The equipment is used in oil and natural gas exploration for a seismic data acquisition employing RF telemetry or cable. Sercel, Inc. designed and manufactured the radio equipment of type Accepted FCC ID: KQ9812, KQ9816, KQ9819, KQ9901, KQ9902, KQ9903 and KQQLRU under FCC rule part 90.259. In the international market there are many such system employed. These equipment falls under FCC rule parts 2, 15 and 90. FCC rule parts 90.203 (a), 90.209 (a) and 15.101 (b) for transmit portion and receiver portion. In addition FCC rule parts 15.3 (k) and 2.1057 (a). If you require other information please let me know. Thanks. Have a nice day.

Message Page 2 of 4 What FCC rule part governs this? *** Non—Public: For Internal Use Only *** -----Original Message————— From: Mike Xie [mailto: Michael.Xie@sercelus.com] Sent: Monday, July 12, 2004 3:56 PM To: Carl Huile Subject: RE: The Experimental License Hi, Carl, Recently we are developing a new Transceiver for system use. The transceiver performances are basically the same as existing transceivers. Only new transmitter employs a phase modulation scheme, QPSK. Existing transmitter uses a frequency modulation scheme, FSK. The data rate of new Transceiver is 256 kbps per channel. Its occupied bandwidth is 180 KHz per channel. The new transceiver has a 4— channel operating capability. So the occupied bandwidth of containing four— channel digital information will be 800 KHz (720 KHz at least). So we request to add a Emission Designator of 800KG7D. If you require more detail justification please let me know. Thanks.
