Jack Pinout
The FT-857 manual hints that the microphone jack is capable of communicating with a personal computer (see
the section on Menu 059, MIC SEL"; this is on page 107 of the FT-857D manual). This allows using the CAT/
Linear" jack on the rear panel for either the external antenna tuner or (what I need it for) to access the 4-bit band
data in Linear" mode. Unfortunately, no other data is givennot even the pinout of the microphone jack(!!). For
any of you interested, the mystery" is solved here.Divining Mic Pinouts
First off, we need the microphone jack pinout. From the schematic (and a couple of guesses), we derive Table
I (see sidebar). Make sure you don"t confuse Pin 1 and Pin 8. Extra functions RXD and TXD are only available
when the microphone mode is set to CAT" via Menu 059.Cable Making
We know this rig is very similar to the FT-817 and it uses the same Yaesu serial cable, so we assume the
circuit proven with the 817 will play with the 857*. That means we require two transistors and three resistors,
plus connectors. For microphone audio, I like using a one-eighth inch phone jack. Push-to-talk uses a phono jack.
The serial data to the PC connects through a standard DB-9 jack (female preferred). The rig end of the cable was
taken from a commercial Ethernet RJ-45 cable with the plastic boot" installed to protect the locking key tab (you
know, the little piece of the connector that really likes to break off). I use short lengths of shielded cable (RG-174
coax works great) for the mic and PTT jacks. Wire the whole thing up like this (Figure 1) with the transistors
inside the DB-9 hood. The shielded wire for mic and PTT exit from the hood as shown in the photograph (above).
Software Problems
Now that the cable is finished doesn"t mean you merely plug and play". But we"re close. You must enable the
extended functionality of the mic jack with Menu 059, MIC SEL". Change it from NOR (normal) to CAT. Menu 019,
CAT RATE" should match your PC application"s serial bit rate.K6XX 2 FT-857 Serial Data From Mic Connector

Now you are free to change the rear panel CAT/Linear jack control, Menu 020, CAT/LIN/TUN", to your choice
of Tuner or Linear, and still have serial communications. Incidentally, my mic jack cable worked fine even though I
left Menu 020 in CAT. The rig saw no conflict even though its serial data sprayed out two different ports.
Operation and an Alternative
With this cable, I now have my FT-857 talking to a logging program through the mic jack and communicating
its active band to my automatic antenna/bandpass filter/amplifier selection interfaces through its CAT/Linear jack
in Linear" mode. When the need arises, I can connect a headset or boom microphone to the mic connector and a
foot switch to the PTT input and use this little mobile rig as if it was a much larger fixed station transceiver.
There was another option considered: use the interface circuit I designed for the FT-817 and decode the BAND
voltage (available on the CAT/Linear jack in CAT mode) into its 4-bit values. However, this solution requires at
least two ICs and four transistors and then only decodes 160m through 10m. Reading the VHF/UHF bands would
require a doubling of circuit complexity. Since a boom-mic headset input was desired anyway, this microphone/
serial interface cable was the simplest and best solution.
