4021 Stirrup Creek Drive Suite100 Durham, NC 27703 Tel 919.361.2479 800.849.4447 Fax 919.361.2948 800.849.2947 To whom it may Concern: This letter is to address an issue that has been raised relating to the process of licensing stations that use the DRTXM4. The licensing process is done by HIS to conform to all the provisions of 90.242. In particular, with respect to the specific issue that has been raised, HIS attests to compliance with 90.242 (a) (2) (ii): In consideration of possible crossmodulation and inter-modulation interference effects which may result from the operation of a Travelers Information Station in the vicinity of an AM broadcast station on the second or third adjacent channel, the applicant shall certify that he has considered these possible interference effects and, to the best of his knowledge, does not foresee interference occurring to broadcast stations operating on second or third adjacent channels. These possible interference effects have been considered by HIS. Steps taken to preclude them are a thorough site survey and listening tests before the FCC license is applied for and after the transmitter has been installed. In our experience over 25 years with approximately 1000 Traveler’s Information System installations there have been no cases of crossmodulation or inter-modulation interference between the Traveler’s Information Station and any commercial broadcast stations. Since the DRTXM4 Transmitter now being submitted for certification has essentially the same output driver stage configuration as all of its predecessors, we attest that our best engineering judgment is that this transmitter will not produce any unwanted interference with other broadcast services. We further attest that we will do everything we can to correct any interference situations should they arise in specific circumstances, both as stipulated by the FCC and as we have done in the past in the one case where there was interference with a particular brand of walkie-talkie, even though our equipment was judged by an FCC review not to be at fault. Thanks for your consideration in this matter. Sincerely, Thomas Hall Engineering Manager

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 February 10, 2006 RE: FCC ID: O2Q-DRTXM4_ATCB003168 Attention: Arnom Rowe I have a few comments on this Application. Please note that further comments may arise in response to answers provided to the questions below. 1. Please note that the MPE report classifies this device as a mobile rf transmitter with a minimum of 20cm separation. However, the manual does not mention mobile or a separation distance. Is this a licensed transmitter or is this a mobile transmitter? Please also note that the MPE report states this is a printer. Please explain and please provide any needed statement in the manual. 2. Please note that 90.242 mentions several attestations and certifications to be provided by the applicant. For example, please note that the 2 nd and third harmonic shown in the antenna terminal data is 6dB under the limit. Should the radio be subject to transmissions of an AM radio station, will these harmonics increase to cause interference to the licensed AM station due to cross-modulation or inter-modulation? Has this been considered? Please address this issue and any other pertinent issue in 90.242. 3. Please note that the MPE report states the highest power measured in the device was -18dBm. Please note that the highest power listed in the test report and 731 is 147dBuV (40dBm) or 10W. Please explain and please be consistent in all documentation. 4. Please note that licensed radio service devices are subject not only to conducted antenna spurious emissions under 2.1051 but are also subject to radiated spurious emissions from the cabinet as specified in 2.1053. The test report does not appear to have this information. Please provide the required erp radiated spurious emissions using antenna substitution methods as defined in TIA603. Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website.

Dward ATCB From: Arnie Rowe [[email protected]] Sent: 02/17/2006 12:54 PM To: Dward ATCB Subject: Highway Information Part 90 filing questions. 02/17/06 Hi Dennis, I have made the required updates to your email dated Febraury 10, 2006 and have uploaded on to the TCB web site. Please note that the MPE report classifies this device as a mobile rf transmitter with a minimum of 20cm separation. However, the manual does not mention mobile or a separation distance. I have uploaded an updated User’s Manual with the correct RF Exposure statement. Please also note that the MPE report states this is a printer. Please explain and please provide any needed statement in the manual. The "printer" used in the “RF Exposure Exhibit” was a boilerplate error and has been removed from the Mobile exhibit. I have uploaded the corrected page. Is this a licensed transmitter or is this a mobile transmitter? This transmitter is license under Part 90.242. Once the transmitter is installed, it remains at that location. Highway Information helps their customers attain the require license. Please note that the MPE report states the highest power measured in the device was -18dBm. Please note that the highest power listed in the test report and 731 is 147dBuV (40dBm) or 10W. Please explain and please be consistent in all documentation. I reran the formulas using 147 dBuv that was measured for the fundamental and uploaded it. Highway Information is working on number 2 of your email and as soon as I get it I will forward it to you. Thanks for your help, Arnie

RF Exposure Exhibit for Highway Information Systems, O2Q-DRTXM4 Mobile Devices are defined as a transmitting device designed to be used in other than fixed locations and generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. Therefore, this device is classified under section 2.1091 as a “mobile” device. Although this device is categorically excluded from RF exposure evaluation under Part 2, it can be shown that the device meets the limits used for evaluating other devices (those which are not excluded) under this section. Section 2.1091 for mobile devices state that the limits are given in 1.1310. The limit given in 1.1310 for general population/uncontrolled at 1700 kHz is a Maximum Permissible Exposure (MPE) limit of (180/f 2 ) mW/cm 2 . For 1700 kHz this limit is 62.283737 mW/cm 2 . The FCC OET Bulletin 65 Section 2 can be used to determine compliance with guidelines for human exposure to RF radiation. We will use equation 3 of that section for predicting RF fields. S = PG 4πR 2 S = power density (units e.g. mW/cm 2 ) P = power into to the antenna (or power output) (units e.g. mW) G = power gain of the antenna (worst case = 1) R = distance to the center of antenna (units e.g. cm) The highest power measurement for this device is 40 dBm. For this prediction we will use a worst-case power of 40 dBm or 10 Watts. Since the device is “mobile”, we will use a worst-case distance of 20 cm. For worst-case antenna gain, we will use a gain of one. Using equation 3 of OET Bulletin 65 Section 2, the power density is calculated to be 1.990446 mW/cm 2 . This is well within the 62.284 mW limit given in 1.1310.
