fm radio

[dummy]

can i delay my fm radio 7 seconds

Yes, you will need to hold in 'memory' 7 seconds of information.
In broadcast we used magnetic tape.
There are probably solid state ways now.

Another option...

Maybe saying "now", counting up to 7 and then pushing "on"?

That is a delay too...

Placing your radio 2100000K meters away will also work.

I'll assume that you mean to delay an audio signal before transmitting such as is done in commercial broadcasting.

Take a look at the digital delay effects pedals used by musicians. That may put you on the right track.
