My understanding is that Spectrum Tuning Adapters were mated to our Roamios just like the Cablecards are. In fact, I seem to remember giving out TA serial numbers to Spectrum reps in the past. Now, when reactivating an old Roamio I've been told by Spectrum that all TAs are interchangeable, that they don't keep track of what TA is on what box. Is this something new or am I imagining things?
