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 5800 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 5800. 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 5800
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.
Channel or Frequency Display
With first use the unit starts in FM mode and channel 9 (27.065 MHz) is displayed. The unit starts in
channel
