[Elecraft] Seeking external speaker recommendations
I bought the West Mountain COMspkr for my wife's computer to eliminate RFI when I ran HF. They are advertised as RFI-proof and worked for us. I have not tried it as a radio speaker. If you can find an old ham receiver speaker from the 1950's they have a wonderful sound that is hard to match with cheap RS speakers. I am using a ten-inch diameter National Radio speaker which was given me by the father of KL7R-sk. I worked with his son in 1982 and he thought that his son would want me to get some of his old stuff. The National speaker in enclosed in a 12x11x7 inch metal cabinet so a bit large for modern equipment. 73, Ed - KL7UW -- Message: 15 Date: Mon, 25 Oct 2010 08:54:23 -0700 From: Tim Tucker ae...@worldwidedx.com Subject: Re: [Elecraft] Seeking external speaker recommendations To: Elecraft@mailman.qth.net Message-ID: aanlktikgkypuuhddsnb5krn3sq5tsgw7j-26ewwqm...@mail.gmail.com Content-Type: text/plain; charset=ISO-8859-1 I used the SP-20 on my K3 for a while, mainly on SSB.

The volume level issue that bugged me with the SP-20 is also a non-issue, of course.

Re: [Elecraft] HI current 30 meters
Jim, I am not sure about the hang of this forum thing. It is just public email where we try to help each other with Elecraft products. You may have a problem with that wattmeter rather than the K2. Analog metered wattmeters are notoriously inaccurate, especially at low power readings. What range are you using on the wattmeter? The thing about these analog wattmeters (including the much revered Bird) is that they have their accuracy specified as a percentage of the full scale reading. That means if you are using a 100 watt scale and the specified accuracy is 10%, the reading can be off by as much as 10 watts - and that is true *anywhere* on the scale. Also, wattmeters can be frequency dependent. A normal K2 has more gain at 40 and 30 meters than on the other bands. Given the way the K2 controls power, you should have less current drawn for any given power output on those bands. If that is not true, then the most likely place to look for the problem is in the Low Pass Filter for the bands drawing excessive current, or the winding of T4. Also be sure Z1 and Z2 are in place and properly soldered. You might want to check the actual construction against the manual sections that detail the winding of T4 and its installation. If you do not have the manual, you may download it from www.elecraft.com. 73, Don W3FPR On 10/25/2010 11:25 PM, Shamrock wrote: Sorry, Don, I don't have the hang of this forum yet.

Stan, I dunno if it may be related, but I recently had a dead spot in the RF gain encoder. It was recommended that I do a recal (using 20M) with the XG2 and V1.3.10.15 of the utility. An earlier version had a bug where the settings were not saved. Cured my problem. GL 73, Mike NF4L Actually, the main RX is the one giving me trouble, not the Sub; that was Mike's issue. I was trying to duplicate his when I discovered mine. :-) The behavior of my main Rx is the same whether the Sub is enabled or not. I redid the RF gain calibration with my XG2 twice on 40 M and once on 20 M with no change in the behavior.

Re: [Elecraft] APF For K3: progress report
Paul, I would be very happy to just have a live PITCH control, as has been requested a number of times. By live I mean being able to hear the received signals as you vary their pitch, without changing their location in the passband. That would be much better than having to first adjust RIT for a more suitable pitch tone then subsequently having to catch up to it with SHIFT as you describe below. As it is now, PITCH is a sidetone control, not a signal control. When you turn on PITCH the sidetone comes on and the signals go away. To me it is as nearly inconvenient as it would be having the signals go away every time I moved the AF Gain control. The peaking part of APF would be a nice enhancement but it's the live pitch control that I really want. 73, Drew AF2Z On Mon, 25 Oct 2010 23:12:51 -0400, Paul, W9AC wrote: Here's an example of using APF in conjunction with RIT. I normally leave my CW offset at 650 Hz. Some of my CW operating is very weak signal DX on the low bands. When copying extremely weak DX in the midst of static crashes, I need to temporarily shift pitch to less than 400 Hz. Some ops, including W4ZV, have noted that weak CW copy can improve when low pitch is used. I also don't want to tamper with my normal CW offset if I don't need to. By engaging in RIT, I would like to temporally dip the incoming pitch, leave my CW offset alone where I want it 95% of the time, and then adjust the frequency of the APF to match/peak the incoming pitch selected by RIT. If I want to experiment with different pitch settings based on band conditions, I also want the ability for the APF peak to track the pitch I've selected on RIT. That requires a tunable APF. This is precisely what the FT-1000/D gave its users. Of course, the greater the departure of the RIT pitch from the offset may require a wider DSP filter setting and/or roofing filter. But under these weak band conditions, wide DSP and roofing filters are just fine when band activity and adjacent interference is low or moderate. When I'm working early morning grayline DX on 80m or 40m, I rarely encounter strong adjacent stations since conditions are long and stateside is not heard much of the time. Because of this, my overall Rx bandwidth is generally set to 2.8 kHz or greater. Even when weak DX is running split and listening up 2 kHz, there's ample separation to allow a filter settings wide enough to depart a few hundred Hz from the CW offset.

Re: [Elecraft] APF For K3: progress report
Drew, ?HUH? The pitch function that you say you want - change the pitch of a received signal - already exists, just turn the VFO knob, it will change the pitch of the signals which are being received. Normally one would want to tune the desired signal to the pitch which matches the sidetone, not the other way around. Just tap the SPOT button to zero-beat, in fact the K3 can do that automatically (within a limited range). Things that are changed by the PITCH control are the pitch of the sidetone you listen to during transmission, the frequency offset used for transmission and the CWT center frequency as well as the position of the center of the CW passband - it does not change the pitch of signals being received.

Re: [Elecraft] APF For K3: progress report
He wants to vary the pitch without moving the signal in the bandpass, Don. That's a non-issue using a wide bandpass and one of the reasons I don't use narrow filters except on rare occasions when absolutely necessary. With a wide pass band I can just move the VFO (I'm *always* in SPLIT mode so TX stays on frequency.) Like Drew, I often shift the tone of the signal as I'm copying based on the nature of the noise, but it's not practical to do with a very sharp filter when straining to make out a weak signal. Losing the signal at all while juggling SHIFT means missing characters and hunting for it again with uncertain results. Ron AC7AC -Original Message- Drew, ?HUH?

Re: [Elecraft] ...terminate speakers thread? [END of Thread]
Folks - Lets terminate the 'terminate' thread. As per the list guidelines, requests to end a thread, or to complain about a posting, are to be sent to the moderator (me) and not to the list - in order to keep list volume reasonable. In general we do not prohibit repeats of prior threads if the number of posts are small. Frequently a new piece of info does occur. Once a repeating thread gets a lot of posts, I'll end it if there is not something new. Also, when about to post a question, its not a bad idea to first search the Nabble archive of the list at: http://elecraft.365791.n2.nabble.com/ Its a powerful search engine and it will frequently answer your question. Please keep it civil and polite. 73, Eric WA6HHQ Elecraft List Moderator On 10/26/2010 10:10 AM, Bert Craig wrote: Is it not just as easy to simply utilize the 'Delete' key? __ 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] Important List Guideline - Keep it Polite, Respectful and Brief
As per our Elecraft list guidelines, it is inappropriate to post and say someone should -not- have made a posting, or to directly criticize someone for making ANY posting. I've seen several inappropriate posts recently - especially the ones condemning someone for mentioning that they like to sweep the band in TX. Its OK to point out that something is illegal or inappropriate, if done respectfully. It is NOT appropriate to threaten going to the FCC, etc. This is an open forum focused on Elecraft products, their use and other ham radio topics (within reason), but it -is- moderated. It is not a free for all. (See the rec.radio.amateur... newsgroups for an example of a free-for-all.. ;-) In general I try to moderate with the lightest hand possible and not to censor or limit list postings. But that requires your cooperation and thoughtful tolerance of others. I run our daily business at Elecraft, so I may not always jump in a quickly as some would like. I also even get weekends off from time to time ;-) In general, please treat -everyone- on the list as if they were a close friend that you were -politely- speaking to face to face. Presonal criticisms, threats etc are in direct contradiction to the list guidelines. Please also make the -minimum- number of postings possible and please keep them short. It never is necessary to vote 'me too' etc. As always, if you have a concern about a posting, please email the moderator (me). I may not respond to all of those emails directly, but I do read all of them. 73, Eric WA6HHQ Elecraft List Moderator (and modulator..) __ 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] Elecraft email List Official Guidelines 2010b
Elecraft Mail LIST GUIDELINES 2010b For those of you who are new to the list, (and for those of us who have rapidly failing memories..), here is a quick list of things to remember when posting to this list. Please save this for future reference. The most important thing to remember is that this is only a hobby - Let's have fun! The PRIMARY purposes of this list are to provide a forum for discussing Elecraft products, share mods, new ideas, feedback to Elecraft, share troubleshooting ideas etc. 1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to stop advertising spammers from hitting the list.) Any postings sent to elecraft@mailman.qth.net by addresses different from the exact ones it shows as subscribers will be rejected. This includes alias (forwarded) addresses like w1...@arrl.net. If you use an alias to subscribe you must have it as your from: and return address too. Subscribing with w...@arrl.net from your physical address of j...@aol.com will allow you to receive postings, but your postings to the list will be rejected if their from: and reply to: address does not match your subscribe address.. Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to change your list preferences. To unsubscribe or to change your list preferences (digest, no mail on/off etc.), scroll to the bottom of the page and log in with your subscribed email address and the password that was sent to you by email when you subscribed (and sent to you each month). 2. If you want to provide an attachment, .JPG picture or other large file for use on the list, first post it to your personal web page and then post a link to its address in an email to the list. The list strips all attachments to prevent viruses from propagating and to keep the archives at a reasonable size. 3. Please keep the amount of copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies. Always delete -everything- from the prior post except what is necessary to keep your reply in context. Most copied messages can be reduced to one or two sentences to retain context. Remember to delete the email list footer from the previous post and especially avoid copying a long posting and adding 'Me Too!' or something similar. As the number of users on this list grows we need to work to minimize information overload... If a reply is -not- of interest to the list, just reply directly to the posting party. 4. EMAIL OVERLOAD: If you are overloaded by the volume of individual messages on the list, You can view the daily Elecraft list messages for each month in web format at: http://www.elecraft.com/elist.html . These archives are updated hourly and list postings by subject. (the nabble archive looks very useful.) Just click on the ones you are interested in to read. You can also set your Elecraft list email preferences to 'no mail' delivery, which still allows you to post to the list when reading via the digest. You can also change your subscription to the DIGEST version, which sends you a single compilation each day. To change your email list options or to subscribe / unsubscribe, go to: http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the page to log into your preferences page and set your mail options to 'no mail'. 4a. Please make an effort to keep list volume under control by resisting the urge to post a comment on every long discussion thread (CW, Soldering etc.) With close to 6,500 list subscribers volume can quickly get out of control if everyone feels the need to comment. While we do not overly restrict the subject matter on this list, please remember that its primary focus is on Elecraft products, and their use. Many people rely on it for pointers on building and troubleshooting their kits. Other ham Radio topics are OK, but please keep the posts on non-Elecraft topics under control. 4b. *** When emailing about a specific rig or option, please add the rig/option name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) This will be a huge help for those experiencing email overload and will allow automatic filtering based on subject line. Examples: Subject: [K3] Filter Options Subject: [KX1] How to use ped portable? Subject: [XG2] Wow! Its a big help. 5. *** IMPORTANT - PLEASE KEEP ALL POSTINGS CORDIAL. Restrain the urge to email someone admonishing them about a posting. The last thing we want to do is to scare anyone off the list. Overly aggressive postings and negative comments about other posters only serve to scare away new potential list members. Waiting over night before hitting 'send' really helps to put things in perspective.. ;-) If you have a complaint about someone or a thread please email it directly to me ( e...@elecraft.com ) and I'll address it. 5a. Please do not post publicly or privately asking people to stop a particular thread, no matter how long, off topic or
[Elecraft] Top Posting is the official standard for the Elecraft List
Top posting is the official standard for this list, and its especially important for those of us who also read our email on PDA phones, iPads etc. Scrolling though a long thread before getting to the reply text is impracticable on these devices and costs us a lot of time. Reading the response first, at the top, is a huge time saver, especially when you have to read hundreds of emails daily as we do here. We really appreciate your adherence to this. Please also delete all footers and as much of the prior email text as possible when replying to cut down on overall email size. 73, Eric WA6HHQ Elecraft List Modulator __ 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] Can I use an HT mic with the K2?
Having finished my base K2 a couple of weeks ago and spent some time getting familiar with its controls, I'm going to get started on the SSB board assembly this week. However I don't yet have a microphone I can use with it. I have a Yaesu HT with the MH-57 speaker mic, and I'm hoping against hope that I can hack together a cable to connect it to my K2. I realize that a $40 hand mic would be the simpler solution, but in the interest of saving time I thought I would ask if this will work. I already have the connectors and mic cable I would need. These are the pinouts from the mic: http://homepage.ntlworld.com/rg4wpw/vx10.jpg It looks like I might just need to connect PTT and GND, but I'm assuming this is a condenser mic and it might need some phantom power...

[Elecraft] APF suggestions
After gnoshing on this for a while and listening to various posts on using this, I would sure hope that one usage pattern does not have to preclude another. I suggest the following: In CW, I would suggest that DUAL PB turns APF on and off. In CW, I would suggest that the currently non functional LO-CUT-HI function and settings be used to control APF, where SHIFT moves the peak around in the passband, temporarily showing the frequency of the peak, and WIDTH sets the depth of the falloff, temporarily showing the depth of the APC in dB at width setting of current DSP skirts. APF comes on with peak at spot pitch. Resetting RIT via program or RIT CLR should also reset APF peak to spot pitch. Perhaps with config menu options APF RESET with rit or none values = I find it difficult to use RIT to move a very weak station down to the audio peak point in the passband because there is no calibration of my twist of the knob to the rate of change of the station. If he stops transmitting or fades, I can't continue. I may tune PAST him. If I am moving the peak while the incoming frequencies remain constant, I have both the remembered constant tone of the station and the moving tonal center of the peak to compare, so I can center the peak on the station, even if he has stopped transmitting or faded. In a contest operation, having the peak at the same place as the transmitted signal is what is normally needed, and the same way RIT is canceled after a QSO, an APF peak moved up or down needs to be returned to center, so an RIT CLR, button or command, should also return the APF to the spot pitch. Using SHIFT control with light under SHIFT should NOT move APF peak. I sometimes deliberately run a skewed passband rather than move TX frequency when someone trys to put one more frequency in there than will really fit. If I move, I just encourage him, and he will move with me because he's just as bad off on the other side. So I just use SHIFT and WIDTH together to bring in THAT skirt without moving the other. That being the case, I do NOT want the APF peak to have moved. Even though the front panel would not reflect the presence of CW APF, those who really need it and use it will get used to it, and it will get out as yet another great feature slipped in on the firmware. You can make some front panel silk screen adjustment in the future on new K3's. 73, Guy __ 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] K3 APF, etc
Fellow Elecrafters, I am appreciative of all the new and exciting functions which are being or have been incorporated into the K3 firmware. However, I am at the same time hoping someone will develop a laminated sheet summarizing all the new operations and how to use them. I spend almost my entire ham radio time dxing on 80m where the signal to noise ratio is almost always poor.I fear that by the time I remember how to implement some of the new improvements, the weak station will be gone. It reminds me of my new Nikon camera. By the time I have figured out what fstop, ISO, and Aperture settings I need, the bird I was hoping to get a great photo of is in the next county.Many of the good rare weak sig dx on 80 is best worked very quickly before the power squadron arrives. Of course this is all dependent on the K3 usage - contest, dx, etc. Good dx and K3ing in the coming holiday season. 73, Mike K5NU __ 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 For K3: progress report
Wow Don, you really really missed his point. He's trying to say that the Pitch control turns on a tone generator while you're setting it. He's asking that when you push the button that sets the pitch freq. that the tone isn't generated.. That way he can hear the person he's talking to while adjusting the freq. of his IF's center pass band area. Plenty of us wish we had this ability.. There are MANY times when I feel like I want to adjust the tone of the persons signal without moving it away from the IF center, and then having to chase after it with the shift knob..

Re: [Elecraft] K3 Rf gain tracking (main vs. sub)
Contrary to my earlier statement my K3's main RX does show an RF gain non-linearity. I certainly don't see any non-linearity here in either the K3 or KRX3. Using your angle references (RG/RG$ are the RF Gain values reported by the CAT protocol): --- MAIN -- KRX3 -- RG; ADC dBVRG$; ADC dBV CW250 239 0 250239 0 0228 210 - 0.5 231213 - 0.1 45182 164 - 4.2 181169 - 4.2 90130 114 -16 132124 -17 135 90 77 -34 91 86 -35 180 47 46 -51 50 49 -51 CCW 0 02 -85 0 02 -85 The compression at the top end is expected since the -73 dBm signal is well above the AGC threshold until the RF/IF gain is reduced to about the 12:00 (90 degree) position.

Re: [Elecraft] APF For K3: progress report
Sorry, but I did not miss his point. It simply boggles my mind that someone would want to change his chosen sidetone pitch. I have chosen mine carefully - that is the pitch where my mind/ears perceive the CW with the best clarity and comfort over the 'long haul'. I can understand why some might want to make a change of pace during a long contest, and change the sidetone pitch a bit - but for normal operating, I want the pitch to be the same as I have previously selected -- that is the pitch where I can operate CW best. My own choice is 650 Hz, but yours may be different. To change the pitch for a particular QSO seems counterproductive to me. If one is hearing a signal best at a pitch which is not the current one set for the sidetone, I would think that to be an indication that I have chosen the wrong sidetone pitch and I should think seriously about changing to that pitch that I perceive to be the best in the midst of signals on the band. I guess this is part of the reason we hear so many QSOs that are not zero beat. We used to know how to do that very well with separate transmitters and receivers, but in these days of transceivers, I think we have lost that ability - it seems to me that if we can hear a signal within our passband, that we should just transmit and expect to be answered - with no need to zero-beat. Sorry, but it just does not work that way - the other station may have narrow filters on and may not hear us. 73, Don W3FPR On 10/26/2010 5:13 PM, The Smiths wrote: Wow Don, you really really missed his point.

As it is now, PITCH is a sidetone control, not a signal control. When you turn on PITCH the sidetone comes on and the signals go away. To me it is as nearly inconvenient as it would be having the signals go away every time I moved the AF Gain control. The peaking part of APF would be a nice enhancement but it's the live pitch control that I really want. __ 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

[Elecraft] APF comment by Don
Don said: but in these days of transceivers, I think we have lost that ability KR2Q sez: Not if they bother to use the CWT tool ! :-) The huge problem with the K3 isyou have to actually know how to use the great tools it affords you with (in case you can't tell, that is sarcasm). I always used to zero beat (or adjust my xmit qrg accordingly slightly high) by ear. But I have been, and continue to be, totally wow'ed by the CWT and almost never use my ears for that any more, except when I feel the need to confirm that my ears are at least as good as the CWT [they are]with the latter (CWT) being much better for me because it frees up my hearing to focus on receiving CW rather than tuning in by matching tones. When I read about the CWT before any radios were delivered, I thought, you gotta be kidding. Not any more. CWT is just way more efficient (I'm a contester and time matters). __ 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 For K3: progress report
Exactly Don, my point exactly, You DID miss the point. You DON'T understand why someone would want to do it. That's why you can't understand why he's asking for what he's asking. We're not all built out of stone. We don't all want to listen or send our CW at the same pitch all the time. If find that in Noisy conditions I like to lower my side tone down to 380Hz, yet when I'm in a casual QSO I find that I receive better at about 450Hz. When I have 2 stations that are close to each other, and I need the notch to do something for me that it doesn't do as well when I have the pitch set to a low freq. I like to have my pitch set up around 650Hz. It just depends on the conditions, the noise level, the stations that are in the pass band, and how I use the tools that the K3 has to deal with them. IE DSP, NR, NB, RF GAIN, Notch, Soon to be APF, REV CW mode, etc. It's more than just my comfort zone when it comes to the IF pass band, or centering someone in it. We don't all use our radios the same, as I'm sure you already know. For this reason, I DO understand exactly why this person would want to be able to shift his IF WHILE in a QSO, WITHOUT having to interrupt it with the side tone pitch freq. as he's doing so. I've had this happen to me on more than one occasion. As for the Zero Beating, oh boy are you right. People out there have no idea that their side tone has anything to do with their IF Center. They all expect that you have your filter open up to 1KHz when they answer you... I can't tell you how many times people will answer me as much as 100Hz off of my IF center. But they can't all afford a K3 I guess. The new rigs these days don't all tell you when you're in the IF center. The ones that do pretty much have a little orange light that comes on, and most of the people that use these radios don't even understand why that's there.

Re: [Elecraft] APF For K3: progress report
I've suggested to Wayne a few times that we should have a SPOT button that works for the Receive ONLY. IE. when you have the RIT button on, and you hit SPOT it moves the Receive RIT control to center the IF pass band. Just like it does with the main VFO now. This would allow someone to SEND a CQ, have someone answer you off your IF Center, and then auto SPOT them in without having to move the RIT knob. This would allow you to keep put with your transmitter location and then QUICKLY turn that WIDTH knob down to 50 Hz KNOWING with confidence that you're not going to remove them from your receivers IF Pass band. This wouldn't change much about the K3 at all, it would only ADD to the features it has now. I'm not sure why anyone would want to SPOT their rig after someone has answered THEIR CQ off freq. It would just cause the both of you to either loose contact (depending how far off you were) or for the two people to be chasing each other around in circles as each one keeps tuning the other. Of course, when the RIT button is NOT on, the spot would work EXACTLY as it does now. Makes perfect sense to me. For those that wonder what happens when the XIT button is pushed, well, it just acts like it does now, the spot will move the XIT still. The ONLY change is when the RIT button alone is turned on.. then the SPOT works like an AUTO SPOTTING RIT control.. simple, yet VERY helpful for fast tuning and filtering. For those that don't like it, well I guess it can be an option you can turn on and off, just like balance contol etc.. in the Config MENU. RIT = SPOT or RIT = NOR... Not sure why it never made it into the list of things to be added to the rig. Seems like a pretty simple one Or did it? Wayne...

There's another psychoacoustic principle at work here, as well as an electronic one. 50 Hz is a larger percentage of 350 Hz than of 600 Hz. This gives the ear/brain more to work with in discriminating tones (and noise) that are closer in Hz, and it also makes the filter have less percentage bandwidth, which means that, all things being equal, it has better performance than a filter designed for the higher audio frequency. Ah, you say, these are digital filters, so it doesn't matter. Wrong -- digital filters are simply digital emulations of analog filters, and the math that makes analog filters do what they do has the same effect on the emulations! So there's no free lunch -- the digital filters are simply far more flexible, because you're building with bits, not Ls and Cs. :) And there's a third VERY important operational principle, which i think you and others have alluded to -- all of this must be done VERY QUICKLY -- the entire QSO may only last 15 seconds, and you can easily lose a CQ frequency while taking too long to dig a weak one out of the mud. 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
Re: [Elecraft] APF For K3: progress report
I tend to agree. However, if people insist in doing this then as I said earlier if one is going to use a tunable audio filter adjusted to a frequency other than what the Pitch control is currently set for, then the pitch frequency should follow along so that it affects the transmitter as well. If this APF is implemented this way then it becomes the live pitch control being asked for. Any other implementation becomes an unintended RIT control.

Re: [Elecraft] APF For K3: progress report
Wes, I don't think that you're getting it. The APF has nothing to do with TONE, it has to do with Peaking a freq. within the Band Pass filter area. You don't always want to change the tone just because you're moving the peak of a signal.. We're not talking about an IF center peak, we're talking about peaking a PART of the tone you're already listening to... There's no need to move the RIT or the Pitch with the APF at all.. You're just confusing things, and asking for changes that have nothing to do with an APF control knob. You have to separate the idea of freq., tone, and Peaking a portion of a signal... They're ALL different things here. My shift knob sets the center of my IF Pass band, my RIT knob moves people into the tone that my Pitch is set to (yes center of the IF usually), and APF should peak a portion of that IF area that I choose (like a manual Notch filter does, but reverse)... Not move it around. 3 different things here... Does it make more sense to you?

There are MANY times when I feel like I want to adjust the tone of the persons signal without moving it away from the IF center, and then having to chase after it with the shift knob.. His idea would do exactly that.

The pitch function that you say you want - change the pitch of a received signal - already exists, just turn the VFO knob, it will change the pitch of the signals which are being received. Normally one would want to tune the desired signal to the pitch which matches the sidetone, not the other way around. Just tap the SPOT button to zero-beat, in fact the K3 can do that automatically (within a limited range). Things that are changed by the PITCH control are the pitch of the sidetone you listen to during transmission, the frequency offset used for transmission and the CWT center frequency as well as the position of the center of the CW passband - it does not change the pitch of signals being received. Can you be more specific about what you want. 73, Don W3FPR On 10/26/2010 9:37 AM, drewko wrote: Paul, I would be very happy to just have a live PITCH control, as has been requested a number of
[Elecraft] KSYN3 board , free tech special!
I have an early KSYN3 board available to anyone interested. It deteriorated and finally had to be replaced. Any takers?? from S/N 740. -- 73 Allan K7GT __ 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
