160m-Transnitting Spurious
--------------------------
Three FT-1000MP were sent back to Yaesu-Germany because of the transmit
ting spurious problem, reported earlier.
All these 3 radios showed poor spurious attenuation while beeing used in
the 1820..1826 frequency range. Local stations 20 miles away detected the
spurious while transmitting barfoot.
Yaesu now claimes they have realigned the unit and improved the spurious
signal attenuation by additional 10dB. Mine came out with -67dB, the other
rig -66dB and the third unit is supposed to be at the -70dB level.
You know the signal strength of your neighbor. Subtract 60..70 dB and you
have the strength of his spurious when using the FT-1000MP. I hope very
much not to get any more spurious signal reports from outside Germany
as long as I still use the 1000MP.
We were also told, there is no way to further lower the spurious output.
If these numbers are true, there should not be left much of a problem.
Who knows what other spurious will pop up now after the units were
optimized for 160m use?
Erratic Clarifier Problem
-------------------------
My radio showed a very erratic behaviour. While trying to spot a caller
the frequency and the display jumped all over the place. This problem
was reported by others also.
Yaesu did replace a little (cheap looking) thing, what they called an
encoder. It looks much like a very cheaply made potentiometer with no
stops. It is the thing you use when turning the clarifier knob. I do not
think it is a real optical encoder. They obviously have replaced the more
expensive optical encoder by some cheap potentiometer and a tricky but
less expensive electronic.
Well, they replaced it and so far it does work as one expects a clarifier
to work.
I do not trust the 1000MP anymore and will replace it somehow. I probably
return to some radio which still has a real S-Meter with a pointer and
scales. This is what a radio should have anyway.
