AUXILIARY BAND RECEPTION
In addition to
the
amateur and major shortwave broad-
cast bands, the FR-101 may be programmed to receive
four 500 KHz-wide ranges covered in Table 4.
The crystals can be ordered direct from your dealer.
When ordering, be sure to specify
that
the crystals
you
desire are for auxiliary band use in the FR-101.
The PRESELECTOR tuning range
is
given in Figure 5.
On RI, t.2 and M position, the FR-101 will work
properly
by
only inserting the crystals, however on
t.
3
position, TC22 must be adjusted
as
follows:
1.
Insert the crystal in
t.
3 socket.
2. Set the BAND switch to
t.
3 position.
3. Push the CALIB switch on and tune the FR-101 to

4. Peak the PRESELECTOR.
5. Adjust TC22 for maximum S-meter reading.
Insert the crystal
of
the correct frequency given in the
Table 4
to
the corresponding crystal socket located on
the right side
of
the chassis. The crystal socket accepts
standard HC-25 /U type crystals. In order to receive the
desired band, the BAND switch must be set to the
number corresponding to the crystal socket
in
which the
auxiliary crystal in use
is
installed.
A fundamental frequency
is
used when the cyrstal
frequency
is
lower than 28 MHz and the second
harmonic when higher than 28 MHz.
It
should be noted
that the bands covered in Table 4 work only when the
appropriate auxiliary bands are used
as
listed in the
Table.
