Add a ROGER BEEP to the GALAXY DX-33
The GALAXY DX-33 has the capabilities of a factory roger beep that was not added at the factory , You can finish putting in the roger beep if you are a CB hobbyist that likes to experiment . First with a soldering iron and some solder wick clean out the holes on the board where R179 , R180 , R181 , R182 , R183 , C134 ,C136 , C137 ,C138 , D83 and TR33 should have been placed at the factory . Then at the local electronics store pick up these parts . (resistors) 1 MEG , 2.2 K , 220 K , (two) 4.7 K . (capacitors) 01 uF , (two) .0047 uF , 2.2 uF . (diode) 1N914 . (transistor) 2SC945 .
After cleaning out the holes add the resistors first as in step 1.
1.) 1 MEG into R179
2.) 220 K into R181
3.) 2.2 K into R180
4.) 4.7 K into R182 and R183
Then add the capacitors as in step 2.
1.) .01 uF into C136
2.) .0047 uF into C137
3.) .0047 uF into C138
4.) .2.2 uF into C134
Then add the diode (1N914) into D83 . Add the transistor (2SC945) into TR33 . observe the proper way to install these last two components , they are marked on the board . Last solder a wire into the hole marked J9 and the other end to a switch . Then solder a wire on the other side of the switch to a +5 volt supply . That's it...... |
