[Elecraft] [K3] Filter Cascade Effect
Thanks to Joe W4TV for recently mentioning the effect that cascading both the DSP and roofing filters can have when the nominal WIDTH setting is near the roofing filter BW. The following is part of a private message I recently sent which may be of interest to others: I chose my CW filters mainly based on bandwidth. I have 5-poles, which do have the offset issue, but I prefer their BWs. The published specs are: 500 - 565 (mine is 549) 400 - 435 250 - 370 200 - 224 (mine is 203) Another factor I didn't think about until recently is how the cascading effect of the DSP filter can significantly narrow the above. With my 500 and DSP set to 600, the cascaded BW is actually 426 Hz. My 200 with DSP set to 200 is actually 157 Hz. I feel the 500 combination is a little narrow for contest running and it may explain why I'm sometimes surprised to find stations calling me off-frequency that I didn't hear the first time (BTW this was sometimes true with Orion also). I really wish there were a filter around 700 Hz actual BW that would give me 600 cascaded. The 1k is just a little too wide for a heavy duty contest when folks are spaced 500 Hz or closer. Maybe the variable filters will be the answer if they don't have IMD issues due to using varactors. My point is to realize that the cascaded BWs may be 20-25% less than what you think the maximum BWs are from their specs. 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/-K3---Filter-Cascade-Effect-tp473531p473531.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Maybe the K3 software should adjust its DSP bandwidth so that you get a smooth variation of the cascaded bandwidth as you turn the knob. When the narrower filter engages, widen the DSP a bit. There's no way to make it perfect, but it has to be better than having the user fudge the filter bandwidths. 73, Carl WS7L ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] OT: ISP problems
Since this relates to the Elecraft reflector email, I guess it is just barely on-toic, so: I have had comcast for years and get almost all my mail directly through my comcast email address and read it with Eudora. Only problem I ever had was when comcast stopped passing along mail from a HPSDR reflector to me, thinking it was spam. This was just for a short time, and it was fixed. Back then, if your ISP also hosted another guy who was sending out spam, comcast might block legitimate email from you to me because of the spammer. I hope they have refined their anti-spam techniques now, but don't know for sure. People are coming to use their email as if had all the qualities of the US postal service, and for any ISP to stop delivering email arbitrarily can cause big problems.

I don't think this is a "good way" at all. Doing this destroys the smooth consistently incrementing operation of the WIDTH control. Your actual bandwidth goes from 600 to 550 to 400, then stays there until the DSP catches up at 400. If anything, I'd go the other direction so that the crystal filter doesn't engage until the DSP is inside it at a narrower bandwidth. However, another reason some people do what you suggest is to modify the passband shape since they prefer the rounder passband shape of the crystal filter ("softer sound", they say). I still think that is a negligible benefit against creating the WIDTH control anomaly. I agree with Bill that I'd much rather have my roofing filters just outside the DSP bandwidths I commonly use. That's why I think it is prudent for K3 owners to forgo additional crystal filters until they've operated the K3 and found the bandwidths most important to them. Then, if they really need nearby strong signal protection for the DSP, they can select wider crystal filters for their favorite DSP bandwidths. > Another point -- some have noted that at least some of the > roofing filters are actually wider than their nominal value. By design, INRAD makes the actual -6 dB bandwidth greater than the filter name.

[Elecraft] QRP Special Events Station K7S for Salmoncon
Margaret K7MWP and I are leaving shortly for Bowman Bay State Park, near Deception Pass, WA, for the annual Salmoncon event, sponsored by the Pacific Northwest QRP Group. Some people will stay in RV's. Margaret and I are packing our luxurious car-camping tent. A more modest backpacking tent is more usual for us. On-the-air activity for special events station K7S will be mostly on the usual QRP CW frequencies, and possibly some SSB as well, plus an occasional evening foray to 3588 kHz for some RTTY activity. That will be with an Elecraft K3 in its paddle mode: we will be sending Morse with iambic paddles and the K3 will spit out 45 baud Baudot RTTY and it will decode received Baudot on the monitor without need for an external computer. I'll also be operating my Elecraft KX1 on the 20, 40 and 80 m CW bands. There will be some 6 m and possibly 2 m activity as well. Elecraft guru Lyle Johnson KK7P and his wife Heather N7DZU will also be attending Salmoncon. Lyle will bring his K3 with the new subreceiver installed. I'm looking forward to giving that a whirl. I'll be giving a formal presentation to the group on "Geographical HF Exchanges," in which I'll be proposing that we totally abandon bogus RST exchanges for all Amateur Radio HF contesting and DXing in favor of 4-character Maidenhead Grid Field and Square coordinates, just like radio amateurs now do for VHF and above operations. At least when I'm operating, I'll be giving out the Maidenhead Grid. If you hear us on, please jump in. You might want to make a note of your Maidenhead Grid ahead of time. A nifty way to explore the Maidenhead Locator System is to check out the following Google Map facility for Maidenhead: http://f6fvy.free.fr/qthLocator/fullScreen.php . (In case the Elecraft list messes that up, it's http colon slash slash f6fvy dot free dot fr slash qthLocator slash fullScreen dot php .) Change the scale appropriately and then click and drag the map to bring your location into view and then click on the map to calculate your 6-character Maidenhead coordinates. The boundaries of that Maidenhead Subsquare appear on the map. Another approach is to enter 2- or 4- or 6-character coordinates in the Locate box and the map scale is changed automatically and the boundaries of that area appear on the map. Try entering BK19 to see the tiny sliver of the island of Hawaii which is within that 4-character Maidenhead Square. Try entering the 6-character Maidenhead Subsquare designator for Bowman Bay State Park: CN88qj. Wikipedia and the ARRL website have more general descriptions of the Maidenhead Locator System. The weather looks great in our neck of the woods. Our prayers are going out for our California colleagues who are being threatened by wildfires.

I don't want to elaborate but speak from personal experience! The real solution IMHO is about a 750 Hz XFIL which will net about 600 Hz when cascaded with the DSP. I had a 1k and got rid of it because it's simply too wide for serious contest use where it will typically span 200-1200 Hz at normal PITCH settings. For example, if you have 450 Hz PITCH set, that S9+30 guy 500 Hz up (at 950 Hz) will come roaring through your 1k XFIL and de-sense you. As I said before, maybe the variable filters will work...or maybe Inrad will do a 750 Hz filter. 73, Bill -- View this message in context: http://n2.nabble.com/-K3---Filter-Cascade-Effect-tp473531p473806.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2 audio pops
"Pops" when keying are not normal behavior for a K2. It is possible to cause some audio artifacts during keying because Elecraft allows you to do something many other manufacturers do not: you can set the T/R switching time arbitrarily short - right down to zero! The result of a zero switching time are artifacts of some sort in the audio, since audio is enabled while the T/R switching is actually taking place. That allows the operator full control over the QSK behavior you want from obviously too fast to absurdly too slow. I don't know if that's what you are hearing. It does not sound like it. Suggest a e-mail to [EMAIL PROTECTED] for some factory-level support. Terry reported a different sort of audio "pop" that is normal for a K2. It happens *only* when cycling the power. That is caused by electrolytic caps charging/discharging in the audio output stage. It does not have anything to do with keying, nor does it occur at any time except when turning power on or off.

RE: [Elecraft] K2 audio pops
-Original Message- The main reason I got the k2 is because of the excellent reputation as a CW rig. I can't understand why a cw rig such as this has to be operated in a special way to limit pops. I am sure the Ten-Tec guys are laughing at the fact that some k2 ops can't enjoy QSK - I've had several TenTec rigs. Their QSK is thumpy & clicky. My K2 (since sold) was very smooth and artifact free in comparison. That's the good news. The bad news is the switch over time was a bit longer in the K2 so listening between dits at 25 wpm didn't work so well on the K2. If you set the K2's T/R delay time to 0 you'll get more switching artifacts. If you run the rig's output through an audio filter that isn't well filtered, you may get RFI induced thumps in your audio. After using the K2, there is no way I'd go back to a TenTec. I love 'em but the K2's QSK is so much smoother to use, provided you (like me) don't have to have true QSK switch over times.

[Elecraft] OT: Software measuring S/N and signal strength thru soundcard?
In comparing antennas it would be nice to be able to run signals from the RX to a soundcard, and do analysis of signal strengths and S/N. Numerical data would give more info than comparing by ear. Actually, the K2 with its two antenna inputs is an ideal rig to this kind of experiments. Any suggestions for such software? 73 - Kristinn, TF3KX -- View this message in context: http://n2.nabble.com/OT%3A-Software-measuring-S-N-and-signal-strength-thru-soundcard--tp473971p473971.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] kpa100 swr bridge
Hello I just finished building the kpa100 for my k2 and need some help. All the test through building went as the manual said they should. But I have a problem with the swr bridge null adjustment. With the pka100 connected to a 2kw dummy load the k2 shows an swr of 9.9-1 on all bands. An inline swr meter shows an swr of zero. I went through all the adjustments for the bridge but the swr reading on the k2 didn't change. Can someone point me in the right direction. I can't find anything about this in the manual.

Re: [Elecraft] kpa100 swr bridge
Scott, Have you checked the cable between the KPA100 and your external SWR meter? You must obtain a good null for the KPA100 bridge before it can be expected to indicate anywhere near correct. If you have problems obtaining a null it is usually associated with a T4 problem - check T4 very carefully for well tinned leads - you should see a little of the tinned area above the board. Make certain the correct color leads are in the correct holes. Once T4 and the balance trimmer cap are correct, you will find that the forward and reverse trimpots (R26 and R27) will be close to the correct settings if they measure 43k ohms between the center lead and ground - set them initially to obtain that value. You MUST use an insulated tool to adjust the C1 trimmer - both ends are above ground and you will not find the correct balance point with a conducting screwdriver. Remove the external wattmeter (SWR meter) and attach the dummy load directly with a short coax when doing the balance adjustment - it can make a difference. Also note that an SWR reading of 9.9 is the highest value that the wattmeter will indicate, th eactual SWR may be much higher. Be certain the coax you are using is good. 73, Don W3FPR Scott McDowell wrote: Hello I just finished building the kpa100 for my k2 and need some help.

[Elecraft] K3: DSP filter steps; am I wrong?
HI all... I really wonder why there is so much discussion about the filter step size, which is currently 50hz. Maybe I am just nuts, but doesn't that 50 hz "come off" of each side of the BW? Here is what I imagine... I am on frequency A with a DSP filter BW of (say) 500 (lets ignore the roofing filter for now) and I hear a little QRM a bit above me. When I crank the DSP down to 450, isn't that moving the "leading edge" only 25 hz (and also the trailing edge). So in reality, am I not "changing" things in 25hz steps in terms of the offending QRM? Is there really a situation where you would need to narrow it 12hz instead of 25hz (and appreciate the difference)? Maybe those requesting a smaller step need it for PSK? But even then, it doesn't make a whole lot of sense to me. How often would adjusting the DSP bandwidth something less than 25hz (since that is what we have now), be better than just going to "full" 25hz? Or viewed from the other direction, if you want to narrow it even more, narrow it "one more step" and get really narrow. If I understand this correctly, great. But if I don't, please fill me in because I would genuinely like to find out more.

Re: [Elecraft] 1.8 or 2.1 kc Filter
As a contestor and DXer taht has used 1.8 and 2.1 filters - I prefer the 2.1 - I had a kenwood 1.8 and it was just 2 tinny sounding. I have used cascaded 2.1 Inrads in my TS-850s and it was good enough - I have a 6 khz the factory 2.7 khz and the 2.1 khz in my K3 - most the time I run my bandwidth at 2.8 which is just above thw 2.7 and it uses the 6 khz + dsp the audio sounds much nicer - but that it for uncrowded bands The 2.1 is tight and with the dsp it is just fine - when I crank down on the dsp bandwidth control I have to use the shift knob to get the audio to sound better.

Re: [Elecraft] K3: DSP filter steps; am I wrong?
Doug, I believe you are correct. I would also believe that most of the requests are coming from users who are attempting to use HI CUT and LO CUT at narrow bandwidths. What you say is correct if one uses the WIDTH control - the center filter frequency stays the same as the width is reduced, and if the desired signal is centered in the passband, the QRM will be reduced 25 Hz on each side. OTOH, the SHIFT also moves in 50 Hz increments, so there is some validity in asking for a reduction of the step size for the shift control - shift can easily force one off the edge of a narrow filter. But when the filter width gets less than 250 or 200 Hz, I can see little use of the SHIFT knob anyway, but that is my personal opinion, others may differ. So if one is using the HI CUT and LO CUT when operating at CW bandwidths, I suggest using WIDTH instead. Similarly on SSB, it is prudent to use only the HI CUT and LO CUT to maintain intelligibility while cutting out QRM. On SSB, the high end can be cut drastically, but the low end cannot be cut too much or intelligibility will suffer. With care, one could use a LO CUT up to about 350 Hz, but to my ears, 400 Hz or more of LO CUT will turn an acceptable SSB signal into garbage. 73, Don W3FPR DOUGLAS ZWIEBEL wrote: HI all...

Re: [Elecraft] VFO step size
Manuel, Yes, set the configuration menu (while in SSB mode) parameter for VFO CRS to 1.0 Values of 0.1, 1.0, 2.5 and 5 are available for SSB. VFO CRS is settable per mode. After setting VFO CRS to 1.0, pressing COURSE will toggle between 1.0 kHz steps and 50 Hz steps, but the RATE and FINE buttons interact too giving a range of steps from 1 Hz to 1 kHz. Once you make your selections, a bit of practice may be required to take advantage of all the capability available - but if you only want 1 kHz steps, all that is needed is to zero the low order digits and press course and you will traverse the band in even 1 kHz increments. 73, Don W3FPR Manuel Maseda wrote: Hello, Can someone tell me if the K3 can be configured for a 1K VFO step size in SSB mode?

The same effect can be observed with Inrad's filters. Looking at the 250 Hz pair for the TS-940, the 8.83 MHz filter is 367 Hz wide at -6dB but it is down about 2dB +/- 125 Hz from the center. when this is combined with a 455 KHz filter that is 265 Hz wide at -6db and 250 Hz wide at -4 dB, the effective bandwidth is slightly less than 250 Hz. 73, ...

Tune in a station exactly using a wide filter. 2. Adjust WIDTH = 1800 (or less). 3. Adjust either SHIFT (my preference) or HI/LO CUT for best audio. With proper adjustment you can get good intelligibility down to 1500 Hz. I believe my SHIFT setting is ~200 at ~1800 BW and goes up to ~400 at ~1500 BW, but let your own ears be your guide. I learned this back in my FT-1000MP days and it's absolutely necessary for using any rig at low bandwidths on SSB. I would only recommend a 1.8k for someone interested in contesting or perhaps DX-ing on the low bands. Unless you have extremely strong stations nearby, the standard 2.7k will still work fine and you can always narrow the DSP filter to <1800 when necessary. 73, Bill -- View this message in context: http://n2.nabble.com/1.8-or-2.1-kc-Filter-tp474117p474524.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] 1.8 or 2.1 kc Filter
I find that the 1.8khz filter is very useful for weak signal work on SSB. My QTH is noise free and i can routinely copy weak stations in the noise floor that cannot be heard on a wider bandwidth filters. I find the same with the K3 and the 2.1khz filter especially when narrowed down to 1.8khz DSP bandwidth. Weak signals just seem to pop out of the background. The only issue that i am having right now, which i am still trying to resolve with my K3 is that the IF shift appears to be off center frequency. I routinely have to shift the FC for maximum readability. I do have the filter FC offsets stored in the filter memories for now on my K3. I have the 1.8khz filter on order and will compare it to the 2.1khz filter shortly. I dont have any issues with copying SSB in the 1.8khz filter bandwidth, i find that even a 1.5khz filter like that on the K2 to be useful. I personally believe that you do compromise your SSB stations weak signal capabilities by not having narrow SSB filters. Wide filter bandwidths can becoming addictive and there is no doubt that it is pleasing to your ears.

However if you a Dx'er or contester thats > not what the games about. Well said, Craig. You don't use a 1.8 kHz filter because it sounds good! You use it because you can't pull the station through using a wider bandwidth due to close-in QRM and/or weak signal strength. You choose the bandwidth necessary to copy the station you're trying to work. If you're a casual operator or ragchewer, not really into contesting, DXing, or weak-signal work on VHF, the 1.8 and 2.3 kHz filters are probably not for you. As I write this, I'm in QSO with a station in northern New York on double-hop sporadic-E on 6 meters. He's getting weaker as the band changes, and there is a lot of adjacent QRM. I'm now running 1.5 kHz bandwidth with FC set to 1.00. Solid copy all the way, just signed with him and completed the QSO before the band took us out. Love this radio!

Re: [Elecraft] Maidenhead site...
The only way to know where you really are with perfect accuracy is to get a correct Lat/Long coordinate set and convert this to Maidenhead. GPS receivers can be set to read out directly in six-character Maidenhead, so if you have a GPS, use that to determine your correct grid locator directly. QRZ and other sites typically use the location of your zip code to compute your grid locator, as this data is readily available from the USPS. While this will almost always produce a correct grid square to four characters (not six), it often fails even four characters when a station is near the grid boundary.

Re: [Elecraft] 1.8 or 2.1 kc Filter
I find that using the shift control and sending things south a tad can help with this problem Even if you don't have a 1.8K filter try that with just a DSP filter width of 1.8 and use the shift and turn it downward until it sounds good. Then you can tune around the band like that and when they sound right you're pretty decently well centered up on the other station. ~Brett On Fri, 2008-07-11 at 19:17 -0500, Tom Childers, N5GE wrote: > On Fri, 11 Jul 2008 14:51:24 -0500, "Mike Miller" <[EMAIL PROTECTED]> wrote: > > >Anyone have experience with 1.8 and 2.1 kc filters for the K3? > >Trying to decide which one to get.. > > > >I am a DXer exclusively..not a contester... > >work CW rarely > > > > > >Does the audio from 1.8 sound too pinched? > >I just dont want to hear a 59+10 signal that is 3 kc..from the frequency I > >am listening on > > > >any thoughts? on what filters to get.. > > > >Mike Miller KA5SMA > [snip] > > I've had 1.8 filters in many different rigs over the years and found that I > rarely used them because, in my opinion, they are too narrow for SSB, making > it > sound tinny to me. > > Tom, N5GE - SWOT 3537 - Grid EM12jq > > "Those who would give up > Essential Liberty to > purchase a little Temporary > Safety deserve neither > Liberty nor Safety" > > An excerpt from a letter > written in 1755 from the > Assembly to the Governor > of Pennsylvania. > > Support the entire Constitution, not > just the parts you like. > > http://www.n5ge.com > http://www.eQSL.cc/Member.cfm?N5GE > > ___ > Elecraft mailing list > Post to: Elecraft@mailman.qth.net > You must be a subscriber to post to the list. > Subscriber Info (Addr.

Re: [Elecraft] 1.8 or 2.1 kc Filter
Personally I really liked the 1.8K filter in my rig during FD. The bands were packed and they'd allow you to squeeze into the tightest of places and take a run freq that you know the guy above and below you is being bugged by people calling you back but you can pick them out of the muck like magic. With judicious use of the shift knob you can center around the frequencies needed for intelligibility and you get all the frequencies that you need and ignore those that you don't. But you do need to be a lil ready to use RIT though.. ~Brett On Fri, 2008-07-11 at 15:30 -0700, Bill Maddock wrote: > As a contestor and DXer taht has used 1.8 and 2.1 filters - I prefer the 2.1 > - I had a kenwood 1.8 and it was just 2 tinny sounding.

[Elecraft] K3 - made bail!
It seems like the rear rubber feet for the K3 are the same as for the K2. I had two spares here and used double sided foam tape to attach them to the front bail ends. Now the K3 is at a much more appropriate viewing angle and looks much more like a tabletop HF rather than a large mobile. I highly recommend it, the bail height is just excessive if the radio is near viewing height (ie computer hutch) and the radio actually looks better with "legs".

Don't commit to any optional filters until you actually use your K3 and determine what bandwidths work best for your preferred operating scenarios. The stock 2.7 kHz filter provides excellent roofing filter protection for the DSP which is where you set your receive bandwidth. Try different SSB receive bandwidths and see what you like. I almost always use 1.6 kHz for SSB and do not find it at all "tinny" or "too narrow" in the K3 as some other replies are indicating. In most other radios, 1.6 kHz far too narrow, at least for me to copy easily. The K3, however, sounds beautiful at these narrow bandwidths. Don't make a K3 crystal filter decision based on experience with other radios, especially someone else's experience with other radios! The easiest way to narrow the bandwidth on SSB is to reduce HI CUT. Until you reach a bandwidth of about 1.5 kHz, you don't need to adjust LO CUT or anything else. This reduces bandwidth while moving Fc down with it. Effectively, adjusting only HI CUT simultaneously adjusts WIDTH and SHIFT ideally for SSB. This is far easier than adjusting WIDTH, then SHIFT to get the sound right. You can slide between 2.0 and 2.7 kHz to see how narrow you can go for the sound you want. So, assuming you have the stock 2.7 kHz crystal filter, and have told the K3 it is 2.7 kHz wide, start there and reduce HI CUT from 2.7 kHz to 2 kHz. LO CUT will remain at 200 Hz and you will end up at a bandwidth of 1.8 kHz. I think you will find that it sounds fine. I prefer these narrow bandwidths because they take out the highs between 2 and 3 kHz. I think this is more intelligible (in the K3) for communications. So-called "hi-fidelity" is something else. Once you get a feel for the narrow SSB receive bandwidth you like, then select a crystal filter that is outside that bandwidth, if you are worried about strong nearby signals interfering with the DSP's ability to provide the listening bandwidth you want. The Elecraft/INRAD 1.8 kHz crystal filter is actually about 1.9 kHz at the -6 dB points, so it won't affect your DSP bandwidths much at 1.7 kHz or below. If that's too narrow for you, then consider the 2.1 which will allow you to get to 2.0 kHz or lower since it is actually about 2.2 kHz. 73, Ed - W0YK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Personally, I think the 2.7 or 2.8 cranked down to 1.8 is good enough when you want to use a 1.8, but I wouldn't buy one.

Re: [Elecraft] K3 - made bail!
I should state that I greatly appreciate the current height of the bail it makes for a very comfortable operating position. *BUT* it should be noted that (IMHO) the display doesn't look all that good when its up on its bail w/ the default LCD viewing angle setting... The LCD viewing angle feature makes it so that things look very nice again. The only issue is that if you're standing over it then things get a little TOO dark. There are some good "happy medium" settings that make things look good pretty much everywhere.

Re: [Elecraft] Diode Selection for RF Probes
Jack It's really interesting to read the articles on your site. In QST recently there was an article about a crystal set and a self-biased fet was used instead of a diode and I think it was said that this gave a higher output. It would be interesting to see how that would rank in your tests and might prove useful in a probe.

The details are at http://www.cliftonlaboratories.com/diodes_for_rf_probes.htm Rankings are (no surprises here) germanium first, Schottky in the middle and silicon bringing up the rear.
