Vic in Phoenix was nice enough to ship these out to me so I can attempt to fix my radio. These are the two he sent me scanned in, so they are not searchable. If I can do some OCR with it and make it searchable, I will. These docs have a TON of great information about the radios, so hopefully they will help someone (like me) to fix theirs if the radio doesn't work. Let me know if you have any questions. Please save and/or upload to another server if you like. If I can get them posted here in an area for easy download I will. One of the files is ~49MB.
