Hello,
Mode A and C transponders only transmits when they are interrogated.

Concerning anticol devices; i fly with a Proxalert R5 and this guy is
impressive. It's much more useful than the Surecheck devices. It's the
ONLY device to display SIMULTANEOUSLY up to three threats info
including squawk code

Transponder: transmits as a response? As far as I know, they
only transmit when interrogated (at least the OLD ones did).
