I find it very hard to do. First thing is that the display looks like a rapidly squirming worm, changing shape constantly around the inner most ring. I can get it close to appearing about in the same place but it still goes ccw and cw slightly with modulation and still goes CCW overall. Where as with the Panadaptor in Spectrum, DSB 16k filter, I get the center signal peak (carrier) as close on the Red line as my eye can see (Zoom to 4x+) But it still sounds off. The clock tick still sounds fuzzy, and the mans voice sounds like it has a tad of 'ac' on it. The numbers for the DDS are -7709, PLL 1, IF 11025 (my best WWV Sig strength is 10.000 usually +20 over, -59dBm on my screen) ----- Original Message ----- From: "Ray Andrews, K9DUR" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <flexradio@flex-radio.biz> Sent: Thursday, July 26, 2007 9:40 AM Subject: Re: [Flexradio] FlexRadio Digest, Vol 27, Issue 25 > Harry, > > 1.)
