ARRL says no to Encrypted Amateur Radio Communications

The ARRL is calling on the FCC to deny a Petition for Rule Making in RM-11699. This is a request that seeks to permit the encryption of certain amateur communications during emergency operations or related training exercises. Amateur Radio Newsline’s Norm Seeley, KI7UP, is here with the details:

As we previously reported, earlier this year the FCC accepted for filing a Petition for Rulemaking from Don Rolph, AB1PH, designated as RM-11699 and put it on public notice. In it Rolph suggested that an additional exception to Part 97.113 be made to permit encrypted communications when hams are participating in emergency services operations or related training exercises which may involve information covered by medical privacy requirements or other sensitive data. This could include logistical information concerning medical supplies, personnel movement or any other data designated by Federal authorities managing relief or training efforts.
But on July 8th the ARRL filed to oppose the AB1PH rules change request. The ARRL says that in its view there is no factual or legal basis for the assumption that encryption of transmissions is necessary in order to continue and enhance the utility of amateur radio emergency and disaster relief communication. The ARRL also characterized as erroneous the assumption that encryption of certain information may be required under the provisions of the Health Insurance Portability and Accountability or HIPPA Act.

The ARRL is not alone in this view. Several other commenters on RM-11699 have also pointed out that the restrictions imposed by HIPPA can be overlooked in time of a dire emergency.

HOW TO READ PROPAGATION NUMBERS

The A index [ LOW is GOOD ]

  • 1 to 6 is BEST
  • 7 to 9 is OK
  • 11 or more is BAD

Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.

A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.

SFI index [ HIGH is GOOD ]

  • 70 NOT GOOD
  • 80 GOOD
  • 90 BETTER
  • 100+ BEST

The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.

Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.

K index [ LOW is GOOD ]

  • 0 or 1 is BEST
  • 2 is OK
  • 3 or more is BAD
  • 5 is VERY VERY BAD

The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.

A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
