Having your own waveforms is good, but I was hinting at features, a fully loaded hand held radio can cost upwards of $30k.U.S have their own SDR waveform, ESSOR(7 european countries) and India either have their own waveform or working on it.
We have lots to catch up on even infantry level radios, not talking about special forces radios.
US has more then 20 waveforms, let’s not get into that mess
These days you can get encryption on most of the waveforms so as of now India doesn’t feel the need to have its own waveforms but moving away from DMR is hydra
