Also a (slightly better) Peter Putnam review at HDTVExpert

Slightly better? Basement reception of stations over 20 miles away, with
indoor antenna, doesn't quite cut it, then? Or antenna aimed 90 degrees away
from the station? Doubting Thomas!
The LG receiver he's comparing it to, in my book, is 3rd gen, not 4th gen.
4th gen is the Linx, which was a newer chip.
The other review you posted, in the fringe area, isn't all that surprising.
All these receivers are probably quite good at just weak signal and gaussian
fading. Assuming that's what he meant by fringe area.
I was surprised by Putman's mention of 20 to 25 dBm (sic) of carrier/noise,
though. Unless the Digital Stream's C/N meter is way off, I'm getting a very
reliable 15 dB C/N, or just slightly more than that, as threshold C/N margin
requirement. With the indoor antenna, the C/N margin might be slightly
higher in some cases, but not much beyond 16 dB and change. But possibly,
he's looking at a very different echo profile.
Bottom line, though, is the basement reception at 20+ miles, of multiple
stations, and at 3.3 b/s/Hz.
