Two stations at Sutro Tower will be switching antennas with each other when the digital transition is completed early Saturday morning. The combiners for the temporary digital antennas now being used do not work with adjacent channels, so the relocation of two of the channels is required. KBCW and KTVU will be swapping positions. The panels on the temporary digital antenna on Sutro are broadband, and do not require retuning. Only the inputs have to be changed.
To follow this visually, check the top Sutro diagram at:http://www.larrykenney.com/sutrotwr.html
The top panel now has KBCW 45 and KRON 57. After the switch it will have KTVU 44 and KRON 38. The third panel down now has KCNS 39, KCSM 43 and KTVU 56. After the change it will have KCNS 39, KCSM 43 and KBCW 45.
If the antenna swap wasn't made there would have been 39-43-44 on the third panel.
The new auxiliary digital antennas that have been installed and the new permanent antennas to be installed atop the towers have already taken this into consideration. Note Sutro diagram 2.
Remember, you will have to rescan to get KTVU, KRON and KGO after they change channels early Saturday morning. KGO should be on the air just minutes after the analog signal goes off, but KTVU, KRON and KBCW will be off the air while they change the antenna configuration and connect up the new transmitters. You will probably end up rescanning several times if you try to watch the change over in the early morning hours.
It's going to be interesting to see how everyone receives these channels after the move, as well as KTNC 14 on Mt. Diablo, KVIE 9, KXTV 10, KTFK 26 and KTXL 40 from Sacramento and KSBW 8 from Salinas. Friday and Saturday are going to be fun for us TV freaks who follow everything closely. Let's see your reports here!
