Spurious Emissions Test of the Radioddity GS-77s

This is the results of a Spurious Emissions Test of the Radioddity GS-77s.

*PASS

Within the 2 meter band, you can see that the radio does pass the FCC Standards for Part 97.307(e) The minimum needed is -49dBm and the Radioddity GS-77s under test was at -63 dBm.

 

 

The power output of the Radioddity GS-77s in the 2-meter band is 2 Watts on high power.

Overall the unit under test did pass the FCC Standards for Part 97.307(e). However, I will note that the unit does not have as tight of filtering that a name brand radios have. I will also note that the unit under shows to be slightly off frequency on both 2 meters and 70 centimeters. 2 meters was slightly better than 70 centimeters.

 

 

Test Engineer was Donald Ohse W5DRO.
Test took place in a temperature controlled lab 21.7 degrees Celsius.
Equipment used for the test are as follows: Rohde & Schwarz FSH13 Spectrum Analyzer 9 kHz – 13.6 GHz
Bird Watt Meter Model: 43
Bird Sample Model: 4275
Bird Coaxial Resistor Model: 8135
Wireman RG 8X 2 feet in length test cables.

Within the 70 centimeter band, you can see that the radio does pass the FCC Standards for Part 97.307(e) The minimum needed is -50 dBm and the Radioddity GS-77s under test was at -68 dBm.

 

Radio was programmed to transmit on 447.550 MHz. The Rohde & Schwarz FSH13 showed the peak to be at 447.589 MHz.
Radio was programmed to transmit on 147.550 MHz. The Rohde & Schwarz FSH13 showed the peak to be at 147.561 MHz.
The power output of the Radioddity GS-77s in the 70 centimeters band is 3 Watts on high power.
