Subject: Radio Shack HTX-252 Low audio mod

Hi,

I wanted to pass along the following information that I discovered 
regarding increasing the audio level on the Radio Shack HTX-252 
2M radio.  This is apparently a common problem with this radio and 
I was not able to find any existing mods for fixing it - so I decided 
to try for myself. 

Remove the four screws holding the top chassis cover (which has 
the speaker grill) and remove it.  The speaker is conected by a long 
enough pair of wires that removing it should not be necessary.  If 
removal is necessary it is held in place by four screws which are 
easily removed.

With the front of the radio facing toward you locate the variable 
resistor labled RV2 which is located almost dead center on the 
main circuit board.  

Turning this variable resistor clockwise will increase the deviation 
and raise the audio level of the transmissions.  Be careful not to 
increase the deviation too much.

After making this mod to my radio I have been receiving reports 
that my audio is 100% better, and is at a level on par with everyone 
else.

Good Luck
Rick
