[Kenwood] TS870S 10 meter error

[Rob Atkinson, K5UJ]

Hi, thanks very much you guys.  Yes, mine has the SO2 which I installed.
Great.  I probably didn't even need it either, since I use it mostly on SSB.
I got it partly because I wanted to increase its resale value if I ever sell
it.
I also noticed that if I keep tuning up band and change out of 10 and back
in
again it is okay on 10 meters above 28.490.  so there is something from 445
to
490 the PLL doesn't like.  I never operate on 10, and if I did, it would be
with
another rig anyway.  I can live with it, but who knows, i may want or need
to
sell it some day, or maybe I will need to run it on 10.  While it is still
under
warranty I should get it fixed but I sure hate the idea of sending it out.
with my luck it will be fixed but they'll break something else or UPS will
smash it up on the way back.  Anyway I am near AES and I can drive it
to them.  Unfortunately  I didn't buy it from them but maybe they will
do a warranty repair.  I'll call them and ask.

Alan, if you could tell me about that bulletin I'd appreciate it.
If it is on paper I'd appreciate a summary, or if it's electronic
and I can download it, a URL.

tnx

Rob/K5UJ

Rob,

UL does not stand for Upper Limit, it stands for UnLocked.  The ERR
FE
is the message that you get when the PLL unlocks.  Unfortunately, it
is something that indicates a problem, not something that indicates
that the upper limit of the tuning range.

Does your unit have the S0-2 TCXO?  If so, there is a bulletin that
describes a condition where the PLL may unlock after installation of
the TCXO.  I think I have it around here somewhere...

73,

While tuning my new TS870 across 10 meters for the first time just
now, I encountered something not covered in the manual:  When I got
to
28.445 MHz, the status display to the right of the frequency switched
to ERR FE and the rig sidetone started sending UL in cw repeatedly.
Moving the tuning knob did nothing to restore normal behavior but
changing band to 12 meters brought the rig back, however it won't
tune
above 28.445 MHz.

My guess is that my rig has not been programmed for the U.S. and I
was
sold a rig that was intended for some part of the world where
operation above 28.445 is prohibited (UL = upper limit; ERR FE =
error
frequency).  I'm further hoping there is one of these "secret menus"
for the 870 I can get into to fix the problem and someone on this
list
can tell me how to do it.  Am I really going to be this lucky?  the
Yaesu Mk V has something like that where there's about 9 options for
coverage for different regions.  Sure hope this isn't something where
it has to go to a tech. for reprogramming.

tnx
