Re: Help with TNC-Pi9k6 serial0 in YAAC


It's at 19200.  I'm using the HamPi image now, and after disabling SSH serial, I can talk to the TNC-pi9k6 and I believe I'm transmitting something based on looking at the signal with an RTL-SDR.  One thing that is odd, is that there is no change in either the pulse of the ammeter on the radio power supply or how the waterfall looks no matter what I set the transmit power to on the IC-7100.  I set it at both extremes of low and high power and it looks like the same power level.  I switched the jumper from 1200 to 9600 and I get a much flatter line, so it looks like I'm transmitting something, just maybe not enough power?  Does the TNC control transmit power through the radio?  Also, I am not using GPS (arrives tomorrow), so I have manually entered in my coordinates.  Thanks for all the help!  HamPi is awesome!
