# Configuration file for the AMSAT Multimedia Beacon
# ATTENTION: to configure the beacon go through ALL settings 
# and read the comment for each single setting !!!


# UDP_IPADDRESS is the IP address of the computer where HSmodem is running
# if deactivated (default) then HSmodem runs on the local PC
# tip: nothing to do, leave deactivated because everything runs on one computer
# UDP_IPADDRESS 192.168.1.1

# ----------------------------------------------

# === Pluto-1 serial number ===
# SN of the pluto used as transmitter and narrow band receiver
# check the SN with this command: iio_info -s
# in the beacon this will show two plutos, check which
# one is used as transmitter and enter its SN id here
# tip: you MUST enter the correct SN here after installation of the beacon
PLUTO_TX_NARROWBAND 1044730a199700191f001800f3647c5341

# ----------------------------------------------

# === Pluto-2 serial number ===
# SN of the pluto used as wide band receiver
# check the SN with this command: iio_info -s
# in the beacon this will show two plutos, check which
# one is used as transmitter and enter its SN id here
# tip: you MUST enter the correct SN here after installation of the beacon
PLUTO_WIDEBAND 104473ce6991000809002b0029748935c1

# ----------------------------------------------

# === Beacon TX frequency ===
# this is the transmission frequency of Pluto-1
# this frequency is the CENTER of the beacon spectrum
# enter the 2.4GHz frequency or another frequency in case an upconverter is used
# enter in MHz
# tip: this frequency MUST be set correctly before any operation
TX_FREQ     1290.0815

# ----------------------------------------------

# === narrow band RX freuquency ===
# this is the RX frequency of Pluto-1
# it is the frequency of the lower CW beacon minus 250kHz
# which is 10489.250 MHz minus 390 x LNB-Clock
# Example: if the LNB runs with an external 24 MHz clock
# then enter 10489.250 - 390*24 = 1129.25
# enter in MHz
# tip: this frequency MUST be set correctly before any operation
RX_FREQ     1129.25

# ----------------------------------------------

# === TX power ===
# this is the transmission power setting for Pluto-1 in dBm
# maximum output power: 0
# usually use something between -20 and -5
# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
# tip: if set to a low value then in case of a pluto crash there is a high risk to send
# to QO100 with a high power level !
# so its much better to use a high level here (-5 or 0 dBm) and use an external attenuator
# to reduce the power
# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
TX_GAIN     -5
