(5) Memory channels & banks

It is convenient to store commonly used frequencies into a memory channel along with mode etc, this

saves having to key the data in over and over again. Memory read is very straightforward and quick

when compared to re-typing all data.

5-1 Memory channel overview

Think of memory channels as pages in a notebook each of which is numbered to identify it. Data may be

written to each new page (memory channel) and each page may be overwritten with new data, they can

be used over and over again. The AR8200 has 1,000 memory channels in addition to 10 ‘quick

memory’ channels and a priority channel.

Each memory channel may hold:

one frequency

receive mode

tuning step

step-adjust

frequency offset

attenuator setting

noise limiter status

AFC status

pass status

write protect

text comment of up to 12 characters

The alphanumeric comment may be used to ease identification at a later date and to provide text search

facilities.

The 1,000 memory channels are divided into 20 banks, each initially having 50 channels. The memory

banks are identified by letters A, B, C, D, E, F, G, H, I, J (upper case letters) and a, b, c, d, e, f, g, h, i, j

(lower case letters) and initially numbered from 00 to 49.

Examples are “A00” for the first channel location in memory bank “A” and “A49” for the last memory

channel in memory bank “A”. “e15” is the location of memory bank “e” (lower case) channel “15”.

During the manufacture and testing of the receiver, various test frequencies may be entered into the

receiver’s memory banks so the memory locations may not be completely blank.

&Note: Where memory channels and banks are empty the indication “- - -” is often displayed.

The stored data may be quickly and easily recalled, changed or deleted using the memory recall, edit

and delete facilities.

&Note:

It is suggested that one or two frequencies be held in each memory bank

to make the recalling and scrolling of memory banks fluent, if no data is stored, the

AR8200 may take up to 5 or 6 seconds to respond when attempting to change memory

bank while the CPU checks for data.
