Since I bought a new Yaesu FTM-6000R to succeed my Retevis RA25, I figured I would use my also new Surecom SW-102 to do some power comparisons. It was either that or do actual work, which I try to avoid.
I tested both into a 50 watt dummy load, and thus ignored the SWR. I tested based on the upper and lower frequency limits of some common services and also on the midpoints (which for GMRS and MURS really don't exist). Also, FM Narrow and FM both radiated the same power, so I just used FM. Note: This is an academic exercise, and I know that if I had an antenna connected that I would be violating a few rules, so no need to point that out.
