Tom,
I have used VA Beach 2 times in the past dozen years and no problem and
fast turn around time. But not cheap. John mentioned Avid (Cliff
Holland) and may not be aware that he is back in business. He is kind of
a guru on Kenwood HF stuff but not sure if he works on your rig. Drop him
an e-mail

Also check his reviews on e-ham.
