SMC's marketing a so called "High Power" 250MW "B" card (Micro Center),
what a crock !
Speck sheet reads like imported audiophile bull### and power rating claims
and confusion Pioneer was passing off in the 70's
Looks like a repackaged stock device to me......+ 2 mini RF couplings.
The box says "250 milliwatts"
HOWEVER that's 250 milliwatts ERP ***Effective Radiated Power*** with 2
external high gain
antennas. (also not disclosed clearly in the fineprint on the box)
Plus the cheap plastic stock antenna "wafer" constantly falls off !

I brought mine back after a 5 minute checkout and complained to Micro
Center.
I wonder if SMC is related to Audiovox's FRS division
