There is a massive solar flare from the sun on the way to earth.
Do a careful range check. Especially if you use 72MHZ
Google solar flare for more info.

When I was active in amateur radio, we used to love solar flares and the like. During one period, I sat it my driveway in San Diego, on my mobile rig, and listened to the "skip" work its way all the way from Hawaii, to the West Coast to the East Coast, and talked to New York during the period. Absolutley unheard of during normal periods.

www.spaceweather.com has info and a movie of it leaving the sun.

It looks like to me that 2.4 is s just a much at risk as 72. Second paragraph states 'all wavelengths from radio to Gamma rays.' That includes 2.4

But you just have make it look like only 72 is affected.

The lower the frequency the greater the atmospheric penetration of the energy.
If this were not true we would all be fried by the gamma rays in this burst.
72mhz is much lower in frequency than 2.4ghz.
Satellites use 3.0 ghz extensively, and are at risk, but they operate above the atmosphere and don't have its protection.

2.4 Radios communicate via coded signals, 72Mhz does not.

Thats not true, PCM uses proprietary encoding and checksums.

Don't have a Winnebago, but we did just get a Tioga, and the desert is not far from here:-)))))))))))))))

It wont help. You need a carbon fiber cocoon.

wonder if a left-over "cone of silence" from the old Get Smart TV show days would help any...

So what....2.4 is at risk too. Not just 72.

2.4 GHZ is not nearly as much at risk as 72mhz.
In the early 70's many Logictrol sets had their first two transistors burned out by a jolt from solar flares. The receiver had to be modified to prevent that.
