BK Use Break On/Off to toggle between break mode on and off. The keyer responds with the
current mode "ON" or "OFF". Break mode allows you to insert code into a message that is
playing. Press a dot or dash to break into a message. The keyer will stop the current memory
message. Begin sending code. After you finish sending code, press any message button to
resume playing the message where you interrupted it. Press Menu to clear a message.
C# Where #=0-9. Use character break to customize the length of the intercharacter spacing. A
standard character break is 3 dot lengths long. The number following the C is the number of
extra dot lengths added to a character break.
FA Use Farnsworth mode to toggle between Farnsworth mode on and off. Farnsworth mode works
with the random code generator. It sets the code character speed to 18 words per minute while
keeping the overall word speed at the defined setting. If the keyer is set to 5 WPM in
Farnsworth mode, the keyer will send 18 WPM characters while inserting extra word break and
intercharacter timing to maintain an effective speed of 5 WPM. At speeds above 18 WPM the
keyer reverts to normal timing. This feature allows a user to associate Morse characters with
their sound rather than by counting dots and dashes.
KC## ##=00-15 sets a keying compensation value. Some radios have a key delay of 5 mS or more.
By entering KCO5, the keyer will add 5 mS to the dots and dashes. This eliminates the
problems with a keying delay
R# Where #=1-8. Use Random Number to customize the Random Code Generator. The keyer
will play "OK" after your command has been entered.
