[op25-dev] OP25, SDR, DMR, TX

[Владислав Д.]

Good evening,
Would You kindly to answer a few questions about the OP25 project and how
to organize a transmitter with it using SDR devices (RTL-SDR, LimeSDR)?
In the creation process of DMR-standard transmitter in the GnuRadio
environment, we came across the absence of some necessary blocks: 4FSK
modulator, DMR encoder, packet shaper.
Inside the OP25 project we found a file that contains some functionality of
DMR TX (dv_tx.py), but only in form of code, not as a GRC block.
Could you tell us does this file fully implements the TX-side of the DMR
system and whether there is an analogue of it, in the form of a GRC block
for GnuRadio?

We will be very grateful if you can help us sort this out.

Yours faithfully,
Vladislav.
