Generally speaking good copy; a few pages too hard contrast...
Good service and communication.
 ;
I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.

Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.
;
Clear and easy to read. All details as expected. Price acceptable , and quick delivery.
;
Quick response and exactly what I was looking for and at a great fair price!
