PETITION FOR RULE MAKING

INTRODUCTION

            1.  In comments filed in WP Docket No. 10-72,[1] with intention of making the best use of our national resource of our amateur service community for intercommunications related to emergencies, this petitioner recommended the reconstitution of the former Disaster Radio Service, Part 99.  The service model recommended to follow would be that of Military Affiliate Radio System sponsored by our Army, Navy and Marine Corps, and Air Force.[2]  This would enable easily modified amateur station apparatus is used by our seasoned amateur radio operators under rules dedicated to - and designed exclusively for - public safety and homeland security communications.  The attached Appendix 1 is this petitioner's proposed draft of such a rule part. 

DISCUSSION

            2.  These proposed rules are designed to enable our amateur service community to provide telecommunications services during a disaster without negatively compromising the integrity of our amateur radio service or our status as amateur radio operators.[3]  These draft rules are targeted toward providing ad hoc telecommunication networks in unpredictable emergency situations, when close cooperation between different government and non-government agencies is essential to providing fast response.  Specific and unambiguous provisions are made for disaster radio service station licensees and control operators to accept compensation while carrying out this work.  This approach resolves the contentious issue arising from addressing the need for better emergency telecommunications through a major redirection of our amateur radio service in places where it is regulated by the Commission.[4]

            3.  These draft rules borrow heavily from the current Part 97, the set of rules with which holders of Commission amateur service license grants are already most familiar.  Some 1610 questions concerning the rules in Part 97, as well as good amateur practices and the technology necessary to comprehending these rules and practices are contained in question pools from which are drawn the question sets that our 30,000 volunteer examiners administer to amateur operator license candidates practically everywhere. 

            4.  The disaster radio service would be used exclusively for doing what our amateur service community does best:  Providing emergency telecommunications through our ad hoc networks using our unique array of abilities: know-how capability, situational adaptability, technical flexibility, operator availability, et al.  These abilities exist because of the adaptive nature of our communication systems made possible only because of our practical hands-on familiarity with the underlying technology.  No other telecommunication service comes close to our amateur radio service in these abilities.[5]

            5.  Because the disaster radio stations and control operators would be drawn from our amateur radio service, these draft rules would authorize transmissions by rule rather than through additional license processing.  Transmitter power limits are such as to make unnecessary the RF environmental evaluation[6] otherwise mandatory for higher power transmissions.  Frequency privileges have been identified that would facilitate conversion of amateur station apparatus to disaster radio service coverage.  In the HF range, our amateur service 60 meter band - which is not a worldwide amateur service band - would be shared secondarily with the disaster service as would our VHF 1.25 meter band.  A new VHF band at 54-56 MHz[7] would be immediately adjacent to our amateur service 6 meter band.[8]  The other new VHF band would be at 174-178 MHz.[9]  That particular spectrum range is close enough to the amateur service 2 meter band[10] as to make possible a similar band plan for field simplex and repeater mobile and handheld radio voice and keyboard digital packet intercommunications.    

CONCLUSION

6.  There is, unquestionably, an enormous unmet demand for better telecommunications intercommunications available to emergency and disaster responders.  This petition offers the Commission a way to enable our amateur service community to help meet that challenge quickly with a trained and knowledgeable national reserve without negatively compromising the integrity of its very fountainhead, our amateur radio services.[11]

 (a) No DRS station transmission shall occupy more channel bandwidth than necessary for the information rate and emission type being transmitted, in accordance with good amateur radio practice.

(b) Emissions resulting from modulation must be confined to the channel or band available to the control operator. Emissions outside the necessary channel bandwidth must not cause splatter or keyclick interference to operations on adjacent frequencies.

(c) All spurious emissions from a DRS station transmitter must be reduced to the greatest extent practicable. If any spurious emission, including chassis or power line radiation, causes harmful interference to the reception of another radio station, the licensee of the interfering DRS station is required to take steps to eliminate the interference, in accordance with good engineering practice.

(d) The mean power of any spurious emission from a DRS station transmitter or external RF power amplifier transmitting on a frequency between 54-225 MHz must be at least 60 dB below the mean power of the fundamental. For a transmitter having a mean power of 25 W or less, the mean power of any spurious emission supplied to the antenna transmission line must not exceed 25 µW and must be at least 40 dB below the mean power of the fundamental emission, but need not be reduced below the power of 10 µW.

(f) The following standards and limitations apply to DRS station transmissions:

(1) No angle-modulated emission may have a modulation index greater than 1 at the highest modulation frequency.

(2) No non-phone emission shall exceed the bandwidth of a telecommunications quality phone emission of the same modulation type. The total bandwidth of an independent sideband emission (having B as the first symbol), or a multiplexed image and phone emission, shall not exceed that of a telecommunications quality A3E emission.

(3) Only a RTTY or data emission using a specified digital code listed in § 99.309(a) may be transmitted. The symbol rate must not exceed 300 bauds, or for frequency-shift keying, the frequency shift between mark and space must not exceed 1 kHz.

(4) Only a RTTY or data emission using a specified digital code listed in § 99.309(a) may be transmitted. The symbol rate must not exceed 1200 bauds, or for frequency-shift keying, the frequency shift between mark and space must not exceed 1 kHz.

(5) A RTTY, data or multiplexed emission using a specified digital code listed in §99.309(a) may be transmitted. The symbol rate must not exceed 19.6 kilobauds. A RTTY, data or multiplexed emission using an unspecified digital code under the limitations listed in §99.309(b) of this part also may be transmitted. The authorized bandwidth is 20 kHz.

(6) A RTTY, data or multiplexed emission using a specified digital code listed in §99.309(a) may be transmitted. The symbol rate must not exceed 56 kilobauds. A RTTY, data or multiplexed emission using an unspecified digital code under the limitations listed in § 99.309(b) also may be transmitted. The authorized bandwidth is 100 kHz.

(7) A RTTY, data or multiplexed emission using a specified digital code listed in §99.309(a) or an unspecified digital code under the limitations listed in § 97.309(b) may be transmitted.

(8) A RTTY or data emission having designators with A, B, C, D, E, F, G, H, J or R as the first symbol; 1, 2, 7 or 9 as the second symbol; and D or W as the third symbol is also authorized.

(9) Emission F8E may be transmitted.

(10) A data emission using an unspecified digital code under the limitations listed in §99.309(b) also may be transmitted. The authorized bandwidth is 100 kHz.

§99.309   RTTY and data emission codes.

 (a) A DRS station may transmit a RTTY or data emission using the following specified digital codes:

(1) The 5-unit, start-stop, International Telegraph Alphabet No. 2, code defined in ITU-T Recommendation F.1, Division C (commonly known as "Baudot").

(2) The 7-unit code specified in ITU-R Recommendations M.476-5 and M.625-3 (commonly known as "AMTOR").

(3) The 7-unit, International Alphabet No. 5, code defined in IT--T Recommendation T.50 (commonly known as "ASCII").

(b) A DRS station transmitting a RTTY or data emission using a digital code specified in this paragraph may use any technique whose technical characteristics have been documented publicly for the purpose of facilitating telecommunications.

(c) A DRS station may transmit a RTTY or data emission using an unspecified digital code, except to a station in a country with which the United States does not have an agreement permitting the code to be used. RTTY and data emissions using unspecified digital codes must not be transmitted for the purpose of obscuring the meaning of any communication. When deemed necessary by a District Director to assure compliance with these rules, a DRS station licensee must:

(1) Cease the transmission using the unspecified digital code;

(2) Restrict transmissions of any digital code to the extent instructed;

(3) Maintain a record, convertible to the original information, of all digital telecommunications transmitted.

§99.311   SS emission types.

(a) Emission type SS transmissions by a DRS station are authorized only for telecommunications between points within and between areas where the DRS is regulated by the FCC. 

(b)  Emission type SS transmissions must not be used for the purpose of obscuring the meaning of any communication.

(c) A DRS station transmitting emission type SS must not cause harmful interference to stations employing other authorized emissions, and must accept all interference caused by stations employing other authorized emissions.

(c) When deemed necessary by a District Director to assure compliance with this part, the DRS station licensee must:

(1) Cease emission type SS transmissions;

(2) Restrict emission type SS transmissions to the extent instructed; and

(3) Maintain a record, convertible to the original information (voice, text, image, etc.) of all emission type SS telecommunications transmitted.

§99.313   Transmitter power standards.

(a) A DRS station must use the minimum transmitter power necessary to carry out the desired telecommunications.

(b)  No DRS repeater station may transmit with more than 500 W ERP.

(c) Except for a DRS repeater station, no DRS station may transmit with a transmitter power exceeding 50 W PEP.

(d) No DRS station may transmit with an ERP exceeding 50 W PEP on the 60 m band. 

(1)  For the purpose of computing ERP, the transmitter PEP will be multiplied with the antenna gain relative to a half-wave dipole antenna or the equivalent calculation in decibels. A half-wave dipole antenna, 27 meters (87 feet) in length, will be presumed to have a gain of 0 dBd. 

(2)  Either manufacturer data on the antenna gain or calculations of the antenna gain must be maintained in the station records

[2]    Operated since 1925, the MARS now relies upon over 5,000 volunteer amateur operators who use their station apparatus for transmitting messages for our military on non-amateur service government radio channels.  Accepting as compensation surplus military radio apparatus and other perquisites is not an issue. 

[3]  SEC. 3. [47 USC 153](2) of the Communications Act of 1934; No. 1.56 of the international Radio Regulations (RR); and §§2.1(c) and 97.3(a)(4) define an amateur as a duly authorized person interested in radio technique solely with a personal aim and without pecuniary interest.

[4]    Practically every country authorizes the amateur radio service.  Most countries reportedly consider it to be a recreational activity.

[6]  In the amateur service, §97.13(c) requires the station licensee to perform the routine RF environmental evaluation prescribed by §1.1307(b), if the power of the licensee's station exceeds certain limits.

[7]  VHF 54-56 MHz is a portion of former VHF broadcasting channel 2.

[8]  The amateur radio service VHF 6 meter band is 50-54 MHz.

[9]  VHF 174-178 MHz is a portion of former VHF broadcasting channel 7.

[10]  The amateur radio service 2 meter band is 144-148 MHz.

[11]  §97.1 says that the rules in Part 97 are designed to provide an amateur radio service having a fundamental purpose as expressed in the principles of providing voluntary noncommercial communication public services, advancing the radio art, advancing technical and communication skills, expanding our reservoir of trained operators, technicians and electronic experts, and enhancing international goodwill.
