Hoping I can find the right expert that can tell me what I'm doing wrong. I recently purchase the Raspberry Pi 3, installed the Raspbian operating system, installed the APRX software (aprx_2.08.593-1_armhf.deb). Plugged in the TNC-X to a USB port. The raspberry recognizes the TNC-X as usb-Coastal_ChipWorks_TNC-X_by_W2FS_FTWWY120-IF00-prt().I edited the aprx.conf file to (comment lines deleted for space)mycall KC3BHK-1

With the R-Pi, the USB bus can, in certain circumstances, have some pretty heavy voltage fluctuations – it depends on what you are using as a power supply for the Pi, and how many devices are drawing power from the USB bus.
OP, if you have not yet tried, look into getting a powered USB hub for your Pi, and connect your TNC-X to that instead. This should stabilize the power. However, for the Pi, I highly recommend the TNC-Pi instead – I have one running my APRS I-gate/Digi, and it works like a dream!

I don't understand where your theory of voltage problems would come in when using a USB connection.
Have you confirmed that /dev/ttyUSB0 is the correct device for the TNC-X's serial port? What does "dmesg" say when you run it from a terminal after you plug in the TNC-X?
If I recall correctly, the TNC-X is a KISS-only device, so it not being in KISS mode is probably not the issue.

Very true. I ran into this previously with a Pi2
Glad to hear it! Those ID-10-T errors are a pain in the neck aren’t they? At least the magic smoke isn’t all gone!
For starting up – if you get the pre-made deb files for APRX from thelifeofkenneth.com, it includes an init script you can activate with a simple update-rc.d command:
http://thelifeofkenneth.com/aprx/debs/aprx_2.8.2-12-g820690e_raspi.deb
You can install it with a simple dpkg -i command.

Ok. The problem has been isolated and fixed. It wasn't a voltage problem, it wasn't a driver problem, it wasn't a connection problem. It was an I D Ten T error by the operator! Looking at the manual for the TNC-X today, I reread the setup and configuration instructions, and realized, I still had the jumper for the port speed set in the default position (1200) and hadn't actually tried the 1200 setting in the aprx.config file. Changed the port speed to 1200, started it up with -dv, and VIOLA! Works like a charm. Now on to the next step of getting it to start on boot, and get the external antenna on the house.
