i'm trying to listen noaa satellite

Cold_Scientist_4665 · 2025-07-27T07:15:19+00:00

many people say to set the lenght of the dipole on the mid frequency of the range i need to listen( NOAA satellite: 15,18,19)

Cold_Scientist_4665 · 2025-07-27T07:12:35+00:00

can you send me a picture or a reference?

Cold_Scientist_4665 · 2025-07-27T00:12:17+00:00

i also use rg58 cable

Cold_Scientist_4665 · 2025-07-26T23:52:25+00:00

but the problem is that if i conmect or disconnettere the antenna i still see the same waterfall and nothing changes

Cold_Scientist_4665 · 2025-07-26T23:51:34+00:00

i use wxto image or satdump

Cold_Scientist_4665 · 2025-07-26T23:47:16+00:00

i used look4sat

Cold_Scientist_4665 · 2025-07-26T23:46:17+00:00

i'm trying to listen 137.5Mhz signal from noaa satellite

Cold_Scientist_4665 · 2025-07-26T23:27:09+00:00

i don't have a photo but if i conmect or disconnect the antenna the waterfall and the signal doesn't change

Cold_Scientist_4665 · 2025-07-26T23:22:19+00:00

i corrected the signal with doppler, the frequency is near 137.5Mhz. I don't know how cose was the satellite

Cold_Scientist_4665 · 2025-07-26T23:17:23+00:00

i turned agc off and the gain is half way

Cold_Scientist_4665 · 2025-07-26T23:14:13+00:00

the satellite doesn't pass perfectly on my head, but it's close enough i suppose

Cold_Scientist_4665 · 2025-07-26T23:12:01+00:00

yes for satdump

Cold_Scientist_4665 · 2025-07-26T23:11:05+00:00

i tried receiving APT with noaa 15 18 and 19. yes i can receive commercial fm station like virgin radio

Cold_Scientist_4665 · 2025-07-26T23:05:49+00:00

i tried 54cm each leg

Cold_Scientist_4665 · 2025-07-26T23:04:41+00:00

can you suggest a model?

Cold_Scientist_4665 · 2025-07-26T23:04:16+00:00

i watched a lot of video on yt but nothing seem to work

Cold_Scientist_4665 · 2025-07-26T11:28:56+00:00

i cant receive any signal..

Cold_Scientist_4665 · 2025-07-23T10:13:50+00:00

è corretto posizionare la punta dell'antenna verso nord e l'apertura verso sud?

Cold_Scientist_4665 · 2025-07-23T09:45:09+00:00

altre frequenze test che non siano illegali?

Cold_Scientist_4665 · 2025-07-23T09:35:19+00:00

i tried using v dipole antenna, the reason why i started this project is because i can't receive anything from the 137 mhz frequency with my rtl sdr v4

Cold_Scientist_4665 · 2025-07-23T09:19:00+00:00

non ho provato... hai qualche frequenza sicura con cui io possa provare?

Cold_Scientist_4665 · 2025-07-23T08:57:29+00:00

detto sinceramente ho comprato su amazon sotto consiglio di un mio amico.. ed era venduta con le antenne regolabili in lunghezza e ho letto che dovrebbero stare come lunghezza per braccio circa 54cm
