Which place in the lower 48 has the least FM radio stations in range?

[Roadgeekteen]

My guess is somewhere in the middle of Nevada.

United States National Radio Quiet Zone?

Beat me to it.  Pocahontas County, West Virginia has the National Radio Quiet Zone surrounding the Green Bank Radio Observatory.  It's almost 110 miles square (a slight rectangle about 13,000 square miles), so that it covers the Naval Radio Station in Sugar Grove over in Pendleton County.  No AM, FM, short wave, VHF, UHF/DTV or even high-pow WiFi.  Complete and blissful radio silence.

For the record, the entire Zone is not totally devoid of radio signals (and there's quite a few transmitting from Sugar Grove).  I've been able to pick up stations from Elkins, Harrisonburg and White Sulphur Springs while inside the Zone, and the one in Marlinton is close and fairly strong along the south edge.  But I've never picked anything up while passing through Green Bank.

So that area wins, but for outside that area, where is it?

There are other places in the lower 48 where the radio will get you nothing but static on every channel.

US 12 in northeastern Idaho is very good for this - over 100 miles from Lolo to Kooskia, with a lot of absolutely nothing in between. And, because the terrain is mountainous and you're in the bottom of a valley, no reception of anything terrestrial to be had for much of the way.

I was always under the impression that K-92 in Roanoke would come in really good in the Quiet Zone. But I don't think I've ever been to the Quiet Zone, though I was probably pretty close just recently. I do remember K-92 making it all the way to Beckley once.

The original question was about FM.  FM doesn't have really great range.  I'm sure there are lots of places with no FM stations.  Eastern Oregon, Nevada as mentioned already, coastal Washington State west of the Olympic Mountains from Seattle and Tacoma.

Last fall, I took a trip to western Nebraska, and at certain points, my Camry could only pick up 1 FM and 1 AM station each. They were both public radio of some sort, I believe.
As I remember, this was roughly midway between Thedford and Alliance on NE-2. That wins for me (people expect Nebraska to be desolate, but I was still blown away how empty this swath of the state was.)

On a trip I took out to west Texas a few months ago, I stopped for the night in Junction (I-10 at US 83/377). On my little Grundig G8 Portable (noted as a strong FM receiver), the scan function only picked up 2 or 3 stations, though I seem to recall Radio Locator showing up a few more. I found no others scanning manually, and I can't remember any place having less (carrying that radio around for a while).

We're not counting in tunnels are we?

On my 2017 trip to Big Bend National Park, we somehow picked up a San Angelo station on the car radio as we were leaving the park, but it wasn't very clear.
