  2. HI,
    i have an RT43 but i have problem with repeater.
    When i push ptt button i can hear on repeater in other radio my voice but RT dont confirm me connection and busy led is always off and i cant ear.
    Is my work program business radio but in this case i dont unbderstand a problem.

  3. Password must be numbers. I entered a word and the software accepted and wrote it. Now there is no way to reset or change. Poor design and nothing in the manual or software says it has to be numbers.

  4. I changed the password to a word and the software wrote it to my RT43. Now it won’t accept the password because it must be numbers.

  5. Buon giorno, ho un computer con windos 11, non ha le porte, ha solo 2 usb. non so come fare.Grazie
