This is not the original Instruction Manual for the 1-
Hz Option for the WJ-8718A Receiver Series, it is only
an attempt to write one from scratch.
It is based upon visual inspection and visual circuit
tracing on existing and unmodified WJ-8718A and
WJ-8718A/MFP receivers including this rare option.
The author is Paolo Viappiani of La Spezia, Italy
(pviappiani@tin.it), a radio collector whose only
purpose is to share technical information. It is a no-
profit work and consequently in no way this manual
may be sold and/or made object of commercial
transactions.
The work is still in progress, so any contribution and
suggestion is very welcome. The author also
apologizes for eventual ad unwanted mistakes,
misprints or omissions of which he cannot be held as
responsible.
