Radio Receivers
When a receiver has good blocking performance, this means that

Its detector suffers from burnout
Its image frequency rejection is poor
It is unaffected by AGC derived from nearby transmissions
It does not suffer from double-spotting

The local oscillator of a broadcast receiver is tuned to a frequency higher than the incoming frequency

To permit easier tracking
To allow adequate frequency coverage without switching
To help the image frequency rejection
Because otherwise an intermediate frequency could not be produced

Indicate the false statement. Noting that no carrier is transmitter with J3E, we see that

Production of AGC is a rather complicated process
The receiver cannot use a phase comparator for AFC
The transmission is not compatible with A3E
Adjacent-channel rejection is more difficult
