Group, Thank you very much for the information. A few people contacted me off list and of course, Eric's response helps tremendously.
Will start looking for someone, organization or individual, that may be able to help or do the conversion on these units. Have 4 of them. And another two meter unit although not as concerned with it for now. The duplexers, same thing. Also, looking for conversion notes. May have found a manual but will be looking if not. Willing to pay for help, manuals, notes, etc. If anyone has a contact or knows of someone that may have converted or worked on these units before, please let me know. Thank you group, your help is greatly appreciated.
