Lesson learned.......
The satellite test
DOES NOT work with KANNAD ELT's. I paid $30 and ran a test on a Cessna Sovereign. The 406Test folks did not get it, but...... we "did" receive a call from whatever entity monitors aircraft/ship ELT's. They got it!!! And.... we got a slap on the wrist.
Another issue with this type of ELT is that is doesn't actually send a data burst until 50 seconds after activation. In the meantime, the 121.50 signal is blasting out for all to hear.
I think best practices with KANNAD ELT's is to use a handheld tester directly connected to the unit and a dummy load on the VHF output.
