NASA VLF Receiver Kit

geigertube writes: "This isnt very new, but after doing a search for 'science' on Shoutcast, I found a streaming feed for a VLF receiver in Huntsville, AL.. Its pretty neat. For some reason its very engrossing listening to the pops and whistles. Via the web page one can order their own kit reciever, (although it wouldnt be that difficult to homebrew one) and listen to the streaming feed. Thanks!"

VLF free band

[drwho]

In case anyone is interested, there is a VLF "free band" at 160-190 kHz in the US. Though output is restricted to 1 watt, and there are limits on antenna length which greatly limit the effective range, communications from hawaii to california have been achieved. Over land, contacts of over 1000 miles have been made with 1900 miles being the record.

Build your own

[PD]

Pick up a soldering iron for once in your life. It's fun, really. Plus the lead in the solder helps you program better.
