tx_sdr
tool for transmitting data to SDRs,
based on rtl_sdr
from librtlsdr,
and rx_sdr
from rx_tools,
using the SoapySDR vendor-neutral SDR support library,
intended to support a wide range of TX-capable devices.
Mostly untested pre-release quality code, YMMV.
Install SoapySDR, then run:
mkdir build ; cd build
cmake ..
make
After building, these binaries should then be available at the build directory:
tx_sdr
- transmits raw I/Q datapulse_gen
- create I/Q data file from pulse textcode_gen
- create I/Q data file from code textAlso some test and example programs:
encode_ascii
- simple CLI to test ASCII encodingencode_dmc
- simple CLI to test DMC encodingencode_hex
- simple CLI to test HEX encodingencode_imc
- simple CLI to test IMC encodingencode_mc
- simple CLI to test MC encodingcode_dump
- an example how to parse and process code textexample_gen
- an example how to parse code text programmaticallyCU4

- 64-bit /channel, double I/Q dataFor CU8
(CU4
) the value range is 0
to 0xff
(0xf
) with uniform distribution,
i.e. a bias of 127.5
(7.5
).
This matches the output format of the RTL-SDR receivers.
For CS8
(CS4
) the value range is -127
to 127
(-7
to 7
) with uniform distribution,
i.e. a smaller dynamic range than the unsigned formats, but without bias.
Tools to be added soon will implement modulation and encoding for:

, ASK
, AM
FSK
, 4-FSK
, GFSK
, FM

Currently tested with a LimeSDR-USB, LimeSDR-mini, and LimeNET Micro, but supporting all devices supported by SoapySDR is the goal. Experimental, use at your own risk, but bug reports and patches are welcome.
