I'm using a Motorola DSR 4500X - this model is capable of receiving DC2 un-encrypted channels ZK and FP mode as well as tuning in analog channels -CSPAN. It cost about $75 at the time. I suppose if you're looking for a dish mover, then an old receiver would be better. If getting CSPAN + a few other SD DC2 channels is better - then consider a DSR 4500x
I have a Motorola DSR 4410 here that I bought really cheap a while back on eBay to try out the DC2 stuff that iBoston posted about. I wonder if it has the capability of tuning the analog CSPAN like your 4500X?
EDIT: Looks like maybe. Specifications state: 'AN ADVANCED DIGITAL SATELLITE RECEIVER FOR ANALOG SERVICE CONVERSION AND BASIC CABLE OPERATIONS'
Wow, its been a while since I first posted this and I'm just getting around giving this a try since the 'current events' have had me otherwise distracted. Did a little research and found this document. Even though these are specs for the 125W move it appears the 4410 does analog so hoping it will work. I need to check the firmware verson in my unit. If good I may try this on Sunday. Wish me luck!Maybe means TRY IT!
It also could mean using the ASI port (digital) vs composite video (analog) to be used to switch cable headends from analog to digital.Good luck!
