[TenTec] fuzzy sidetone, tuning freeze

[K4IA at aol.com]

Well, the credit card bill arrived and the thirty days is almost up.  Time to 
decide: should it stay or should it go?  I am getting over some of my earlier 
gripes but I have two more issues:

1. Fuzzy sidetone in the headphones.  It comes and goes.  It can be fixed by 
turning the radio off/on but sometimes it takes several tries before the 
fuzziness goes away.

2.  Tuning lock.  If the radio is left alone for a few hours, when I return, 
sometimes the tuning locks.  Spinning the knob makes the numbers on the 
display change but the VFO is not tuning.  Turning off/on solves this one.

Anyone have any ideas?
