[ICOM] 756PRO3 - popping sound?

[Vladimir Sidorov]

I have to admit, this problem is not completely eliminated in the Pro3. In 
my case it only shows up with stronger sigs, only, and I have managed to 
mask it by some adjustments, but it does exist still. However, I would not 
pay too much attention to that and would never consider it as a purchase-not 
purchase factor, as positive aspects of the rig clearly overweigh this 
issue.
