A few years ago I did a frequency response test of the V7A, and the 
results were bad on 1200, OK on 9600 TX, and marginal on 9600 RX.  See 
http://www.febo.com/packet/layer-one/kenwood-tmv7a.html for details. 
Note that I didn't test turnaround time or other factors that would 
influence throughput.
