Did u turn the power up on the epmp ptp links or is it @ default.

Other than the ability to sync, I thought the main difference between UBNT's M series and ePMP was the user interface??

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
