[Elecraft] A K3 filter observation
K0PP: Mine has 6, 2.8, 2.1, 1 and .4 kHz 8-pole roofing filters. It's amazing that I can move from the widest to the narrowest filter with a twirl of the Width control while tuned to a CW signal ... using the NEAT CWT feature ... and not hear any sign that I've (actually, the radio) has switched through five filters. There is -NO- ringing. Impressive! There is definitely a little ringing in the 50 Hz DSP setting...as there should be. I haven't yet measured the DSP BWs but I have a feeling Elecraft's WIDTH settings are accurate at the low end, unlike Ten-Tec or Icom, who tend to overstate DSP filter performance. I recall Orion's 100 Hz is actually more like 150 Hz, and the 756 Pro family's 50 Hz is more like 80 Hz. When you hear someone say I have no ringing at 50 Hz, it probably means the filter BW is actually NOT what the radio says it is. So far the K3 impresses me as a radio designed by engineers...and not marketeers. 73, Bill W4ZV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Powerpole connector issue!
Guys, I built SN # 104 up in about 4 hours to the 10 watt version (I have not yet fitted the 100 watt PA), it went together so easily I was slightly disappointed that it was not more involved!!! Joking aside the only (and I mean only) issue I have had was with the main board mounted powerpole connectors! When unwrapped the main PCB looked fine but upon assembly I noticed a slight misalignment (around 0.75 mm) of the Red (positive) PP connector, it was shorter than the Black (negative) one! I nevertheless continued to build up the rig until it was completed then I noticed when connecting the power lead for initial testing that the mating up of the connectors was not very positive (i.e. secure). Upon investigation I found that the internal metal connector was 1.5 mm short from being fully home in the board mounted housing!!! Yesterday I partially dismantled the rig and removed both board mounted connectors and rebuilt them correctly. When reassembled everything was fine, this is the only issue I had with the kit but I must say that whoever fitted the Powerpole connectors on my main PCB should have had their arse (ass) kicked! The wire was poorly tinned and badly aligned, still... It made it more of a kit for me and let me use the soldering iron a bit more than intended so no harm done ;-) 73's Vic Tuff G7PYR K3 SN #104 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] FILTER SETTINGS
W4TV: However, the 250 Hz filter is actually 370 Hz at the - 6dB points according to previous e-mail here. With the K3, the point of diminishing returns for IMD (and close in rejection) is perhaps - 30dB instead of -60dB or more in a conventional crystal filter only radio. If we use a straight line (linear slope) from the -6dB to -60dB points the 200 and 250 Hz filters look like this: 200 250 - - 6dB 224 Hz370 Hz -60dB 896 Hz777 Hz slope 6.22 Hz/dB3.77 Hz/dB (one side) -10dB 274 Hz400 Hz -20dB 398 Hz475 Hz -30dB 522 Hz550 Hz -40dB 647 Hz626 Hz -50dB 771 Hz702 Hz By this simple calculation (or by plotting on graph paper) one can see that the 200 Hz filter should do a BETTER job as the most narrow filter. It remains tighter to about -35 dB and the five pole design should result in less pulse stretching (ringing in the presence of static) than the 250 (really 350 Hz) filter. Excellent post Joe (as usual). Another reason one might want the 200 versus the 250 is the relative difference between the 400 and 500 filters. From the published data: Filter BW(-6dB) Shape Factor 200 224 4.0 250 370 2.1 400 435 2.1 500 565 3.1 Practically there is little BW difference in the 250 and 400 8-pole filters. If one wanted both a very narrow and moderately narrow filter, I would choose the 500 and 200 5-pole filters. They have at least an octave difference in total bandwidth...plus the group delay issues you cited in your last paragraph above. BTW I see very little insertion loss in either of the 200 Hz or 500 Hz filters. Using an XG1 source, I find 1 dB compensation is all that is needed for both. 73, Bill W4ZV P.S. I retract my engineers vs marketeers statement. The marketeers won in naming the filters, especially calling the 370 Hz filter above a 250 Hz! :-) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Aptos / vendor soldering
Since the PowerPole soldering issue was raised . I found the short black jumper wires soldered to the two antenna connector SO-239's were poorly done. Both had about 3/8 of exposed center conductor soldered into the connectors and at an angle. No matter though ... I replaced both with lovely BNC SO-239 replacement kits from Oak Hills Research. I use Pomona BNC patch cords for almost everything here and so the change was a natural. I did rework the male pin ends of the two wires and added shrink tubing over the solder connections on both ends of the wires Maybe this is the first after market mod to a K3.

[Elecraft] K3 - UHF/BNC
No matter though ... I replaced both with lovely BNC SO-239 replacement kits from Oak Hills Research. Well done, Ken! That is the one mod I was planning for my K3 when it arrives in Feb. I was planning to make just one aluminum panel piece and mount it to the S0-239 mounting holes and use two BNC bulkheads in it. I was unaware that Oak Hills had pre-made fittings for this. Using two of these is certainly an option if I don't want to do the cutting/drilling. Thanks for the tip - it had been awhile since I looked at the Oak Hills website. By the way, everything here in the shack and test bench is also all BNC. I never understood the attraction of UHF connectors. To me they seem large, cumbersome and aggravating. Glad I don't know how much $ I have spent in UHF/BNC adapters over the years ;) ...

Re: [Elecraft] K3 - Come on Simon...
Hi All, Now, you do have to admit that Fred has something of a point here. Rarely does a missing apostrophe leave the reader completely confused as to the meaning. I tend to be somewhat fanatical about the english language myself, but I do sympathize with his position. I am somewhat anal about usage of the comma. My english teachers drummed comma fault into my head to the point where I often get obsessive about re-reading things to be sure I haven't committed the ultimate sin and left out a comma. I'm sure it causes me to put commas into a sentence that need not be there. It doesn't surprise me that the brits have a society to preserve the apostrophe. They claim full rights and privileges over the language, and are often pretty critical of how we have bastardized the language here in the colonies. Unfortunately, in many cases they are right. But, as I often tell my brit friends, You are the masters of excess! Look at all those vowels they insert which are completely unnecessary in my opinion. Labour instead of Labor, honour instead of honor, etc. It's beyond me why they don't take all those unnecessary vowels and, in the interest of conservation and good will, donate them to some place like Poland where vowels are sorely lacking! Another place in need is Wales. Anyway, back to Fred's problem. I think a compromise is in order, and I have a suggestion--one with which probably nobody will be happy. But here it is anyway. If you truly feel that inserting an apostrophe midstream in a word like don't is a pain in the neck, why not just wait until your message is finished and tack on a bunch of apostrophes at the end. Then the reader, if so inclined, can go back and insert them as necessary. After all, if they know when one is missing, then they will know where to put them! But, in fairness, if you opt to do it this way, you need to make sure you put just the correct number of apostrophes at the end. After all, you don't want to drive people nuts trying to find where to put some extra apostrophe you might have tacked on (or do you)! It also helps to assure us that you really did know better, and just didn't want to take the time to insert them along the way. It sort of makes a game out of it. Actually, it's already a game of sorts trying to interpret some of these emails with all the missing or misspelled words, etc. But this gives the game a little structure. What do you think?

[Elecraft] Reed Prince
It is Reed and Prince, not Reid and Prince...The Reed and Prince company has been in business in Massachusetts for over 120 years...They started out making nails...The cross-head Reed and Prince screw goes back to the 1930's and preceded Phillips... The Reed and Prince screw driver was designed for production work...Because of the sharp point, one size fits all, making it unnecessary to change tips on the production line...Many screw drivers sold today as Phillips are not really Phillips because they have a sharp point, a characteristic of Reed and Prince...Phillips drivers have a blunt point and it is necessary to change tips to accommodate the size screw...If a Reed and Prince tip is used on a Phillips screw, the pointed tip will bottom out in the shallow recess of the Phillips screw, preventing the side flutes of the tip from fully engaging the cross slots, possibly resulting in stripping out the cross slot...Examination of the recess in the screw will tell if it is a Phillips or a Reed and Prince...The Phillips will have a shallow, almost flat bottom, the Reed and Prince will be deeper and have a pointed bottom... I prefer Apex drivers because many different tips (straight slot, Phillips, Allen, Torx, etc) are available...They use a 1/4 hex drive on the back of the tips that plug into a socket in the driver handle...They are hard and brittle and will chip if over-torqued, but they will not round over, which causes slipping...

RE: [Elecraft] FILTER SETTINGS
Bill, By this simple calculation (or by plotting on graph paper) one can see that the 200 Hz filter should do a BETTER job as the most narrow filter. It remains tighter to about -35 dB and the five pole design should result in less pulse stretching (ringing in the presence of static) than the 250 (really 350 Hz) filter. Excellent post Joe (as usual). Another reason one might want the 200 versus the 250 is the relative difference between the 400 and 500 filters. From the published data: Filter BW(-6dB) Shape Factor 200 224 4.0 250 370 2.1 400 435 2.1 500 565 3.1 Practically there is little BW difference in the 250 and 400 8-pole filters. If one wanted both a very narrow and moderately narrow filter, I would choose the 500 and 200 5-pole filters. They have at least an octave difference in total bandwidth...plus the group delay issues you cited in your last paragraph above. Expanding the 200/250 analysis to 200/250/400/500 as I did privately for someone else: 200 250 400 500 - - 6dB 224 370 435 565 Hz -60dB 896 777 913 1751 Hz slope 6.22 3.774.4310.98 Hz/dB -10dB 274 400 470 653 Hz -20dB 398 475 559 873 Hz -30dB 522 550 647 1092 Hz -40dB 647 626 736 1312 Hz -50dB 771 702 825 1531 Hz I really think the 200/500 pair is the best value. The only possible benefit of the 400 over the 500 would be an improvement of 500 Hz spaced IMD. However, as you have pointed out, with strong interfering signals at 500Hz and 1 KHz, the problem is far more likely to be radiated phase noise and clicks from those signals than receiver generated IMD. I'm looking forward to information on the variable CW filter, something like a 400 Hz to 1 KHz range would be ideal in place of either the 400 or 500 Hz filter. 73, ...

Re: [Elecraft] K3 - SWR Fold-back
I don't know if this will help, but I've had two experiences with my K3 regarding power reduction. While attempting to participate in the 160M contest, I connected to my 80M dipole and hit tune in the ATU active mode. I immediately got a high SWR and retune cycle which reduced the SWR at the rig to ~ 10:1. Checking the power output, which had been set at 106W, it was indicating 79W. During a second subsequent tune (same ant and same settings ) the rig initiated a tune cycle and immediately shut down. No overpower/high current indication. I turned the rig on again, and everything was the same as before. I suspect maybe the tune was marginal and that at that SWR the rig is between a 'continue or shutdown' logic process. No residual effects were noted.

Re: [Elecraft] FILTER SETTINGS - Correction
That's where the better shape factor hits home. For the 1 kHz filter, with -30dB BW of 1400 Hz, we have adequate rejection at 1400/2 = 700 Hz, versus the 5-pole 500 Hz at 1092/2 = 546 Hz, a difference of only 154 from the center frequency. Not a bad single filter choice for for CW ops like me who aren't serious contesters, and are interested in using the context filter.

[Elecraft] K2 Transmitter Power Issue
K2 s/n 4276 Firmware Revision(s): 2.04P 1.09 I am having a problem with output power stability. Example: Power set to 5 watts.

RE: [Elecraft] K3: CQ sn# 129 to 142
Better yet, instead of collecting S/N's in an attempt to guesstimate what shipped last week, how about a weekly shipping status update? Please Elecraft; enlighten those of us who are in the 1st batch and waiting. It would be far better if Elecraft would divide the backlog into groups of 10 to 25 radios (they don't need to tell anyone how many in each group) and notify each customer into which group their order falls. The each week, they can post which group or groups are targeted for shipment in the next couple of weeks. For example, the shipping status might say: during the week of 17 Dec kits in group 14 and 15 and assembled radios in group 13 are expected to ship. There will be limited shipments during the weeks of 24 Dec and 31 Dec. Normal shipping levels will resume the week of 6 Jan. This would provide better visibility for the customer who is waiting (im)patiently without releasing too much information. 73, ...

[Elecraft] K2 s/n 6322 is assembled and working!
Hi Everyone, I just thought I should send a quick update and let everyone know that my new K2, serial number 006322, is now up and running! The antenna tuner, SSB adapter, and noise blanker are installed and working. The power supply for the moment is a 12 volt, 7 amp-hour battery that I connect with some alligator clips; not fancy, but seems to work just fine. I also have the internal battery for the K2 on order which should arrive today. The only thing I haven't put together yet is the I/O module, which I don't plan to put together right away; I want to learn how to use what I have first! The antenna I'm using at the moment is very random wire; it's about eighty feet of wire run a few inches from the ceiling, starting in the work room (sewing room/computer room/electronics lab/etc) wandering around the room, down the hall, and around the living room. It looks terrible, in my opinion, but works ok for now. The two things that seemed to help were having quite a lot of wire, and getting close to the ceiling, which I suspect is not backed by chicken wire or some other faraday-cage-style nuisance. I'll probably try to experiment with some other antenna ideas but there just aren't all that many possibilities for an external antenna in my current location; even stealth antennas are kind of iffy due to various circumstances. My random-ugly-wire seems to tune up pretty well, I think; it seems to manage SWR's in the 1.something:1 range most of the time. I've heard clear, strong signals on 80m, 40m, and 20m, so I'm pretty sure the radio is working now! I also discovered why I couldn't hear anything on 40m when I first tried it out... the culprit turns out to be my gigabit ethernet switch and/or it's accompanying wall wart! With that disconnected, I have a perfectly nice radio, but when I plug in the switch, I have a very expensive buzzing machine instead! Pretty much all the bands are blanked out by the noise! Fortunately the gigabit switch isn't critical at the moment so I've just left it unplugged, and I'll deal with it later. There's still quite a lot of noise from the other apartments in the complex, and a tiny bit from my other network equipment, but nothing unmanageable. I've also ordered the Buddistick vertical from Elecraft, along with the tripod; my hope being that I can use that to easily operate in the field, which, if nothing else, would get me out of the house a little more! :-) And speaking of operating in the field... it looks like I may get to take a vacation starting next week, which is something, strangely enough, that I've never really done! My last real vacation was 20+ years ago when I was still in school, so taking time off to go on an adventure is a new thing for me, really! I'm thinking about just getting in the car and heading North from San Diego, towards Northern California, or maybe Oregon or Washington, but without any particular set plan. I'm of course thinking of bringing my K2 with me, so if anybody has any travel tips, K2 specific or otherwise, I'd welcome the advice! At the moment I still don't have a microphone or a code key (or code skills), so I haven't actually been communicating with anyone yet... I'm working on that! Right now there's still a lot to learn from just listening! It's quite a lot more exciting to hear a real HF radio signal than to just read about it! Yesterday I heard people calling from Vancouver Island to Monterrey, Mexico, and several other nearby states... it was a lot of fun! Thanks for your help, everyone!

Re: [Elecraft] K2 Transmitter Power Issue
William, Check the soldering carefully, particularly on the Control Board. Also check and re-check the placement of the components mounted on the back of the Control Board (they are part of the power control circuits). Check soldering, then re-check the soldering, and when that is finished, check the soldering. Good luck in finding it. 73, Don W3FPR kc4wvl wrote: K2 s/n 4276 Firmware Revision(s): 2.04P 1.09 I am having a problem with output power stability. Example: Power set to 5 watts.

Wiped away excess, especially in the area of the slats in the metal. I don't want excess to appear on the outside of the radio. * placed the speaker cloth on the contact cement, covering the speaker mounting holes, and allowed cement to dry. * With a small soldering iron, hot, poked out the screw holes by melting the fabric with the hot tip * mounted speaker. Cloth is not free to vibrate, but will serve its purpose of protecting the speaker from debris and intrusion through the gaps in the metal. 73, Fred K2 # 0700 K3 # 0144 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Final Photos Added (Link)
Brian, Problem: Receive was intermittent, transmit was no output along with ERR TxG. Turned out that it was the chip resistor providing voltage to VCO amplifier Q3 in the synthesizer. One end of the resistor hadn't reflowed right (solder hadn't wicked up the end), and it was open circuit, even though it looked OK. Even under strong magnification it wasn't obvious. So the synthesizer usually wasn't putting out enough for the mixer. The mixer would work sometimes, then sometimes not. One touch of the soldering iron, and the VCO output was up over a volt, and the mixer was happy. Credit and thanks to Gary, and finally to Wayne, for helping me track this one down.

RE: [Elecraft] K3 f/w updates and Keyspan USB to serial port adapter
John, I just loaded my K3's firmware successfully with a Keyspan USA-19H USB Serial Adapter. I used a Sony Vaio VGN-FZ150E laptop with Windows Vista. I first installed device drivers from the Keyspan web site. However the Keyspan USA-19H I have here has a 3' cable, and the fasteners on the DB-9 connector are nuts, so it won't mate with the back of the K3, which also has nuts. You'll need a M-F serial cable with screw connectors on each end. This fastener gender issue is pretty common with USB adapters; the only one I've seen that mates correctly (has screws on the DB-9 end) is the KUSB sold by Elecraft. There may be others, I just haven't seen them. For me a 6' serial extension cord is not an issue at all, so it doesn't matter that much to me.

Re: [Elecraft] K3 f/w updates and Keyspan USB to serial port adapter
Hi Dick, I have a serial m-f straight-through cable that has screws on both DB-9s. However, I see from the picture of the K3 rear panel that the RS232 connector is male. I looked at my Keyspan USA 19HS adapter and found that it is also male. So to make it work I would need a f-f serial cable. I think that I should order a KUSB, which is exactly what I was trying to determine. I appreciate yours and everyone's help with this.

Re: [Elecraft] New K3 f/w: MCU 1.48, DSP 1.45 and new Downloader version available
* Noise reduction much improved, including insertion loss compensation. Can you offer a little more information about the NR? In this version of NR, the set levels are in four groups of four, whereas previous versions have been 0 to 39 or 0 to 3. Additionally, I noticed that the NR does not appear to work below BW of 500Hz. Is that true or am I just not noticing the effect? NR continues to evolve. The latest version, as you noted, has four settings for each of four groups. The lowest numbered setting in each group is the gentlest, while the highest setting in each group offers more noise reduction but slower response. If find for SSB use that I usually use the 2nd setting [ NR F1-2 or NR F2-2 ]. The F4 group can have a sort of hollow sound for voice under some conditions, but is excellent for narrow modes like CW. Below a width of about 500 Hz, NR is disabled in the current release. We have more code we are testing now that allows its use down to the nominal 50 Hz wide filters in CW mode. If testing goes well, it will be released in due time. Even more exciting, we are also testing... oops, I'd better not say! 73, Lyle kK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 firmware loading
Hi Buck, We had an incorrect file uploaded to the FTP site for a few minutes that may have impacted your load. I suggest you delete all files from your local load folder, then re-download all the files from the FTP site. When the K3 displays MCU LD, it has failed its checksum test and is waiting for new code from the loader. If you're unable to load after getting the files again, please send an e-mail to [EMAIL PROTECTED] and someone will help you. Note that you also must use the latest version of the downloader (K3 Utility). 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 KUSB option
The KUSB is a USB to Serial Port adapter, a cable that has a USB connector on the computer end and a 9-pin RS-232 connector on the K3 end. The KUSB is similar to other USB to Serial Adapters on the market. Some USB to Serial Adapters have nuts rather than screws on the DB-9 connector. The K3's RS-232 connector has jack nuts, and some USB to Serial Adapters won't mate easily unless you remove the nuts from the adapter, and that's not always easy. The KUSB has screws that fasten to the K3's RS-232 connector. The KUSB is 6' long, and some USB to Serial adapters are a bit shorter. I test with a variety of USB to Serial Adapters, including the KUSB, and I'm using an extension serial cable that has screws on each end. The K3 has a 9-pin RS-232 connector. It does not have a USB connector.
