[Elecraft] Weird KIO3UPKT problem
Howdy folks... I've been chasing this problem for a while thinking it was in my audio system.but NO!! I use a laptop computer with an external HIFI audio board. The HIFI audio board drives a very nice amplified JBL speaker system with a subwoofer. The external audio board occupies one USB port on my laptopwhen I plug the KIO3UPKT cord into any of the other 3 USB ports on my laptop I get what sounds like 60 cycle hum out of my HIFI audio system. It doesn't matter which port I plug the HIFI audio interface intoas soon as the KIO3UPKT is plugged in I get the hum. The KIO3UPKT seems to function just fine in all other ways except for inducing this noise. Any ideas???

Re: [Elecraft] What is wrong with my K2 #6705 ??
Don We're thinking alike I think. I've started with the assembly of the KAT2 option. I've still got the KAT2, Batt, SSB, KIO2, and 160M options to build. I'm hoping the installation of the KAT2 will fix my problem. Fred Don Wilhelm wrote: Fred, That dummy load is way off at DC, so who knows what the actual value is at RF. It could be the only source of your problem. Specifically, *any* deviation from 50 ohms pure resistive will cause the basic K2 to indicate (and control) power incorrectly. That dependency is removed when the KAT2 or KPA100 or KAT100 are added because those options contain true wattmeters. I don't have any assistance to offer other than to say find a known good dummy load. Ridge Equipment has a 50 ohm dummy load flat to 1.5 GHz for $11.99, but you will likely need an adapter for the input - they sell those for $5. See https://www.ridgeequipment.com/store/dummyloads.html The base K2 has only a diode detector to measure the RF output, so it can only measure the voltage. Using the 10 watt level as an example, with a 50 ohm load, the K2 measures 22.3 volts of RF and declares that the power is 10 watts (and it actually is). If the load is instead 63 ohms, and you request 10 watts, the K2 will control the power until the RF voltage reaches 22.3 volts, but the actual power being developed is only 7.9 watts. Your dummy load likely has some reactance as well as resistance, so who knows what the actual impedance is at the various frequencies. 73, Don W3FPR Fred Bennett N9TA wrote: Hi Folks I stayed home from work today to do a little work with #6705.

I've no time to troubleshoot the thing tonightbut here's what's going on: Low power out 80M thru 10M (6-7 watts), except on 12 meters where there is NO output!! I've probably missed a solder joint in the 30M section or somethingbut what would be the things to look at for the low power output on ALL the other bands??

If the 8 volt regulator output is on the lower side of its spec (it is a 10% tolerance part), then everything will work out just fine, set it to the maximum. Reason - the IF amplifier is the stage controlled by the AGC, *and* it is powered by the 8 volt regulator. When the IF Amp supply voltage is reduced, the ACG action begins at a lower voltage point than at higher voltages. Bottom line - if you are able to set the S-meter parameters with the lower AGC Threshold voltage, then all is well. If you cannnot adjust the S-meter, then a 10k to 15k resistor soldered across pins 3 and 4 of Control Board RP6 will allow you to adjust the threshold upward. Yes, a manual errata sheet should be published IMHO. The 3.8 volts is not graven in stone. There is an implication in the K2 manual that the AGC threshold can be optimized later on, but there are no details of how to do that - in fact, that optimization is simply reducing the AGC Threshold voltage so that receiver noise does not activate the AGC. 73, Don W3FPR Fred Bennett N9TA wrote: Hi Gang Construction on my 3rd K2 is coming right along..BUTI have a question: I'm at page 48 of the manual where I am going through the first power-up checks.

You *did* transfer all the information in the errata sheet into the manual before you started did you not? If not, that is standard operating practice and very important. I cannot emphasize the importance of the errata sheets enough - they contain the latest information and using that information can avoid many errors.

[Elecraft] My third K2
Hi Gang Well, I took the plungeagain!! My third K2 has been orderedand is nearing my location via UPS. My first K2 was serial number 242 (I think).I think the second was around 4500 (I'm not sure)it'll be interesting to see what serial number they are up to now!! I keep them for a couple of years and then trade them for something else.one of my many faults is always looking for something better...HI HI. I really struggled this time thoughK3 or K2 was the question. In the end I chose lower power consumption for working off battery power. Besides, after watching numerous K2 and K3 videos on YoutubeK2 just seemed like coming home again! 73de...Fred N9TA K2 serial# ? __ 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 filters
I've been wondering how the K3 does on phone. Can someone post some recordings of the K3 receive audio on SSB and perhaps SWLing???

RE: [Elecraft] Sidetone volume
Tnx Don I think you may have hit the nail on the head. I DO have to reduce the volume greatly when using the headphones. From my perusal of the schematic for the K2, it looks like if I changed R36 it would change the AF level on both the speaker AND the phones...NOT what I *think* I want. It looks like R35 (a 82 ohm resister) is in line with the AF feed for the phones. Does this look right?? On Phones I use a sidetone level of 25...on speaker I use a sidetone level of 140is it possible to deduce from this what a good value of resister would be for R35?? TNX for the help!! 73...de...Fred N9TA ___ Fred, Since you are reducing the setting of the AF gain control when changing from headphones to the speaker? If so, that is the reason in a 'nutshell' - the level of the sidetone is not controlled by the AF gain. So, if you set the sidetone level to be correct for your speaker volume, then it will be too loud when you reduce the AF Gain for use with the headphones. I would suggest that you try increasing the value of R35 and R36 on the K2 RF Board so you do not have to reduce the AF Gain as much when using the headphones - or switch to a less sensitive set of headphones. You can also just change the sidetone level in the menu (assigned by default to the PF1 button) when switching from speaker to headphones. 73, Don W3FPR -Original Message- My wife often invades my shack to watch TV while my son plays Xbox on the TV in the living room. I plug in my headphones while she is watching TV so that the noise won't bother her...(and the noise from the TV won't bother ME)...But when she's gone I unplug the headphones and use an external speaker. I have noticed a VAST difference in the sidetone volume between headphones and speaker. I must turn DOWN the volume a BUNCH when using the headphonesbut then when using the external speaker the sidetone is almost completely silent. I adjust the volume for comfortable listening levels with both the headphones and the speaker...but the sidetone volume seems to change between the two. Is there a cure for the difference in sidetone levels?? 73...de...Fred N9TA -- No virus found in this outgoing message. Checked by AVG Free Edition.

[Elecraft] K@ DSP Audio Filter Product Suggestion
Hi Gang Having played with my new DSP gizmo I have come upon the Man, I wish I could idea that would seem easy to carry out. When setting up the audio filters, I would like to be able to select GAIN settings for each filter bandwidth. Right now, there are a possibility of 4 different filter bandwidthsBUT they all share the same Gain setting. If I could have different Gain settings for each filter bandwidth, then I could set up a variable CW PEAKING filter that could have progressively higher Gain for progressively lower bandwidth. This would allow me to take a small slice of the band and amplify the signal for reallyreally weak signals!!! Any possibility??? 73deFred N9TA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] K@ DSP Audio Filter Product Suggestion
Exactly the idea! Surf the band in a higher bandwidth/ lower gain setting, and if you come across a weak signal you want to pop out you go to a progressively lower bandwidth/higher gain Afil. However, if you have to leave the gain at a high setting and you surf thru a load signal, then unpleasant noises may result. :-) -Original Message- This is an interesting idea. A potential problem is that the KDSP2 is not really intended to provide gain in the normal sense of amplification. The gain adjustments are intended solely to to provide equalization, so the apparent insertion loss of the KDSP2 should be about 0 dB. Here's why. The input analog-to-digital converter has a certain maximum voltage that it can accept from the product detector in the K2. The output digital-to-analog converter has the same voltage limit. If you apply too much internal gain in the DSP to a weak signal, and a strong signal comes in, you may overdrive the digital-to-analog converter, resulting in loud and unpleasant distortion. The K2 AGC normally mitigates this by limiting the input signal to the analog-to-digital converter, but some operators turn the AGC off. With the AGC off, the risk of unpleasant acoustic consequences increases! Thus, I recommended setting the gains solely for equalization. As you narrow the DSP, just turn up the AF gain control on the K2 :-) Enjoy! Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Problems with K2 #4502 ??
Hi Gang I just completed my 2nd K2..I sold the first one (#242) a couple of years ago. The new K2 (#4502) was completed this morning. This K2 was built with the KAT2, KIO2, KSB2, K160RX, and KBT2 options. I seem to have rather low power output..at least I remember the last K2 I built seemed to have higher output than this one.might I have a problem somewhere??? I tried the alignment both with and without the ATU installed.so I know the ATU is not the culprit. These power readings were obtained into a dummy load and measured with the same digital wattmeter I used with the last K2. 160M.13 watts 80M.14.13 watts 40M.12.8 watts 30M.13.26 watts 20M.13.1 watts 17M.12.6 watts 15M.11.0 watts 12M.10.4 watts 10M.7.74 watts Also, I may have wasted my money on the battery option. The instructions for the battery option say to charge the battery from a 14V +/- .2V...I run my K2 from a solar charged battery setup. At night with NO sun the system runs about 12.7V. During the day with FULL sun it'll run about 13.7V. I had hoped to be able to grab the K2, key, and portable antenna and head off into the woods for an afternoon of play..but it looks like I'll have to charge the battery from some other source. I kinda hate the thought of that!! So far in it's life, K2 #4502 has had NO commercially produced electrons inside it..seems like blasphemy to plug it in...HI HI Any thoughts, ideas, comments??? 73de...Fred N9TA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
