Icom IC-208H power output

[KC2VOB]

Hi All,

My IC-208H puts out roughly 35w on 70cm while it's advertised as 50w on this band. Is this common or a flaw?

The meter you are using is known to be correct at UHF frequencise? Also, is the VSWR in the range of 1.5:1.
High VSWR will cause a decrease in RF as a method of protection. And some (some!) do not read correctly at UHF. Learned that one the hard way..

And let's not forget the input voltage too. This should be measured right at the radio, not at the battery! The reason is, the power cable which comes with the radio is barely adequate voltage drop wise.

Further, it has been noted in reviews of the radio that the power out is a few percent lower than advertised.

In any case, the only way to be sure, is transmit into a dummy load, with a known-accurate wattmeter. Even then, 5% is as close as you're liable to get.

the good side of this is you can probably not hear the difference between 35 and 50 watts through a repeater.

Even the "dummy loads" matter around this frequency!  Stray capacitance and inductance becomes a problem.  So does coax cable losses... and connectors to some extent.
So make sure the proper DC power is getting to the radio, and the test system is designed for this frequency range also, as it is easy to get a "false" reading on 70 cm!
