By mapping out sites, I mean with DSDPlusTry this...
Go to RR Frequency Database
Select CLMRN Database
Under Name choose your site.
Click on the site your interested in, Under the site name it will show a line and lead you to the next page.
Under the site MAP it lists the frequencies in use.
Additional information click on the site callsign. It will show all frequencies licensed for the site but the frequency list should
show the frequencies in use.
Hope this helps...
