Comes with original manual and box.

The threshold knob on the front panel is damaged. Threshold functions similar to squelch and may be unnecessary to some users. The TNC still works without threshold.  If threshold is required, Workaround is to use the radio squelch or radio volume. The newer pk88 actually was designed without a threshold knob.

Includes ONE homebrew radio cable that works with Kenwood and the propriertary AEA rear connector port.  Buyers with other radio can splice the AEA cable to connect PTT/output to non-Kenwood rig.  The rig cable mates with the back connector on the TNC

Includes a rare hard to find Oscilloscope cable which connects to the back of the TNC!

Some copper-colored oxidation has occurred at two of the chassis screws and around the battery back and chrome-plated RCA port. There is a pea sized discoloration on the circuit board where the oxidation rubbed off around the battery.  This has no affect on the TNC.  The oxidation probably occurs from metal surface time being exposed out of the box.

Includes 12 volt power supply for USA voltage. The power supply is a generic wall adapter.
