 # ESP32 Codec2/OPUS DV Handheld Transceiver
 
 ## Introduction
-This project is a hobby/amateur/toy/educational radio ESP32 based LoRa/FSK Codec2/OPUS DV 3d printed handheld trasceiver a.k.a. walkie-talkie, which is using 1W E22-400M30S (SX1268) radio module (UHF, 70cm band) or optionally 100mW RA-01/RA-02 (SX1278) module. 
+This project is a hobby/amateur/toy/educational radio ESP32 based LoRa/FSK Codec2/OPUS DV 3d printed handheld trasceiver a.k.a. walkie-talkie, which is using 1W/2W E22-400M30S/E22-400M33S (SX1268) radio module (UHF, 70cm band) or optionally 100mW RA-01/RA-02 (SX1278) module. 
 
 It mimics ordinary FM walkie-talkie, does not use any protocol for simplicity, just sends audio codec frames with pre-configured radio digital modulation.
