Day and night are live. The satellites and layers show what KEPS draws from its live feeds.

KEPS

Satellite station software for amateur radio

Tracks the birds, turns the antennas and tunes your IC-9700, Doppler and all, on a live world map - with an SDR, SatNOGS, FT4, SSTV, APRS and a logbook with QRZ and LoTW.

VOICE AUTO-TUNE

Talk, and you're on frequency

On a linear bird, just start talking. KEPS lines up MAIN, your uplink, with SUB, your downlink, from your own voice, then keeps them together through the whole pass, Doppler and all.

  • No whistling into the mic, no hunting for yourself
  • Stays with you as the bird crosses the sky
  • One press of TUNE when you'd rather not talk
  • On the PC and on Android

THE IC-9700, OVER USB OR YOUR NETWORK

See the passband, click to tune

Plug the 9700 into the PC's USB, or reach it over your network from the PC or the tablet. Its spectrum and waterfall come up live in KEPS: see who's on the bird, click a signal, and you're tuned to it.

  • USB or the 9700's network port, a setting away
  • Click a station: the downlink and the uplink move together
  • Doppler taken care of while you work them
  • Listen to the 9700 right on the PC or tablet

Two ways to run it

The same KEPS on the shack PC or on a tablet, built from the same code.

What it does

One program for the whole satellite station.

Tracking & the map

  • Passes for every amateur satellite
  • A live world map with day and night
  • Layers: sky, ham radio, weather, earth, traffic
  • AOS alarms, and passes you can skip
  • Built-in frequencies for the amateur birds

The IC-9700

  • Doppler on linear and FM birds
  • Tap a signal on the passband to work it
  • Voice auto-tune: MAIN lined up with SUB as you talk
  • RF power, and SO-50's arming tone
  • Parked between passes

Antennas

  • Green Heron RT-21, PstRotator, CSN S.A.T.
  • Flips over a pass that crosses the stop
  • Point anywhere on a map, with an S-meter
  • Parked after a pass
  • Passes off when you just want to listen

The SDR (PC)

  • An RTL-SDR as a second receiver
  • Spectrum, waterfall and every mode
  • Bookmarks and scan
  • Recording, and SYNC with the 9700
  • Meteor-M pictures decoded as they come

Digital modes

  • FT4 built in, worked like WSJT-X
  • Auto power, so you come back at 0 dB
  • SSTV pictures from the ISS and the cubesats
  • APRS through the ISS
  • Telemetry beacons decoded (PC)

Log & SatNOGS

  • An ADIF logbook, contacts on the map
