There is a second set of factory / service menu functions F01 to F59. WARNING:
changing these may reset all the memories. If you intend to make any changes, record all
the original values first. Most of these settings are unique to each radio and are
determined by using alignment procedures described in the FT100 Service Manual.
Do not change these values unless you are sure of what you are doing. To activate them
put the transceiver in VFO mode and turn it off. Press and hold the A,B,C keys; while
holding them in, press and hold in the [PWR] switch for 1/2 second to turn the transceiver
on. Now let go of all keys. Then press and hold the FUNC key for 1/2 second to get to the
menu and then rotate the select knob to get to a second menu (F01 to F59) after #66 or
before #01. When you turn the rig off and back on it returns to the normal menu.

AM Settings
Gary Mitchelson, N3JPU, has done some interesting tests with the AM settings and found
some settings that work much better than the defaults. The parameters that sound the best
are: PO set to 25, Mic gain to 40 to 50 and Carrier Level set to 225 (F51 menu). You can
hear a sample of his testing at: http://mywebpages.comcast.net/n3jpu/
Most owners who have had difficulties with AM audio quality have reported that the 6k
HZ option AM filter (p/n XF117A) is an absolute necessity for both transmitting and
receiving in AM mode.
The following procedure will result in excellent AM transmit operation with the FT-
100(D). The User's Manual does not include any guidance regarding this. For this
discussion I assume HF AM operation.
• Install the 6 kHz filter. You need the filter in order to have proper AM operation.
• Turn on the unit while holding in the A, B and C buttons in order to access the
sub-menu "F" functions.
• Place the unit in AM mode.
• Set the MIC gain setting to 17 (seventeen).
• Using the F51 function, key the mic and set your un-modulated carrier output
power to 25 Watts, no higher.
• That's it. You should now have 100 Watts PEP on voice peaks which is 6 dB (4
times) the un-modulated carrier power.
Extra hints: Set function F15 to 170 in order to avoid non-linear compression on voice
peaks. But note the original setting and restore F15 to the factory setting when you
operate SSB and CW. You should have 100 Watts output in CW mode when F15 is
properly set.
You can use the speech processor during AM operation but you must not exceed a setting
of 17 when using it, just as with non-processed operation. The PROcessor control is
simply a second MIC gain control which over-rides the MIC gain control setting
whenever you enable the PROcessor. The FT-100(D) actually does not allow you to vary
the compression percentage.
AT-11MP Autotuner
Some owners have opted to purchase the AT-11MP auto tuner from LDG Electronics.
This is available in either a kit or assembled format and does not suffer from the
CAT/FC-20 limitations.
There is an accessory for the FT100/D called the OTT or 'One Touch Tune' available
from W4RT.com that allows you to use the 'Tune' button on the FT100 to control the
tuning function of the AT11 directly from the FT100. It also allows you to maintain the
CAT compatibility which is something you normally lose with the FC-20 autotuner.

ATAS-100 Autotuning
The tuning behavior of the ATAS can cause confusion unless you understand the
algorithm it follows to find a good position. Normally, if the ATAS is installed correctly
and it successfully autotunes itself, it will always go in the correct direction when you
press in the TUN button for 1/2 second once it has found its first good match. However, it
the ATAS cannot find a match, it will run all the way to one end, turn around, and start
over. This process can take a while since the antenna runs 'open loop' when it loses its
position. Since it doesn't know which position the antenna is in unless it makes its own
successful match, it needs to be sure it has gone all the way to the end before reversing,
which can take a very long time.
Anytime it is not sitting right where it found a match all by itself, it can end up starting
out in the wrong direction next time. Examples would be if you manually do even just a
little fine tuning, or if you interrupt autotuning and change bands. Then the rule is very
simple: it starts the next autotune by going in the last direction it was going in, which is
not necessarily right. If it's going in the wrong direction, the antenna will move all the
way to a stop and then it will have to turn around and start over again after a long delay.
If you recognize that it's going in the wrong direction, you can avoid the long delay by
aborting the autotuning process by hitting the TUN key momentarily, then manually
move the antenna just a little (with the PTT and up or down keys) in the correct direction,
and then recommence with the autotuning procedure.
