It seems that you cant transmit to a repeater that utilizes a tone when you have APRS running. Also is ther any quicker way to turn off APRS instead of having to disable the modem. Im sure this question has come up but I recently bought the radio and dont understand whty it wont let you change the tone setting while in APRS. I realize that APRS doesnt us the feature but is there a way to have it set for just that one frequency therfore allowing all other frequencies to be able to access the tone feature. Thnks for any help in advance.
