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
