Re: DTV is nice when it workls
said by cdru  : I thought I remember seeing somewhere that once the analog stations are shut down, the digital transmitters could power up to full strength. It is a mixed bag. During the simulcast period TV spectrum is pretty congested since each station is transmitting on two channels, one analog one digital. Some but by no means all stations are transmitting at lower power.
1) Pre transition many stations are already transmitting at full power with final antenna height and design.
2) Due to interference concerns or use of temporary equipment some stations are transmitting at lower then authorized power or using less then optimum temporary antenna. Post transition reception for these stations will get better.
3) Some stations will move DTV from temporary UHF channel to VHF. That should help coverage as VHF is less affected by obstructions like trees.
4) Once the dust settles some stations may submit modification requests to increase coverage area.
