Continue working on SDR Box

Some improvements.

Now i think it’s better to insert all filters in box and not to insert TRX-DUO (or another SDR).

Homemade SDR Transceivers based on demo or datasheet modules.

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.

As i don’t have any windows machines at now, looks like the best software for me (that is working on arm and intel macs) is linhpsdr.

Some pictures of boards in the case and a few words about power supply.

To get working device faster i decided to just buy prebuilt modules from 60dbmco.

This post is about trx-duo board itself.
