OK, this is the first problem I have encountered: I am seeing signal strength differences of 20 points between tuners on one HR20-700. This receiver is the most remote, about 70 feet of cable from 4-way splitter near the power injector. On all sats the signal strength is consistently lower on tuner 2 by 18-20 points. Closer H20 and HR20-100 have strengths pretty close to what they showed before setting up the SWM8 and show same readings on both tuners. I have done several RBRs on the remote unit and also unplugged the PI, but this has not changed anything. I don't know what the SWM readings mean, but they do show the same readings on tuner 1 and 2 (and are only a point or two below SWM readings on the closer receivers. The signal variances only show up on the individual satellites on the remote receiver. If this is showing a real reduction, 20 points is going to put me closer to rain fade on this unit... but maybe it isn't real. Any thoughts on this?
