Generating and transmitting a fake trunking control channel
|
|
===========================================================
|
|
|
|
1. After editing, run generate-tsbks.py which should generate
|
|
a file named "p25.out".
|
|
|
|
2. The tool generates the file packed form; it must be unpacked
|
|
./unpack.py -i p25.out -o sym-cc925.dat
|
|
|
|
3. The unpacked file must be referenced in the json cfg file:
|
|
.
|
|
.
|
|
.
|
|
"source": "symbols:sym-cc925.dat",
|
|
.
|
|
.
|
|
.
|
|
|
|
NOTE: in generate_tsbks.py, keys starting with "iden_up"
|
|
are used to define a channel band plan with bandwidth(bw),
|
|
channel spacing, and starting frequency in Hz; TX offset is in
|
|
MHz.
|
|
|
|
NOTE: with rx.py and multi_tx.py in tandem using the udp option,
|
|
the center frequency must be set in the rx.py trunking TSV
|
|
file equal to the device frequency in the multi_tx config.
|
|
|
|
As always, the control channel and voice channel frequencies
|
|
must fall inside the band defined by the center freqency and
|
|
sampling rate.
