radiospmr@kosmasgr84 Thereis some confusion here, earlier people used to refer to the transmitting power of the radio as the current drawn by the final stage (or the whole radio) during transmission, as radio testing equipment (even RF Power Meters) were very expensive, and they used Ammeter to measure the current drawn by the final amplification stage (or the whole transmitter). Yeah the radio consumes over 1.5 Amperes 8.4 volts (battery fully charged), the battery voltage also drops slightly during transmission

radiospmr Yes these modules can work on 27 MHz and other UHF (FRS, PMR, GMRS) CB frequencies. but be aware of lower input and output power level ratings of the module and device used in these, which may be limited to just few watts (1-4 watts). they can work to amplify low level signals to approx. 1-3 watts, which is actually góod.

radiospmr same issue common with all instruments trying to measure voltage, current and power measurements. you can offset this by trying to measure voltage and current at the output port sharing the same ground location. location of probe points can becrucial in determining accuracy. therefore lab grade instrumentation for precise measurement is expensive and out of reach of most. so you must accept slight inaccuracies in affordable instruments.
