What memory channels are

A memory channel (or channel) is a frequency saved with all its settings: mode, sub-tone, power, name. Memory channels live in banks: each bank is a notebook of 500 memory channels, and there are 16 banks.

The easiest way to fill them is the PC program. From the radio you can still save, give a name and delete.

Using the memory channels

Hold down 3: you go from frequencies to memory channels. The number appears at the top left, for example M0008.
Change memory channel with UP and DOWN.
Or type the number: 8 and then MENU goes to memory channel 8. With three digits it confirms by itself.
Hold down 3 again to go back to frequencies.

Save, rename, delete

I want to	I do
Save the frequency I am listening to	In frequency mode: F and then 4. It goes into the first free memory channel and you read Add Mem CH-.... If there is no more room: Memory Full.
Give a name	MEM menu, item ChName: choose the memory channel, MENU, type, MENU.
Delete a memory channel	On the memory channel: F and then EXIT long. Or from ChName with the * key (DEL? =YES: press again).
Put the memory channel in a group	On the memory channel: F and then 9.
See only some groups	On the memory channels: 1 long, or MEM menu, item ChGroup.
Make the scan skip a memory channel	On the memory channel: F and then 4.
Bring the memory channel to the VFO so I can move	F and then 3 long.
Change bank	On the memory channels: F and then 1. Or MEM menu, item M Bank.
Go to the favourite channel	F and then 9 long (you choose it with 1 Call).

What to see on the memory channelsWith ChDisp (MEM menu) you choose whether to see the frequency, the number, the name, or name and frequency together.

The presets

A preset is a ready-made band. In one move it puts the VFO on the band you want, with all the right settings, and tells the scan where to start and where to end. The radio holds 24 of them, and twelve are already made. To use them you need the Preset module: it loads by itself and does not appear in the list of modules.

A preset carries the name, the two band limits and the settings.

What is inside a preset	What happens when you recall it
The name	It appears above the frequency.
The lower limit and the upper limit	The VFO goes to the lower limit. The scan will stay between the two limits.
The step	The arrows jump by that step.
The mode, the bandwidth, the gain, the squelch	They are applied to the VFO.
The power	It is applied to the VFO.
The sub-tones	They are not touched: the ones you had stay.

Recalling a preset

Open the list in one of these ways: F and then side key 1; or side key 2 held down (if you have not changed the side keys); or MENU, 2, item Preset.
Choose with UP and DOWN. Empty places show as ---: on an empty place MENU does nothing.
Press MENU. The VFO you are using goes to that band and the preset name appears above the frequency.
EXIT instead closes the list without changing anything.

The name disappears when	Why
you leave the band of the preset, with the arrows or by writing another frequency	You are no longer in that band. If you come back in, the name appears again.
you hold down EXIT	You reset the VFO: it is no longer that band.
you mark another scan limit (F and then an arrow)	You decided where to search: they are no longer the preset limits.
you recall another preset	The name of the new one appears.
you are outside the band and you start the scan	The scan starts from the frequency where you are and the preset is forgotten: the name does not appear again, not even if you go back into the band.

The name stays while you tune aroundAs long as you stay inside the band the name stays, even if you move with the arrows or write another frequency of the band: it reminds you in which band you are searching.

The presets and the scan

After recalling a preset, hold down *: the scan runs only inside that band, from the lower limit to the upper limit, and then starts again. The frequencies you put in the blacklist with a short * are skipped.

If instead you write a frequency outside the band of the preset and start the scan, the scan starts from there, on the band of that frequency, and the preset is forgotten. The limits you set yourself with F and the arrows stay even outside the band.

Every preset has its own scan blacklist: when you recall the preset, the radio loads it and the scan skips those frequencies. To save the blacklist you have now onto the preset, open the SCList list and press F and then * (see below); saving the preset from the radio saves it too. The FastScan blacklist instead is emptied: with the new preset it starts from scratch.

The FastScan module also uses the same limits: if you open it after recalling a preset, it looks at that band.

Preparing the presets

The radio already starts with twelve presets made: the 27, 43 and 70 MHz bands, the aircraft band (AIR BAND), VHF 145, UHF 430, LPD BAND, PMR BAND, SERVICES, SAT BAND, SEA BAND and a free one (USER). They are there from the first switch-on, and RESET ALL puts them back as from the factory.

To change them or make new ones there are two ways: from the radio, putting the VFO you are using onto a preset, or with the PC program, which writes them all together.

Saving a preset from the radio

Set the VFO the way you want the preset: frequency, mode, step, width, gain, squelch and power.
If you want to decide the two band limits yourself, mark them as for the scan: F and then DOWN on the lowest frequency, F and then UP on the highest. If you do not mark them, the band goes from 1 MHz below to 1 MHz above the frequency.
Open the preset list (F and then side key 1).
Choose with UP and DOWN the place where to save it: one already full or an empty one (---).
Press F and then MENU. The radio writes Preset Saved.

Preset saved on an empty place: it took the name PR 02.

What happens	Why
The preset takes the limits, the step, the mode and the other settings of the VFO	It is what you prepared.
The name stays the one it had	If the place was empty, the preset is called PR plus its number (for example PR 02). You change the name with the PC program.
The scan blacklist you have now goes onto it too	Every preset has its own blacklist.
The preset name appears above the frequency	The VFO is now on that preset, as if you had recalled it.

M recalls, F and then M savesIn the preset list MENU alone recalls the preset; F and then MENU writes the VFO over it. Careful: what was on that place before is lost.

Preparing the presets with the PC program

In RadioManager, in the radio settings, there is the Preset page: a table with 24 rows.

Column	What you write there
Name	The name you will see on the radio.
Low Range, Up Range	The two band limits, in MHz.
Step	The step.
TX Power	The power.
BW	The bandwidth.
AGC	Who sets the gain.
Mode	The mode (FM, AM...).
Squelch	The squelch.
BL	The scan blacklist of that preset: when you recall the preset, the scan skips those frequencies. You can also fill it from the radio (F and then * in the SCList list).

The EDIT button opens the sheet of a preset. You can save all your presets as a profile and load them again whenever you want, without writing them again.

The list of bands

F and then 1 (in frequency mode) opens the list of the amateur radio bands. While you scroll, the radio already goes to that band so you can hear if someone is there. MENU confirms, EXIT puts everything back as it was. Each band also remembers reverse, scrambler, compander and RF gain. This too is in the Preset module.

The scan

The scan makes the radio run from one frequency to the next and stops it when it finds someone talking. Sc appears at the top.

Hold down *. In frequency mode it goes through the frequencies; on the memory channels it goes through the memory channels; on the FM radio it goes round the whole band, puts the stations in the SCList list and at the end opens it for you.
When it finds a signal it stops to listen, then starts again.
UP and DOWN change the direction.
* short while it is running: "I am not interested in this one". The frequency goes into the blacklist and the scan skips it (Blacklist #1).
Any other key stops the scan where it is. The PTT too: it stops and transmits.

While the scan is running	What it does
2 long	Changes VFO without stopping the scan.
Side key 1 long	Monitor.
8 long	Stops and opens the scan times (Sc REV).
F and then 4, in frequency mode	Saves the frequency in a memory channel and stops.
F and then 4, on the memory channels	Marks the memory channel to be skipped (Skip Set).

With DW or TW you can keep the FM radio on one VFO and scan on another. Put the FM radio (WFM) on a VFO, switch to another VFO with a long 2 and hold *: the scan runs and the FM radio keeps playing. When the scan finds a signal, the FM radio goes quiet and you hear the signal; when it ends, both start again. The FM radio also stays quiet during the scan wait time (Sc REV). If the VFO on the FM radio is the one you are using, a long * searches for FM stations as usual. This does not work for HF VFOs that use the Si4732.

Telling the scan where to search

Go to the lowest frequency and press F and then DOWN. Go to the highest and press F and then UP. Now the scan stays in between. If you recalled a preset, the limits are already those of the preset.

The SCList

It is a notepad where the interesting frequencies end up: the ones the scan found and the ones you add with * short. It holds 40. It is emptied when you switch the radio off.

In the list	What it does
UP DOWN	Scrolls, and the radio goes to that frequency at once.
MENU	Keeps that frequency on the VFO and closes.
*	Removes the line, and also removes that frequency from the blacklist. Frequencies in the blacklist have a * in front.
F and then *	Saves the scan blacklist onto the preset you recalled last: the radio shows Preset Saved. If you have not recalled any preset it shows No Preset. It works even with an empty list.
4	Saves the whole list in the free memory channels.
F and then EXIT	Empties the list (SCList Clear).
EXIT	Closes.

The list opens by itself when you stop a scan that found something. It also opens with F and then side key 1 long, or from the DSP menu, item SCList. F and then * long scans only the frequencies in the list.
