USB and Yaesu FT-857D
This webpage details how to set up
the Signalink USB and Yaesu FT-857D for digital operation.
First, you need the Signalink USB if you plan to do sound card digital
modes. The Signalink USB is an external USB sound card and radio
For the FT-857D, you will need the Signalink 6-pin mini din cable. Set
up the jumpers in the Signalink USB accoring to the guides on their
or follow the picture below...
Before you close up the Signalink USB, do the following:
Behind the RX control, there is a jumper (JP2), place it on both of
Behind the TX control is a jumper (JP3), it should be on one pin only.
Behind the PWR switch (about halfway back on the board) is another
jumper (JP4), place it on both pins.
Close up the Signalink USB, connect it to your computer, and follow the
set up instructions in the manual.
Once you have it set up, connect it to the FT-857D.
To set up the rig, do the following:
For any digital sound card frequency, set the frequency and set the
mode to DIG.
Got to Menu #038, DIG MODE. Set as follows:
For for most modes, set Menu #038 to PSK31-U for USB modes and PSK31-L
for LSB modes.
For RTTY AFSK, you can use the same settings as most modes, or for a
tighter bandwidth, set Menu #038 to RRTY-L or RTTY-U, according to LSB
For any of the above modes, if you change frequencies and modes from a
USB to a LSB mode, you must go into Menu #038 and set it properly.
For sound card packet, you set the rig to PKT using the MODE buttons on
top of the radio.
For modes like SSTV, EasyPAL, and other modes where you need to use
your mic, the best solution is to save the digital frequency
and mode in a memory, then let the next memory
be for voice on the same frequency.
One other note, the FT-857D DSP system DOES affect the rear panel data
jack. If you notice a hole in a waterfall or narrow pattern, check to
see if your DSP Notch (DNF) or DSP Band Pass Filter (DBF) is on.
When you begin to adjust your TX audio levels, use the TX control on
the Signalink USB along with Menu #037 DIG GAIN in the FT-857D.

Hope to "see" you on digital!
