26960 - 27280 kHz Part 15 Beacons

No Part 15 compliant 27MHz beacons reported.

See the 11 meter / 27 MHz CB beacons page, HF beacons and the Part 95 Subpart C 27MHz RC - the 26-28 MHz RCRS remote control pages for additional information on beacons in this band. Numerous Part 15 devices, Part 95 systems and on-site pager systems, wide-area paging and data link networks operating in this band may act as de facto beacons.

22 meter band beacon kit

This beacon includes a custom programmed micro controller which sends the CW ID.

FCC Regulations

160 - 190 kHz 

15.217   Operation in the band 160-190 kHz.
(a) The total input power to the final radio frequency stage (exclusive of 
  filament or heater power) shall not exceed one watt.
(b) The total length of the transmission line, antenna, and ground lead
  (if used) shall not exceed 15 meters.
(c) All emissions below 160 kHz or above 190 kHz shall be attenuated at
  least 20 dB below the level of the unmodulated carrier. Determination
  of compliance with the 20 dB attenuation specification may be based on
  measurements at the intentional radiator's antenna output terminal
  unless the intentional radiator uses a permanently attached antenna, in
  which case compliance shall be demonstrated by measuring the radiated
  emissions.


13560 kHz 

15.225   Operation within the band 13.110-14.010 MHz.
  (a) The field strength of any emissions within the band 13.553-13.567
  MHz shall not exceed 15,848 microvolts/meter at 30 meters.
  (b) Within the bands 13.410-13.553 MHz and 13.567-13.710 MHz, the field
  strength of any emissions shall not exceed 334 microvolts/meter at 30
  meters.
  (c) Within the bands 13.110-13.410 MHz and 13.710-14.010 MHz the field
  strength of any emissions shall not exceed 106 microvolts/meter at 30
  meters.
  (d) The field strength of any emissions appearing outside of the
  13.110-14.010 MHz band shall not exceed the general radiated emission
  limits in §  15.209.
  (e) The frequency tolerance of the carrier signal shall be maintained
  within ±0.01% of the operating frequency over a temperature variation
  of −20 degrees to +50 degrees C at normal supply voltage, and for a
  variation in the primary supply voltage from 85% to 115% of the rated
  supply voltage at a temperature of 20 degrees C. For battery operated
  equipment, the equipment tests shall be performed using a new battery.
  (f) In the case of radio frequency powered tags designed to operate
  with a device authorized under this section, the tag may be approved
  with the device or be considered as a separate device subject to its
  own authorization. Powered tags approved with a device under a single
  application shall be labeled with the same identification number as the
  device.


26960 - 27280 kHz 

15.227   Operation within the band 26.96-27.28 MHz.
  (a) The field strength of any emission within this band shall not
  exceed 10,000 microvolts/meter at 3 meters. The emission limit in this
  paragraph is based on measurement instrumentation employing an average
  detector. The provisions in §  15.35 for limiting peak emissions apply.
  (b) The field strength of any emissions which appear outside of this
  band shall not exceed the general radiated emission limits in §  15.209.

49.82 MHz - 49.90 MHz (49 MHz band)

See also: Remote Control - 49 MHz R/C Frequencies and the Part 15 page.

15.235 Operation within the band 49.82-49.90 MHz. (a) The field strength of any emission within this band shall not exceed 10,000 microvolts/meter at 3 meters. The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The provisions in § 15.35 for limiting peak emissions apply.

(b) The field strength of any emissions appearing between the band edges and up to 10 kHz above and below the band edges shall be attenuated at least 26 dB below the level of the unmodulated carrier or to the general limits in § 15.209, whichever permits the higher emission levels. The field strength of any emissions removed by more than 10 kHz from the band edges shall not exceed the general radiated emission limits in § 15.209. All signals exceeding 20 microvolts/meter at 3 meters shall be reported in the application for certification. (c) For a home-built intentional radiator, as defined in § 15.23(a), operating within the band 49.82-49.90 MHz, the following standards may be employed: (1) The RF carrier and modulation products shall be maintained within the band 49.82-49.90 MHz. (2) The total input power to the device measured at the battery or the power line terminals shall not exceed 100 milliwatts under any condition of modulation. (3) The antenna shall be a single element, one meter or less in length, permanently mounted on the enclosure containing the device. (4) Emissions outside of this band shall be attenuated at least 20 dB below the level of the unmodulated carrier. (5) The regulations contained in § 15.23 of this part apply to intentional radiators constructed under the provisions of this paragraph. (d) Cordless telephones are not permitted to operate under the provisions of this section. See Part 15 subsection regarding analog 49 MHz cordless phones: 15.233.
