Hi David,

Help me out with the 100,000 single point failures. Are you referring to the
complexity of digital gates etc., in the DSP.

Isn't P3E going with a digital IF or are they using an analog backup or vice
versa? That's the SDX thingy isn't it?

Hello Bruce / Dom.

I agree, the UV on Eagle will be apparently analog (ue) to the casual  user.

But be aware Bruce that it's not "primarily" a software driven  transponder.

It is in fact TOTALLY software driven.  There is no linear IF, just  DSP in
the core.  Or from another viewpoint  100,000 single point  failures just
waiting to happen.
