Re: #FCC #DigitalModes: New Petition for Rule Making RM-11831 #fcc
Kolarik contended in his petition that FCC action stemming from ARRL’s 2013 “symbol rate” Petition for Rule Making could increase congestion (i.e., interference) problems. In July 2016, the FCC in WT Docket 16-239 proposed to revise the Part 97 rules to eliminate current baud rate limitations for data
For a 'technical person' its difficult to assimilate the position's taken in the petition , appears to be based on
obsolete concepts ?.
Take the 300 baud max rate , technology has advanced to the point , this this is no longer relevant, OFDM has now rendered high speed serial carrier systems to be obsolete , In a series of tests , carried out , comparing the VARA modem against other systems , VARA HF provided higher data transfer , at lower power levels than Pactor 4 , in either direct or nivs path..
The on-air carrier rate for vara is round 37 Baud , maintaining compatibility , with 'all' propagation modes

Channel congestion / interference
Making no reference to the benefits of 2G , in terms of bandwidth efficiency/access , although , apparently well versed in the subject's , would of expected some solution to the issues , again , seeking to diminish, rather than innovate ?
