Probably needed to compensate for slow action with subtones and digital decoding.

You can actully hear the loudspeaker audio rising slowly to full volume during the first couple of milliseconds and it is not like other scanners that you have a distinct on/off type of click.

Of course you notice this only on transmissions that do not have a constant carrier, like in the airband and marine frequencies.


Ah ok. Well that makes sense. I guess there is not a lot that can be done about that since it is a hardware issue.
Thank you Ubbe!
