Alright people, this thread was brought about by another about the UVB76 radio transmitter in Russia throwing off code and other assorted weird shit. If you want to check out that thread, it's here:
http://www.ar15.com/forums/t_1_5/1603400_UVB_76_is_giving_off_code_again____.html Okay, now that that business is out of the way, in the UVB thread, someone was kind enough to post a web based shortwave radio and I've spent the better part of an hour exploring it. It can be found here: websdr.ewi.utwente.nl:8901 Now during my exploring, I located some fun stations, and listened in on some Europeans having a quite animated conversation with a guy in Spain. On another frequency, I found some German guy playing guitar like a madman. He can be found at 174.00 kHz, AM bandwidth, right now. It can take a little bit of practice to figure out how wide you need your bandwidth, and where you need it, but all in all, you're all pretty smart. So, since the power of ARFCOM is the massive amount of people, and if you're not doing anything especially interesting, check it out! And post any interesting frequencies. |

So apparently there are these $20 dongles… And a $50 upconverter to get lower on the band… Just saw 'em online and decided to gamble. Maybe it'll be cool.  It will be. I have a dongle and a nooelectric upconverter. Believe me you will be amazed. You will literally have a 0-1700 MHz all mode communications receiver for less than $100 and I'm not joking. I mean FM, Wide broadcast FM, Upper Side Band, Lower Side Band, AM and even P25, TRBO, NEXTEDGE, Provoice etc... all if you pipe it to DSD+ and that doesn't begin to include all the HF band digital modes if you use something like Sorcerer software. For less than $100 you will have something that would literally cost tens of thousands of dollars a few years ago if you could even get a hold of it. If you use the fast scanner plugin for SDR# or the modded SDR# release you can actually set it to reaction tune to the peak transmissions. I did this with the 118 - 136 air band. It was freaking amazing. It would jump from transmission to transmission automatically while logging the frequencies it found to a text file and even recording if you set it to. |

Yea, the more I read, the more I'm blown away at what this appears to do. Final total was a hair over $120, but I picked up a scantenna and a buttload of antenna adapters for this and other projects while I was at it. And when it gets here I'll have a good few days to myself to work on it, because my wife aint talkin to me for a while once she sees what's going on the roof.
