HELP PROTECT OUR DIGITAL BAND SEGMENTS – STOP RM-11708

RTTY, digital, and CW users are strongly encouraged to post their rebuttal comments to the FCC regarding a very poorly developed ARRL proposal that requested the FCC to allow wide digital transmissions up to 1800 baud (equivalent to 2.8 KHz) allegedly so that Pactor-4 could operate in our bands.  The FCC made this even worse by proposing to eliminate any baud rate (symbol rate) restrictions whatsoever.  This would create QRM mayhem in the traditional RTTY and digital sub-bands (including the CW portions).  Pactor-4 is a commercial proprietary mode which is essentially encrypted and which cannot be monitored unless one owns the expensive hardware and purchases a user license.   This goes completely against the spirit of amateur radio by allowing wide signal encrypted stations which cannot be identified nor monitored for content to operate within our digital sub-bands.  It is also completely counter to the concept of encouraging the development of new amateur narrow bandwidth digital modes (such as PSK, Olivia, JT-65, MFSK, Contestia, DominoEX, etc.).

The use of proprietary encrypted commercial wide digital modes within the amateur bands goes completely against the spirit of amateur radio, such transmissions ought to be at minimum, restricted to portions of the band away from the traditional areas where digital and CW operate.  Therefore, you are encouraged to send a comment to the FCC opposing RM-11708 for these reasons:

  • Protect narrow bandwidth transmission users (RTTY, digital, CW) from interference by wide-bandwidth digital transmissions. Experiments with wide bandwidth modes should be kept in a separate spectrum segment away from narrow bandwidth users.
  • Recommend that the FCC set aside a narrow bandwidth segment allocation in the amateur bands restricted to 400 Hz bandwidth transmissions. (i.e. the traditional CW/RTTY/Digital band portions).  This narrow bandwidth segment ought to be at minimum 125 Khz wide to accommodate all traditional narrow bandwidth communications (such as 14000 to 14125).
  • Limit wide bandwidth transmissions to 2.7 KHz in the balance of the bands below 29.5 MHz
  • Recommend that no digital transmissions be allowed in the amateur bands which cannot be monitored by open-source, publicly available software applications. Proprietary commercial encrypted operations within amateur radio should be considered illegal as per past FCC rule.

Please send your RM-11708 rebuttal comments to the FCC by no later than September 25 at https://www.fcc.gov/ecfs/filings.  It is critical that we protect our RTTY, digital, and CW band segments from what will otherwise result in QRM mayhem.
