My goal is : - HF TRx - GPS receiver (ublock6M) - UHF TRX - RTL SDR receiver - Dual CC1101 (868MHz) separate antenna socket - Dual CC1101 (432MHz) separate antenna socket - Dual RF24L01 (2.4GHz) separate antenna socket - ALFA AWUS036NH 2W wireless adapter, separate antenna socket - Internal speakers (stereo) with PA - 20000mAh battery - USB Charging 65W PD (5V 3A) - and more .... See You soon ...
