--cc "<osmo-cc arg>" [--cc ...]

Pass arguments to Osmo-CC endpoint. Use '-cc help' for description.

--no-l16

-l --loopback <type>

Loopback test: 1 = internal | 2 = external | 3 = echo

-r --realtime <prio>

Set prio: 0 to disable, 99 for maximum (default = 0)

--fast-math

Use fast math approximation for slow CPU / ARM based systems.

--write-rx-wave <file>

Write received audio to given wave file.

--write-tx-wave <file>

Write transmitted audio to given wave file.

--read-rx-wave <file>

Replace received audio by given wave file.

--read-tx-wave <file>

Replace transmitted audio by given wave file.

--limesdr

Auto-select several required options for LimeSDR

--limesdr-mini

Auto-select several required options for LimeSDR Mini

SDR options:¶

--sdr-soapy

Force SoapySDR driver

--sdr-channel <channel #>

Give channel number for multi channel SDR device (default = 0)

--sdr-device-args <args>

--sdr-stream-args <args>

--sdr-tune-args <args>

Optional SDR device arguments, separated by comma e.g. --sdr-device-args <key>=<value>[,<key>=<value>[,...]]

--sdr-samplerate <samplerate>

Sample rate to use with SDR. By default it equals the regular sample rate.

--sdr-lo-offset <Hz>

Give frequency offset in Hz to move the local oscillator away from the target frequency. (default = -1000000)

--sdr-bandwidth <bandwidth>

Give IF filter bandwidth to use. If not, sample rate is used.

--sdr-rx-antenna <name>

SDR device's RX antenna name, use 'list' to get a list

--sdr-tx-antenna <name>

SDR device's TX antenna name, use 'list' to get a list

--sdr-clock-source <name>

SDR device's clock sourc name, use 'list' to get a list

--sdr-rx-gain <gain>

SDR device's RX gain in dB (default = 0.0)

--sdr-tx-gain <gain>

SDR device's TX gain in dB (default = 0.0)

--write-iq-rx-wave <file>

Write received IQ data to given wave file.

--write-iq-tx-wave <file>

--read-iq-rx-wave <file>

Replace received IQ data by given wave file.

--read-iq-tx-wave <file>

Replace transmitted IQ data by given wave file.

--sdr-swap-links

Swap RX and TX frequencies for loopback tests over the air.

--sdr-timestamps 1 | 0

Use TX timestamps on UHD device. (default = 1)

Network specific options:¶

-F --fm

Use frequency modulation instead of amplitude modulation. The carrier frequency will be 7.5 KHz above/below the actual frequency. This ensures that the change in frequency results as a change in amplitude at the demodulator of the receiver.

-T --tx

Transmit Eurosignal on given channel, to page a receiver. (default)

-R --rx

Receive Eurosignal on given channel, so we are the receiver. If none of the options -T nor -R is given, only transmitter is enabled.

-I --id <id> [-I ...]

Give one or more IDs to allow only the given IDs to be transmitted and received. This option can be repeated many times. If this option is not specified, any ID is allowed to transmit. Also, any given ID will cause a beep when received. This requires call device (sound card) to be defined or MNCC interface. (The caller ID will be the received pager ID. The called number will be '1' for the first ID given, '2' for scond, ...)

-D --degraded

Play the announcement that the system is degraded due to failure of one or more transmitters. If the caller hangs up during or right after the announcement, no paging is performed.

-S --scan <from> <to>

Scan through given IDs once (no repetition). This can be useful to find the ID of a vintage receiver. Note that scanning all IDs from 000000 through 999999 would take almost 10 Days.

--random

Repeat some pseudo random IDs, to make the transmitted signal sound authentic and as it would handle many calls. It will still be possible to page a recevier.

--repeat <num>

Repead paging ID <num> times when transmitting. (default = 4)

station_id: Give 6 digits of station ID,

so you don't need to enter it for every start of this application. Give 6 digits for number. You may use '0279xxxxxx' as prefix. You may use '+49279xxxxxx' as prefix. You may use '0509xxxxxx' as prefix. You may use '+49509xxxxxx' as prefix. You may use '0709xxxxxx' as prefix. You may use '+49709xxxxxx' as prefix.

Press digits '0'..'9' and then 'd' key to dial towards mobile station. Press 'h' key to hangup. Press 'w' key to toggle display of RX wave form. Press 'c' key to toggle display of channel status. Press 'm' key to toggle display of measurement value. Press 'q' key to toggle display of RX I/Q vector. Press 's' key to toggle display of RX spectrum. Press 'b' key to remove DC level.
