How to test proper functioning of 406 MHz with 118 - 136 MHz radios?

The 406 ELT's still transmit on 121.5 as well. *So the FCC wants to
get rid of 121.5 ONLY units.

And the self-test on the modern digital 406 MHz PLBs is relatively
sophisticated compared to older analog 121.5 Mhz units. You can also
listen to the 121.5 Mhz homing beacon part as Tom mentioned to make
sure that is working. But since they have a unique ID and often
tranmsit a quick GPS fix expect a visit from CAP or others if you
screw up the allowed testing.
