This one does conform and should function like legacy, out of touch,
radios. Since this radio is calibrated to a 50 Ohm load with the
internal generator producing a known voltage, AGC-T is calculated to dBm
or as close to it as we could get.

Read this article. It should clear up a few misconceptions regarding AGC-T.
Remember this is a software defined radio and not everything works like it did
on a traditional analog/dsp radio.

Subject: [Flexradio] Automatic Gain Control Threshold "AGC-T" versus reality
Greetings all,
I am wondering if anyone in "FLEX LAND" can tell me whether or not
there is a known functional relationship between the "AGC-T" setting
and receiver input signal to noise ratio (SNR). I have read several
postings related to adjustment of AGT-T for good, or desirable
performance. My experience with traditional receivers tells me that
this parameter should, in principle, be a "set and forget" parameter.
Pick the number of choice, typically between 0.5 and 2 micro Volts
into 50 Ohms. Not that it matters, but I am using an F5K.
