Today I posted a update to the DBS3500 Q series receivers.
"Q" operating software - March 4, 2010
Upgrade to the satellite/transponder database.
This upgrade is only to add a more recent satellite/transponder list inside your receiver. If you have your own list there is no need to install this upgrade. This upgrade will erase any saved information in your receiver.
