[Elecraft] S-meter read S9 with no signal
I built my K2 yesterday. It worked right away but the minimum S-meter reading is S9, even with no antenna. With signals it easily goes to +60. The SMTR settings are default. I tried fiddling with them but it seems the problem is elsewhere. RF gain action is awkward. When decreased all the way the S-meter goes to +40 but not S60. The radio seems more noisy than Mark V Field. Still, one can hear an increase in noise when the preamp is turned on. Have I messed up something in installation?

[Elecraft] UK Elecraft net report for Sunday 30th November
There were quite a few stations on the new, I would have expected less as it's CQ WW this weekend. Topics covered included vat issues and shipping issues when sending a transceiver back to Elecraft for repair (http://www.hmrc.gov.uk/vat/int-processing.htm partly covers the issue), The recently announced K3 audio modifications and whether the choke really makes much difference, Softrock hints and tips, rattles from the K3 internal speaker, making antenna splitters and interfacing other receivers to the K3, the disk space used to record a band using a Perseus SDR receiver, plus a puzzle as to why one net member seemed to be 70 - 80 Hz high in frequency on transmit with his K3. Stations this week were: G0VGS, Ian G4NWJ, Jim G0MJW, Mike G4SJP, Stephen G4IDA, Bernie G4ERO, Collin G4APO, Rowland G0GJH, Andrew G3NIC, Ken 73 until next week.

Re: [Elecraft] S-meter read S9 with no signal
There are no 'default' settings for the S-meter. The adjustment procedure is in the manual. Do these steps in the order listed. 1) Set the AGC Threshold to 3.80 volts measured at Control Board U2 pin 5 Note - if your 8 volt regulator is on the low side of its specification you will not be able to achieve the 3.8 volt reading - in that case, measure the 8 volt regulator output voltage and calculate 45% of that. Set the AGC Threshold to that voltage. 2) With no antenna connected, turn the RF Gain control to maximum (full clockwise), then enter the menu for CAL S LO. Set the menu parameter one count above the value where the left bar turns off. Exit the menu. 3) Turn the RF Gain control to minimum (full counterclockwise), then enter the menu for CAL S HI. Adjust the menu parameter to just illuminate the rightmost bar of the bargraph. Exit the menu. 4) (Optional) If you have a calibrated signal generator that will produce a 50 uV output at a frequency the K2 can tune to (preferably 40 meters), tune that signal for maximum S-meter reading with the preamp off. If the S-meter reading is different than S-9, adjust the CAL S HI menu parameter to produce an S-9 indication. If you cannot achieve these results, that is an indication that you need to do some troubleshooting. 73, Don W3FPR Ignacy wrote: I built my K2 yesterday.

[Elecraft] [K3] VGA cable - beware
I am preparing to install an amplifier on my K3. To get the ALC signal from the 15 pin DIN plug I was hoping to use a VGA cable, cut one end off, and wire it up accordingly. Unfortunately pins 3,4,5,6,7,8 and 11 are all grounded in the cable. There are 4 shielded wires in the cable and the ground foil on the outside. So I will have to cut off the offending pins or spring for a male connector. Monty K2DLJ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 frequency calibration
After participating in the UK Elecraft net briefly this morning, and feeling that with the vfo 'on the nose' voices were a bit too low pitched, I thought I would check the vfo calibration against the Russian freq standard on 4996kHz. Using spot as reference and listening for the beat tones, the K3 had drifted down by 10Hz. I set it when I first had the rig in June so it's had time to settle down a bit now. I think a 10Hz drift is pretty reasonable given that I don't have the higher stability reference option. It was quick and easy to adjust too.

[Elecraft] K3 RX AGC right after a transmission
During the CQWW CW we found that RIGHT AFTER a transmission the RX AGC was STILL busy doing its job and getting back to a lower level (s-meter dropping from about s9 to the band noise level) (AGC was at slow). We SUSPECT that the AGC was still at the level from BEFORE the transmission. So working a strong station gives a problem if the next one is weak, you'll miss the first letters of the call. We're not sure about the cause but we encoutered this problem quite often. It would be better that after a transmission the RX would start at band noise level and that there is no legacy whatsoever. Anyway, the work around was setting the AGC to fast. Did anyone else experience this? Is this a known problem? Setting agc: threshold 5, the AGC ramp-up at 12, the fall-off setting at default value (20) SW: latest Beta.

Re: [Elecraft] S-meter read S9 with no signal
Ignacy, There are a number of possibilities causing the high S-meter reading. Were you able to adjust the AGC Threshold to the correct voltage? What was the result when you adjusted the CAL S LO and CAL S HI menu parameters (were you able to get the correct bar to illuminate - or extinguish)? What happens to the S-meter reading if you turn the AGC off? What happens to the S-meter reading if you place a jumper between pins 1 and 2 of the J10 header (or the J10 header location)? The answers to the questions above will be an indicator of where to begin looking for the problem. 73, Don W3FPR Ignacy wrote: I tried SMTR settings but none can bring the S-meter below S9.

Re: [Elecraft] K2/100 unstable power...
Paul, That is the correct fix for the problem. The K2 controls power using a control loop that includes the entire transmit chain. The control loop is stable with the base K2, but when the gain of the KPA100 is added, the control voltages can overshoot - just how much depends on the gain of a particular K2/100 when operated at the high power setting. Since the transmit gain is usually greatest on 40 meters, you will likely notice the problem more there, and it will be at its minimum on 10 meters where the gain is less. The exact gain will vary depending on the particular component tolerance mix and the amount of careful construction used when building the K2. Increasing R98 will dampen the loop response, but be careful not to go too high or th epower output on 10 meters may never get up as high as it should. Decide how much you are willing to impact the 10 meter power output and use the highest value resistor at R98 that still allows that power on 10 meters. Each K2 is different (because of slight differences in gain). Some will adequately dampen the loop overshoot with the normal 270 ohms while others can use a value as high as 1500 ohms at R98. Determine the best value for your K2 by testing with a temporary pot as indicated in the Power Control Mod instructions. 73, Don W3FPR IK1QHB wrote: Hi folks I have end to build the KPA100 few days ago but there's a problem to fix.

Re: [Elecraft] External speakers?
Tim, Not addressing the aesthetics of the speakers, but pointing out other considerations. In addition to the K3, do you have other audio sources that you want to listen to while in the shack? If the answer is 'yes', you may want to consider something like I have here - reasonably good stereo speakers (mine are the old RS Solo-3B) that are fed by an audio power amplifier. Ahead of the amplifier is a Behringer 802 mixer that has inputs from an FM tuner, a tape deck, and the K3 as well as connections in and out of the computer soundcard. The sound is great. The soundcard feeding the mixer is different than the one connected direct to the K3 line-in/line-out for use with digital modes. I cannot comment on the RF immunity of this setup. My antennas are all resonant and located more than 80 feet from the shack, so there is little possibility of RF in the shack. Others with non-resonant antennas close to the shack location may experience problems. Consistent with Jim Brown's (K9YC) recommendations, the computer is bonded both to the radio and the mixer, and they are all powered from the same AC outlet. 73, Don W3FPR NZ8J wrote: I would like to use two external speakers with my K3 setting them up one on each side of the radio.

Re: [Elecraft] K3 changing RX filter during transmit
Arie Kleingeld PA3A wrote: During CQWW CW we fiddled with the K3 filter settings a lot. Both Ad PA8AD and I repeatedly wanted to change the filter setting during the last transmission of the QSO (the TU PI4D), anticipating the next QSO. During transmission the RX filter controls are locked. So, can the filter controls be unlocked please. This will be more pleasant for operating. This is probably the single most requested firmware change by the field test group. Wayne has promised that he will take care of it.

Re: [Elecraft] K3 - Spontaneously changing config?
Down the years I have found that flashing a new BIOS on computer motherboards can also occasionally generate a surprise change or two. Why this should be I have never discovered but, eg, having your boot media priority changed can cause a distraught hour or two for the unwary. Yeah, the rule of thumb is leave the bios alone unless you have a really good reason for updating it.

[Elecraft] K3 Serial Numbers
Hello, I am considering purchasing a K3 in the 300 serial number range. Have there been any circuit improvements to the radio since that I should be aware of? Thanks for any advise.

Re: [Elecraft] K3 AFX
Arie: During the CQWW CW we used my K3 at PI4D and tried out the AFX. Very nice feature when the frequency is as crowded as in the CQWW. Pity the sidetone (monitor) is normal mono. ONLY if you are using a single speaker. With dual speakers, AFX works nicely! I suggest that if AFX is enabled the monitor audio is also in AFX-sound so you can stay 'in flow. 73, Tom N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] External speakers?
Yeah, I have a pair of LabTech SS-700 speakers that I've had around for quite a while. They are black, just about the same height as the K3, and sit nicely and unobtrusively alongside the rig. While they have amplifiers, it leave it off so they operate straight through. They sound FB. Those are old speakers, but they're still around. Shoot, I just checked and saw a brand new pair still in the original box offered on e-bay for a current bid of $0.99!

Re: [Elecraft] K3 RX AGC right after a transmission
Hello Arie! ... We SUSPECT that the AGC was still at the level from BEFORE the transmission. Yes, AGC is suspended during transmission, then resumes during receive. The assumption is that the band hasn't changed that much in the milliseconds (CW QSK) to several seconds (SSB voice). ...the work around was setting the AGC to fast. In general, fast AGC is most often used for CW and slow AGC for voice or data operation. 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: so just who owns a K3?
I first met Dave Sumner not long after I joined ARRL as a W1AW operator right out of college in 1972. One day this guy came over to the station to operate the contest after the code practice transmission was over. He looked to be maybe 17. He said his name was Dave and he worked as an Assistant Secretary over in the main ARRL HQ building. I didn't know what an Assistant Secretary was but I figured he must be some local high school student who came in after school to help out the secretaries. He was a good operator though. As the last of the code practice transmission ended, he leaned over my shoulder and made three CW QSOs before I could even finish writing the time in the log and get up out of the chair. I was also impressed that he could send CW with one hand while simultaneously writing in the log with the other. (He's left-handed as I recall.) I later found out that he was actually a year older than I. I also learned that an Assistant Secretary was not someone who helped the secretaries sort paper clips, but rather a fairly high-level position in the administration. He always seemed a high-energy kind of guy, extremely enthusiastic about ham radio. It's nice to see he hasn't gotten jaded over the years.
