Re: [Elecraft] K3 and QSK
Interesting indeed. First impressing when getting the K3 was: "Where is this flawless QSK people are raving about". More use detected this flawlessnes frequently. I always use QSK (not QRQ version) on the K3. At some times it is absolutely wonderful, at others there are all kinds of thumps and clicks. This is particularly puzzling since I always almost always use the same filter settings (250 Hz filter set to kIick in at 350 Hz, 350 Hz bandwidth selected), same AGC, same audio settings and same earphones. One can clearly see a "thump" on the panadapter when there is a problem. I generally keep the monitor level low. Some observations: 1) clicks and pops more evident with low monitor settings (contrary to others observations). 2) narrower CW filters seem worse. 3) no clear dependence on dead vs crowded band. Perplexing indeed. It's kind of like sloper antennas which great for some but terribly for others. It seems like a detailed parametric study is needed to determine which receiver and band condition parameters are important and which are not.Also what measure does one used to determine performance? Right now all we have are subjective reports. 73 de Brian/K3KO On 12/5/2014 5:23 AM, Graham g3tct wrote: I'm very interested in this topic, having raised this question a long time back.

Re: [Elecraft] K3 and QSK
Nor do I. ATT=ON/PRE=OFF on 160, 80, and 40 unless 40 is unusually quiet. Then I might set ATT=OFF [not common], ATT=OFF/PRE=OFF on 20, ATT=OFF/PRE=ON on 10, and sometimes PRE=ON on 15 [also not common]. I'm about 90% CW, I run QSK no QRQ most of the time, QRQ in contests. Paddle is on the K3, computer keys via WinKey USB. I haven't touched the AGC settings since the firmware that added all of them came out and I never back off the RF GAIN. AGC=F on CW and AFSK, AGC=S on SSB. I'm moderately deaf from noise trauma many years ago, so AF GAIN is at about 12 to 1 o'clock. I use headphones almost exclusively unless I'm just monitoring 14061 for a SOTA activation, my K3 sounds better than any radio I've ever had including the TS-850 which is noted for great audio. I wonder how many of the various receive artifacts that are discussed on the list would be resolvable with very careful adjustment of AGC and other parameters? 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 12/4/2014 11:02 AM, Guy Olinger K2AV wrote: I definitely don't have the CW QRQ problems that others seem to be describing. __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3 and QSK
One of the pieces of advice for operating the K3, is to use the minimum amount of gain in the RF/IF string. This is done by setting ATT/PRE/RF gain so that there is only a moderate amount of band noise with no signal, then setting audio for a comfortable level on signals with AGC engagement. This keeps from having the radio "roar" in your ears all the time, particularly with fast AGC. If ATT/PRE/RF gain are always running wide open, the QSK noise is predominately from starting RX state with this unnecessary gain level. For example listening on my 160 transmit antenna I always run with ATT in line, and RF gain backed off just a little. Also, with the deliberate short transition times for CW QRQ, one must understand that one is modulating the "channel" content with a square wave. From the physics, some degree of click MUST be generated if the "channel" has loud content because the RF/IF string is operating wide open with signal content and modulated with a on-off transition deliberately set by the operator. If a delay is introduced to whack off the click, you have just defeated the desired extremely short transition of CW QRQ. Which one do you want, modulation of channel content with extremely short transition which allows you to hear anything between fast bauds, or a "rounded off" transition that doesn't hear stuff at the transition edge, but doesn't have any "sharp" sounds. Me, I do NOT want the "rounded off" transitions, because I want to hear as much as possible in the interbaud time, and don't care if it makes the stuff sound "harsh". I find the harshness greatly minimized by not running ATT/PRE/RF gain wide open all the time, and using fast AGC with CONFIG: AGC - F = 200. One firmware thing that could help to some degree (if it isn't already done this way) is to start the AGC in the new interbaud space with a value held over from the prior interbaud space. I definitely don't have the CW QRQ problems that others seem to be describing. 73, Guy.

That also depends on the amount of signal and noise in the background. Turning down either the audio or RF gain helps with both artifacts, but makes the output lower than desirable. I talked to Wayne and Lyle a long time ago about possible ways to ameliorate these noises and they had some ideas, but I haven't heard anything recently.

[Elecraft] K3 and QSK
Hi Vic, With interest, I read your emails about the K3 QSK and the noise it produced and I have a question for you. I've had my K3 for about three years and I purchased it with a full complement of CW filters for both receivers, including the 8-pole 250 hz filter. I normally run my radios in full QSK, but of course, depending on sending speed, running the K3 in full QSK means you lose too many other good features. I never really noticed the noise generated while in full QSK until recently, and it is quite bad! About a year ago I changed my 8-pole 250 hz filter to the 5 pole 250 hz filter and actually I think that is when I started noticing how bad the pumping and generated noise from my K3 sounded. Of course I run AGC-Fast, with no preamp (unless on 10m and then only seldom have the preamp turned on). My question to you is do you have the 250 hz filter installed in the main Rx and if so, is it the 8-pole or the 5-pole? I think right after Christmas I am going to re-install my 8-pole filter just to see if that has any bearing on the awful QSK noise. Also, have you had any response from Elecraft on this issue?

Re: [Elecraft] K3 and QSK
That's true. But if you don't have a QSK amp, using PTT to switch the radio from RX to TX, send the memory (CQ, Exchange or QRZ) and immediately back to RX is the next best thing.

Re: [Elecraft] K3 and QSK
Well, the response to this was rather positive for having the ability to turn off QSK. I, like Tree, should have included the point about having PTT input for CW. Since I rarely use an amp or full breakin, I previously didn't have a need for a footswitch in CW. But I now will consider it's use after reading this thread. Thanks!

[Elecraft] K3 and QSK
Radio "Off" brings back memories. A few years back, a good ham friend of ours, with whom we had a daily ragchew on the Baltimore Beltway, told us this story: "Following our sometimes long ragchew on 2 meters, on one of Baltimore's famous repeaters - he drove a little farther north on his 58 mile daily commute toward his home in Pennsylvania (Stewartstown, PA), at the end of his workday. Ah ... the Baltimore County repeater (K3SP) had activity. A younger voice was on, in a QSO. Sounded familiar he thought. He listened for while - but the talking went on and on. He wondered who this ham was? He even heard some familiar names mentioned? ... Turns out his 5 year old, at home, had turned on his 2 meter rig - and was talking on the rig "like Daddy always does"! The only other "rig off" incident, happened to me on a Saturday night - when I took the wife out to dinner. While on our trip south, I was explaining how our local repeater and its gang worked. I even mentioned names and characters, and even told her about a couple of cranky ones. Turns out my 2 meter rig was on, and keyed - throughout that whole personal conversation. I guess all of Baltimore got wind of our converstation that night! Wonder what else I said that night? Fred, de N3CSY Boardwalk for $500? In 2007? Ha!

RE: [Elecraft] K3 and QSK
I too vote for a QSK OFF state to accomplish this -- it seems the most convenient way that I can think of My ICOM 735 uses VOX for this - it becomes "KOX" in CW mode. But I don't like that very well because when I switch to phone the VOX will be on and I dislike VOX. I guess that using VOX would be OK if the setting were mode-dependent, but on the old rig it's an in/out switch. 73, Carl WS7L ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

When placed in the newly added CW OFF Mode, pressing a footswitch connected to the rear PTT input will allow the paddle or key to go into CW Xmit. That's the way it works on 3 other rigs I have in the shack. I guess I just assumed that the K3 would be set up the same way.

RE: [Elecraft] K3 and QSK
I've only done footswitch PTT on phone. Interesting idea to do it on CW. I like the "paddle disable" concept. So if the footswitch controlled a relay that was inserted between the paddles and the rig, then you could use the footswitch to disable and enable the paddles. The actual TR switching would be done by the QSK circuit. I guess if you wanted to swap antennas from RX to TX or do other things, then there would be more functions tied to the footswitch for antenna switching, amp enabling, whatever. Would this all be taken care of by an external box or does it have to be addressed in the rig? - Keith N1AS - - K2 5411.ssb.100 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Yes, you can put the K3 into transmit with PTT, but you cannot PROHIBIT it from going into transmit by NOT asserting PTT. The paddle is always live. Moreover, you cannot stop transmission by releasing PTT if the paddle or KEY input is still making closures. 73, Ed - W0YK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Hitting the paddle puts the rig into transmit. You cannot gate (prohibit) transmit with PTT/footswitch if QSK is still active. Some SO2R control boxes use PTT to enable each transmitter. You may want to insure your amplifier is switched on before RF is applied from the K3. There are lots of other reasons for having this traditional feature.

Why isn't this useful? -- 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] K3 and QSK
This was an issue with the early Orion also. As I understand it, PTT in CW was eventually implemented on the Orion. Some of the contesting software will raise PTT and delay a user specified time before keying to let the T/R switching settle. Also, on all the YaeCOMWood rigs I have used, releasing PTT returns to RX 'instantly' - cancelling any delay set for semi-breakin. Not having a QSK amplifier, and not particularly caring for QSK at all, PTT in CW capability is important to me. I routinely stomp on the foot switch to eliminate the clatter during CW contacts with my ICOM rig - been doing this ever since my DX-35 & way to old to change now. PLEASE make PTT active on CW in the K3! PLEASE 73, Bill N2BC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Currently there is no "OFF" or PTT/footswitch capability in CW. Over on the OMNI VII list a while back (I've since unsubscribed), this was a huge issue, and apparently TT did something in the firmware to make PTT active in the CW mode, something they had never considered during the design phase. The users were saying that in CW contest work, using full QSK is too distracting and tiring, but that any T-R delay at all is too much -- thus the desire for PTT (footswitch) T-R on CW. I'm a casual, not a serious, CW contester, so I have no opinion on the matter -- yet. However, I can understand the point of view.

RE: [Elecraft] K3 and QSK
In many rigs the VOX control will perform the OFF function you're looking for. With VOX off you'll need to push a Transmit button or supply an external PTT signal to activate the transmitter. I haven't read the manual yet but I bet the K3 works the same way. OFF is a very good idea when you're out of the shack. A couple years ago there was a "ditter" who was tracked down and found to be a ham with a misadjusted key that was sending out a steady stream of dits while he was out of the shack unawares. He was duly mortified when the DFers showed up at his front door. Also a good idea if you have cats. -- Carl WS7L ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K3 and QSK
I read the new K3 Quickstart Guide and noticed that with QSK button, I believe that you can only select SEMI or FULL, but no OFF. Why would I want an OFF function? I got in the habit of switching the breakin on my radio to OFF when it is unattended for a couple of reasons. One, I usually have a computer connected for CW keying and who knows if it will reboot or hangup. When my computer reboots, it usually has the LPT port in the wrong state and continuously keys the radio. The other reason is from the old movie, "On The Beach". From Wikipedia: "The story is set in 1964, what was then the near future (1963 in the book) in the months following World War III. The conflict has devastated the northern hemisphere, polluting the atmosphere with nuclear fallout and killing all life. [...] "From Australia, survivors detect a mysterious and incomprehensible Morse code radio signal originating from the United States. With hope that some life has remained in the contaminated regions, one of the last American nuclear submarines, the USS Sawfish, placed by its captain under Australian naval command, is ordered to sail north from its port of refuge in Melbourne (Australia's southernmost major mainland city) to try to contact whoever is sending the signal. [...] "The Sawfish then travels to an abandoned naval installation in San Diego (in the book, it is located near Seattle), where they discover that, although the city's residents have long since perished from radiation poisoning, the Naval base's hydroelectric power is still on-line. The ship's communications officer is sent ashore in a radiation suit to investigate. The mysterious signal is the result of a Coca-cola bottle being nudged by a window shade teetering in the breeze and occasionally hitting a telegraph key." One of the first movies with commercial product placement! Seriously, I always thought that it was good practice and habit to disable the transmitter when not in the room. Even in the room, sometimes it is a good idea. The other day I was listening on the band and had the VOX on. The headset was on the table with the mike connected, but I had the speaker on to just listen as I was doing something else. I sneezed and tripped the VOX. I chuckled when someone, somewhere said "Bless you" over the air! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
