I am on my second one. Had an original very low serial number 775 with DSP added by the factory. Just replaced it with a late build version about a month ago. Going from years of Kenwood 820/930/940 rigs I can honestly say the 775 was not a disappointment. Mine is used almost exclusively for AF MARS both phone and digital. Solid audio out and you can't beat the dual watch for another $2000. ENJOY IT! 73 Dan R W0NBX
