The RFX-150
and the SX-175 both contain the same amplifiers inside. The only difference
is the size of the heatsink (fins) on each one of them. I don't know why
they decided to call one the 175 and the other a 150. Both have the same
electronics inside.
Think of the RFX-150 as light duty and the SX-
175 as heavy duty as far as talk time before overheating. If you talk a lot
and use SSB a lot, then the SX-175 is best. If you listen a lot and use
mostly AM, then the RFX-150 will do fine.
