Re: [Elecraft] K3 Split Release
On #202 with latest firmware, when I am in split mode and then turn on the SubRx , the K3 stays Split in all modes (cw, ssb, AM). I have to tap BSET button to take it out of split mode.

Re: [Elecraft] K3 Mini plug/jack mis-contact
Aki, There should be no difference in the various mini-plugs as long as they are the 3.5mm type. If you are using a 2.5mm, it might work for a while, but will be loose in the jack and will not make good contact. If you do have a 3.5mm plug and it is loosing contact, check to be certain the jacks protrude through the rear panel sufficiently. If the KIO3 module is not properly seated, the jacks will be recessed and will cause the problem you seem to be having. 73, Don W3FPR a.yoshida wrote: I sometimes find that mini plug/jack on the back panel makes mis-contact.

[Elecraft] AL-811H Amp and K3
I will be picking up an AL-811H soon. I was first licensed in 2001 and I have never had an amp. The 811 requires a 15ms delay, and I noticed that the firmware now supports up to a 20ms delay, so I should be good there. The 811 documentation talks quite a bit about the use of ALC, and the K3 documentation talks quite a bit about NOT using ALC. I'm not sure where to go with this. Anyone using a K3 with an 811? Do I need to use ALC with it? I am trying to get everything ready for the upcoming contests, so timing is becoming an issue. The current manual says to see the website to see if you need the mod kit. The website says to see the mod kit manual, to see if you need to the mod kit. The manual does not say anything about how to determine if you need the mod kit, so I assume that if -12v ALC is needed, the mod needs to be done. Is this correct? I do not see any mention in the K3 documentation about connecting to amps. It looks like the key out is used to key the amp. The manual says up to 200v DC @ 5A. The 811 documentation only mentions 12v, and gets grounded for keying the amp.

Re: [Elecraft] AL-811H Amp and K3
David, I run the Al-811 (3 tubes otherwise the same as the 811H) with my K3 and interface is very easy. There is no need to use ALC just adjust the K3 power output so you are not overdriving the amp. With my setup that's around 60- 70 watts out. You just need a simple cable with RCA plugs as the keying line and you are good to go.

[Elecraft] K3- How Robust iis the Tuner?
Well, I finally got a minute to turn on the K3 this weekend. Flipped over to 40 meters and set everything up for some RTTY contacts. Tuned the tuner and let out a call on RTTY at 100 watts during the sprint. Forgot that I had the Big Tuner in the line set for 20 meters. Of course the SWR was off the scale but the K3 had tuned it to 1:1. After the first transmission, I realized this were not right looking at the external meters and quickly change things. The K3 was working OKbutI did smell a stink. Smelled like a component got hot. Now then, the K3 seems works OKtunes up well with the tuner (with the right switches in the proper place on the tuner) and it seems OK. So, how tough is this tuner in the K3?

Re: [Elecraft] Thinking of selling my K2 wondering about value?
It is worth more than you will get for it in cash terms. When you sell it you may miss it and may have to build or buy another one. I am keeping mine! However, I believe $600 is the going rate for the basic K3, at least it is over here in Europe. Yours has many options so could easily be worth perhaps $1200. I work on the simple principle that new, second hand gear is worth at most around 2/3 of the current new price. But, K2s and K3s can exceed this. As it is the 100W model you might get more if you sell the KPA100 and KAT100 separately. The 10W K3 with the transverter interface is a popular driver for VHF and up and also is still a popular QRP radio, you would probably get nearly $800 for it and maybe $500-600 for the PA/ATU. I am not sure why you think the K2/100 is not a good mobile rig. It has everything necessary except a remote head unit. If it will not fit you might be better off getting a different vehicle, or sticking with the 706.

[Elecraft] K3 audio distortion
Dear fellow Elecrafters, I think this topic has fallen into oblivion somehow. Have been using my MD-7506 for many years now with absolute satisfaction either for ham purposes or music. Not so in combination with K3! In fact the audio sounds terrible. I tried a cheap PC headphones with 32ohm (MDR-7506 have 64ohm) and they indeed sound much better. Could this be because of lower impedance, limited frequency response or both? Is there a solution for the poor guys with too good headphones? Jan OM2XW K3 #1382 Is anyone else experiencing distortion when using the monitor facility onSSB ?I experience quite severe distortion when using my Sony MD-7506 headphones,slight distortion with my Heil Pro Set and none with my Yaesu YH-77ST. Inother words the wider the frequency response of the headphones, the worsethe distortion. In fact it appears the distortion is a high frequencycomponent as I can clean it up completely with audio filtering after theheadphone or speaker output but it should not be there in the first place.It is there with several different microphones but it does not appear on thetransmitted signal which is clean.It is not my Sony headphones which are at fault as using them the audiothrough my TS2000 monitor is absolutely clean.73 Barry Simpson VK2BJ K3 #1397 _ Discover the new Windows Vista http://search.msn.com/results.aspx?q=windows+vistamkt=en-USform=QBRE___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Microphone ground
Good question .. others will answer it but I just had to comment thus... I have had serious rf pickup problems with all of my radios and several different kinds of microphones. The root problem is that I have ladderline coming right into the shack but I can't change that. Microphone cable shields ought to protect the front end of the audio chain in the radio but very often the microphone cable shield is *not* directly grounded to the chassis of the radio. There is a suggestion on the Heil website that one can often solve rf pickup problems in the microphone by making sure that the microphone cable shield is *directly* connected to the metal microphone connector. Heil makes the point that often the mic manufacturer connects the cable shield to one of the pins on the mic connector but leaves it to the radio manufacturer to connect that pin to the chassis of the radio. The radio manufacturer designer does connect this pin to the chassis but that involves an extra inch or two (or more) of wire in the ground circuit and, especially at higher frequencies, that can be enough to allow rf on the outside of the mic cable shield to couple to the wiring inside the shield. I had that problem in spades on 10M and 6M with my K3. I fixed it by connecting the mic shield within the mic connector directly to the metal connector shell which, of course, screws onto the mic connector on the radio which is bonded to the chassis. This improvement was suggested by Heil on their website. What kind of mic am I using? An Elecraft MH2 .. which, I think, is made by Heil. Go figure. I'll bet I am not the only one with rf-in-the-mic-circuit problems. So, I thought I should pass along my experience. Don K7FJ Does the Elecraft require a microphone ground as well as the usual ground for its microphone connector? If so, should it go to to pin 7 or 8 on the Elecraft mike connector?

RE: [Elecraft] K3- How Robust iis the Tuner?
I would think any danger would be to the external tuner or the coaxial link between the K3 and external tuner. The built in tuner (or any tuner) simply tries to find a match - compensate for any reactance and transform the remaining resistive impedance to 50 ohms. It doesn't matter why there's a mismatch. If it can find a match it's fine. Obviously, the KAT3 is rated to handle any impedance it can match at up to 100 watts, with a decent safety margin beyond that. If the impedance presented to the rear panel is too far off, it should not be able to find a match and you'll see that on the display, but that wasn't the case in your situation. What possibly happened, assuming you have coaxial line connected to the K3, is you melted the coax center insulator. That takes a lot of current or voltage, but a really high SWR can exceed the coax's ratings at significant power. Remember, the match you see on the K3 display only says that there's a 50 ohm non-reactive load on the final amplifier in the K3. It says nothing at all about the impedance (and so SWR) present at the antenna connector on the back of the K3. Usually what happens if you overheat the coax is that it shorts as the center conductor insulation melts and the center conductor touches the shield. If it didn't get hot enough long enough for that to happen, you'll not know about it and everything will be fine unless you check your SWR on the line. An easy way to do that is to check the SWR at your external tuner, adjust it to 1:1 and then see if the K3 agrees it's 1:1 with the KAT3 in bypass. If the coax was damaged enough to move the center conductor significantly, it will no longer be a 50-ohm cable. But it would take pretty extreme damage to show up that way unless you have a very long piece of coax running between the K3 and your external tuner.

Re: [Elecraft] K3_ CW Sideband_ Sidetone
Ken, The K2 uses high-side LO injection for the bands 17m and below, but for 15m and above low-side LO injection is used. What that means is that the K2 'switches sidebands' at 15 meters and above. That is the reason that the recommended filter/BFO setup is done on one of the lower bands (40 meters is usually recommended), and the CW filters are set below the filter center and the CWrev filters are set higher than the filter center. The same goes for SSB - LSB is below the filter center while USB is above *except* for the 15, 12 and 10 meter bands where the sidebands are reversed. The firmware automatically corrects for the shift, but you can see it in a waterfall display. If you are using the RTTY filters, they are usually set with the sidebands like those for CW and SSB, but the normal mode of operation is with RTTYrev which will be the upper sideband set. 73, Don W3FPR Ken Roberson wrote: Hello All, My first time to ask fer help.

Re: [Elecraft] K3- How Robust iis the Tuner?
Maybe it needs to be more robust? Last week I was attempting to tune a short ladderline fed (via a balun) doublet on 80 meters using the KAT3. The tuner successfully tuned the system for the cw part of the band, but had trouble on 75 meters. I tried retuning a few times, and noted smoke and a burning smell. Now antennas connected to the ANT1 connector are deaf, while using the ANT2 connector the tuner works fine. I've successfully used this antenna on 80 meters using an external manual Palstar balanced tuner, but never got a match using the internal tuner in my IC756. While the IC756 tuner cannot provide a match, it never was damaged in my attempts. On the bright side, Elecraft support is sending a replacement KAT3, no questions asked.

Re: [Elecraft] K3- How Robust iis the Tuner?
Just for information, DX Engineering has a good page on their website (Choosing the correct balun). They recommend current type baluns, but different ratios for different antenna. I use a multi band dipole fed with ladder line. I use what they recommend for a multi band dipole. The antenna is cut for the lowest frequency to operate, and use a 1.1 Balun. The ladderline is 1/8 multiples of the lowest frequency to operate. I use the 450 ohm ladder line because it was on hand, 300 ohm is what's recommended. With this setup my Palstar tuner tunes easily, and the K3's tuner tunes easily as well when used alone with the antenna. I hope this of interest to the group.

Re: [Elecraft] Thinking of selling my K2 wondering about value?

When you sell it you may miss it and may have to build or buy another one. I am keeping mine! However, I believe $600 is the going rate for the basic K2, at least it is over here in Europe. Yours has many options so could easily be worth perhaps $1200. I work on the simple principle that new, second hand gear is worth at most around 2/3 of the current new price. But, K2s and K3s can exceed this. As it is the 100W model you might get more if you sell the KPA100 and KAT100 separately. The 10W K3 with the transverter interface is a popular driver for VHF and up and also is still a popular QRP radio, you would probably get nearly $800 for it and maybe $500-600 for the PA/ATU.

Re: [Elecraft] Microphone ground
Lew, The mic cable shield should be connected to the shield of the mic plug, and in turn the mic jack shell should be connected directly to the enclosure by a very short path. Unfortunately, that does not happen in most ham gear constructed on PC Boards - it is easy to connect the shell to the board ground, but that is the wrong place, it really should connect directly to the metal enclosure for best RF prevention. See Jim Brown's (K9YC) frequent posts referencing 'the pin 1 problem'. The shield should not be used for any of the signal returns. Normally the PTT return connects to pin 7 and the AF return connects to pin 8. lew wrote: Does the Elecraft require a microphone ground as well as the usual ground for its microphone connector?

RE: [Elecraft] [K3] FLx GN Adding Db gain
There is a table of first guess filter gain settings that Elecraft uses for factory-built units in the K3 Utility Help on the Crystal Filter configuration page. The 400 Hz 8-pole filter has 7 dB of gain in that table. After starting with these approximate values, you might measure the AF voltage at the speaker, perhaps with the alternate VFO B display function AFV described on page 36 of the owner's manual to display the AF voltage and set the filter gain settings so that the AF voltage stays relatively constant as you change bandwidth when tuned to a steady carrier (perhaps generated by a signal generator). You could also clip a voltmeter across the speaker leads. Some just do this aurally.

RE: [Elecraft] Microphone ground
Lew, The Elecraft documentation shows the mic ground connected to pin 7, the PTT ground connected to pin 8 and both pins connected to chassis ground through a common RF choke. In some stations, the common RF choke results in common mode RF (also known as a Pin 1 problem) feedback. The proper connection would be: mic return to pin 7, PTT ground (chassis) to the SHELL of the Foster plug and the SHIELD of the mic cable to the SHELL of the Foster plug. The mic cable SHIELD should NOT be connected to the MIC element (it should connect to the CASE or float). 73, ...

[Elecraft] [K3] VFO A tracks VFO b, Help
I updated my firmware and caused a problem. I have not purchased a sub receiver and is not installed. When I'm in VFO A, and do a band change, VFO B follows the same band. I can swap A=B or B=A, move from A to B or B to A. But I can't have VFO A on 40 meters and VFO B on 20 meters. The Band switch transfers both VFO's to the same band at the same time. What have I done? Tnx Ted WA6RIV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K3 audio distortion
I have the same experience with the Heil Proset ic. Adjustments to TX audio of 2.4K and 3.2K seem to have the most impact. Jim - W6VAR Jan Babinec wrote: Dear fellow Elecrafters, I think this topic has fallen into oblivion somehow. Have been using my MD-7506 for many years now with absolute satisfaction either for ham purposes or music. Not so in combination with K3! In fact the audio sounds terrible. I tried a cheap PC headphones with 32ohm (MDR-7506 have 64ohm) and they indeed sound much better. Could this be because of lower impedance, limited frequency response or both? Is there a solution for the poor guys with too good headphones? Jan OM2XW K3 #1382 Is anyone else experiencing distortion when using the monitor facility onSSB ?I experience quite severe distortion when using my Sony MD-7506 headphones,slight distortion with my Heil Pro Set and none with my Yaesu YH-77ST. Inother words the wider the frequency response of the headphones, the worsethe distortion. In fact it appears the distortion is a high frequencycomponent as I can clean it up completely with audio filtering after theheadphone or speaker output but it should not be there in the first place.It is there with several different microphones but it does not appear on thetransmitted signal which is clean.It is not my Sony headphones which are at fault as using them the audiothrough my TS2000 monitor is absolutely clean.73 Barry Simpson VK2BJ K3 #1397 _ Discover the new Windows Vista http://search.msn.com/results.aspx?q=windows+vistamkt=en-USform=QBRE ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] NB - DSP/IF
I've had my K3 for about a month now and the NR seems to work very well. However, I have had little luck with either the DSP or IF NB when I hear what sounds like electrical noise. There does not appear to be significant differences between any of the settings and I don't detect an appreciable differrence in audio (which I would at higher levels of DSP). Thoughts?
