Topband: Proposal: Off-Frequency CQ Calling on 160 m

Hi,
 
I would like to make a small suggestion regarding CQ calling practices on 160 meters. Many stations tend to call CQ exactly on whole-number frequencies, such as 1812.0 kHz, 1822.0 kHz, and similar. Unfortunately, these exact integer frequencies are often affected by various industrial noise products and spurious tones, which makes it very difficult to copy weak signals.
 
A simple solution would be to move just a little off these whole-number frequencies—even 100 Hz up or down is usually enough to avoid the interference. This small shift can significantly improve the ability to hear weak stations.
