    My name is Christopher Miller, I have a PCB-88 (internal pk-88) TNC that will not transmit, it keys my radio but will not produce audio. I was hoping that there might be a ham in Tucson that has an osciliscope that I might be able to use to diagnose the problem.

    Looks like you might have to buy a cheapie. New 20MHz single channel Oscilloscopes go for around A$155 in VK,probably a bit less in your money.
    They are made in China,but seem to work OK.
    Another possible alternative is one of the Oscilloscope programs you can download for use with your PC soundcard.
    (It may be wise to make up a buffer amp of some kind to protect your soundcard)
    Sorry I'm so far away,or you could borrow my Oscilloscope:D
