(Addendum)

PRE NET TESTING 11-03-2022 on 1899KHz

Today there were 2 stations transmitting

WW8II 5-7second CW Carrier followed by 1 minute later AB4AM 5-7 second CW carrier followed by a 1 minute no signal transmitted and do the sequence over again. So the first signal on the graph is WW8II the second is AB4AM then a 1 minute no signal..

WW8II 510 mile path to W4DEX, and a 546 mile path to AB4AM
AB4AM a 216 mile path to W4DEX and a 546 mile path to WW8II
all 3 stations were receiving
W4DEX was receiving and recording the signals using Spectrum Lab

WW8II transmit on an inverted V antenna, receive on a vertical 7.5ft diameter loop
AB4AM transmit on an extended ZEP and receive on the same
W4DEX receive on a vertical loop

the solar activity was mainly low and without any real change during the test with a D layer absorption level below 1db

***possible phase or polarization of signal ????
