    The 0.4 was the capacitive supply that really was idle; the 1.3 & 1.4 have superregenerative RF receivers which are never truly idle. The point was that capacitive supplies are not inherently wasteful.

    Tle last 5 devices all use transformer PSUs as they have serial ports and require isolation.
