Hey all - so I'm not new to this hobby by any stretch however I am starting to get more interested in diving deeper in. I have been a casual listener off and on for many years. That being said, I'm currently using a Radioshack PRO-106 with a Discone antenna mounted aprox. 20-25 feet off the ground. It is connected to my scanner via 50' of RG6 quad shield.
Now with some basics out of the way - on to my questions. I'm looking to "clean up" some noise both in general as well as in some signals. I'm sure I have interference I'm just not sure where to start with it.
My first concern is the FM radio band 88-108. I have 3 stations broadcasting from about .4 miles away at 250 watts (94.1, 98.5, 103.1) they sit about 300 feet above me so pretty good line of sight. I also have 3 more stations broadcasting within about 3 miles from me at a higher elevation 1300 feet above me and at a higher power - 580,450, & 390 watts. (91.9, 99.1, 106.3).
Lastly - I also have an AM station close by also about .4 miles squirting out 1000 watts on 1400Khz
Of course there's my electronics, wi-fi, neighbors, etc as well. I live in a house on a .25 acre lot in a neighborhood in a small town.
SOOOO, sorry this is getting longer than I intended but my questions are basically are these stations possibly causing me some interference and if so would it only be an issue on adjacent frequencies or could they be causing issues across the board? This is where I haven't much depth of knowledge.
Bonus questions - I also receive some strong signals 3-4 bars on my scanner, but there's much static over the modulation and hard to hear. Is there any way to clean that up? Is it possibly RFI on my end?
Lastly - I'm thinking of picking up a Nooelectric SDR dongle to play with, might this also be used to find out some problem frequencies where i'm picking up interference and those pesky spurious RF emissions.
