Re: [Elecraft] K3 Filter response
The anomaly is not really an anomaly, it is just the other side of the down conversion oscillator. For a filter to pass an SSB audio signal the passband needs to go down to 300Hz or so. For this to happen the attenuation for 0Hz and image frequencies can't be that far down. That is all it is though it is probably better with the 8 pole filter. It can also be eliminated by raising the centre frequency, at the expense of bass response. Unfortunately I don't think you can do this on transmit, though perhaps you could adjust your filter offset. That would not work with the USB/LSB inversion below/above 8MHz. Currently the filter is centred on 1.5kHz by default. The best place for it but if you narrow it down with DSP it is probably better to raise this to 1.8kHz. I am not sure how the filter shift relates to the DSP filter and the crystal filter, i.e. which is adjusted, probably both. However, I find I always need to reduce the filter centre frequency to maintain intelligibility as I narrow the DSP bandwidth. So to make sense of a signal within 1.8kHz I need a 1kHz centre frequency. That is not what I would expect which makes me wonder what the shift control actually does.

Re: [Elecraft] K3 Filter response
Mike, Thank you for the explanation; i understand now that this false anomaly is present with the 2k7 and 2k8 filters. May i abuse of your knowledge to explain to me the following behavior : During receive, the 2k7 and 2k8 filter seem to give a ~ 300 Hz at -10dB frequency; it's ok for my use; during transmit, the same filters seems to give a ~ 500 Hz at - 10dB relative to the 1 kHz attenuation; i've tried to shift the bandpass, but naturally, the high frequency is shifted too. As i work essentially with digimodes, i can accommodate with that; but what is the cause of this difference ? (coupling capacitor, etc). I've tried to play with EQUALIZER, but the ALC bars begin to get non desired values... 73 QRO fr Rudolf, HB9ARI AD6XY wrote: The anomaly is not really an anomaly, it is just the other side of the down conversion oscillator.

[Elecraft] Glitches in K3 Filter response
As I understand it, the K3 switches to a different input bandpass filter at 10.000 MHz which I believe is the source of the artifact. You will get a cleaner response with K3 Filter if the test signal is not at 10 MHz. That's unfortunate, as it's easy to find a clean strong 10 MHz reference from test gear. Perhaps Mike should add a reminder in the help file, when he completes the higher priority items.

If I go to AM mode and press coarse to set the step to 1kHz, this gets changed to 100. This may be intentional; at this big tuning step, 100 steps per revolution is OK. But if I go back to SSB and 10Hz tuning step, the CTS is still at 100. I believe this has been around for a while since I have many times inexplicably found my CTS being set to 100.

Re: [Elecraft] K3 feature request - I want Ducking!
You know Ron, it is actually ironic. I too have been reducing AF gain on my rigs for years but I find I do it more now than I used to and I think I know why. A few years ago I all but abandoned the keyer in favor of the straight key and bug. I'm back to manually generating CW and this manual generation of CW requires more of my brain. I need to hear my sidetone more than I used to. I need to clearly hear so I know when to end a dot or how long the dashes are supposed to be or when to do the next dot or dash. Some day when I'm no longer a beginner on the bug, I may not be so dependent on the sidetone, but for now I need to hear it clearly above the RX output or I'll mess up my sending. So ironically my desire for automation in the form of ducking is driven by my return to manual CW. - Keith N1AS - - SKCC 344c - -Original Message- Subject: Re: [Elecraft] K3 feature request - I want Ducking!

Re: [Elecraft] K3 feature request - I want Ducking!
-Original Message- Isn't this just a matter of setting the monitor sidetone as loud as the AF audio from the signals you are listening to? The MON control is on the front panel, just for that reason. 73, Guy. -- I have MON set to match the AF RX level. That way, when I hit the spot button I hear the sidetone and RX signal at the same levels and can easily tune the signal in. MON = RX level works great during receive. During transmit, I want MON to be louder than the RX AF level. Either MON has to come up or AF has to go down. Turning MON up for TX and back down for RX would be more of a pain that just spinning the AF knob. If I do set MON to be louder than the RX AF level, then the sidetone monitor is too loud for comfort. The bottom line is that I want two different mixes of MON plus AF level, one for RX and one for TX.

Re: [Elecraft] K3 feature request - I want Ducking!
I have to vote with Brian for contest operation. I have a couple threads going on this off the reflector. One thing that may be causing some of the problem re hearing the MON on CW, is that MON does not go up and down with the AF volumn control. I believe some of the hearability issues may vanish if the MON setting established a *RATIO* with the AF control, rather than a constant level into the speaker. This would make the ratio of MON to RX audio independent of the RX gain control of the moment. As it is MON will likely be set below a quiet room irritation level (it does not combine with the received audio when set) which will be a lower level than probably needed because it is heard by itself. Then when time-blended with QSK receive it seems weaker. Should point out to K3 users that (at least with 2.78) if you enable MON and then hit the key, the MON control will be operative while transmitting and one can set the level to match the audio, at least as long as you leave the AF at the same setting. 73, Guy. - Original Message - From: Brian Alsop als...@nc.rr.com To: elecraft@mailman.qth.net Sent: Wednesday, January 21, 2009 8:54 AM Subject: Re: [Elecraft] K3 feature request - I want Ducking!

Re: [Elecraft] K3 feature request - I want Ducking!
I've always advocated having sidetone and SPOT levels be independently adjustable - I sidestep the issue by using CWT rather than SPOT to zero beat a received signal (either auto or manual mode). I then keep MON set for my preferred sidetone level (relatively high, I also use a bug).

Re: [Elecraft] K3 feature request - I want Ducking!
I think the crux of this problem is one of learning to use QSK. That means being able to send without being disturbed by the other noises and distractions. Practice is the solution. It might take a couple days or a couple months. The reward is worth the effort. This remark isn't meant to dis anybody. What blows my mind is the organist who leads the choir, turns pages, plays the organ, uses foot peddles and sings, seemingly all simultaneously. Clearly he/she wasn't born with such a skill..

Re: [Elecraft] HRD cw copy
HRD does not decode Morse code. However, its sister product DM780 (Digital Master 780) does decode Morse code. HRD is bundled with DM780 so you get it with the download. When you select the CW mode, the CW tones are decoded in the receive window. There are some controls at the top of the receive window to help DM780 better decode Morse code. I've run a side by side test of DM780 and CWGet and I have to tell you, CWGet does a much better job of decoding Morse code. I find DM780 best decodes machine generated code and forget about a straight key, but it does better with bug and keyer generated Morse code. The closer you get to perfectly sent Morse code the better DM780 does in decoding it. CWGet does a much better job decoding Morse code, even from a straight key and it has a better tuning indicator, too. The software to properly decode CW cannot be trivial. Don't get me wrong, I think HRD/DM780 is the best one stop solution for logging, rig control, digital work on the market today, and the price is right, FREE, but the Morse code decoding needs some work.

Re: [Elecraft] K3 feature request - I want Ducking!
Kevin wrote: It seems to me with all the feature requests people are looking for a custom radio and wanting the rig to do everything for them. The QSK on the Elecraft rigs is very good the way it is. If you don't want to hear the band between characters why are you working QSK? 1) The QSK *is* very good, but it is not perfect. There is some clicking when the band is noisy or crowded, and it's most likely caused by relatively complicated timing issues. A slight reduction in audio gain while transmitting -- which I now perform by turning the knob -- eliminates this. In non-casual operation -- contests, pileups, etc., it would be very convenient to have this take place automatically. It would go a long way in reducing operator fatigue in contests. 2) Some operators would like to use QSK but are distracted by background noise, even if the QSK is perfect. This feature would provide another option -- someone called it 'soft QSK' -- between full and semi QSK. It would be smoother than full QSK but still allow the operator to be aware of what's going on in the background and be interrupted if necessary. In order to accommodate these different preferences, the amount of gain reduction would have to be adjustable (but not in steps of 0.25 dB!). I think this is an excellent suggestion, and if -- as I think -- it wouldn't be very hard to implement, it would provide a lot of bang for the buck (that is, Wayne's time). -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] CW ZERO-BEATING WITHOUT BUTTON PUSHES
As a adjunct to the recent posts on using the Spot and CWT features . . . There is a third capability that many long-time CW operators intuitively possess. It is the immediate recognition of the correspondence of an incoming signal's pitch to that of the operator's longtime /preferred /sidetone pitch. Just as well known voices of loved ones and friends are instantly recognizable when their faces can't be seen, so also one's preferred sidetone pitch is likewise instantly recognizable when a signal is being tuned in and hits that pitch. This feature of the human brain requires no button pushes other than the initial setting of the sidetone pitch frequency. Once this is set, neither the SPOT nor CWT buttons need be used (on any rig). This cerebral feature is always there, regardless of the brand or model of rig being operated.

[Elecraft] K-2 Part II test and alignment problem
Hi All, I am at the Alignment and Test Part II. Minor problems with direct freq entry were resolved by resoldering connections, but having difficulty described below. PLL Reference Osc Range Test yields 12.099 - 12.086 = 13 Khz range. But the VCO Test yields 5.535 Mhz instead of the expected 10 to 12 Mhz reading. The K-2 receives every 5 Khz . The problem seems to me to involve the 12 Bit DAC (U5). Have resoldered the pins to it.Pin 8 is 5v, but pin 7 stays at 3.4v at all times. Pin 1 on U6 stays at 7.6v. (the 8v Regulator output is 7.6v) The 7.6v output is present to the PLL ref. osc circuit. Turning the dial has no effect on the output of the DAC. The PLL Reference osc stays at 12.099 Mhz. BFO appears to be working fine. Sensitivity appears good as I can easily hear a 1 uv signal. I have thought of putting say, a 5 K resistor across the output of pin 1 (or from the 2.7K R19 to ground) on U6 to change the 7.6v to something lower to see if that changes anything, but not have not tried that yet. I'm trying to think of a way to test the 12 Bit DAC to see if it is good. Any suggestions or help will be greatly appreciated.

[Elecraft] K3 audio problem
Hello, Last night I was transmitting on 160m and using stereo headphones listening with diversity RX and heard some unusual clicking coming from the K3 when transmitting. I pulled the diversity RX antenna that was plugged into the 2nd RX antenna port with no change. I pulled the RX antenna that was plugged into the main RX ANT IN port on the KXV3 and the clicking stopped. This told me I had too much RF coming in on my beverage antenna when transmitting. So I put the 2nd RX antenna back on but now there was no audio output from the KRX3 sub receiver. I'm using the sub audio knob as the balance control between the main and sub receivers. When the sub receiver is on and the pot is counterclockwise I get audio from the main RX in the left ear. But when clockwise there is no output from either side. I did have stereo speakers plugged into the external speaker port in the rear of the K3 and the spkrs were set to 2 when the problem started. Also I haven't done the AF mod yet. W hen I turn off the sub receiver, I get audio out of both sides. Does anyone have an idea of what might have happened? I did fix the high RF level coming from the beverage antenna by putting back to back diodes from the center pin of the coax to ground. Now I can transmit with no clicking coming from the K3.

[Elecraft] AGC Setting for PSK-31
I have a K3/10 (with a 66' dipole in the attic) and get great reception on PSK-31. I have two questions. Should AGC be on or off? Aside from having a dedicated sound card...is there a Rx or Tx advantage to using an interface like Rigblaster.

The K3 is an excellent receiver so don't cripple the receive chain with a poor soundcard - get a quality soundcard such as the Rigblaster and you'll know there's nothing better you can do. Talk to Joe W4TV - he's active in these forums and can help as well. Use AGC however you want. The K3's dynamic range is so good that using your 66' dipole you'll probably never suffer from strong signal overload, especially if you're able to switch in a narrow filter if the going gets tough, for example in an RTTY contest when 1KW seems to be the minimum power level allowed :-) Simon Brown, HB9DRV www.ham-radio-deluxe.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K1 smoother tuning
Well, maybe smoother tuning is not the best description. I built my K1 with the 80kHz tuning range option. With time, I found it was a little touchy. Not wishing to go to a narrower tuning range, I sought another answer. The solution was a weighted, K2 knob and two felt washers. Given the limitations of the K1, it's about as good as it gets. BTW, it is not at all bad cosmetically. 73, Neal WA6OCP K1 2639, K3 305 -- View this message in context: http://n2.nabble.com/K1-smoother-tuning-tp2195423p2195423.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] CW ZERO-BEATING WITHOUT BUTTON PUSHES
I agree Kent, I've also used that method on all my previous rigs. My preferred pitch is 700 Hz. The reason I use the CWT function on the K3 is not so much for the visual cw pitch indication, but rather for the rapid auto-spot/tune function. I find the K3 to be very consistent at quickly centering the CW signal, at my preferred sidetone pitch, in the selected passband of the receiver. Once auto-tuned I can quickly decrease the bandwidth to 100 Hz or 50 Hz and presto the signal is smack in the center of that very narrow passband. It's great for SP with a wide passband (1.2 KHz), auto-spot/tune and a quick turn of the width control to 50 Hz bandwidth. The way Elecraft implemented the CWT function is fast, intuitive and repeatable. It's one of my favorite features in CW mode on the K3. Best 73, Frank - W6NEK - Original Message - From: K9ZTV Cc: elecraft@mailman.qth.net Sent: Wednesday, January 21, 2009 9:48 AM Subject: [Elecraft] CW ZERO-BEATING WITHOUT BUTTON PUSHES As a adjunct to the recent posts on using the Spot and CWT features . . . There is a third capability that many long-time CW operators intuitively possess. It is the immediate recognition of the correspondence of an incoming signal's pitch to that of the operator's longtime preferred sidetone pitch. Just as well known voices of loved ones and friends are instantly recognizable when their faces can't be seen, so also one's preferred sidetone pitch is likewise instantly recognizable when a signal is being tuned in and hits that pitch. This feature of the human brain requires no button pushes other than the initial setting of the sidetone pitch frequency. Once this is set, neither the SPOT nor CWT buttons need be used (on any rig). This cerebral feature is always there, regardless of the brand or model of rig being operated. Several of us used this capability on Straight Key Night when operating a friend's FT-2000 with it's myriad of buttons, switches, and multi-layered controls. Once we set the sidetone pitch to our individually preferred frequencies, zero-beating was intuitive. However, hearing impairment is a whole different issue and may well require the CWT visual aid. 73, Kent K9ZTV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Glitches in K3 Filter response
Mike AD6XY wrote: I don't know about this but I find my K3 switches the filter and band at 9MHz. I tried using 9MHz just now to verify this. The mode changed as I moved from 9MHz to just above. I don't understand why but the mode changed from USB just below 9MHz to TX data just above it. Odd. This does not happen when you spin the dial so perhaps a bug in Mikes program. 9 MHz is the transition between two bands (40 M 30 M) on the K3. When you used K3 Filter Tools to cross the 9 MHz boundary the mode will automatically be switched from the last mode used on 40 M to the last one used on 30 M. Thus, your mode automatically changed from SSB to Data. Users should be aware of these transition boundaries between the bands when they are using K3 Filter Tools. I also found another bug. The AGC was turned off and I was supposed to set the centre frequency. The audio was so loud that it was distorted badly and the volume would not decrease with the pot, even the radio power off switch failed to work. I had to cut the signal to regain control. I have not been able to reproduce this problem, but it is not a bug in the program. K3 Filter Tools does not control the AF gain control at all, but it does turn off AGC. I am modifying the program to turn down the AF gain just before it turns off AGC. That will prevent the loud, annoying burst of sound users are experiencing. Thanks for your comments.

Re: [Elecraft] K2 high current on 15 meters
Brett, Check the components in the 15/17 m Low Pass Filter carefully. Examine C218, C219, C220, C221 and C222 for correct values. Then count the number of turns on L23 and L24. Count the number of times the wire passes through the center of the core rather than the turns around the outside. Go ahead and set the CAL CUR to 3.50 amps. If you add the KPA100, you must increase the setting to 3.50, and with the higher gain using the new transistor at Q6 it is often necessary to increase the CAL CUR limit - it does no harm to increase it. 73, Don W3FPR Brett Gazdzinski wrote: I built K2 #6673 last week, and everything works well, except for a high current warning on 15 meters.

Re: [Elecraft] AGC Setting for PSK-31
The K3 is an excellent receiver so don't cripple the receive chain with a poor soundcard - get a quality soundcard such as the Rigblaster and you'll know there's nothing better you can do. Unfortunately the RigBlaster series of interfaces are not soundcards nor do they - as far as I know - provide any receive interface. They are essentially a transmit interface that provides isolation and switching for the mic line. If you are getting started, connect the line output from your computer sound card to the Line In on the K3 and connect the Line Out of the K3 to the Line in on your computer soundcard and have fun learning all about PSK31. If you don't want the Windows sounds getting from your computer to the radio, consider one of the interfaces with a dedicated USB soundcard, radio control (CAT interface) and other features in one box. Such devices are made by several companies - I'm partial to the microHAM products (www.microHAM-USA.com) but then I distribute them in North and South America. 73, ...

I have two questions. Should AGC be on or off? Aside from having a dedicated sound card...is there a Rx or Tx advantage to using an interface like Rigblaster. Thanks again for all the help you have provided! The K3 is an excellent receiver so don't cripple the receive chain with a poor soundcard - get a quality soundcard such as the Rigblaster and you'll know there's nothing better you can do. Talk to Joe W4TV - he's active in these forums and can help as well. Use AGC however you want. The K3's dynamic range is so good that using your 66' dipole you'll probably never suffer from strong signal overload, especially if you're able to switch in a narrow filter if the going gets tough, for example in an RTTY contest when 1KW seems to be the minimum power level allowed :-) Simon Brown, HB9DRV www.ham-radio-deluxe.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
