For those hoping for up-dateable firmware this is a disappointment.    
(from "Letter of Attestation" document at above site)



"T his letter attests to the fact that Kenwood scanner receiver models 
TM-V71A /
TM-D710A meets the requirements of the FCC Rules, 15.121(a). Compliance is
achieved through the following method(s):

(1). The Microprocessor employed has internal flash memory, however the
programming information cannot be read out from the Microprocessor, 
therefore it has
same means of protection as a masked Microprocessor .

(2). The Microprocessor is not to accept programming, selection, 
scanning or direct
entry of Cellular band frequencies.

(3). Filtering precludes reception of mixer images or harmonics of 
Cellular band
frequencies.

(4). Subminiature SMD assembly and inaccessible multiplayer PCB 
construction all but
precludes attempts at circuit hardware modifications.
