About the viability of VHF-HI...
WLS-DT in Chicago has been operating on 4.75 kw at night between 1:05 AM and 2:05 AM, and then probably later at night; see the last few pages of the Chicago OTA thread on how it is getting out. 60 miles away, low in a river valley with "sparklies" just before they turn off their analog 7 transmitter and turn on their digital, I can lock it without a problem. Their Chief Engineer commented to me and I got permission to post those comments as well. Check it out!
