When I had our frequency coordinator do an FAA application for us (licensed 
link on tower near airport) and mentioned the discussion here about 2C surveys, 
they acted like I was crazy.  Are you sure this is required?

 

Steve, is this hypothetical, or is the FCC paying you a visit?

 

I know one time I discovered the commercial tower we were on had the lat/lon 
wrong on the ASR.  For us to fix out license, they had to also fix the ASR.  It 
was just a matter of filing a modification.  I also seem to remember something 
about it wasn’t significant unless it was off by at least 1 second or something.

 

Honestly I just use the numbers from my Garmin 64st, same as for CPI data for 
CBRS.  Given several minutes it will usually state accuracy within <10 feet.  I 
check it against Google Earth and they usually match to better than that.  Even 
the elevation AMSL usually matches.  If there was a need for a survey I would 
think it would have to be for AMSL, there’s just no rational reason to need a 
surveyor to certify the lat/lon these days.

Typically if you are filing for FAA or FCC you have to supply coordinates from 
a 2C survey mimium. They assume a certified survey is good enough.

Have any of you guys ever had the FCC verify your transmitter data?

What equipment do they use to verify elevation and coordinate?
