Memory Programming - Yaesu FT-100 Undocumented

There is also an FCC site that has manual, schematic, and other information related to the
submission for approval by the FCC. Unfortunately, this information is quite out of date
since a product is normally submitted to the FCC well in advance of its actual availability
and the manual is often just a rough draft of the finished manual. An exploded view of
the rig can be found on http://k0lee.com/images/FT100%20Exploded%20View.pdf.
There is also an effort underway to make the alignment procedures available on
http://k0lee.com/techsupp.htm.
The FCC site can be found at: http://www.fcc.gov/oet/fccid/. To get the information, use
the Grantee code K66, and the equipment product code FT-100, and select View
Exhibits. Here you may view schematics, photos, block diagram, parts lists and a PDF
version of the user manual. The manual shown appears to be only a rough draft with 36
pages of information vs. 108 in the finished manual. It contains no illustrations. The
manual and schematics were scanned and converted to .pdf and you will find resolution
of the schematics is not high enough to be usable. It is highly recommended that if you
lost your manual or bought a used radio without one, that you contact Yaesu Parts and
purchase a new one.

Memory Programming

There are a few common difficulties in programming the memories. The radio has a
mode to allow rapid tuning through the memories by skipping unused memory locations.
This feature must be disabled to store frequencies in an unused memory location. To
disable it, place the rig in memory mode by pressing the VFO/M button until MEM is
shown in the display. Then hit the STEP key to enable or disable the vacant memories
selection. Reverse the procedure with the same sequence. Turning the SELECT knob will
help you to determine if the radio is in rapid mode if you see it is jumping over unused
memory locations.
Another difficulty is getting the memories stuck in a particular memory group. The main
memory [1-300] is divided up into 6 separate 50-memory groups. You can restrict tuning
to a single group by pressing in on the SELECT dial for 1/2 seconds while in MEM
mode. You reverse the procedure with the same sequence. You will see an GCH appear
in the lower left hand corner of the display if you are locked into a particular memory
group 1 through 6. Pressing the SELECT for 1/2 seconds will put it back in memory
channel mode and it will display MCH in the lower left hand corner. If you are not
careful and only press the SELECT momentarily, it will put you in VFO mode and you'll
have to press the VFO/M key to get back into memory mode. This is not explained
correctly on page 71 of the manual.
There are no provisions for alpha numeric labeling of the memories in the FT100.
