This is a very late correction on alanh's behalf for post #6 of this thread. It is prompted by recent discussion in another thread: Proposed New Digital Translators For Sydney.

Why did you post? It is only receivers which comply with the AS which will do this. There are many others which won't.
Perhaps alanh it was to help people avoid jumping to wrong conclusions about LCN allocations over 349. Or what would be more serious, misleading others by presenting an incorrect assumption as fact. Or what would be more serious again, presenting the incorrect assumption when at the same time taking on a position of presumed authority. There could also be present an aggravating factor of failing to consider and accept earlier correct advice when given.
As an apparent example of a combination of all of the above, namely, ignoring correct advice, making a false assumption, and presenting the false assumption as fact, with apparent authority, I refer you alanh for your consideration to the third in the following selection of four posts, all on the same subject matter, from threads in which you were involved:

The Unit is in fact issuing the correct LCN for duplicated services: from OP41:
If a receiver finds two or more services with the same LCN, then the receiver will allocate the subsequently found services to the next available unallocated number in the range 350 - 399.

If competing duplicate services (i.e. those that have the same LCN
allocated) are received from different transmitters, then a receiver that
complies with the Australian DVB-T receiver standard, AS 4933, will
place the service with the highest received quality in the correct LCN
position and the other(s) made available to the user, for example
stored at the next available unallocated number in the range 350 - 399,
unless it is intentionally duplicated by the broadcaster as indicated by
its presence in the frequency list descriptor of the NIT (see section
3.2.2), in which case it can be safely discarded.
After this allocation, in order to account for user regional viewing
preference, the choice of service competing for a common service
positioning should be user-selectable.
Table 2 provides a logical set of coverage overlap scenarios and
recommended receiver behaviour in accordance with 3.2 and 3.3

When the digital receiver cannot decode the Logical Channel Number sent by the TV transmitter it will allocate one from 350 upward.
alanh, on 06 November 2010 - 11:28 PM, said:
NOTE: LCNs of 350 -399 are reserved for when a receiver picks up more than one LCN from more than one transmitter. The subsequent LCNs are allocated to this number range.
The first post provided a correct indication in late 2004. Further refinement was provided in the second post, early in 2006. Yet a contrary, and clearly misleading, answer was promulgated by you (as self-appointed coordinator of "Get the Best Reception" threads) in early 2007. The post I have highlighted in red appeared, and still to this day appears, as post #6, early in this thread.
