# Introduction
|
|
**Turn your Android phone into real Amateur Radio HF/VHF/UHF APRS enabled Codec2 DV (digital voice) and/or FreeDV handheld transceiver.**
|
|
|
|
**Requires additional hardware (e.g. AFSK/LoRa), software (e.g. Direwolf) radio modem or analog transceiver with USB audio + VOX/USB CAT PTT control, such as MCHF or ICOM**

# Short Description
|
|
What you can do with this app:
|
|
- Use it with your KISS Bluetooth/BLE/USB/TCPIP hardware modem, such as LoRa/FSK/AFSK/etc, control its parameters by using "set hardware" KISS command
|
|
- Use it with KISS software modem using TCPIP, such as Direwolf
|
|
- Use it with your HF/VHF/UHF transceiver as a sound modem
|
|
- Use your phone as a software sound modem by using external USB OTG audio adapter (voice + data) or built-in phone speaker and mic (only data)
|
|
- Use your phone for FreeDV protocol voice communication together with HF transceiver, which supports USB OTG audio
|
|
- Control your external transceiver PTT by using USB serial CAT (or VOX if CAT PTT is not supported)
|
|
- Send and receive APRS position reports over FSK 300 (HF, TX only), AFSK1200 (VHF), FreeDV OFDM (HF)
|
|
- Send and receive APRS messages
|
|
- Send and receive raw Codec2 speech frames over KISS or inside APRS/AX.25 UI frames
|
|
- Use application as APRS digirepeater
|
|
- Use application as APRS-IS RX/TX iGate
|
|
|
|
# Requirements
|
|
- Android 7.0 (API 24) or higher
|
|
- Application could also be used with your Android network radio, such as Inrico TM-7, apk just needs to be installed over USB, see [Discussion](https://github.com/sh123/codec2_talkie/issues/4)
|
|
- Android 5.0, 5.1, 6.0 (API 21, 22, 23)
|
|
- Separate apk package is released with "legacy" suffix from legacy branch
|
|
- Modem, radio module or transceiver which supports [KISS protocol](https://en.wikipedia.org/wiki/KISS_(TNC)) or can process KISS or raw Codec2 audio frames over serial Bluetooth, BLE, USB or TCP/IP
|
|
- Analog transceiver with built-in or external USB audio adapter and VOX or USB CAT PTT control (such as MCHF or iCom IC-7x00 series)
