MRF9180 HF amplifier.
Based on mr9120 aliexpress kit.
Stuff arrived
Plate for mrfx1k80, PTT sequencer and SWR bridge.
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…
This month will be month of receiving cool packages, that is the first one :)
MRFX1k80HR5 transistor and ABLNO 96MHz clock
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.
