I just picked up the new Uniden BC898T this weekend it will do
everything you want except for
Alphanumeric display. It uses standard 9pin serial cable to connect to
the PC, it also has the
new 6.5KHZ freq step that commercial radios will be using. I have a
Cushman service monitor
to check HT & mobile rigs but needed something to decode DCS & CTCSS
tones & the 898
really does a good job, it will display which type of tone and tone
frequency on even the weakest signals, it also does all 3 types of
trunking and alot of other features and theres free
softwae out there for it.
