Re. Yaesu, Model 102 Series, Amateur Radio Equipment
Greetings from Toronto, Canada! I hope you will find the attached Yaesu manual
helpful. I have been assisted many times, by Hams whom have kindly made manuals
available for free via mail and the Internet. I would like to take this
opportunity to now make a contribution of my own.
I have noted the famous Yaesu Model 102 Series of radio equipment manuals absent
from the Internet. I am a happy owner of a complete Yaesu 102 station and in
possession of its manuals. Hearing of many requests for the manuals, I have
scanned my collection and present it to you here, free of charge. I do so with
the hope that it will assist you in keeping your own Yaesu 102 equipment running
forever and as correctly intended by the factory. I also realize how frustrating
it can be trying to remember the forgotten instructions of a destroyed or
misplaced manual!
I request that these files remain free for private distribution and personal use
by fellow licensed Amateur Radio Operators only and that they are to be
considered as if "on loan". No fees are to be charged for, or as a result of
their use, nor are they to be published publicly. They are provided for private
personal reference only and if shared with other Hams, I ask that the credit for
the scanning and free "loan" remain with me.
I look forward to your continued support of the excellent FT102 Transceiver and
Accessories and helping to build both its continued demand as a "collectable" and
its assured respect in Amateur Radio history.

yours truly,
