Can I assign my pigeon electronic rings without having to do it through PideXX software on the computer and the need for a Clubsystem?

If you have a Benzing M1, M2 or M3 clock then yes you can assign your own rings using the loft antenna pad. You can not do this with the G2 clock. With the M2 and M3 touch-screen it is very easy to do as it brings up the QWERTY keys on its screen.
