SSB, HF and other features would be great. If the hardware could support this, Uniden could do a paid upgrade and make some additional money.
Just because another radio supports something does not mean people that may own the SDS100 may not want or need the feature.
Even FM Broadcast and Digital TV audio are useful. Someone commented the other day why someone would want to listen to FM Broadcast on a scanner, the comment was like why bother. Well I often need and use FM Broadcast during car racing where either a local radio station is broadcasting the even or the size uses a low power FM broadcast transmitter. Also during major storms and power outage or in a really bad disaster situation having access to FM Broadcast is actually quite useful. Sure you may or may not have a car FM radio to listen to, having an all in one radio is quite useful.
I hope Uniden is working on lots of things behind the scenes for the SDS100. Hopeful they have a small remote head, IQ Output, Discriminator Output and so forth with the Micro USB port.
Additional features would be nice to have.
