Hi AMSATERS
The CAPE team is having trouble copying the bacon's from out sat below is a
table of our receiver noise with different azimuths notice our system
temperature terminated in a 50 resistor is 367 deg k and when connected to
an antenna ranges from 4000 to 12000 deg k. The noise appears to be white
noise
Question
1. Does this seem reasonable?
2. If the noise is not reasonable how to you go about trouble shooting
it?
3. We are concerned about the gain of our antenna to help us trouble
shoot this question what is the bacon at 145.935 mhz received level on
fundcube-1 what is your antenna gain and what range to the sat did you
observe the receive level?
