[ICOM] ICOM 706 MKIIG Birdies

[Randi Dante]

Hello,
 
I own an ICOM IC706MKIIG from almost 5 years and recently on the 6 meter band I keep receiving ( also without antenna) some birdies which keep moving down as the 706 keep warming up. In other word the birdies start at about 50.200 and after about half hour I find it at 50.150. Has any body experienced this kind of problem?
 
Thank you and 73 de
