cb az swings, 5ghz rfi  28jun16

29jun16



         Angel and Israel made field trips to yiyi avila's tower on 27 and 28jun16. They found :

On 28jun16 i did 2 azimuth swings to see what was left in cband rfi around the uni band.
On 30jun16 angel and i made  field trip to radio redentor/HQ tower in utuado. (more info).


The setup was:

Birdie power vs azimuth.

I also plotted the rfi power vs az position for the non-overlapping portion of each rfi (.ps) (.pdf)
The table shows the rfi bands that were found:
Frequencies with common colors, have similar  azimuth dependence
