Re: [Elecraft] [Elecraft_K3] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes
I just downloaded the newest K3 beta release, and don't seem to have anything like the issue you describe. It seems to work very well! Not sure what to tell you, but unless others indicate a similar problem it may be rig specific. I do notice something else that is odd, and wonder if anyone else has seen this happen. Several times now, since adding the APF feature, when I first power up the P3 I get a screen full of nice big spikes, most of which are false! I center on some nice spikes on the spectrum display, but there's nothing there. However, if I just recycle the power to the P3, the issue seems to go away, and only valid signals are displayed. By the way, I had previously posted that I was having problems with my reference level setting. Initially I was getting a noise floor at -130 dbm or even lower. Turns out I had a bad choke in the K3 (RFC22). Mine is an older K3, and I did have to make the mod to replace R8 with the supplied 13K SMT resistor. Anyway, that RFC appeared to be open, as I was getting no voltage on the low end. I have a replacement SMT part coming, but in the meantime I scrounged up one from my junkbox that is nearly the correct value, and voila! Everything seems to be as it should now. I'm just curious if I somehow torched the original RFC, when I replaced R8, or whether it has been bad all along, and it was only the addition of the P3 that made it obvious. Guess I'll never know!

[Elecraft] Firmware 4.18 APF adjustment using shift control
Gentlemen, thanks for adding the APF to the K3 and the quick response to the bug that some operators were experiencing. The APF works great. I did find that while adjusting it when I got to APF 1.0 I heard a click in my headphones that I am using and as I tried rotating the shift control counter clockwise or clockwise that I could here the APF stepping but there was no visible indication on the display of it or any receiver audio heard. Just the clicks as I turned the shift control. Turning off the rig and turning it back on brought everything back to normal. 73, Len K3LJ -- View this message in context: http://elecraft.365791.n2.nabble.com/Firmware-4-18-APF-adjustment-using-shift-control-tp5711904p5711904.html Sent from the [K3] 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

Re: [Elecraft] Firmware 4.18 APF adjustment using shift control
K3 #202, MCU 4.18, et al. Similar experience here. Everything normal until I rotate the APF Shift CW and it reaches 1.00 the loud pops/cracks begin when rotating both the Shift and Width knobs. Rotation of the APF Shift knob now changes the display numbers (APF 0.xx), but the Rx is very quiet... both speakers and earphones. Powering K3 OFF/ON returns the K3 to normal operations. When I cycle back to APF Off (Preset II on my K3), Rx works normally with sound in both speakers and earphones. The first time I switched back to Preset I (APF On) the Rx worked as it should. Subsequently, switching back to Preset I produces a quiet Rx with only the popping when the APF Shift or Width being rotated. 73, Ken K3IU On 11/6/2010 7:46 AM, Len, K3LJ wrote: Gentlemen, thanks for adding the APF to the K3 and the quick response to the bug that some operators were experiencing.

I just replicated your issue on my K3! Once I tuned the APF above 1 kHz the crackling begins. During this time the APF function disappears and with each step on the display a loud CRACK! is heard in the speaker. Once I tune the APF below 270 Hz the CRACK! goes away and the APF is restored. At 1 kHz I hear a loud POP! and then the CRACK! occurs for each step as the knob is advanced to the right although the displayed APF frequency remains at 1 kHz. At 270 Hz I hear a BOOP! and APF is restored. I've done this several times as I've typed this message. When the APF is in the crackle mode, turning it off and then on does not change the crackle state, in fact more crackle is heard upon reactivation. Powering off the K3 while in crackle mode kills the crackle and APF resumes its function. I am running MCU 4.18, DSP 2.67, and FPF 1.14 on K3 #4762.

More tests... My previous report was with the sidetone set to 600 Hz. I set my sidetone pitch to 670 and the point at which the APF returns to normal moved up to .27 (270 hz). I now hear the same boop as Nate reports and a return to normal . 73, Ken K3IU ~ On 11/6/2010 9:36 AM, Ken K3IU wrote: After someone else noted that turning the APD Shift CCW it returned to normal ops when reaching 0.27.

Hi Lyle, SSB output is certainly improved in F/W 4.18 compared with 4.17 but contrary to what some others are saying it seems to me still to be down compared with 4.14. This morning I did a tx gain calibration and noted output from the amp under 4.14. I then installed 4.18, cycled power on and off and did another tx gain calibration.

I just loaded this beta version 4.18 and now I get loud crackling from the speaker when tuning though the APF filter, also, the audio goes away. This seems to be an out of range issue with the encoder. The APF would normally tune 200 - 1000 Hz and the crackling seems to correlate to turning the encoder past the upper limit. Normal operation can be restored by turning the encoder below 200 Hz to clear the wrap. 73, ...

This release includes our new APF (audio peaking filter) for CW mode, which has been helping K3 field testers work extreme weak DX for the past several days. For voice modes, there's a Fast Monitor option (TX voice monitor without the processing delay). Also included is a much-improved TX Noise Gate. This release fixes a problem with low initial output in SSB Tx. See detailed release notes below. Please send any questions tok3supp...@elecraft.com.

Otherwise your menu text will be incorrect. * APF (AUDIO PEAKING FILTER) ADDED: APF provides enhanced copy of weak signals in CW mode, and is especially useful when signals are at the noise level. The K3’s APF is patterned after the most successful analog APF implementations, and is equally effective in user tests. To use APF, make sure CONFIG:DUAL PB is set to APF. (This is the default. “NOR” restores the original DUAL PB function.) Then hold DUAL PB to turn APF on/off. A special DSP graphic display is used to show that APF is in effect. At the time APF is activated, the regular I.F. SHIFT setting, if any, is “frozen,” and SHIFT then controls the center pitch of the APF filter in 10-Hz steps. APF is independent for the main and sub receivers, as well as for presets I and II. Switching between these two presets is a convenient way of turning APF on/off quickly. * ADDED VOICE TX “FAST MONITOR”: Normally the voice monitor includes a ~20-ms delay, which is necessary to hear how your on-air signal will sound (with compression, etc.). If you prefer to not hear any delay in the voice monitor, set CONFIG:TX MON to FAST. Note: You’ll still hear the delayed and processed monitor if you adjust the MIC, CMP, TX EQ or TX GATE settings while transmitting. * TX NOISE GATE IMPROVEMENT: The Noise Gate/Downward Expander for voice modes has smoother response and much improved performance near the threshold. * NARROW AF FILTER IMPROVEMENT: Adjusting SHIFT when using very narrow DSP filters no longer causes ‘pop’ artifacts.

[Elecraft] K3 - 160M Country #219 TNX to APF
Boy, I'm sure glad that I downloaded the Beta version of the K3 firmware with the new APF feature. I noticed a 160 Meter putout for KH2/N2NL this morning just before our 11:44Z sunrise at this VA QTH. I tuned down to 1817.5 KHz only to hear noise...then a pee weak, unreadable signal. I switched on the new APF feature and up popped the signal from Guam, now 449. We exchanged reports and 73 and K1HTV Topband country #219 was in the log. That's 219 countries on 160 Meters with 100 Watts or less. FYI, the antenna on this end was an Inverted-L, 70 ft of it vertical, used for both TX and RX. Heard nil on the Beverages. K3What a radio!

Re: [Elecraft] APF vs ordinary filters?
The passband shape is that of an inverted V with a sharp tip. While this can be remarkably useless for tuning around, the regular passband shapes being better for that, once a real weakie is discovered, tuning the APF to it creates an immediate signal to noise improvement. It is so narrow though that one can tune past a weak signal and not hear it.

[Elecraft] New K3 - No TX Audio
One of the three new K3's we purchased for use at our state RACES station has no TX audio. All three were unpacked today, and, the first one to see the light of day (and, an antenna) doesn't know it has a mic attached to it. The PTT works, there's just no audio at all into the rig. Nothing is heard via the monitor, no ALC action, nada. The transmitter is working as it generates 100W of CW. The ops are reporting that they simply have no TX audio. The other two K3's worked normally when hosed up to the same mic. I've had the ops walk thru the quick set-up chart, checking the CMP/ALC and mic gain settings a couple of times with the same result each time.

I cannot say which jumper it is, but I recall there is one - look in the Microham documentation.

Have you connected the Line In and Line Out connectors from the microHAM DB37-EL-K23 or DB37-EL-K3R to the correct jacks on the K3?

Re: [Elecraft] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes
Hi Lyle, Did something else change with the way mic gain and bias is handled? Prior to 4.17/4.18 with mic bias set to LOW, I couldn't turn gain up past 5 before ALC started to reduce drive. At a setting of 4 or 5, I'd get 5-7 bars ALC at voice peaks. I always chalked this up to the fact that the MH2 had a hot element. Last night, I got on 10 meters to talk to a friend on a repeater, and noticed that I had to crank gain up to 10 to get the same level of ALC action. Bias is still set to low. I checked on other bands, and a mic gain of 10 now seems to be the sweet spot. Reducing mic gain back to 4, and I'd barely get 1 bar of ALC to flicker. I don't mind this at all, but am curious if other things were impacted and require adjustment i.e., TX EQ settings, compression, etc. Thanks, James K2QI On Fri, Nov 5, 2010 at 8:48 PM, Lyle Johnson k...@wavecable.com wrote: On 11/5/10 5:44 PM, James Sarte wrote: Hi Lyle, Nice work.

Unfortunately Lyle is out of town, so we won't be able to make corrections this weekend. If you have any issues with rev 4.18 (or 4.17), please re-load the last production release, rev 4.14. NOTE: You must download a complete set of files (MCU, DSP and FPF) when upgrading or downgrading. 73, Wayne N6KR __ 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] SolderingStation Selection
I am waiting for my K2/100 to be delivered. In the meantime I am deciding on what soldering station to buy. On the Elecraft web site there is a posting to stay away from soldering irons 40 watts and 850 degrees. I am looking at a Weller 50 watt and variable temp from 350 to 850 degrees. It is a model WES51. Is it ok to use this soldering station on the K2/100?

Re: [Elecraft] SolderingStation Selection
I bought an Aoyue 937+ digital controlled ESD soldering station. It's Chinese made and nowhere near as expensive as American brands, but works well and holds temperature just fine.

Re: [Elecraft] SolderingStation Selection
Paul, Sorry to hear about your confusion. First, a soldering iron is different from a soldering station in that the former is not temperature controlled - although the word usage sometimes becomes garbled and some will refer to them interchangeably. The 40 watt limit is there for those brave souls who want to use a soldering iron to assemble their K2s. For soldering stations, the temperature range is the important factor. The extra wattage will allow a smaller tip to be used. So, yes, that is a good soldering station to use for the K2. If you are not quite familiar with soldering on boards with thru-plated holes, please review the soldering tutorial so you can see the appearance of good and bad solder connections. It is available for download from the Elecraft website and a printed copy will be included with your K2 kit. Remember that most builder problems come from unsoldered or poorly soldered connections and also from poorly tinned toroid leads. While Elecraft does not discourage the use of lead-free solder, I do not recommend it unless absolutely required - it has a higher melting temperature and does not flow out onto the solder pad nor the component lead well. My recommendation is for a eutectic solder alloy (63/37) with a mildly reactive flux - like Kester 285. While Kester 44 is also suitable, it has a highly reactive flux which will clean better, but will leave more solder residue and is not necessary for new boards and components. Save the Kester 44 for antennas and old components that have developed oxidation on the leads. A note on the eutectic alloy - that is the alloy with the lowest melting point, plus it has no plastic state - it goes directly from a liquid to a solid. The old bug-a-boo of cold solder joints (crystallized) caused by movement as the solder is cooling will disappear with a eutectic alloy. For lead/tin solder, that magic alloy is 63/37. 73, Don W3FPR On 11/6/2010 6:33 PM, pagog...@stny.rr.com wrote: I am waiting for my K2/100 to be delivered.

Re: [Elecraft] Firmware 4.18 APF adjustment using shift control
Please don't be so quick to judge the Alpha testers! We did plenty of testing on this software before it was released for Beta test by the public.

Re: [Elecraft] SolderingStation Selection
That looks like a good choice, Paul. The temperature range, heat capacity and tip sizes important characteristics IMO. Knob temperature control like the WES51 is extremely useful. Most soldering is done at 750F and if I use some solder wick to remove solder I bump it up to 800F to compensate for the heat-sink effect of the wick. I use a 1.6mm wide chisel tip for 99% of my pc-board work. The narrow edge provides a very small point for small pads while the wide side works on most pads - even fairly large pads such as used to mount BNC connectors on the board. For very tight, small spaces a conical tip is good to have. I have a HAKKO 936 so I am not personally familiar with the Weller, but good heat capacity is important to avoid temperature droop or cooling of the tip by cleaning or just soldering a large-than-normal pad. The biggest danger to your pc boards is cooking a trace with the iron for too long. That will debond it from the board underneath and is caused more often by prolonged heat at lower temperatures than by higher heat for short periods. I set my temperature and choose the tip so that solder melts within 2 to 3 seconds after the iron is applied. Ron AC7AC -Original Message- I am waiting for my K2/100 to be delivered.

Re: [Elecraft] Firmware 4.18 APF adjustment using shift control
Guy, Firmware 4.18 is still available at the Elecraft website - it was 4.17 that has been pulled AFAIR. Yes, 4.18 has some problems that have been identified on this reflector, but for those who are willing to work around those problems, I am certain the firmware folks at Elecraft would like to have feedback of any other problems discovered. Those who wish to play it safe should definitely retreat to 4.14 (install all the files), but for those who are a bit more adventuresome, try out the APF and the improved noise gate, etc. as long as you are willing to work around the limitations that have been identified so far. I often use beta releases of software, and I do expect a few glitches when I do - I figure that is my cost for trying something new.

Re: [Elecraft] SolderingStation Selection
I'm far from an expert on this topic, but I bought myself a WES51 a few years ago, having previously only used soldering irons... it was quite an enlightening experience - I'll never go back! It seems that the Weller accessories (wide variety of different tips, replacement sponges, etc) are very readily available (Fry's electronics around here), but I see the Hakko stuff around a lot too. I'm sure either would be fine for building a K2. ~Iain / N6ML On Sat, Nov 6, 2010 at 11:19 PM, Ron D'Eau Claire r...@cobi.biz wrote: That looks like a good choice, Paul.

[Elecraft] K3 mic gain and bias settings
Greetings Elecrafters, I previously posted a question to the group about mic gain settings in conjunction with the Elecraft MH2 hand mic. Prior to the slew of recent firmware updates, I had to set microphone bias to low, and keep the mic gain at 4 or 5. Anything higher, and ALC would start to reduce power. At those settings, speaking normally would give me 5-7 bars of ALC as recommended in the manual. Several folks have written to me stating that their K3 also behaved similarly and thus required the same amount of mic gain as I've written. Today however, after testing firmware versions 4.17, 4.18, and then reverting to 4.14 I've noticed that mic gain now needs to be set to 15 in order to achieve the same results. I'm curious if anyone else has noticed this. There doesn't appear to be anything out of the ordinary in terms of performance, but was curious as to why the sudden difference what else could have been affected.

Re: [Elecraft] SolderingStation Selection
Hi Paul, I have both the Weller WES51 and Hakko 936 (rhymes with Taco) on my bench. Both are excellent soldering stations. I've had the Weller for many years and bought the Hakko as a backup a few years ago. I usually flip the switch on the Hakko when I have a soldering job to do. The Hakko is hard to beat for the money, heats up fast, recovers quickly. Parts and tips are readily available for both units.

[Elecraft] [k2] K2/100 power out on 10m R98 -fixed...
Thanks Don, I did restore R98 to its original 270 ohms (from 1k0) and power output on 10m SSB is back to a full 100W+ The ALC dithering is noticeable, but I'm not going to fiddle any more. Might see if i can just live with it and if not, I'll experiment some more to find a lower value of R98 that damps the loop without reducing my SSB power output too much. I'm not driving an amp with my K2, so it's really not of much practical importance to me - it just jars with my obsessive personality :) What surprised me is that I could still get 90+ W out in TUNE and CW on 10m with the 1k0 resistor at R98 - only power on SSB was reduced significantly (to 30W PEP). In the Elecraft document that describes the R98 mod, they advise checking for the 10m power reduction in TUNE mode, which I did and then I checked it again by keying the rig in CW. Didn't think also to also check power out in SSB before accepting the 1k0 resistor value. I should have thought to do that, but didn't expect it would be reduced so disproportionately. 73, John VK7JB -- View this message in context: http://elecraft.365791.n2.nabble.com/k2-K2-100-power-out-on-10m-R98-fixed-tp5713446p5713446.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
Re: [Elecraft] APF and audio limiting
I think that your understanding of the AGC is probably pretty good. I also think that most people don't know how to set their AGC properly. Yes, there should have been SOME control over the loudness of the other signal, but because the Peak filter brings everything up as it does it can also take an S9 signal and make it sound like an S40 over signal too, even when the AGC is compressing things.. Remember, the AGC is only supposed to bring things to the level of your AF output setting. Therefore if you have your AF all the way up, well, that's as loud as the AGC will put it under Sloping conditions.. It doesn't mean that EVERY weak signal will also be within your AGC Threshold. What sounds loud because of the APF is on doesn't mean that it's opening your threshold control in the AGC. There in lies your problem I think.. What you thought was under AGC control, really wasn't!. What you were actually hearing is proper Dynamic range you should have. So the volume control still comes into play. I'll send you a copy of my AGC tutorial offline. I hope this helps you out some.

Re: [Elecraft] K3 mic gain and bias settings
Hi James, I installed firmware 4.17 then went back to 4.14 yesterday. What I noticed today is that I had to change the mic gain, but in the opposite direction of what you did. I am using a Peltor headset fitted with a HC-4 capsule, and I used mic gain around 20-22, compression 23, no bias, gain high to get 5-6 ALC bars (with compressor turned off, as manual states). Today I had to put mic gain at about 10-11 to have 5-6 bars. I don't know if something is related to upgrading to 4.17 and then back to 4.14, and I don't think it's worth resetting the whole rig, but I had the impression that something more has changed somewhere.

Re: [Elecraft] SolderingStation Selection
Hey Paul. I use the Aoyue 937+ Digital Soldering Station and I love it. I have a review of the soldering station under the name of mekaone at Amazon.com. I have built many kits with it now and I just got done with the Elecraft K1. I think I paid just under $50.00 bucks for it and it had free shipping from Amazon. I also went online and purchased extra tips for it. In my opinion it is going to last me a very long time and I am going to build many kits with it. I just started to purchase the add-ons for the K2 and building them and soon I am going to order the K2 and put it all together at one time. That soldering station was just what I was looking for and much cheeper than the others. O. I forgot to tell you it is a made in China station the seems to be a knockoff of the Hakko but that is no problem for me. You can use the Hakko tips in it but the Aoyue fit best so I just order them.

Re: [Elecraft] SolderingStation Selection
Bob, There are grounded tip soldering stations, and then there are isolated tip soldering stations. Both can be ESD compliant. One can work on live circuits (with caution) with an isolated tip iron - with a grounded tip iron, make certain power is off before applying tip. BTW - the Hakko 936 is a grounded tip soldering station - the Salomon soldering stations that I have are isolated tip. 73, Don W3FPR On 11/6/2010 8:00 PM, riese-k3...@juno.com wrote: wow thats a deal,, isit a grounded tip Bob k3djc On Sat, 6 Nov 2010 18:48:17 -0400 James Sartek2qi@gmail.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

Re: [Elecraft] APF and audio limiting

Re: [Elecraft] APF and audio limiting
Mike, The AGC works at the IF level, not the audio level. What that means is if you crank the AF gain way up to listen to a very weak signal, AGC action is probably not even started because the signal level is at or near the level of the band noise - In other words, the receiver is operation at full gain, all stops removed. Under those conditions, if a very strong signal suddenly comes into your passband, yes, it will be loud simply because the AF Gain is advanced. Yes, the AGC will respond to that new signal - just how much depends on how you have the AGC menu parameters set. If it does cause an AGC response, it will reduce the gain of the receiver, and you will no longer be able to copy the signal at or near the band noise floor. So perhaps what I am saying is that everyone might run their AGC parameters so that all stations, no matter what their relative strengths will have the same audio level - that would cure the condition you have stated - but I do not really believe that is a good solution - for one, it will make band noise the same audio level as the signals - result is noisy K3, and we have been there before. Myself, I prefer to be able to determine the relative strength of various signals by ear rather than by S-meter - that means the strong signals will have greater audio levels than weaker stations - that is just the way it is. Since very weak signals (which is what APF is all about) are well below the level that AGC action starts, when trying to dig out such a weak station, it may be wise to turn off AGC altogether (provided you have set the AF limiter beforehand). With AGC off, the Audio limiter is active to protect you from ear-shattering events such as a strong signal suddenly coming on frequency. An additional benefit to copying very weak signals with AGC off is that a strong signal coming on within the passband will not de-sense the receiver (as it would with AGC on), so you may be able to use the filter between the ears to continue copying the weak signal. 73, Don W3FPR On 11/6/2010 7:46 PM, Mike wrote: Thanks Tom.

What sounds loud because of the APF is on doesn't mean that it's opening your threshold control in the AGC. There in lies your problem I think..

Good Evening, It is time to fall back to standard time. Thus the zulu time changes while the local time remains the same. I checked twice but still may have made a mistake. So please remember the local time you normally use to check in and you (and I) will be fine. Logging operations have been unceasing. Even today there was some activity and I expect they'll be driving by tomorrow starting at their normal 3 AM wake up the world commencement. Most of the drivers have been quite good about not injecting their 200 decibel wake up calls. The first time it happens each morning I think it is an earthquake but after I release my claws from the drywall in the ceiling I realize it is only my friendly log truck drivers insisting it is morning. Luckily they do quit around 4 PM so I can take an hour nap before I make dinner. I think there may be only another two or three weeks before I can get a decent night's sleep again. Propagation has been good and should get even better as spot number 1121 crosses the sun. It has been shooting out M class flares which are ionozing the Heaviside layer. In a few days those blasts will be pointed directly at us insuring we get saturated with solar particles. A day or so after the initial blast our propagation should be very good. It is fun to play on ten meters as it opens more frequently.

[Elecraft] APF et al.
I just want to thank Wayne, Eric, and the gang for taking us beyond the original definition of what a K3 could do. Yes, I know, we're having a little problem getting the APF right, but does anyone really thing it won't be right in the end? I don't. And I suspect there may be a few other goodies in the future. The real point is that this is virgin territory as far as what we were promised on the front end--at least what we were promised specifically! That's what separates Elecraft from the other manufacturers, and I, for one, am grateful. I just hope the rest of you are too. There's been a hint of frustration that APF didn't work perfectly at the outset, and some additional frustration about just how to engage it, but this will most certainly be resolved as practically as possible. The K3 does have some limitations, mechanical or otherwise, but it's still a radio that will keep gaining more and more capabilities. That's what upgradeable radios are all about I think. The implimentation of some of these capabilities may be complicated by other factors, but what the hey! Don't use these improvements if it bothers you that much. I had a very nice Orion II, which I liked a lot, but it just didn't have the potential for improvement like my K3. So I sold it. While Ten-Tec is still trying to get the Orions to perform more or less as advertised, the K3 has zoomed past that plateau. In truth, nobody else out there is really offering a radio that will be stretched--most of the upgradeable capabilities for these radios is devoted to trying to get them cleaned up. Some of you may not agree with this, but I'm convinced that we (K3 owners) have the only radio that will truly expand, as opposed to being one of a series of new and improved models. So, bring on your suggestions for improvement (that's how the APF feature got added), but don't be too critical of the time it takes to get it right. Patience is a virtue. If anyone thinks there is another manufacturer that is doing a better job of enhancing their product, I'd like to know about it. Oh, by the way, most of these enhancements are free, in the form of firmware upgrades. I don't think you are seeing much of this elsewhere.

Re: [Elecraft] APF and audio limiting
Um, Joe, he did not say bring up as you quoted. Are you certain that by saying bring to the level he did not mean bring louder signals *down* to the level of the AF gain? That's how I read it. Your observation about the best AGC operation is excellent for communications work. Often people have AGC working backwards, raising the background noise level to room-filling volume when no signal is present. That's how AGC for AM worked, originally, both for auto and home radios. As a station faded, the AGC raised the volume to compensate, keeping the speaker output the same. So, as one was crusin' down the highway listening to The Wolf Man spin tunes on the AM band one might hear the background noise come up in a weak-signal area, then drop down again as the signal regained strength. 73, Ron AC7AC -Original Message- Remember, the AGC is only supposed to bring things to the level of your AF output setting.

[Elecraft] K3 160m Current High
On 160m, according to my Aston's meter, current drain is about 21 amps when key down @100W. That's several amps higher than other bands. If I run 100W CW for long, the rig kicks down to low power mode. SWR is 1:1. I tried the TX calibration just to see what happensNo change. I had to reduce power to keep it from happening. Also, a question about the K3's DISP of current. When key down, what is it displaying? It's showing about 5 Amps and I know that's not right. Can't find anything in the manual that tells the meaning.

Re: [Elecraft] APF and audio limiting
Since very weak signals (which is what APF is all about) are well below the level that AGC action starts, when trying to dig out such a weak station, it may be wise to turn off AGC altogether (provided you have set the AF limiter beforehand). It might be wise to ask Wayne and Lyle to consider activating the AF Limiter when APF is turned on just to prevent a problem it a strong signal jumps on top of the weak one we're trying to copy. It is not much of a stretch to think that a local might call that weak UA0 on 160 or 5R on 80 while we're running all knobs to the right trying to dig it out of the noise. Looking at W8OZA's AGC test data, it appears that the audio output can vary more than 40 dB from a -140 dBm (MDS) signal to a -43 dBm signal (S9 +30 dB) depending on the user's selection of AGC slope and threshold. If one adds another 10 dB of APF gain, a sudden 40 to 50 dB audio shot can be quite dangerous depending on the initial listening level. In addition, given reports of damage to the speaker amplifier with sudden noise bursts with AGC off, enabling AF LIM with APF *might* prevent some potential amplifier damage. 73, ... Joe, W4TV On 11/6/2010 9:20 PM, Don Wilhelm wrote: Mike, The AGC works at the IF level, not the audio level. What that means is if you crank the AF gain way up to listen to a very weak signal, AGC action is probably not even started because the signal level is at or near the level of the band noise - In other words, the receiver is operation at full gain, all stops removed. Under those conditions, if a very strong signal suddenly comes into your passband, yes, it will be loud simply because the AF Gain is advanced. Yes, the AGC will respond to that new signal - just how much depends on how you have the AGC menu parameters set. If it does cause an AGC response, it will reduce the gain of the receiver, and you will no longer be able to copy the signal at or near the band noise floor. So perhaps what I am saying is that everyone might run their AGC parameters so that all stations, no matter what their relative strengths will have the same audio level - that would cure the condition you have stated - but I do not really believe that is a good solution - for one, it will make band noise the same audio level as the signals - result is noisy K3, and we have been there before. Myself, I prefer to be able to determine the relative strength of various signals by ear rather than by S-meter - that means the strong signals will have greater audio levels than weaker stations - that is just the way it is.

I do not own a precision wattmeter, but a Diamond SX-20C, OHR WM-2, and an Elecraft W2 using the QRP sensor were all in agreement. Here are my results: KX1: I used a four cell 4S1P pack (four cells in series) from Buddipole, rated at 13.2v nominal, 2.3 Ah. I set up my KX1 to call CQ into a dummy load for three hours, using the KX1 memory I usually use which includes a 10-second listening period after each CQ. I left the display on, audio on through headphones but sidetone reduced. My KX1 has the 30-meter board and ATU. Start of test: Voltage 13.2. Power out: 4.3W End of test: Voltage 12.9 Power out: 4.0W At the end of the test the KX1 was barely warm over the PA transistor. My Cellpro 10S charger on the fuel gauge setting said the pack was at 48% capacity. My guess is this pack would power the KX1 for 12-20 hours minimum under real-world conditions, but you can draw your own conclusions. K2: I used an eight cell 4S2P (four cells in series, two sets in parallel) pack from Buddipole, rated at 13.2 v nominal, 4.6 Ah. My K2/10 has every option available in the solar system, including KDSP2. I set it up for maximum energy use, that is all LEDs on, backlight on, receiver performance set to optimum, speaker on. The sidetone was turned down to avoid domestic dischord. This test ran for three hours. Start of test: Voltage 13.2. Power out: 10 watts Amperage draw on TX: 2.36A End of test: Voltage 12.66 Power out: 10 watts. Amperage draw on tx: 2.51A K2 PA section was warm. Charger reported pack capacity at 9% FT-817 Bonus Test I used an eight-cell, 5Ah C-sized NiMH pack. NiMH cells are nominally 1.2V per cell, so this is a 9.6V pack. The pack was made from two spring-loaded four-cell packs bought from Frys, glued together back-to-back with aquarium sealant. They seem to have little knobs and holes that make them fit together fairly well this way, except for the wires that run behind the packs. The batteries are Tenergy brand, available from Battery Superstore or Amazon for about $32 for eight. Other folks have tested the FT-817 with battery packs of various voltages. There is no advantage to using a 12-volt pack according to these tests. I put my FT-817 into battery hog mode: LCD on, rear antenna connector, receiver unsquelched, internal speaker, 5W, internal battery disconnected. Start of test: Voltage: 10.84v Current: forgot to measure End of test: Voltage: 9.08 volts and change under load The test ran for four hours with the FT-817 calling CQ controlled by an external keyer, and the radio was still putting out 5 watts at the end. The Triton charger I use for NiMH packs does not provide percentage of capacity information like the Cellpro 10s does, but I believe this pack was near depletion. Conclusion: So far I really like the A123 batteries, but I don't have much experience with them yet. They are supposed to hold their charge in storage much better than NiMH. As the K2 test shows, they hold their voltage well when discharged. They are very lightweight. At Pacificon when I hoisted the 6.7 Ah pack Buddipole had at their booth I accused them of using a dummy pack with nothing in it. The Triton charger is excellent for NiMH batteries IMHO. It offers three safety settings: 1) total charge time; 2) total charge input; 3) battery temperature. This last one requires an accessory probe that I have not found at local hobby shops. I have the original Triton, I think the current one is the Triton II. The CellPro 10s is only for Lithium chemistries including the A123 cells. It is available from Buddipole, and made by revolectrix www.revolectrix.com It has a balancing harness that allows you to charge the individual cells, or the cells in parallel within the pack without the other cells in series. It can charge two packs simulaneously. The A123 cells, aside from being lightweight for portable QRP use, will handle beaucoup discharge rates--up to 70A per cell. For more information on the A123 cells go to www.buddipole.com, or www.fmadirect.com has a white paper on their tests of the cells. I have no relationship with anybody mentioned in this message. 72, Eric WD6DBM __ 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] firmware 4.14
Delete whatever firmware is in the K3 utility folder then click the button to check for updates. The utility should then automatically download a copy of 4.14 from the Elecraft FTP server.

Re: [Elecraft] KX1 K1 K2 Battery Notes Part Deux--Nanophosphate
Wow. Thanks for all your testing. I have both the 4S2P and the 3S1P battery packs and love them. They charge very quick and are suppose to be much more safe to use than regular LiPo batteries. I once found a video somewhere where someone drove a nail through a pack and kept on using it without fire or anything. That helped sell me. I am using the smaller charger than what you are using. Still nice. It sounds like the 4S2P along with the K2 for emergencies and power outages would be a good setup or even for portable use. I am going to build it with the 100w addition but on battery I can take it down to 10w for regular use till I need to bump it up. Thanks for all your testing :-) 73 de W2EEC Eric __ 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] Day 1: Fried something already?
Today I was finally able to get a real antenna set up to use with my K2. Signals were coming in nicely on all bands so I decided to try and make some QSOs. I have an external amplifier which I used with my old rig, and it's keyed via an external carrier detect switch that sits in- line between the rig and the amp. The switch takes 12v to work. My first mistake may have been leaving the K2 turned on while I changed the cabling to wire up the amp. Before this I was just running the K2 to the antenna through my tuner. I hooked up the coax properly from rig to switch to amp to tuner, and then applied 12v to the switch. I heard a zap in my headphones, and quickly realized that I had hooked the DC up to the RF switch backwards : ( I disconnected it right away. Then I noticed that the noise level on 40m, where I had been tuned, was greatly reduced. I removed the amp and switch from the chain and connected the K2 to the tuner and antenna again. When I tried to tune on 40, I got a high current warning. Same on 12 and 10. The other bands work and sound fine. I don't know how wiring the RF detect switch backwards could have resulted in current getting into the K2. Maybe it was just static, I don't know. So I'm guessing I zapped something in the bandpass filter section of the K2. I've opened it up but I don't see any visible signs of trauma. I did smell a burnt electronics smell right after the mishap, but I'm pretty sure it was from the RF detect switch and not the rig.
