Homemade SDR Transceivers

Homemade SDR Transceivers based on demo or datasheet modules.

BFG591 as driver.

08.05.202315.05.2023 enthru hamradio amplifiers, hf, mrf9180

MRF9180 HF amplifier.

Based on mr9120 aliexpress kit.

Stuff arrived

Plate for mrfx1k80, PTT sequencer and SWR bridge.

06.05.202320.12.2023 enthru hamradio gadgets

New stuff arrived.

ts101, Owon hds2202s, antenna switch and a bit more

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.

Old tube stuff I was using.
