Legal and General Information
The legal regulations in some countries demand a printout of our CE Declaration of Conformity in its original
wording (editorial status: March 2010). The latest regulations, announcements and other documentation for this
device are published in the service download area at www.hobbyradio.de or www.alan-albrecht.info. Please
observe the country-specific regulations when using this device and take the obligatory registration in individual
countries and possible operation restrictions serious!
As Amateur Radio, there are important restrictions for use of this radio. Most important is the following
The radio is allowed to be used only by licensed radio amateurs
• It is not allowed to transmit on frequencies outside the allocated 10 m amateur band, even if the frequency
switching of the radio should allow it technically.
• The band limitation depends on country specific amateur radio regulations. For use in Germany, there is
no band limitation requested for amateur radios.
• In other countries except Germany it may be allowed only to use band limited equipment.
• Even if you have an Amateur radio license, the license does not give you the right to use this transceiver
for any other purpose than amateur radio in the 10 m Band.
• Persons, who do not have a valid amateur radio license, are not allowed to operate this radio.
• The radio fulfills the technical requirements of European Amateur radio standard EN 301 783-2.
Among other parameters, this means, that the essential requirements for radiations in the spurious domain
are within limits. However, any combination with power amplifiers, permanently connected SWR meters or
automatic RF operated antenna switches may increase the radiated spurious values. The radio amateur is
responsible to keep his radiations within the amateur radio limits at any time. It cannot be excluded, that
the national authorities may impose restrictions of use in individual cases.
• Please consider the minimum distances between antennas and persons in the near field of your antenna
installation (as base station) and observe the national requirements for site registration, where requested.

Preparation for Use
General Use Instructions
This AM-FM-SSB transceiver AE 485 S is a universal 10 m radio for 12VDC power supply. It an be connected to
powerful 12V batteries, such as rechargeable lead batteries, but also via a suitable 12V power adapter with at least
6A stabilized constant current to 230V mains power supply. Due to its SSB operation, demanding repeated fine-
tuning and delicate operation, the radio is not intended for the use in vehicles when driving.
The radio is intended for intermittent operation with an average transmission time of approx. 10% of its duty cycle,
as it is typical for voice operation. This device is not intended for continuous transmission without regular reception
periods as cooling phases. Avoid subjecting your radio to high humidity, extremely high or low temperatures, dust
and direct sunlight. Only open the casing of your radio if you are knowledgeable in this regard, have the correct
tools and measuring devices.
The device comes with the international 10 m band range 28.000 MHz to 29.6 MHz with user selectable frequency
steps or channel steps similar to the common CB rules. AM, FM, USB and LSB can be selected.
Any extension of the frequency range und the use of other channels and modes than permitted in the individual
countries may lead to prosecution.
Connect to Power Supply
Connect your device with the supplied DC cable to a 12V network or a 12V power adapter. Voltage fluctuation
between 11V and 14V for power adapters and max. 15.6V, as in vehicles, campers or boats with rechargeable lead
battery, chargers or alternators, are permissible. Battery and/or power adapter must supply at least 6-8 Ampere
with good stabilization. Do not extend the power cord. In vehicles always try to connect directly to the battery
terminals. In this case you have best immunity against interferences from ignition and alternator and the most
stable supply voltage.
In case the fuse integrated in the DC cable blows, please check the possible cause first (commonly voltage
reversal and a flyback diode has reacted) and replace the fuse only with same type (10 Ampere, American glass
fuse), and never bypass with foil or similar measures!
Connect the red cable to the + terminal, and the black cable to the – terminal of the power source.
The minus terminal for this radio is on the casing, as usual for all modern vehicles. When installing in boats safety
measures against electrolytic and/or galvanic corrosion, such as insulated installation and galvanic insulation of the
antenna connections may be necessary due to the grounding of the casing.
Safety Precautions and Vehicle Installation
The device contains no components that must be accessible for the user during operation. Leave the opening of
the casing to experts. Do not open the casing before disconnecting from 12V power supply. For use in cars, trucks,
boats or RV vehicles mount your radio with the supplied screws and bracket in a suitable position. Ensure that no
risk of injuries for driver and passengers comes from the mounting position and avoid close proximity of air vents.
Do not use your radio when driving. The device is neither intended not approved for this kind of operation.
According to the Federal Motor Transport Authority the device is due to its risk potential only to be used in parked
vehicles.
Select Antenna - Vehicle Antenna
This radio is not to be used with common 10 m base or mobile, or even retuned CB radio antennas, such as a
magnetic foot antenna, balcony antennas, ground plane base station antenna or bult-in high efficiency car
antennas. For electromagnetic compatibility in combination with near electronic components a powerful vehicle
antenna with antenna base earthed via the chassis is to be used. When selecting the antenna position keep the
greatest possible distance to passengers and all vehicle electronics. Avoid the side of the mudguard as mounting
position which is nearer to passers-by on walkways. (this may be the left side in UK and the right side in continental
Europe). Ensure best grounding for antenna base, as this ensures that no HF reaches the interior of the vehicle via
sheath waves.
According to the latest EU directives vehicle manufacturers have the right to stipulate antenna positions and
maximum compatible transmission power for their vehicles. Please observe these guidelines, as you may
otherwise risk loosing the operating license for your vehicle. Ask your vehicle manufacturer for further information.

6
Have your vehicle manufacturer verify that he has no objections against the Amateur radio operation in connection
with the vehicle electronics!
Even though the effects of “electric smog” are controversial, you may not want to expose other persons, who may
think your hobby dangerous, to electromagnetic fields. In case you wear a pacemaker, please observe the greatest
possible distance to the antenna. If in doubt, obtain the manufacturer’s information with regard to recommended
safety distance.
It goes without saying that your antenna is to be optimized in standing wave ratio. The AE 485 S output stage
copes during operation with SWR of up to 1:2 at full capacity and short-term up to 1:3 (e.g. during adjustment).
Never press the transmission button without connected antenna!
The radio is equipped with a SO 239 socket (for PL connector) for antenna connection. For connection and cable
up to approx. 15 m RG-58/U cable is sufficient, otherwise we recommend RG-213/U or RG-8/U cable. Do not use
coax cable for satellite or TV, as these have 75 ohm and are not suitable for radio operation.
Operation as Base Station
Only use an external antenna for AE 485 S. Any kind of interior antenna creates such high HF fields in close
proximity that own electronic devices or devices of others are interfered with, even with sufficient EMC immunity
according to EU directive! For instance hum trouble from your own power adapter or via the microphone to the
transmitter, irradiation into VCR or hi-fi equipment and the like are well known. Especially in SSB mode, rather than
in FM mode, it can come to interferences with other devices due to the pulsating transmission signals.
Location of Controls AE 485 S (The picture is for the similar AE 5800 CB radio version)
Controls and Switches
On/Off, Volume and Squelch Setting
Turn the combined volume/on/off control knob (1) to turn the device on and off. With first use set the volume to a
medium level and turn the squelch button (14) fully counter-clockwise, until you can hear the background noise.
Now set squelch in such way that the background noise just disappears. In this position squelch opens even with
weak signals and is in its most sensitive position.
If setting squelch above this point clockwise, the signals have to be stronger to be put through.
Mic Gain (3)
This control knob is designed for dual function with the RF gain control. Use the upper control knob (3) to set the
sensitivity of the microphone. For the supplied hand microphone the control knob may be set to 2/3 or full
(clockwise). For other microphones the control knob serves individual setting. Optimum modulation is best set with
a control receiver or with an outstation.

7
RF Gain (4)
Use the RF Gain knob (lower, outer dial of the dual control knob) to set the amplification in the RF receiver. Turn
fully clockwise for the unit to have the highest amplification and sensitivity. This setting is optimal for most receiving
ratios. Turn the RF gain control knob back to mask unwanted long distance or interference signals, especially
when deliberately listening to near stations. In SSB mode with high field strength it may be necessary to adjust the
amplification with the RF gain control knob for optimum quality.
Clarifier (11)
This control knob serves the receiver fine-tuning and is only used in SSB mode if the distant partner station is not
quite on the same transmission frequency. In radio circles with several participants you frequently have to fine tune
individual stations with the clarifier for best comprehensibility.
LCD, S Meter and Power Meter
Your radio comes with a large backlit LCD for all settings, such as channel, frequency, status display and analog
values, such as received field strength (S meter) and transmission power. In this way you always have the most
important parameters in view. The S meter setting corresponds with the international short wave amateur standard:
100 µV EMC antenna voltage corresponds to S 9. The S meter uses a 5-stage bar display on the LCD. The
stronger you receive an outstation, the stronger is the deflection on the S meter.
For checking the S meter also works for transmissions as a power meter and gives you an approximate clue about
the output power. You will see that for FM you will always have the same transmission display, for AM the
deflection is generally less, and for SSB it varies with the rhythm of the speech.
Channel or Frequency Display
With first use the unit starts in FM mode and a frequency in the 29.300 MHz range is displayed. The unit starts in
frequency mode. (the pictures below show the similar operating CB radio AE 5800)
Channel mode Frequency mode
The switching between the frequency mode and the channel mode works only when the 454 CH mode is activated.
This is possible for units sold in Germany (but not possible in all countries of sales!):
• To activate the 454 channel mode press first FUNC (12). In the display FUNC will appear.
• Now hold key „2“ (7) several seconds pressed. Now the radio switches to the 454 CH mode (where
allowed).
• In this mode the bands A, B, C, D etc. appear. These are band segments with 40 channels each. You can
change the band segments by successive pressing on key 2 .
(please see the frequency-channel list at the end of the manual. Please note that the channel mode exceeds the
10 m band frequency limits. Radio amateurs are only allowed to use the frequency allocation of their license class.
This is the reason why we are not allowed to ship this radio with activated channel mode into some countries.
• You can toggle your display to channel mode similar to CB radio devices.
• First briefly press the FUNC button (12). The display shows FUNC.
• Now press the 2button (7).
• In the channel mode, the unit switches in steps of 10 kHz and in a channel numbering like on CB radio
standard of international 10 kHz resolution, with some channels showing a 20 kHz step instead of 10 kHz
(for historical reasons).

8
• You can tune the frequency via the CHANNEL knob (9) on the unit or with the UP/Down buttons on the
microphone.
• Press FUNC followed by 2 to toggle between the display modes.
Frequency Steps (channel knob)
Per default the frequency steps are 10 kHz. You can change the step width by key STEP (5) to 1, 10 or 100 kHz
steps. After 1 x pressing STEP you will see the cursor appearing below the corresponding digit of the frequency
readout, depending how often you press the button. Now you can select the digit of Your choice with the channel
knob or up/down. Pressing FUNC (12) will switch back to 10 kHz default step system. The 10 kHz steps now will
start from the before shifted frequency!
Example: You have used STEP and the channel switch and reached 29.138 MHz. Now you press FUNC and use
the channel switch again. Your next frequency will be 29.148 MHz, 27.158 MHz and so on.
Buttons AE 485 S (5-12)
The buttons of your unit are multi-functional and change automatically – according to the mode – or in combination
with the FUNC button (12) manually. To avoid confusion you will find only the name of the corresponding function
in this user manual. For instance for pressing the MODE button you will find “MODE” and not the all names of all
functions for this button, such as “MODE/LOW/5”. Furthermore, all button functions, which are only possible in
connection with the FUNC button, are printed in blue.
Select Mode
Press the MODE button (8) to toggle between AM, FM, USB and LSB. The selected mode is displayed. The
abbreviations stand for:
AM Amplitude modulation A3 with full carrier
FM Narrow band frequency modulation (max. 2.0 kHz range)
USB Single-sideband modulation, upper side band
LSB Single-sideband modulation, lower side band
The different modes for Amateur radios are partly historical, as Amateur radio started with AM more than 50 years
ago. AM (amplitude modulation) mode corresponds with the technical operation of medium wave and short wave
broadcast und is, except for CB radio, currently used for aircraft radio. While speaking the transmission power is
adjusted rhythmically (technical term “modulated”). AM is traditionally the radio system used by truck drivers
worldwide for CB radio. The low background noise is advantageous if for instance in low interfering diesel trucks
squelch is left open during standby operation. A disadvantage is the lower communication range compared to FM
(because of higher allowed power in FM) or even SSB and the varying volume between near and far stations.
In FM mode the transmission power is always the same when speaking, thus hardly any interferences from other
units are to be expected in this mode. Instead the frequency of the unit varies during speaking and for this reason it
is called frequency modulation. Advantage is a greater range compared to AM and a constant volume of near and
far stations as well as a clear modulation sound. Some noise is a disadvantage and can be heard with weak or
missing signals. In FM mode it is basically not possible to leave squelch open in standby operation. FM is used on
the 10 m Band only for operation via repeaters.
SSB (Single-SideBand) marks the height in the development in long distance traffic voice transmission. SSB mode
avoids the disadvantage of low range of AM and concentrates all transmission power on a minimum frequency
width with speech pauses reducing the output to nearly zero. For reception a special circuit ensures that the
transmission of cut off “sidebands” and the “carrier” are again restored. This achieves an enormous increase in
range compared to AM and FM. Not only does the transmitter reach further, also the receiver is substantially more
sensitive through the halved bandwidth. All this has to be paid for with the disadvantage of a very fine tuning being
necessary for reception and that there is a higher risk of interferences of nearby devices during transmission. Due
to the necessary fine tuning of the receiver with the “Clarifier” (11) the use of SSB in moving vehicles is a problem
and can distract in an objectionable way from the traffic, similar to using a mobile phone. SSB is rather a mode for
base stations. This is also the reason, why today only experienced radio operators use SSB – you really have to
train and develop a sure instinct for the correct setting.
USB and LSB
In SSB mode a conventional channel is divided in two halves: the so-called upper sideband (USB) and the lower
sideband (LSB). Both can be used independently. Example: you transmit 28.500 MHz in USB. In reality you use

9
for speaking only the frequencies upward of 28.500 to approximately 28.503 MHz, while in LSB mode the
frequencies below 28.500 MHz to approximately 28.497 MHz are used. Both sidebands are mirror-inverted and
this is why receiver and transmitter must be set to the same sideband. Otherwise you only receive some
incomprehensible gibberish.
Set Transmission Power
Your unit comes with continuously variable transmission power. In normal state the control knob PWR (14) should
be set fully clockwise. In this setting you achieve max. 25 Watts in FM and SSB and about 7-8 Watt in AM. Turn
counter-clockwise to reduce power to approx. 100 mW. This should be done if you want to be heard only in the
absolute near proximity.
By the way: it also reduces the general electric smog level if the transmission power is set as low as just needed
for the radio link!
How to Receive SSB?
As receiving station of course you do not know in which sideband your outstation is currently transmitting. That the
outstation is transmitting in SSB mode is easily found out, because the “squawking noise” is very different from FM
or AM signals. First receive in USB. Carefully tune through the Clarifier. If you hear a “Mickey Mouse like” pitch
carefully fine-tune to a more comprehensible pitch. If this is not possible try the other sideband LSB.
You will need some experience until you clearly understand your first dialog partner in SSB mode. But surely you
will soon be rewarded by your first DX (= long distance traffic) connection.
Use Frequency Memory
Frequently used frequencies or channels can be saved and retrieved including the corresponding mode by
pressing MSAVE/MLOAD (10) in 5 station memories. The settings are not erased during temporary power failure,
as the unit works with low power backup technology.
Enter Frequency
Set the desired frequency. Press the buttons FUNC + MSAVE + station memory (1-5) in sequence to save the
frequency.
The display shows an “S” for “SAVE” after pressing FUNC + MSAVE.
Recall saved Frequency
Press MLOAD and the station memory (1-5) to access saved station memories (the display shows an “L” for “Load
memory” after pressing MLOAD).
CALL Channel
Station memory 2 is especially easy to access by briefly pressing 2 (CALL). As a conformation for this preference
channel the display flashes as long as the channel is selected. To leave the CALL channel briefly press 2 (CALL)
again. The default call frequency is 29.300 MHz. The last used channel is displayed again.
Scan Mode
Scanning allows you searching the band beginning with the last frequency or channel. In does not matter if the last
frequency was a station memory. After finding a signal in scan mode this channel is monitored for maximum 8
seconds, unless the signal disappears earlier. In this case scanning starts again until the next signal is detected.
Start and Stop Scanning
Press the SCAN (9) button; scanning starts. You can stop scanning by either pressing the PTT button or pressing
the SCAN button again.
Important: Scan mode uses the squelch setting as switching criteria. Set squelch first to the value for the scanner
to stop at a used channel. Scanning is not possible with open squelch: This state is detected by the CPU as a used
channel and it switches in 8-seconds cycle to the next channel.
Reverse Scanning Direction
You can change the scanning direction from up to down or vice versa at any time. Briefly turn the channel selector
in the desired direction or use the UP and DOWN buttons on the microphone.

10
Last Channel Recall (LCR)
If you were scanning or listening a lot to other frequencies you may want to return to your last transmission channel
by pressing a single button? Press the LCR (6) button to return to the last channel you used for transmission for
more than 3 seconds.
Noise Blanker
A noise blanker is a circuit to fade out or limit temporarily pulsating interferences. As the 10 m band is especially
effected by noise from electrical appliances and vehicles your unit is equipped with a corresponding function to be
engaged in AM and SSB modes.
The noise blanker is activated/deactivated by pressing FUNC and NB (5).
Simplex- and Repeater Operation
With the default settings you can start to communicate point-to-point on simpex channels. In the years of high sun-
spot activities you can reach communication distances of several 1000 kilometers. A good indicator for long
distance conditions are the repeater stations in Europe and USA. Most of the repeaters can be found in the upper
band segment just below 29.670 MHz.
Repeater settings
You can reach repeaters in Europe and – under good propagation conditions as well in USA. For repeater
operation it is necessary to shift your transmitting frequency to the uplink frequency of the repeater, while you listen
on the downlink frequency. For example you hear a repeater on 29.670 MHz. Then the suitable transmitting
frequency for this repeater is 100 kHz lower at 29.570 MHz in this example.
Activate the Repeater Shift
Press first FUNC and then SHIFT (9) in sequence. +SHIFT will appear in the display. Press both buttons once
more, then you obtain –SHIFT.
Factory default value is 600 kHz (Far East). In Europe we use 100 kHz, so you should change the setting from 600
kHz to 100 kHz.
Change Shift Value
The frequency shift can be varied between 10 and 999 kHz. Use again the sequence of FUNC and SHIFT, but then
hold the SHIFT-key more than 3 seconds pressed, until the display shows 600.
Now you can use the rotary channel knob or the UP / DOWN- buttons at the microphone to adjust the shift value
to the European / USA standard value 100 kHz.
Confirm the setting be pressing the PTT button or the FUNC button.
Sound Filter
The receiver comes with a switchable sound filter, what is especially useful for noisy signals, as it attenuates the
aggressive high sounds, making the sound easier to listen to. Deactivate this filter by pressing FUNC and LOW (8).
Activate/Deactivate Key Tone
Turn the unit on while pressing the transmission button (PTT on microphone). In this way you toggle between
activation and deactivation.
Interesting Facts Relating to the Technical Data
Storage and Backup of Set Data
The radio is no longer equipped with a lithium battery, but uses the low power backup technology. For this reason
data are only erased after a long time.

Maintenance and Programming
The following references are exclusively for expert service staff. Program settings are only permitted for authorized
users and for commercial export in countries allowing the corresponding versions.
No responsibility for damages and consequential damage caused by incompetent or not expressly by Albrecht
explained programming steps and other interference. The end user warranty generally expires with opening the
casing. Only use Albrecht specialized dealers for modifications during the warranty period!
Reset to Default and Deleting All Memory
A general reset to factory settings is possible by disconnecting from power supply and briefly pressing the reset
button on the separate small internal SUB Board after removing the speaker cover (visible after removing the
cover). Perform this reset when experiencing malfunctions. There are inevitable external interferences, which may
block the processor or lead to certain functions being not or not correct performed. The interferences can be
caused by electric storms, overvoltage, to great HF irradiation and the like and are generally easily fixed by reset.
However, reset also deletes all station memories.
For Amateur radio the factory jumper setting CON1 on the internal Sub Board is permitted for all countries
(28.000 to 29.700 MHz).
Other settings are permitted for amateur radio, but maybe restricted in some countries. The user needs a valid
amateur radio license. Even amateur radio operators are only allowed to use frequencies allocated for amateur
radio, even if a device can be programmed for further frequency ranges. You find the permitted jumper setting for
amateur radio operators at http://www.hobbyradio.de/Amateurfunk under AE 485S. Please note that our
Declaration of Conformity expires with modifications.
