[Elecraft] Subject: Re: K3 Hum on Audio...
Phil, The mic element is not connected to the mic preamplifier until PTT is engaged (on most radios), so it still implies the mic is the pickup path. You said there is no hum with the mic removed from the front panel jack, right? Change mics; is hum still there? You also said you could suppress the hum by laying a hand on the KPA500. Capacity of your body is enough to bypass the hum energy. Could be time to check the resistance of your ground system. Two tests you can do to see if it returns: 1) Connect a 4-5 foot piece of wire to the mic pin that connects to the mic element and key the radio - hum? 2) Disconnect the ground wire. More hum or less hum? A high resistance ground can lead to RF getting into a mic and could just sound like hum, though AC pickup is more likely the source. Like you said it probably is lurking to strike again. GL, Ed *Note: my old workplace had such bad ground loops that it was nearly impossible to route audio or computer network wiring thru the comm room. I measured about 20vac on the ground system to my RF ground. Telephone circuits with twisted wire had so much 60 and 120 Hz hum it interfered with normal tracing tones. Unfortunately the company was unwilling to try fixing this. The building had 480, 277, and 120vac circuits and the 480 mains input transformer was 20-feet away. The building formerly was used as a welding shop. I resorted to using isolation transformers for my test bench ac supply to isolate from the ground system. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?

Re: [Elecraft] Real world use of 1.8 filter
I concur with Don and others (although I don't find tuning with the 1.8 kHz too hard), it really does help me to hear a DX, especially on lower bands where I have a S7+ noise floor (urban environment). I generally tune with the 2.8 kHz and then drop in the 1.8KHz in using the II filter setting. When setting the width to use the 1.8 kHz, it's best to use High/Low, rather than Width and reduce the high and increase the low until you drop down to the 1.8 kHz filter, this gives better audio and readability than just changing the width around the centre frequency - the final setting tending to be offset. BTW, if you are getting the 2nd receiver, getting the 2.8 kHz filter means you don't need to match a pair of 2.7 kHz filters, just get another 2.8 kHz for the KRX3. 73 de David, M0XDF (K3 #174, P3 #108) -- Whales have calves, Cats have kittens, Bears have cubs, Bats have bittens, Swans have cygnets, Seals have puppies, But guppies just have little guppies. - Ogden Nash (1902-1971) On 14 Jan 2012, at 04:29, Don Wilhelm wrote: Keith, Under what conditions do you use the 2.1 kHz filter and wish for the 1.8?

Re: [Elecraft] Real world use of 1.8 filter
On the other hand, the 1.8 KHz filter is my primary filter for SSB receive. I'm mostly a CW operator and when I get on SSB it is only for working DX or a contest. Fidelity is not an need. Once the high cut/lot cuts are set up for the 1.8, one can easily widen the the filter width with width control alone to allow better copy for XYL or broad signals stations. 73 de Brian/K3KO On 1/14/2012 04:29, Don Wilhelm wrote: Keith, Under what conditions do you use the 2.1 kHz filter and wish for the 1.8?

[Elecraft] [K3] suggested order for upgrades
Hello, I'll soon be able to add these parts to my K3/100+KAT3: 3 filters KBPF3 KXV3A KDVR3 KTCXO3-1 I'd like to minimize the dismount/remount needed to do this, but still I don't feel it would be a good idea to mount them all and hope it all works at the first time. Now, it should be possible to mount the KTCXO3-1 by just opening the top of the case. It should be possible to test it without having to close back the top, too. The KBPF3 shouldn't require access to the bottom part since the standoff are already there (iirc). Again, test should be possible without remounting the top. I could even do those two in sequence, and just test them together. I'd then go on with the filters (which require access to the front part of the bottom), and then proceed with either the KXV3A or the KDVR3, which both require extensive dismount/remount. Any better ideas?

[Elecraft] K3: Real world use of 1.8 filter
My 2 cents: For rag chewing the stock wide filter is fine. In fact, I still use the stock SSB filter in both of my K3s and I am a pretty serious contester (nobody holds more current CQWW USA contest records than I do). Remember that a roofing filter is NOT what determines your final IF bandwidth. It does, apparently, contribute a little, but the DSP filtering is mostly what is doing that. So for me, the difference between how many signals are going to fall inside your passband when from 2.7 to 2.1 to 1.8 on SSB is, well, not much. If anyone in the USA has such a concern, for me, is appropriate only for contesting. Even when DXing, either your calling on his frequency or if split, well, hopefully he is asked for a split of more than just up 1. Remember, this is SSB. Some will say that on 80/160, there are a very few number of DXing occasions where the narrower SSB filter can help. I won't argue that. I have to wonder out loud how many guys are feeling the DSP filter width impact when they go from their 2.7 to 2.1 to 1.8 on SSB versus how much of that is improvement in IMD reduction specs. For 99%, they probably are feeling the narrower DSP filter impact (which means the narrower roofing filter has essentially no impact at all). If the SSB band is packed with wall-to-wall very, very, very strong signals, then I'm betting that the roofing filter BW just won't matter for the vast majority of ops. Are there times when the narrower roofing filters are better? Probably a handful per contest. But for me, when contesting, I really don't want to deal with such a situation. I can probably have a better rate (if I'm running) by finding a better QRG to attempt to run (call CQ). It's mostly how much you want to defend your frequency versus how much you want to improve your QSO rate. YMMV. So to summarize...for my 2 cents, for rag-chewing the stock SSB filter is VFB. de Doug KR2Q __ 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

Re: [Elecraft] K3: Real world use of 1.8 filter (oops)
I will roll with the current setup for awhile but i have seen on several occasions how I can deploy the use of the 2.1 kHz filter in noisier band conditions say on 40m to improve intelligibility and readability of weaker signals. If the 1.8 kHz filter will continue in that line of improvement, it would probably be warranted down the road to add the 1.8 khz filter and reconfigure my current setup on this K3.

Re: [Elecraft] K3: Real world use of 1.8 filter (oops)
Not sure what you mean by feeling. As the filter BW is narrowed, I usually shift the Fc down as well. This gives more balance to the heard spectrum, which is a change of course. When the roofing filter shifts from 2.8 to 1.8, I can't feel a transition, maybe because of this operating method. The only way I've really ever perceived a transition is when using the XFIL key to change roofing filter. The transition is abrupt, as expected. I notice a reduction in distortion using the 1.8 filter in crowded conditions. Seems like most folks would notice better intelligibility, but can't really sense distortion as such. Contesters excluded, of course. They can and do notice. I feel a lot more IMD reduction in CW, while changing the DSP filter bandwidth. Much more. Filters here: 0.25, 1.8, 2.8, 6.0, 13.0. 73, matt W6NIA On Sat, 14 Jan 2012 09:28:00 -0500, you wrote: I would like to change one word in the following paragraph.

[Elecraft] K3: use of 1.8 filter - clarification
I've received emails replies (direct and otherwise) that, for me, indicate that I should elaborate/clarify what I am referring to. Let's assume that you have a 2.7 and 2.1 roofing filter. If you set up your narrower SSB filter according the the manual, which is what the majority of K3 ops do, as you transition from, 2.7 to 2.1 using the width knob, you are doing two separate, but linked things. First, you are reducing the DSP BW. Sync'ed to that (you have no choice without manual intervention, ie faking out the K3), as you get to 2.1 kHz in the DSP BW, you simultaneously switch from the 2.7 to the 2.1 roofing filter. Unless you unhook this coupling between the DSP BW and the Roofing Filter BW, you simply cannot tell which one is influencing what you hear (what I called feel). So when you get down to 2.1 (from 2.7) are you appreciating the impact of the DSP or the roofing filter - or maybe both? How would you know? I am saying that unless you are operating in extremely crowded band conditions (not with just one interfering, very near-by station) you are appreciating the impact due to the DSP BW and certainly NOT the roofing filter. It is possible to manually intervene to alter (even temporarily turn off) the (point of) sync between the DSP BW and the roofing filter (narrower) BW. And I am saying that unless you actually do this de-linking, that you won't be able to know/confirm the true source of what you are hearing / feeling. I'm betting that for the vast majority, especially non-contesters and non-160 serious DXers, what you hear is due to the DSP BW. The roofing filters are used for reducing IMD. A receiver with poor IMD will experience phantom signals due to the mixing of other very strong signals (multiple) on the band and these phantom signals can potentially cover up real, but weak, signals. You can usually identify such IMD as received squeaks, pops, whines, groans, etc. The band will sound like it is covered with garbage - even somewhat musical. The addition of the appropriate roofing filter can reduce or eliminate this. This is esp true (for me) on CW and especially (for me) on the low bands (lots of very strong signals) during a contest. In the old days, I've had many receivers that would simply collapse under the strain. It made tuning across the band painful and arduous when trying to pick out weaker signals. After hours and hours of this, it is very fatiguing. I use the 5 pole 500hz filter on CW for both of my K3s. Is it wrong to get a narrow filter? Of course not. But unless you are planning on operating in the midst of multiple, super strong signals, then I do not see much logic in getting a narrower CW filter...and certainly not a narrower SSB filter for SSB use. At least on CW, you can fit another signal inside the passband (very rare) when going from 500 to 200hz, but on SSB, going from 2.7 to 2.1? No way that will fit another signal in that delta (which is half of the difference or just 300hz.). Now, if you have the sub-receiver and want to match filters, then I see nothing wrong with buying one of the narrower (or even wider) SSB filters. But that would be motivated by a different reason. If you're spending money frugally or even just being thrifty, (however you want to define that) you can stick with the 2.7 stock filter. If money isn't an issue (the cost isn't that much different), you sure can't be hurt by getting a narrower SSB filter, except as cited by others, when it comes to ease of tuning in a station (though I have never experienced such difficulty). Lots of folks simply like to load up the open the slots. That is yet another motivation...not much to do with operating. Hope this helped to clarify what I was trying to get across. de Doug __ 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

Re: [Elecraft] K3 Hum on Audio...

Jim, Well, I would call it mostly a buzz. Also, the only near magnetic field of the KPA500 power transformer is off, I mean powered off and unplugged, so that does not seem to be the problem. I just ran another test with everything disconnected, including ground and coax. With the K3 in TEST mode, key-down on the mic still produces the hum. I double checked the grounds. I did this because if I were to touch anything metal on the k3, the metal part of the PL259 or the ground strap, the hum is damped quite a bit to almost insignificant. It seems that if my rig were already well grounded this would not happen so I am curious if this is something I would normally expect. I will experiment with the TXEQ but this is a real puzzle I would like to solve, not merely erase it. 73, phil On Jan 13, 2012, at 9:37 AM, Jim Brown wrote: On 1/13/2012 9:20 AM, Phil Hystad wrote: Unfortunately, it is in both mics but not as strong in the Yamaha CM500 mic as in the MH2 but it is present. Clarification question. Is it HUM (pure 60 Hz), or BUZZ (mostly harmonics of 60 Hz)? If it's HUM, I would suspect magnetic field coupling into the audio, either from a big power transformer (like the one in a power amp or a big linear power supply) or from a AC power wiring fault called a double-bonded neutral. The K3 has unshielded audio transformers at all the audio inputs and outputs, and an unshielded transformer is a sitting duck for magnetic fields. The good news is that the K3 has excellent audio equalization (TXEQ) that allows us to remove that 60 Hz hum by filtering. The lower audio frequencies in the human voice make NO useful contribution to speech intelligibility, but they do waste transmit power. So it is ALWAYS a good thing to set the TXEQ for maximum cut of the lowest two bands, and at least some cut of the third band. This is true with virtually ALL mics and ALL voices. AND it will reduce that hum enough that you may no longer hear it. There are several solutions to magnetic field coupling. 1) Rotate the noise source or the victim circuit to put the fields at right angles to the victim. 2) Move the noise source further from the victim. 3) If the hum field is produced by that AC power wiring error, fix the error to eliminate the field. 73, Jim K9YC __ 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 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 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
Re: [Elecraft] K3: use of 1.8 filter - clarification
Hi Doug, DOUGLAS ZWIEBEL wrote The roofing filters are used for reducing IMD. I agree IMD reduction is not a big issue on SSB but blocking dynamic range (BDR) is the primary reason I sometimes need a narrower filter. If you have an S9+25 SSB signal CQing next to you (sometimes the case in crowded contests), a narrower filter will prevent it from de-sensing your receiver. If part of the interfering signal falls inside your 2.7k filter, signals on your frequency will be gain modulated by his signal (commonly called AGC pumping). In this case a narrower filter will prevent the problem. Of course when this happens, we still have to contend with his transmitted splatter (typical SSB TXs run -35 dB IMD which would result in ~S7 splatter from an S9+25 signal), but at least you can still copy signals at S7 or above (and lower when he's not transmitting). 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-use-of-1-8-filter-clarification-tp7187876p7187921.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] First QSO using the KX3's built-in RTTY mode
The KX3 will have the same built-in RTTY and PSK31 modes as the K3: just set the DATA mode for FSK-D or PSK-D, and turn text decode on. You can then send CW with either the attached paddle or an external paddle and the KX3 will convert it to RTTY or PSK31. The VFO B display is alphanumeric, and it can display on-air data signals. No computer needed. I just made the first QSO using the KX3's RTTY mode (FSK-D), running 12 watts. Lots of activity in the 20-meter RTTY zone today (14080-4090).

Re: [Elecraft] K3: use of 1.8 filter - clarification
That really IS the kicker. I guess the point is how bad do you want/need the cost of an extra filter. How important would it be in the 1% condition where the signal up or down is INSIDE the roofing filter. In my experience from home (not the monster antennas out at N4AF), in ANY phone contest, changing the width from 1.8 to 1.9, thus changing to the 2.7 roofer, always is a large jump in crap inside the DSP. This is because I just went from DSP and roofer ALIGNED SKIRTS, that drop 100+ dB in a given width (combined) to a composite skirt that only drops 50 in the same range. This means that the loudness of what is just up and down JUST GOT 50 DB LOUDER at the roofer change, because the close in skirt is now ONLY DSP instead of DSP+roofer. The DSP is great, but hear this, at 400 Hz, the straight selectivity of DSP plus a CAREFULLY ALIGNED 8 pole roofer is still less than my MP with INRAD 400 Hz 8 pole filters at the 8 and 455 IF slots. The presumption with no tight filters is that the selectivity of the DSP by itself is enough. Personally, my experience is that the K3 DSP, by itself, as very excellent as it truly is, is NOWHERE near enough to deal with contests and situations where one is trying to listen to a 0.05 uV signal next to a 500 or 5000 millivolt signal that is JUST BARELY OUTSIDE the passband. It takes the DSP, as excellent as it is, TOO MANY Hz to reach the ultimate 100 dB. I need the FASTER DIVING COMBINED skirts of a matched roofer and DSP skirt to knock off the content just barely up and down. While my MP has faster diving skirts at 400 Hz using the matched INRADs, the K3 nearly matches the skirts AND has vastly superior IMD and internal noise. ***BUT*** without the matched DSP and roofer skirts, particularly if the roofer is significantly wider, there will be so much stuff let in by the missing 50 dB of skirt inside ultimate rejection that the advantages of the superior IMD are quashed by all the stuff now let in, and in fact, in that particular situation, the MP would be the superior rig. Credit where credit is due. When I am running at NY4A on 40 with the overwhelming signals from Europe on the monster quad, I use the 400 roofer and DSP at 450 and the 250 roofer and DSP at 350 to get sharp aligned hard-diving skirts just above and below. Don't bother to tell me that some of those Italian signals are running anywhere near 1.5 kW because I've rechecked the S meter countless times, and something that tickles 40 over is an issue. You COULD say, just reduce the width, and I would agree **IF** it weren't for so very many people calling fairly well off frequency. There are times where I have to reduce the width from 350 to 300 or 250, where the up or down signal is just too strong and too close and overwhelms the excellent roofer/DSP combo at 350. But I know I'm losing contacts. I know this is more like a NASCAR take on tires, and some of you may be driving the K3 like the family car. But if you understand the NASCAR (severe contest) issues regarding roofer selection, then you know what it's about and can choose one way or another and know it's right for you without being snookered. If you occasionally take the K3 down to the race track and want it to perform out there, you need to match DSP and roofer skirts, and align them. 73, Guy.

[Elecraft] K3: Real world use of 1.8 filter (oops)
This topic has been pretty thoroughly discussed, so excuse my additional comments. In summary, I think the majority feel either the 2.7 or 2.8 KHz filter adequate for general use, since one has the ability to narrow bw using DSP. I have only the 2.8 (in both Rx) and 400-Hz filter (in the main Rx). I do mainly weak-signal work where narrow bw is important to reduce white noise. On CW-eme it is common to run at 100Hz for this purpose as it increases SNR. The DSP filter handles that really well since the objective is to eliminate noise at the detector (which the DSP filter does). A narrow roofing filter has significant use keeping strong off-freq RF from causing IMD, or affecting the RF gain stages. This is typically found in high-density HF contests (which I do not participate in). I chose the 8-pole filters thinking the steeper skirts might offer a slight advantage in crowded band conditions. For HF CW the 400-Hz filter makes copy really arm-chair nice as it almost results in hearing only the one intended station in the passband. On CW-eme I haven't decided if 400-Hz roofing filter offers any advantage over the DSP filter. I suspect not. That all being said, I did order the roofing filter for my new KX3. Why? Because I expect to travel with it to areas where that will be more important. Hill-toping with it portable can expose one to nearby strong signals (even IF feed-thru when running with VHF-mw transverters). Being a direct-conversion SDR, RF filtering is more important to keep out unwanted RF energy. So roofing filters generally will not hurt performance if used and may help in some situations. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?

Re: [Elecraft] P3 SVGA Adapter with FFT Processor now available to order
The decision goes back to the earliest stage of design of the interface. It is my personal opinion that Elecraft made the wrong choice at the bifurcation of paths in the design process. An interface of the type mentioned by K2AV would have greatly increased utility -- broader applicability -- than the simpler one that requires a dedicated monitor. As far as I am aware, there was never a vote (as you put it) taken on this point...it was summarily decided by Elecraft that the P3 would require a dedicated monitor. I am not suggesting that design be generally done by vote, just that in this case, windowing the output makes much more sense. As far as being a little option goes, perhaps you should examine the posted price -- it is scarcely a little option -- it is about 35% of the price of the P3 itself, and when an el cheapo monitor is added on, it begins to be more like 50% of the cost of the P3.

John, The P3 does not requires a dedicated monitor. The SVGA adapter offers the opportunity to use a larger, higher resolution, dedicated monitor as an alternative to the built-in display. You are becoming rather one-note about your desire for a windowed display on your computer. If you want a windowed display, get an SDR-IQ with SpectraVue or get LP-Pan with son of PowerSDR.

[Elecraft] K3: use of 1.8 filter - clarification
IMHO, there are few folks in the contest world that are better technically than Bill (W4ZV), so I would suggest that everyone take his comments very seriously. Bill...I do have a question or two, with respect to your statement below. 1. Just how often do you find that you run into a situation such as you describe below? I don't mean simply, during every a contest, I mean more like how often during a contest? For how many Q's? 2. If the really close and really strong signal is pumping your AGC, why not just turn off the AGC and ride the RF? This is not a rhetorical question, because I know you do this. So I'd like to learn why you would, in some situations, prefer to not do that. I would love to learn a new trick! 3. And just out of curiosity (on SSB), how long would you tolerate being so close to someone who would pump your AGC? Of course, for me (QRP), the answer is zero seconds. :-) W4ZV said: I agree IMD reduction is not a big issue on SSB but blocking dynamic range (BDR) is the primary reason I sometimes need a narrower filter. If you have an S9+25 SSB signal CQing next to you (sometimes the case in crowded contests), a narrower filter will prevent it from de-sensing your receiver. If part of the interfering signal falls inside your 2.7k filter, signals on your frequency will be gain modulated by his signal (commonly called AGC pumping). In this case a narrower filter will prevent the problem. Of course when this happens, we still have to contend with his transmitted splatter (typical SSB TXs run -35 dB IMD which would result in ~S7 splatter from an S9+25 signal), but at least you can still copy signals at S7 or above (and lower when he's not transmitting). 73, Bill __ 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

Good Evening, I am happy tonight sitting by my warm fire reading as the snow level mounts. Winter finally arrived and decided to drop about two feet of snow on me. Luckily there was some warning so I am ready for a few days without access to the outside world and possibly a power outage. Five days of firewood are stacked inside and I have plenty of water ready too. The battery bank is charged so there is no problem with comms. There is enough power in those Trojan T-105s to last well beyond even longer periods without electricity. Propagation has been great this last week. Some flutter but signals are good. I have been busy reading spec sheets so have not spent much time with my rigs. My electronics bench got cleaned all the way down to its surface and the instruments were restacked to allow more space there as well. It is amazing how easy it is to find things when your desk is clear :) Even SMT is not so bad because I have large sheets of sketching paper taped onto the desk to protect it from soldering. Great for taking notes and finding that errant SMT capacitor.

Hi Bill, My K3 #4257 had the 13KHz 8 pole, the 6KHz 8 pole, the 2.8KHz 8 Pole filter + the 2.1KHz 8 pole originally, the 400Hz 8 pole CW filter. I swapped my 400Hz CW filter for the 1.8KHz 8 pole SSB filter I have now with a fellow Elecraft owner here on the list. Once I got it, I found that I was using the 1.8KHz filter more than the 2.1 for both contesting and rag chewing to the point where now I have removed the 2.1KHz filter due to non use.
