My 2 year old Ameri-King AK451 ELT is broken......continuously alarms and doesn't shut off. The Search and Rescue people aren't happy! When I called Ameri-King I was informed they lost their FAA certification and can no longer either sell nor repair their units. So, I'm in the market for a new one. I'm looking for suggestions for a replacement. Nothing fancy....just 306 and 121.5 Mhz. Y'all's suggestions would be very welcome. Thank you.
