    Answer: A

    Good question Trip. I leant about frequency-hopping spread spectrum today. :D

    Today i learnt about FHSS and DHSS, very nice!

    I go with A too, a dwell time of 400 ms.

    Fingers crossed...!

    :)

    Time's up, gang. Actually, the correct answer is B. Dwell time is the amount of time an FHSS radio is transmitting on a particular frequency. To hop from one frequency to the next, it needs to stop transmitting for a short period of time called hop time. I used this QOTD on another forum and dwell time was also the runaway favorite. I double checked my terms and hop time is the correct answer.
    That should be "FHSS and DSSS". :wink:

    Another question tomorrow.
