Interesting how some will tout a "return policy" from businesses, like they are supposed to be a "trial period. -That is NOT what that is for.
This is detrimental to businesses, costs them time and money, most of the time, it can't be re-sold as new, and is how policies get changed.
This sort of abuse of policies is not ethical.
And the SDS series, as well as the Unication series, are both designed with "New technology" to help overcome simulcast distortion. Other than a real portable radio, those are the only current series of scanners / monitors there is, unless you go laptop / software route.
Or you can take a couple of other's opinions, and just grab something, and hope it works.
(Again, the O.P. already has an SDS100, why not tote it with him?)
