[App_rpt] Problem tuning USB Radio Interface

I finally figured out that the PTT wire somehow had gotten moved and was 
just barely touching pin 14, not sure how this affected the receive 
tuning, but since I fixed that it worked fine. However, since I decided 
to re-solder the wire so that it was in a better position, I broke the 
pin off the chip. So as soon as I order another usb adapter or two, I'll 
be up and running. Thank you for the help.
