Please explain how precisely tuning in a station improves reception during selective fading. This makes no sense to me. I can't explain it. All I know is that the 2100 using the bandspread sometimes gives me a better signal than the 800 using the sync. They are both using their internal whip antennas, and are side by side on the table. The 2100 performs *much* better than the 800 without using the 800's sync. Selective fading is much less drastic. Turning on the sync on the 800 *usually* makes it perform better than the 2100, but not *always*. You are comparing two radios with different circuitry and specifications. What you are seeing (hearing) is most likely a difference in radio performance. Speculating for a moment I could guess that the 2100 might have greater dynamic range or maybe a faster AGC that can follow the a rapid fade over the SAT 800 but there is no way I can understand the statement that precise tuning can equal using sync detection. Using a standard AM detector and tuning a station spot on compared to being slightly off tuned is not going to make an improvement in a fading signal that using a sync detector is going to make. Generally, I have found that precise tuning allows a sync detector to maintain lock on a weak signal. -- Telamon Ventura, California |
