0:00 - This video covers PowerSDR ke9ns v2.8.0 ESC "Diversity Reception" (best to watch in 1080HD)
0:24 - Noise We want to eliminate (Frying Bacon noise)
0:35 - Antennas TA-33 JR as my main antenna, G5RV as my RX2 antenna

0:43 - Activate RX2 (2nd receiver)
0:47 - ESC "Sync" button (syncs up both receivers to the same DDS)

0:50 - ESC "Enable" button
0:55 - Turn off RX2 (just dont move frequency at this point)
1:12 - Adjust the ECS Phase and magnitude of RX2 compared to RX2
1:17 - Phase and Mag adjusted to eliminate the noise (same noise found on both antennas). The Phase of RX2 signal was inverted to cancel out common mode noise between RX1 and 2.

If you move frequency you will need to turn RX2 back ON, and readjust the ESC
