What kind of modulation do they use?

[@AngelaMorley]

Thanks for this description, I'm just getting into satellite radio, and I was trying to piece together the history of this.

[@mungodarkmatter]

I am glad you found it useful. Their is some information on the SiriusXM Web site, but it is kind of vague and hard to find from what I recall.

dat intro

The SiriusXM Radio's use XM Infrastructure, The only Dual that picks up Both Feq. is called Mirge, it is the only radio i am aware of that can pick up satellites from either. But you would have to which between using XM Satilites and Sirius' satilites, cant use either at the same time. Until SiriusXM Launches new Satellites that can broadcast both sigals but can't use both bands at the same time, all recievers before the merger and now. this "SiriusXM" Branded Radios use XM Feq. they are technically XM Radio (I guess XM's Technology is better than Sirius is?)

[@MatthewKeys]

Nick's correct. I'm not sure what Mungo's talking about. The SiriusXM-branded radios use XM's satellites, not "both." And only the Mirge - which they don't sell anymore - was capable of picking up both satellites and decoding both audio encode formats.

They are actually a multi billion dollar company worth >24B dollars and have over 25 million subscribers. Hardly "going under" if you look at there annual reports reporting record revenues every year since 2009.

My 2011 Honda Pilot has XM but the channels I listen to say SiriusXM the same thing I hear on the app and also Alexa at the house so whatever signal you pick whether XM or only sirius I guess they're broadcasting the same music for the rest of us we hear it for them two different signal same music playing I guess

2019 Toyota still has XM only and a bunch of missing content because of it.

Xm copied Sirius fcc application, and then the fcc split Sirius original frequency. Only natural they got it back.
