Frequency Electric Field Magnetic Field Power Density Averaging Time
300-1500 MHz = f/1500 mW/cm² averaged over 30 minutes where f = frequency in MHz
Thus
0.5605 mW/cm² is FCC’s Public MPE for the 840.75 MHz frequency signal observed
This equals 0.0005605 of received Watts by spectrum analyzer
43 dBm = 0.000000050118723363 Watts average signal received while
42.5 dBm = 0.00000005623 Watts is peak signal received
Since it is uniform can this come from space?
How many watts does a telecommunication satellite use?

Geosynchronous communications satellites have a range of power levels. Currently, small ones consume about 2 kW, large ones about 20 kW.
Low Earth orbit communications satellites are typically in the range of 1 kW. Modern satellites use triple junction solar cells. There are 3 separate p/n junctions. One captures blue light, one red, and the third gets an intermediate wavelength. These cells convert almost 30% of the solar energy into electricity.
Most satellites these days use lithium ion batteries. When the satellite is in sunlight, the solar cells provide power for the payload plus electricity to charge the batteries. When the satellite is in darkness, the batteries supply all the power.
It seems that space satellites are too low powered and/or are too far away to be the origin of this radiation emission.
Here are some facts underlining the most likely space candidate:
Geostationary orbit (GEO), which is 36,000 kilometers and which is the altitude of most satellites, while
The International Space Station has by far the largest power output potential in orbit- further
International Space Station's Solar Array's Total Continuous Power = 120,000 watts or 120 KW while
Stable low earth orbit (LEO) minimum, which is 300 kilometers for any satellite one may use
The International Space Station LEO= 408 kilometer-which is very close to minimal orbit altitude but too far and low powered.
However according to the inverse square law of the power falloff of radiation using a dish antenna focused at 300 KM on the half of the Earth's surface it would take a 1500 KW transmitter orbiting at 300 kilometers and even then only 0.000000050118723363 Watts would be evenly spread on the Earth's surface directly below and which is far less than the 0.00000005623 Watts which is maximum signal received over this 10 mile sample radius.
Therefore it is highly unlikely that this signal comes from space unless unless of course it is from some secret installation.
Below are some of these possibilities:
Microwaves are called the electromagnetic waves produced by electronic oscillators of human technology, with frequencies higher than those which can be reflected by the ionosphere (thus higher than ~ 200 MHz) and up to the low limit
of infrared (~ 300 GHz).
The microwave array transmitting at the narrow bandwidth of 2.7 MHz-10 MHz @ 5.1 GW near Denali in Alaska, HAARP can create a signal more powerful than our early nuclear early detection system PAVE PAWS (@582.4 KW peak/face), the one near Marysville, CA less than 500 miles away from this sampling area, but it happens that Temecula is >10 miles out of its PP's maximum spread East thus it would have to then bounce off of Ionosphere at some 80-1000 km above Earth by using HAARP system in far away Alaska. Judging from the current satellite pictures of the antennas in Alaska they have not started yet transmitting anywhere near the 840.75 MHz frequencies, thus both of these most powerful 2 of secretive transmitters remain unlikely this mystery signal's origin especially since this mystery signal is at a higher frequency than can reflect well off of the ionosphere.
Whereas the manufacturer of my spectrum analyzer RF Explorer has concluded that this is an artifact from improper DSP FFT filtering in their equipment, I still find my other spectrum analyzer in the form of an SDR Spyverter shows this same spike at the 840MHz zone (see second video in this blog) leading me to think it is not an artifact but a real signal.
This then leaves either a local GSM/CDMA cell or utility communication mesh network the only likely known candidates that can be adding to this particular frequency's MPE threshold - a signal that is for a fact felt by those who are already sensitive and can receive this signal - as it's ideal antenna length is 14" ubiquitously present in 50 ohm impedance human body bones.
It is very important to emphasize that all (wireless) telecommunication devices emitting microwaves, emit extremely low frequencies (ELF) as well since this is absolutely necessary for pulsing and modulating the RF carrier signal in order to be
able to transmit increasing amount of information (Tisal 1998; Hyland 2000 Hillebrand 2002; Tuor et al. 2005; Curwen and Whalley 2008). In other words, exposure to EMFs from mobile or cordless phones, Wi-Fi and other wireless communication devices, is simultaneous exposure to several frequencies both RF and ELF. It is suspected that the ELF emissions included in all telecommunication signals are those more responsible for the biological/health effects, and not the carrier RF signal itself (Panagopoulos et al. 2015b).
Are there any other viable contenders escaping my purview that could be the origin of this powerful and continuous RF frequency such as filtering issues with the 2 spectrum analysers, Boingo, Google Loon or even drones? Let me know by responding to this blog entry - Thanks!
