I owned the sds100 but I have a 200 now which is one of the better all around scanners if care is taken to optimize it and learn it. I have owned at least the same numbers as people in this post for at least as long as those who are comparing apples to oranges.
Yes, the old units were good in many ways, but one has to consider the entire scanner experience and I never liked making blanket positive or negative statements without considering the big picture.
I saw nowhere in this post where there are any specific things listed that would put the 100 in the trash. Would I buy another one? Yes, but with other unidens, icoms etc I did not need it.
If one is talking about strictly sensitivity then maybe the sds100 falls somewhat short, but my 200 is fine with the appropriate antenna and with the filters I got my 100 to be very competitive. Yes, it is not plug and play like the older units.
I ,too, owned an r6 and it was a great little unit, but no comparison to either the sds series or other current scanners in terms of programming ease especially with software or bank/favorites scanning. The r6 is a great receiver for a specific use not including trunk, digital or simulcast or ease of on the go programming. I also owned Relm so I am not inexperienced. Each radio has its place and
I respect everyone’s opinion but please supply specific reason why the sds does not work for you.
