## What is CallSign Check?

CallSign Check is the fast way to look up any amateur radio callsign. Type a
call, get the full picture — no account, no clutter, no waiting.

US LOOKUPS (FCC)
• Full license dossier from the FCC ULS database: name, license class,
  address, grant and expiration dates, FRN, and previous callsign
• Live prefix suggestions as you type — start with "W1A" and watch the
  matches roll in
• Station location on a map, with grid square
• Distance and beam heading from your location to the station — point your
  antenna with confidence (your position never leaves your device)
• Phonetic readout of every callsign, ready for the air

DX LOOKUPS (WORLDWIDE)
• Flip to VFO B and look up operators worldwide: name, country, DXCC
  entity, CQ and ITU zones, grid square, and QSL manager

VANITY CALLSIGN HUNTING
• Check whether a callsign is currently assigned before you file a vanity
  application
• Search the FCC database by name, city, state, ZIP, or license class with
  Advanced Search

BAND CONDITIONS AT A GLANCE
• Live HF propagation strip on the home screen: solar flux, A and K
  indices, and band-by-band day/night conditions

BUILT FOR OPERATORS
• Favorites and lookup history, stored on your device
• Share any station dossier with one tap
• Miles or kilometers, your choice
• A focused, dark, radio-room interface that does one thing well

CallSign Check is not a logger or a contest tool — it's the lookup app you
reach for when a call comes back to you and you want to know who's on the
other end. 73!

US license data comes from the FCC Universal Licensing System via
callook.info. DX data provided via callsigncheck.com. Band conditions
courtesy of N0NBH (hamqsl.com).
