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. 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? I am reluctant to proceed until I have sorted it out. 73 Nick G3RWF _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
