I'd really like to see IBOC go to where the rich man went (in the story of him and Lazarus). >:(
If IBOC stays, though, I was thinking. Maybe the stations that suffer from its interference could have a way of combatting it without further authorization from the FCC? For example, allow the station, without a CP or STA, to increase its transmitter power - so that, the S/N ratio of unmodulated carrier to peak noise/hash in the deepest pattern null and/or place where interference is worst, is the same as what a fully-modulated signal would be in the strongest lobe at the same distance over the noise level in a theoretical giant screen room. Also I was thinking of a way to get the FCC's attention, although I'm sure no one will do it. :p Find out what is the most popular AM station for the commissioners, agents & employees to listen to. Then, build a ring of adjacent stations around Washington. These would be 50kW, have 12+ tower patterns entirely directed at the main FCC office, and would just barely comply with the 1st-adjacent 0.25 vs 0.5 mV/m groundwave protection of the "desired" station. They'd also, if possible, negotiate accepted mutual interference among themselves, similar to what a graveyard channel has at night, or what a class D has from a 50kW class B 4-500 miles away with its entire 8-tower pattern blasting toward the D. The antennas would be configured for almost no groundwave (you couldn't detect the carrier in QRSS CW/PSK31 with a beverage antenna and Perseus standing on the end of the ground radials, assuming 50kW TPO, 540kHz and saltwater path) and lots of skywave (overloading consumer radios at 500 miles to the point where you have severe distortion on-frequency, making the station unlistenable). I wonder what that IBOC hash would be like at the FCC offices? :o ------------------------------ On Sun, Sep 1, 2013 8:30 PM PDT Barry McLarnon wrote: >On 09/01/2013 03:00 PM, Craig Healy wrote: >> Now if only WBZ-1030 in Boston, MA drops IBOC, there will be some happier >> adjacent stations. 1020 Pittsburg, PA and 1040 in upstate NY. >Don't hold your breath for that one.
