Maybe just a dirty volume control? Try a call or e-mail to Cliff at
Avid in Texas. He is a well reviewed Kenwood repair tech, and is known
to give answers to questions that may keep you from having to send it in.
On his list of radios not repairable, the 440 is only listed as not
repairable for the dots problem on the display, other problems may be
fixable depending on parts.
