[amsat-bb] FT-847 Serial Port Communications

[Gary Schuchardt]

I have a problem involving the 9 pin serial port on the back of my FT-847
Yaesu transceiver. When I try to use a null modem cable between the rig and
my PC on either COM 1 or 2, the rig will not respond to compatible rig
controller (CAT) nor a memory management program. The COM ports have been
tested as well as the use of two different PCs. Neither null modem cable
works. I have tried to use the Menu feature on the FT-847 to match baud rate
between radio and PC COM port. Has anyone had a problem like this with the
Yaesu FT-847? I would appreciate knowing.

Thank you.

I'm not sure it/they are the same, but I had a similar problem with my
FT-857 and found that the voltage that is suppose to be on the data line
connector was missing. If you are using a Yaesu data cable, they usually
derive their power from the mini-din connector on the back. In my case,
a 3 amp surface mounted pico fuse opened up inside the radio. This can
happen if you plug/unplug the data cable with the unit hooked up to
power and especially if it is on.

Again, don't know if this is the case, but it could be a similar
problem. Check for voltage on the data connector if it is suppose to
have any.

Gary,

Do you have a FC-20 auto tuner attached? If so, remove the FC-20 connector,
and turn the rig off and back on. The auto tuner and CAT port use the same
circuitry and are, with some caveats, incompatible.

Some _very_ early models did not have a bi-directional CAT port, which would
certainly cause a problem with a CAT program, and possibly with a cloning
program expecting a bi-directional port.

You seem to have eliminated all the usual cable and port configuration
glitches.

I would like to than you for the information that you provided, as it
corrected the situation to where the memories downloaded so that I could
edit them and upload the new .CSV file. The CAT program works too. I also
appreciate others that offered suggestion too.

I have the first CAT version on my FT-847 this one cannot send any data back to the PC he can only be talk to by the PC. If i use Ham radio
deluxe i am unable to have the program connected to the FT-847 but FT-847 super control is able to connect without any problem!

I always keep the max baud rate at 57600 on the menu and this never seems to be a problem.

After couple of years my FT-847 start to behave anomaly i solved the problem with a master reset.

What program are you using to connect with your 847?

Hi Keith,

Everything is now working. I have been experimenting with programs
developed by Bob Freeth, G4HFQ at http://WWW.g4hfq.co.UK. This includes the
FTBasicMMO (memory management) and FTBCAT to control all the features of my
FT-847 rig. You can contact Bob, at mailto:***@g4hfq.co.UK, if you
have any questions and he will respond very quickly to inquiries. I am
pleased with the software, support and pricing too. The other program that
I tested was the FT-847 SuperCat, but price was a little high for me. The
software is compatible to many of types of transceivers; however, I am only
concerned my current rig. I wanted to wait, until I had a chance to test the
programs before I said anything about what software I was using. I went
ahead and paid a very small fee for one of the program and some others were
free. I have about 36 channels already programmed into my rig memory for
regional UHF and VHF repeaters. Now, I am going to store various
operational and semi-operational satellite frequencies into the FT-847 in
some type of efficient arrangement or ordering to save precious time
changing from one to the other. G4HFQ has various programs that look real
interesting after I get my main object done.

I have installed a new null modem cable and rearrange Com 1 and Com 2 so
that the later can take care of my MixW logging and digital needs. I hope
you find this information helpful. Keep in touch and God Bless. Thanks
again for your help.

Hey Gary,

I've been looking for a long time a replacement FT-847 memory management
program ,since I long ago lost one written by a Frenchman called Edit.

Would you please tell me what program you are using to read and write memory
information to the Yaesu FT-847?

Glad you got your issue with port communication taken care of.
