1899KHz special prenet test to show transmit power differences 08-18-2023
1550-1555ut WW8II transmits a steady 300 watt CW carrier with id for 5 minutes
1600-1605ut WW8II transmits a steady 600 watt CW carrier with id for 5 minutes
1610-1615ut WW8II transmits a steady 1KW CW carrier with id for 5 minutes
W4DEX receives and records the signal using Spectrum Lab this is a 510 mile SE/NW path
KG0VL receives and records the signal using Spectrum Lab this is a 444mile E/W path
1550ut D layer 3.00db, Solar event B7.78
1555ut D layer 3.00db, Solar event B8.03
1600ut D layer 3.00db, Solar event B7.81
1605ut D layer 3.00db, Solar event B7.50
1610ut D layer 3.00db, Solar event B8.02
1615ut D layer 4.00db, Solar event B9.31
With yesterday's data and today's data it looks as though power plays a role in the received signal but the real data is the signature of the signal received . As we watch the signal peak and dip as the ionosphere churns.
