[Elecraft] K3 and MixW PSK31
Thanks for the replies and settings etc. All to no avail sadly. The K3 will work on CW but stubbornly refuses to TX on DATA A either RTTY or PSK31. This was a factory built unit and if I was located near Aptos it would be on it's way back to be checked out fully, sadly I live a little ways beyond California. Oh well, who wants to play with a computer when you can find a human to converse with...so no more data stuff for me, life is way too short to waste time playing with 4 data programs that simply don't work with this particular K3.

[Elecraft] K3 Beta firmware rev. 2.72: updated DVR support, etc.
K3 beta-test firmware revision 2.72 (with DSP rev 1.98) is now available. Anyone who has the KDVR3 (Digital Voice Recorder) installed will need this revision to use the DVR. We'll be making further improvements to DVR functions in later releases. Full details appear below. Please send any problem reports to [EMAIL PROTECTED] For instructions on how to load beta firmware, please see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 2.72 / DSP 1.98, 12-9-2008 Misc. Changes: * LINE OUT INCLUDES TX AUDIO: LINE OUT (nor menu setting) now includes transmit sidetone and speech/data monitor audio. * IMPROVED TX PASSBAND FLATNESS FOR PSK31: When operating in PSK31 mode via a PC, high-pitched audio tones are no longer attenuated more than low tones. Support for Digital Voice Recorder option (KDVR3): Note: The following information is more accurate than the DVR instructions in the K3 rev D owner’s manual. * DVR ICON: The DVR icon (dual arrows--above the S-meter) turns on whenever the DVR is in use. The icon flashes slowly during all record operations, and quickly during play. * DVR TX MESSAGES: Message record, play and repeat are functional. (Message chaining will be added in a subsequent release.) To start voice message record, tap REC, then tap M1-M4. Record will start immediately. Tap M1-M4 again to stop recording. To play a voice message, tap M1-M4. To repeat a voice message (e.g., a CQ), *hold* M1-M4 rather than tap. Message play or repeat can be cancelled at any time by tapping REC. * DVR RX LOOP: Hold AF REC to start receive-audio recording. Hold AF REC again to stop record. Up to 90 seconds of audio can be recorded; beyond this, earlier audio will be overwritten. Hold AF PLAY to start playback; press any switch to stop. VFO B will show the playback position in seconds, relative to the most-recently recorded audio segment. During PLAY, you can move forward/backward through RX audio loop buffer by rotating VFO B. An asterisk (*) beside the seconds counter shows the extent of the most recently recorded segment. Note: It is OK to record received audio continuously; this might be useful as a way of catching audio events that you wish to examine later. Record will continue even if you transmit. However, at present, silence is recorded for the duration of any transmission. * DVR RX LOOP PLAY IN TX MODE. First, enter voice transmit mode by holding PTT or tapping XMIT. Then hold AF PLAY to start playback, and press any switch to stop. CMP (speech compression) is automatically disabled. Note: Playback volume of the RX loop buffer during TX mode is not yet adjustable. For software developers: * VOX STATUS ADDED TO IC CMD (separate flags for CW keying ‘VOX’ and voice/data audio VOX). --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Audio Problem
My DSP board failed 4 months after the kit K3 #818 was assembled. I had no audio anywhere. The S meter showed almost full scale. The receiver resting current went from .85 to 1.01 amps. Replacement KIO3 boards did not cure the problem. Gary at Elecraft suggested it might be the DSP board if the KIO3 boards did not solve the problem. I sent the rig to Elecraft for warranty work and it was the DSP board. Great service from Elecraft and Gary by the way. Since the QST review of the K3/100 also had an audio failure along with a few reported on the reflector, I wonder if there is a design/reliability problem here?

For those in the UK and probably the EU, their supply of the AF mod is a great benefit and a lot cheaper, given the US exchange rate and shipping costs. I would have brought mine from there had I known about it sooner and been able to cancel my order at Aptos (which shipped just before they got my mail). Chris (the owner) is up to his eyes in orders (not just K3 mod kits) and is unable to reply to previous comments about his site due to pressure of work.

For a short period the wrong instructions sent with the current type of fans.

If not, I have found link-coupled designs in Bill Orr's 1967 Radio Handbook and the 1949 ARRL Radio Amateur's Handbook (cover price $2.00!) that should be easy to scale to six meters.

[Elecraft] K3 Diversity Rx and antennas
I'm just waiting for the lovely lady at Elecraft to send me the gram for the sub-rx. In the mean time I'm contemplating the 2nd wire antenna to hoist up for diversity Rx. My QTH is surrounded by dense trees, cedar 120+ ft tall. Think planet Endor, ewoks, and pesky storm troopers around every corner. Now for the 2nd wire antenna, I was envisioning a Beverage because I can run 1000' wire over 7acres in a loop within 30' off the ground without getting snagged by the branches. Over 30' then I run into problems with very dense branches acting as barbs in the wrong direction preventing wire from going up. My main Tx antenna is a wire dipole at 25m cut and somewhat even on each side for 80-20m work. I'm tempted to take it down and make a new one for 160m + 80m-20m work. Anyway, the question is: for Diversity Rx, would a 15-25' off the ground Beverage be suitable? Or, does diversity work best if the polarization is opposite, -- among the variables involved with wire antennas, what variable to I look for to increase the benefit of having diversity Rx? Reply directly and I'll consolidate the responses here on the list. -jeff -- Jeff Wandling DE W7BRS K3 #2105 http://w7brs.com/k3 [EMAIL PROTECTED] ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 Large tuning knob for VFO B
I have installed a standard main tuning knob on VFO B for the second receiver on my K3. The grand purpose of this is to get an equal feel for VFO A and B for tuning the second receiver. It works well for this purpose. The front panel symmetry does not look as nice to me as with the original small knob. It covers the Text Dec and B lettering but does not interfere with any controls. It hangs about 1/4 inch below the panel but clears the table by 1/4 inch with the tilt bail closed. I think I will get used to the appearance. I like the K3 knobs and do not feel the need for a Yaesu or other knob. Aloha, John KH7T ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft]Re:M0DXF, Dodgy Site
David, M0DXF, your post under the above heading is rather confusing, padded as it is with quotes, quips and comment to yourself. Furthermore, Chris is bewildered by what you sent to him, as he's asked me what the heck is going on. Bear in mind he's not like some on here, glued to the Elecraft reflector. It's something that's quite new to him and as a busy guy with no Elecraft gear himsef (shame), the posts on here hold no interest for him. On that basis, I suggest that if you wish to communicate with him, put it in a plain email rather than an extract of the reflector, which starts with "Hello Suspicious". IMO, that's just not on! I gather, from your post on here and G4AON's direct email to me, the problem is with a LINK FROM the site and not the site itself. Thus, I think it's fair to say that the site, which is successfully accessed by his customer base, holds no risk in itself. I strongly suggest that this topic should not be aired here on the reflector and if you wish to discuss matters, email either me or Chris with text he can understand. When he emailed me about the message he'd received, he mentioned that he'd already had some sales of the mod kits, posted out today. 73 Dave L G3TJP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Noisy fans?
Thanks Tom (and several others too!), I'll contact Elecraft. Screws tight, but not over-tightened. Finger guards centered. Fans move air in the right direction. Also, nothing touching the blades. I did notice that the instructions said to install some bushings at the corners of the fans. My fans were made so that "bushings" were already part of the fan and bushings were not in the kitcould be a change in supplier or fan model. Also, the instructions (including errata) didn't apply to my fan model. Interesting...and it's got to be a tough job for anyone to keep up with suppliers and all the details that go into producing these kits! My k3's serial is 1719. I just checked the fans again using the TECH-MD PA-FN1 thru PA-FN4, and yes, they do "whine" at all speeds, although sounding different of course with varying degrees of "whine". Listening very carefully when they power-down, I could swear that the fan bearings and/or brushes (if there are any) sound rough.

After installing the latest firmware, I installed the KRX3 that I just received yesterday. All went smoothly until I went to Calibrate KsYN3 (p 43 in KRX3 Manual). I keep getting ERR 00227 VCO. I also received the ERR 00228 VCO one time. Before calling Elecraft, you could try pulling the synthesizer, check that nothing could be shorting to the shield and then reinstalling it. After I installed my KRX3, my original synthesizer was giving me similar error codes. In an act of wild desperation, I pulled it and plugged it back in, adding two washers (one left and one right, if I remember correctly) so that it was tad further away from the shielding. Since then I have not had any more problems. I assume that it was moved a tiny bit closer to the shielding while I installed the KRX3, bringing it close enough to make contact. The two washers I added were in the installation manual for the KRX3's VFO but not in my (early) construction manual for the basic K3 (#67).

Re: [Elecraft] K3 Noisy fans?
I find that at an ambient temp. of about 17C, 75 W into a dummy load, it takes about a minute and a half of CW at 18 WPM to raise the PA temp from 23C to 37C, the temp at which the fans come on at the slowest speed. 73 -- Joe KB8AP On Dec 9, 2008, at 10:55 AM, Richard Ferch wrote: The fan noise depends on the fan setting, which in turn depends not only on the duty cycle but also on the ambient temperature.

Re: [Elecraft] K3 Noisy fans?
I have certainly been surprised by folks who say they cannot hear their fans. I can (although they rarely come on) and I even had Gary send some replacement units, but when I changed them over the improvement was not great. I've checked all likely reasons, it's not the sound of a fan touching something. I wonder how genuinely quiet some people's shacks are. If I had a Windows desktop PC on the desk alongside I'm certain I'd never hear them, similarly if I had an amp running, or any other of the constant sounds you just get used to until hit by the sudden quiet of a power cut! To put things in perspective, the K3 fans are excellent compared with the IC706 or IC7000 for example, where their noisy fans even cut in on receive! So, it's all relative I suppose. These days I almost always use open headphones (Sennheiser HD590) so it's not really an issue- I can just detect the fans turning on whilst wearing them. On a different note, closed headphones (unless I'm on a plane) I find claustrophobic, as if I have cut myself off from the rest of the world! 73 Stephen G4SJP K3 #980 K2, KX-1 On 09/12/2008 18:27, "W7TEA" <[EMAIL PROTECTED]> wrote: > > > When I received my factory built K3 last spring (#1001) I thought > the fans were louder than I expected after reading about folks > who had to physically check to see if there fans were on.

Re: [Elecraft] FLx GN at Maximum
Following the procedure below I ended up with the gain for my 400 Hz roofing filter set at the maximum 8 dB setting. There are nominal variations in the various filters. My 400 Hz filters happen to need a gain of 4 (sub) or 5 (main) dB. My 250 Hz filter (main) needs 7 while my 200 Hz filter (sub) needs 3 dB. The limit of 8 dB is software enforced. The DSP can apply significantly more compensation if necessary. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Noisy fans?
When I received my factory built K3 last spring (#1001) I thought the fans were louder than I expected after reading about folks who had to physically check to see if there fans were on. I could hear the fans start up through my headphones when PA temp hit 37C. I sent the rig back and the good folks traded out a few other fan modules and reported that the noise level was the same and appropriate. I inquired about Elecraft changing fan suppliers. They said that had happened, but the new supplier's fans were as quiet. So, I believe there are a variety of experiences. My fans are not whisper quiet, but maybe I, too, have been spoiled by my TT rigs with external cooling fins and no fans. Gary W7TEA I was trying to ferret out some weak signals on 160m when the cooling fans switched on, making it very hard to hear over the "whine" of the fans (or fan) even through the padding on my headphones.

[Elecraft] FLx GN at Maximum
Is it unusual or does it cause any problem to have a filter gain setting at it's max value? Is that gain occurring in the IF DSP or elsewhere? Following the procedure below I ended up with the gain for my 400 Hz roofing filter set at the maximum 8 dB setting. I used the Elecraft XG1 (set at 50 microvolts output level) direct into the K3 (sn 1774) which was in CW mode and set initially to the 7040 kHz nominal frequency of the XG1. I then used the CWT and SPOT controls to tune more accurately, showing the oscillator to be about a 0.1 kHz low. At the stock 2.7 kHz roofing filter width the AFV indicated 1248. With the 1.8 kHz roofer it showed 1275 and initially the 400 Hz filter showed around 1130(?) with the FL3 GN set at 2 dB per the "typical" mentioned in the manual. But using the AFV indicator, I ended up increasing the FL3 GN to 8 dB, it's maximum setting. This brought the AFV indication for the 400 Hz filter up to 1250. Switching between the filters and just listening, the signal levels do sound exactly the same. In the analog world, I'm sometimes concerned about "calibration" controls set at their extremes but maybe it is an non-issue here?

Re: [Elecraft] Dodgy site
I think the problem is that Mode Components is using a free web host that has some dodgy users. There is probably nothing wrong with the site itself, but Kaspersky regards Free Web Town as a bad neighbourhood, with some justification if Google is anything to go by. Given that web hosting is available for well under a tenner in the UK from reputable hosts like 1+1, I don't know why someone would penny-pinch to the extent of using a dodgy free web host for their business site. My hunch is that this site is safe to visit. But it is quite a common problem that malware is planted on legitimate sites by hackers exploiting weak passwords and security vulnerabilities, so even your local church website could end up delivering malware.

Re: [Elecraft] PR6
I've had mine for several weeks. It replaces a Down East Microwave (kit-built) unit and works well. The DEM has -slightly- more measured gain but a bit less bandwidth at the 3db points. Mine measures 14db of gain at 50.4 mHz and the -3db points are at 43.8 and 58.1 mHz. The automatic enabling feature in the software is nice, too. It's a "quiet" pre-amp. I can't comment about on-the-air use, as the band's been dead. Am waiting on my 2nd receiver so I can monitor the band all the time. The PR6 is beautifully built and in a nice machined housing. It comes with all needed cabling and even a pair of male-male BNC connectors in case you want to hang it directly off the back of the K3 ... I don't! The only improvement I would make would be to make the white control lead a bit longer, as it tethers the preamp too close to the radio, placing it in direct competition with other cables behind the radio. 73!

RE: [Elecraft] K3 Noisy fans?
Though my K3 is still in utero and I have no personal experence with the fan noise on it yet, I might suggest getting some foam baffling like you see on some speaker grills and mount that behind the radio and if possible, angle the batting to deflect the fans sound waves above or below, so they do not reflect directly back to the radio and as well, back to you. If you direct the sound lower you might have a bit of this baffling taped to the back of the desk and that will break up the resonance which will only serve to amplify the sound. An ideal material would be the irregular shaped sound proofing AKA acoustic tile as the material tends to not reflect sound but the irregular shapes on its surface break up resonance. Fiberglass would be great except for the obvious problem of the slivers. very wrinkled terrycloth would be better than nothing, if you can't find such batting, be creative; something you have on hand or can find easily will surely be of some help. Just use something fuzzy at the least. The closer the sound is immediately to right angles will increase the lower registers as in the reason floor mounted speakers carry more bass than ones mid level & in the open, up the wall. 73, Gary KA1J ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 compression settings
I believe compression and equalization are both automatically disabled when in a data mode (including DATA A). Tx EQ is currently set for the radio, not the mode. Likewise Rx EQ. Compression is disabled for DATA modes that use audio input (DATA A, AFSK) and restored for USB/LSB operation. Having Rx EQ and Tx EQ be saved by mode is on th elist of things to get done. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Noisy fans?
Charlie, Yes, I have battled the fan noise, too. I got replacement fans which seemed a little quieter, but I still had no doubt when they were running. I noticed that if I removed the fan panel from the rig and held it in my hand while the fans were running, they were very quiet. So I went to the local hardware store and found some neoprene (rubber) washers about 1/16 inch thick. I placed them on the bolts between the fans and the mounting plate. That has helped to quiet them down quite a bit. I still know when they're running, but it's tolerable. I've also found that where I place the K3 on my desk makes a difference in how loud the fans sound. My desk is in a corner of the room and if I place the K3 so the back is pointing into the corner, the walls reflect any sound right back toward me and the fans are louder. If I place it on a table in the middle of the room, I don't notice the noise nearly as much. 73 -- Joe KB8AP On Dec 8, 2008, at 9:31 PM, Missouri Guy wrote: I was trying to ferret out some weak signals on 160m when the cooling fans switched on, making it very hard to hear over the "whine" of the fans (or fan) even through the padding on my headphones.

Hi there, I have a little problem with K3 #549. I do not get AF out of the internal Speaker or rear-panel Speaker output. I am usually using headphones so only noticed it recently in Senegal when I wanted to have my YL listen to a sked with home. It doesn't seem to be a hardware problem because when I set SPKR+PH to yes in the menu I do get output. Only if it is set to no and I don't have headphones connected is there no output. I've tried setting SPKRS to 1 and 2 with no difference. Is there some other setting that I am missing that could be causing this behaviour? I've also tried upgrading to the latest firmware but that didn't make a difference either. I'd be grateful for any ideas. Thanks and regards, Carsten, DL1EFD ___ 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 Noisy fans?
Take the top cover off the radio Charlie and check for nearby connecting wires contacting the fans - when they do you get an alarming buzz but if the degree of contact is very slight I presume it may just sound like a 'normal' noisy fan. The K3 fans are completely noiseless. BTW you don't have to wait for the temp to rise to check the fans 'cos there is a menu entry (Config - KPA3...??) where you can test the 4 speed settings of the fans. I always check this after being inside the radio to make sure I won't get a fright half way through a sessions when the fans come on 73, Stewart Rolfe GW0ETF Missouri Guy, N0TT wrote: > > I was trying to ferret out some weak signals on 160m when > the cooling fans switched on, making it very hard > to hear over the "whine" of the fans (or fan) even through > the padding on my headphones. > > Has anyone tried to quiet them down with vibration > isolators, etc? > > Charlie, N0TT > ___ > Elecraft mailing list > Post to: Elecraft@mailman.qth.net > You must be a subscriber to post to the list. > Subscriber Info (Addr.
