Re: [Elecraft] K3S - have initial shipments begun?
What's the best way to check on the status of a previously placed order? Specifically, I ordered a new K3S about 6 weeks ago via internet and have not received any sort of confirmation. I'm suspecting I may have screwed up the order and it never went through (gasp!) I know they're are really busy, so I don't want to add to the confusion by pestering, but I AM getting a little concerned. 73, Charlie k3ICH __ 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

Great, Gerald. Glad it was an easy fix and many thanks for sharing the solution with all of us.

The radio was shipped back to me after a trip to the factory for an upgrade and repair. The radio came back and once it was hooked up, I joined a group of people that I talk to all the time. Everyone said that my audio did not sound right. The intermittently it would go from just okay to terrible. I had one of the guys I talk with watch me on his pan adaptor and it showed spikes and a very dirty signal. I contacted Elecraft by e-mail on the weekend and first thing Monday Morning Howard from Elecraft had called me and left message for me to return his call. I returned his call and he walked me though all of my settings. Then after everything checked out he said that he had see something similar to this and explained what he thought it might be. Howard told me that if I removed the fans and circuit breaker panel off of the back side I would be able to see where the amp connected in. Howard e-mailed me two pictures one the correct way and the other was one they had found the caused a similar problem. I pulled the plate off of my radio and sure enough the amplifier was not seated all the way down in the connector. I pushed down on the amp board and it seated completely with the connecting board. I then loosened all the screws on both the board and the amp and made sure they were seated and then retightened the screws. My K3 is now functioning great. I don't know how it came loose, but it did. It could have been loosened and moved during shipping, I do not know. I took a picture of the connector before I secured it, but I do not know how to post a picture of it here. Okay hope this answers everyone's questions and hopefully if someone ever has these symptoms and research the forum they will be helped by this too.

[Elecraft] CW filter and Roofing filter
Trying to sort this out... 1) with any filter selected using the XFIL button on the K3, there is only ONE crystal IF filter in the signal path. In other words, there is no cascading or tail ending of the filters before and after the IF. 2) if I select a 400 Hz filter with the XFIL button then adjusting the DSP WIDTH control to any WIDER than 500 Hz is pointless. 3) can the DSP be bypassed to produce a purely analog demodulated audio to the speaker?

Re: [Elecraft] CW filter and Roofing filter
Cascading: The only cascading filtering is first the xtal filter and then the DSP filter. (So there's only one xtal filter) 400Hz-500Hz: Yes listening to a wider DSP filter than Xtal filter is pointless. Although (if configured correctly) the K3 will switch to a wider Xtal filter (if there is one) if you widen up the DSP. Analog demodulation: Demodulation in the K3 is DSP.

Re: [Elecraft] CW filter and Roofing filter
Gee, The K3 DSP cannot be bypassed, it is part and parcel of the K3. The DSP mathematical computations are what does the modulation, demodulation, and forms the filters as well as doing a lot of other tasks. The K3 DSP processing in the K3 is done at a frequency of 15kHz. There is no parallel to an analog receiver. The front end of the K3 is analog, but as soon as the signal is converted to 15kHz, it goes through an ADC and becomes 'mathematical soup' - after processing, the math result is fed to a DAC where it emerges as audio. In other words, the K3 is an SDR with an analog front end and a built-in processor. The K3 must have the 2.7 or 2.8kHz filter installed. If you have additional hardware filters installed, they are not cascaded - BUT the roofing filter can cascade with the DSP filter. Even if you select a narrow filter with the XFIL button, if you widen the DSP bandwidth beyond the width of that narrow filter, the K3 will switch to a wider filter. I hope that helps your understanding. 73, Don W3FPR On 6/24/2015 8:55 AM, Gee wrote: Trying to sort this out... 1) with any filter selected using the XFIL button on the K3, there is only ONE crystal IF filter in the signal path.

No. Once the 15 KHz 2nd IF becomes number soup in the DSP, there are only two analog things left in the chain: The AF amplifier and you. The DSP contains a lot more than just adjustable filtering, such as AGC and demodulation.

[Elecraft] KBPF3 upgrade kit and instructions now available
Hi all, The long-promised KBPF3 modification kit is now available. It applies to the KBPF3, K3 RF board, and optionally to the KRX3 sub receiver. It allows the K3 or K3S to receive signals in the 100-500 kHz range with good sensitivity. This is an interesting part of the spectrum, with For full details on the mod kit, see: http://www.elecraft.com/order_form_parts.htm#K3%20Parts Also see below for an excerpt from my original posting about signals in the 100-500 kHz range. 73, Wayne N6KR * * * In honor of the FCC's proposed 2200 meter allocation (137 kHz), we decided to see if we could improve the K3's receive sensitivity in the 100-500 kHz range. This extended coverage is made possible by the new synth (KSYN3A). After a lot of digging, we discovered the cause of the wide-band low-frequency noise. We also found a way to shift the passband of the KBPF3 lower. With a couple of simple modifications, the MDS (minimum discernible signal) can be improved by about 25 dB at the low end (100 kHz). Here are some test results (preamp off, 400-Hz bandwidth): 137 kHz -114 dBm FCC's proposed 2200 meter band 160 kHz -117 dBm low end of the Low-Fer band 250 kHz -126 dBm test frequency in the long-wave beacon band 472 kHz -133 dBm 630 meter experimental band This represents an improvement throughout the range, but especially at the low end. I believe -114 dBm MDS should suffice at 137 kHz, given the high band noise in this range. Another indication of how well the mods work: With no antenna connoted, the K3's S-meter now just barely flickers (S1) at 100 kHz. Without the mods, the no-antenna S-meter reading could be as high as S7 due to the noise source we've now identified (a voltage regulator). (By the way, this regulator noise had no impact on frequencies about about 500 kHz.) ... __ 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

[Elecraft] [K3] ideas for re-purposing our old K3 synthesizers
I printed out the schematic of the original K3 synthesizer module. The diagram says 'rev. A4' and is dated 8 Jan 2010. Hope that's close to the as-built! (probably is) This gizmo appears to have an output range from 8.7 to 46 MHz. I don't know how much sauce it can develop but I have to imagine +10 dBm or so into 50 ohms, I bet it's flat across that range, and it looks like the thing would be whistle-clean. To get that, it needs a tight 49.38 MHz reference oscillator (I found a 0.5PPM TCXO for ~$30 from mainland China), and several common DC supply voltages. It also needs a small microcontroller or other way of providing the correct serial peripheral interface command lines and interaction. That processor would also control the output frequency, perhaps with an encoder, or whatever human interface might make sense. But first, I am trying to see if developing a 'host' PCB would even be fiscally wise to design and construct. I mean, who needs a 8.7 to 46 MHz VFO? And, how mad would Eric or Wayne be with me about the ... um ... semi-inverse engineering research ... I'd have to do to make this thing operate? On the other hand, I wager there's a thousand-plus of these modules sitting around the planet looking for something to do. The capitalist in me is intrigued. So, a bit of market investigation here: a) what would you do with such a device if you had one? bench signal generator? beacon transmitter? VFO for another radio? b) would you pay, say, $100 for a host board to operate your now-surplus synthesizer? c) if someone *else *needed YOUR spare module for THEIR project, what would you be willing to sell it to them for? Free? $25? More? 73 es tnx Steve KZ1X/4 kz1x at yahoo . 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 Message delivered to arch...@mail-archive.com

Here are some test results (preamp off, 400-Hz bandwidth): 137 kHz -114 dBm FCC's proposed 2200 meter band 160 kHz -117 dBm low end of the Low-Fer band 250 kHz -126 dBm test frequency in the long-wave beacon band 472 kHz -133 dBm 630 meter experimental band This represents an improvement throughout the range, but especially at the low end. I believe -114 dBm MDS should suffice at 137 kHz, given the high band noise in this range. Another indication of how well the mods work: With no antenna connoted, the K3's S-meter now just barely flickers (S1) at 100 kHz. Without the mods, the no-antenna S-meter reading could be as high as S7 due to the noise source we've now identified (a voltage regulator). (By the way, this regulator noise had no impact on frequencies about about 500 kHz.) ... __ 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 li...@subich.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 Message delivered to arch...@mail-archive.com

[Elecraft] [K3] ideas for re-purposing our old K3 synthesizers
Well, USD25 for the old synthesizers is good enough for me and I will be happy to sell it. However, I cannot think of any interesting project for it. 73 Johnny VR2XMC 寄件人︰ inventor61 . invento...@gmail.com 收件人︰ elecraft@mailman.qth.net 傳送日期︰ 2015年06月25日 (週四) 10:18 AM 主題︰ [Elecraft] [K3] ideas for re-purposing our old K3 synthesizers I printed out the schematic of the original K3 synthesizer module. The diagram says 'rev. A4' and is dated 8 Jan 2010. Hope that's close to the as-built! (probably is) This gizmo appears to have an output range from 8.7 to 46 MHz. I don't know how much sauce it can develop but I have to imagine +10 dBm or so into 50 ohms, I bet it's flat across that range, and it looks like the thing would be whistle-clean. To get that, it needs a tight 49.38 MHz reference oscillator (I found a 0.5PPM TCXO for ~$30 from mainland China), and several common DC supply voltages. It also needs a small microcontroller or other way of providing the correct serial peripheral interface command lines and interaction. That processor would also control the output frequency, perhaps with an encoder, or whatever human interface might make sense. But first, I am trying to see if developing a 'host' PCB would even be fiscally wise to design and construct. I mean, who needs a 8.7 to 46 MHz VFO? And, how mad would Eric or Wayne be with me about the ... um ... semi-inverse engineering research ... I'd have to do to make this thing operate? On the other hand, I wager there's a thousand-plus of these modules sitting around the planet looking for something to do. The capitalist in me is intrigued. So, a bit of market investigation here: a) what would you do with such a device if you had one? bench signal generator? beacon transmitter? VFO for another radio? b) would you pay, say, $100 for a host board to operate your now-surplus synthesizer? c) if someone *else *needed YOUR spare module for THEIR project, what would you be willing to sell it to them for? Free? $25? More? 73 es tnx Steve KZ1X/4 kz1x at yahoo . 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] [K3] ideas for re-purposing our old K3 synthesizers
Hi Steve, Not to throw cold water on this, but the original KSYN3 requires a ton of firmware support, including a hand-tweaked table of thousands of PLL divider values pre-calculated and stored in flash memory. We shoehorn the DDS reference signal through a 3-kHz wide crystal filter in order to ensure no close-in spurs, then adjust the PLL divider values in real time so there are no gaps in the tuning range despite a nominal 20-kHz PLL step size. Lots of idiosyncratic math, and a critical calibration step (VCO CAL). So if each of your repurposed KSYN3s comes with a K3 front panel MCU and flash, no problem :) 73, Wayne N6KR On Jun 24, 2015, at 7:18 PM, inventor61 . invento...@gmail.com wrote: I printed out the schematic of the original K3 synthesizer module.

Re: [Elecraft] K3 Reports of intermit bad audio
And what was the reason of your bad audio? That might be even more interesting for some readers ... ;-) 73, Olli Contest, DX radio projects: http://www.dh8bqa.de Am 24.06.2015 um 03:47 schrieb KC6CNN: I am happy to report that my awesome audio is back. Thank you Howard, Wayne, and Eric for your outstanding customer service. All is great with my K3 now. It still amazes me and it floored a couple of other hams that were here in my shack when Wayne returned my e-mail. They were like That is one of the owners, I was like yeah. They could not believe that a simple guy like me could get one of the owners to e-mail me back. I laughed and told them that I had exchanged e-mails with both owners and had even spoken to them on the phone. One of the hams laughed and said yeah try that with any of the big three. Then said he believed he was going to sell his radio and purchase a new K3. I explained the new K3s to him and told him he would not miss the old radio. Got off subject here sorry.
