Thankyou Andy for your help. Unfortunately for me, I cant see/hear much on various bands. I can hear local FM Radio broadcast, AM radio and see plane tracking dump1090 but thats as far as I go.
a. APRS: I try to follow steps per https://www.sdrplay.com/docs/SDRuno_APRS.pdf but I see no activity. Please see the screenshot. Not sure if this is my Antenna (Tram 1411 Broad Band Discone) that is inside or I am trying a wrong frequency, or mode. I live in Austin. TX
b) ACARS: I try to follow steps per https://www.sdrplay.com/docs/SDRuno_ACARS.pdf but again I see no signal. I try other alternative frequency (129.125, 130.025) Again I only see/hear noise. I have attached the screenshot
3) I try to punch in various frequency per https://www.radioreference.com/apps/db/?ctid=2749 for local stations. Again nothing useful. Try all modes AM/FM/LSB/USB etc
d) While I scan various frequencies, I see signals but not sure how to decode those or band to try. Its a large file and I will try to attach next.
Not sure what I am doing wrong- do I need to do some calibration etc (its a new unit), try outdoors or just my lack of information
At this point I am pretty much stuck
Appreciate if you or others can share some insight
