Never a dumb question. Who's next
For a 250 kHz wide pass band divided into 3 kHz segments ( expected
Rx load ) , what level AGC should be expected in the Telemetry if 70
% of the 3 kHz pass bands are active?
Is that the AGC level selected to protect the ( AO-40 ) down link
anplifier ?
How much power would it take on Rx input for one up linl signel to cause
the same level of AGC indication?
Is there a dB output reduction related to up link power input as the
AGC approaches the protection level?
Is there more than one AGC detection level that causes a response
to the down link amplifier?
Is the protection AGC currently set to an expected input load
rather than a full load ?
Is it proper to believe that any signal found to be above the middle
beacon level,
has to be a mode L up link.
Just wondering.
