Re: [Elecraft] K2 noise on receiver when switching from transmit
Mike, With the blue toroids, you do have the updated KPA100. Can I assume that this problem is a recent occurrence rather than a problem that has always been there? Yes, removing and jumpering out the KDSP2 will likely stop it (or just try putting it in bypass), but that is not the source of the real problem, it is just the source of the 'pop'. I would suggest digging into the KPA100 a bit. Lay the KPA100 on its 'back' on a book or box to the right of the K2, remove the shield and make the diode voltage measurements. Hopefully that will reveal an anomaly. 73, Don W3FPR On 6/10/2015 12:45 AM, Mike Fanning wrote: Thanks for the quick reply Don! I checked the 8R setting and it was indeed set to hold (and is set there again after toggling it to make sure). I do have the KDSP2 option with the KPA100, but after peeling off the right side panel I see two baby blue toroids. The K2 is serial number is 5882 and it was purchased in December 2006. The KPA100 was bought at Dayton in 2009. I think it took me another year to get around to building it, so it was probably buttoned up about 5 years ago and has been the backup/receive only rig since doing all the alignment checks. This will be the first time I have really done any transmitting with it since adding the KPA100 (I’ll make sure to revisit the PA screws as instructed). You have given me something else to check though - I need to pull the KDSP2 and see if that affects the problem. I’m wondering if there were other upgrades to either the K2 or KDSP2 that might affect this as well? __ 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 Message delivered to arch...@mail-archive.com

It eventually just gave up and displayed that DS5. The other issue is that the power and SWR meter while transmitting dont move or update after a few second or dont update at all while on SSB. This has been happening for a while. I've tried resetting it, but after EEINIT message it still displays my banner and it feels like it hasnt reset everything, I've also restored the settings, but the power and SWR meter still dont show. I would like some help on this to fix this issue, what steps can I do to check everything is ok with the transciever, before mailing it out.

Re: [Elecraft] Need local help
The cards I listed yesterday have both mic and line level inputs (separate jacks) one or the other will be a reasonable match for the headphone output. As far as driving the mic input of the KX3 with line (speaker) output, simply put a 10:1 (20 dB) attenuator in the cable to the mic input. Typically one would connect a 1 uF cap to the tip of the speaker jack, a 10K resistor from the cap to another 1 uF cap to the mic input of the KX3 and a 1K resistor from the junction of the 10K resistor/output 1uF cap to the shield/return (from sleeve of the speaker jack to mic return of the K3). Note: the 1uF caps are simply there to block DC on the sound card output (may not be necessary) and block the bias on the KX3 mic line (if the KX3 is configured for use with an electret mic). If the drive is still excessive, change the 1K resistor to 470 Ohms (22:1 or -26 dB). 73, ...

Re: [Elecraft] KX3 - KPA100 communication problem
A fine issue this is, Bernie. Couple of questions: 1) Tell us about the connection to your computer. What type? How are using the computer with the KX3/KPA100/PX3? 2) Have you checked the software settings for the KX3 Utility, the KPA100 Utility and the KX3 Utility? All good there? 3) And just for the heck of it, have you tried swapping KUSB cables in the event one of those may be the culprit? Just my two cents.
