pa0nhc HF filter for use
with SDRconsole |
|
This loop antenna widthstands S(+110dB equivalent
signal input.
When SDRconsole is used, with no input attenuation, during evening hours the
AIRSPY HF+ SDR receiver unti can be overloaded by very strong Long Wave and
Medium Wave Broadcast and FSK signals. Resulting in many false signals in SW
bands. This filter attenuates LW and MW, or all SW bands. Its -3 dB corners are
abt. 1.4 MHz and designed for standard value components.
Black = for real 5% and lossy components.
