Increasing the ability listeners will find it. Many still do not grasp how to find HD subchannels so in theory this doubles the chance at discovery.That said, it’s still a mystery to me why WSUN is on two HD2 signals, same tower, coverage range, etc; I could understand if they were on two different towers; right now, I’m in an area between Tampa and Orlando and just checked and WSUN- is coming in on both 94.9 HD2 as well as 101.5 HD2; seems redundant.
There was a story going around a couple years ago that iHeartMedia CEO Bob Pittman got into an Uber and inquired as to why the driver was listening to WHTZ-HD2. Driver responded that he couldn't figure out how to switch it back to the primary Z100. Pittmann ordered all HD subchannels turned off the next day, but had to roll back on that when told that there were many financial and contractual reasons behind many of them being on, but WHTZ-HD2 was removed that day.
