Squelch settings for FM and SSB
As shipped, the squelch threshold on the FT100 is the same for FM and SSB. As you
change from 144 Mhz FM operations to HF SSB operation it's preferable to have the
squelch open up in SSB mode and then close when going back to FM mode without
having to change the SQL/RF control all the time.
This can be accomplished by changing Menu F08 (SSB SQL) in the secondary menus.
For example, set the F-menu F08 value from 003 to around 050 to get the desired squelch
behavior.
Storing memories remotely
There are no programs currently available to store the FT100 memory settings remotely
because Yaesu did not leave any provisions in the rig for uploading or downloading
memory locations. There was a rumor that RT systems was working on a version of
ADMS software to provide this capability but they have confirmed that this is not true.
The FT100 has more than 300 memory locations and if you intend to fill them all up, be
aware if you ever reset the radio, they will be lost.
There are also no provisions for labeling the memory locations with alpha-numeric labels,
most likely because the main display uses 7-segment characters for the main frequency
which are only appropriate for displaying numbers, not alpha characters.
It's probably best to think of the FT100 as a mobile HF rig with UHF/VHF capabilities. It
can't compete with all the features you would find on a radio designed specifically for
VHF/UHF operation.
SWR meter interpretation
There is no mention in the FT100 manual how to interpret the SWR bar graph on the
FT100 display. The following measurements were made on the 10M band by moving the
antenna very carefully to get the appropriate number of SWR bars on the FT100 and then
disconnecting the radio and measuring the SWR of the ATAS100 with an MFJ259 SWR
Analyzer. The HighSWR icon came on when an SWR with 7 or 8 bars was showing.

2 1.7
3 1.9
