I stand corrected. I meant to say I could not get decent convergence over every part of the round screen, although that may well have been because I was trying to converge the tube by eye instead of using a generator.

Quote:
A proportionate increase in power of all VHF stations would solve the noise problem without causing added interference between stations, but this is impractical economically due to the number of transmitters that would have to be replaced and commissioned simultaneously. It also involves international treaties regarding interference levels across the Canadian and Mexican borders. Hopefully this will be taken into better account with ATSC 3.0 broadcasting. It is a tough nut to crack because stations cannot arbitrarily increase power individually without considering interference to other stations that do not change at the same time. |
