Subject: Possible dead voice guide chip in Kenwood rig.


Hello listers, I am writing regarding my recent intermittent 
TMV-71A speech chip problems, it went out again yesterday.  I 
took off the top and tapped and wiggled the voice guide chip 
whereupon it started talking again.  However, today, it is dead 
again.  This time I turned off the rig and unplugged the chip and 
replaced it again.  That didn't fix it.  guess the only way to 
check it out is to take it to my local HRO after finding out they 
have a voice chip in stock and trying a new one to see if that 
remedies the problem or if it's in the rig itself.  Has anyone 
else had issues with the voice guide chip going out or being 
intermittent? Jim WA6EKS
