   The symptoms are that when tuning the frequency jumps and going upwards it   
   drops back down to a lower frequency and is sometime even had to go up to a   
   high frequency. Often it jumps so much even when tuning up in frequency, the   
   jumps are such that the    
   frequency goes below the original setting. Going down frequency is fine. Very   
   strange indeed!
