Hello George and Thank You for your making a informative reply.
You made excellent points and rounded out the input very nicely. While
reading your reply, it dawned on me that I meant to add another point about
the EDSP in the FT1000MP. I have seen many comments where someone says that
the only worthwhile feature on the MP that is not on the D is the EDSP, and
a external DSP will make up for that. Well, that is not true, and I only
hear that comment from some one that doesnt have a built in DSP..... hi hi
The truth is that an external DSP or EDSP can not make up for a DSP that
is a intergral part of the transeiver. The EDSP in the FT1000MP works with
the last IF stage, the detector stage, and the audio preamplifier stages.
An external DSP ONLY works at the audio leval, and in most cases, after the
last audio output just prior to the speaker (some have enough gain to use a
low leval audio output that some radios provide from just prior to the
volume control section). That makes a difference in performance. Especially
if your using differential mode receiving and need the Enhanced Digital
Signal Processing (EDSP) for the spatial performance that dual receiving
can provide to the brain.
I have been very pleased with the various options for setting the EDSP
settings in the FT1000MP. Heck, the reason that feature is being used is
because it is needed and does a great job, even with SSB voice. The
majority of users that say it is a waste of time for voice operations
either have literal physical hearing problems and must have as much
bandwidth audio possable to hear correctly, or are trying to maintain HiFi
audio that in fact doesnt contribute to Communication Intelligibility. Full
bandwidth transmitted and received audio is great, But Only Under Strong
Signal Conditions With No Compeating Signal Or Noise. When the signal gets
weak, is in the presence of noise or other signals, or has poor highs in
the audio, the facts are that reducing the lows and enhancing the highs
IMPROVES Intelligibility. ESPECIALLY from the transmitted side! When the
audio can be taylored on the transmit AND the receive side to enhance the
intelligibility speech range, the band conditions that can be handled and
the distance one can communicate improves!!.......and with out raising ones
power leval I might add.
Future versions of DSP will contenue to get better. Especially when earlier
IF processing levals can be used.
Ok two last tips. No DSP out there at this time works at the front end of a
receiver. Thus a DSP can NOT make up for the lack of good filters in the
front end of a receiver. The MP has filter options in TWO IF stages and
will make a tremendous improvment in dealing with band conditions, AND
makes it easier for the EDSP to do a even better job. Also please note,
even though DSP can do a great job in dealing with hetrodynes, even
multiple hetrodynes, the affect that hetrodynes have on the receiver AGC
can not be compensated for at the DSP leval. Receiver AGC (automatic gain
control) will decrease receiver front in gain and sensitivity in the
presence of a strong signal causing a weak signal to be harder to copy or
to be lost. For this case, use the FT1000MP variable notch filter, with the
EDSP off so you can hear the hetrodyne, adjust it for the deepest null of
the hytrodyne and then put the EDSP back online. The weak signal will be so
much easier to copy and not lost due to the AGC action. Thats why I have
set my menu control options to leave me with the independent notch
adjustments even when the EDSP is active.
On the topic of the noise blanker. Unfortunatly I live in a house that has
too many floresent lights, and variable high intensity lights in it. Some
of the houses near me also have them and fish tank heaters. There are many
occasions when I just simply would not be able to operate the receiver at
all if it wasnt for the variable narrow and wide noise filters in the
FT1000MP. I sometimes see 10/9 power line type noise reduced to less than
S5, or in some cases less than S1 and let me copy signals that were lost
before I turned them on. Weaker power line noise is frequently elimintated
totally. On todays hf bands, there are many other type of signals that
sound like noise, but are actually military communications, and
unfortunatly, noise filters in most radios will not touch them. You can
tell those signals because they only exist in portions of some bands, where
as local noise will be present more uniformally across many bands.
Yep, the FT1000MP is a daunting transeiver to get to learn, no doubt about
it. But it is well worth the effort for the enjoyable Qso's you will be
able to have because you knew how to operate your FT1000MP and use its
interactive controls to there fullest capability.
I have been a shortwave fan since I was seven years old, and I have found
this to be the best I have ever had in options for the receiver, and the
added plus of the computer interface (I will be 50 in Feb 98).
Now to get my Kenwood SM-220 panadapter display interfaced to the FT1000MP.
I was surprised not to find a IF jack prior to the first filter set for
this purpose.......but I will add it and use that old scope once again....
hi hi
Hey, these exchanges have been great are so much easier to do with those
that dont come on so heavy handed. My compliments to those that host such a
well behaved reflector operation.

Thank you Bill, WD8ARZ, for putting it all into the right words!
I have the FT-1000MP and I'm in complete agreement with your
comments on the rig. I want to also mention that when running
an amplifier in QSK mode, there is NO reason to use any 3rd party
add-on device to avoid the use of the relay in the 'MP. The
'MP has the option of keying the amplifier with a relay *OR* a solid
state switch. BOTH are built in and you use the one needed for
your particular amplifier. In my case, I have an Alpha 89 and run it
in full QSK mode with the solid state switching in use and there
are *NO* clicking relays involved! It's beautiful, switching is completely
silent, and FAST! The 100 watts available from the 'MP is much more
than I need to drive the Alpha 89, which typically runs at full output
(1500w) with ~35 to 40 watts of drive.
The 'MP is the best bang for the buck today. And speaking of $$$, that
is another area where many are misled. There is actually very little
difference in price between the 'MP and the D models. Make sure you
are not comparing apples and oranges when you make this comparison.
The D model is fully loaded and it's price reflects this fact. The 'MP
is priced *without* all the options, and this is a whole different level of
radio
when it's naked. Put in ALL the options to configure it fully, as the D
model
is, and you will find that the prices are very near the same. Yaesu
doesn't
shout from the tree-tops about this, but there are six (6) OPTIONAL filters
needed to completely fill up all the slots and take full advantage of the
capabilities of the radio! I certainly can't detect ANY drift with the
(optional)
high stability TCXO installed, either.
Switching power supplies have been used for many years now in all
commercial computing equipment. They are efficient and reliable, and
take much less space than the old analog supplies.
I wouldn't part with my 'MP for any kind of $$$.

Hello Steve, your question is a very frequent one for the last several
years. Earlier archive's for past years may also be of help to you.
Especially because it is obvious that some are rather biased in there
comparisons........hi hi
Check out the Yaesu archives at: http://www.contesting.com/_yaesu/
I have strong disagreements with some of the previous comparisons made to
the MP for several reasons. Bias of some of the presenters, early versions
for some of MP's used in the comparisons, and perceptions about why one
radio HAS to be better than the other. Each has applications that suit some
users better than others, but they are not the same apples.
The facts of the matter are that they are TWO Different Radios. Each has
features that the other doesnt and represent different objectives using the
technology available at the time each was designed. Price has come way down
for the MP also.
Also note that the 200 watts compared to 100 watts is only 3db, which is
only a half a S unit on a S meter....but boy does it need a bigger hotter
running power supply. Try running the Ft1000D on 12v..........grin. The
only time that the extra hundred watts is going to be worth it is when NOT
running a linear amp, working a marginal station and using a antenna with
some gain IN the Direction of the station your working.
A current version Ft1000MP has one of the quietest phase noise receivers on
the market today. The power supply is well know for being one that is quite
and has the least effect on receiver noise and rfi issues. Its receiver
stability is very good and drift is not noticable without instrumentation.
Heck, it can resolve a frequency down to .625 Hertz! What good is that if
there was drift???
The FT1000MP EDSP is terrific. The ability to reduce fatique from the
static and Qrm on 80-160 is just plain great! It is easy to use once you
know the controls, and anyone that has read and practiced the directions
for the menu options to use EDSP on transmit find that it can create great
audio. Tune in to 1850khz with your filters wide open and listen to the
near FM sounding SSB audio from several who use the FT1000MP there. There
are many who will pass on their tips for Transmit Audio
configuration.....and its well worth the effort! Dont let ignorance on how
to do it equate to it doesnt do it well..... grin....
The display on the MP is great for immediate feedback as to what is setup
and what is going on with the entire rig. Its very easy on the eyes too.
The filters are not time consuming to select, and are easy to see what is
active and those settings store in the Vfo's and memory's. IF Shift, the
Bandpass and Notch filter adjustments work great!
Current versions do not have a problem interfacing to linear amps and nor
have a problem with setting the SSB leval. That was fixed some time ago and
is a available mod for older versions. I have found the noise blanker and
leval control to be very very effective on line noise and other repetitive
types noise. The leval adjust is good to set just to the point of
elminating the noise with out making the receiver suffer disortion from
near by strong signals.......same as any other radio for that matter.
Receive audio is as great as you set the controls and for the speaker that
you use. You would be surprised how many dont change the various receiver
settings for the type of signal that they are listening to. Filters, and
variable settings make a Big difference. I also find the mode differential
receiving using dual speakers or stereo head phones can make a phenomanal
difference in receiving a signal. Use both receivers tuned to the same
signal, but use different filters and modes on each receiver. Your brain
does a great job of sorting out difference's and almost sounds 3D!
The way you choose the radio is up to you. Once you have sorted the
difference's between the radios, choose the one that fits your needs and
wants the best. The latest version of each is a great radio, and most of
the known bugs with each has been fixed. Which one that performes better is
more a question for test instrument comparisions than it is detectable by
the user. I have yet to find a radio on the market that has everything in
it just the way I want it and is bug free...expecially the newer
models....... The D and the MP are mature systems that are great bangs for
the money.
Enjoy your selection, and share with us what you do, and why you chose the
way you did. Good Luck and have enjoyable listening.
