As I read it, this fellow is petitioning the FCC to allow digital communications with a bandwidth up to 2.8 kHz in what is currently the CW/digital portions of the HF bands. As one commenterÂ*pointed out, To permit data transmissions with a 20 dB bandwidth of 2800 Hz throughout the non-voice segments of the 3.5-30 MHz. This would constitute a significant source of interference for narrow-band modes. This includes modes such as PSK-31. Please consider filing a comment opposing this petition. DanÂ* SB QST @ ARL $ARLB016 ARLB016 ZCZC AG16 QST de W1AW ARRL Bulletin 16 ARLB016 From ARRL Headquarters Newington CT May 12, 2016 To all radio amateurs SB QST ARL ARLB016 ARLB016 Missouri Radio Amateur Petitions FCC to Designate SymbolÂ*Communication Subbands James E. Whedbee, N0ECN, of Gladstone, Missouri, has petitioned theÂ*FCC to designate Morse (radiotelegraphy) Amateur Radio band segmentsÂ*as symbol communication subbands. The FCC has invited comments onÂ*his Petition for Rule Making (RM-11769), filed on May 2. ArguingÂ*that retaining the current regime of legacy CW subbands has provenÂ*to be grossly inefficient, Whedbee said hed like to see the FCCÂ*delete all privilege restrictions that limit any part of the AmateurÂ*Radio spectrum to Morse code to the exclusion of other modes. RM-11769 can be found on the web atÂ*http://apps.fcc.gov/ecfs/comment/view?id=60001692464 . Nostalgia for retention of Morse code telegraphy-only subbands isÂ*also an insufficient reason to avoid moving forward to [the]Â*elimination of such subbands, because nothing about this PetitionÂ*suggests the elimination of the mode itself, only that it not be theÂ*sole authorized mode in the subject subbands, Whedbee told the FCC. Whedbee characterized CW-only subbands as an excessive regulatoryÂ*constraint, as well as a poor use of the spectrum concerned. HeÂ*proposed that the FCCs Part 97 rules reflect the ultimate form ofÂ*communication reproduced at the receiving end. As he explained it,Â*his regulatory scheme would break down modes into three categories Â*symbol communication mode for CW, digital, and other emissionÂ*modes that reproduce a discrete symbol on the receiving end voiceÂ*mode, and image mode. [C]ontinuing regulation by specific emission designator is provingÂ*to be onerous with changes to the state of the art, Whedbee said.Â*Accordingly, to continue developing the state of the art inÂ*radiocommunications, Amateur Radio needs to clearly get away fromÂ*regulating in that fashion and return to consideration of what the receiving end of the communication reproduces. He proposed that where the Part 97 rules refer to exclusiveÂ*radiotelegraphy allocations or subbands privileges be changed toÂ*reflect symbol communication modes. Where the rules prohibit voiceÂ*and image modes, he would revise the rules to reflect symbolÂ*communication modes. In situations where current rules prohibitÂ*symbol communication modes other than Morse, that voice and imageÂ*modes would be permitted, with an exception for manually keyedÂ*radiotelegraphy. For example, he would drop the distinction between 75 meters and 80Â*meters, authorizing symbol communication modes between 3.5 MHz andÂ*3.65 MHz, and voice and image modes between 3.65 MHz and 4 MHz, withÂ*manual radiotelegraphy authorized throughout the band. Whedbee told the FCC that, if his Petition is accepted for filingÂ*and put on public notice, he would submit an appendix spelling outÂ*proposed service rules as part of his Petition. Commenters have 30 days to respond to Whedbees Petition. NNNN /EX The post Missouri radio amateur petitions FCC to designate symbol communication subbands appeared first on KB6NUs Ham Radio Blog. |
