FYI if you have an iPhone or iPad, Signal GH from generally helpful software still works great. I used it 2 weeks ago with my ipad to tune an antenna in an attic. Works perfectly. The only problem is the FCC is changing all this spectrum around and stations are getting real screwy with channel name, fake ID's etc..... We will have to wait a few years until all the dust settles with the changeover.
