K3 - KRX3
Locked
 
|
After reading all of the stories of problems with the KRX3, I've decided not to install the one I received a couple of months ago. I originally planned to wait and see how other installations played out especially after reading that the front panel had to be removed and messed with in order to do the KRX3 installation. That's the last thing I wanted to do. I took extreme care with the front panel during the initial kit assembly and had no problems at all. I think that taking something like the front panel assembly apart is just asking for trouble. I'll bet others now agree with me. I ordered my KRX3 as part of my original purchase just after Dayton in 2007. Had I really understood all that would be involved with the KRX3 installation, I would have waited until it was available and done the whole thing at once. Even though the KRX3 manual might have been available at the time for customers to review, I didn't. There just aren't enough hours in the day. I
do think that Elecraft should have emphasized the fact that front panel disassembly would be required if the KRX3 was not installed at initial build. Especially when you consider that the KRX3 was listed right along with all of the other K3 options on the glossy brochure that everyone grabbed at Dayton, 2007. Since the KRX3 was listed as an available option, I ordered it along with everything else. I even fronted Elecraft 50% up front and got nothing in return.....but that's another story. As I said, I hold Elecraft guilty for the KRX3 issues. I don't think it makes sense to take the radio apart to install an option that was delayed for a long time. At the very least, the issues associated with the KRX3 installation should have been made a lot clearer. If anyone who has read this far is interested in the KRX3, I have mine available at a lower price than what it is currently going for. I bought it at the initial offering price. I also have an extra 500Hz filter that was designated for the KRX3. If interested, please contact me off list via e-mail. 73, Dave N8AG __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Hundreds of KRX3's have been installed without problems, but you only read about the horror stories on the reflector. It takes a few hours to do if you work slowly and carefully, and taking the front panel apart is not hard at all. The instructions are good and the secret is just to take your time and follow them. If you assembled the K3 in the first place you should have no trouble. There are no 'issues' with the KRX3, and if you have a problem Elecraft will help you out. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I could be wrong, but I'm under the impression that a sub-rx add-on only needs to have the front panel removed, not dis-assembled. I have had no trouble at all with the second rx - works as advertised and I'm happy. My only K3 problem is with the output jumping up and down unpredictably. As far as pushing the wrong buttons is concerned, I'll get used to it.

The second DSP attaches to the main DSP board with three standoffs and screws, and then it goes back together. As an aside, when the DVR comes out, you have to drop the front panel as well. The DVR attaches to the main DSP board with a single standoff and screw. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The posting below shows that it is possible to complain about anything! I
have a very different perspective on what is expressed below. In fact, pretty much the opposite. There haven't been any more "stories of problems" with the KRX3 than other aspects of the K3. And, overall, the total amount of K3 issues has been negligible given the complexity and high performance of the radio. The only "problem" is that Elecraft provides this reflector to make it trivially easy for anyone to highlight some problem they are having and get a quick resolution in most cases. Far more postings deal with problems than report "all's well with my K3". It is inappropriate to subsequently conclude that the KRX3 or K3 or K2 etc. have some abnormally high number of issues for users. Many K3 customers have found the assembly/disassembly and addition of options to be easy and actually quite enjoyable. Other K3 customers are not inclined to get involved and prefer the factory-assembled option. Either way is perfectly acceptable and Elecraft is the only major Ham radio manufacturer to offer that choice to cover the diversity of our interests and skills. The K3 front panel assembly is designed for disassembly/re-assembly countless times ... many more than will ever be needed by even the most contrived situation. That doesn't mean that these operations are trivial for everyone, which is exactly why the factory-assembled alternative exists. Many customers return their K3 to Elecraft for installation of the KRX3. That's not a problem, but instead one of two equally acceptable choices. The 50% deposit alternative has always been clearly documented on the web site and written materials. It was clearly stated what the deposit would get for the customer and what it would not get. More than anything it was a way for us to express our support of Elecraft. The biggest return we are getting from those deposits is a well-managed company that is providing exceptional products for us to enjoy. Given all the other company choices for a state-of-the-art Ham rig, the 50% deposit is a high-return investment. Every "problem" described below is actually a misrepresentation of a huge success story for Elecraft and their customers. 73, Ed -W0YK > After reading all of the stories of problems with the KRX3, > I've decided not to install the one I received a couple of > months ago.

I too ordered my Factory built K3 with the KRX3. Well it wasn't ready when my rig shipped (#806), but I left it in the order. Guys like Ed scared me half to death with all the stories about the front panel disassembly. Although most of them called it a disassembly, which it is not. Actually after receiving my KRX3 a couple of weeks ago I can tell all of you that those who whined about removing the front panel were wrong. I actually thought it was the simplest part of the installation. It's not a disassembly; It's a removal. My KRX3 worked the first time I turned the rig on and did the setup as described in the manual. The diversity RX is wonderful. On the lower bands I'm using vertically polarized TX antennas and an 80 full wave loop for diversity RX. It's so much better than RX with one antenna! By the way my 80m loop is at 30 ft at the highest point and 10 feet most of the way around my standard size city lot. I don't use it for TX, but it sure takes the fading out of 80 and 40m work. If you want a KRX3 and can afford it get one. You won't be sorry. N5GE >The posting below shows that it is possible to complain about anything!

It then goes back on. I have fitted (and in one case back engineered and refitted) 3 sub-rx's now with zero problems. The only reason I had to back engineer one was for a problem that occurred that was nothing to do with the sub-rx. I always recall Elecraft telling us that the sub-rx required some work on the radio and as it got closer they also showed us it in photographic form. The point is the fit is straightforward. If you built the K3, it is almost trivial in comparison and works really well! The K3 is a 'kit' and occasionally you might have to do some work on it just like the K2. In fact some of the stuff on the K2 (like the 60m board) required some mods to the main rf board. My advice to anyone contemplating the sub-rx fit is just to do it. It enhances the radio and is not difficult to do. Your enjoyment of the radio will increase, especially if you have a vertical and a horizontal aerial for the same band in diversity mode! 73 Ian -- Ian J Maude, G0VGS SysOp GB7MBC DX Cluster Member RSGB, GQRP K2 #4044 |K3 #455 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Of course that's still an option. There's a ready market for K3s and I suspect you could sell your existing unit for at least what it cost you, and probably closer to what an assembled unit costs if you've done it carefully. I really enjoyed building my first unit, but decided to build another from scratch when the KRX3 became available. I may do the same if I ever decide to add the KDVR. I'm quite sure I could install these options after the initial build, but I simply enjoyed the build process so much I chose to build my KRX3 unit from scratch. Regarding assembly issues, there appears to be a great variety of skill levels of people doing this successfully. If you can follow directions explicitly, I believe you will have no problems. Many of the problems I see on this list result from those who do not follow the instructions exactly. Having used my KRX3 on 160 since QRN levels have dropped, I would not want to be without it. I distinctly recall several QSOs in the Stew Perry Warmup this weekend where diversity saved repeats due to QSB. I remember one QSO where the DX signal shifted from left to right in my headset as he was sending the exchange. If I had been listening on either antenna alone, I would not have copied it without asking for a repeat due to the rapid QSB. And I have no idea how many more QSOs I made due to hearing people calling from different directions than my primary Beverage. The KH6LC crew reported good results by transmitting on an omnidirectional vertical and listening toward JA and USA simultaneously on Beverages using the K3 in diversity. There is *NO* other radio on the market today that can do this as well as the K3...not the IC-7800 and not Orion. 73, Bill W4ZV |

Exactly as Bill describes it!

I believe ours was one of those contacts, I was working the warmup using my SE0X call and I was definitely hearing U better in my end. But QSB was deep and you where up and down in the noise level. For practical reasons I was not using diversity, but I have the same experience as you. The second RX is really worth the investment and the downtime to install it.

Aha! So it was you with that strange callsign Bjorn! I've never heard an "SE0" before and my brain/ears were trying to make sense of it as I was madly switching antennas to try to peak the signal. I first thought it was an "NE0" so I was switching my antennas West. Unique prefixes are not always an advantage if the operator on the other end does not recognize them! Here in the USA it can also be confusing if a station is not in the direction indicated by the number in their call (since you instantly lose the signal if they are not in the expected direction of your RX antenna selected). I also have the 2.7k and 500 in both RXs for diversity, but additionally have the 1.8k and 200 in my Main for serious contesting. I've found that even using the 200 in Main and 500 in Sub does not cause serious problems in diversity, even though the filters have different offsets...but this might not be the case for everyone. 73, Bill W4ZV P.S. Next time I'll probably recognize SE0X! |

Hi, Dave, Wow -- I know exactly what you are talking about! I received my KRX3 and there it sat in a box for two weeks. I was more than a little scared to install it after reading about some of the horror stories on the reflector. Two weekends ago I took the plunge. I set aside an entire Sunday, cleared the work bench, and dived it. I have to say, quite honestly, that it was much, much easier than I could have imagined. I think being a little scared might have helped, as I was VERY careful and took my time. However, it all went together ridiculously easy and I had no problems whatsoever. The front panel was much easier to get off and reinstall than it was the first time I put the K3 together. In the entire process, the only problem I had was a bent screw. The decision is yours, but I wouldn't hesitate to do the install again. Good luck and 73 . . . John, WA6L

I didn't read the reflector for all of the horror stories, but I didn't install mine right away because of work - the same reason I checked out of reading the reflector for a while. I finally did it a couple weeks ago, and did find it to be rather involved - but at no point did I feel like I was out of my depth. I don't consider myself the most mechanically able guy by any means. I will admit that when I saw that the front panel had to be removed, I did groan a little. I remembered that the initial assembly and install had been kinda gnarly. But the instructions were very clear and you only have to remove the items that are strictly necessary. A lot less trouble than I feared! By the time I was done I realized that, in a way, by doing all of the necessary disassembly and removal and re-installs, it was kind of like getting to build another radio.

I can just confirm that after 4 hours job on kitchen table without any
complication I have new KRX3 module inside, calibrated and with all filters I ordered for it. Also DSP f/w loaded, simply finished. There was no horror scenario, board fitted inside correctly, no need to modify R91 etc.... Also having version without nylon standoff for main DSP but suppose it is used as mechanical support only to avoid touching boards or some long leads problems which is not my case. There are basically three main "actions" as KSYN and SUB I/O boards and AUX ant cable install, then Front panel DSP addition and KRX module itself - you can plan and study all from manuals just before and ask for anything unclear, really there is no trap or hidden beast inside :-) Dissasembly/assembly of DSP BD and Front panel was not done first time here so maybe I am little bit more experienced but really no problem. The more iportant challenge was to fasten AUX ANT Bnc and organize coax cables around PLL... Now connecting antenna and will test split on VK9WDX on 30m :-) GL to all K3 builders, thanks to Elecraft and 73!

The filters don't need to be matched in bandwidth but they do need to
have the same frequency offset to avoid possible "beat note" problems between the two (main/sub) synthesizers. I didn't bother to pay the extra 60 bucks to frequency-match the 2.7 kHz in the KRX3 with the old one in the main receiver. The new one came in 100 Hz different than the old one, so I just split the difference and entered the same offset for both. A 50 Hz error is not significant in a 2.7 kHz filter.
