Centinel DX coordinates in real time which operator is working each band and mode, keeps a duplicate-free log, and shows the activity to anyone who wants to follow it — for any contest or activation you run.
No limit on contests or activations, on any plan.

Centinel DX is the platform where you run your amateur radio contests and activations: each operator claims their band and mode before transmitting, the system prevents collisions, and everyone can follow what's happening live.
The band/mode matrix locks each combination the moment someone claims it. No one else can take it until it's released.
Every QSO is checked against the activity log instantly: if that callsign has already been worked on that band and mode, the system flags it.
Anyone can check which stations are active right now in a contest, with no account or password needed.
From whoever's organising to whoever just wants to follow the contest from home.
Scoring, tracking, even the QSL — without leaving the platform.
See on a map who's receiving you right now, with real data from PSKReporter — no need to wait until the contest ends to know if you're being heard.
Turn on an automatic QSL per contact or a single summary certificate, with your own template — each participant downloads it with their callsign, no manual sending required.
A text channel to coordinate your team while the contest runs, with mentions and history — without leaving the app.
Fixed per contact, a band table, or a band-and-mode table — set up whichever your own rules use, and the standings calculate themselves.
Assigned automatically in phone and CW, never duplicated even when several operators log at once, and flags any gap in the numbering.
From 160m to 70cm, plus PMR446, CB27 and the QO-100 satellite — with 13 modes, from SSB and CW to FT8, DMR or D-STAR.
Run as many contests and activations as you like during the year. The plan only changes based on how many operators you need per contest.

Accounts are set up by email: write to info@centineldx.com, we'll send you a form, and we'll activate the organiser account and each of your operators' accounts.
There's no self-service sign-up: every account is activated by hand, so organiser and operators are properly set up from day one.
Send an email to info@centineldx.com telling us which plan you need and what contest or activation it's for.
We'll send you a short form to set up the organiser account and each operator on your team.
As soon as the accounts are active, log in at login.centineldx.com and create your first contest.
No band collisions, no duplicate QSOs, with live tracking for anyone who wants to see it.
