[Elecraft] K3 - mounting the front panel
I have found the following procedure gives me time and support to do this easily: 1) Remove right side panel (probably off already if you're working on the front). 2) Remove the rear mounting screw on the 2-D fastener, front right of RF board 3) Lay the K3 on its right side, on a smooth anti-static surface. 4) Lay the front panel on its right edge and cozy it up to the K3. 5) Be sure the front dress panel comes inside the left side panel. 6) Be sure the front dress panel overlaps the 2-D connectors correctly. 7) Check connector alignment and mate the front panel slowly, while everything is on its side. Since the table carries all the weight, your toper's hands will not have a chance to louse things up! As always, YMMV.

For weak signals the additional bandwidth gives my ears a better context in which to apply my ear/brain's internal 50 Hz filter. In contests, I also want to be able to hear stations calling me off-frequency as well as hear what's going on around my run frequency (so I can chase off those folks who send "?" once and then start CQ-ing 250 Hz above me). I would actually prefer 8-pole filters for rejection reasons, but the bandwidth choices above are simply wrong for my use. The 400 is too narrow and the 250 is too wide (and only 65 Hz between the two!). When I need a narrow filter, I want a *truly* narrow filter. The main use I have for the 200 is in nearly simplex pileups with lots of S9+++ signals (think 160m DX pileups). Another reason one might want 8-poles is when using N8LP's LP-PAN and SDR software for a panadaptor/waterfall display. The 5-pole offsets can cause a similar problem here as you rotate WIDTH through different filters. However, with the recent addition of Elecraft's programming commands to read the internal filter offsets, N8LP says WU2X can correct for the offsets in his PowerSDR-IF software. The bottom line to me is that I choose filters primarily for their bandwidth and I prefer the 500/200 combination even with their offset warts. If Elecraft offered different BW choices in the 8-poles, I might prefer them. Quite frankly, given the current $25 price differential, I don't see why Elecraft doesn't go to all 8-pole filters and make some better bandwidth choices (e.g. at least octave differences at the low end...say 600 and a *true* 250...not the one above which is actually 370).

Re: [Elecraft] K3: KRX3 question
Hi Bill, If you worked RTTY you would find out that the "250Hz" filter is ideal for recovering weak ones and for 20M during RTTY contests. The dual passband filter fits very nicely within it. I don't care what bandwidth you call it. Don't eliminate it as a choice. I was astounded the difference it made during yesterdays DL RTTY contest. Fine tuning + the selectivitiy made the 20 KHz RTTY band seem like 100KHz wide while doing search and pounce. A/B comparisons between it and the 400Hz filter did indeed show significant benefit. Spectrogram spectra, with a band loaded with signals, strengthen this A/B comparions conclusion. Some offending signals simply fell off the edge of the 250 Hz filter slope. Part of this benefit is undoubtedly due to the capture effect of FM like modes. Strongest wins. 73 de Brian/K3KO Bill W4ZV wrote: Brett Howard wrote: So am I to assume that the 8-pole filters are not going to need to worry about this as they are all at 0 anyway?

[Elecraft] Vox and PSK31
Everyone, There is a definite downside using VOX to control your rig when using computer sound card digital commumication software. To discover this downside just monitor 14,070 for a period of time while the band is open. You will hear many of the Windows sound chimes or warnings. It is too easy to forget your rig is on, in the VOX mode while you are working with other programs in Windows. 73 Dave KD1NA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3: KRX3 question
I think I must be missing something. As I understand it, the additional crystal filters are only really necessary when operating with very strong adjacent signals in the passband. So, if you don't have a need for rejection of such strong signals, let's say >40 over S9 (somebody correct this figure please) then you don't need these extra filters, the DSP will cope with these large signals. The filters are only there to prevent overload of the DSP. Therefore, to perform the very best diversity reception in <40 over S9 conditions, turn off those extra filters in configuration menu. Having turned off the filters, I can engage the attenuator to avoid DSP overload if needed. Yes, I know it also reduces the signal I'm trying to hear, but that sacrifice may be what is needed. For diversity reception using low gain loop, pennant, flag, Beverage, loaded whip antennas, the signal input is very much lower than from the tx antenna, so, crystal filters are probably not be needed at all. Or do I have it all completely wrong? David G3UNA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] CORRECTION: K3 - mounting the front panel
While dalking my wog my senses reverted and I remembered that "right" should have been "left" in the following. Sorry for the bandwidth and confusion. I have found the following procedure gives me time and support to do this easily: 1) Remove left side panel, the one with the handle (probably off already if you're working on the front). 2) Remove the rear mounting screw on the 2-D fastener, left front of RF board, behind mic connector. 3) Lay the K3 on its left side, on a smooth anti-static surface. 4) Lay the front panel on its left edge and cozy it up to the K3. 5) Be sure the front dress panel comes inside the right side panel. 6) Be sure the front dress panel overlaps the 2-D connectors correctly. 7) Check connector alignment and mate the front panel slowly, while everything is on its side. Since the surface carries all the weight, your toper's hands will not have a chance to louse things up! As always, YMMV. Works for me. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] KRX-3 R-19
Steve, I believe you meant R91. This resistor is *only* to be added if the measured value of R91 is about 100 ohms. Many later K3s already have it changed to 22 ohms, and on those the resistor should *not* be added. The KRX3 manual makes it clear that one should measure R19 with a DMM and add the 27 ohm resistor only if the measured value is in the vicinity of 100 ohms. Elecraft's instruction manuals are written to cover installation in all K3s no matter whether early or late serial numbers. I believe the DMM check method is a more reliable way of determining whether the resistor needs to be added than any reference to a serial number. As an added trivia note - Elecraft does not use dashes in either product numbers or part designations. That is left for the manufacturers who want to bring out an updated version of the radio with a different model number. Elecraft radios are fully upgradable for the entire life of the product and upgrade kits are provided. As a result, there is no such animal as a KRX-3 or R-19 in the Elecraft world. The only exceptions are the N-gen and 2T-gen mini modules. I believe those were named by someone other than Wayne or Eric. 73, Don W3FPR W0SZ wrote: I was wondering if anyone knows if R-19 will need to be modified in all K-3s or is there a serial number where the value for R-19 was changed.

Re: [Elecraft] K3: KRX3 question
David, In most instances, you are correct. My K3 has only the stock 2.7 filter, but then I am not into heavy contesting nor intense DX chasing - I do some contesting and work DX for fun only. When it gets to the point where I really need narrow roofing filters, it is time for me to go listen to some relaxing music, so you will not find me using diversity reception to pull out some obscure weak signal. One related point - the Hardware AGC should prevent overload of the DSP, so the K3 will handle those strong signals nicely. The problem is that the AGC action when a strong unwanted signal is within the roofing filter passband, the AGC will reduce the sensitivity of the entire receiver, so your wanted signal gets weaker too - and you may not even know the offending signal is there if you have the DSP bandwidth at a narrow width - it will behave as though there is QSB on the signal you are listening to. Of course using diversity reception with one antenna having lower gain, that QSB effect may be minimized. 73, Don W3FPR David Cutter wrote: I think I must be missing something.

Part of this benefit is undoubtedly due to the > capture effect of FM like modes. Strongest wins. What DSP bandwidths were you using and where did you have your crystal filters engaging? There is only a 65 Hz bandwidth difference between the "400" and "250" crystal filters and both are wider than the what is needed for 170 Hz shift RTTY. The crystal filter function is to protect the DSP from strong nearby signals and a 65 Hz delta is irrelevant at 400 Hz. So there will NOT be any discernible benefit on RTTY or any other mode if you do the A/B comparison with the same DSP bandwidth (with or without the DTF). For example, if your 400 Hz filter engages at DSP bandwidth of 400 Hz and your 250 Hz filter engages at 250 Hz, then you are really A/B comparing DSP bandwidths of 400 and 250 Hz, not the crystal filter differences. What can make a difference in large RTTY pileups is running the DSP down as low as 200 Hz which rolls off the outer edges of the tones, but eliminates enough of the pileup to sometimes be a net advantage. In general, running the DSP at 300 Hz with the DTF engaged is ideal for 170 Hz shift RTTY because there is little roll off of the desired passband. Of course, the 250 Hz DSP bandwidth is a step between these two settings and also a viable alternative in some situations. The "250 Hz" crystal filter at an actual -6 dB bandwidth of 370 Hz is a good roofer for these three DSP bandwidths, but the "400 Hz" crystal filter at an actual BW of 435 Hz is essentially the same as far as protecting the DSP from nearby strong signals. 73, Ed - W0YK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3: KRX3 question
I sense that a fair amount of folks view K3 crystal filters in the traditional sense, for example the "need" for a 500hz filter on if one is going to operate CW. This ia a long way from the truth with K3. Same thing for the 1.8khz filter, unless you're having antennas that bring in contest strength signals, not necessary at all. Buck can probably comment on this, I never owned Orion, but it seems they never had the ability for a roofing filter on the second receiver and if you put K3's receiver or subreceiver head to head without a roofing filter (DSP only), the Orion receiver would suffer AGC pumping terribly since it's default roofing filter is at more than 10 khz and K3 is at 2.7khz. That's what my Argo V did. The point is, the stock K3 setup is majorly robust for either the main receiver or the subRx in stock form.

However, if you use DXLab Suite or similar programs with DX alerting functions ... or use the PC for any other purpose ... a second sound card is still a "must have."

If you are planning to operate from a fixed location, you will get much better performance from a wire antenna mounted as high as possible, and such an antenna would be much cheaper. In the field, a Buddipole would be especially good if you can locate it next to a sharp dropoff, which would compensate for the low height. A Buddistick would be especially good on a beachfront or other salt-water location, but relatively poor in the mountains where ground conductivity is not so good.

G'day, Interested in what power level is required to trigger the carrier operated relay in the KRX3. Just out of interest I've checked the coupling between my OB9-5 and the OB5-6 about 2.4 metres above it, booms in-line. 900W into the HF coax, terminated WM-2 on the 6M coax. worst case 45mW on 21250kHz. Same test but looking at the pickup on the 40M coax, 5mW. Regards, Mike VP8NO ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 - setting the AGC threshold
Johnny, All will be OK if you just set it to maximum. The cause is the 8 volt regulator is on the low end of its tolerance range. You could replace the regulator to being it up, but you will not notice any difference in the K2 nor its performance. If you wish to increase the AGC Threshold voltage without changing the regulator, you can solder a resistor across pins 3 and 4 of RP6 - you may have to experiment a bit with the value until you can obtain a bit greater than 3.8 volts from the AGC Threshold pot adjustment, I would recommend starting with 15k and work from there. Be aware that there is a note in the manual instructions for Setting the AGC Threshold which states that "This is the suggested setting, but it can be adjusted later to suit the operator". Any setting that will improve the sensitivity of the K2 will be lower than 3.8 volts. If the AGC Threshold is set too low (below 3.65 volts or so), the S-meter adjustments get a bit tedious if one is picky about the low end reading, the high end reading and the S-9 reading with a 50 uV input signal. All 3 conditions can usually only be met with an AGC Threshold voltage in the 3.7 to 3.8 volt range. 73, Don W3FPR Johnny Siu wrote: > Hello Group, > > Although I built a lot of K2 in the past, I encountered problem nearly each > time.

Re: [Elecraft] Band button
I think there is a misunderstanding of the meaning of the word "Band". The higher bands for example refer to the bands in terms of frequency. The 20m band is in terms of wavelength. However, no bands are officially described in terms of wavelength any more. Not since 150m and down! Look at all band plans - even the USA one - and you will find it is defined by frequency. So, the K3 and all other radios are correct. Mike K3KO wrote: > > This isn't just the K3. Other radios have the same problem.

[Elecraft] KRX3- K3 R91
I am waiting on my KRX3 (backordered since July '07) but decided to check my K3 for the value of R91. My K3 s/n 559 had 100 ohms for R91. I removed the existing 0603 sized resistor and replaced it with an 0805 size 22 ohms that I had on-hand. (The method I usually employ for resistors and caps is to use two soldering irons, one in each hand. Observing through an Opti-visor, heat both ends of the component simultaeously, and gently lift it off the board.)The pads on the PC board are large enough to allow the used of the 0805 component. I had no difficulty performing this mod. I look forward to installing the KRX3 once it arrives. 73, Bruce N1RX ___ 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: KRX3 question
I find that the narrower filters take out a lot of the noise before it hits the DSP and it can even make just rag chew conditions nicer in my very electrically noisy area. Actually I'm quite excited that once I get my K3 back that I can set the 250Hz filter to be able to use it up at 350. I even am adding the 1Khz filter as the step in the noise when switching from my 250Hz to my 1.8Khz was pretty large. Honestly I'm not so sure that the 1.8 is really all that much of a help over the 2.7 but the 250 is a big help over the 2.7 and the 1.8. Plus I just like having the radio do all the intelligent rock switching. Makes it a very nice combination and mixing of the old way of doing things and the new way of doing things.

The KAT100 will match almost anything, but an odd number of quarter-wavelengths will produce a reasonable impedance for a random wire antenna with less likelihood of making the radio 'hot' for RF. Then you should also attach a counterpoise to the ground terminal; this could be 16 ft (5M) or so of wire thrown on the ground. You might get better results with a dipole, but this is about the simplest antenna there is and it will probably work better than small loaded verticals, etc. -- 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] K2 --- Park Portable Antenna
As Vic pointed out, a center fed half wave (i.e. center fed "dipole") is probably the most efficient and easiest to erect, especially on 20 meters where it's only 32 feet end-to-end. Such an antenna provides a low impedance, letting you use coaxial feeder if you use a feed line. Keep in mind that it does *not* need to be in a straight line. It can be erected in various ways. For example, if you throw one end over a tree so it drops vertically to the rig, the other half can run horizontally near the ground, making a very efficient "vertical". Such an arrangement will be somewhat directive in the direction you run the horizontal segment near the ground. Optionally you can use feed line and make an inverted "V" Skip the coax and use a reasonable length of 300 or 450 ohm window line for a feeder (just hook one side of the twin lead to the center pin on the antenna jack and the other side to the chassis ground) and you can use the antenna on any band from 40 through 10. On 40, where it's only 1/4 wavelength overall, it'll be 1 or 2 dB "weaker" than a full half wave, but that's pretty darn good. On higher frequencies you'll actually see a little "gain". .

Re: [Elecraft] k3 fan noise
You're right that it is uncommon. Properly installed, the fans are completely inaudible. I believe all the instances where fan noise has been encountered were traced down to some kind of assembly error. Probably Don could point you in the right direction.

[Elecraft] Elecraft CW Net Report for July 6th & 7th, 2008
Good Evening, Forty meters got so bad I had to quit. I know there was one more station, W??O?, but I could not drag him out of the noise. The QSB was eating most of his signal which was not covered up by the QRN. Very tough copy but I am sorry I missed you :( Twenty meters was a little noisy but nothing like what forty became near the end of the net. There was a little QSB on twenty meters but once again nothing like it was on forty meters. At first I thought forty was going to be better than twenty but gradually it deteriorated. On to the lists => On 14050 kHz at 2300z: WB3AAL - Ron - PA - K2 - 1392 NK6A - Don - CA - K2 - 1217 W6ZH - Pete - CA - K2 - 5138 * QNI #125 * W0JFR - John - CO - K3 - 994 K1THP - Dave - CT - K3 - 686 W0RSR - Mike - CO - K2 - 5767 K6DGW - Fred - CA - K3 - 642 K6PJV - Dale - CA - K3 - 1183 K9DMV - Joe - IL - K2 - 5628 N0AR - Scott - MN - K2 - 4866 AH6RE - Curt - HI - K3 - 469 KL7CW - Rick - AK - KX1 - 798 N7KRT - Jeff - TX - K2 - 5471 WS7L - Carl - OR - K3 - 486 N7AF - Dave - AZ - K2 - 4795 NF8J - Paul - MI - K3 - 758 On 7044.5 kHz at 0200z: AH6RE - Curt - HI - K3 - 469 W6ZH - Pete - CA - K3 - 657 W0JFR - John - CO - K3 - 994QNI #45!!!

Re: [Elecraft] Band button
Isn't there some authorized amateur activity in the 600 meter band? I saw someone post that they had a beacon going aroun 500 khz.

Going to a longer wave was going "up" and to a shorter wave was "down". Hence Clinton B. Desoto's book title "200 Meters and Down" (yes, it should be metres) 160 is the longest wave hams can use, hence it's the top band. 73 de Jim, N2EY ** Gas prices getting you down?
