Hi, I have a Yaesu/Vertex VX-150 & VX-6R. Was looking at the manuals the
other day and noticed the different emission types. Essentially the 150
uses Phase modulation (G3E) and the 6R uses FM (F3E).

Will there be any appreciable difference in the performance of these radios
because of this?

I have noticed that, using an interchangeable antenna, the 6R has a greater
range than the 150, even though they're both supposedly putting out 5 watts.
Could the different emission types be the cause of this?

When you say Range what exactly are you talking about?
Range is a combination of transmit power, receiver sensitivity and
propagation path.

Do you know what power the radios are putting out
Did you measure there output?
Do you know the receiver Sensitivity for these particular radios?

Published specs are for comparison only, actual production radios will
differ from published specs by significant amounts.
