After installing a SWM-8 module, I have a couple of issues. I have 3 IRD's connected to the switch - (2) HR20-700 & H21-200. When I have only one IRD connected (HR20-700), I receive signal strengths' on all nine SWM (transponders) channels. When I add a second IRD, I lose one SWM channel (transponder) signal strength on both IRD's. And when I add the third IRD, I lose another SWM (transponder) channel signal strength. So with three IRD's connected, I have signals on seven SWM (transponders) channels. Is this normal or is the SWM-8 module defective? It also appears that the SWM switch remains in the memory as the satellite setup in the HR20-700. When I removed the switch and reinstalled my system as pre-SWM, I was unable to acquire the satellite signal during reboot after a menu and hard reset. What procedure should I use to reinstall my system without the SWM-8 module?
