110% agreed there. > This is a huge advantage of P25 - those repeaters CAN be dual mode. > D-STAR is digital only. But it's still the user radio that implements busy-lockout in P25. In our local mixed-mode system, analog users (who can't be bothered to put in a CTCSS tone on receive) regularly pop up in-between digital transmissions musing, "What's that horrible noise getting into the repeater?!" And if the digital users have analog/digital busy-channel lockout turned on in their rigs, they see the receive light is on, and they can't PTT until the confused ham has given up. LOL! I usually monitor quietly with another analog rig when we're playing with P25 so I can cross-over and explain that what they're hearing isn't "interference". -- Nate Duehr, WY0X [EMAIL PROTECTED]
