[Elecraft] K3/100 Audio level problem
?Hi , I am getting low audio level from my K3/100. When I turn AF button to full clockwise I am getting nearly the 10% of the normal audio level in that position. I did hard-reset to my K3/100, I reloaded the latest firmware again but nothing changed. All the other functions of my K3/100 seems OK, except the audio level which is to low. What can I do to solve this problem? Can any one help me? In the mean time I found the AF Knob (Concentric Shaft, Small) as broken (I don't know why). 73, Ruchan Ozatay (TA2AH) K3/100 (#1230) ta2a...@superonline.com __ 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] Elecraft Hexkey Question
Stan - I've never used the Mercury or the Hexkey. It's hard to believe Bencher can make a gem of a paddle when their standard paddle (BY-1, etc.) is so poor. My favorites are made by N3ZN and Begali. You might want to take a look at those as well. Mechanically, they are both superb, and design-wise, they use short, low mass arms for the least inertia and quick return. LIke you, I do 95+% CW.

[Elecraft] K3 #3674 needs EE Init after each power OFF/ON
Wonder if anyone else has seen this odd K3 behaviour and may be able to help me solving the following problem. K3 with ATU and KPA K3 loaded with most recent firmware (MCU 4.12, FPF 1.13, DSP1 2.60). I have repeated the firmware download a couple of times, but it did not solve the problem described below. Every time the K3 is powered ON (using the K3 pwr switch) it comes up in unexpected state where - the LCD indicator TX is blinking (as if TX is in test mode) - the TX LED lights red when keying (CW) - there is no sidetone when keying - the power indicates 0 and there is no output (verified on sep. RX) Restoring saved K3 config. doesn't help. But.. When leaving the K3 powered ON but just idling for a long time, it can be keyed again. After 15 mins it still is in the strange state but after 30 mins it is normal again. Whenever it is in this state with blinking LCD TX indicator it can be recovered performing the EE INIT (Manual p.65), upon which the TX led stops blinking and the K3 can be keyed again. It just needs the proper saved K3 config file - and it's a tedious way to start-up the rig ;-) OZ4UN Poul-Erik __ 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

The radio is receiving and transmitting fine but cannot make any panel adjustments. Power supply is good under load I downloaded the latest firmware successfully but and even uploaded my latest saved configuration file but to no avail. I even tried to do the Parameter reset listed on page 63 of the manual (with power off, hold down SHIFT/LO knob then power up) but nothing is helping.

Re: [Elecraft] P3 and continuous 5-15 db 'spike'
The LO leakage of LP-PANs after serial number 200 is about -120dBm. Earlier serial numbers had a bit more leakage, but this is easily fixed by changing the value of C40 to 0.001uF. -120dBm is overkill for LP-PAN's intended purpose, but connecting LP-PAN directly to a receiver (P3) tuned to the LO frequency changes things a bit. I have run some tests to simulate this situation. First, I connected an LP-PAN directly to a receiver tuned to the LP-PAN LO frequency (8.209MHz for most units, 8.215MHz for the first couple runs). I verified that the leakage was in the -120dBm range by comparing the received signal to my calibrated HP signal generator. Then, I connected the second receiver, LP-PAN and K3 together using a 3dB hybrid splitter . This is reportedly what the P3 uses to split the K3 IF signal. I could detect nothing on the second receiver at the LP-PAN LO frequency. This makes sense since the hybrid splitter has an isolation spec of -25dB between output ports, which should provide an LP-PAN signal of about -145dBm at the receiver input. If you make the change to C40 and if the hybrid in the P3 is working as mine does, you should see nothing from the LP-PAN. I repeated the test using a couple different LP-PANs, and I also tried a couple different models of Mini-Circuits splitters. The results were consistent. BTW, the LP-PAN preamp kit adds another 15-20dB of LO isolation, and lowers the LP-PAN NF to 7dB to help offset the additional loss of the splitter in the P3. 73, Larry N8LP VE3NFK wrote: Yes, Alan an LP-Pan and yes that is where the spike comes from...

[Elecraft] K3 filter centering different behaviour from band to band
Hi you all! I own a k3 since 3 days so probably what I'm writing should be a stupid question, sorry for this. It happens that in 20m band I can center (or better shift) filter from 400 Hz to 4000 Hz, in 15m and in 10m I can only between 1100 Hz to 4000 Hz. I'm sure I did some mistakes during these days playing because I think I'd expect same behaviour in any band isn't it ? but I can't find a way to properly correct my mistake and rollback.

[Elecraft] Use of PC power supplies with K2
I would like to hear from anyone who has attempted to use one of the small external PC AC adapter power supplies with a K2. They are, of course, switchers, so I am not very hopeful. I have found a couple of possible candidates, one a Meanwell P40A-4PSJ rated at 13.8 volts at 2.66 amps and the other an APS AD-740U-1138, rated at 13.8 volts at 2.8 amps. They seem to have somewhat comparable specs as to regulation, ripple, and protection. I suspect they would be pretty bad on RFI, so even though they can be had cheaply, they may not be worth the grief. My fallback position would likely be the little unit from Gamma Research, HPS-1a, but that will be twice as heavy and probably ten times more expensivebut from what I've read about it, it is not very noisy electrically. I would really appreciate any thoughts, especially those with first hand experience. This would only be for portable operation, not normal use.

Re: [Elecraft] Use of PC power supplies with K2
Ken... The general subject of RFI/switching power supplies has been bruited about on this list server several times. I personally have had excellent experience with the several that I use. These include a 20 amp, 13.8 V supply from pyramid and two 25 amp, 13.8 volt supplies from Radio Shack. These supplies sit within inches of my K3/100 and my ICOM 910H and cause no interference that I can detect. On the other hand, I have a circline fluorescent lamp with a magnifier that I transplanted from my workbench to my operating site, about which I made the following discovery. The lamp itself runs off a power supply at the base of the tensor arms. Turning the lamp on and off produces no change in interference, but unplugging the lamp from the wall outlet reduces hash noise on 20 meters by about 3 S units !!!. The wall-wart-like power supply in the base of this lamp is very noisy, and the lamp has accordingly been banished to a less sensitive site. My summary comment would be that power supplies run the gamut wrt RFI problems, and that one might well have to proceed by trial-and-error. I have always rejected use of the PC-type power supply because they usually come with a spaghetti of different wires intended for different functions within the computer. The small Radio Shack 25 amp supplies are about the same volume as a typical PC supply, and a great deal more congenial (cosmetically) than the latter.

[Elecraft] K3's 2-m module (K144XV): Need testers for major performance improvement
Hi all, We've just made a change to the K144XV firmware that dramatically reduces the incidence of weak receive spurs within the 2-meter band. Some of our customers who use SSB/CW on 2 meters had pointed these out, and we traced them to the K144XV's microcontroller (MCU). We now turn the MCU's crystal oscillator off during receive, letting the MCU sleep until you key the rig, change bands, or cross the 144/146 MHz boundary. It's working perfectly in our tests. If you're using the K144XV for SSB/CW and would be interested in trying the new firmware, please email me directly (n6kr at elecraft dot com). 73, Wayne N6KR __ 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

Giorgio, Check your data mode for those bands, and if AFSK A, check the mark frequency. What you describe is normal when set to AFSK A with the mark frequency set to 2125 Hz. This is a per band setting, so yes you could have 20 meters set one way and another way for 15m and 10m. 73, Don W3FPR On 10/3/2010 3:26 PM, ik1bxn wrote: Hi Dave, thanks for quick response.

[Elecraft] K3: DRM
Having been tuning around 6MHz and enjoying greatly the P3, I rediscovered the existence of DRM. I read some time ago that DRM was dead in the water, but notwithstanding, there does seem to be a significant number of stations out there broadcasting. Susan mentioned this sometime ago I believe, and I don't believe I've seen an answer from Elecraft. Is DRM possible within the SDR of the K3? Or do we have to take the IF output and down convert?

Re: [Elecraft] K3 filter centering different behaviour from band to
There are four different data sub-modes on the K3 (selectable by holding the AFX/DATA MD button). Do you have the same data sub-mode selected on all three bands? The default filter center frequency in DATA A is 1500 Hz, which is consistent with what you are reporting on 20m. The default center frequency in AFSK A is 2210 Hz if the Pitch is set to 2125 Hz, and that would seem to correspond with what you are seeing on 15m and 10m. It is also possible that your software is interfering, for example by forcing the filter frequency to a pre-defined setting depending on the mode and sub-mode. You can test this by configuring the software's radio control port to a non-existent port so that the software does not have CAT control, and then adjusting the radio's controls to see what happens. 73, Rich VE3KI IK1BXN wrote: Sorry I forgot telling it happens in Data Mode. 73 de Giorgio __ 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

They are, of course, switchers, so I am not very hopeful. I have found a couple of possible candidates, one a Meanwell P40A-4PSJ rated at 13.8 volts at 2.66 amps and the other an APS AD-740U-1138, rated at 13.8 volts at 2.8 amps. They seem to have somewhat comparable specs as to regulation, ripple, and protection. I suspect they would be pretty bad on RFI, so even though they can be had cheaply, they may not be worth the grief. My fallback position would likely be the little unit from Gamma Research, HPS-1a, but that will be twice as heavy and probably ten times more expensivebut from what I've read about it, it is not very noisy electrically. I would really appreciate any thoughts, especially those with first hand experience. This would only be for portable operation, not normal use.

[Elecraft] K3 - Receiver noise, no antenna?
Hi, I'm recently rec'd my K3 and am very happy with it. However, I am wondering what level noise is normal for just the receiver sitting with no antenna, RF gain at 3:00, Audio gain at 9:00 and the S meter calibrated and set to Absolute? The readings I get are: BandNor ATT PRE 160 S3S5S1 75 S3S5S1 60 S3S5S1 40 S4S5S1 20 S4S5S1 15 S4S5S1 12 S4S5S1 10 S4S5S1 6 S4S5S1 I also noted that even tho I set the SMTR to ABS, it actually showed opposite on the S Meter, but with the Preamp on, the hiss did change to slightly louder, very little change with the ATT. I also noted a slight lower hiss level (audible) when turning the AGC OFF. Above readings were taken with the AGC ON slow. Is this normal, or is there something I can do?

[Elecraft] OT: HexKey
Reference has been made to the spongy feel of the HexKey, and I used to agree. IMHO I'm a pretty good CW op with 60+ years behind me. Even made a living at sea with CW. I was -very- disappointed with my HexKey and was about to put it on eBay. Couldn't seem to send error- free CW and at attributed it to my old poop's arthritis. After pondering awhile and watching intently to see what I might be doing wrong, I realized that the HexKey was moving ever-so-slightly. Simply put, it was wobbling on it's soft feet. I changed the feet to ones made from firmer material and now the HexKey is great. The firmer feet cured the problem. 73!

[Elecraft] K3 Filter Choices
Hi Guys, in my quest to purchase a new K3 I am worndering about 8 pole filter choices. I see that there is a 1.8 KHZ 8 pole ssb filter and a 250 HZ 8 pole cw filter that is avaiable. If one purchases one of these filters wouldn't that basically solve the problem of not needing all the other filters at different KHZ? This probably is a stupid question, but would really like to learn.

Re: [Elecraft] K3 Filter Choices
Hi Mark, You'll need, at minimum, a 2.7 or 2.8 KHz filter for use in transmit. Either one is fine, and they both work quite well. This is the basic roofing filter used on receive as well. If you operate primarily SSB, the 2.7/2.8 roofing filter is usually enough. If you're into contesting, I'd suggest 1.8 or 2.1 KHz as well. For CW and data modes, a smaller width filter might be helpful. I have found that the 1KHz and 250 Hz filters are a good complementary pair for CW and data modes like PSK31. If you only operate CW, any filter at or under 500 Hz is fine. AM and FM modes require wider filters (6 KHz and 15 KHz, respectively) and this is detailed out on the Elecraft K3's web page. A nice basic configuration would be 2.8 KHz for SSB and 500 Hz for CW. You can always add to this since there are five roofing filter positions. 73, matt W6NIA K3 #24, P3 #14 On Sun, 03 Oct 2010 18:27:50 -0500 (CDT), you wrote: Hi Guys, in my quest to purchase a new K3 I am worndering about 8 pole filter choices.

Re: [Elecraft] K3 Filter Choices
Mark, This question is asked over and over, and you will get answers all over the board. The real answer is that a lot of your filter choices will depend on what kind of operating you will do and in what modes. If you do a lot of contesting or work DX in heavy pileups where there are a lot of strong stations close to what you want to hear. then you should have only the 8 pole filters, their skirts are a little bit steeper - BUT - these are only roofing filters, the DSP takes care of most of the filtering, and does it quite well. If you will be adding the KRX3, the filters must be matched for diversity reception, so the simple way is just to use the 2.8 kHz filters. In fact, the DSP filtering is good enough to be used alone, it goes down to 50 Hz width - but the DSP can only do its job if the ADC is not being overdriven - the hardware AGC does protect from that, but will result in pumping of that hardware AGC if there a quite strong (S-9 +20 or more) nearby signals. The K3 roofing filters will knock down the strength of those nearby signals to a point where the hardware AGC is not activated. Eric Swartz has posted some information for making filter choices on the Elecraft website, I suggest you read that too. Bottom line is that you will have to review the type of operating that you will do with the K3 and select your filters from that information. If your operation is rather casual, you may only need the stock 2.7 kHz filter. If you want to transmit either AM or ESSB or you want wide bandwidth SWL reception, you will need the 6 kHz filter, and if you want to either transmit or receive FM, you will need the 13 kHz filter. Another option is to wait and see - order your K3 with the stock filter (or perhaps the optional 2.8 8 pole filter), and operate for a while to determine your usual DSP-set bandwidths for each mode you use - that information will reveal the filters that you will derive most benefit from. A word of caution on my above suggestion - if you will install the KRX3 immediately, you must remove it to add more filters, and that operation has been referred to as a shoehorn operation, so your choice is to guess at the filters needed and order them up front or delay the installation of the KRX3. Without the KRX3 installed, the filters are a breeze to change. 73, Don W3FPR On 10/3/2010 7:27 PM, pastor...@verizon.net wrote: Hi Guys, in my quest to purchase a new K3 I am worndering about 8 pole filter choices.

[Elecraft] Elecraft HexKey Question
Thank you to everyone who responded with such enthusiasm and practical advice. If there's anything in our hobby that is truly personal its got to be a CW op's choice of key. Asking anyone else for an opinion is darn near futile except that when the person asking gets enough feedback, he or she is in a much stronger position to evaluate the range of responses, most often repeated critical issues (pro or con), and then combine that feedbackwith personal research and then...make a choice. I chose the N3ZN ZN-SLR. Ordered it today. Got it with a double thickness fingerpiece. Delivery in two weeks!

Re: [Elecraft] K3 Filter Choices
I have the 1.8 and find it to be a great all round SSB filter, although some contesters are opting for the Inrad 1.5 instead.The 250 is a must for CW, RTTY, PSK, etc..There are also 500 and 700 hz 8 pole filters around for more casual CW or the wider data modes. Haven't heard anyone say anything positive about the 1.0 kc filter. The 6kc is needed if you are interested in AM, ESSB, or SWL. The 2.8 presumably produces a technically better TX signal than the stock 2.7 but so far I haven't been able to justify the expense. 73 Jack KZ5A K3 #4165 On 10/3/2010 7:37 PM, Don Wilhelm wrote: Sam, You tell falsehoods to the K3 when you configure the filter.
