I know it's possible to do a modifiction to have the squelch working in
all modes with a Kenwood TS-14S.
I would like to know if some of you have already made this mod and if it
really works.

Thank you in advance,

Even though I've owned and operated my share of Kenwood rigs, and never
heard of the problem that you describe, it surprises me that the squelch
is
not intended to work in any particular mode. Which mode is your squelch
inoperative?

It's odd. There were some SSB only VHF rigs in the seventies, and
they generally did include squelch (though I have no idea how
well they worked or if people actually used it).


Then the multi-mode rigs came along, and at least some of those
rigs had squelch that only worked on FM. I'd guess it reflected
operating habits, you want the FM rig left on in case someone
hits the channel, but for SSB you generally aren't just waiting,
you are actively tuning. Plus, you can get a feel for where
to set the squelch for local FM, but how much would you miss
if you had the squelch turned too high? By the time you get
the rig squelched on SSB, you likely are missing the weak
signals.



I have a Yeasu ft221 for vhf that stays on all the time. It did not come
with a squelch for ssb but did for FM. I found a way to squelch it for ssb.
Almost all activity on vhf will be on 144.200 or 50.125 to start with. It
is seldom the band opens that this is not the starting point. With two
rigs on, one for 2 meters and one for 6 meters, it would be loud in the
shack if they did not have a squelch for ssb. Also there are some local
hams that monitor certain frequencies on 10 meters for local work and the
squelch comes in handy there also. Same for some special interist groups
and nets on the other bands.

I would miss the squelch on the rigs if they did not have them. Lots of
times I monitor an 80 meter frequency while working on the computer in the
shack and do not want to hear all the noise if no one is talking.
