This is a continuation of posts that I made under the Marine Section. I thought I was getting a little off topic so I decided to put it here...Lately I have been hearing ALOT of comms on 156.225 with PL's of 225.7 and 229.1 in Chesterfield County. Upon further investigation I found out that this frequency and 154.755 are both transmitted from an antenna located at the Defense Supply Center. What does Chesterfield County use these frequencies for???
