I am looking for something that will last, but is affordable.
I need something that I can connect to my Yaesu radio with an 8-pin packet port.
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.
Hal Mueller's explanation of FTM-350AR Packet usage (using TNC built into radio)
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.
Purchase a Quality USB to RS-232 adapter cable. I recommend FTDI cables. WHY?
Thanks for the help. Hopefully I can find a TNC that can connect to my laptop by Universal Serial Bus (USB), because it has no (RS-232, DE-9) serial ports.
Primary drivers are usually loaded by MS Windows automatically.
These FTDI USB cables are available from Mouser, in various lengths.
