My problem is that in that case, the maximum speed is only one packet ever half second is emmited. This is due (to me) to the time the radio emettor needs to bring the power up and running for emitting the packet. The problem is that once the packet is sent, the radio stops the emission, that means it has to start up again for the next packet. I didn't find any mode for telling the emetor to stay up even if there's no packet to transmit....... So I'd like to know if someone could help me eather for configuring properly the built-in TNC or to use a soundcard modem in the same purpose ( have numeric transmission with the less delay possible in fact ). Thank a lot (sorry for the not perfect english i am french) Alex Chappaz
