I was very cautious and finally got the uBITX?wiring correct after looking at all the posts.? It was receiving great until I unplugged my headphones and
plugged in a speaker.? I fried U1!? My speaker plug was not stereo it was mono plug!? So that's why U1 audio amp fried.? So I just ordered 2 TDA2822M's
from Amazon.com.? I am unable to use the uBITX until I replace U1.
I am very upset about this audio circuit design!? This circuit seems to be the Achilles heal of this radio, including a?very loud popping between?receive/
transmit.? I would?like to use a speaker in the future.? I will?be sure to be very careful of the wiring of any?speaker.? I hope to have my first contact soon!
A very unhappy
