I use my connected FT-897 to my PC through a cable CAT with interfeice USB.
I already used several programs of CAT as Ham Radiate of it Shows off other, but
none of them gets to arm bearer of my FT-897. Will it be that is some
configuration that I am not getting to do? If somebody please knows about
something it helps me.
Thankful

AHhhhhhhh, that makes SO much sense!!  Our last holiday away, I had
the 897 (with the AT bolted to the side) mounted face-up against the
cargo barrier in the station wagon, and with a bag sitting slightly
above it, the tune button was getting tapped when we went over decent
bumps.. - the next time the OpenTracker would make the rig transmit,
the body control module would go nuts!  When I finally figured out why
my cruise control kept turning off for ~4 seconds at a time I moved
the gear in the back around, and re-tuned (which took all of about
half a second), and the problem went away..

And that would explain why it appears to not have memories of
previously-tuned frequencies - to get the LED to light, you have to
hold it in for 2 seconds or so.. - pressing it for a second or so and
releasing, makes it look like it tuned, but it only transmits for
about a half a second - I figured it was just doing something weird
because I hadn't held the tune button in for long enough..
Thankyou!!  WIll make using the AT so much easier ;)

There's no place on the radio to mount the clip. It's for mobile use or
for hanging the mic on the bench.

I've come to the conclusion that Yaesu are very ham-centric and almost
having a subtle joke by not mentioning the mic.clip in the manual, as
they know that every ham will want the clip where they prefer it -
fixed to the ham bench, strapped round your leg, yes on the rig
itself, hung from the ceiling of your RV etc etc! It really is, as a
ham, up to your own preference :)

I have an FT-897. When the Blue "Power" button is pushed the radio will come on
for 3 seconds then go back off. The radio will NOT power back up until the power
source, (it does not matter if it is on batteries or the 100 Factory power
supply) is disconnected and reconnected. This ALL that it will do. Any
suggestions would be appreciated.

Buddy . . .

The radio will shut down if . . .

1)  The SWR is too high

2)  The rig is on battery power and they are not fully charged

3)  Other conditions (high voltage, shorted cables, no antenna
connected, etc.) exist that tell the radio to protect itself.

Kent, have you had the radio shutdown when the SWR was too high? This is
interesting as on my FT897, when there was a dead short (braid touching
inner wire) across the N socket (VHF/UHF), it just showed HSWR when I
transmitted but didn't shut down....

Perhaps older/newer versions behave differently?

BTW, the dead short doesn't seemed to have harmed the finals.... :)

Your radio probably saved itself by protecting the finals.

If there is sufficient RF in the shack that it affects several boards
and circuits, including the power supply circuit, the radio will indeed
shut itself down, just as it does with low battery voltage.  It's seeing
the same condition regardless of the cause.

Too many new hams think that if an antenna can be matched with an ATU
such that the rig is happy, then they're home free.  Not so, for two
reasons:  1) RF in the shack can do strange and wondrous things to
circuit boards, components, controls, and displays; and 2) low to no
radiation efficiency from the antenna can turn a 100 watt radio into a
QRP rig real quickly.

Too many new HF hams with nothing but VHF/UHF experience think the
dynamics are the same regardless of frequency.  They soon learn otherwise.

I want to connect my 897 and my antenna tuner to a copper ground bar recently
given to me.  The bar is rectangular in shape, about 10" X 3" with two rows of
holes going across it.  Can I use typical galvanized bolts and wing nuts to
connect my ground wires to the copper plate, or do I need something different? 
Any chance I can push the wire through the hole and just twist it?  Thank you in
advance , Doug Yaeger, KB1QJK

use only the same type of metal in the wire and buss barotherwise it will set up

DE N7UVL,
You might want to consider switching the Tuner in and
out of the Transmission Line path. So it will not interfere
with out of Band Receiving. Put the switch & cables in place
with your existing Tuner to see how receiving is affected
and how you like it. If your existing Tuner has a pass
through feature switch, you already have everything you
need for an initial test. Then you can decide if you want to
go ahead and put the switch & cables in place to do the
same thing with an autotuner. Right of hand, I cannot
think of any autotuners that have a pass through feature./ga

DE N7UVL,
I guess I'd better amplify my remarks below, so you wont
"kill your Tuner or 897.
-There would be to ways to accomplish the remarks below.
One would be with two switches, but you'd have to
remember to switch both.
-The other way would be to make sure you are "Not" using
a switch that grounds the unused ports. Place a "T" connector
on the transmission line side of the Tuner. 1 side to the Tuner;
1 side to a port on the switch; and 1 side to the transmission line.
On the Radio side of the Tuner, place a cable to the other
antenna connector on the switch, and finally a cable from the
switch to the Radio.
-When using the switch on the "Tuner" side position, the
"short" extra cable from the "T" to an ungrounded port on
the switch will just act like a stub, that should only have
a minor effect if any on the transmission through the Tuner.
-Again, do not use a switch that grounds the unused/un-switched
ports. You don't want to put your Tuner output to ground
when its not switched into place.
-Finally, there are electronic switching methods that can
accomplish the same thing. Originally used on vintage rigs
for switching a tuner in and out during key down. Most of
those circuits were usually designed to work with a "keyed"
line from the transmitter though. Some Autotuners may
already have this feature, but needs to be verified./ga

As I think to use MD-100a8x with FT-897D  does'not have much sence:
With FT-897D's HF frequecy width in SSB close to 2khz it will make almost NO
difference with ANY KIND of mikes.Only worth to replace the standart dinamic
capsule inside the MH-31 to electret one.Only this will make proper effect in
SSB transmitted audio.
If to install INRAD 2900khz SSB filter-the Radio(897D) becomes "a little
IC-756pro3" Then any expensive mikes will begin to work...

1 The AT897 autotuner does have a bypass feature by just pressing the tune
button in a certain way.
2 Down to the more basic question.  If you are thinking of attempting to use the
autotuner to match the antenna to the received frequency for better reception it
will NOT work unless you are listening to something within the amateur bands. 
The only way for an autotuner to match the antenna is with a transmission from
your tranceiver.  If you are outside the amateur bands either the 897 wont allow
the transmission, or if you have modified it fir wideband it is illegal to make
that transmission.

All of the LDG tuners will let you push the tune button once quickly to put the
tuner in bypass.

Doug,

Bolt it and make sure the connections are tight and clean.
Run a low Inductance and Resistance conductor in as straight a line as possible
to a GOOD earth ground.
Twisted connections??? is asking for PROBLEMS.

For the ground from my 897 to my car's body I used UR67 braid,
flattened and of course bolted, but it's only about six inches long.
Methinks something wider for a longer run like yours.

Also, if you have to use connectors in the ground lead, use the biggest
and best CRIMP connectors appropriate for the size of cable. Do not rely
on soldered connectors. If you are using strip conductors for grounding,
you can join strips by lap joints, through bolted by three bolts of the
same material, e.g. copper.

If you are running any length of ground lead, do not run it parallel
and/or in close proximity to other wiring.

I examined a church tower that had received a direct strike. There was a
little damage to the top of the external 3" by 1/2" lighning conductor,
but otherwise the lightning precautions survived their purpose. The church
had been hit several times in the past.

However, since the previous strike, somebody had installed some lights and
a power point in the belfry, using screw-barrel steel conduit. The conduit
ran inside the stone and brick tower, parallel to and about 2ft from the
lightning conductor and formed a closed loop. Whe the tower was hit the
screw-barrel was blown completely off the wall!

FT-897D is extremly simple-may be of that reason it works not so good.

Dennis, a properly crimped connector is designed to survive a pull test
which is a significant part of the breaking strain of the wire. Soldered
connectors are more likely to corrode.

autotuners are a good bargain now. i just heard the bypass button is tricky if i
want to hear broadcast SW. maybe keep the old tuner in case it needs T
connector.
thanks

Dennis

In fact, a properly crimped connection is usually better than a soldered
one.

Soldering often provides a solid point where the solder has wicked up the
wire making it stiff and more likely to snap off with any bending movement
or long term vibration.

Most commercial installations do rely on crimp rather than solder.

Greetings fellow hams,


I want to pick your brains again today :)

1.  If you could choose a city apartment rental floor from which to
work DX (and local) on all HF ham bands to include 160m (and VHF &
UHF), which floor would you choose?  This includes operating from
indoors, and from a balcony or fire escape.  Let's assume for
simplicity's sake that any floor you choose has a clear line of sight
to the horizon in at least one cardinal direction.  (The apartment
building isn't surrounded on all sides by taller buildings.)

2.  Which floor would be the lowest floor you would consider?

3.  Is there such a thing as a floor that's too high for good
radiowave propagation?  (Let's be reasonable.  There is no Tower of
Babel Apartment Complex in this city ;)

4.  What if you could choose any rooftop from which to operate from
time to time?  How high would your rooftop be?  How many stories?

5.  What kind(s) of antennas not permanently installed would you use?


Thanks in advance.


73,
Frank

Gary,

Please read the questions.  If you could choose ANY roof, how high
would it be?  What if you had to operate from within an apartment or
from a balcony or fire escape?  Thanks.


73,
Frank
