However, I would like to know if each receiver has its own antenna or do they need to share the same antenna?
All we need is :
- one receiver with a 500 Khz bandwith and one antenna,
- one or more receiver with a 48 KHz bandwith and its own antenna (miniwhip).
It would be great to use GNU radio as PC side application.
In case of SDR Transceiver, each of the two receivers is connected to a separate RF input: RX1 is connected to IN1 and RX2 is connected to IN2. It's possible to use this project with GNU Radio via the gr-osmosdr blocks or via the small custom blocks written in Python. 48 kHz can be obtained from 50 kHz with the sample rate conversion done by a GNU Radio block. It's also possible to make a custom FPGA configuration with just two receivers and the sample rate conversion can be taken from SDR transceiver compatible with HPSDR
