Looks like TVTechnology finally decided to write an article about all of the VHF reception problems we've been discussing here at the forum lately.
What is the solution to the VHF DTV reception problem?
Some VHF DTV stations have had significant problems with the DTV transition. Affected markets include Chicago, Philadelphia, and Washington D.C. While many of the news reports focused on ABC affiliates' difficulties in these markets, ABC wasn't the only network affected. NBC affiliate WHDH-TV in Boston had so many problems after moving to DTV Channel 7 that it applied for, and received, authority to move back to its original DTV Channel 42 until matters could be resolved. Fox affiliate WSVN, operating on Channel 7 in Miami, requested special temporary authority to increase power from its authorized 31 kW to 63 kW. CBS affiliate WJZ-TV Channel 13 in Baltimore, requested authority to increase power from 9.8 kW to 27.5 kW.
