I collected a Spectrum Analysis of 1680-1683MHz on January 1, 2017 after observing extremely strong signals in my home on New Years Eve. Being a former Radio Frequency Engineer, I have a little bit more experience than most in this area. Part of my job was to collect these types of Spectrum Analysis for commercial cellular/wireless companies. Though my equipment is low-end, it's competent enough to perform a measurement of this type for preliminary purposes. In my experience, I would have accepted these results in a professional environment if i were a Wireless Engineer reviewing this. Real-Time Spectrum Analysis is one of the most valuable tools through which to observe the "behavior" of a signal and make evaluations on what it could potentially be.

I'm looking for objective eyes on this because I'm not only observing these signals but feeling physical symptoms when they are strong. This is a sensation, similar to excessive EMF (electromagnetic frequency) exposure. I used to be a Cellular Technician and was exposed to more Radio Frequency than most people during that time. It isn't immediately toxic like nuclear (ionizing radiation) but it definitely makes you feel sick and can cause real physical damage under select circumstances. The damage from non-ionizing radiation (cellular/wireless frequency and others) would come from extended exposure to high levels at close proximity. The people who experience this the most would be tower crews who stand on the tower platform all day while they are powered up. If they stand behind the antenna, it's relatively safe but if they place their head in front of the beam, they will feel sick within minutes.
Signs of this would start with fever like symptoms in my experience and it feels like your brain is boiling. Nausea will set in within minutes. Because what is happening to your body is basically a slow cook sensation. You are heating up the tissue in your body rapidly. So it's like being cooked in a Microwave Oven but without the box that makes the signal bounce around inside. So you'd have to be right in the line-of-sight or main beam to really feel this to any significant degree. If you stared into a high power antenna or stood in front of it for an hour or so, it wouldn't be abnormal for you to develop cataracts or sterility prematurely. So we know that radio frequency can be dangerous if used in a weaponized fashion. It just doesn't give the same signs as a bullet. It can be used to slowly kill or control someone who is in close proximity to it. No doubt. I can stand by that assertion after two decades of working around this.
So I don't know what the deal is here entirely, I'm just trying to figure it out. In the process, I am feeling some pretty intense negative physical sensations that correlate to this. Even with the time I spent in the wireless industry, I'm kind of at a loss for what I should do here. The FCC is more or less the enforcer of the companies that place the technology online. They aren't here to help the citizens as much as manage the spectrum and frequency needs of commercial and military organizations. If there is anyone who is competent in this field and would like to exchange data, I'm happy to share what I've learned.
Thank you for reading.

What would you recommend for real time spectrum analysis? Is there a phone app to use it's signal processor up to its range?

I don't recommend using smartphone apps for anything but playing around with. They aren't a reliable measure for a raw signal analysis which is what you need here. Smartphones are typically equipped with quad-band radios that are limited to passing only what the networks are equipped to see. These range typically, in the US - 700, 850, 1900, 1700/2100aws MHz) for cellular tower communications and then you can pass the Wi-Fi and Bluetooth signals which run in those 2.4-2.5 GHz ranges if I'm not mistaken. So even if the app can run independent of the network settings they are limited to whatever the phone is. You'll need a "Spectrum Analyzer" to replicate my results. I have an RF Explorer 6G Handheld Spectrum Analyzer with iRFExplorer Freeware (macOs). This cost me about $350 USD and would be considered reliable. Important thing to remember is that your Smartphone is just a "slave device" unless you have jailbreaked or side loaded an app with a modified ROM (Android OS/Core Firmware on phone). Unless you do that, the phone will always do what the network (towers/base stations/cellular network) tell it to do. So it's not a "raw" signal measurement. It's just measuring whatever the network allowed it to. Hope that helps.

Looks like it's connected to an external dongle or USB style spectrum analyzer. Whatever works for you personally is fine. I am using a hardware Spectrum Analyzer with it's own display and the option to connect to an external application for cleaner screenshots. No external software is needed to use my unit (RF Explorer 6G) but it will produce better screenshots if you have the software. My configuration is just different so go with what you feel comfortable with. In this case, you are polling your data from the USB stick or dongle, if I am understanding the photo correctly, so you aren't limited to the smartphones' radio's capability. So whatever I said about the frequency limitations would not apply to your config. Yours would be limited to whatever the USB stick Spectrum Analyzer (?) is spec'd out for. I'm just guessing based on the frequency you are scanning (433MHz) which in the US, typically isn't used by commercial wireless providers and not usually capable of being passed by the smartphones radios. I have seen that frequency in other circles though. I think it's used for radio control drones and car remotes in addition to other things, assuming you are based in the US.

Below is a method of procedure that can be replicated by newbies. The only thing I didn't cover in this is that you'll need to play around with Average/Max/Max Hold settings for a little while to see what signals are around. It just takes practice. You'll see how they differ when you have the device in front of you. More details are in the blog post below. Hope that helps.
