TRX-DUO SDR new case PT.1
Now, everything I need doesn’t fit into the case. So I decided to replace the case.
ur3lmz tansverter for trx-duo transceiver
Mounted: Connected: Receiving: Some marine freqs: Transmit:
Found a use for magnetic ribbon from old Roborock cleaner :)
Still need to figure out a case for esp32:
Binary files for Xilinx Zynq 7010 FPGA (TRX-DUO)
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.
SDR box — finally it fits into the case
Continue working on SDR Box
Some improvements.
Concept of the box has changed :)
Now i think it’s better to insert all filters in box and not to insert TRX-DUO (or another SDR).
R.I.P. TRX-DUO
While i experimenting with i2c I killed something on this bus or i2c on FPGA itself…
Adding power/swr meter to the TRX-DUO transceiver — part.1 — code investigation.
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.
