Problem !!

The project is come to a hold, the RX- PCB was working very fine for a day, a lot of signals and good modulation.
But suddenly it beginst to smoke, nothing was attached and was on the table with only accu connected !
Big smoke event.. so end of Project and homebrewing !!

Sorry No further foto's and comments will follow here .

 

PROJECT CLOSED!!
