Re: Smoked my 40

Several questions.  Did you have a reasonably tuned antenna connected?  What version of the firmware were you running?  In earlier firmware revisions if the GPS was connected to the QCX with power connected, the transmitter would be keyed as the gps inputs and the key inputs share a common pin.  The last two revisions of the firmware disable the tx if GPS connected and not in beacon mode.  Most likely you damaged the 3 final transistors and the driver.  This is not uncommon.
