I would guess that's something a frequency coordinator could look into. On 12/11/2015 2:46 PM, Ken Hohhof wrote: It would appear to be interference into Side 1. MSE=SNR, and –7.70 is terrible, not good enough apparently to link even at QPSK. So who is stepping on your frequency and polarization? Or legally on your frequency but not supposed to be aimed at you. Could possibly be some reflection or ducting thing, but the interfering signal appears to be at about –55, which is more than just some low level interference keeping you from achieving full modulation. The other possibility is a radio problem.

Here is what we are seeing: Side 1: # linktest LOCK RSSI MSE BER TX RX 1> 0 -43.40 dBm -7.70 dB 0.00E+00 QPSK QPSK Side 2: # linktest LOCK RSSI MSE BER TX RX 1> 1 -45.00 dBm -34.30 dB 0.00E+00 QPSK 64QAM Any idea what could be causing this? We saw something similar on Giga 11GHz links as well.
