lbw 1419.963, 1667.957 MHz birdies


27may13: azswings
28may13: birdie strength  vs za



  Project a2767 reported  narrow band rfi near 1419.963 and 1667.957 MHz. Their setup used a 1.5 Khz resolution channels. The 1419 MHz birdie was stronger than the 1667 MHz birdie.

27may13: azswings:

On 27may13 azimuth swings were done to see if there was any azimuth dependence to the birdies. The setup was:

The dynamic spectra show the rfi as a function of azimuth:
