Option Description
ERAS
ERAS is used to delete (erase) a channel. Actually, this action only replaces the user-
modified parameters of the channel with the factory-default parameters, but marks the
channel as not programmed.
The factory-default parameter values are as follows:
• Rx Frequency 15.000.00 MHz
• Tx Frequency 15.000.00 MHz
• SSB Mode USB
• Bandwidth 2.7
• Tx Power MAX
• AGC SLOW.
PWR
Select the channel transmit power level. Four transmit power levels can be selected:
• LOW – 5 W nominal
• MED – 10 W nominal
• HIGH – 15 W nominal
• MAX – 25 W nominal.
FREQ
Select the channel frequency. Micom Pathfinder offers four frequency options:
• SMPX
Simplex Frequency – the same frequency is used for both transmission and
reception.
• DPLX
Duplex Frequency – transmits on one frequency and receives on a different
frequency.
• RXO
Receiving Only Frequency – defines a frequency for reception only.
Transmission on that frequency is disabled. The available frequency range
is 100 kHz to 30 MHz.
• TXO
Transmitting Only Frequency – defines a frequency for transmission only.
You cannot receive on that frequency. The available frequency range is 1.6
to 30 MHz.
BAND
Select the channel operating sideband:
• USB – upper sideband mode
• LSB – lower sideband mode.
MODE
Select the channel radio operating mode:
• SSB – single sideband
• AME – amplitude modulation equivalent
• PLT – single sideband with pilot signal.
AGC
Select the channel Automatic Gain Control mode. Micom Pathfinder offers two AGC
response speeds: SLOW and FAST. You can also turn the AGC OFF completely.
BW
Selects the filter bandwidth.
• 2.1 – 300 to 2100 Hz
• 2.7 – 300 to 2700 Hz
• 3.0 – 300 to 3000 Hz
• 3.3 – 300 to 3300 Hz. Always select this bandwidth for data transmission
• LSM – bandwidth optimized for use with low speed modems (1450 to 1950 Hz)
• CW (Continuous Wave or Morse operation). The bandwidth used in this case is
selected by MENU > PROG > RAD > PRMT > CW.
