1) Message boards : Cafe SETI : Ok, can someone help out this newcomer? (Message 400583) Posted 18 Aug 2006 by JCY Post: I can TRY to invent this sort of star-noise scanner, but I won't be able to do it alone. I imagine there'll be an inscrutable amount of resources required here, and probably expensive resources at that (unless everything I use is from a scrap yard or old unused appliances). And atop of that, I think I might possibly be a tad bit ignorant on HOW to construct a thing of this stature. I mean, if I had a group of people to help me, I think the chances of its completion will look very positive, but I would need people who have experience in this kind of thing. I know for one, I would need a dish, a fairly large one, 2 or 3 work computers, a radio transmitter, audio frequency amplifiers, and a software program for all of this to work through. I would also need something that would keep certain waves from interferring with the ones I want to recieve. Is there anything else anybody could add to this list that makes this possible, or tell me how to assemble these things correctly, cuz I don't want to "accidentally" invent a type of EMF bomb or overpower an electric generator!

I had no idea what that data on the far top right in measurements was referring to. Well, when I had a signal (previous to what you told me) of 1.420 GHz I always wrote it down when that signal looked strikingly similar to another, unaware if it was passing over the same area or not. Now that I know where to look at the dish alignment, I believe I'll be able to recognize a reoccuring signal if it passes over the same area. I originally had an idea to set up my own dish (either constructing it from scratch or use one from a scrap yard), I wanted to find a way to be able to recieve the radio signals from stars and be able to hear their cosmic noise, to see the differentiation between them. I might set up a new thread on some pointers, but do you know of a program on the net that would allow a person to hear that cosmic noise already?

(Message 398000) Posted 15 Aug 2006 by JCY Post: Actually, good thing you reminded me, cuz there was something I saw, I don't know if this is "specifically" what we're supposed to be looking for, but..... my base frequency has been staying at around 1.420 GHz lately since Apr 11 to 15th 2006 (the 15th today as I speak). They said the last time they had an unknown signal was at 1.420 MHz, I think it was in 2003.......... I mean, does this mean anything, or is it just wishful thinking on my behalf?

But I think I understand it alot better now, they said the four things we are seeing here is; spikes in power spectra, Gaussian rises and falls in transmission power (possibly representing the telescope beam's main lobe passing over a radio source), Triplets (3 power spikes in a row), Pulsing signals that possibly represent a narrowband digital-style transmission. I got this info from http://en.wikipedia.org/wiki/Seti%40home I know it's hard to understand what these things mean to some (myself included), but I guess I can better explain it using what wikipedia.com has shown me. power spectra - In physics, the signal is usually a wave, such as an electromagnetic wave, or an acoustic wave. The spectral density of the wave, when multiplied by an appropriate factor, will give the power carried by the wave, per unit frequency. This is then known as the power spectral density (PSD) or spectral power distribution (SPD) of the signal. The units of spectral power density are commonly expressed in watts per hertz (W/Hz) or watts per nanometer (W/nm) (for a measurement versus wavelength instead of frequency). Although it is not necessary to assign physical dimensions to the signal or its argument, in the following discussion the terms used will assume that the signal varies in time. Gaussian - a beam of electromagnetic radiation whose transverse electric field and intensity (irradiance) distributions are described by Gaussian functions. Many lasers emit beams with a Gaussian profile, in which case the laser is said to be operating on the fundamental transverse mode, or "TEM00 mode" of the laser's optical resonator. When refracted by a lens, a Gaussian beam is transformed into another Gaussian beam (characterized by a different set of parameters), which explains why it is a convenient, widespread model in laser optics. The mathematical function that describes the Gaussian beam is a solution to the paraxial form of the Helmholtz equation. The solution, in the form of a Gaussian function, represents the complex amplitude of the electric field, which propagates along with the corresponding magnetic field as an electromagnetic wave in the beam. Triplets - I believe this is referring to 3 power spectra spikes in a row pulsing signals - A rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. AND/OR A rapid change in some characteristic of a signal, e.g., phase or frequency, from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. I'm guessing what we're seeing is a variety of waves and fields we're both creating ourselves and sending out AND at the same time reading natural waves and fields, in order to see "something" that recieves these created waves and replies to them OR something that happens to pass through these waves and fields alone, affecting them to a certain degree.

(Message 389902) Posted 6 Aug 2006 by JCY Post: What would we need to look for in the base frequency (if the base frequency is what we're looking at) which symbolizes a "strange" or "unknown" reading? I'm still a lil fuzzy on detecting what we're looking for, I'm pretty new to this whole thing. Can anybody help me out on this?
