There is no hopping with DSM2 which a great many users are still flying/using
That's true but it's still a very secure system because there are many frequencies available (maybe 100?) and the Tx picks two free ones when you turn it on. The chances of some source of interference randomly blocking those two frequencies at the same time is infinitesimally small in most scenarios.
