Sorry - you're right - I just checked my notes again, and one of my two ax5043's did go down to -115 with a dummy load.  The other only went down to -90 or so.

Hmm.  Odd.  With no signal being sent at all, I'm at -114 or so.  Do you get that kind of value with no signal in the air?

Good to know it is pretty good though.  And on the other end, we are unlikely to get a signal as strong as -27!

Thanks for checking!

Using the new "get rssi" command, I checked the calibration of the RSSI when driven with my HP signal generator tuned to the input frequency.

The reported values closely (within 2-3 dBm) matched the generated power between -90 dBm and -30 dBm.  -27 dBm was the largest RSSI value reported by the ax5043 even with increasing input power.

One of the two ax5043s was able to go down to -97 dBm, the other one only went down to -90 dBm (more or less).
