Oscar Papa Class
CX22OP
An offline-first operations console for radio amateurs — propagation you can actually check, a logbook that works with no signal, and proof of where your signal landed.

Overview
Is it worth turning the radio on?
CX22OP answers the question every operator asks before keying up: is the band open, from here, right now. It separates what is measured from what is modelled — live WSPR reception reports against the SWPC forecast — so you can tell a prediction from an observation. Around that sit a logbook that works with no network and no account, satellite pass times computed for your grid, a footprint trace showing which receivers actually decoded you, a mutual-privilege overlay for working across two licence regimes, and a nets directory in UTC. It installs as an app on any device, keeps your callsign and grid on that device, and costs nothing.
Free, and free of accounts. Your callsign, grid and log stay in the browser's own storage on your device — export ADIF whenever you want a copy elsewhere.

In the field
What you'd use it for.
01
Decide whether to turn the radio on, from your grid rather than a global average.
02
Log contacts in the field — a summit, a park activation, a dead spot — with no signal and no account.
03
Find out which receivers heard you last night, and how far the signal actually reached.
04
Plan a satellite pass with look angles computed for your own square, not a generic footprint.
05
Work out what two licence classes may legally share before calling CQ across a border.
06
Catch a net at the right UTC minute, on a frequency the path can plausibly carry.

Capabilities
What's inside.
01
Conditions — the truth panel
Observed and modelled, side by side and labelled as such: live WSPR beacon reports near your grid against the SWPC band forecast, plus grey line, sun elevation and space weather.
02
The Skip
A live propagation map drawing WSPR reception reports as great-circle paths and POTA activations as markers, filterable by band and mode, each with distance and bearing from your antenna.
03
Offline logbook
ADIF import and export, running entirely on-device. No network, no account, no sync step — contacts logged in a dead spot are still there when you get home.
04
Satellites
Pass prediction from current Celestrak element sets across a 96-object catalogue, with AOS times and look angles computed for your square.
05
Footprint
Trace your own callsign through WSPR reception reports to see which receivers decoded you and how far the signal carried — stated plainly as beacon data, not contacts.
06
Privileges overlay
Pick two licence classes from two countries and the screen draws the legal intersection: shared segments, permitted modes, and whose power limit binds.
07
Nets directory
What is running right now, in UTC and your local time, with a modelled answer to whether the path from your station is even plausible.
08
The Bench
An offline utility belt — antenna maths against a design frequency, a Morse trainer, and grid-square distance and bearing geometry. No network used.
09
Installs anywhere
A progressive web app: install it from the browser on Android, iOS, Windows, macOS or Linux, and it keeps working when the connection does not.
