KS: Get/Set Keyer speed
Set: Sets the Keyer speed to the specified number of words per minute
Get: Gets the current Keyer speed setting (in words per minute)
KY: Get/Set message for immediate sending
Set: Initiates a CW message transmission at the current keying speed. The format of the command
is KY followed by a space, followed by the message to be sent, followed by a semicolon
termination character. For example command
KY HELLO;
will initiate CW transmission of the text “HELLO”.
Get: Returns:
KY0; if message sending is in progress and the transmit text buffer is not more than 75% full
KY1; if message sending is in progress and the transmit text buffer is more than 75% full
KY2; if no message is being sent, therefore the transmit text buffer is emtpy
?; if the attempted message would overflow the transmit buffer; in this case it is canceled
Note: The KY transmit text buffer is 80 characters long. It is a circular buffer. It is acceptable to send
new messages with KY before the message sending is complete, they are simply appended to
the transmit buffer. You may not send a message that would overflow the buffer, if attempted
the message will simply be ignored and error code ?; returned.
MD: Get operating mode
Get: Always returns 3 (CW)
OM: Get the radio’s model number
Get: Returns the radio’s model number. For QCX+ this is QC so the result is simply OMQC;
