Step 2b: Configure the PC and Radio for RTTY FSK Operation
Presently, to our knowledge the only RTTY software that works with the
RIGblaster Plus II
or any USB-to-serial interface is
MMTTY
, and that
only by using the author’s EXTFSK extension. The reason is that USB-
to-serial interfaces will not go down to 45 baud.
Follow the MMTTY Help files for setting up the program using the
EXTFSK extension to use the correct COM port with PTT on RTS and
FSK keying on DTR.
Once configured, transmit with MMTTY and watch the PTT and CW
LEDs. The PTT LED should be on steadily and the CW LED should
flicker with the RTTY. Confirm with the radio’s monitor that the FSK
output sounds like RTTY.
You will also have to make sure that your mark and space tones are
correct by setting the radio and/or the software so that transmit and
receive mark and space tones are correct. The only easy way to do
this is on the air.
Step 3b: Have Fun Working DX
You are on the air with FSK RTTY.
RIG CONTROL CAT/CIV, INSTALLATION AND SETUP
(READ CAREFULLY and PROCEED IN ORDER)
Step 1c: Connecting a CAT or CIV interface
The
RIGblaster Plus II
has a built-in USB-to-Serial converter with TTL (5
volt logic) output. It may be used with any radio (CAT or CI-V controlled)
that requires an RS232 to TTL level converter. This includes most Icom,
Ten Tec (CI-V) and smaller or newer Yaesu (CAT) radios.
NOTE:
If your radio has a DB-9/RS-232 rig control jack, you
do not need,
nor can you use, the TTL level rig control interface inside the
RIGblaster
Plus II
. These radios require a direct connection to a PC’s RS-232 COM
port. If your PC has a DB-9/RS-232 COM port, you may purchase a DB-9
cable; if the PC does not have RS-232, a USB-to-Serial interface cable is
also available for purchase. If you do wish to use the rig control feature
of this
RIGblaster Plus II
, you may order a pre-wired cable from West
Mountain Radio for rig control.
