I'll apologize in advance, George and others as I've told the story so many times I'm now suffering from destination memory on this topic.
I first had a Amer-King ELT because an ELT was
required equipment. Didn't have any problems with it (still have it on a shelf). Rumblings came along that 406's were going to be
"required", so thinking they were a better thing I went out in 2010 and got a Ameri-King 406 because the mount was identical to the old unit. Meanwhile, lots of bad press that A-K products failed to work properly. The beauty to me, is the 406 AmeriKing has a B.I.T. ( or Bite if you prefer) which works very well. My plane was laid up after I bent it in 2015, started to fly it in 2017. Before I flew it again I took my ELT out to the local shop to give it a full check out. Learned from the shop that my unit was working perfectly like many A-K's. That's not to say that A-K's won't fail but there we a pile of other ELTs types with issues on his bench, so there is a failure rate. That's why we test them and as I mentioned I thought the test was good but didn't realize how good the test was until I reinstalled my unit and did an install bite. Next day I get an email from the Regs that they had received the test signal but because it was 18 months since the last one from my ELT, they requested that I update my ELT registration info.

The one problem I do have with my ELT is the battery pack is due for replacement. The battery pack needs to be replaced every five years by regs but the battery pack is built to last at least 10 years (possibly, physically longer). My pack is now 7 years old works fine but I'd like to replace it. Now the spat between the F.A.A and A-K has finally been semi settled with an AD, to the detriment of 14000 users because the F.A.A. won't let Ameri-King sell replacement batteries.
Me? I'm looking for a non approved battery pack made by an Ameri-king supplier for my next annual.
Oh, now that the 406 mandate seems to have stalled now, I'm thinking of ADSB because it's going to be
"required".......Nah, couldn't happen to me ..again!!!
