MULTI-RECEIVER
|
||||||
|
==============
|
||||||
|
The multi_rx.py app allows an arbitrary number of SDR devices and channels
|
||||||
|
to be defined. Each channel may have one or more plot windows attached.
|
||||||
|
|
||||||
|
Configuration is achieved via a json file (see cfg.json for an example).
|
||||||
|
In this version, channels are automatically assigned to the first device
|
||||||
|
found whose frequency span includes the selected frequency.
|
||||||
|
|
||||||
|
As of this writing (winter, 2017), neither trunking nor P25 P2/TDMA are
|
||||||
|
supported in multi_rx.py. The rx.py app should be used for P25 trunking,
|
||||||
|
for either P1/FDMA or P2/TDMA.
|
||||||
|
|
||||||
|
Below is a summary of the major config file keys:
|
||||||
|
demod_type: 'cqpsk' for qpsk p25 only; 'fsk4' for ysf/dstar/dmr/fsk4 p25
|
||||||
|
filter_type: 'rc' for p25; 'rrc' for dmr and ysf; 'gmsk' for d-star
|
||||||
|
plot: 'fft', 'constellation', 'datascope', 'symbol'
|
||||||
|
[if more than one plot desired, provide a comma-separated list]
|
||||||
|
destination: 'udp://host:port' or 'file://<filename>'
|
||||||
|
name: arbitrary string used to identify channels and devices
|
||||||
|
|
||||||
|
bug: 'fft' and 'constellation' currently mutually exclusive
|
||||||
|
bug: 'gmsk' needs work
|
||||||
|
|
||||||
|
Note: DMR audio for the second time slot is sent on the specified port number
|
||||||
|
plus two. In the example 'udp://127.0.0.1:56122', audio for the first slot
|
||||||
|
would use 56122; and 56124 for the second.
