[Elecraft] [K3] K3 beta firmware revision 3.14 now

[Mike Scott]

I think higher audio levels may be needed to test the speaker protection
function.

I inadvertently tested speaker protection. I was using the XG2 to do some K3
audio tests. I had the XG2 off and I turned the RF gain to full, AGC off and
audio up to where I could hear "Band" noise. Turning the audio up that high
was a mistake on my part. I then hit the K3 with an S9 signal. I woke up the
neighbors and triggered speaker protection as I was really over driving the
audio at that point. 

I thought I had blown an audio stage but remembered the protection feature
that worked on over current. So, sure enough the speaker setting had been
changed to Speakers = 1. 

At least I didn't put 100 watts into the XG2 :)

Anybody else tested this?
I can't get speaker protection to work.
Or does it only work with higher AF levels?
