OK... So I have a client that has an old antenna near their studio that was a former main site back in the day. The thing hasn't been used as a main since the 80s. It seems to sweep ok so it's still useable RF-wise. The site is well within the 1mv and covers the main studio nicely. Do I need to file for a brand new AUX site or is there a shortcut that I can use becuase it was a former main site back in the day? I have a copy of their former license and even a copy of where they prepaired to file for this site as a backup (but can't see that it ever actually got filed). Any input would be great! Thanks!
