Icom IC-92AD
Compliance Test
Compliance testing to ascertain if this radio meets ITU guidelines for spurious emissions.
Compliance testing to ascertain if this radio meets ITU guidelines for spurious emissions.
The Icom IC-92AD amateur radio sample we tested performed exceptionally well across both of its bands. We measured no spurious emissions exceeding the levels permitted by ITU guidelines.
It is important to note that this was a single-sample test and it is possible other samples could vary in performance.
Power output was measured using a Surecom SW-33 Plus into a dummy load. The radio was set to maximum power. The ITU guidelines for spurious emissions require measurements of "the power (W) supplied to the antenna transmission line". That requirement makes this separate power measurement necessary, as it is incorrect to measure relative to the fundamental (f0). All numbers have been rounded.
4.9 watts
4.9 watts
Spurious emissions were measured using a Tiny SA Ultra. The radio was set to maximum power and was connected to the TinySA through an attenuator. It is important to understand that the graphs below are using a decibel scale, not a linear scale. If a spurious emission spike appears to be almost as tall as the fundamental, that does not mean it is emitting almost as much power. Refer to the raw data shown.
Power at Antenna: 36.9 dBm (4.9 watts)
Fundamental (f0): 35.9 dBm (3.9 watts)
The Icom IC-92AD sample that we tested displayed no significant spurious emissions above the 2m band fundamental in our testing. All spurious emissions were at least 58 dB down from the power at the antenna, which is fully compliant with ITU guidelines.
Power at Antenna: 36.9 dBm (4.9 watts)
Fundamental (f0): 35.9 dBm (3.9 watts)
The Icom IC-92AD sample that we tested displayed no significant spurious emissions above the 70 cm band fundamental in our testing. All spurious emissions were at least 58 dB down from the power at the antenna, which is fully compliant with ITU guidelines.
No surprises here. Many thanks to Scott VE7KAT from the Surrey Amateur Radio Communications Society for the use of his radio for testing.
