\sec Current radioastronomy problems
 
Nejprve z pohledu radioastronoma je podstatné, že jej v převážné většině zajímají signály přírodního charakteru, přicházející z okolního vesmíru. Tedy většinou ani nechce, aby měly nějakou spojitost s naší civilizací.
From radioastronomer point of wiev its important radioastronomy has interest in primarily natural signals from surrounding universe. Radio astronomy do not have interest in terrestrial civilisation made signals.

To je často velký problém, neboť na Zemi touto dobou existuje velké množství vysílačů, které pokrývají prakticky celé dostupné elektromagnetické spektrum a vytvářejí tak nepřebernou směs signálů, která se nejenom pro radioastronoma může stát nepřekonatelným problémem. Z tohoto důvodu byla již od počátků rádiového vysílání snaha udržet nad obsazením spektra určitou kontrolu a jedním z důsledků této snahy je například <a href="http://www.ukaranet.org.uk/basics/frequency_allocation.htm">tabulka přidělených kmitočtů pro radioastronomii</a>. Bohužel z mnoha důvodů nelze říci, že by tyto kmitočty byly dostatečně kvalitně čisté pro sériózní pozorování. Z toho vyplývá důležité zjištění, že v současné době nelze postupovat stejně jako v počátcích radioastronomie. A tedy i experimenty, vedoucí například k objevu reliktního záření nebo pulzarů, nelze v původní podobě zopakovat s uspokojivým výsledkem.
 
This is big problem because at this moment many terrestrial transmitters are active and all this transceivers made desnse signal mictrure which can cause troubles not only to radioastronomers.
In consequence of this, there exist a tendence to control radiofrequency spectrum. As result of this controling the radiofrequency allocation table was created \url{http://www.ukaranet.org.uk/basics/frequency_allocation.htm} This table consist special bands allocated to radioastronomy use. But from many ... this bands are not clean enough for directly use in radioastronomy observations. As resul of this we cannot work by same way as radioastronomers in beginnig of radioastronomy. Many experiments namely, reliktive radiation detection and pulsar detection cant be realised in original form with satisfactive results.

Důkazem může být například projekt RadioJOVE, který přes svojí správnou ideu v dnešním civilizovaném světě jednoduše nefunguje. Důvodem jeho nefunkčnosti je právě přítomnost elektromagnetického smogu, který je řádově silnější, než Jupiter. A z praxe například i okolo světelného znečištění nelze očekávat nějakou radikální změnu k lepšímu.
