Hi Joerg,
Thank you, you have pointed this twice, now I understood.
The loop can be rewritten for clarity.
 while (i--)
      {

        // Select this channel
        radio.setChannel(i);

        // Listen for a little
        radio.startListening();
        delayMicroseconds(130+40); /* see manual ch6.4. */
        radio.stopListening();

        // Did we get a carrier?
        // if ( radio.testCarrier() ) ++values[i]; /* L01 device */
        if ( radio.testRPD() ) ++values[i]; /* L01+ device */
      }

But I am afraid I still see bleeding signal across three channels. 
I wonder, if at the transmitter node, I could use the continuous wave
for the carrier detect test, not sure what purpose is that wave.

Also transmitter/receiver nodes are very close to each other, in
reality they could be some 70-100meters apart, should I try to lower
the signal level, perhaps it incurs some noise of signal being too high?

Many thanks so far.
