If it helps at all with these new Cleveland feeds attached below is my latest ZOB High Altitude chart for reference. (must be logged on to see them). All frequencies have been confirmed from recent monitoring.
I'm still trying to verify how Sector 02 and Sector 07 work. Sector 02, 128.62, is a low sector that primarily works DTW departures but will clear traffic to final their cruising altitude without handing them off to 127.67, which leads to to believe that these sectors are usually combined, or they do it with an LOA procedure ? Can anyone confirm if the same controller is usually working 128.62 and 127.67 ?
Other notes:
Sector 58 - 121.07 is an ultra high sector FL380 and above. I've never heard this sector work traffic but whenever I've checked the controller on 119.72 has been simulcasting on 121.07. Good to know if any of the new feed's can pick the ground side of 121.07
Cleveland uses frequency cross-coupling (noted with "xc" on the chart) on many if not all (?) their paired frequencies/sectors as required.
Sector 45 and 46 usually seem to be combined, with 135.375 used for area coverage in the west part of the area, controller simulcasting on both frequencies (noted with "sc" on the chart).
Any additional info or corrections always appreciated.
