Features
Everything it does, in plain words.
Thirteen screens, one job each. Read the four steps first if you are new — they take about five minutes and turn the console into a tool that answers for your station rather than the world in general.
Start here. Four steps, about five minutes.
01 — Tell it where you are
Open Station and type your callsign. Let the app read your location once and turn it into a grid square, or type the square yourself. Every other screen now answers for your station instead of the world in general.
02 — Ask if it is worth switching on
Open Conditions. It gives you a verdict in one line and names the band carrying best from where you are. It is allowed to say no, and it tells you when the Sun is the reason.
03 — Find somebody to work
Open The Skip. It draws the signals receivers are hearing right now and marks the operators calling from parks. A chip on each row tells you whether your logbook has ever seen them.
04 — Log the contact
Press L anywhere, type the callsign, press Enter. It saves to your device with or without a signal, and your country and state counts climb as you go.
Every screen, one by one.
14 MODULES
01
Ops
Live map
Quick log
One screen
Shows what is happening on the bands right now, and logs a contact without leaving the page.
Watch the map — every curve is a signal a receiver somewhere actually heard in the last few minutes.
Press L, type a callsign, press Enter. The contact is in your log.
Click any marker to see who it is, how far away they are, and which way to point.
Read today at a glance: contacts logged, stations on the air, and your next satellite pass.
02
Conditions
Plain verdict
Measured vs forecast
Grey line
Answers the question you ask before every session: is it worth switching the radio on right now?
Read the verdict in one line, with the band carrying best from your own location.
Compare what people really heard in the last hour against what the forecast predicts — the screen keeps them apart.
Find out when the Sun is swallowing your band, so you stop blaming your antenna.
Catch the next sunrise and sunset window, when the low bands suddenly reach much further.
03
The Skip
Live paths
Operators on air
Checked against your log
Draws where signals are landing worldwide this minute, and marks the stations you have never worked.
Follow real reception reports as they arrive, each one a path the sky actually carried.
Read the chip beside an operator before you call — new country, new grid, new callsign, or a quiet 'worked'.
Narrow the map to one band and read the distance and bearing from your own antenna.
Zoom and drag the map to your own part of the world, then click a row to isolate that single path.
04
Logbook
Works offline
No account
Counts countries
Logs your contacts on your own device, and needs neither a signal nor a sign-in to do it.
Add a contact in seconds — band and mode carry over from the last one, so a run changes one field.
Watch your country and state counts climb as you log; the app works the country out from the callsign itself.
Bring in a log from any other program, and take yours out again whenever you want it elsewhere.
Keep working in a dead spot — nothing about saving a contact touches the network.
05
Satellites
Passes over you
Sky chart
Calendar reminder
Tells you when the amateur satellites fly over your location, and where to point when they do.
Read the next passes for your square, with the time each one rises and sets.
Follow the pass across the sky chart — the centre is straight overhead, and each dot is a minute.
Save a pass to your own calendar and get a reminder five minutes before it starts.
Check how fresh the orbit data is before you trust a time; the screen says so instead of hiding it.
06
Footprint
Who heard you
Real distances
Shareable link
Shows where a station is really getting out, drawn from the receivers that decoded it.
Type any callsign and see every receiver that picked it up.
Read how far each report travelled, and on which band.
Trace your own callsign to find out where you reached last night.
Send the result to a friend — the callsign sits in the address, so the link opens the same picture.
07
Privileges
May I transmit here?
Two licences
Sourced
Answers where two licences can legally meet — and whether you may use one exact frequency.
Type a frequency and get a straight yes or no for your licence, with the power limit that applies.
Pick your country and the other operator's, and read the bands you both hold.
See what already uses that spot: beacon slots to keep clear of, and the frequencies people gather on by habit.
Follow the link on any record to the regulator's own document — this is a well-checked summary, not the law.
08
Nets
Running now
Your clock
Every row checked
Lists the scheduled on-air meet-ups, and tells you which ones are running this minute.
See what is on the air now, in your own clock as well as UTC.
Read the frequency, mode and language before you tune in.
Check whether the path from your station is even workable before you go looking for it.
Put a net in your calendar as a repeating reminder, and follow the link it was checked against.
09
The Bench
Antenna maths
Real radiated power
Fully offline
Does the workshop maths — antenna lengths, cable loss, real radiated power — with no network at all.
Cut a dipole or a vertical to the right length for your band, with the formula printed beside the answer.
Turn transmitter power, cable loss and antenna gain into the figure your licence limit actually means.
Work out the distance and bearing between two locations, in a field, with the phone in aeroplane mode.
Learn Morse letter by letter with the trainer, at full speed from the first minute.
10
Morse
Practice partner
Three levels
Public rooms
A room for practising Morse code, with a partner that answers what you actually send.
Key with the spacebar, type dots and dashes, or type plain words and let the room send them for you.
Work a full practice contact against a partner you set to basic, pro or expert — it slows down when you ask.
Step into a public room and key with real operators; every message clears itself after a day.
Hide the text and copy by ear, then tap a message to check what was really sent.

Comms
Phonetics
Q-codes
One contact, four ways
The reference for how operators actually talk, one press away while you practise.
Look up the phonetic alphabet, the signal report system, and the codes worth knowing.
Read the same contact written out four ways, so you know how each mode sounds before you try it.
Learn the shape every contact follows — call, answer, exchange, close — before your first one.
Keep it open beside the practice room: it slides in over the channel, and works with no signal.

Station
Callsign · location
Set once
Stays on device
Two fields — your callsign and your location — turn every other screen into your answer.
Let the app read your location once and turn it into a grid square, or type the square yourself.
Everything then follows: distances, bearings, pass times, sunrise windows, and the bands you may use.
Share four characters of your location at most — about a hundred kilometres — unless you choose otherwise.
Read the register while you are here: every feature says where its data comes from, and what was left out.

Callsign alerts
Community
Your own corner of the console: how far your log has reached, alerts that watch a callsign for you, and the people using the app.
Sign in, then click your callsign in the top bar. That is the door — there is no menu row for it.
Watch a callsign and get told the moment a receiver hears it, or it starts calling from a park. The bell in the top bar collects every alert.
Turn on push and those alerts reach your phone as notifications, even with the app closed.
Ask for a feature, comment on one, or report a bug on the community board — or send the maintainer a private note nobody else sees.
Open the vault from here: restore points, the original files you imported, and every change your log has been through.

Shack display
Wall screen
Glanceable
Nothing to shut down
Turns any spare screen into a wall display you can read from across the room.
Leave it running for the clock, the line between day and night, and the solar numbers.
See which beacon is transmitting this second, and when your next satellite pass starts.
Tap the screen, or press Escape, to come back to the console.
Keep it for good — it is the same app as every other screen, so there is no service behind it to switch off.
What it will not do.
It never transmits
There is no path from this app to a transmitter. It reads, calculates and logs. Keying the radio stays your job, which is also the only arrangement your licence allows.
It does not make you sign up
Every screen except the community board and the callsign alerts works signed out, offline, for good. An account adds things; it never unlocks the basics.
It keeps your location yours
Your grid square stays on your device. Where anything is shared, four characters go out, which covers about a hundred kilometres. Sharing anything finer is a switch you have to turn on yourself.
It does not fill gaps with guesses
When a source cannot be reached, or a band-plan record cannot be checked twice, the screen says so and shows nothing there. A wrong frequency costs you an evening at best, so absence beats invention.
