on the sirius recvr, I have what almost sounds like crosstalk or adjacent channel bleedover. It usually is heard on quiet programs or between songs but you can also hear it during music. The added tweeters have made it more noticeable because of the high frequency response.sounds like tape hiss the goes in and out adding an underwater "wavey" sound

 

Did Sirius come with the JK, or is this a separate receiver?

 

no this is the Jeep 6 disc head unit with sirius built in

 

I don't have the 6-disc with built-in Sirius, but I've had other head units with Sirius directly wired-in... you shouldn't hear cross-static at all.

I'd see what the dealer can say about it!

 

I've had Sirius for a while now, but when I first got it, I remember being pretty surprised at all the compression artifacts that I was hearing, especially on the talk channels.

If you've never heard it, a compression artifact is a little difficult to describe, but it could match what you say you're hearing. Basically, if you've ever heard an MP3 that was sampled at a really low bitrate, you will notice a sort of warbling in the cymbals, or when a singer makes an "s" sound, those are compression artifacts. They happen when too much information is discarded during compression.

Sirius needs to fit about 150 channels in about 4.5 Mbps of downstream bandwidth, which does not add up to much per channel. Consider that a song you buy from iTunes is sampled at 192kbps -- you'd only get about 20 total channels if you left it at that rate. They actually use some other tricks to save bandwidth, but they're pretty tight, and the less bandwidth you devote to a channel, the more artifacts you'll hear.

Okay, sorry if that was a really long explanation for no reason, but if that's what you're hearing, don't bother "adjusting your set" -- it's not going away any time soon

 

probably what im hearing ,but may visit dealer anyway ,gf's sirius didnt have as muchas i do and my xm didnt have it at all.... but good explanation ..Thanks

 

anybody else noticing this? seems to happen more when the interior is warm...how bout you guys with aftermarket stereos w/ sirius? It is very annoying and my fm actually sounds better...I am afraid my add-on tweeters just makes it worse by actually playing those frequencies so they can be heard.

 

I had the same thing this past weekend when listening to the NASCAR race, at first I thought it was the "in car radio" discusssion between the the crew chief and driver.....but while difficult to hear, it almost sounded like it was police band radio , or someone else who was carrying on conversations .....and they were not about NASCAR.

This want the first time I have noticed it.

 

All I can say is XM!
I have had both and XM gets way better reception.
