I don't know about SMC, though another Yaesu dealer claimed to know nothing
about the problems with the FT-5200 when I took the rig back to them last
year.

Yaesu Head Office definitely know; I copied a plethora of postings from
rec.radio.amateur.misc referring to various subsets of the same problems
on both the FT-5100 and the FT-5200

I only have one speaker connected, but it basically sounds like one of
the same faults that mine has (all the time, not intermittant), and was
one of the faults commonly discussed by other owners in rec.radio.amateur.misc

Me too. Yaesu UK have said that the rig is in spec, so that's the end of
it. I just wish they'd come clean and own up to the fact that there are a
large number of very dissatisfied FT-5100/5200 owners out there, instead
of trying to sweep the problem under the carpet - if nothing else though
it highlights the value of Usenet. Without it, I'd have believed them!

I got this twice ! - Both times intermittent coming through the
internal speaker.

First time around, the rig went back to my local dealer, it was then
forwarded to Yaesu UK.  The rig was less then 6 months old, and to say
I was unimpressed is an understatement.  2 weeks later it came back,
and it seemed okay at first, but of course, as the fault is intermittent
and I don't use 50 W on 2m very often, I didn't realise that it was still
there.

Excuse: Dry joints.

A couple of months later I noticed that it was still there, and took it
back.  This time the rig was away for 6 weeks, and less than a year old.
I went into see my friendly local radio dealer, who all of a sudden were
not so willing to be helpful.  A case of "We have your money now***off",
I felt.  They gave me Yaesu UK's phone number and told me to contact them,
(see my feelings about the dealer above).  I did this and was told as said
in here, that because the rig was in spec, it could not be replaced.  The
local dealer wasn't interested, because they would not have got a
replacement rig from Yaesu had thay given me a replacement themselves.
I had to phone this man at Yaesu several times at daytime rates, the
call not being local either, I had no use of the rig for 6 weeks, and
all they could do was say "Well we are looking into it, but as the fault
is intermittent we are finding it difficult to replicate the descibed
problem" and "...as the rig is operating within spec, we cannot replace it".
Christ, these people must be tight as arseholes, you would have thought
that after 4 weeks without any success most companies would have said
okay we will give you a replacement, but obviously not Yaesu.

Excuse: The PA block in this and some other Yaesu rigs is prone to
oscillation, we think that is the problem.  We blew up your original PA
during testing, so it has now been replaced.

Well thank christ they blew it up !  The only thing that's not covered
in the Yaesu warrenty are the power semiconductors.  I thought it was
most reassuring to know that not only the FT5200 suffered with this
oscillating PA problem !

I've only used the internal speaker so far, but I'll have a look at this
with mine when I have time.

Yeah, and me too.  I could stand the fact that the rig went wrong,
(it happens) but I didn't think that I got anywhere near receiving a decent
service from Yaesu UK.

If I used 2m/50W a bit more often, I wouldn't be surprised to find that
the fault is still there (have not used it for ages now).

Personally I have decided to steer clear of Yaesu products in future.
