QRZ

QRZ.com elixir client for amateur radio callsign and DXCC lookups through their XML Data Service.

Queries require a QRZ account with an active XML Logbook Data Subscription.

Installation

The package can be installed by adding qrz to your list of dependencies in mix.exs:

def deps do
  [
    {:qrz, "~> 0.1.3"}
  ]
end

Usage

See the QRZ module documentation for additional details.

Login

Login to get session key to use for lookups. Queries that result in session expiration will return an error tuple denoting it, requiring a login call to get a new session key.

{:ok, session} = QRZ.login("username", "password")
#=> 
# {:ok,
#   %QRZ.Session{
#     key: "d0cf9d7b3b937ed5f5de28ddf5a0122d",
#     count: "6124",
#     sub_exp: "Sat Mar  8 00:00:00 2025",
#     gmt_time: "Wed Oct 18 17:09:55 2023",
#     message: "",
#     error: ""
#   }}

session.key
#=> "d0cf9d7b3b937ed5f5de28ddf5a0122d"

Callsign Lookup

Note: Currently every field is returned as a string, future versions may eventually cast numerical and date related values.

#   %QRZ.Callsign{
#     call: "AA7BQ",
#     xref: "",
