DFE Mode:
“DFE” is annunciated when mode is activated a dash, [ - ], is displayed on LED
This mode allows you to enter a desired operating frequency using the paddle. This can be any frequency within
the upper and lower band edges currently in use. Simply use the paddle to enter the frequency numbers in Morse,
starting with the 100 kHz digit and ending with the 100 Hz digit (four numbers total). The LED display will
display the number which has been entered and the side tone will sound a beep. If a number is miss sent, a “?”
will be annunciated and that digit must be re-entered. When four digits have been entered, the new frequency will
be read out via Morse and the display, then the rig will re-tune to that frequency. If the frequency entered is
beyond the tuning limits, DFE mode will simply terminate and the frequency will remain where it was.
NOTE:

DFE mode is not available if the rig is in Straight key mode.

DFE mode is not available when RIT is active.

DFE mode can be escaped by clicking the < Fn > switch at anytime before all 4 digits have been entered.

Some “Cut numbers” can be used. These are “T” = 0, “A” = 1, “U” = 2 “V” = 3, “N” = 9.
Tune Mode:
“T” is annunciated when mode is activated, “t” (of sorts) is shown on display
NOTE : Tune mode is not available if the rig is in Straight key mode.
This mode allows you to toggle the transmitter on and off using the paddle. This makes it easier to adjust a
small antenna tuner if two hands are required to operate it (One to hold it in place and one to turn knobs).
NOTE: If the supply voltage exceeds 10.0 volts, the power output is automatically reduced. This reduces the risk
of PA FET damage if the SWR becomes excessive while adjusting an antenna tuner or checking SWR into an unknown
load. Power output starts at a few 100 mw and it takes a few seconds for the power to ramp up to about 2 watts.
If full power output is desired, for say checking power output into a 50 ohm load (dummy or antenna) with a
supply voltage greater then 10.0 Volts, put the rig into straight key mode by holding closed the Dash paddle
while tuning power on. Reset to paddle mode when done by cycling the power off and back on again.

If a constant carrier is not needed, it is better to send a string of Dots then use Tune mode for
adjusting a tuner.

Toggle transmitter on: Tap the LEFT (DOT) paddle.

Toggle transmitter off: Tap RIGHT (DASH) paddle.

Exit Tune mode: Click Fn switch, “E” annunciated.
Battery Voltage:
This mode reads the input voltage to the board and then displays it on the LED display and annunciated in Morse.
The letter “B” is sent before the digits during Morse annunciate. A dash [-] is used to indicate the decimal
point since the display decimal point is always on as a power on indicator.
Low battery voltage warning:
A low battery voltage warning can be programmed to advise you it's time to go QRT before you damage your battery.
This is important if you are using Li-ion batteries. The letter “L” will be displayed on the LED readout when the
battery voltage drops below the set point. The set point voltage is entered using the User settings function
described later. The factory default voltage is set to 5.5V as this is the absolute minimum voltage the MTR will
function at.
Fn switch only selected functions:

Frequency

Keyer code speed (S)

keyer memory entry (M)

User preference settings (P)
With the exception of Frequency, click and hold closed the Fn switch until the letter on the 7 segment display
appears and the Morse letter identifying the desired function has been annunciated by the side tone, then release
the switch. The switch must be released before the next letter in the Fn sequence is annunciated to select the
desired function.
