It's a nice, portable (and relatively inexpensive) spectrum Analyser.
Works like a champ! I can actually see the ENTIRE UHF spectrum in one screen, or zoom in on a single channel.
Thanx to this device, I was able to adjust the UHF antenna direction a bit more precisely. Much better than the Analogue meter.
I can also see WHY channel 10 is gone. Pilot is nice and strong, but the rest of the signal is down in the dumps. Still don't know why this changed from this summer, but at least I now have a visual!

Thanks for the report. It sounds like it has been helpful for you. Which model did you get, the 3G Combo?
I did a terrain profile for WTNH:
That is a difficult path for the signal. It depends upon atmospheric refraction and diffraction at the mountain peak to get to you.
This is the tvfool version of the profile:

I think it would be worth the trouble to tilt the front end of the 30-2475 up, or even replace it with the 30-2476. The polarization of the signal is already messed up because of the diffraction at the mountain peak.
