By the old TASO standards, you need over 40 dB s/n to get a nice picture, which requires a lot more peak RF power. By comparison, the digital signal needs only about 17 dB s/n. What happens at a 12 dB s/n for both? That's probably what happened here during Hurricane Ike. -- 73, Cecil http://www.w5dxp.com |
