If we can believe Cambium, they have quite a bit more secret sauce
than just the GUI.

I am not sure why the signals would read differently, but i'm curious
how you arrived at the 60 to 70% throughput increase.
Other than the ability to sync, I thought the main difference between
UBNT's M series and ePMP was the user interface??

I just changed two low bandwidth 5 MHz width PTP links from Rocket M2
radios to ePMP 2.4 GHz non-sync radios. The "signal strength" is
about 10 dB lower with the ePMP radios. Do they use a different
mechanism to calculate signal strength?
Link 1:
* 2x Rocket Dish RD-2G24
* Antennas were not re-aimed when switching radios
* Radio outputs are maximized on both systems to FCC PTP limits
* UBNT signal read -62 dBm Tx / -61 dBm Rx
* ePMP singal reads -72 dBm Tx / -70 dBm Rx
Link 2:
* 1x Rocket Dish RD-2G24
* 1x L-Com DPD 18 dBi Dish
* Antennas were not re-aimed when switching radios
* Radio outputs are maximized on both systems to FCC PTP limits
* UBNT signal read -70 dBm Tx / -72 dBm Rx
* ePMP singal reads -80 dBm Tx / -82 dBm Rx
Both links were stable, and both links appear stable now. Both ePMP
links have 60-70% more throughput. Do I just need to adjust my mental
meter 10 db? Are the new signals actually as concerning as they feel?
Thanks - Chris
