distance, depending on how loud your voice is. An automatic regulator ensures that your partner
always hears your signal at the same volume.
It is best to test the best distance from the microphone for yourself with the help of another station.
•
To make the operation as easy as possible, we have not applied any double or second
functions to any push button. So every push button is only for the function which is printed
on the knob or just besides the knob.
•
The activated function will then be shown in the display.
PRI Priority channel: short press: switch to the priority channel respectively back again
to the manual channel selection
TON Tone button to enable a high-cut audio filter for better noise suppression
TSQ Tone squelch (pilot tone or CTCSS) is a new function in CB radio communication.
This tone squelch replaces the conventional noise blocker, which reacts on a
weaker noise or an increasing field force. Instead there is an inaudible, very well
defined low frequency tone between 67 and 250 Hz in every transmission.
This tone will be decoded by the partner station if this station also is equipped with this
function. The loudspeaker will only turn on, if the device "hears" this tone. So the reception
can be used to select between several stations or groups, who all use the same
pilot tone.
So you can build an own group with your friends for example und everybody in this group
can listen to the other ones, but there will not be any external signals.
With activated TSQ the normal squelch is not necessary (and not activated). So the
standard squelch setting is disregarded in CTCSS mode. The radio has the ability to
decode the CTCSS codes always in the best sensitivity and does not react to any noises
or external signal without CTCSS.
•
Theoretically there are 48 user groups on each channel possible.
•
The first 38 tones are internationally standardised, the codes from 39 to 48 are
additionally possible with other AE 6890 at the distant partner stations only.
CTCSS codes are often also described as Sub Channels or Pilot Tone system.
This function is also ideal for CB gateways!
TSQ on/off: press TSQ
Changing CTCSS code: press TSQ long until the code display is flashing. After
that, select with the channel knob a code between 01 and 48 and confirm with TSQ.
M1- M3 Select memory channel: for recalling a previously stored memory channel, just press M1,
M2 or M3 shortly.
To change a memory channel choose a channel, press M1, M2 or M3 at least for about 3
seconds. This will overwrite any previous channel setting. This feature is perfect to save
often used channels.
