HTX202.4 Here is a mod for the Realistic HTX-202 handheld radios that will open the rx audio bandwith by bypassing the rx audio filter. Here is what to do. 1.Remove batteries,power,antennas,mics,etc 2.Remove belt clip and 5 screws that hold the back on 3.Remove back 4.Looking on the pcb with the bottom toward you,look for 2 resistors and 2 ceramic caps in line with 2 tantalum caps to the left of the MC3371D ic.R42 is the 10k ohm resistor in that row 5.The audio filter module connections are the 6 pins left of the row of resistors and caps.pin 1 is toward the bottom of the radio 6.Carefully cut the trace between R42 and pin 4 of the module 7.Connect jumper wire between the R42 side of the cut trace to pin 1 of the module. 8.Reverse steps 1-3 to reassemble radio You should now have full audio bandwidth and the radio will perform much better on packet.
