Re: Airspy HF+ BDR 110dB

What kind of response time (time constant?) is the AGC running?

I will be using my AirSpy HF+ in the receive loop of a Icom IC-7610, and when I transmit there is likely to be a bit of RF ending up in the AirSpy. (not 100% sure how much yet, will be a function of the TX/RX relay isolation.
Would be good if it didn't take a long time to recover...

How will then the trained professionals explain this:

BDR= P1dB - Noise floor

P1dB=IP3-10db
P1dB=15-10 = +5dBm

BDR=+5- (-140)
BDR= 145dB

This is a big difference, 110db or 113dB over to 145dB ?
