The only a few issues I know of is they sound a little flat in factory form. There is a ham that modifies your microphone and then they sound great. My Friends used to run hot and he had to sign off to let the rig cool. There is a temp meter on the front panel so you can tell when its getting warm. A fan of course, Cures this problem.
The other thing is that the band scope is not really usable. It uses the same receiver has the main receiver. So you cannot have the band scope on at the same time as you are receiving. The scope makes a very slow pass across the band. Then stops. Its not like a 756 Pro icom where the band scope is on all the time if you wish.
I am thinking of putting one in my Truck. Just need to find a good price.
