For me it's not an issue of bad sensitivity with VHF / UHF, that's fine. The issues for me are the high degree of interference and white noise on VHF/ UHF analog. I almost never use my SDS's for VHF / UHF analog because of these issues. The interference issue is mostly a problem on the SDS200 with rooftop antenna, but it can be a problem on the SDS100 at times. The white noise issue becomes a problem mostly with the SDS100, when receiving weaker stations. The SDS100 actually seems to pull in weak stations well, but the white noise can be louder than received transmissions....strong and raspy. I look at the SDS's as digital scanners with the ability to handle analog as a secondary mission. If simulcast isn't an issue, definitely buy an X36.
