Hi Steve,

Use the bird meter, and run the transmitter into a known 50 ohm dummy load ( since it will be a non-reactive, resistive load you can make sure the load is good by measuring it with a good ohmmeter.  Adjust the transmitter power until the Bird says you are at licensed TPO,  adjust the tx meter cal to make the tx read 100%.

Blessings!

Hey Guys:

What do you do to certify your TPO is accurate?   

I know a new transmitter probably has an accurate RF output meter, but over time what is YOUR standard?

We have our Bird meter(s) and elements calibrated every so often, but how do you know you are running your legal TPO?

Thanks!
