Wondering if Uniden will be including both CB AM and FM modes in their National listings? (I know it’s a simple matter to switch the CB band to capture both by selecting “Auto” in the Modes menu but just spitballing here!)
Ok. I want to run something by you. I attend military air shows. I believe the USAF Thunderbirds have used (on occasion) both AM and FM modes during their demo flights. I have set the mode to “Auto” on my SDS100 and BCD436HP without issue. I’ve listened to an AM signal while the scanners were set for FM and vice versa and have noticed a difference in intelligibility due to choosing an incorrect mode. I’ve also set the scanner to “Auto” and had no problems regardless of the actual modes. Does this sound like it agrees or disagrees with your take on the “Auto” setting?the auto feature only uses the band defaults in the radio.
with some of them you can change the default in settings, but it is just one or the other.
it should have said "default" and not "auto".
When you select AUTO for a channel, modulation, or step, the above values are used unless you’ve edited the Band Defaults. Set Modulation Set the demodulation method to use for the range. AUTO uses default modes based on bands i too have heard AM/FM things and made out what was said. i have a long story about hearing a plane landing during and airshow that they did not hear because he was using FM. they told him to "land and bring your license to the tower" i called and told them what the problem was, my phone call was not well received. but it might have saved him. they seem to be harder to hear the farther away they are. |
from the manual,

What above values?
Set Modulation Set the demodulation method to use for the range. AUTO uses default modes based on bands

In my opinion I cant see this as practical. Or maybe not until there is a national consensus on FM mode only channels. The scanner will pick up FM mode signals while in AM. The audio just sounds really crappy.
