Here's a nother question for the new forum here; are there any real world distance test results for how far a handheld atsc-mph phone can receive mobile dtv signals from broadcast towers?

One thing about having XM / Sirius in my car is that I can receive pretty good reception as I'm driving around town or if I go on a trip, I can take my tuner with me and listen to the same stations as I was listening to in town. That won't be the case with atsc-mph...which is going to definitely be a pain having to constantly rescan while on the road to find new stations.

Doubtful right now, try finding anyone that's done a review or pre-release review on one of these atsc-mph tvs or phones. just no info out there.

I heard one person comment they were in Durham and hadn't needed to extend the antenna on the Mobile DTV receiver yet to receive WRAL-DT cleanly.

90 miles? WRAL is in Raleigh. It's not that far.

You're right, slight miscalc. there, looks like just over 20 miles.

Both TVFool and my best guess plotting on Google with distance measuring tool show 29 miles and change.

That is impressive even from a 600 meter tower.

(better than I can do on VHF [added because I am still discussed at NBC])

You are making assumptions to what is available as to what might be proposed.

There are no phones with ATSC or MPH to my knowledge.

But comparing XM/Sirius that is a satellite service that covers the united states to a terrestrial tower that covers a 60 or so mile radius answers your own question.

XM comes from a satellite. no matter where you are in the US you receive from the same satellite.

MPH is broadcast from towers as "hitch hiker" to the main stations home signal. So wondering if you get the same stations while you travel would be the same as wondering if you get the same TV stations when you travel.

In other words can you take your TV and rabbit ears to a city a few hundred miles away and pick up the same stations? of course not. same for MPH.

I know that comparing atsc-mph to XM/Sirius is kind of silly, but there are going to be plenty of travellers like me that are going to want something that works without having to constantly rescan for new channels every hour or so during a long trip. I know that I won't be able to receive the same NBC affiliate on the same channel in LA that I do when I go to San Diego, I guess my question is more in terms of what are the actual distances atsc-mph will travel, and I also wonder what the rescan rate of time will be for atsc-mph? If it's anything like ATSC, it'll be a PITA for sure.

Still we are comparing radio to TV. Though in technically MPH could be used for audio only.

So yes, I think you are right, that a national coverage via satellite over the road, wins hands down. You tune your favorite radio stations regardless of location. I can totally appreciate and like that idea personally. Wandering a little off topic but I always said that XM/Sirius was made for over the road people such as long haul truckers. It's perfect. I know a few and get the same answer from all of them that have XM/S systems in their trucks. First retuning for FM got tiresome 10 years ago, and most went to CD players then MP3 where they could program hours of music without touching the radio/player. Unlike what most car drivers don't realize till they wreck is distractions are very serious with disastrous consequences, so the less they touch the dial, the better. Then they say they still keep a few favorite CDs in the truck but mostly they just have 5 or so their favorite XM/S stations in memory and hardly ever touch the dial any more moving.

No idea what the rescan rate will be, but Trip knows someone in Durham NC from Raleigh NC 30 miles away. Now that station has 400 some meter tower running full bore. But still 30 miles handheld without him pulling out the external antenna is pretty good.

But for someone over the road, 30 miles is a long yawn.

So I bet the best system for over the road is XM/S combined with a CD players for audio. Then a DVD player for Video in motion.
