Re: [Elecraft] K2 Filter settings
Gareth, Since you are using DM780, yes you can see the 100 Hz subcarrier. I usually use the Spectrogram 'scope display and that subcarrier is there but it is a low amplitude and becomes lost in low frequency 'trash' like any 60 Hz noise in the computer soundcard and the zero frequency spur. 73, Don W3FPR On 3/3/2015 2:29 AM, M5KVK - Gareth wrote: Thanks Don Since sending that email, I'd come across Wayne's article on the mechanics of CAL FIL. That opened my eyes to something I'd read, but clearly not absorbed: i.e. when a modified BFO is saved, the K2 re-calculates the value of VCO needed to obtain the same AF tone as before. Although the audio moves moves when the BFO is adjusted, once the BFO is saved, the tone goes back to where it was (or within 20Hz anyway). One thing though. Unless it's just my KSB2 filter, you can still see WWV's 100Hz sub-carrier on DM780 when the filter skirts are set as you suggest.

Once C22 is properly adjusted, put the counter probe in TP1 and run CAL PLL. When CAL PLL finishes, then go to CAL FIL. Even though the FL1 passband has been previously set, you must still change the BFO settings. Move them up one DAC count and back down to where they were before. Then adjust the BFOs for SSB FL2 thru FL4. I set the low frequency slope of FL2 at 350Hz, FL3 at 400Hz, and FL4 at 500Hz. Adjust the BFOs for the CW filters (and RTTY filters if you have them enabled) to properly position the filter passbands. If they were set correctly before, move them by one DAC step and back again - this is to force the BFO frequencies to be recorded into EEPROM with the current 4MHz reference frequency. After those steps, re-check the WWV tuning. It should be correct within 20 Hz. The BFO DAC steps are approximately 20 Hz wide, so you may see a shift in the tuning by that amount.

Re: [Elecraft] K2 Filter settings
Unfortunately the shift in dial calibration between filter settings is due to the limited resolution of the DAC converters that control the BFO. It is a design compromise, not much you can do about it. If you adjust the reference oscillator, eg. by using Wayne’s procedure, then you need to run the CAL PLL and CAL FIL procedures again to update the firmware parameters. So, if you modify the filter settings such as the skirt positions, don’t run Wayne’s process again, or you’ll need to repeat the CAL PLL/CAL FIL procedures. -- 73 de Matt VK2RQ On 3 March 2015 at 3:11:58 am, Gareth - M5KVK (m5...@m5kvk.org) wrote: I realise this is close to becoming an obsession, but I really want to understand what's going on.

[Elecraft] K2 Filter settings
Thrilled to get my K2 working on 7 MHz receive but I seem to have a problem with filter settings. Everything has checked out according to the book - no problems at all (even my home-wound coils seem to work!!) I have set up the filters exactly according to pages 88 and 89. On Filter 1 the rx sounds great - plenty of gain, clean signals. On the other 3 filters it sounds like I am listening through a dense fog - I can tell the bandwidth is far narrower than F1 but signals are weak and it sounds as if the filters are overlapping each other (if you know what I mean). I have checked settings again and all look OK. Does anyone recognise this problem please?

Re: [Elecraft] K2 Filter settings
I'll be the third to chime in on how useful the spectrogram method of aligning filters is. The first time around (without spectogram) I noticed similar results as you did, then I did the spectrogram alignment and it got *much* better, but it still wasn't right. Third time, it got even better. I'll be doing it again this weekend I think, it's somewhat of an art but it's also gratifying to see how much of a change it really can make. As Don said, you can do this anytime, no cause for concern at this point. 73, Jeff N6GQ On 3/16/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Nick, I wholeheartedly second this.

Craig AC6NN -- Original message -- From: Don Wilhelm [EMAIL PROTECTED] Nick, Sometimes the filters (particularly the narrower ones) do not respond well to the initial numbers in the manual because the filter center may be shifted a bit due to the particular set of matched crystals supplied. I don't think you have a problem. There is a solution, and that is called 'Spectrogram', which will provide a visual display of the filter shape and positioning on a computer screen. Download the last freeware version (5.17) of Spectrogram from www.n0ss.net and look at the instructions for using it on Tom's website or the Builder's Resource page of the Elecraft website. You could let the filter alignemnt wait until you have the rest of the K2 built and the KSB2 (if you added that) installed and then you can do a complete dial calibration and filter alignment.

Re: [Elecraft] K2 Filter settings
Nick you did not say if you are receiving CW or SSB (i presume likely SSB since it is more BW dependant in fidelity). if you dont have the SSB adaptor installed, all the filters may be a little bit narrower than many HF rigs. when/if you add this board you will have an even higher fidelity SSB receive signal. if you get some decrease in intelligiability with narrower BW, no reason for alarm yet. I suggest also listening to both USB and LSB to see if you hear a difference. do download spectrogram and the application note at the Elecraft site (and/or use instructions at other's websites). it takes just an audio cable from your K2 audion output into your PC soundcard. software settings may take some patience to get them set up, but you will be rewarded by 'seeing' your filters. and for fun you will likely check out your other rigs! enjoy your K2 build! 73, curt - Original Message From: Nick Henwood [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Friday, March 16, 2007 6:20:04 AM Subject: [Elecraft] K2 Filter settings Thrilled to get my K2 working on 7 MHz receive but I seem to have a problem with filter settings.
