I can believe it easily -- more indication that NTSC viewing has NOT 
provided training in DTT reception.

In most of the receivers I've tested, there IS, indeed, some sort of 
indicator.  It has not proved useful at all here.  It can change when a 
truck goes by (three stories below), there is a huge delay between 
antenna movement and indication, and, in some cases, higher-numbered 
stations don't come in when lower-numbered ones do.

Having announced my delight with the 5th-generation LG-prototype in the 
summer of 2004 (at least 18 months after it was first publicly 
demonstrated), I clearly eagerly await those new boxes.  The boxes that 
have been tested here since then have not worked as well.  So far, the 
LG prototype remains the only one to function with a set-top antenna of 
any sort in any orientation.  Meanwhile, my set-top rabbit ears continue 
to work fine for NTSC reception.
