That's true. But all the more reason for combining the low-power receiver
supply with the usually larger transmitter supply. But in general, for most
receiver supplies, there is also a separate transmitter supply designed to
operate off of the same source (voltage and frequency). The only exceptions
seem to be 6 VDC, 24 VDC and gasoline. That I've managed to ID, anyway.
