After all this time having the $15.00 Radio Shack Pro-136 in the box for years, decided to open it this weekend and Immediately wanted to open it and see if I can find the DISC output.
When I spotted the NJM2552, i knew right away pin #11 was the one unfiltered audio output since this model is made by Uniden it has the board as the UBC360CLT.
Just a bit challenging soldering the 10k resistor to pin 11 of the receiver IC since its so tiny. With a fine tip and a magnifying glass I was able to do it.
The 2.2nF capacitor was no problem as it goes on the other side of the resistor and grounded.
pictures below are from the link above.
Works excellent with LAPD and searching DMR NXDN DSTAR.
Have fun guys if you decide to do this on your $15.00 Pro-136
