Re: [Elecraft] KX3 and RumLog for Mac
Hi Bill KX3 Mac Utility is working just fine except for AFSK I think user error and will figure it out later. I did see that and had set Baud to 4800 on RumLog. usbserial-A703095C was selected for the port. I had also turned off the KX3 Utility and RumLog is not working. I tried turning off and on the KX3 and RumLog in different sequences and RumLog still does not key the KX3. In RumLog what settings am I missing? -- Jim K9TF __ 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
[Elecraft] K3 RTTY spectrum
For the RTTY people, You may all know already but I did not - therefore this info.

Re: [Elecraft] K3 with KPA500 and KAT500 setup (Training the KAT500)
Hi Sal, Here is a method to train your KAT500: Here is a procedure to set-up the tuner for all bands so that you do not have to go through a Full Search Tuning cycle each time you change to a frequency or band that requires retuning. * Select the desired band on the K3 and find a clear starting frequency near the bottom of the band. * If you are using the KPA500 amplifier, tap OPER to put the amp into STBY mode. * Set up your K3 so it will output between 20 and 100 watts when holding TUNE. * If you are using basic band switching, tap your key to allow the tuner to measure the present band. You must do this before selecting an antenna. If using enhanced band switching, the tuner reads the band automatically. * Tap the KAT500 ANT to select the required antenna. * Tap the KAT500 MODE to select AUTO or MAN. o Tap the KAT500 TUNE. The AUTO or MAN LED will start to flash. o Hold the K3's TUNE to apply power to the KAT500 and it will find the best match that it can and then stop. The SWR LEDs will show the tuning progress and the tuner will stop clacking its relays when it finds the best VSWR. o Tap the K3's TUNE to stop transmitting. * After training the tuner, you should save the configuration file. If you have trouble with your tuner, the configuration file can be sent to Elecraft Support of in-depth analysis. Hint: When training your tuner for various operating frequencies, it is useful and instructive to monitor the tuner's operation with the KAT Utility Operate screen. After doing this on all your favorite frequencies, run the tuner in MAN mode to avoid the sometimes false tuning that occurs when running SSB in AUTO mode.

Not necessarily the best idea for the reasons given by Joe. Among other reasons for *not* using wideband transmit and mousing around the waterfall, take a listen to some of the signals on JT65 or JT9 ... many of them have high levels of broadband noise from their sound cards that may be only 15 or 20 dB below the tone. That noise is also attenuated significantly by the AFSK TX filter resulting is a much cleaner signal (and significantly less QRM). 73, ...

You will have to tune each RTTY signal you wish to call with the VFO. Meaning you cannot leave to K3 tuned to one frequency and wander around the waterfall picking off stations by using for example the MMTTY NET function. It only takes around +/- 300Hz offset from the normal tone pair and your TX output has gone, evidenced by loss of RF output and a vanished ALC reading. The K3 knows nothing about the actual tone pair being passed to it other than what we tell it. Essentially AFSK will need to be used the same as FSK, tuning not mousing.

Re: [Elecraft] Why is KX3 phase noise so much less than the K3 ?
Chris Johnson elecr...@ozy.us wrote: 1) Is phase noise the measurement of the instability of an DDS? That's one contributing factor. But the DDS signal drives a mixer, and the other input to the mixer may be the larger source of phase noise in transmit mode. 2) How does this impact TX only, and why does it create such an issue to nearby listeners? In the case of the KX3 and Flex radios (e.g. Flex 1500/3000/5000), the limiting factor is probably the transmit D-to-A converter. Its performance is limited by quantization and sampling noise, setting an upper bound on phase noise. The KX3 has an advantage in that its synthesizer uses a DDS-driven PLL, while the Flex radios are DDS only, without a following PLL. But the TX DAC is still a factor in both cases.

[Elecraft] KX3 sluggish keyer
Hello folks, I am experiencing from time to time that the KX3 internal keyer is kinda sluggish and misses here and there a dot or the timing is weird. This mostly happens at the beginning of transmissions. I have tried another key (Kent double paddle) with my KX3 and I can exclude it is the stock paddle which has contact problems. The key is working fine on another external keyer. It is extremely irritating and on some transmissions the ATU starts a new tuning cycle (maybe critical tuning on antenna) and exactly in these moments the keyer misses dots or dashes, often more than one. It seems whenever the MCU has too much to do (tuning cycle of ATU, some other task) the interrupts for the keyer input get lost and the actual character is malformed. It happens with MCU firmware 1.87 and 1.94beta. This is an extremely annoying feature which I really would like to go away in one of the next firmware releases. From an embedded developer's point of view I would say that there is too much code executed in interrupt service routines that block the MCU from executing the keyer timing correctly. I have found that parts of the stock paddle have been swapped out to reduce the problem but in my opinion this will not cure the problem. Since contact problems are contributing to the problem one might experience a better keyer timing with exchanged or filed contacts at the paddle but the sluggish feeling is still there. I know that this is hard to find in the MCU firmware but there is one directive a firmware developer should follow: When entering an interrupt service routine interrupts must be disabled. *No* code should be executed within an interrupt service routine, instead flags should be set which enables the main loop to execute code depending to that interrupt. The interrupt service routine itself should be left as fast as possible and interupts should be re-enabled as fast as possible. It could also be a problem with some software debouncing algorithm that is used on the keyer input lines. Without seeing any source it is hard to tell where the problem is. I hope that I gave a hint to the developers to look for? vy 73!

Re: [Elecraft] K3 RTTY spectrum
The AFSK TX Filter cleans up any hum on your sound card from bad connections, grounding issues, or distortion from over drive. However, with the K3 one can get the same narrow transmit spectrum by using FSK without the issues of AFSK. Written by Joe Subich, W4TV Not as I read the article - but I may be wrong. Effect of the K3 AFSK Transmit Filter Rather than hacking the K3 to transmit through a narrow roofing filter, an equal or better result can be had by simply enabling the AFSK transmit filter in the configuration menu. This places a 400 Hz filter before transmit audio arrives at the RF modulator (this only applies to AFSK-A mode, not DATA-A mode). This filter is centered around the tones configured under the radio's PITCH menu. The effect is similar to what MMTTY and other programs do in their software, but this is done in the radio's DSP firmware. The radio's manual says this filter can serve to filter any noise that might be on the audio input, and it certainly will do that, but it has the additional benefit of filtering keying sideband energy. Figure 9 shows the result of MMTTY's unfiltered phasecontinuous AFSK audio into the K3 with the K3's AFSK filter enabled. Comparing Figure 9 with Figure 3 demonstrates the effect of the K3's AFSK filter, as both have exactly the same audio input to the K3. Attempts to overdrive the radio resulted in no significant change in signal bandwidth. Even when transmitting wideband noise into the K3, the AFSK filter limits the bandwidth. While it is possible to transmit trash that is difficult or impossible to copy, the K3's AFSK filter makes it unlikely that it would generate much interference on adjacent channels. An important point: Even given the K3's transmit IMD, the occupied spectrum using shaped FSK is much narrower than that when using the internally generated FSK synthesizer. FSK keying sidebands are not unique to the K3; every radio that uses phase-coherent for its internal FSK generator will generate a wider spectrum at essentially any power level. The only differences will be in cases where the IF filter cuts off the sidebands. As an experiment, I decided to see just how wide I could make my signal by overdriving the K3's line input. I cranked the PC's headphone output to 100 percent and drove the ALC as hard as I could by setting the line input gain to maximum (see Figure 7). Some strange spurs show up in the spectrum, but even those are below the keying sidebands of the FSK transmitter (see Figure 2). Even trying to transmit absolute trash I wasn't able to make the AFSK Figure 4 - AFSK with MMTTY using a 512 tap TX BPF with a passband of from 2000 to 2400 Hz, 0 dBm Figure 5 - AFSK with MMTTY with 512 tap TX BPF, 100 W signal as wide as that of the internal FSK generator. The rise in the noise floor over the 2.8 kHz bandwidth occurs, because the K3 amplifies noise from somewhere; at this gain setting it is present whether or not anything is plugged into the K3's line in jack. This behavior is almost certainly specific to the K3, because the K3 scales audio in DSP before it ever enters the RF stages. Other radios are not going to protect you from yourself nearly as well, so you might expect harmonic distortion and other bad things with no limiting prior to the point of RF modulation.

Re: [Elecraft] K3 RTTY spectrum
Not as I read the article - The article was written before the latest update to the K3 FSK generating DSP code in MCU 4.66 released 2013-03-22. The article is simply out of date. The release notes for 4.66 say: FSK-D KEYING BANDWIDTH GREATLY REDUCED: This change reduces the amplitude of the FSK-D keying sidebands by 25-30 dB at 500 Hz offset, giving teh K3 one of the cleanest FSK signals available. The author of the NCJ article reviewed the K3 firmware while it was still in beta here: http://www.frontiernet.net/~aflowers/k3beta/ The author's own web page contains the information in the NCJ article here: http://www.frontiernet.net/~aflowers/k3rtty/k3rtty.html By comparing the before and after spectrogram in the K3beta article with the before, 2-Tone, and filtered MMTTY spectrograms on the AFSK Bandwidth with waveshaping page in the original article, you will see that the new K3 FSK code is every bit as clean as the wave- shaped AFSK *without* the problems associated with AFSK. Note that the author's article on the web page shows the benefits of the K3 AFSK TX filter in terms of being able to clean up all manner of *intentional* abuse to the AFSK audio - abuse that would render the AFSK signals from other transceivers an absolute festival of QRM. Here is what the author wrote of the new FSK code: Notice that the unshaped [original - W4TV] keying has clicks that will result in an S7 noise floor at 500 Hz spacing that very gradually flattens out to an S4 noise floor 1 KHz each side of transmitter, which is eventually limited (we hope!) by the IF filter in the transmitter. This makes it easy to see how loud signals placed every few kilohertz raises the noise floor of the entire band for everyone. The BW-reduced [new code - W4TV] signal is under S2 at 500Hz and drops off very rapidly into the noise as one tunes away. It is below the S1 noise floor of the receiver when tuned more than 700 Hz away. 73, ...

Re: [Elecraft] KX3 sluggish keyer
Sven, This has nothing to do with interrupt routines, etc. When you transmit, the KX3 first checks to see if you have moved the VFO to a new band segment for ATU purposes. This is typically every 20 kHz, but may be a smaller or larger increment depending on the band and on whether you have trained the KX3 at multiple points within a band. If the KX3 finds that new L/C data is available for the segment you're now transmitting in, it must retrieve that data and send it to the KXAT3 module. The KXAT3 has latching relays, so it takes a significant fraction of a second (up to about 200 ms) to do all of the relay updates. In non-CW modes, this L/C update is done immediately, since a one-time delay of this length is usually of no concern. However, in CW mode, a 200-ms delay can interrupt keying. So we had to choose between two options: 1. interrupt the first character sent 2. attempt to insert the L/C update between words We chose the latter. As soon as there appears to be a word-space-length pause in transmission by the operator, the KX3 will send the new ATU data to the KXAT3 and flash the ATU icon a couple of times. In practice this works well most of the time. You may be noticing the effect of leaving a word-lengh space, but starting to key the radio just before it has completed ATU update, which of course holds off transmission. In a future firmware release we may allow the operator to select automatic L/C updates during VFO tuning. The sound of relays updating occasionally as the VFO is tuned would be objectionable to many, which is why we didn't do it this way initially. If we add this feature, you'll need to select it with a menu entry. 73, Wayne N6KR On Jun 9, 2014, at 9:57 AM, Sven Ladegast s...@ladegast.info wrote: Hello folks, I am experiencing from time to time that the KX3 internal keyer is kinda sluggish and misses here and there a dot or the timing is weird.

Re: [Elecraft] Why is KX3 phase noise so much less than the K3 ?
Thanks Wayne and Alan, for that super detailed info. The radio side of things are still very magical to me! I'm a software guy, not a hardware guy. :) I don't own a K3, but two KX3's for my knob radios. I use a Flex 6700 and 6300 for home use. I'm assuming the 6700's -147 dBc@10kHz, -152 dBc@100kHz phase noise values are pretty good then, if anything higher than -140 dBc is acceptable. Even the 6300 is spec'd at -140 dBc@10kHz. I do agree that my old (and sold) 3000 was messing up the bands during Field Day last year. This year we are using a K3, two 6300's, and a 6700, so I'm hoping for better performance all around.

Re: [Elecraft] Hard Case for K3
A lot of people have used various Pelican Cases which apparently give good protection at a moderate price. I elected to buy an aluminum case from Home Depot which they have for about $20. This case has ample room and is adequate for Field Day and such, but airline travelers might prefer the better protection of the Pelican. One wife of one of the members makes some cloth covers and dust covers which a lot of K3 owners like and I think they can be customized to your liking, but probably are not the best for rough handling.

Re: [Elecraft] KPA500 and KAT500 setup (Training the KAT500)
Hello again on the training of the KAT500: Don W3WPR points out that I forgot to mention that each band has segments for which you should find the tuner settings. The segment widths are: Below 3 MHz -- 10 kHz 3MHz to 26 MHz -- 20 kHz 26 MHz to 38 MHz -- 100 kHz 38 MHz to 60 MHz -- 200 kHz You should train the KAT500 on at least one frequency in each segment. For example, on 20 meters, start at about 14.010 and then move up the band in 20 kHz jumps to fully train the tuner for the entire band. Of course you don't have to train it for the whole band or every band if you don't operate on some frequencies. 73, Fred KE7x -Original Message- From: Slava Baytalskiy [mailto:sla...@nullserv.com] Sent: Monday, June 09, 2014 9:53 AM To: Cady, Fred Cc: Elecraft Subject: KPA500 and KAT500 setup (Training the KAT500) Thanks, Fred!

Re: [Elecraft] KX3 sluggish keyer
Hello Wayne, Many thanks for your answer! This sounds exactly like my problem. Since I am using the KX3 with different antennas it could be that the ATU used old parameters found from one of my other antennas and sent these values to the relays when I start to transmit though I had a perfect match some kHz away before. This at least explains why the ATU starts a tuning and ends up with a bad SWR occassionally plus having a little lag before transmission starts.. Until now I did not utilize the memory clear function for the ATU but I think that clearing memories after using a new antenna would solve this problem completely for me. I am using iambic mode B with the keyer and if I have some kind of little pause between the dits and dahs during keying the MCU could recognize this as the first word pause and update L/C-data to the tuner which results in an interrupted first character. Setting the ATU to bypass should also prevent the above problem and should make keying as responsive as normal. Additionally I will try to sand the contact screws to a convex contact shape as well as adding 2 wires from the GND pad to the each lever's spring holder screw to improve contact reliability. Many thanks for your explanation Wayne! It just felt the way that the MCU was missing keyer input. Thats why my idea with the interrupts... Being an engineer is not that easy...you'll always find new problems to already available solutions! Hi 73! Sven, DJ2AT Wayne Burdick n...@elecraft.com schrieb: Sven, This has nothing to do with interrupt routines, etc. When you transmit, the KX3 first checks to see if you have moved the VFO to a new band segment for ATU purposes. This is typically every 20 kHz, but may be a smaller or larger increment depending on the band and on whether you have trained the KX3 at multiple points within a band. If the KX3 finds that new L/C data is available for the segment you're now transmitting in, it must retrieve that data and send it to the KXAT3 module. The KXAT3 has latching relays, so it takes a significant fraction of a second (up to about 200 ms) to do all of the relay updates. In non-CW modes, this L/C update is done immediately, since a one-time delay of this length is usually of no concern. However, in CW mode, a 200-ms delay can interrupt keying. So we had to choose between two options: 1. interrupt the first character sent 2. attempt to insert the L/C update between words We chose the latter. As soon as there appears to be a word-space-length pause in transmission by the operator, the KX3 will send the new ATU data to the KXAT3 and flash the ATU icon a couple of times. In practice this works well most of the time. You may be noticing the effect of leaving a word-lengh space, but starting to key the radio just before it has completed ATU update, which of course holds off transmission. In a future firmware release we may allow the operator to select automatic L/C updates during VFO tuning. The sound of relays updating occasionally as the VFO is tuned would be objectionable to many, which is why we didn't do it this way initially.

Re: [Elecraft] KPA500 and KAT500 setup (Training the KAT500)
I trained my KAT500 right after I built it, I run it in MANUAL, and it's about as perfect as you can get. I don't think I've ever asked for an additional feature, so here goes: I use a C-R dipole @~65 ft for 40, 30, 17, and 12 [the GAP Titan is just too noisy on those bands]. I built it from two lengths of 450 ohm window-line. Works great ... like a fan-dipole, it has a dipole pattern on all bands instead of squirting my RF in undesired directions on 17 and 12. The problem: 450 ohm window-line is somewhat sensitive to rain, fog, snow, ice, and other forms of wetness. Thus, I need to re-train at the beginning of the rain, and again when summer arrives [almost never rains in the N. Cal Sierra foothills from about May to Oct]. So, 1. Two banks of EEPROM to store separate training values. As an accessory would be fine for me, a lot of folk have stable antennas and, in the Elecraft Ethic, should not have to pay for it if they don't need it. 2. As an alternative, add a Train Your KAT500 option in the KAT500 Utility. Upside is that doing it manually takes quite awhile. Down side is that your 20W tune signal is sure to step very briefly on someone somewhere since the Utility won't have any good way of know if the chosen training frequency is occupied [Don't use 14230 or 14300 :-)]. The Utility could maybe allow you to select segments used [mine would all be CW] which would lessen the on-air impact. And now, I await someone telling me that the KAT500 Utility already does this. I don't see it there, but I've overlooked a lot of features on my Elecraft gear.

Re: [Elecraft] Expecting a delivery ... but didn't happen
We have a similar situation here - on a private road - and I do believe the numbers were randomly assigned. Coming down the road, one sequentially encounters 1062, then 1060, then 1063, then 1064 - 1061 has been passed 1/4 mile before and there are intervening numbers between. Somehow USPS, UPS and FedEx have figured it out. Google Earth has it right, but most GPS units lump all those addresses in the middle of the road. So we have not had a problem with the carriers, but I am not sure how they have figured it out. The department that assigns addresses is connected with the USPS delivery addressing system, but I do not know the order - to me it seems quite arbitrary, but there must be some sensibility in what appears to be chaos.

Hi all, For those who didn't go to Sea Pac and see the new options here is a visual report. The 2/4m option is the credit card size mounted on the ATU module. It's not much over 1/8 in thickness. I don't know if it was the 2m or 4m option. Suspect it was a 2m. The PX3 looks like shrunken P3. The front looks the same just smaller. The I/O is on the left side with lots of ports. The cabling needs to have right angle plugs on both ends as the units will be spaced out quite a bit. I was able to get Dick to open the PX3 to check out the internals. NO batteries external power only. There is some room inside, but who knows what other options will go inside? Like the P3 when first introduced maybe in the future Ext monitor card. There was two boards inside one next to the screen and another smaller card for power and I/O. The power uses the similar plug and cable used on the KX3.
