looked through the LA3ZA K2 mod information and saw that Pauli (EA3BLQ.SK) had a board that would solve the issue that I have. So, here come the questions for my fellow Elecraft K2/100 owners 1) Has anyone on the Elecraft list added a dedicated HF digital port to their K2? 2) Did they use Pauli's board?

[Elecraft] XV50 transverter update
Hello Don and Ron: I got my new power module in the mail today and it went right in without a hitch. Alignment at that point went very smooth. I used a DL-1 to measure voltage and then chart it out to 20 watts. My LP-100 is waiting to be built. :-) I figured 22 volts was about 20 watts and that worked great. All the other parts of the alignment went fine except: Part IX: Overload Protection test - I couldn't get this to work. Removing the jumper JP8 removes power from the transverter. This can be turned on manually with the power switch, but I left it off as the instructions said nothing about it. Removing the serial control cable, disables the transverter entirely - no power with or without the front switch on. Keying the transmitter resulted in nothing except a higher SWR light on the KAT100. LO Oscillator Frequency Calibration: Using my Mark V on 12M, I find I'm off on 6M by about 700 Hz. But where the heck is Z6 trimmer capacitor. I suspect it should be C64, since I haven't touched that one yet. :-) 73, Jamie WB4YDL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I'm using whatever the mic is that Elecraft sells so I can't comment on your mic. The Y serial cable goes to the KAT100, K2, and the computer end connects to the microKEYER. The microKEYER has a separate USB cable that goes to the computer. There was no gender-changer needed with the K2 cable set that came with it. I haven't figured out RTTY or PSK31. Just CW and phone.

Well, I must humbly submit my most recent gaff. It's nothing like landing long on a short runway (yikes!), but it relates to my inquiry on troubleshooting my JPS NIR-12. For several days now, Don W3FPR has been trying to help me figure out why power was not being applied to this unit. It was thought to be a bad diode running in series in the 12 volt line. Why was I getting 13 volts on the anode and virtually no volts on the cathode side. It was as if there was no ground on the cathode side of the circuit. I tried shorting the diode which made an impressive smoke job of an electrolytic capacitor shunting to ground. Well then I retraced my steps. I discovered that when I pulled the unit out of the shelf, the Radio Shack modular power plug (which goes to a 'wall wart') came off the 2-prong saddle on the wire. I merely plugged it back in the saddle. The AHAH moment came when I checked the polarity of the plug - I had accidentally reversed the polarity of this plug (VERY easy to do with these modular plugs). The diode was simply doing what it was designed to do - protect the unit against dumb things like this. In the immortal word of Homer Simpson - D'oh !!! Don, thanks for being SOo patient with me !!! 73, Jamie WB4YDL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] OT - troubleshooting NIR-12
Hi Don: I was hoping you might lend a hand. :) OK, now this may show how much I've forgotten but for the symbol of a diode, the 'arrow' side is cathode and 'plate' side is anode - right ? The schematic drawing of this unit definitely shows the 'arrow' side towards the +12v source. -|- Cathode - anodeRight ? This would prevent reverse voltage but not forward voltage. So I should not have seen a different voltage on the 'plate' side of the diode - if I understand correctly. 73, Jamie WB4YDL -Original Message- From: Don Wilhelm [mailto:[EMAIL PROTECTED] Sent: Saturday, December 31, 2005 7:32 AM To: [EMAIL PROTECTED]; 'Elecraft List' Subject: RE: [Elecraft] OT - troubleshooting NIR-12 Jamie, If the diode is in series with the power line (as a reverse voltage protection diode), and if the unit is being fed with a positive voltage, the anode lead should be connected toward the +12 volt supply side. Since you said there was voltage on the cathode but none on the anode, it would seem to me that the diode may be installed backwards - and that would produce the result you are observing. 73, Don W3FPR -Original Message- I know this has nothing to do with Elecraft gear, but having built the 3 radios, I knew this is the place to come for experienced troubleshooters. I have an old JPS NIR-12 DSP unit, that, after applying power, decided to quit. The power lamp will not now light. This unit does not have a fuse. So I decided to get out the DVM and attempt to see what's going on. The DC power jack goes to a T-network consisting of two 0.1 uf caps with a bead inductor before going to a DPDT switch. Beyond this is a 0.1 uf cap in parallel to ground and then a series 1N4004 rectifier diode to a 1000 uf electrolytic capacitor in parallel to ground. From there it branches to a couple of voltage regulators to get different voltages. When voltage is applied, I get 13.7 volts on the cathode side of the diode, but zero on the anode side (and beyond). I initially thought that this diode was at fault and desoldered it and replaced it with another 1N4004. But, alas, this was not the culprit. I desoldered the 1000uf electrolytic, but my capacitance meter reads it correctly at 1000uf. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] SKN rigs
Hi Eric: Your web site is excellent. It brought a lot of memories. My first rig was the Drake R4-B and the 2-NT. Later when I passed the General, I replaced the 2-NT with the T4X-B. I still have them all, but the 2-NT is in a box in my storage room. I, too, never found a suitable VFO for it, but God if we only new about VXO's in that day !! HI I was a high school sophomore in 1971 with my Novice ticket - WN4YDL - living in Memphis. I now also have built the Elecraft line - K2/100, K1, and KX1. I just may have to try this 'VFO' out ! I certainly need to get the Tarn-X out and start cleaning up these great old rigs. I saw where an outfit called Misty Hollow is developing DDS gear for the transceivers of the day, but I don't know if they have anything going back to the separates. 73 and Merry Christmas, Jamie WB4YDL -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of EricJ Sent: Friday, December 23, 2005 12:17 PM To: 'Elecraft' Subject: RE: [Elecraft] SKN rigs On STRAIGHT KEY Night, I'll be using the Drake 2-B, 2-C and 2-NT, not surprisingly with a Speed-X STRAIGHT KEY. The VFO for my 50 dollar Drake transmitter is an Elecraft K2 into a DL-1 for about 2 vrms into the FT-243 crystal socket. My apologies to boatanchor enthusiasts everywhere.

Finally, I called my sister, the Rocket Scientist (actually, we're not _Rocket_ scientists - That's a quote from her husband) and asked her. She and Paul spent a few minutes on the problem, figured it out, but it was such a trivial answer they threw it away. Since I'd spent so long on the Question, I gave her about a week and then I called back. Luckily they'd not taken out the trash, so she easily found their notes and read them to me. I won't spoil it for you 'crafters. Dan / WG4S / K2 #2456 Problem: An alley has a 20-foot ladder across it, in the left lower corner and leaning on the right wall. There also is a 30-foot ladder, from the right lower corner leaning on the left wall. The laders cross at 10 feet high. How wide is the alley? Usual conventions: alley is all right angles, ladders have no thickness nor bends, blah blah blah... This should make some juices flow out there. Just simple geometry, or is it?
