Gentlemen: A portion of the request is reproduced below. To: Scot Rogers, null From: Stan Lyles [email protected] FCC Application Processing Branch Re: FCC ID AJT-GS12RII-V1A Applicant: GE Transportation Systems Global Signaling LLC Correspondence Reference Number: 23068 731 Confirmation Number: EA363196 1.) ) Justification for your certification request of CFR Parts 22 and 74. How and where will the device be used under these Rule Parts. Please specify all rule parts for 22 and 74 used for this device in test report. For example RF Power Output, what rule 22 and 74 was used, Modulation Characteristics, what rule part 22 and 74 was used, Occupied Bandwidth, what rule 22 and 74 was used ect. 2.) Please resubmit a new Users Manual Exhibit 8. There was an error opening this document. The file is damage and could not be repaired 3.) .) Please note that the attenuation requirement for radiated spurious emissions is referenced to the desired signal yielding dBc. The attenuation specification is not XX uV/M, or derived from absolute value of the field strength. The dBc is determined from the substitution method such as described in the ANSI/TIA/EIA-603-A-2001 document. What is needed is a determination of the actual power levels necessary to reproduce these field strength levels. Those power levels (from a signal generator source and a dipole antenna replacing the EUT) are ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 Phone / Fax (913) 837-3214 then compared to the power output of the transmitter to determine dBc. That is the basis of the "substitution method". Please submit data / results obtained in this manner. RESPONSE: 1. The original transmitter (FCC ID AJTH12RT-V) was certified for operation in the part 22, 74, and 90 for operation. This equipment is a repackaging of the Kenwood transmitter, which is now the current model available. The paragraphs of interest would include 22.355, 22.359, 22.561, 22.565, 74.402, 74.461, 74.462, and 74.464, along with applicable paragraphs of part 90. This unit will be used mainly for operation under part 90 in the railroad industry, however there may be occasion requiring licensing under parts 22 and 74. 2. The user manual was uploaded to the web site for review. 3. Testing per TIA/EIA-603-A-2001 has been completed and added to the test report. Please use the 12R2ATstRpt.pdf file for the corrected information and submittal. Thank you for your help in resolving these issues. Please continue with the grant of certification process.

The modulation is generated by an MX829 Baseband Signal Processor chip (a PDF for the MX829 data sheet is included) with integrated filtering. The 12RII radio uses the MX829 to communicate at 2400 BAUD, half duplex, with one half cycle of 1200Hz for a ‘1’ and one cycle of 2400Hz for a ‘0’. The MSK data is continuous phase using standard deviation of +/- 3KHz for wide band operation and +/- 1.5KHz for narrow band operation.
