I submit sample for FCC certification, radio is 30 dBm power at 2.4 GHz. Lab commanded to output 30 dBm with 100% duty cycle but measure only 27 dBm. See attached pics how they have measured the power, they removed the whip antenna and solder the pigtail cable.

a) I saw big solder point to solder the center wire. Can this effect the RF power?
b) Measure point is away from radio. I think they should measure near the radio module (marked with red color in image by me).
