Not in the Linx or LG designs. I said A/74 because the
Samsung receiver, which measured better than the previous
two, was claimed by the CRC to meet A/74. That's the
newest one of these new generation receivers, as far as I
know, and the echo tolerance and sensitivity measure quite
a bit better than the measurements achieved with the
early samples of the Linx and LG.

Like, 4 dB better in Brazil E C/N margin required (20 vs
24 dB C/N min margin), and about -85 dBm vs -76 dBm in
ultimate sensitivity.

Since Mark reported that this new Samsung receiver did
about the same as the other recent designs, but not as
well as the prototype LG 5th gen, I have to conclude that
A/74 must be at least adequate with respect to echo
tolerance.
