Miulla on tossa hubissa virtakytkin jokaiselle portille. Käytin molemmat tikut pois päältä. Ensin se "hukassa" oleva ja sitten toi jonka Gqrx löytää. Menee silmät solmuun noita rivejä selatessa, mut toivottavasti sattuu rivit kohalleen.

Jännä et noi näkyy tunnistettavilla erilaisilla nimillä ohjelmissa, siis näkyi, mutta tossa lokissa näkyy vaan vastaanottimen ic-lutikka joka on sama molemmissa. Hiukkasen hankaluuksia erottaa ne toisistaan. Jos ton mikä Gqrx:ssä toimii, irrottaa niin toi toinen ei näy sittenkään. Ei edes Gqrx:än boottauksen jälkeen.
Jollain täällä oli tikku olemassa, niin jos kiinnostaa kokeilla kuuntelua, on helpoimmin kuultavissa noi lentoyhtiöiden tekniikan taajuudet. Miulla kuuluu kajaanin ja tallinnan väliltä suurinpiirtein kaikki lentokoneet. Maa-asemat ei miulle kuulu. Pääkaupunkiseudulla saa jotain kuulumaan todennäkösesti vaikka henkaria antennina käyttäen. Ei hajoo mitään jos nyt ei kaapeliverkon liittimeen tökkää vastaanotinta kiinni. Tuskin hajoo sillonkaan.
Norra tekniikka 131.443MHz am-modulaatio
Finnair tekniikka 131.550MHz am-modulaatio
Lentotekniikka helsinki 131.600MHz am-modulaatio
Radioliikenne sisältää kyselyitä merkkivalojen palamisesta aina koneen tankkaustarpeisiin. Liikennettä ei oo hirveesti, verrattuna esim. tampereen aluejohtoon(sektori M 132.325MHz am)
Taajuuksia saattaa joutua hienosäätämään jonkunverran johtuen vastaanottimesta, mut se voimakkain signaali näkyy piikkinä Gqrx näytöllä.
muoks:
lisäsin tekstiin("koodi") tyhjät rivit löytymisen helpottamiseks.
muoks 2:
Kokeilin uudestaan toimiva tikku kokoajan pois päältä ja kytkin toimimattoman. Lokin loppu ei muuttunu, joten huonolta vaikuttaa.
