[NLRS] GPS and RTK

[Dr. Gerald N. Johnson]

I think 150 to 170 MHz or 450 to 470. Probably a QRM source not friendly 
with weak signal reception. Essentially two way FM mode, but the RTK bas 
station transmits continuous corrections comparing its GPS reception to 
its known location. Makes the implement repeat position to better than 
an inch despite the randomness of GPS alone. The RTK gear is standard FM 
gear and frequency depends on the users getting a license for the 
transmitter.

It doesn't have to be on when they aren't in the fields, but its crucial 
for planting, spraying, cultivating, and harvesting.

I think you would prefer it was several miles away on the other side of 
a ridge.
