Icom IC-V86
 Compliance Test

Compliance testing to ascertain if this radio meets ITU guidelines for spurious emissions.

Icom IC-V86 Final Grade: PASS

The Icom IC-V86 amateur radio sample tested in our evaluation exhibited outstanding performance on its dedicated 2m band. Our measurements detected no spurious emissions exceeding the permissible limits set by ITU guidelines. Notably, all spurious emissions were suppressed by at least 61 dB relative to the power at the antenna, making this one of the cleanest radios we have tested to date.

It is important to note that this was a single-sample test and it is possible other samples could vary in performance.

Power Output Testing

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.

2M

146.520 Mhz

6.4 watts

Using the ITU formula of 43+10log(P) dB, spurious emissions for a signal of 6.4 watts must be at least 51.1 dB below the power supplied to the antenna transmission line.  6.4 watts is approximately 38.1 dBm, which means no spurious signal may exceed -13 dBm, or approximately 50 microwatts.

Spurious Emissions Testing

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. 

VHF 2m Band Test Results: PASS

Raw Data 2m

All numbers have been rounded

Power at Antenna: 38.1 dBm (6.4 watts)

Fundamental (f0): 36.8 dBm (4.8 watts)


The Icom IC-V86 sample that we tested displayed no significant spurious emissions above the 2m band fundamental in our testing.  All spurious emissions were at least 61 dB down from the power at the antenna, which is not just fully compliant with ITU guidelines, it is among the cleanest radios we have ever tested.


Comments

No surprises here.  Many thanks to Manvir VA7BKI from the Surrey Amateur Radio Communications Society for the use of his radio for testing.
