Squawk 7600 for one minute, then switch to 7700 for the remainder of the
flight. Fly the route as NORDO to your clearance limit.


That might work if the weather was bad where you were at the time of the
"radio failure" and all the way to your destination. If the failure
occurred in VFR conditions, or if VFR conditions were encountered after the
failure, you'd have to continue the flight under VFR and land as soon as
practicable.

What if the weather was IMC and others tried that dodge as well? What if
some of those other flights conflicted with yours? ATC can't provide
separation, you're all NORDO.

Squawking 7700 hasn't been part of the NORDO procedure for some years now,
by the way.
