XM Radio Hits Some More Interference

XM RADIO HITS SOME MORE INTERFERENCE
[SOURCE: Washington Post, AUTHOR: Kim Hart]
XM Satellite Radio Holdings Inc. reported new difficulties this week, adding to its year of problems with regulators and with growth in subscribers and revenue. In documents filed Monday with the FCC, XM said 221 land antennas, which transmit satellite signals to local devices, were operating at power levels in excess of commission limits. The company also disclosed that 19 antennas were at sites not yet authorized by the FCC. The company has 800 working antennas. For example, some antennas have been transmitting signals at lower frequencies than the company originally submitted for the FCC's approval, and others are across the street from, or on a different floor of, a building than where the company originally reported. This could interfere with signals sent out by other broadcasters operating adjacent to those frequencies, said Paul Sinderbrand, a lawyer with the Wireless Communications Association International who represents companies with licenses to operate in the frequencies adjacent to the signals used by XM and Sirius.
