7 years ago It uses a threshold --- it doesn't consider the rest of the band at all. The process is like:
- Continually scan through the channels.
- Stop once a channel has been found with RSSI over a certain threshold.
- Start homing in highest signal between this channel and the next N channels. Record RSSI for every N channels.
- Settle on the channel with the highest RSSI within that range.
I've been running into the same problem though, as have others in my group. Some things that need looked at:
- Tweak thresholds (I think it just needs lowered a little and it might solve it)
- Play around with how far up the channel range for picking the best signal.
- Actually use local minimums. (e.g., scan whole band then detect local minimums, allow instant selection rather than continual scanning)
From what I could tell during race day, auto mode only considers the highest RSSI across the whole band and not local maximums, so you can't flick from racer to racer, you will always home in on the strongest signal. I do like the ability to not have to manually dink up those last 5-10mhz to get to the center, though.
