6.2.1.5.1.1 Adjusting Bearing Value Averaging Memory: AVERAGING
Common Remarks:
The bearing system processes about 750 bearing values a
second. Depending on the quality of the received signal (field
strength, modulation), the single bearing results may be varying significantly. The single bearing
values are being averaged with a special algorithm by the DCU´s electronic. The depth of the
value memory (number of used single bearing values) may be adjusted in submenu SETUP -
BEARING - AVERAGING (see Fig. 52).
To be considered:
- the greater the averaging level  the greater the depth of memory
- the greater the averaging level  the more stable the display
- the greater the averaging level  the higher the sensitivity
- the greater the averaging level  the more drag error!
So, the adjustment has to be a compromise between a stable display and the drag error.
With a high averaging level the sensitivity becomes a bit better (with deactivated squelch), but
the display is getting rather inert, thus complicating the normal working with the system.

ATTENTION
Setup adjustments in this menu are influencing the bearing result. Faulty setups
may lead to wrong bearing results, and it may not be possible, to recognize this
error immediately. In case of doubt don´t hesitate to contact the service or the
service hotline of RHOTHETA.
