[Elecraft] Oddly behaving K3
Good Morning All, Have gained an odd issue this morning. Rig is serial number 464 and has been flawless since the day I got it. Last night was on 40M CW DXing, all was well. This morning got into the shack (rig is always left on) and I went to change the band from 40m to 20m. I pressed the BAND button and nothing happens. I try the MODE button and again nothing happens. I can tune the main VFO just fine but then I hit the ANT button and that activated Noise Reduction (NR), I press CWT and that toggles CMP/PWR, I press RX ANT and that turns on the Noise Blanker, ATU TUNE toggles the AGC settings, you get the idea. It seems the button mappings are all corrupted. OK things that I have tried: 1. Power cycled the Rig - no change. 2. I was running FW 3.30 and I downgraded to 2.67 (tried this process twice) - no change 3. I then figured it was a hardware issue (loose board) so I tried software controlling the rig with K3EZ and still no good, I can't change bands via software! 4. I pulled the power plug from the K3 and let it sit then powered back on. - no change 5. I then tested my voltage on my power supply (Astron 50Amp) 13.8 6. I have done a reset holding the SHIFT/LO while powering up but in my case its the SPOT button that does that function. After a reset still no good. I think I have exhausted all that I can try at this point. Anyone have any suggestions before I call Elecraft? Thanks and 73, Lee -WW2DX __ 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
[Elecraft] Yamahs CM500 Headset

Several of the guys in our contest club have bought these headsets and fired them up with their K3s. One of them, W6XU, brought one to our meeting last night, and I tried it on.

The mic is a cardioid electret. Another of the guys, K6TD, had me listen to his on the air. It sounded very good with no tweaking of the K3, and with tweaking, produced very competitive audio. The tweaking consisted of using maximum cut on the three lowest filters, 6dB boost at 2.4 kHz, and 10 dB boost at 3.2 kHz. I also had him kick in about 10dB of processing. This eq is consistent with most mics designed for SSB communications use (like the Shure and Heil products). The difference is that this headset sells for only $45 online at Sam Ash with free shipping, a bit more at other vendors.

Re: [Elecraft] K3 PowerPoint presentation
Hi Bill, Actually, this does apply to diversity RX. I have listened on 80M and 40m using two antennas, with different orientation and arrival angle optimization, feeding the two K3 receivers, one in each ear. When listening to a round table discussion each person appears to sound like they are coming from a different direction in 'the room'. Listening to pileups is really interesting for the same reason. I can frequently pick out signals spatially using diversity RX that would normally be buried in the pile up cacophony. :-) 73, Eric WA6HHQ Bill Tippett wrote: G4DMP: I am very impressed by the new PowerPoint presentation available at http://www.elecraft.com/manual/K3%20High%20Performance%20%20Design%202009%20w_P3%20pub.ppthttp://www.elecraft.com/manual/K3%20High%20Performance%20%20Design%202009%20w_P3%20pub.ppt The only point that struck me as odd was the following on Slide 6 under Dual Diversity RX: Pile-ups / QRM spread out spatially.

I was thinking of the CW spatial effect with Binaural AFX having high pitch on one side and low pitch the other side. Using diversity for DX signals, I find they often shift between one ear and the other as the signal changes. The net result it that you can copy a signal continuously that might be fading in and out if you were using only one antenna. I love diversity and use it 99.9% of the time I operate!

Re: [Elecraft] K3 PowerPoint presentation
Hi Dave, These are my slides, used from several past hamfest presentations. I certainly wasn't trying to hide behind anything. They were made available on the web site this morning at the request of several customers. The only reason the general price of several other radios were noted in the performance comparison table was to highlight how well the K3 receiver does in comparison, especially against the $10K plus radios. Even with the P3 panadapter, we'll be well below 1/2 of that. To be honest this is a very minor part of the slide presentation and I'll be glad to remove the price info if people wish. Except for the 7600, which has only been tested by Sherwood so far, all of the RX numbers in the table are from published ARRL reviews. Sherwood's numbers and those from the ARRL are usually in agreement within a couple of dB for these tests. 73, Eric WA6HHQ --- Dave-Boat Guy wrote: This presentation is interesting and informative.

Re: [Elecraft] Power point
It would be nice to explicitly give the bandwidth associated with the dynamic range numbers. Most tests I have seen use 500 Hz but. In any case one assumes that all those numbers are obtained with the same bandwidth, or at least normalized to a specific bandwidth. Without a statement of bandwidth this is just an assumption. ARRL, RSGB (RadCom), W8JI and Sherwood always use 500 Hz or the Closest Available to 500 Hz (per ARRL Test Procedure). Sherwood is the only tester who sometimes uses additional bandwidths but they are always footnoted. 73, Bill W4ZV __ 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
Re: [Elecraft] K3 PowerPoint presentation
Dave Boat-Guy wrote: From my calculations, a K3 WITHOUT a band-scope or panadapter or spectrum display that is built up so that it is comparable in basic features to the Ten Tec Orion or ICOM 7800 or Yaesu FT9000 (which has a model that is significantly less than $10K), is pushing $4000. Any method you use to to add a spectrum display will push it over that in a hurry. I like to see honest advertising but one has to wonder about this sort of comparison. One of the benefits of a modular approach like the K3 is that I'm not forced to pay for features I don't want or need. This includes stuff like AM, FM, General Coverage, ATU, etc. Why should I load up my $3000 Dual Diversity K3 with features I don't need for a valid comparison? The problem with the approach of most other rigs is that I cannot delete features I don't want. IMHO this is their problem and one of the key reasons the K3 is such a good value if you use a little care in configuring it. 73, Bill W4ZV __ 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
[Elecraft] dynamic range bandwidth
ARRL, RSGB (RadCom), W8JI and Sherwood always use 500 Hz or the Closest Available to 500 Hz (per ARRL Test Procedure). Sherwood is the only tester who sometimes uses additional bandwidths but they are always footnoted. 73, Bill W4ZV I understand that, because I pore over others test data to compare my own receiver work with the professionals. And I know the difference in dynamic range between 400 Hz and 500 Hz is very, very small. But in a comparison of different receivers the test bandwidth should, in my opinion, be included in the comparative data to nail it down. If I was giving a talk at my local ham club, I could measure the K3 MDS with the DSP bandwidth at 50 Hz and make the K3 sensitivity and dynamic range look even better. But...of course that would be a little deceitful, eh? IMHO the viewer should not have to go to the Sherwood test and the ARRL test to verify the dynamic range is for the same bandwidth. All it takes is a statement of the bandwidth and the basis for the data is fully defined without having to go back to original sources and figuring it out for yourself: a significant level of trust is instantly established in the data. No games need to be played for the K3 to look good and I'd hedge my position by explicitly stating the comparative bandwidths.

[Elecraft] K3 Diversity RX
My K3 includes the KRX3, KAT3 KXV3A. On 160m and 80m, I use a shunt fed tower for TX/RX and a separate RX loop that goes through an RF limiter and external preamp to RX ANT IN. For Diversity RX, the loop has to be connected to AUX RF but it's then not available to the Main RX. In order to have the flexibility to use the RX loop with either the Main RX or the Sub RX for diversity, I built a switch box to route the loop to either RX ANT IN or AUX RF. A HOLD of the K3's RX ANT button toggles the antenna input to the Sub RX to the correct BNC. I considered using ANT2 on the KAT3 but it wasn't obvious that I could achieve the same flexibility. Other solutions to allow the RX loop to be available for both the Main RX or the Sub RX in diversity mode? My tower and RX loop are very close. The RF limiter protects the RX front ends from QRO. Caution! Your situation may be different. While in diversity RX you can operate split and also check your TX frequency with the REV button. Then use VFO A to find your spot. A very elegant design feature! 73 - Steve WB6RSE __ 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
[Elecraft] K3 Serial Number 3430 is up and running
The K3 # 3430 build went well and the K3 is on the air tonight. This is the 3rd K3 I have assembled and It was again a pleasure to build. The fit of all the hardware is still impressive. The ERR messages are very helpful and always point to the correct action needed. The K3 is still a pleasure to use. I can't wait for the P3. That will complete the K3 very nicely. 73's Ron Durie WB4OOA Elecraft K3/100 # 604 __ 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
[Elecraft] K3 MDS calculations using the Elecraft XG2
I set up the K3 Rx sensitivity test (using 1 microvolt signal) according to XG2 manual. It seems to work in general except that the resulting MDS calculations seem too low: 123 dBm on 80 meters, 132 dBm on 40 meters, and 130 dBm on 20 meters. I am using the front headphone jack on the K3, with the CONFIG:SPKR = 1. AGC is off. Preamp is own, RF AF gains are at maximum, and the CW passband is set to 500 Hz. The AC measurements were made using a Craftsman autoranging multimeter. Example: on 40 meters the reading was 0.310 V with XG2 on and 0.018 V with XG2 off. (0.310/0.018) = 17.2. Log 17.2 x 20 = -24.7 dBm. MDS = -107 dBm -24.7 dBm = 131.7 dBm. I was expecting a better value (maybe -137 dBm?) Could it be a problem with the DMM? If so, is there a recommended DMM? Thanks in advance for your help. 73, Fred AE6IC __ 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
Re: [Elecraft] K3 MDS calculations using the Elecraft XG2
Could it be a problem with the DMM? If so, is there a recommended DMM? If using the K3, use the internal RMS audio meter (tap DISP then rotate until you see AFV). 73, Lyle KK7P __ 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
Re: [Elecraft] dynamic range bandwidth
W7AAZ: I understand that, because I pore over others test data to compare my own receiver work with the professionals. And I know the difference in dynamic range between 400 Hz and 500 Hz is very, very small. About 1 dB from Elecraft's own measurements if I recall correctly. But in a comparison of different receivers the test bandwidth should, in my opinion, be included in the comparative data to nail it down. If I was giving a talk at my local ham club, I could measure the K3 MDS with the DSP bandwidth at 50 Hz and make the K3 sensitivity and dynamic range look even better. But...of course that would be a little deceitful, eh? Why? Most testers have adopted ARRL's methodology of 500 Hz BW (or closest filter to that) at 2 kHz spacings. What's deceitful about that? IMHO the viewer should not have to go to the Sherwood test and the ARRL test to verify the dynamic range is for the same bandwidth. All it takes is a statement of the bandwidth and the basis for the data is fully defined without having to go back to original sources and figuring it out for yourself: a significant level of trust is instantly established in the data. No games need to be played for the K3 to look good and I'd hedge my position by explicitly stating the comparative bandwidths. Elecraft used published ARRL measurements at 5 kHz spacings for their Power Point comparison table and ARRL always uses 500 Hz filters (or closest thereto). I don't see any basis for saying games were being played. If the tests were using significantly different BWs (e.g. 200 Hz vs 500 Hz) you would be correct. If you want to see games being played, check out Icom's and Yaesu's claims of 3 kHz roofing filters that are actually 5-6 kHz, or 6 kHz filters that are actually 10 kHz. Elecraft doesn't do stuff like that. 73, Bill W4ZV P.S. Re your comment about the K3 having high power consumption in RX mode a week or so back. The K3 is one of the most power efficient rigs available, especially for a 100W class radio.
