cw
From the cmd: prompt, type CW and press return. The RAM Plus enters the CW mode and
sends the following message to your display screen:
-20-20-
This indicates that you are in the CW operating mode, ready to receive CW at 20 words per
minute. If you now tune to a CW signal, your RAM Plus decodes the information for display
on your screen.
To transmit CW, be sure you have the CW Key line from the RAM Plus connected to your HF
radio Key jack. You must have your HF radio in the CW mode with the VOX turned on. Type
CONTROL-C and then the letter T (do not hold the control key while typing the T). This places
the KAM Plus in the transmit mode, but there will be no indication on the KAM Plus or on
your HF radio that you are ready to transmit. Type your message on the keyboard, and the
KAM Plus sends this to your radio by keying the CW Key line. Your radio senses the closing
ofthe key line and transmits the code. Once you have finished typing your message, you must
instruct the RAM Plus to return to the receive mode. To do this, type CONTROL-C followed
by the letter E. The KAM Plus returns to receive mode after all of the data you have typed has
been transmitted.
Some HF radios require you to provide a Push-to-Talk signal to the radio before you can
transmit CW - especially those that do not have VOX capability. If your radio requires this, you
should set the CWPTT command ON allowing the RAM Plus to key the PrT line of your radio.
If you do this, the bargraph on the front ofthe RAM Plus will go dark and the red HF transmit
LED will light whenever you place the KA11 Plus in transmit.
If you would like to operate CW at a different speed (perhaps
10 wpm), you can enter the CW
mode from the command prompt with the speed specified after the command (e.g. CW 10). This
results in the message from the RAM Plus showing:
-10-10-
You are ready to receive and transmit CW at 10 wpm.
When you finish operating CW and want to change to another mode, you must first return
to the Command mode. Type CONTROL-C and then the letter X. This exits the CW mode and
returns to Packet mode, giving you the cmd: prompt from the RAM Plus.
Pactor
When operating this mode using AFSK (mic input), set your HF radio in lower sideband (LSB).
This is general practice in the amateur community for digital communications. You should also
have the VOX disabled since the RAM Plus will key your transmitter. When transmitting, the
amount of power generated by your station can be adjusted with the mic gain control on your
radio. You should set this control just to the point of maximum power output. If your radio
has an ALC indicator, adjust mic gain for minimal indication.
From the cmd: prompt, type PACTOR and press return. The RAM Plus enters the Pactor mode
and sends a message to your display screen that says:
<PACTOR STANDBY>
This indicates that you are in the Pactor operating mode, ready to receive Pactor. If you now
tune to a Pactor signal, your RAM Plus decodes the information and displays it on your screen.
To transmit Pactor FEC, type a CONTROL-C and then the letter T (do not hold the control key
while typing the T). This keys your transmitter, the bargraph on the front ofthe KAM Plus will
go dark, and the red LED at the far left ofthe front panel ofthe KAM Plus lights indicating
you are transmitting. Now type your message on the keyboard. The RAM Plus sends this
message over the radio. Once you have finished typing your message, you must tell the RAM
Plus that you are done, allowing it to return to the receive mode. To do this, type CONTROL-C
