LED brightness, ADR search, Oscillator frequency

Initial settings

LED brightness

Here you can increase the brightness of the LED display. This may be necessary, for example, if bright light is beaming down on the receiver and the LED displays are no longer easy to read. In this case set the display to “High“ setting.

Factory preset: Low

Remote control handset

The receiver contains command sets for Kathrein remote controls with both 24 and 26 keys. The remote control included with the receiver has 26 keys and this is the predefined command set on delivery. Hence leave this setting unchanged as

“26 keys“ (factory preset).

ADR search

In this menu entry the criteria can be set up for the automatic station search for

ADR radio programmes.

ADR radio programmes are currently radiated only from the Astra satellites in the lower frequency band (low band). The above setting is already set up accordingly. If you want to switch off the automatic search run, set the “Search run” menu entry to “OFF”.

Save the setting with the key (press twice).

The search run starts when the receiver is switched into standby from “ADR radio” mode. After the search run the receiver switches to standby.

Oscillator frequency

The satellites radiate their programmes in a frequency range that satellite receivers are unable to process. In the receiving system (known as the LNB - Low Noise Block converter or LNC - Low Noise Converter) this frequency is converted into a lower frequency that can be processed by satellite receivers.

The satellite transmission frequencies lie in the following ranges:

10700 ...	11700 MHz	Low-band
11700 ...	12750 MHz	High-band

The receiver‘s input frequency range, however, lies in the range: 920...2150 MHz

Conversion of the higher frequencies into a lower frequency is achieved with the aid of the oscillator frequency (LO frequency). Various oscillator frequencies are used for the conversion according to the satellite frequency range and type of sys- tem.

For Astra and Eutelsat receiving systems, this is generally 9.75 GHz (9750 MHz) for the lower frequency band (low-band) and 10.6 GHz (10600 MHz). for the upper frequency band (high-band). Older receiving systems still operate in the low-band region with 10 GHz oscillator frequency.

The receiver calculates the frequency onto which it needs to tune by subtracting
