Chapter 5 Packet Operation
19: Zero-Crossing FAX 1300/2100
20: Morse 750 Hz.
21: OSCAR-13 Telemetry 400 bps BPSK
cmd:
Any modem from this list may be loaded with the MODEM command. For example, let’s say that you want to
operate 9600 bps VHF packet using the K9NG/G3RUH modem. First, you must switch to Radio Port 2 because this
is the port that has the proper radio connections for 9600 bps Packet operation. To switch to Radio Port 2, type this
at the cmd: prompt:
RAD 2
Your DSP will respond with:
RADIO was 1
RADIO now 2
cmd:
Now you need to load the proper modem for 9600 bps Packet, which is modem number 16. (Use the DIR command
for a list of available modems). To load modem 16, first enter the Command Mode, using
(CTRL - C)
, of the DSP-
232 and then type MODEM 16 as show below:
MODEM 16
(RETURN)
The DSP-232 will respond with the following:
MODem was 13
MODem now 16
cmd:
Note: Do not load modems designed for non-packet modes such as Baudot or Morse when operating
packet. They will not function.
After selecting the specific modem you want to use, you need to set the HBAUD to the proper speed. In the
previous steps, you chose Modem 16, which is by nature a 9600 bps mode. So, you would enter:
HB 9600
The DSP-232 will respond with the following:
HBAUD was 1200
HBAUD now 9600
cmd:
To switch back to Radio Port 1 and operate 1200 bps Packet, type the following:
RAD 1
You DSP will respond with:
RADIO was 1
RADIO now 1
cmd:
The DSP-232 is now on Radio Port 1, however it is still configured for 9600 bps Packet operation -- you want 1200
bps operation. You need to switch to MODEM 13, so type the following:
MODEM 13
The DSP will respond:
MODem was 16
MODem now 13
cmd:
Set the HBAUD to 1200 by typing:
HB 1200
