What's Your Noise levels?

Lasse Moell

Just saw a post regarding noise levels.. Lets see what others measure. Use 100 Hz BW and read the average level in dBm (I'm using DDUtil), make sure it's an empty spot! Do note time when sample is taken.
---------------------------
28 MHz -132 dBm 2el Yagi
24 MHz -133 dBm   "
21 MHz -130 dBm   "
18 MHz -128 dBm   "
14 MHz -123 dBm   " (ant to northwest)/-117 dBm (ant to southwest)
10 MHz -122 dBm   Dipole
7 MHz -108 dBm     Dipole statics/thunder
3,5 MHz -108 dBm inv L
1,8 MHz -104 dBm inv L

All measured at 21 local, still daylight. QTH just outside of city center (suburban).
Anyone care to share your levels? Do not forget to mention where you are located i.e. city/suburban or rural. Remember increasing RF gain can improve readings!

Indeed, some of the numbers are around -140dBm with the preamp on. However, I wanted to give a good even baseline knowing that I can always improve from that if needed.
