Re: [Flexradio] Panadapter center frequency error in the SoftRock 40 mode in Beta 1.4.5 Preview 4
Hi Mike, I noticed this with a V5 SoftRock which has a center freq of 7.040 -- the band edge glitch was pretty apparent. Have traded some mail with Eric @ Flex about the glitch and expect a fix in the next drop. Cecil - 1.4.5 pre 4 or so and beyond have support for the Soft Rock built in.

The center of the viewable range is still 7.056000 and as you tune to the bottom of the 48kHz range you are off of the pan adapter noise display (to the left) and when you tune to the high end of the 48kHz. range you do not reach the high edge of the pan adapter. Frequencies that are within the display range are accurately measured. For example W1AW on 7.0475 is right on the nose after the correction has been entered. Another way of saying this is that the Panadapter range is skewed by the amount of the difference from 7.056000 that is entered into the Center Frequency correction box. I hope this is clear as I am having trouble putting this into words. 73 - Mike - K9JRI ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz

Does that beta version support the SR-40 or do you have a special overlay version?
