Interested in a meter for mW/cm2 measurements in the Amateur Radio 80M through 23cm bands. Is there a GQ model that will do this?

Hi WA6EJO, are you talking about 80MHz bands? It is covered in general RF .01-10GHz and also is included in Spectrum 76-108MHz.

No, 80 Meter band: 3.8 to 4.0 MHz. Plus the 40M band: 7.0 to 7.3 MHz, the 20M band 14 MHz to 14.35 MHz, the 10 Meter band: 28-29.7 MHz, the 2M band: 144 to 148 MHz, the 1.25M band: 222 to 225 MHz, the 70cm band: 420-450 MHz, the 33cm band: 902-928 MHz, and the 23cm band: 1240-1300 MHz. Those are some of the Amateur Radio Service (Ham) bands. So is there a GQ instrument that can make mW/cm2 measurements at those frequencies? There is a need for that now due to new FCC regulations.

The EMF supports the spectrum from these frequency bands:
2.4 - 2.5 GHz
779 - 928 MHz
387 - 464 MHz
300 - 348 MHz
76 - 108 MHz
65 - 76 MHz
50 - 65 MHz

The general RF/RF browser from .01-10Ghz can detect those frequencies but is not calibrated along those. It is better to use the RF Spectrum to measure specific frequency.
