Hi Rob,
Well if receive is working, the sound card is likely ok.? But 2m FT8
is still using SSB, not FM, right?? I believe the DIN connector aims
at the FM world (i.e. for packet radio), so it might be taking audio
from the DIN (because PTT is there), but delivering it to the wrong
place.
Try this...? Put the rig in FM mode, minimum power, and see if
you're getting the AUDIO out (check with an HT).? I bet you do.?
That would confirm that you need to be connecting into the TRS jack.
If so, take the PTT line and run it through a 2.2k resistor to the
Tip of the TRS plug, with the audio going through a small DC
blocking cap (0.1uf or so; not critical).? Ring of the TRS to
Line-in on the audio card.
Good luck!

Still struggling Greg....... I've wired up a 6pin DIN for the
packet socket....as I only want FT8 for 2m.
I now have PTT working via RTS and CAT only reading frequency
not controlling PTT line.
However, I still cant get any TX power out. Its still as if the
audio isnt coming out of sound card.
I've just ordered another USB soundcard to see if that is the
problem
RX works OK.

The PTT from the computer would be measured by an ohmmeter, not a
voltmeter.? It's an open circuit when not active, and a low
resistance when active.? There's a +8v (I think) bias on the Tip of
the TRS that is pulled down by the PTT line.? You need to have the
resistor in series so that the audio can still get through, and the
DC blocking cap so that the 8v bias isn't fed into your computer's
Line-out.
Be sure to have your ohmmeter's leads so that the correct polarity
voltage is applied to the PTT line.? Some (most?) meters put a
positive bias on the Red, some a minus.
Good luck!

Hi Greg,
Thanks again.... I am sure it helps. So I need to use the TRS
socket. Now to find a 2k resistor and a capacitor!!!
Is there anyway of seeing the "signal" on the PTT..... clipping my
multimeter to the PTT wire and GND doesn't show me anything!
Cheers

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

Re: FT847 and automatic tuner

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 ?
