Channel Mode
The channel mode is for operating with stored data (frequencies) from memory.
RCU6512 has a storage of 2x 20 channels:
•
Channel CH01...CH20 reserved for storing frequencies in 25 kHz channels
spacing.
•
Channel CH01...CH20 reserved for storing frequencies in 8.33/25 kHz channel
spacing.
•
When the device operates in the 25 kHz mode a selection of stored 8.33 kHz
channels/frequencies is not possible.
•
For selection of 8.33 kHz channels/frequencies, the device must operate in
8.33/25 kHz mixed mode.
•
CH: Used channels are shown with uppercase letters (CH).
•
ch: Free channels are shown with lowercase letters (ch).
The word "frequency" also used in the sense of "channel name", as defined in
EUROCAE, document ED-23C chapter 1.3.2.
In this document the word "memory channel" or "channel" means a memory place
identified by a channel number, where a frequency can be stored for later use.

Toggling from "Direct Tune Mode" to "Channel Mode" does not change
active frequency.
o
The bottom line shows channel number "ch01".
•
If any frequency is already stored (CH):
o
The top line shows the stored frequency to the last selected channel
number.
o
The bottom line shows the related channel number "CH..".
•
With the channel number the stored frequencies can be selected.
