I have an old HR20-700 that I turned the access card back into D from an old deactivated account. Would it work on a new SWM SL3 dish that I now have hooked to a HR24-500. Is it very hard to get a new access card. i believe that the HR20-700 was one of the first ones that could work on a SWIM multiswitch. However, on the old account it was hooked up to a 4 x 8 multiswitch that had 4 cables in and 2 cables out to 3HD DVR's and 1 SD DVR.
