I think this is the version I have been working with and “rewriting” wen I find a nugget of information.?
I hope three is a better version. Barring that I hope that a Chinese manual may be obtained., preferably on line.
Googol is pretty good at translating.
I can’t believe that Chinese hams would tolerate the type of manual I have seen nor the absence of any written details.
