Not quite. The FCC requires you to make sure the frequency is not in use before TXing, the idea being you don't interfere with communications in progress on said frequency. Packet, by design, automatically monitors the frequency so as to minimize "collisions". If on occasion you accidentally stomp on a packet, no biggie: it automatically retries a few seconds later. So occasional CTCSS-protected voice transmissions on 144.39 wouldn't really be a problem, although an extended rag-chew would be. Bob NO6B
