New stuff arrived.

ts101, Owon hds2202s, antenna switch and a bit more

06.05.202319.05.2023 enthru hamradio sdr, trx-duo

R.I.P. TRX-DUO

While i experimenting with i2c I killed something on this bus or i2c on FPGA itself…

05.05.202312.04.2024 enthru hamradio amplifiers, hf, mrfx1k80

This month will be month of receiving cool packages, that is the first one :)

MRFX1k80HR5 transistor and ABLNO 96MHz clock

04.05.202308.02.2024 enthru hamradio sdr, software, trx-duo

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.

TRX-DUO based transceiver — pt.4 Software

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.

TRX-DUO based transceiver — pt.2 Filters and amplifier module

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