Here's a good review of the 9700 that's both pretty short and pretty thorough. 3xyGuOvVQsU

What I like a lot about this review is that it also tells you what the radio can't do. For example:

• At 3:47: “Full duplex but cannot do crossband repeat”
• At 4:48: “DPRS sends your position info [...]] into the APRS system via a DSTAR gateway [but it can't] do traditional APRS analog transmission or reception.
