RTTY and ASCII Operation
RTTY and ASCII operation with the KAM is accomplished through the HF radio port. Several com-
mands and special directives are used to control the operation of the KAM in RTTY or ASCII opera-
tion. The following commands (from the cmd: prompt) will set the defaults for RTTY and ASCII
operation:
ASCBaud
AUtocr
AUTOStrt
CCitt
CRAdd
DIDdle
Echo
FSKinv
INvert
LCRtty
LOwtones
MYAUtost
RBaud
USOs
XMitecho
Entering the RTTY Mode from the Command Mode is accomplished by typing RTTY in response to
the cmd: prompt. This will place the KAM in RTTY operation at the baud rate specified by RBAUD
(default 45) and the display would show the message:
-RTTY 45-
To enter RTTY at another baud rate, you would use the command RTTY n , where n is the desired
baud rate.
To enter the ASCII Mode, the same procedure is followed as for RTTTY operation, except that the
baud rate is specified by the ASCBAUD setting and you type ASCII at the cmd: prompt setting.
The display shows:
-ASCII 110-
Once you have entered the RTTY or ASCII Mode of operation, several directives are activated,
allowing operation in the selected mode. These directives and their use are:
Ctrl-L Send LETTERS shift character in RTTY Mode
Ctrl-N Send FIGURES shift character in RTTY Mode
Ctrl-C S Change shift (170, 425, 850 or MODEM)
Ctrl-C I Invert mark and space signals received from radio
Ctrl-C T Enter transmit mode
Ctrl-C E Enter receive mode when transmit buffer is empty
Ctrl-C R Enter receive mode immediately
Ctrl-C X Leave current mode and return to cmd: prompt (packet)
Ctrl-C n where n is a number (0–9) Changes current baud rate according to the following
chart:
n BAUD RATE WPM
1 45 60
2 50 67
3 57 75
4 75 100
5 100 132
6 110 147
7 150 200
8 200 267
9 300 400
