Getting started with the OARC Logger

Welcome to OARCs Logging website.

This was designed to support members of the OARC to log QSOs.

It allows OARC members to log all their contacts for either individually, or by importing an ADI file.

How to Get Started

This logger can be used in a couple of modes, we will start with the most simple and build from there

  1. Capture and display existing log files in the ADI format
  2. Live logging of SOTA / POTA / Portable operations of other events
  3. Full QSO management, including Station Configuration and QSL management

Registration and Logging in


Registration is very simple. Click on Sign Up (Green Button in top right of the nav bar), and complete the form.

Logging in

Click on Login (Grey Button next to Sign Up), and fill in your username and password.

Sucessful login will send you to your Profile Page

Users, Callsigns and Stations


This logger collects all your Callsigns, QSOs, Events, Station Configurations, Rigs and Antennas under you as a user. You created a username when you registered and it is this username that determines what data is yours in the logger.

Other users see all of their data by logging in as themselves. It is possible for an individual to set up more than one user account and manage callsigns indidviudally, but it is not the recommended mode of operation.

A user has one or many Callsigns. Callsigns have one or many QSOs. A QSO can only belong to a single Callsign, and a Callsign to a single User.

A user has one or many Station Configurations. These are used to prepopulate QSOs with information about your station.

A QSO can be part of none, or many Events.

A QSO was made by a configuration which consists of a rig and antenna combination (optional)


Callsigns should be familar to all users. In this logger, we take the callsign as the callsign used to make the QSO. This includes any prefix, suffix or RSL

Adding Callsigns

You can add as many callsigns as you like, for example, I currently have:

  • M7SMU - my foundation
  • 2E0UMS - my intermediate callsign
  • 2E0UMS/P - my intermediate portablem, still used for 2m contesting.
  • M0SMU - my full callsign
  • M0SMU/P - my full callsign portable used for SOTA

I might add MW0SMU if I go across the Severn and operate out of Wales


What is an Event?

An event is a collection of QSOs related in time, type or theme. For example, a SOTA activation of a summit or a pass of a Satellite, or a contest or field day. Any collection of QSOs that you might want to find later. It could even be used to seperate your QSOs by location (like Home or an alternate location)

Adding Events

Adding Events is as simple of clicking on your events in the menu bar and clicking Add Event at the bottom of the page. It is best to put in a good description of your event for later. The suggestion is to describe the event fully, for example "SOTA Activation of G/SC-010 in Aug 2023" or "SO-50 Pass on 12 June 2022".

Note that changing the type of Event will show different detail boxes, like SOTA reference or Satelitle Name, this information is used in any QSOs made against the event, so it can be used to save time when on the event.


Adding QSOs individually

A QSO is added to a callsign and may be part of an event and have a configuration associated with it.

You can add a QSO from the Profile Page (click Profile in the top right) by selecting New QSO against the callsign. Or, drill down to the callsign and click Add QSO.

A more advanced use case is to go to an Event like a SOTA activation or a Satellite event and click Add QSO. This will give you a simpler form to quickly capture the key details of the QSO. You can add a QSO to multiple events by selecting more than one Event.

Using Events with QSOs

As well as logging events against a Callsign, a QSO can be logged against an event(s). Select the primary event, and there is an Add QSO button at the bottom. Depending on the type of event, you will see a quick capture form and a list of QSOs logged against the event.

Importing QSOs

Any valid ADI file (ADIF) can be imported into the Logger.

QSOs imported from ADIF will automatically be assigned to your callsigns. If you import QSOs against callsigns you haven't registered, then simply add your callsign and those QSOs will be available to you.

Note that invalid ADIF will not be supported. It is advised that you check your ADIF is valid before attempting to import it into the Logger.

An excellent online editor is available: K1MU ADIF validator can be used to check your files. The most common issues are including non-standard characters in the text fields.
