Set the external receiver for reception on 29.6-
29.7 MHz . The O SCAR 8 Mode J tran sponder al so
inverts signal s.
Plea se note that, becau se of Doppler effect and
other reason s, the frequency tran slation may not
be preci sely linear, as might be in ferred from the
above discu ssion. Some preci se zeroing u sing the
external receiver may be nece ssary.
Note:
When u sing the FTV- 901R on O SCAR
Mode J, along with an FT-1 01 or FR-1 01
e xte rnal receiver, a fairly loud spuriou s
signal may be noted at 29.15 0 MHz on the
e xte rnal receive r ( 2 9.15 0 MHz receive) .
This i s becau se the fou rth harmonic of the
local o scillator ( 3 5. 0 2 MHz for band lOC),
plu s the VF O frequency (5 . 87 MHz), i s
p reci sely
the
t ran smitting
frequency
requi red (1 45. 95 0 MHz) . We recommend
that the local c rystal frequency be changed
to 3 5 . l 2 MH z.
We regret thi s inconvenience to you, but
the FT-1 01 and FR-1 01
serie s wa s
p roduced long befo re O SCAR 8 wa s con
ceived . There should be no problem at all
when u sing the FT- 9 01 serie s o r FT-
1 O l Z D, etc.

LATION
REPEATER
SPLIT INST AL-
Should your locality u se a repeater split of other
than l MHz or 600 k Hz for six aw}two meter s,
re spectively, the correct split can be installed by
obtaining an optional crystal ( see your Yaesu
dealer).
Connect a frequency counter to the cathode of
D112 ( 6 meter s) of D601 ( 2 meter s) . A dju st the
trimmer capacitor s shown in the chart below for
the correct frequency .
IN STALLATION OF OPTIONAL MODULES
l . Remove the top and /or bottom cov er of the
tran sverter, to allow preci se in sertion of the
unit to be in stalled.
2.
Care fully slide the module into th e correct
po sition Do not force the connection .
3.
Replace the cabinet covers . In stallation i s now
complete . The module has been care fully
aligned at the factory.
