Hello there. RFMap is currently offline. My server finally bit the dust, and I'm back in Australia until the end of April.
For updates please follow me on Twitter.
If you're interested in my Software Defined Radio work, I'll be presenting in Sydney on the 15th (Manly-Warringah Radio Society), 16th (UNSW) and 17th (Ruxmon held at Google Sydney) of April.
Meanwhile, visit the rest of spench.net.
(If you came here from "The electromagnetic spectrum", or expected to see my early RF spectrum measurements, click here. You should also definitely check out RF Map, which is most likely NOT offline, and the rest of the site.)
