between

(slow scroll-

ing) and

(fast scrolling). Somewhere in the middle of this

range is a good compromise. There will be some radios that

will not be able to keep up with a setting of

ything less than a

message.

AF List

The other RDS housekeeping function alluded to involves the

AF (Alternative Frequency) list. An RDS station with rebroad-

cast translators sends a list of all the frequencies it is using.

The radio then searches for a better signal on one of the given

frequencies and switches to it with almost no audible interrup-

tion. The main transmitter and all associated translators must

retain and transmit this same list for the feature to work

properly.

Highlight the

AF List

item and

push

the knob.

Bracket the list of frequen-

cies on the left and

push

the

knob again. Now

turn

the

knob to scroll up and down through all the FM broadcast allo-

cations. When you get to the frequency of your main signal, or

any translator for that signal,

push

the knob again to enter that

frequency into memory. A checkmark will appear beside the

frequencies chosen, and the total number selected for your list

will appear in the

AFs

window.

To delete any single AF, simply select it and

push

the knob.

You may bracket the

Clear AFs

button and

push

the knob to de-

lete

all

AFs to start over. Don’t fail to enter the frequency of

the main transmitter in addition to all translator frequencies.

Finally!

When all RDS parameters have been set,

then

navigate to

RDS

On/Off & Injection

and turn RDS

RECEPTION TOOLS

The SDR (Software-Defined Radio) front-end of the AARON 650

incorporates various means of improving reception under ad-

verse conditions. A complete technical explanation of these

utilities is not within the scope of this manual, but each will be

addressed as to its basic function and how it may be adjusted

to help cope with reception problems.
We refer to these built-in utilities as Reception Tools and offer

a range of adjustments over parameters that affect their opera-

tion.

NOTE:

Most of these tools are available only when the AARON

650 is operated in the Stereo-Regen mode; exceptions will be

noted.
