TRX-DUO SDR new case PT.2
Final changes, just photos.
Final changes, just photos.
Now, everything I need doesn’t fit into the case. So I decided to replace the case.
Mounted: Connected: Receiving: Some marine freqs: Transmit:
Still need to figure out a case for esp32:
As it’s RedPitaya clone it’s compatible with Pavel’s Demin software from project «Red Pitaya notes» except that fact that 122.88Mhz 16Bit version of Red Pitaya based in the Xilinx Zynq 7020 FPGA and the clock of the 7010 version is 125Mhz and ADC is 14bit.
Some improvements.
Now i think it’s better to insert all filters in box and not to insert TRX-DUO (or another SDR).
While i experimenting with i2c I killed something on this bus or i2c on FPGA itself…
Normally in Red Pitaya we can use analog inputs 0 and 1 for DC output from SWR bridge without any changes in software.
Unfortunately that pins are not connected to FPGA in TRX-DUO.
