    Default Are Motorola TETRA & TRBO mics interchangeable?

    Current Motorola TETRA & TRBO desk mics & fist mics look identical externally and have the same round black connector- the user guides even cover both models. What I don't know is if there is any difference in characteristics or if they are interchangeable. I've picked up some TETRA mics and don't have a TRBO mobile to test them on. I'm 99% certain they are identical apart from the part no label and price tag

    The specific models I'm looking at are

    Desk Mic
    TETRA RMN5106A vs TRBO RMN5050A

    Fist mic
    TETRA RMN5107B vs TRBO RMN5052A

    Heavy duty fist mic
    TETRA RMN5111B vs TRBO RMN5053A

    Any answers gratefully received.

    Thanks
    Andy

    I am not sure about the mobile radios, but a lot of the accessories for HP is not cross-compatible. A bit annoying.
    Usually I use the accessories cataloge to check which product that works.

    I did tests and work very well, RMN5107B with TRBO RMN5052A, and RMN5106A with TRBO RMN5050A, are compatible.
    RMN5111B no test.
    All my radios are TRBO Gen 1.
    I'm currently using and no problem.

    Thank you Eduardo, I thought that would be the case, it certainly was with the previous generation TETRA mics that had the RJ plug and worked fine on analogue radios. It's obviously just another case of Motorola using a different part number to justify differential pricing.
