Re: [Elecraft] KXPA-100 to ICOM PW-1 amplifier
Sorry, my error. You CAN use ALC to control drive power, but it should not be used for that purpose. If you set the transceiver to 100W and let ALC reduce it during normal operation, you generate trash in your transmitted signal. Prior to replacing my Icom transceiver with the K3, a neighbor complained that I had bad key clicks. Turning down drive power on the transceiver, rather than relying on ALC, substantially improved my signal. This was using a PW-1. PW-1 uses ALC for protection. Unless I misunderstand, running the PW-1 without ALC, even directly from a KX3, may not be a long term reliable solution. 73, Josh W6XU On 7/29/2014 8:05 PM, Charlie T, K3ICH wrote: Well, yes it is when connected to an Icom transceiver it is used precisely to control drive power. __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] KXPA-100 to ICOM PW-1 amplifier
Just to clarify... use of ALC with the PW-1 is not to adjust drive power. That's a bad practice. You MUST use the ALC line because the amp uses this as a primary means of protection. Without ALC, a fault condition can damage the amp. 73, Josh W6XU Well, yes it is when connected to an Icom transceiver it is used precisely to control drive power. I have the PW-1 connected as recommended in it's manual to an IC-7600. My output control is set for about a hundred watts barefoot and 1 kW when the amp in enabled. The output power when driving the PW-1 is far less than 100 watts and the only thing controlling the drive is the ALC line. Besides, I thought that's exactly what I said. The proverbial fly in the ointment is that the I don't believe the KX3 HAS and ALC input.

Re: [Elecraft] KXPA-100 to ICOM PW-1 amplifier
Josh, If one insists on using ALC for amplifier protection, set the level well above that which will cause ALC to reduce the driving transceiver's power during normal operation. Most well designed amplifiers provide adequate self protection and should not rely on ALC to reduce the drive in the case of a fault. If the amplifier design relies soly on the use of ALC to provide fault protections, I would call that 'risky design'. If it is the primary means of protection, that is an example of poor design IMHO. To rely on an external device for such protection is to rely on a device that also is subject to failure - in other words, poor design IMHO. 73, Don W3FPR On 7/29/2014 9:54 PM, Josh Fiden wrote: Just to clarify... use of ALC with the PW-1 is not to adjust drive power.

[Elecraft] Fw: K3 - noise reduction query
Here is a message from the Elecraft GURU that may help. From: Lyle Johnson Sent: Friday, July 04, 2014 9:47 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 - noise reduction query There is an incredible range of characteristics to unwanted "signals" that we loosely call noise. The K3 has an array of tools to fight noise, and sometimes they work well in concert and sometimes better alone. There is an IF blanker with adjustable threshold and pulse width - but some impulse noise ay wider than the widest available setting and this is likely to include lightning-based pulses. There is also a DSP-based "IF" noise blanker. There is a noise reduction, or denoiser function available with a wide range of settings. AGC settings can also affect the operation, and apparent effectiveness, of the DSP-based noise reduction and to some degree the noise blanker. There is a pulse function in the AGC system that you can enable or disable, These settings may all interact to some degree. As the station operator, you have a complete communications system to manage: antenna, feedline, QTH, desired path, time of day and so forth. The radio is one component of the system. The K3 offers a range of tools for you to use, but in the end there is unlikely to be a "magic" setting that works for everything. If there were, we would have set that at the factory for you (and probably removed the settable "knobs" for you to adjust)! I suggest that if you are having a severe noise problem, you experiment with the various settings - including AGC threshold and slope and PRE and ATT settings as part of the tool set - and note which work best for you in your system and under which types of noise and mode(s) of operation. You won't hurt anything, and you may learn a lot. And, yes, some radios may work better than others with some types of noise under some circumstances. 73, Lyle KK7P (still learning after all of these years...) __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] [K3] Noise Blanking, all-mode squelch- any strategies for settings?
I'll try. The short answer, in case you're not into an explanation is: "It all depends on your circumstances, the character of your noise, the strength of the signal you're trying to copy, how much distortion you're willing to tolerate ... and sometimes the phase of the moon." No one can give someone else a set of numbers that will work in every case. The K3 has two Noise Blankers and a DSP Noise Reduction feature. Noise blankers do exactly what their name implies ... when a sharp noise pulse comes along, they simply punch a hole in the signal [mute the receiver] for a short period. The adjustable things are generally the length of the "hole" and some form of threshold setting that determines when it decides it's a noise pulse. The K3 has one hardware NB at the 1st IF [8 MHz] that works essentially like any other NB. It also has one in the DSP firmware that operates on the "number soup" from the ADC. It too blanks the signal for variable times and under variable conditions ... because it's doing it with arithmetic and not hardware components, it can be somewhat more precise. Noise blankers are effective against repetitive short pulse noise such as ignition noise from a vehicle [not nearly as common as 40 years ago] and precipitation static. They are *not* very effective against power line hash although sometimes they'll knock it down some if it has a short repetitive component. They are not effective against T-storm static much at all. Obviously, punching holes in the signal distorts it and the longer the holes, the more distortion. As you increase the aggressiveness of the NB, you'll start trading noise for distortion, so the basic rule is, use as little as possible. They're not magic. Noise Reduction on the other hand all happens in the DSP. There are various approaches to it, in the K3, the DSP algorithm builds a variable filter on the fly to enhance the desired signal, thus appearing to lower the noise. How well it works depends on it's ability to identify the signal components separate from the noise. I have found it to be much more effective on SSB than CW with very narrow bandpass. I rarely operate SSB so mine doesn't get much use. The "aggressiveness" of the NR is adjustable in the K3. The first half of the available settings operate on the signal and what you hear is the result. The second half mix in some non-NR'd signal with the output. The general rule for NB [as little as necessary] sort of applies to NR too, and again, no one can tell you exactly how to use it. That's a lot of words to say, "NR isn't magic either." 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 7/29/2014 9:48 AM, Arlen Fletcher wrote: Greetings Elecrafters, I’m new to the K3 (and HF in general), and I’m trying to sort out how to get useful results from the Noise Blanking (NB) features.

[Elecraft] K3/Mini 0
Got my new K3 Mini 0 today. Since I didn't order the cable, I made one to take the DB15 to the TTL only. I'm using existing cables that I had already made to connect the Remote Rig box to a keyer, microphone, and PTT footswitch, and the Mini works fine with my Remote station. When it arrived, I checked and I thought it was on firmware 4.83, which means I needed to upgrade the firmware but I'm not sure how to connect the Mini to the computer to get the upgrade. I tried the USB cable, and it created two comports, but the K3 Utility doesn't see the Mini when I attempt to use either of the Comports. I had already hooked up an RS232 cable to the Remote Rig Control box at Com1, and N1MM Logger software is happily communicating with the Mini, but again, the K3 Utility 1.13.5.9 doesn't see the Mini using that comport. I know the firmware updating recommendation is not to do it through another piece of equipment, but if the K3 Utility doesn't even see the Mini its not an option. So, how do I update the firmware? Since I went through this, I unplugged the TTL cable from the RR box, and now the Mini shows me the actual firmware that it has installed is 4.86, so no upgrade is currently needed, but I will probably need to update it sometime in the future. I was quite disappointed in the manual, particularly in what it didn't cover. I already have a working remote station, so I don't need all the diagrams that show how to hook up a remote station using the RR boxes. I do need more information on the Mini itself. On the left side there are 3.5mm connectors for Spkrs and Mic; are those stereo or mono jacks? The Mic connector- would that be selectable in the firmware as the RPL, and the front 8-pin connector the FPL? On the right side, we have the USB port and the DC in. Both self-explanatory, given that cables are supplied for those two. On the back, we have key, paddle, and ptt jacks. Are these stereo or mono jacks? If I had the cabling from the DB 15 to the Aux/Mic and the I/O inputs on the Remote Rig, could I then connect the computer keying to key, my paddle to paddle, and a footswitch to the PTT, and the connections would then be passed on to the Remote Rig box? Is there any way to CW key the Mini by sending CW on the DTR line and PTT on the RTS line, via N1MM? I've played with this for a little while, but haven't found a solution yet. Thanks for assistance with any of the above matters.

Re: [Elecraft] [K3] Noise Blanking, all-mode squelch- any strategies for settings?
Hi Arlen - I, too, seek just such a general guide for using the various noise reduction features on modern transceivers, but have yet to find one. Transceiver user manuals are typically pretty lean on real world explanation - they enumerate the features, point out what button or knob makes an adjustment, but there is a paucity of explanation on how and when to use those features on the air. This is a problem with many other features on these radios. Moreover, the manuals rarely explain how an one feature relates to the another noise reducing features, including the NB Noise Blanker, BW Bandwidth, PBT Pass band, RF-Gain, and other controls, which, when used together, work pretty well. Modern transceivers like the K3 have different tools for different problems. I recommend a detailed web search for articles and comments that explain how these various systems work, in general, and which work best on what types of noise, in particular. Eventually, you will assemble enough information to better understand how these features operate and interact. I have yet to find a single, comprehensive explanation in real world terms... and I have looked! Sometimes a combination of adjustments will get the click. Sometimes nothings gets the click. This research will pay dividends and you will learn about the K3 and other radios as well. In any case, there are no free lunches, these tools alter incoming signals, causing, in turn, some level of distortion and impose unwanted digital "artifacts" - hopefully resulting in greater intelligibility, but with some fallout or deleterious impact in the signal. You trade off one for the other, and hopefully don't go too far and make things worse, which is easy to do. Used in moderation, audio quality is sacrificed to some degree to achieve better intelligibility. The first thing you must determine is which type of noise is tackled by each noise reducing feature. For example, and it varies from rig to rig, but generally (speaking in very general and not scientific terms lest I generalize too much) - DSP NR attempts to reduce random noise like atmospheric static and general hiss which covers a weak signal. The NB Noise Blanker typically reduces repetitive pulse type noise like ignition sparking, and some NB circuits are geared more to reducing the heavier pulsing of radar systems, like what SW listeners call the Russian Woodpecker. The AN or Auto Notch seeks out and removes one or more constant tones, like when someone is tuning his antenna tuner right over your QSO. A manual notch does that manually, you gotta adjust it out, frequency and bandwidth are user selected. The PBT or Pass band Tuning control allows you to shift the receiver pass band left of right to avoid a problem signal on one or the other side of the signal you want. You get less of the desired signal, but maybe none or far less of the offending signal that way. RF-Gain can often be used to lower signal and noise (so to speak) and you end up with less noise and less signal, but maybe a better signal-to-noise ratio where noise is less noticeable against the resulting signal volume. You should research how each one works, on transceivers generally, and the K3 in particular, and EXPERIMENT with each individually and blended with others for best advantage, each situation may vary from another in some way. There are few concise explanations, so it may take some time to assemble a comprehensive explanation, but the effort will pay dividends on your time investment. Good luck. - K8JHR - __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] [K3] Noise Blanking, all-mode squelch- any strategies for settings?
As no one has responded yet, I'll throw in my most recent experience: I assume you meant to say Noise Reduction - a mistake I made a couple of months ago. Although I was quickly informed of my mistake, I never did receive any really useful information regarding the many settings available on the K3. My specific question involved thunderstorm static - for which the K3 is no better than any other rig. In fact, it handles the noise less well than a couple of my other rigs. Hence, I do not use the K3 during high static conditions. Be aware that many answers will be sent to you via direct email, rather than on this reflector. Should one of them be informative, please post same - in order that we may all learn.

Re: [Elecraft] Copying Configurations
The memory editor (for KX3/K3) is the best compromise. Ops may use it to transfer memories from one unit to another. This program does not change configuration, just memories. As Matt said, transferring the entire config from one unit to another would change the target's parametrics and might make it unusable, requiring recalibration. The config section of the K3 and KX3 utilities registers the serial number and a CRC (checksum), and the config image may only be restored to the original radio. 73, matt W6NIA >No, it is not possible to copy configurations from one K3 to another. , >Matt VK2RQ Matt Zilmer, W6NIA www.elecraft.com 831-763-4211 x129 __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] [K3] Noise Blanking, all-mode squelch- any strategies for settings?
Greetings Elecrafters, I’m new to the K3 (and HF in general), and I’m trying to sort out how to get useful results from the Noise Blanking (NB) features. I’m looking for strategies, tips, techniques, etc. for selecting the settings for NB. With over 14,000 possible settings between the IF NB and the DSP NB (according to KE7X’s K3 book), I find myself getting overwhelmed and I give up on NB. Honestly, I can hear very little difference as I go through the various NB settings, so how am I suppose to choose the ‘right’ one? I operate SSB almost exclusively, and I don’t use all-mode squelch - but I need to experiment with this. I’d appreciate hearing your take on squelch. What’s your secret recipe for picking NB settings that work? Thanks! 73, Arlen, AA7F __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] KX3 RF connector
Yes I know the RF to RF board or ATU connector doesn't turn (much!) as the chassis hole is keyed but after about 2 years use attaching and disconnecting bnc there must have been some movement as on EU037 Garpen as SM7/M1KTA/P over the w/e I was getting odd RF drop outs/ vswr all over the place etc (using #1082). Now I travel with a spare KX3 for DX and contest so swapped out the KX3 (spare #2334) and carried on (RSGB IOTA contest) after contest had a look and put it down to the RF lead... the repeat use of connections that apply even a slight rotation to the radio had fractured the lead from the centre pin of the BNC to the flying lead. Visibly it looked fine but the only thing that was keeping it in place was the little bit of black shrink wrap. At first thought was the BNC centre pin but it wasn't as worked fine with the other radio. Cut the shrink wrap back a bit and the lead had separated from the socket at the place where the solder started, it literally fell out . culprit found. Now back home I'll remake the RF connector. Using a piece of RG316 or RG174 with a little strain relief loop. Yes the space is tight! My #1082 is about 2 years old and it has seen a lot of use/abuse I will admit. Anyone else had a similar issue? 72 Dom M1KTA __ 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 Message delivered to arch...@mail-archive.com

Hi Gerry, Thanks for the info. As the ARRL data shows, phase noise performance of the K3 that's working right is quite a bit better than any other modern rigs out to 1 MHz, but that's as far as ARRL's published data goes.

Re: [Elecraft] Copying Configurations
No, it is not possible to copy configurations from one K3 to another. In my view, bypassing the serial number check would not be straightforward (I would guess that Elecraft use checksums to protect the integrity of the files). If you somehow manage to achieve this, then yes, it will cause problems with the target radio, and the radio would need to be recalibrated. 73, Matt VK2RQ > On 30 Jul 2014, at 1:31 am, "K5HM" wrote: > > Is it possible to copy the config from one K3 to another?

What's between Hop #1 and Hop #2? A wire that is unique to Chuck's connection -- the wire from him to his ISP (and "wire" could be cable). This is a great example of why I said don't ping something too far away: if that wire is a little bit flaky, it'll show a lot of packet loss.

Re: [Elecraft] K3 Commands
Hi,The first thing you will want to do is to reset the equalizer to 0 for all bands. Command: MN008;SWT53;MN255; Next you issue the following: MN008; which selects the equalizer menu, then you issue the equivalent of a tap on a button for the particular equalizer band you want. So for the 50hz band in the equalizer you would normally press the "1" button which is a SWT11; then you issue as many UP; or DN; commands you need. So to raise the 50kHz equalizer by +5 you would do the following MN008;SWT53;MN255; MN008;SWT11;UP;UP;UP;UP;UP; For the other bands in the equalizer you can look up the SWT table in the programmers reference for the buttons 1,2,3,4,...etc. Note: Issuing many UP; commands without delays, will not necessarily always work for the equalizer. 73's Tom va2fsq.com On 7/29/14, ab2tc wrote: > Hi all, > > If there is a command to *set* the RX equalizer I am unaware of it.

Re: [Elecraft] WRTC 2014 - Congratulations, Elecraft!...(and firmware update)
I was a WRTC 2014 volunteer responsible for overseeing 4 different stations. Of the 8 radios at these stations, 6 were K3s. Before the contest started, we did have a significant issue with phase noise interference from one of the K3s on 15M when that station was beaming toward the adjacent station (also receiving on a K3). The interference made 15M unusable at the adjacent station. When we tested with the non-K3 from the same location with the same beam heading, the phase noise was not a significant problem. If we reduced the K3 output to 30 watts, there was no problem. Fortunately, we were able to change out the original K3 with another K3 and that significantly reduced the problem. I have used my K3 at a 160M multi-op station and recognzie how important it is to properly set up the AGC parameters to allow two radios to be on the same band. Since we were able to resolve the problem to the competitors satisfaction, I didn't probe any further into the setting of the K3s.

But are you seeing that packet loss reflected on every hop past that point? ISP routers are often configured to rate-limit or block responses to ping and traceroute requests since both require the router to actually process the packet with their CPU rather than simply forward the packets which is done via specialized hardware ASICs. If you see packet loss at one hop but you don’t see similar packet loss on every hop from that hop on, chances are you’re running into rate limiting or blocking and it’s not impacting your actual packet forwarding. This is also a reason why Lynn’s suggestion to pick a local ISP router may work they way you’d want either. 73, Bob N2KGO __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] KX3 - selfprogramming macros - why does PF1 work ok, but not PF2
I have made a macro assigned to PF1 which sets the KX3 in split mode with subrx. The macro is followed by some commands which reprograms PF1 to remove the split and revert to single RX by setting PF1 to macro 2 - this works fine and allows PF1 to both turn on and turn off split. Macro 2 does the reverse and reassigns macro 1 to PF1 - thus PF1 works as a toggle between split+sub rx and no split. For PF2 I am trying to make a similar setup to allow two macros on the same button, the critical commands are; To reprogram to macro no 4 (just the reprogram steps shown): MN110; SWT28; SWH26; MN255; Or said differently; enter macro x, tap 4, hold PF2, exit To reprogram back to macro 3: MN110; SWT20; SWH26; MN255; (enter macro x, tap 3, hold PF2 and exit) For some reason I am not able to make this work on PF2, the same sequence works fine on PF1 but I am not able to make it work on PF2. I have similar commands on my K3 and they works on all programmable buttons. Can anyone spot an error in my logic or have I met a bug in the KX3 firmware? 73 de Olaf - LA3RK __ 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 Message delivered to arch...@mail-archive.com
