Quick testing of RadioTone RT5 Zello PTT mobile radio (it’s dedicated to use in car but in mine application will be a base station).
First impression is good, very loud and clear audio , remind me very much DMR Motorola DM4600 especial round mic connector plug… and i like it 🙂
Keep in mind this is not a DMR radio, just android smartphone.

Of course i will go for 50V… higher the better.
Another example why not trust in Chinese stuff 😉
