    What is a good TNC for a packet beginner? i am looking for something that will last, but is affordable. i need something that i can connect to my Yaesu radio with an 8pin packet port.

    ?? which Yaesu radio, HF, VHF/UHF, DC-Daylight ...

    Do you mean the 6-pin mini-DIN -- the standard ISO connection?

    The FTM350AR. and it is an 8pin DIN. i believe it is the only Yaesu radio with this connection

    Your Yaesu FTM-350AR already has an internal 1200 bps TNC (usually used for APRS as mobile),
    and this unit was Yaesu's response to the Kenwood TM-D710.

    Yaesu sells an appropriate adapter cable for your mini-DIN 8-pin connector.

    This needs the Yaesu CT-142 cable (8-pin miniDIN to DE-9, serial)
    Kantronics KPC-3+ is popular and new/used units readily available.

    the built in TNC is not accessible from an outside source (ie a computer). basically all you can do is send aprs packets from the radio itself, and display these packets on a computer. what i would like to do is to be able to send messages through APRS from my laptop to the radio then to RF-land. as well as other forms of packet radio.

    OK, the Kantronics KPC-3+ or any APRS compatible TNC (latest firmware) should work.

    The Yaesu CT-142 data cable has an 8-pin mini-DIN to connect to the Yaesu radio and
    a 9-pin DE-9 (serial) to connecting to the PC.
    The Yaesu CT-140 data cable is like the CT-142, but includes an extra lead for connecting
    to an external TNC (6-pin miniDIN)

    For programming this Yaesu radio these cables must use a USB/serial converter that contains an FTDI USB chip; Prolific USB chips do not work at the non-standard cloning baud rate of 48000 baud used in this Yaesu configuration. -- Yaesu/Vertex Support.

    thanks for the help. hopefully i can find a TNC that can connect to my laptop by usb because it has no serial ports.
