[Elecraft] KRX3: Poor Sensitivity on Aux Antenna Port
This evening I finished installation of the KRX3 that I ordered back in April, and I ran into a problem with poor sensitivity on the Aux port I thought others might be interested in. After I completed installation of the KRX3 and went through the requisite VCO calibration, filter setup, etc., I found that the receiver worked flawlessly on the main antenna, but sensitivity on the Aux port was poor (about 30 dB below that of the Main antenna port). Thinking that I might have a bad TMP cable from the KRX3 Aux port to the KAT3, I pulled the KRX3 out, removed the KRX3 circuit board from the shield, and used an ohmmeter to confirm continuity. All was well. I reassembled the KRX3 and reinstalled it, same problem. I then removed the top portion of the shield while the KRX3 remained in situ, and sensitivity on the Aux port was normal. Spark arrestor, SA1, is mounted very close to the edge of the circuit board. In my KRX3, this component has "leaning" towards the outside edge of the board sufficiently to allow the top shield to short it to ground. Bending the leads of SA1 just slightly so that it was away from the edge of the board resolved the problem.

[Elecraft] K3 Procat Cool 5.5 Update Rev 75
Hello all, I've been coding again and have added front panel AGC threshold control to the K3 Procat Cool 5.5 program in addition to DSP filter width. Cool Setup also allows you to choose a value (2 to 8) that the threshold will be set to upon execution as the starting point. Stop by and check my page if you are interested. 73, Don http://tinyurl.com/5a5ak5 http://www.zerobeat.net/mediawiki/index.php/Procat_Cool_for_Windows ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] OT: 160/80 M Rx loops
I've had enough off-reflector questions about my loop that an on-reflector reply is probably warranted. I've had mine in use for 25+ years and early-on had it mounted on a small TV rotator. The directional characteristics of a loop are such that there's little/no reason to rotate it -UNLESS- you want to take advantage of the very deep and narrow null off each side of the loop to null noise ... or the mega-KW ERP contest station ... in the next county. (;-). My loop is made from 1/2" "hardline" with a 1/8" break in the shield at opposite the feed point. Either 50 or 72 ohm coax is OK ... there's no difference in this application. The circumference of a loop should not exceed .06 wavelength, BTW. There is a two-transistor preamp at the feedpoint of mine that's powered w/12VDC via the coax running to the loop. The feedline is about 500' of 72 ohm (RG-59) coax. A Google search of "160M receive loops" or "BCB receive loops" will produce lots of information. Some "serious" loop users ground their TX antenna ... especially verticals ... while receiving because of the re-radiation of noise from the vertical into the loop. 73!

Listening in the headphones, I detect little difference in weighting and T/R recovery time. I made that comparison while listening to the side-tone.

Re: [Elecraft] K3: New/ Old QSK
Go to CONFIG and select CW WEIGHT. Then press the "3" key on the numeric keypad to toggle it. It doesn't seem to make much of a difference for me. 73, Vic, K2VCO Using the most current K3 F/W, I compared the New versus Old QSK configuration using a dual-trace scope and an external keyer modified with a buffered output for scope triggering. Under the "Old" QSK setting, the CW envelope rises ~ 15 ms after contact closure versus ~ 19 ms for "New." Under "Old," the keyed RF envelope more closely matches the external contact closure duration. Listening in the headphones, I detect little difference in weighting and T/R recovery time. I haven't had time to compare the two modes under varying AGC and band conditions, but unless I detect some anomaly, I am leaving my K3 set for "Old. QSK."

Good Evening, As I sit here the sky is fading from a very nice sunset. The day was clear and crisp with full sun until late in the afternoon. We are due for some more rain but this week has had a few days of sun; unusual for Oregon this time of year. On a short hike today I did find some signs of frost in the shade. Winter is on its way. Propagation was pretty good on twenty meters this week but that was before the latest solar stream hit. I was told things got a little odd after that but I have not been on the air to hear for myself. I will check into the MARS net tonight (I hope) to see what conditions are like on the lower frequencies. Hopefully all will be well for tomorrow's nets.

Re: [Elecraft] HPS-1a Gamma Hybrid,Communications Power Supply
It works at 100W SSB with 10-20dB compression. For CW at 20WPM you need to go down to 70W or so. It would not be good for RTTY or MFSK or other 100% duty cycle modes past 20W or so.

RE: [Elecraft] K3: KRX3 hearing no Signals

[Elecraft] K3: KRX3 hearing no Signals
For future reference for people searching as to why there KRX3 is not hearing any signals be sure the filters are installed in the slots they are supposed to be. You will have noise and the sub controls will work but you are not hearing any signals. I know what I am going to write sounds simplistic but read on there is more to it than one would think. I am well aware of filter placement as I have put together two K3's and as I was putting the KRX3 together my XYL Edith W0OE mentioned the manual information that the widest filter needs to be first. It does not have to be in FL1 but it has to be first. I told her "THANKS I AM AWARE OF THAT"! How I did it I will never know but I proceeded to start with the wide filter in FL5 and then FL4, FL3, FL2 leaving FL1 open. Somehow in turning the board back and forth I messed up. What makes this more tricky than the filters on the main board of the K3? First of course the top shield soon covers your mistake. Secondly what make it even more tricky with the KRX3 the K3 only checks for correct filter placement in the main rig for the FLTX settings that affect the transmitter and mode (ERR TXF for example). In the SUB, it is solely up to you to get them right. Thirdly what really fooled me was I used the K3 utility and made changes to the KRX3 filters and changed things on FL1 in the KRX3 and sent them to the radio. I also set the filters up from the CONFIG setting so everything appears to be fine but in fact there was no filter at all in FL1 so the "ONLY" way to figure it out is to visually look at the filter placements. That is the only way to find this mistake in the KRX3 other than starting to trace the rcv signal which I was about ready to to. BTW Elecraft support has an excellent test procedure for this. The good news is when I pulled the top shield off I spotted the wrong filter placement instantly and just could not believe I made a stupid mistake like that. I took 4.5 hours with a break to put the KRX3 together and still made the mistake! I think when you know something you can easily become careless. I also got ERR VC4 E 00039 which required an adjustment of T1 windings on the sub synth board. Don't do this without instructions on how to do it. That problem was not my fault. It is just one of those things and was a real easy fix. Others have commented on the front panel removal! I concur it is not a big deal. The only thing that I would emphasize is when you put in the BNC for the Aux RF to note the instruction about "NOT" taking out the one screw. I dropped the stand off down in the radio and it took a lot of messing to get it out!!! After having the KRX3 board with the shield on in and out of the radio more times than I care to mention you eventually find you can get the cables routed quite nicely out of the way. At first it does not seem so but keep adjusting things as the cables can be placed so it comes in and out easily. BTW I was reading the KDVR3 manual and the front panel steps are basically the same as the KRX3 removal of the front panel. What a mad rush to get things working with the KRX3 on Thursday and then working right up until the 160 meter contest to get the two new bi-directional beverages hooked up and get everything interfaced to the K3 and try and learn how to use the RX antenna "AND" the sub-rcv "AND" diversity and provide some additional protection from RF getting into the radio. We had a whole 30 minutes to spare! Joe W0DB is operating here at W0SD and he has a lot of choices. It is so impressive what the K3 with the sub and with all the filters can do. The noise blanker also works the best of anything I have every used. The two best previously was the TR-4 years ago when mobile and the FT-1000B. Not only does it take out the noise it handles the strong signals with ease!!! I never seen anything like it. In this case for CW we are using the 500 hz and 200 hz on the main board and on the sub. Joe was down to 50 hz with the DSP and we still had QRM. Given I am told 50 hz is about the best you can do with your head the QRM on 160 meters in the contest is something to behold!!! I have had Collins line, Drake Line, ICOM, FT-1000D, TS-950SDX, etc. This is truly the greatest radio I have ever owned. With the KRX3 installed and the KXV3 the flexibility for antenna switching and diversity reception of signals is something not found anywhere. We have a switch so we can use the 7 rcv antennas either as rcv antennas to the RX in on the KXV3 or we can use them on the AUX RF in for the sub or sub using diversity.

[Elecraft] OT: [K3] Poor man's beverage and diversity
In preparation for a 160M contest one winter I took a 5000' reel of #22 ga insulated hook-up wire and tied the free end to a fence post. I then took off walking across the adjacent gold course and into the field beyond, the general direction of Japan while unspooling the wire behind me. The snow drifts kept the wire from laying completely on the ground, but at least there were no golf carts to snare it, and little likelihood of a stray snowmobile. (:-)) It worked well, but I now have a single turn hardline loop that does the tick just as well. Oh ... after the contest I reeled up back onto the reel and it's still in the barn. 73!

[Elecraft] [K3] Poor man's beverage and diversity
My 160-meter transmitting antenna is a 'T' -- an 88-foot dipole with open-wire feeders tied together and fed against some elevated radials running around the eaves of my house. The vertical part is about 40 feet (12.2m) high. I have always had the problem that this antenna picks up a huge amount of noise of all types. But I live on a lot that's about 50' x 120' in the middle of a city and there's very little room for additional antennas. A few minutes before the start of the ARRL 160m contest I decided to try something I'd heard about. I took about 180 feet (55m) of wire and laid it on the ground from my shack, across the backyard, around the back of my garage and all the way down the edge of the driveway. It turned out to be an excellent 160m receiving antenna! I expected that signals would be very weak, but they were almost as strong as on the transmitting antenna. My antenna analyzer showed an SWR of about 2.5:1. And, most important, the s/n ratio was much, much better. I connected it to the AUX input of the sub-receiver and activated diversity mode with a (very) long hold of the SUB button. I went to the CONFIG menu and set for SUB AF = BALANCE so that the sub's AF gain control would act as a balance control between the two receivers. This works great! I can hear signals get stronger in one ear when they QSB in the other. And for signals which come in better on one antenna than the other, I just turn the balance control. Even if you don't have a subreceiver, you should try the "poor man's beverage" (no, I don't mean wine in cardboard boxes) receiving antenna. Although the directivity is sort of arbitrary, the noise is way down compared to a vertical. The contest will still be going tonight. Try it, there is no antenna that is easier to install! -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Things to watch with the KRX3
Thanks for sharing these items Bill. I can add one to the list. Obviously most of us know that the widest filter we are using "HAS" to be first (lowest in number) slot. Somehow and I have no idea how I accidentally started at FL5 thinking it was FL1. Of course when you put the top shield on you can not you made a mistake. What makes it even more interesting there is no way to know they are wrong other than you don't hear anything as you do not get an error message with the KRX3. With filters in the wrong slot on the K3 main board you get an error message. Also the K3 software utility when you go to the KRX3 will show them as you put them in the software(it does not read the KRX3 configuration-it just writes to it and there is no indication anything is wrong. For example it appears you are making changes to FL1 which in my case there was no filter there. The only way to get it right is to visually see that you have the filters where they are supposed to be. Fortunately when I pulled the top shield off I immediately spotted my stupid mistake. On your last question if you hold down sub(longer than a tap) you toggle between link and unlink. However when you go to link if you hold the sub button in longer you see the word link and a bit later that is replaced by word diversity.

RE: [Elecraft] Doing all additions at once
You might "split the difference" on the hardware installs. The KDVR3 and Aux DSP board for the KRX3 require pulling the front panel assembly. Also, if you are planning to do the microphone grounding mod covered in the app note (to eliminate the "pin 1 problem") you can do them at the same time. Until you enable the KRX3 option, your K3 won't know the aux DSP board is installed, so you can check out your KDVR3 and any mods you've made after putting the front panel back on without the rest of the KRX3. Indeed, that's what we recommend kit builders do if they have the KRX3 on hand when assembling the basic kit. After you know the K3 is working properly with the front panel replaced, you can proceed with the rest of the KRX3 install and any other mods you have in mind, such as the "speaker amp" mod, etc., that are all done on the main part of the K3 and don't require pulling the front panel again. I agree with Don that the hardware installs are well understood and tested, as are the mods covered in the app notes. Firing up your K3 after working on the front panel assembly is just a nice way to confirm that nothing was amiss in the reassembly.

Reassembling and checking after each mod will reveal the first type problem, but it certainly will compound the likelihood that you will create a problem of the 2nd type. And doing the troubleshooting is mentally difficult because one usually associates the problem to the mod that was installed. Unlike software changes, these hardware changes have been installed by several users and the side effects (if any) are well known - it is not like making a change for the first time. My vote is to do them all at once, but YMMV depending on your confidence level. 73, Don W3FPR David Ferrington, M0XDF wrote: > I now have a lot of various extras and mods to add to my K3 - KRX3, > KDVR3, all the mods > - all because I haven't had the time or need to practice SMD or are > waiting for the last bits (some of which I've asked Elecraft to hold > so they ship as one) - all of which are going to arrive soon :-) > > It looks like there are some many dependancies on taking this off and > that apart, that it might be easier to do them all in one go - but > what are the risks of me missing something and then not being able to > figure out what that something is? > > In the software world, we never (should never) make multiple changes > without inter-step testing - but to test at each stage means putting > it back together again, using it bit and then taking it apart for the > next bit. > > What do people think here? > ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I have uploaded the rig control file I use to http://www.g4ilo.com/files/k3.xml . Download it, (you probably have to right-click the link and select Save As or your browser will try to open it) and save it as rig.xml. Open the file in notepad and change the com port settings so that they match your system (you will probably need to change at least the com port number.) Then move it to the place where Fldigi keeps its settings. On XP that is Documents and Settings//fldigi.files. In Fldigi itself, in the Rig Control settings, choose the RigCAT tab and tick "use RigCAT" and "use RigCAT PTT", then save the settings and restart the program. Hopefully that will get it going! I did send this file to W1HKJ as the K2 and K3 XML files you can download from there don't work, but he never put them on his web page. By the way, Fldigi for Windows 3.03 has an annoying bug, at least on my system, in that when you close it, it asserts RTS on the COM port (possibly DTR as well) and if you have the K3 PTT options set up to use one or other of those (perhaps because of some other software you use that does PTT using the control signals) then it puts the K3 into transmit on exit. So it is a good idea to set all the PTT options to OFF as well. I did report that issue to W1HKJ but it may have gone the same way as my XML file submission. - Julian, G4ILO.

[Elecraft] K3 and the digital modes
Thanks, For the many who responded to my question on hook-up for the K3 using the digital modes, THANKS. It works with MixW using the two cables from the in/out of the K3 to the mic/speaker on the computer along with a serial cable for rig control. Once I figured out that 'line in' had a gain control automatically selected when 'main/mic sel' was in the 'line in' position! It's where we normally adjust the mic gain control. Neat. I placed this in PF-1 memory which makes it easily to select when moving back and forth from digital to CW/SSB. And using the K3 at about 2.5 watts into a THP SS amp at 10/12 watts on the digital modes, everything runs very cool. It's a learning process but with good help here on the reflector, it was possible and again thanks for the thoughtful help. Side bar: The dual PB feature for CW is great and thanks to Ralph, K1ZZI/4 for calling that to my attention. I still can't believe all the goodies this rig has.

Re: [Elecraft] Doing all additions at once
Thank you Don, I'm aware of your considerable experience with all things Elecraft and will take your valued advice - it will be easier that way anyway.

Which kind of band decoder are you using? How did you connect your K3 with the 2KL? I guess with a single cable from the key out (K3) to the T/R control terminal, right? I´m a bit scared of harming the K3 or 2KL, because of wrong connections. Is there anything else I have to think of? I´m also using the AT 500 tuner and I sometimes have problems too. Sometimes the tuner does not want to tune at all, so I use a little trick. I engage the internal IC 761 tuner and then the AT500 starts tuning. I turn the internal tuner off and everything works fine. 73, Chris-OE5CSP -- Pt! Schon vom neuen GMX MultiMessenger gehört?

[Elecraft] Doing all additions at once
I now have a lot of various extras and mods to add to my K3 - KRX3, KDVR3, all the mods - all because I haven't had the time or need to practice SMD or are waiting for the last bits (some of which I've asked Elecraft to hold so they ship as one) - all of which are going to arrive soon :-) It looks like there are some many dependancies on taking this off and that apart, that it might be easier to do them all in one go - but what are the risks of me missing something and then not being able to figure out what that something is?
