Tune Function
This function is to transmit continuously for antenna tuning, etc.
If a straight key is connected, simply close the key to transmit.
If a keyer paddle is connected, presss CQ/SET and hold for two seconds, until the letter “S” is
heard, continue to hold until the letter “I” is heard, then continue to hold until the letter “T” is
heard. Then release CQ/SET. Press the DOT paddle to transmit a carrier, the DASH paddle
to stop transmitting. When complete, press CQ/SET briefly to exit.
Transmitting
When transmitting within the amateur bands, the display will show the approximate power
output. The letter “S” is replaced with “F” followed by a series of vertical bars. Each 3 bars
represent approximately one watt of output power. This is the forward power. Above in the
display, the letter “R” is followed by a similar series of bars representing reflected power.
When tuning an antenna or antenna tuner, reflected power should be minimized.
If an attempt is made to transmit on a frequency outside the amateur bands, the HB-1A will
not transmit, and the display will show “TX ERROR” flashing.
