[Elecraft] K3 second receiver sound gone
Hi All Thsi happen to me several times now. Been trying to work a dx staion split, and listen to to second receiver to find out where he is working the stations. I do turn off the second receiver, and turn it on again. But after doing this a few times, there is no sound anymore from the second receiver. I only can get it back by turning off the radio and switch it back on Some on has had this problem before? running version 2.78 still. Or should I upgrade?

[Elecraft] [K3] AGC
Hello Folks, Just talking to a friend that has a K3 also and he was asking why the signal gets louder with less noise when you turn off the AGC ? I turned off tha agc when working a weak DX station, and he was right. Made the copy easier and much louder. What is the technical reason for this?

Re: [Elecraft] [K3] AGC
Kieth is correct if the AGC parameters are set high, particularly the slope - that tries to make everything the same volume. If you can recall tuning an AM radio between stations, the noise level between stations gets louder because there is no signal to hold the AGC active, and the AGC is quite aggressive. I did not like the behavior of the AGC with the default settings, I liked the AGC behavior on my K2. After seeing the curves produced by Jack Smith (Clifton Labs), I changed my AGC parameters to more closely emulate the K2. AGC PLS off AGC SLP 002 AGC THR 008 AGC-F 140 AGC-S 010 I like my K3 AGC now - weak signals sound weaker than strong ones and the noise level does not rise as much. Your preferences may vary. 73, Don W3FPR Darwin, Keith wrote: Since AGC automatically turns down the gain when there is a big signal, I'd expect that it would make things quiet. Basically, it adjusts the gain to equalize all signals. Band noise, weak signals, strong signals - all are rendered at the same volume level as they come out the speaker. Turn AGC off and the quiet stuff remains quiet while the loud stuff gets much louder. Overall S/N ratio goes way up. I run my rig with a combination of AGC on/off. I turn AGC on (to squash any loud peaks) then back RF gain down until the noise background gets weak. Now I have a higher average S/N ratio but still have the ear-protection benefits of AGC. - Keith N1AS - - K3 711 - -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of W2XB Sent: Friday, March 06, 2009 7:43 AM To: elecraft@mailman.qth.net Subject: [Elecraft] [K3] AGC Hello Folks, Just talking to a friend that has a K3 also and he was asking why the signal gets louder with less noise when you turn off the AGC ?

Re: [Elecraft] MIC + Line-In Feedback Noise
Bud, Depending on your soundcard you should be able to turn off the monitoring so you don't need to change the Line In level. For example, with the SoundBlaster Audigy 2ZS, open the Recording Control (input mixer), click the Advanced button on the Analog Mix input and select Record without Monitoring. Some Realtek chips include the inputs on the output (speaker) mixer but they are generally hidden (select Options | Properties and show all of the unchecked controls). You can unhide them and make sure the Line In (it may be shown as a color) is muted. 73, ...

I discovered late last night that it was caused by the soundcard Line-In slider position. At first I tried muting Line-In. However, I soon discovered that N1MM would remove the Line-In mute checkbox each time it played a function key Wave file. The only solution is to slide the Line-In slider to the bottom (zero) and forget about the mute checkbox.

This is the truth about QRP vs. QRO, as I see it. ;-) First of all, as so many have already pointed out, it's all good. But, have you ever wondered why the QRP guys seems to be more vocal about QRP than the QRO guys? I'm a QRP guy myself and I can tell you it's because, it's so much fun and for every other reason everyone else has mentioned. Now, why is it that some QRO guys feel that they have to defend themselves against the QRP crowd. I'll tell you why...GUILT. That's right, guilt. If their spouses were to find out that it wasn't necessary to spend mega bucks on rigs, amps, towers and antennas and that they could operate on much less...well you get the picture. :-) Seriously, I think everyone should do what interests them the most.

[Elecraft] [K2] Cw Signal Shift with Filter Change

Re: [Elecraft] [K2] Cw Signal Shift with Filter Change
Is this something that just happened, or has it possibly always been there unnoticed? In any case, a change to the BFO frequency of one or all filters is in order. The condition should be cured by doing a filter alignment. I highly recommend using Spectrogram to do that task. See my website www.w3fpr.com - article on K2 Dial Calibration, the filter alignment info is in part 3 of that article. 73, Don W3FPR KG4UFV wrote: I have encountered a problem with my K2.

[Elecraft] QRP, QRO, and God
I just did that to catch your attention (sorry if anyone is offended). QRP and QRO are all relative terms. It is really just a matter of physics.

Re: [Elecraft] Your Opinion: The realities of QRP vs. QRO
I'm an *avid* QRP-er. Not transmitting so much, *receiving*. Nothing is quite as satisfying as being able to say FB OM, SOLID CPY to a whisper of a QRP signal. So when I have several stations to choose from to call, the weakest is my first choice. If he/she is QRP, then I'll crank down the power to match. But I don't get upset if the other station needs me to QRO a bit for good copy. I like being able to run 100 watts for that reason and it makes the difference more often than not. After all, I'm generally using an Elecraft rig, so guess who has by far the best receiver? There are lots of us. I just happened to be an HF QRP-er. But there are lots on VHF too, running moonbounce and many other weak signal challenges.

I really, really tried not to respond to this thread. It was definitely a troll, but after reading through these messages the hook finally set. I just don't understand the need within the Ham community to create these arbitrary bifurcations. Why QRP vs. QRO? Why SSB vs CW, or straight key vs. paddle vs. keyboard? Why contesters vs. rag chewers? Our hobby is so broad that there is room for all of these differnt viewpoints and different operating styles. Further, there is no regulation, no law, no tradition that states you have to participate in any of these activities. If something disgusts you (a genuine grumpy old man remark), then just avoid it.

[Elecraft] Is the KIO2 line needed with external amp and auto-tuner?
A number of you from the group have really helped me out incredibly!! Huge thanks THIS GROUP ROCKS!!! :~] I run an SGC-237 auto-tuner outside the house. Its the best setup I've ever had, and I don't want to lose its functionality. I plan on locating the external 100 watt amp box for the K2 in a different room. It will be located in a room where I have power supplies and coax line going outside to the auto-tuner. Since I already have an auto-tuner functioning, I'm wondering if there is any need for the RS232 control line from the K2 to the amp box. I think perhaps at minimum, there is an RF-detect signal that must come back from the amp to the K2... if I understand the KIO2 document. Thanks again ALL.

For those interested in ordering this board, which replaces the digital I/O remote board on the KIO3, its available for $20 on our parts and mod kits order page: http://www.elecraft.com/order_form_parts.htm#K3%20Parts And our complete listing of K3 app notes and mods is: http://www.elecraft.com/K3/k3_app_notes.htm 73, Eric WA6HHQ Joel R.

Re: [Elecraft] Is the KIO2 line needed with external amp and auto-tuner?
Duane, Not to put a damper on your plans, but to serve as a caution. The AUXBUS signal is a one wire communications channel between the K2 and its options. If the length of the cable becomes too long, there will be significant delay between a query and a response on that AUXBUS signal which will produce errors - the first may likely be that the remote option (KP100/KAT100) will not be recognized by the K2. Those signals are not all RS-232 levels, they are internal K2 signals, and that is why the connector on the K2 is labeled AUX IO - do not connect a standard computer serial port cable directly to the K2, it will cause damage to the K2. If I recall, the signaling has been tested out to 6 feet of cable, but it sounds like your plans will require more cable length than that. Please let us know how long a cable you have used and whether it performed without problems, I am certain several others would like to know too. 73, Don W3FPR dw wrote: A number of you from the group have really helped me out incredibly!! Huge thanks THIS GROUP ROCKS!!! :~] I run an SGC-237 auto-tuner outside the house. Its the best setup I've ever had, and I don't want to lose its functionality. I plan on locating the external 100 watt amp box for the K2 in a different room. It will be located in a room where I have power supplies and coax line going outside to the auto-tuner. Since I already have an auto-tuner functioning, I'm wondering if there is any need for the RS232 control line from the K2 to the amp box. I think perhaps at minimum, there is an RF-detect signal that must come back from the amp to the K2... if I understand the KIO2 document. Thanks again ALL.

Re: [Elecraft] Alternate Knob for K3 VFO B - update
Having read several sets of emails regarding substitutes for the B knob over the past year, I thought I could contribute by making a suggestion. Since this is the first posting I've done to the forum (or any forum), I have no idea whether this will reach its intended audience, but here goes: Several years ago, I added a crank to an FT-817 main dial. I was unaware of any substitutes, so I just made my own. You can do the same with the K3 B dial. All you need is a very small screw, about 2 x 10 mm, and a ferrule to fit around the end of the screw to create a rotatable knob. I have downloaded (I hope) 2 images of the 817 dial I modified (See http://n2.nabble.com/RadioPhotagsWBG-f2438356.html; and http://n2.nabble.com/embed/f2438356;). For the 817 knob, I used a very small flathead screw, 0.8 x 8 mm, and a plastic ferrule from my 50-yr. old junk box. I drilled into the mostly plastic 817 dial using a pin vise and drill bit slightly narrower than the screw, then carefully turned the screw into the hole to force threads into the plastic. Assuming all K3 B dials are the same, you could drill about 6 mm into the plastic before hitting the metal core. (my K3 dial is so heavy, I wonder if the Elecraft crew used depleted uranium.) I don't mean to imply there is anything wrong with the K8FF modifications, but If you need crank right away, this could do it. The 817 was so easy, I'm thinking of putting these cranks on my K3 Shift, Width etc., knobs. Hi, Hi! I hope this helps. I received several replies to my question about an alternate knob for VFO B on the K3. It appears that quite a few people have switched out that knob ... some with a K2 knob, others with one of the larger Yaesu knobs, a few with varying military or commercial surplus knobs they were able to find. The general feedback was that the FT-817 knob was probably NOT the way to go. I also got a very nice reply from K8FF, the fellow who makes the finger dimples and the FT-817 Kranker knob. With his permission I'm quoting the relevant portions of his message below. 73, Dave AB7E Bill, WD8MNG -- View this message in context: http://n2.nabble.com/Alternate-Knob-for-K3-VFO-B---update-tp2431356p2438678.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

The primary issues with cable length are noise pickup and capacitance. Both can be helped a lot by using CAT5 for the serial connection. Dedicate one pair to each signal line, and connect the return of each pair to the connector shell, not pin 5. CAT5 is very low capacitance, and the very high twist ratio rejects noise and RFI. Going to the connector shell bypasses the pin 1 problem at each end. I work in pro audio, and we often have sound equipment in racks buried in the bowls of the building, but need to remote control that gear for tuning the system from within the auditorium. Doing what I've described, we often use serial over 200 ft of CAT5 at very reasonable data rates with no problems. BTW -- the RS232 standard originally quoted cable length as a limit, but was later revised to define it on the basis of capacitance. 73, Jim Brown 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] Alternate Knob for K3 VFO B - update

Re: [Elecraft] K3 Upgrade Kit Question
Hi Joel: The upgrade to improve RF immunity affects two different I/O boards. The board with the audio connectors on it and the board with the DB9 and DB15 connectors. The ALC mod kit for $20 is a Rev B version of the board with the DB9 and DB15 connectors. And I don't know if the RF immunity mod was done to that board or not. Someone who has the Rev B board in front of them would have to comment on whether choke L1 has been jumpered across (or perhaps removed entirely). 73, Mike K2MK Joel R.

The famous Army BC-611 handy-talky you mention is part of the SCR-536. The Navy also had low power battery-powered portable MF/HF sets in the form of the MAB and DAV chest-pack sets. All of these operate at about one-third watt output into a short whip antenna. They are crystal-controlled (receiver and transmitter), operating from about 2 or 3 MHz to 6 MHz. They had 5 to 7 vacuum tubes, and utilized superheterodyne receivers and plate-moodulated transmitters. The Army sets had a receiver RF amp, but short antennas. The Navy sets had no RF amp, but longer antennas. I doubt there was ever much DX with these sets. I recently fired up my BC-611-F on 3885 kHz and heard a surprising number of AM stations at night.

Re: [Elecraft] WWII-era US Military MF/HF QRP rigs (OT)
As a communications sergeant in the 40th Armored Division of the California National Guard in the late 1950's we were still using WWII vintage AN/PRC-6 hand helds. They were used by the infantry on foot traveling with the tanks (yes, they traveled together. It's easy for one person on foot to kill a tank when in towns or wooded areas when they can't swing the turret. Just climb up with a sachel bomb and then walk away. That's why in the war films you see infantry walking alongside the armored vehicles. The PRC-6 was how the infantry communicated with the soldiers inside.) Anyway, getting back to merely off-topic, the PRC-6 operated A.M. crystal controlled in the Amateur 6-meter band which was shared with the military then. The PRC-6 used the sub-miniature pencil tubes (because the tubes were about the diameter of an ordinary lead pencil) and made perhaps 100 milliwatts output with fresh batteries. That was FB for the very short range communications they needed. One day on duty in Southern California I was holding a PRC-6 waiting to do a radio check with another guy in a vehicle when I heard a W0 in Colorado start calling CQ right on my frequency. So I answered him using my Ham call. He came right back. I don't recall the signal reports but we chatted for a while until the armored vehicle came up on frequency. The PRC-6's antenna was a 1/4 wave ribbon whip sort of like a metal tape measure but the only ground was me holding the thing. We were talking over a range of about 700 miles, me running 100 MW A.M.

In the late 50's... at the peak of the most humungous sunspot cycle seen since Guglielmo Marconi was in diapers. You guys can have your DXCC, WAS and whatever certificates. I just want to see another sunspot cycle like that!

Re: [Elecraft] NorCal Doublet
Frank, I do not know of a source, but contrary to other posts, the Norcal doublet used actual computer #26 IDS wire (not rotator wire). Don't get me wrong, the rotator wire will work, but it will not be as lightweight as one constructed of computer flat cable as the NorCal doublet was. If you want an antenna that will perform just like the NorCal doublet, use any kind of wire for the radiator, cut to 22 ft. on each side and feed it with 300 ohm ladder line. I use the #22 teflon wire offered frequently by N2GO on the QRP reflector for the radiating element, and use either lengths of the same N2GO wire twisted for the feedline or I use the 300 ohm ladder line. The teflon insulation is nice because it does not stick to tree limbs and if tangled is easy to untangle because of the 'slippery' nature of teflon. The antenna is the same as the NorCal doublet, but the wire is different. 73, Don W3FPR Frank MacDonell wrote: Does anyone know where one can purchase the wire for the NorCal Doublet Antenna (4 strand computer ribbon wire)?

Re: [Elecraft] [K3] AGC
Don: Your setting are so different from mine. I tried yours, and now I have a brand new K3. Thank you. 73, W1TF, K3 #696 , K1 # 1423, gets used once in a while. --- On Fri, 3/6/09, Don Wilhelm w3...@embarqmail.com wrote: From: Don Wilhelm w3...@embarqmail.com Subject: Re: [Elecraft] [K3] AGC To: elecraft@mailman.qth.net Date: Friday, March 6, 2009, 8:22 AM Kieth is correct if the AGC parameters are set high, particularly the slope - that tries to make everything the same volume. If you can recall tuning an AM radio between stations, the noise level between stations gets louder because there is no signal to hold the AGC active, and the AGC is quite aggressive. I did not like the behavior of the AGC with the default settings, I liked the AGC behavior on my K2. After seeing the curves produced by Jack Smith (Clifton Labs), I changed my AGC parameters to more closely emulate the K2. AGC PLS off AGC SLP 002 AGC THR 008 AGC-F 140 AGC-S 010 I like my K3 AGC now - weak signals sound weaker than strong ones and the noise level does not rise as much.

[Elecraft] [K2] Progress on my K2 assembly S/N 6698
Just completed the 40m alignment and all is working perfect. Now onto stuffing the rest of the RF board components...Hope to have the radio complete this weekend. I have to assemble the DSP kit yet, then install all the options after alignment of the other band stages. I have the NB, SSB 60m/XVTR kits built already, plus all the headers installed. Took a bit to figure out I needed to jumper this that pin on the headers since I installed the headers instead of the W jumpers as I built the RF board up through the 40m stage. This is the 10w version. I picked up the AN762 linear amp board from FAR at the Orlando hamfest to build an external amp for those occasions where I want to run more than 10w. Building a 14mc IF LF/MF transverter once the radio is complete. This radio will see lots of use on 600, 1750 2200 meters. I have to say this is one super easy radio to build. The enamel wire is a breeze to strip/tin with some rosin and a 80w iron. Piece of cake winding the toroids with those procedures and pictures in the manual. More info later...back to the bench I go!!! This is tons of fun.

[Elecraft] K3 LO Cut adjustment
It is a really good tool made very ordinary with the degree of adjustment allowed. I cannot but wonder what the thinking was when the decision was made to adjust by a factor of 10 instead of a finer degree of adjustment of LO Cut. I am curious if others have found themselves in the position of having to settle for eg. setting of 10 or 20, when a setting of 15 would be just about right on the money. My ears are the only ones I have and they are not now as they were a long time ago. I have tried different settings many times and still I come back to the lack of fine tuning available on the LO Cut. The width and Shift work ok for my ears but the LO and HI Cut adjustments are just too wide for each increment. Maybe I'm picky, but, it is one of those little things that annoys me to the point where I give up and go inside and scream at the TV out of frustration. What, if any, are the chances of improving this function?
