Got this in my inbox this morning.
Improvements to the signal strength meter on the Point Dish screen will be available for 322 receiver models beginning 6/5/07 through a software upgrade. All transponder readings have been recalibrated for consistency so that loss of video will occur around 10 points. Please refer to the attached TIB and/or completed training from the week of 5/28/07 for further information on this subject. Future software upgrades to other receivers that change the signal meter will be announced in the future.
