Sirius Pulls Radios from Online Store
Tuesday, June 27, 2006 at 8:45 AM
A couple days ago a loyal reader noticed that all Sirius plug-and-play units were being listed as "out of stock" on Sirius' online store. Not sure if this was a glitch or a restocking issue, I held back from jumping to any conclusions. Yesterday, GSI had gotten word that Sirius units were actually pulled because the radios are getting a retool over FCC transmitter issues. Following a possible FCC inquiry, Sirius will most likely be shipping receivers with weaker FM transmitters in the near future.
The timing behind this is impecible.
Sirius appears to have pulled the units almost immediately after the NAB's FM modulator report was submitted to the FCC. In the NAB report (which you can view here - PDF), only two satellite radios were included in the tests - the Sirius S50 and the Sirius Sportster Replay. Looks like the NAB is done with XM and has now set their sites on Sirius.
In the report, the Sirius S50 and Sportster Replay were found to have two "violations" - one being that the FM antenna did not comply with FCC antenna requirements and the second being that they exceeded transmission levels.
Here's the breakdown (because the report is a snooze-fest):
- The FCC limit for FM transmitter emissions is something like 48dBuV/m.
- The Sirius S50 came in at an average of 74.7dBuV/m.
- The Sirius Sportster 4 came in at an average of 74.8dBuV/m.
(Interestingly enough, the NAB results contradict reports that the Sportster 4 has a weak FM transmitter.)
UPDATE: The NAB tested the previous generation Sportster Replay SPTK2, not the Sportster 4 as previously stated.
Even with a vehicle's insultating properties, the Sirius S50 still came in at an average of 56.7dBuV/m.
So what about the antennas? Apparently the supplied antenna is only a #20 guage wire (which is a no-no for some reason). Also the Sirius antenna connectors consist of a standard 2.5mm audio connector, and that violates the FCC requirement that the connector be a unique connector. The whole intent of this requirement is to prevent the use of an antenna that can be used to boost the signal beyond required emission levels.
