Well, as the title suggests, I'm placing my XTR-330 on the shelf and bought myself a new Pro-78se. I haven't had too much time to do testing with it today but it sure seems to be a lot chattier than the 330.
I'm in a suburb (Tacoma Metro area). On filter 0/1 it seemed to pick up itself in constricted allies, either that or 4 different cars had RD's lol. I switched it onto Filter 2 and it doesn't even alert to half of the K band door's the 330 would. I don't know if I should be scared or not lol. Either way I'm going to give it a week or so to get a good feel for it.
My current settings:
SR=ON (I've seen it used where I live)
Oh, and I can easily test KA now... If i turn on my 330 my 78se alerts to 33.8 for a minute
**I do not run both RD's at the same time.
