Ok, after a lot of looking at, and reading different forums, I pulled the trigger on the SDS100. I have down loaded Sentinel, and Proscan, and I am overwhelmed!!! I am an Extra class ham, and I am pretty well versed in CTCSS, Offset, and all the normal ham stuff, but I am concerned. Is this piece of equipment that complicated (I have 4 D-Star stations, HF, etc). Can anyone offer some advice to make this a little less cumbersome? I will be checking out youtube tomorrow, scanner is due here Monday.
