Install

$ pip install rf-info

Command Line Usage

$ rf-info <frequency> [<units>] [<country>]

Frequency format examples:

$ rf-info 89910000
$ rf-info 23,450,000
$ rf-info 12,634.534
$ rf-info 12_000_000
$ rf-info 344_500.100

Also supports “Radio Display” frequency representation (Dotted notation):

$ rf-info 124.125.000
$ rf-info 1.500.125.000
$ rf-info 000.012.500

Unit examples: hz, khz, Mhz, Ghz (Case Insensitive):

$ rf-info 4.5 ghz

Country examples (2 digit abbriviation, 3 digit abbriviation, 3 digit number, or full name) US, USA, 040, JPN, Spain (Case Insensitive):

$ rf-info 144.400.000 hz US
$ rf-info 88 mhz JPN

Python Library Usage

>>> from rf_info import Frequency
>>> freq = Frequency('144.890.000')
>>> freq.details()

Returns a dictionary:

>>> {'display': '144.890.000', 'units': {'hz': 144890000, 'khz': 144890.0, 'mhz': 144.89, 'ghz': 0.14489}, 'wavelength': '2m', 'itu': {'number': 8, 'band': 'Very High Frequency', 'abbr': 'VHF'}, 'ieee': {'band': 'VHF', 'description': 'Very High Frequency'}, 'nato': {'band': 'A'}, 'ism': {'band': None, 'description': None}, 'waveguide': {'band': None}, 'microwave': {'band': None, 'allocation': None}, 'country': {'name': 'United States of America', 'abbr': 'US'}, 'broadcasting': {'allocated': False, 'details': ()}, 'wifi': {'allocated': False, 'details': None}, 'amateur': {'allocated': True, 'modes': 'CW, Phone, Image, RTTY/Data', 'license': 'Tech, General, Extra', 'power': 'MAX'}, 'satellite': {'allocated': False, 'name': None, 'sat-id': None, 'link': None, 'modes': None, 'callsign': None, 'status': None}, 'services': None, 'station': {'fixed': False, 'mobile': False}, 'ieee_allocation': {'primary': ('Amateur', 'Amateur-Satellite'), 'secondary': (), 'notes': ('[5.216]: Additional allocation: in China, the band 144-146 MHz is also allocated to the aeronautical mobile (OR) service on a secondary basis.',)}}

Or you can get individual items directly:

>>> freq.itu
>>> freq.itu['band']
>>> freq.wavelength
>>> freq.ieee_allocation['primary']

Also supports adding and subtracting frequencies. Either a frequency object, int, or string representation of a frequency, returns a new frequency object:

>>> new_freq_object = Frequency('001.123.000') + Frequency('7', 'khz')  # Adds 7 khz to 1.123 mhz
>>> new_freq_object = Frequency('1', 'mhz') + 15000  # Adds 15 khz to 1 mhz
>>> new_freq_object = Frequency('123,000') - '000.007.000'  # Subtracts 7 khz from 123 khz
