[Scan-DC] dropped transmissions muttgummery

I have the SDS-100 and while I haven't done enough side-by-side
comparisons... Just driving around Montgomery County from Silver Spring to
Potomac (and between) the SDS-100 does seem to pick up on a bit more than
my BCD436HP. I also have an older PSR-500 in my car but don't really run it
much. I will say that in a lot of conditions I got better performance from
my GRECOM than my 396XT. But I'd probably place the 436HP above the PSR.
SDS-100 is definitely at the top. The big downside I've had with the
scanner so far is the volume peak is a good bit lower it seems than other
Uniden scanners.
So to answer your question - I can non-scientifically report improvement.
