Auto-store
When shipped from the factory, memory bank “J” is reserved for auto-store of memory channels
from search mode. This is a useful facility to quickly build a list of active frequencies. Please refer
to section 8-7-5 of this manual for further information regarding AUTO-STORE.
Dynamic memory bank resizing
The lettered memory banks are regarded as a ‘pair’ making a total of 100 memory channels per bank,
initially equally divided between the upper and lower case letters. It is however possible to reallocate
the 100 channels in blocks of 10 channels between the same letters A/a, B/b, C,c etc This means that
the initial 50/50 may be reallocated as 60/40, 70/30, 80/20, 90/10, or 10/90, 20/80, 30/70, 40/60. This
‘dynamic’ memory reallocation can be useful to optimise the memory layout where a large or small
collection of frequencies need to be monitored without unnecessarily wasting memory banks with just a
few channels occupied.
Write protect
It is possible to write protect individual memory channels to prevent accidental deletion, whole memory
banks and a ‘global’ write protect facility are also available.
Memory backup
The data contents of memory and search banks are held in an flash-ROM so that no backup battery or
capacitor is required for memory retention.
Note: When the AR8600 is switched OFF, all VFO data will be automatically stored.
Should the NiCads (or dry batteries if in use) become completely exhausted, the last stored
memory channel or last VFO data ‘may’ be lost if the AR8600 is not powered-down using the
key and insufficient power is available to save the data.
5-2 Storing VFO frequencies & data into memory
It is possible to save frequencies to the ten quick memories for simple recalling but for longer-term
storage, the 1,000 main memory channels offer a better and more flexible system.
The process to save a displayed VFO frequency to memory is as follows:
a) In VFO mode, select the required frequency, mode, attenuator etc
b) to initiate memory write
c) Use the keypad, main dial or ÕÖ×Ø keys to select the desired memory location
(BANK and CHANNEL)
d) Add a text comment (optional) or delete an existing comment
e) Add memory channel write protect (optional)
f) Exit the menu to save the data to the specified memory location
Lets assume that you wish to store the frequency of 123.500 MHz
(with the attenuator off, noise limiter off, AFC off) into memory bank
“E” location “25” (E25) while in VFO mode with the text comment of
“AIRBAND”. If a mistake is made during programming,
the key to abort entry and return to 2VFO mode.
a) Start by selecting VFO mode then key in the frequency of
123.500 MHz, “mode and step size” are set to the default auto
“AUT” - if not use the key sequence
