[Elecraft] K3 - 'Unwanted' TX Gain calibrations?
Been wondering just how the TX Gain calibration works. To quote from the manual - "The gain constant is updated whenever the TUNE function is activated on a given band at one of three specific power levels: 5.0W, 50W, and 1.00 milliwatt." So if I'm adjusting my external ATU by TUNE(ing) at say 5watts, will the (LP)Tx gain constant be updated while feeding into an unspecified load. The described procedure requires the use of a dummy load to set the gain constant; if the load isn't 50 ohm resistive will the constant be set to some anomalous figure which may not be updated when the atu eventually presents (hopefully) 50R to the K3??

Re: [Elecraft] K3 AGC is better now
Can anyone recommend the best menu setting for max discrimination among many callers at same time? Start with Config menu: AGC SLP= 005 and then experiment with different values. The lower the value (down to 0), the louder the stronger signals will be. If you go too low, you risk overdriving your ear drums. I found that we can go down (even to 0) without risking the ears, if we set high threshold (AGC THR up to 8). This allows us to crank down AF gain control (9 o'clock here for 200 Hz BW). 73, Val LZ1VB ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I hope not - though it could explain a few things. Surely the radio needs to be in TECH mode. Tuning up an ATU would reset all the calibrations otherwise.

Re: [Elecraft] A Bad Thing Happened To My K2
Mark, I am puzzled since you say it transmits on 40 meters, but does not receive - and that it receives well on other bands. There is precious little in the K2 that would create that situation. What do you have set for 40 meters that is different from other bands? Preamp on/off? Attenuator on/off? RANT on/off? Do you have the K160RX installed? If so, connect your antenna to the receive antenna jack and see if the receiver comes to life. Now if you could not transmit nor receive on 40 meters, I would point to the relay in the 40 meter lowpass filter, so check 40 meter transmit again - and check all bands for the maximum power produced. Sometimes a transmit problem will not be revealed by transmitting at a low power level, but will reveal itself when the power control is cranked to maximum. Do you have the KAT2 installed? If so, try removing the KAT2 and see if you can receive 40 meters from the base K2 antenna jack. Other than those things, I am out of ideas. 73, Don W3FPR Mark Saunders, KJ7BS wrote: This evening I had a guest ham in the shack who was curious about my K2 and asked if we could hook it up. So we did. I pointed out which 12v power strip, power cord, and antenna to use. While I was getting the proper computer interface cables hooded up, my guest connected the radio to the power and switched it on. I heard a loud snap and immediately looked in the direction of the K2 operating position. My guest had a strange look on his face and I asked what happened. There was a spark from the outside of the antenna connector on the back of the K2 to the center connector of the coax. That can't happen, right? Wrong. After shutting down the power supply and inspecting things, I discovered my guest had wired the power backwards. Fortunately the reverse polarity circuitry protected the radio and internal battery. The radio was operating from the battery, that's why it came on. I still can't understand where the spark came from. However, I now have virtually NO receive on 40m, that's where the radio was when the spark occurred. I have transmit and receive on all other bands and transmit on 40m, just no receive on 40m. That spark killed something dealing with 40m receive. It is so bad I can't even hear the local oscillator around 7000 KHz with the pre-amp on. There is no CW or SSB receive. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Been wondering just how the TX Gain calibration works. To quote from the manual - "The gain constant is updated whenever the TUNE function is activated on a given band at one of three specific power levels: 5.0W, 50W, and 1.00 milliwatt." I'm surprised there have not been any comments on this matter as it's an excellent question. To Stewart's point, does the gain of the K3 recalibrate every time TUNE is depressed at one of the three stated power levels when the CONFIG menu is set as instructed in the alignment section of the owner's manual for "PWR Set = nor?" Does the K3's display need to reflect "PWR Set" simultaneously for the calibration to occur, or can we exit from the CONFIG menu prior to the gain alignment so long as "PWR SET - nor"? Finally, what prevents the re-loading of new gain data if as Stewart suggest, he sets the K3 power to exactly 5 watts or 50-watts and depresses TUNE for external ATU tuning purposes? Should he instead stay away from those two values and use perhaps 49 or 51 watts? I am running into the same issue as my K3's 10M output power appears to be substantially less (~ 75W) than on lower HF bands. I would like to ensure that I have calibrated gain for 10M and 6M and know that the routine was invoked as expected.

[Elecraft] SDR-IQ + K2
Mike wrote: +++ "I was wondering if anyone on the list is using the SDR-IQ software defined radio and what their thoughts are on it. Can CW Skimmer be used with it? Does it have to run through my K2? So and so forth. I don't use cw skimmer but I do contest a lot and would like to know how much woule it really help." Picked up a SDR-IQ some time ago for use as a general coverage SW receiver. The SDR-IQ is the size of a pack of playing cards. The packaged control software, SpectraVue, is highly capable and works beautifully with a plain vanilla, 5 year old Dell laptop (XP Pro)through one of the USB ports and using the on board soundcard. Highly recommend the SDR-IQ for on the go HF, 500 hz to 30 mhz, all mode SWLing (AM, USB, LSB, DSB, CW). Comparable in performance to a R-71A. Several months ago added a Cliffton Laboratories Z1 IF buffer-amplifier / tap to the K2 (w/KIO2 RS-232 interface)and frequently use the SDR-IQ as a panoramic spectrum monitor. This is an easy modification and Cliffton Labs provides outstanding support (also highly recommend). Typically, use the SDR-IQ + K2 combination to monitor about 150 khz of spectrum for general activity. For example, in the evenings, generally observe 30 to 40 cw sigs in the segment from 7.0 to 7.15 mhz)-- 4 or 5 closely spaced is a good tip that dx is present. A mouse click at that location on the laptop screen will take the K2 instantly there to check what is going on. More often, use the SDR-IQ to simply check for a clear space to CQ or to find an interesting QSO to listen in on (the laptop screen resolution is plenty adequate to visually decode cw if desired). In summary, the SDR-IQ and K2 (with Z1) work and track very well together. Have not used cw skimmer but, could. Not of interest for contesting as this technology, imho, is "assisted" whereas just me and the radio (plus laptop with no spotting clusters attached)is preferred for this activity. This month's issue of the NCJ has several very good articles on SDR-IQ setup and utilization. 73, Chuck AF4PP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 SSB Power Control and ALC Metering
There's been some recent discussion of how to properly set up the K3 in SSB modes. I meant to respond sooner but was out of town for several days. MIC GAIN SETTING: Adjust MIC gain for an ALC meter peak at around 5 to 7 bars during normal speech (rev. D owner's manual, page 28). This applies even to TX TEST mode, meaning you can set it off-air. This indication does not mean that you're "hitting the ALC really hard." When you get to around 5 bars, you'll be "tickling" the DSP's ALC. More on this below. ALC METERING: The K3's ALC meter is a bar graph, not an analog meter, and we felt that 5 bars would provide the right granularity at the target ALC level. The 5th bar of the ALC scale is heavier than the others, serving as a reminder of the this level. ALC DESIGN GOAL: The K3 was designed to minimize transmit splatter and other effects that plague some rigs. To achieve this, we apply all ALC *before* the crystal filter, and minimize the application of ALC in general. The levels have been carefully calibrated to that 5-to-7-bar level mentioned above. The result is that the crystal and DSP filters remove the types of artifacts that in many other rigs end up as transmitted wideband noise or clicks. I believe this is why we continue to hear excellent reports from K3 users regarding their on-the-air SSB signals. (We've also heard, from some experts in the subject, that the K3's compression is among the most effective they've ever measured.) PER-BAND POWER CONTROL: With some vocalizations, speech energy may build up within a narrow crystal filter to produce a slight peaking effect. Because of this, the user must set the K3's power output level such that it peaks at or below the safe level for any external amplifier under all speech conditions. To facilitate this, you can use per-band power control (refer to the PWR SET configuration menu entry). We have many customers using this method. It compensates for per-band gain variation in the external amp or the K3 itself, again reducing the need for ALC. For example, all crystal filters have a small amount of ripple (typ. +/- 0.5 to 1.0 dB) that can result in a slight difference in average power output between LSB and USB with some voice characteristics. But since you typically use only one of the two sidebands on a given ham band, per-band power control can conveniently compensate for small variations. TX GAIN COMPENSATION FOR VOICE MODES (TXG VCE): If you find that your speech peaks are routinely above the desired level (i.e., higher than CW power output using TUNE), you can adjust the TXG VCE menu parameter downward in 0.5 dB steps. Conversely, if your normal speech characteristics result in lower power output compared to CW TUNE, you can increase TXG VCE above the 0.0 dB level. I'll be happy to answer any further questions. Our goal is to improve the manual to make the above as clear as possible. 73, Wayne N6KR * * * OK?

[Elecraft] Re: K3 - 'Unwanted' TX Gain calibrations?
Hi Paul, Been wondering just how the TX Gain calibration works. To quote from the manual - "The gain constant is updated whenever the TUNE function is activated on a given band at one of three specific power levels: 5.0W, 50W, and 1.00 milliwatt." To Stewart's point, does the gain of the K3 recalibrate every time TUNE is depressed at one of the three stated power levels... ? Yes. It doesn't matter whether you select one of these power levels manually using the PWR knob, or using the TUN PWR menu entry. It will always recalibrate the gain constant during TUNE if you happen to be at one of these power levels. However, it will only do this if the SWR is 2.0:1 or less. This provides plenty of safety margin. Finally, what prevents the re-loading of new gain data if as Stewart suggest, he sets the K3 power to exactly 5 watts or 50-watts and depresses TUNE for external ATU tuning purposes? Should he instead stay away from those two values and use perhaps 49 or 51 watts? No need to do this. The fact that it recalibrates every time you do TUNE at one of these levels is not a problem. It just updates the EEPROM constant if it has changed. The TX gain constant is only there to compensate for small per-band gain variation within the K3's transmitter. If you've done the power calibration, then you can set PWR and be fairly close to the target level on each band. Thus the MCU won't have to adjust power very much in real time. In CW mode, this means we can apply our keying waveform open-loop, preserving the target raised-cosine shape at all power levels. In voice modes it helps achieve our goal of applying a minimum of ALC. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 (gasp, a real K2 question) KPA100 idea
John, As long as you use a good socket, there should be no adverse effects - all the signals operate near DC or very low frequencies. Long term there is always more of a chance for oxidation between the chip leads and the socket than with a properly soldered-in chip, so you may want to re-seat the chip every 2 to 3 years just to wipe away any possible oxidation - it really depends on 'the air you breathe' how rapidly oxidation can develop - the coastal salt air seems to accelerate it. 73, Don W3FPR [EMAIL PROTECTED] wrote: If I install an IC socket for U2 on my KPA100, will there be any adverse effects?

Re: [Elecraft] Re: K3 - 'Unwanted' TX Gain calibrations?
Wayne, I agree that the K3 can easily be made to transmit excellent audio, and I've been getting glowing reports on mine. I have a question. Exactly where in the signal chain is TXEQ with respect to Line In, Mic In, Comp/Lim, and the sensing for VOX? The absolute best place for TXEQ is after the point where the Mic In and Line In are summed to feed VOX sensing, with Comp/Lim following that. Is that the existing flow? Are there different settings for Line In and Mic In? I would expect (and hope) that TXEQ is disabled for digital modes. 73, Jim K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Re: K3 - 'Unwanted' TX Gain calibrations?
MIC|LINE|DVR are summed, The result is sent to the VOX detector as well as to the Tx Audio filter, which includes the TxEQ. If the VOX detector were driven after the filtering, there would be delay. This way, the filter delay acts to improve VOX attack time. Tx EQ is a global control at this time. It does not currently change with mode or source. It is up to the operator of the radio to set it correctly for the mode and source of the moment. This is one of the many items "on the list" for future enhancement. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Yes, but it also prevents the TXEQ filter from removing LF trash (breathe pops, mic handling noise) that false triggers the VOX. And I'm having that problem. For the same reason, we want the comp/lim to be after the TXEQ. Have you considered (and are you using) "feed forward" sensing for comp/lim? This is widely used in pro audio. A few ms can do a lot to catch fast peaks, and it's analogous to what you're doing with the delay associated with EQ.

Compression is after the filtering. It is feed-forward. VOX is before the filtering.

Does the K3 include a "wattmeter slope" adjustment? If so, I can't find it. When the wattmeter is calibrated on 20 meters, I find a .75 to 1 dB slope between 1.8 and 50 MHz when compared with both my LP-100 and Bird wattmeters (power is about .25 dB high on 160 and a bit more than .5 dB low on 50 MHz). The slope appears to be consistent at both 5 and 50 watts. If a slope adjustment is not available, it might be worthwhile to add the option to calibrate the wattmeter at two (160/10 or 160/6) or three points (160/20/6) for frequency compensation. 73, ...

Re: [Elecraft] Re: K3 - 'Unwanted' TX Gain calibrations?
Wayne, Ahhh...I think I see now. In effect, it's really an ALC loop gain calibration, with ALC gain optimized for each band -- correct? This sounds very similar to what Ten Tec is using with their Omni VII, only their calibration is conducted once at the factory to achieve optimum band-by-band ALC gain. Their rig also nicely preserves the raised-cosine CW waveform at all power levels. For some reason, I had this thought in my head that forward gain between say the driver stage and PA was being changed in the firmware, irrespective of the ALC. Perhaps it was the "TX Gain" nomenclature... Also, after the TX Gain calibration, I am seeing about 75-80W (with PWR set to 100W) on 10M and 6M into my Bird TermaLine load and measured with LP-100 and Alpha 9510 WM. No big deal but I just wanted to know if this is a normal unit-by-unit variation? This may, or may not be correlated with Joe's comment concerning WM slope.

So we did. I pointed out which 12v power strip, power cord, and antenna to use. While I was getting the proper computer interface cables hooded up, my guest connected the radio to the power and switched it on. I heard a loud snap and immediately looked in the direction of the K2 operating position. My guest had a strange look on his face and I asked what happened. There was a spark from the outside of the antenna connector on the back of the K2 to the center connector of the coax. That can't happen, right? Wrong. After shutting down the power supply and inspecting things, I discovered my guest had wired the power backwards. Fortunately the reverse polarity circuitry protected the radio and internal battery. The radio was operating from the battery, that's why it came on. I still can't understand where the spark came from. However, I now have virtually NO receive on 40m, that's where the radio was when the spark occurred. I have transmit and receive on all other bands and transmit on 40m, just no receive on 40m. That spark killed something dealing with 40m receive. It is so bad I can't even hear the local oscillator around 7000 KHz with the pre-amp on. There is no CW or SSB receive.

RE: [Elecraft] K3 power cord
It's a separate kit included with your K3 gratis exactly for people like yourself who don't have extra APP cables lying around. That's why you don't find it mentioned in the K3 manuals.

The only thing I see that is common to transmit, receive and the RX antenna and is only in circuit on 40 meters is the Band Pass Filters - particularly the toriods L1 and L2. If you had not said the RX Ant was also dead, I would suspect L25 and/or L26 in the Low Pass filter. If you have a separate antenna for 40 meters and are connecting it to the receive antenna for testing, I would also check the antenna (or tuner). > My guest had a strange look on his face and I asked what > happened.

This would indicate a DC path through the secondary of the PA output transformer, (RF board), through the LPF and to the antenna connector. With +12V on the chassis (reversed power supply), I can see damage to one or both of the toroids in the LPF, damage to relay K12 or damage to the antenna system (balun?). 73, ...

[Elecraft] k3 shipment
Well my K3 was shipped today, but according to ups it is going to an address that doesn't exist. The box could have the right address on it and ups just made the mistake when they sent me the notification that it is being shipped. Or it could end up at who knows where? Who knows? I'm beginning to think I am snake bit! Scott N5SM ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
