SatHunter 4+

SatHunter helps IC-705 owners make satellite contacts with ease.

It provides aids for aiming the antenna at the satellite, and controls the IC-705 via bluetooth, adjusting the up/down frequencies automatically with doppler shifts.

Features:

* Simple control
- Connect to your IC-705 via Bluetooth, select a bird, select a transponder, then you only need to worry about rotating the antenna.
* Intuitive sky view
- Point your iPhone in the same direction as the antenna, then turn your antenna according to the indicator.
* Full doppler tuning
- For FM satellites, your IC-705 will always tune to the right frequency thanks to real-time doppler prediction and great frequency stability of IC-705
- For linear satellites, the uplink frequency automatically and correctly matches the downlink frequency when tuning.
* Updatable satellite and transponder database
* Open source software: https://github.com/brills/SatHunter/tree/main

Be a good operator when operating half-duplex. Avoid busy satellites. Always listen before transmitting.
