If the rig has had a complete reset the memories may have been wiped
clean. There will be nothing to tune to in the V/M mode.
It has to be re-programmed.
The 897D I have was the same way and I loaded a new RT file and got
everything back plus some.
Works great now.
Or
You have to program it the long, manual way.

OMG,
I have tested my new FT-897D with extremely careful "hearing" on all
bands there was no distortion whatsoever (yes, AM/FM/SSB)!
It's like KC3VO said, it depends mostly on the finals
(transistors/ fet's) used. And there are no two exactly the same FT-
897/FT-857 transceivers alike.
It is so easy to conclude that one transceiver that supposed to have
a bad BIAS is a blue-print for every transceiver of the same
brand/type. Like the FT-817, there were no two identical transceivers
with the same settings (as some found out the hard way).
I would recommend to NOT fiddle with the BIAS until you are 100% sure
that there IS distortion in the modulation on a particular band(s)
AND you are sure the finals are those according to the service manual
default settings.

Jerry:
I have been using my 897D with a Heil GM-V mic and the Heil footswitch
they offer. When I purchased the mic I bought the Heil adapter to fit
the type of radio that I have.  It works Great!  I love the Heil
footswitch.
You can also run other studio mics but you will need to interface with
a small mixer before the radio to get proper impedence.  I use a
Behringer 1202FX to use my Sure SM58 with the radio.
Hope that helps and have lots of fun with the new rig!

Hi everyone,
Just as the title subject of the e-mail says, I'm trying to choose
between these two radios.
  I have no radio at all at present so whatever I get will be my main rig
for awhile. These are the only two radios within my reach budget wise at
present. I'm just a casual operator, I'm not a serious contester
although I do "play" in them quite often just for fun.
  My main reason for interest in the 897D is the fact that it covers HF
plus 2m and 70cm.
  Up until recently I operated on satellites  and I might buy the 897D
with an eye on eventually getting a second one and having a two radio
full duplex sat station. I really have no interest in 2m or 70cm other
than that. I cannot afford something such as a TS-2000 or used FT847 or
I would go that route.
  I feel that the 450 probably has a better receiver and more features
for the HF operator than the 897D so I have been toying with the idea of
giving up on the sats altogether and going strictly HF with it. I just
can't decide. I know a lot of you use the 897D as a portable or a second
rig and would not consider it in the role of a "main" station rig so
this does give me pause about using it in that manner. Any opinions or
suggestions would be most welcome.
Tnx and 73,
Michael, W4HIJ

Yeah, Joe, I had the same problem.  I also notified them.  But if you
will look in our Files under "BHI DSP module on FT-897D" you will
find a pdf and two sound file from KB5LDD.  Thanks, KB5LDD!

Yes, this is Audio Freq DSP.  It has four levels accessed by pressing
a single button, which also turns it on and off.  It works better
than I imagined.  It is money well spent.  I'm a very happy customer.

I'll post a photo of mounting the button tomorrow.

I faced the same decision about six months ago and was persuaded to go
with the 897--in part because I could also use it portable. I live in
a high rise New York City building and working HF always was going to
be problematical. My fall back is taking the rig to Central Park and
operating by battery.

The other issues is a belief offered by some that Yaesu had tried to
pack too much into the 450--and the cut corners to get the price down.
The turning knob is very small compared with the 897 and you can't
elevate the 450 as you can with the 897.

While the 897 can work 2 meters and 440, I still use my own Yaesu 7800
for those bands, if only because the 7800 can be controlled from the
mic and a comparable mic on the 897 would be an extra cost option.

Still, I don't think you can go wrong with either. We had an
expression in my days as a competition pistol shooter than a given gun
could shoot better than the shooter could hold. In other words, the
gun was capable of better accuracy than a shooter, giver hand shakes,
etc. could actually achieve. Either radio is capable of delivering
better results than the average operator can actually achieve.

The display of the 450 makes a big difference.  There  is nothing like
being able to look at all the invormation at the same time instead of
going through menus.  I found a you tube video that you can look at.

I've posted, in my folder AE5JU in the photos section, a photo of how I
mounted the BHI DSP control button.

The A/B battery rocker switch was removed, simply unplugged from the
board below it.  A pice of textured ABS sheet plastic was glued in
place and the switch/LED mounted there with Aleene's 7800 adhesive.

Being they are approx. same in price, you might go to your local ham shop and
listen to both and play with each. Your right the 897D does cover a few more
bands, but if you don't care about uhf/vhf no big problem. I use the 897D as
base with a AT-100 Pro auto/tuner. Have not actually compared the receive on the
two so can't say which one is best. Regardless of your choice, I would not get
the ATU-450 auto tuner with it. LDG makes auto/tuners for about the same price
and they cover more freqs. Good luck. Read some reviews on E-ham that might help
you with your choice.

I have never seen an FT897D transceiver with anything but 2SC5125
devices in the PA stage. Has anyone actually encountered one? The only
way to be sure is to pull the bottom cover off and look. The devices
are labeled. I realize that Mitsubishi no longer makes them, but
unlike the IC-756 Pro III, which also used the 2SC5125, I have not
heard of any new PA designs for the 857/897 line. Doesn't mean it
didn't happen though. There were rumors that Yaesu might move to the
Toshiba 2SC2782 which is a common replacement. I would love to know if
the 2SC5125 is no longer used in current production units.

The change in driver devices from the 2SK2975 to the Mitsubishi
RD07MVS1 FET devices back about 5 years ago is very well documented,
and did change the setup parameters. It also thankfully had a very
positive effect on the reliability of the 857/897 rigs.

Regarding the idling current parameters, the bias settings should not
vary from unit to unit. Unlike the service menu values, which are
unique to each radio due to the range of combined device tolerances,
the pre-driver, driver, exciter, and final stages are not unique and
need to be running linear to produce a clean signal. The service
manual values offered by Yaesu are within the range that puts the
devices into linear operation. Sadly, it appears that these settings
drift over time, and from what I have seen, they always drift towards
cut-off. So, if your rig does not exhibit distortion today, it may
tomorrow. As licensed amateurs, we are totally responsible for
assuring that our equipment is operating correctly, so if you start
getting reports that you sound gritty and distorted, it would be wise
to check your driver and PA idling current.

Bob's caveat about not adjusting anything until you know what is
inside the radio is very wise advice. If you go to the trouble of
doing the bias adjustments, make sure the settings you use apply to
your radio.

If Mitsubishi no longer makes them what happens if I blow the finals?

The 2SC5125 is very rugged and the extremely conservative way they are
set up in the 857/897 final stage pretty much assures that failures
will not be a common event. Yaesu has indicated to those who have
inquired that they have plenty of devices stockpiled in their
inventory for repair purposes. If that is not reassuring enough, the
Toshiba 2SC2782 device has the same power rating, package design, and
higher dissipation ratings. It is widely available (even in matched
pairs) and is considered a direct replacement.

I was looking at W4RT and saw there are two types of CW filters. The
300HZ filter is advertised for contesting and PSK.  Would this also be
a good filter for everyday ragchewing or should I go with the 500HZ
filter?

Is the 2.3KHZ filter a good option for SSB?  I think there are only 2
slots in the radio and you can only have 1 CW and 1 SSB filter, each.

Any input is appreciated.

Thanks,
Kyle

Had a QSO with a guy that said he had an FT-101 and blew the finals in
it and was told that they are no longer made.

Yup, it's been a long time since 6JS6C sweep tubes have been made. But
then again, I don't think there's too much demand since (most)
televisions today are solid state.

Kyle -

I would go for a good quality 500 Hz filter (INRAD) and utilize the
built-in DSP features of the rig when more filtering is required.  There
are certainly enough features in the rig to do more filtering.

It all depends on what you need.

Ok, so I got the name of the rig wrong.  I remember that it is a yaesu
and has solid state finals.  I think MRF something.  it's an all band
unit and maybe 8 to 12 years old as I recall.  He was topld by Yaesu
that they couldn't get the final transistors any more.

      I just recently had a Yeasu FT-101EE that takes the same tube final and I
found tubes on one of the tube sites that were made in Russia that worked in the
ft-101. However, a modification needed to be done to the final section of the
radio to make them work. I did the mod which wasn't to time consuming and the
only thing I found was that it had a little less final output, but according to
reports the audio was 5,9. Hope, this helps the guy out some as it would be
assamed for such an excellant oldie to become a boat anchor.73' from Elkton,Md

Yup, it's been a long time since 6JS6C sweep tubes have been made. But
then again, I don't think there's too much demand since (most)
televisions today are solid state.

If you do not know the answer you probably do not need the filter at
this time.
It is best to operated the radio and get the proper filter if and when
you may need it.
If you do not have any problems you do not need it.
The stock SSB filter is OK as is.
Adding the 500hz filter is OK for normal CW use
A narrow one is not needed unless you are a dedicated contester.

Yes Jim, 
      I would guess that it was probably the MRF 477, none of those good rf
finals are available anymore and that's a real shame as there are still allot of
those oldies out their that requir those finals and are still going strong. 
P.S:
     Don't feel bad I forget things all the time & it seems the older I get the
harder it becomes to remember, hi hi... its only due to so much technical
knowledge in my head there's no room for trivial things. hi,hi...73' from

Ok, so I got the name of the rig wrong. I remember that it is a yaesu
and has solid state finals. I think MRF something. it's an all band
unit and maybe 8 to 12 years old as I recall. He was topld by Yaesu
that they couldn't get the final transistors any more.

I've just posted sound samples of my results with the BHI DSP.

Lack of a DSP audio filter is big draw back and hard on your ears after
a while.   This filter seems like a good addition, however, did you have
to give up the battery switch?
