Kerchunk Filter
Kerchunk Filter Enable
Kerchunk Filter Disable
Purpose
To enable or disable the Kerchunk Filter.
Remarks
The Kerchunk Filter discourages users from "Kerchunking" the machine. When
the repeater transmitter is off, a new user with a brief transmission (less than
750 ms) is retransmitted with zero hang time. Since the user doesn't hear a
carrier when he unkeys, he's encouraged to make a longer transmission -long
enough to ID while he's at it.
Example
Our repeater transmitter has a vacuum tube final with relay switching. We don't
want to let the transmitter come up for just a fraction of a second at a time, so we
operate with· the Kerchunk Filter
disabled.
A brief signal at the repeater receiver
input
will
bring up the transmitter for the full hang time.
