Subject: cec-follower: create analog channel frequencies Author: Jiunn Chang <c0d1n61...@gmail.com> Date: Thu Sep 19 12:47:01 2019 -0500 This frequency table will allow proper testing of tuner control. There are three frequencies per analog broadcast type and broadcast system, so tuner increment and decrement can be tested.
