Hi Rob,
You need to key the rig with the TRS jack, not the DIN.? The DIN
heads over to the FM world, and I don't recall it working with the
HF SSB modes, though I could be wrong.? My head was getting rather
flat from the wall it was hitting about then trying (as you) to get
the thing to work.? Again, the rig is trying to be smart, and either
over- or under-doing it.? The "quaint" (now antiquated) model of the
world was using separate, external TNCs for HF and VHF digital, so
they have separate jacks in the back of the rig, and "logic" to try
to figure out where the audio is coming from.
The PTT "signal" is an open-collector style pull-down through about
a 2.2k resistor.? That goes to the Tip of the TRS plug along with
the audio after a 0.1uf DC blocking capacitor.? The TRS "Ring" is
the received audio that goes directly to the audio line-in of the
computer.
Hope this helps,

Thanks Greg & Tom
I think I understand but I still cant get it to work.
I was only wanting to use the 847 on 2m FT8 and was wiring to
the 6pin data socket only.
The soundcard USB Data mode cable I am using is a UD01UN. It
connects to a soundcard and has 3 wires to attach.
Audio Out,?Microphone Input and PTT.
I wired them to the 6 pin din to pins 5, 3, and 1 (I must have
the audio cables the right way as I can RX FT8)
I stopped using CAT for PTT and configured the PTT to use RTS on
the com port the data cable mode.
When I start WSJT the frequency is read (by CAT) and it starts
receiving......if I click on UTNE in wsjt the little red light
comes on in the data cable but the rig doesn't go into Transmit
:-(
I am now wondering whether there is a PTT signal coming out of
the Data cable....... The data cable doesn't show any other
connections to make... just the 3 (Audio Out,?Microphone Input
and PTT.) no GND connection. Should I be able to see something
happening on the PTT wire with my multimeter?
TIA

Rob (getting fed up now!)

For extra credit, try combining both HF and VHF digital modes
(both connectors) to a single Raspberry-Pi based "TNC".? Can be
done.? Not pretty.

Re: FT847 and automatic tuner
Hello again Rolf......yes, I use the interface cable (forget it's number now & its hard to reach - but its the one that MFJ makes for the 939).
The only possible drawback with the 939 is that it has no swr meter. But it does work fine at 100W with both my Hustler vertical and an EFHW.

thank you for your reply. Short question, do you use an interface cable with the FT847 or not ?

Re: FT847 and automatic tuner
Hi Rolf ? I used an LDG YT847 with my FT847.? It was truly plug and play, just connect the RF to the radio.? I worked very well with my HF9V antenna.? I have since sold mine and I don’t think it is manufactured any more but you may be able to find one on ebay? ? I really liked it and only sold it when I switched my radio to an IC7300. ?

Re: FT847 and automatic tuner
Hi Rolf,
I must confess that I haven't read the manual for the 929 until today... The version seems to be 1006 and the age of the unit is unknown to me since I bought it second hand.
The only connections I have made to the 929 is RF in and out, no interface cable to the 847. I operate on all bands 160 to 28 and my multiband vertical isn't the best choice specially on the lower bands.
On some rare occations in the winter when there is heavy snow the 929 can have problem to tune the antenna on 160.
What I like the best about the 929 is the "install and forget" feature that works so well for me.

Re: FT847 and automatic tuner
Hi Nils,
thank you very much for the reply.
I used the MFJ 929 myself many years ago. At that time I had noticed that the firmware version in my device was a very old one and from the selection of transceivers to be connected was not identical to the firmware of the current series.
At that time it was about another transceiver, which was not to be set in the old MFJ 929, but in the new firmware version (other IC). Conversely, it could now also be that the old FT847 is no longer compatible with the newer/actual firmware.
Unfortunately I can't test this by myself because I sold the MFJ929 long time ago.
May I therefore ask which firmware version is in use in your MFJ 929 ?
Thanks for feedback

not exactly the same question??
but I run the TRS connection as my only audio in/out and key line
for HF/VHF/UHF, lots of FT8 during the VHF/UHF contests?
I also run a USB serial thingy and let it trip a small relay which pulls down the PTT line via that 2k resistor or whatever is needed
I run a modded USB sound card (I removed the resistor that puts the DC on the mic line)
never had any trouble, even though it is not supposed to work for VHF/UHF ( I didnt know it wasnt supposed to work when I got my first 847)?
and my second one works the same way
am I confused ?

Hi Steven,
Yeah, I'm not sure what the designers of the 847 were thinking when
it came to digital operation.? It appears that they tried to have
the transmit audio path follow the source of PTT (seems logical), so
the two different connectors on the back (HF, VHF) need to be keyed
on their respective jacks.? The audio from the other sources is
severely muted.? The problem is that when the rig is keyed with CAT,
both of the back jacks are muted.? I guess they figured (somehow)
that CAT would be used with the hand mike?? Odd.
The back jacks also use different keying methods.? The HF TRS port
overloads the Tx audio line (commonly used to key an HT), while the
VHF DIN port has a separate PTT pin.
I was able to use CAT with the 847 a few years ago by using a high
level audio source to override the muting, but that didn't seem to
be a good idea long term.? The 847 does not have VOX, so your
choices are to either use an interface box such as the Signalink, or
configure things to use a serial port modem line.? Right now I'm
using a Raspberry Pi, where, the easiest method is to use Direwolf
TNC and a GPIO pin to drive a transistor buffer for PTT, but not all
digital mode software understands the Pi's GPIO structure, and not
all modes have Pi-compatible versions.
With that intro, here's what I do.? It should be adaptable to other
platforms.? I have a cable rigged up to use a modem line (DTR) from
an FTDI USB serial adapter board to drive the PTT line.? The module
has TTL outputs, so can drive an old TTL inverter chip (7404) to get
the logic sense correct, then to a 2N2222 (as an open collector
buffer) through a resistor.? The transistor's collector then tugs on
the PTT line.? For VHF I use Direwolf as the sound card TNC, , but
anything that can be configured to use DTR for keying should work.
In order to enable the rig for both HF and VHF modes (i.e. both of
the jacks on the back of the rig), I wired up a cable that connects
the audio line on the HF (TRS) port, through an in-line capacitor to
the VHF (DIN) port so that the VHF port doesn't key the HF port.?
Switches either route the transistor's PTT output through a 2k
resistor to the audio line (for HF), or to a separate wire to the
VHF PTT line to the DIN port.? Very confusing to wire up, and prone
to operator failure in use, but once the switches are set right it
seems robust enough.? If you don't need the HF modes, you can skip
the switches and DC-blocking cap, and go direct to the VHF DIN port.
Or just buy a Signalink interface...
Good luck!

I have for sale a Yaesu FT847 HF/6m/2m/70cm all mode transceiver in very good condition. This model does 100 watts on HF and 6 meters, and 50 watts on 2m and 70cm. It also does full duplex for satellite operations and has a built in CW keyer, tone encode, speech processor, DSP noise reduction, bandpass filtering, and notch filtering, and many other features. It is a nice compact size for taking mobile and portable also.
It comes with a photocopy of the manual, the hand mic, and a very short power cord with powerpole connectors on it. It also has the original box and a CAT serial cable with it. It does CAT communications both ways and the power button works fine on it also.
It also has the rare VS-1 voice synthesizer installed, but that needs 1 wire reattached to the wire harness.
I am asking $650 plus shipping and can take paypal/check/MO.

Re: Kenwood KPS-15 DC switching power supply x FT-847
When I first got my 847 I was using a 20 amp power supply. My radio kept shutting down unless I turned the power down. Couldn't figure out what was wrong until it dawned on me that the rig needed more power. I hadn't even bothered?to check the manual because I had used the other power?supply for years with lots of different rigs.? ?
Here is what the specs on the 847 say:?Transmit: 22A @ 100W RF Output
So... it may work as the KPS-15 is rated for 25 amps. 20 amps wasn't enough for mine. If it shuts off on transmit turn the power down and if things are fine it wants more power.
