FT-90 Problems

[Bill Atkinson]

I seem to be experiencing a problem with my FT-90 and was wondering
if anyone else knows anything. The radio works great on both 2m, and
70cm. On the 2m side, any frequency in the 147.x range causes
intermitant receive. I have a particular repeater I monitor here in
Indianapolis, 147.015, and when the repeater is active, my radio does
nothing, no s-meter, nothing. If I open the squelch past the breaking
point, all of a sudden the meter goes full-scale, and I hear everything,
but when the repeater traffic is over, my squelch is open, and closing
it will again make the repeater impossible to hear. I see this occuring
on a simplex frequency in the 147.x range also. I use the radio on
several 146.x repeaters, and it works wonderfully. I've only had this
radio about 8 months. Any ideas?

Yup. Sounds like you might have ctcss decode or dcs decode enabled
for the frequencys you're having trouble with.

CTCSS is not an issue here. If it were, I would still see the S-Meter, even
though the audio would not be present. When I close the squelch past the
breaking point, then entire S-Meter flickers, and disappears, like its not
even receiving..... Somewhere the receive is cutting out....

my guess would be a VCO adjustment although i could be wrong.
good luck.

I have a brand-new Ft-90, which seems to have a similar problem. I am
in Los Angeles, and experience the noted condition on strong repeaters
around 449. Mhz. I have thought it might be a VCO problem, as tuning
off freq by 5 khz allowed the squelch to work in one instance.
However, it doesnt help on the transmit freq to be off by the same
amount. What's up??

The guy at HRO in Burbank seemed to know exactly what I was talking
about when I mentioned this problem to him...I suspect we are going to
hear more about this problem.

Bill, et al...I just got off the phone with Yaesu tech support, here
in LA. The tech had me reset the computer, and the problem went away.
He said that perhaps a wrong value had snuck into a register for one
of the local oscillators, and had thrown it off freq just a hair.
The reset goes like this: turn off the radio, depress both
arrow keys and the disp/ss button, and power up. This takes it back
to the basics, including wiping out all your memories, but it does
solve the problem!!

good luck, 73 Geo.

Wait, there is more...it turns out that the 440 band will show squelch
problems if you have reset the STEP function to other than 25 khz.
This shows up in LA as we have a new band plan. I had reset mine to 5
khz, which seems to be tied to the squelch somehow. I have
communicated this to the yaesu phone tech line, and will also email
them.
