Make any necessary jumpering on the P4 jumper block as described later in this manual under
VIRTUAL COM PORT SERIAL SELECT – P4.
Unlike RTTY AFSK which is normally operated in LSB you will have to operate your radio in RTTY
mode to enable FSK keying input.
Amateur radio FSK keying is at 45 baud and modern USB to serial converters do not support this low
baud rate or 5 bit operation. Therefore the only program available for FSK via a USB interface is
MMTTY used with the EXTFSK extension. This program would normally be configured to use RTS
for PTT and DTR for FSK, like CW. Since the RIGblaster duo has two serial emulators you may
configure the serial jumper block so that one is for CW and the other for RTTY FSK.
RIG CONTROL CABLING AND SETUP
RIG Control cabling and jumpering differs depending on the radio manufacturer.
Most ICOM and TenTec (with CI-V) use a single bi-directional conductor and thus require a patch cord
that is stereo on one end and mono on the other (tip and ring on the RIGblaster duo end and both of
those wires connected together to tip on the radio end).
With a Yaesu it is a little more complicated. The Yaesu CAT system uses three wires and they have
different connectors and pin wiring arrangements for different models. Older Yaesu radios require the
rig control TTL (5 volt) level converter built into the
RIGblaster duo
. West Mountain Radio has
ready-made CI-V and CAT accessory cables available for various TTL level controlled radios.
There are two rig control outputs; “RIG CTL A” on the virtual COM port A and “RIG CTL B” on
virtual COM port B so that you may independently control two different radios.
To use rig control connect the proper cable between the corresponding rig control outputs and each
radio. You must then configure your rig control software, and possibly radio, for the correct COM port
number as noted in the Windows Device Manager. An exact match for radio make and model, baud
rate, parity, stop bits for proper communication is essential. NOTE: if any one item is incorrect you will
have absolutely no rig control function.
