I am using RedPitaya SDR + hpsdr2alsa + websdr. When I start hpsdr2alsa with command:
/usr/local/bin/hpsdr2alsa --interface=ens16 --samplerate=192000 --adrx1=160out --frx1=1891000 --adrx2=80out --frx2=3591000 --adrx3=81out --frx3=3783000 --adrx4=60out --frx4=5341000 --adrx5=40out --frx5=7091000 --adrx6=30out --frx6=10191000 --adrx7=20out --frx7=14091000 --adrx8=21out --frx8=14283000 --nRX=8

then the last (adrx8) is not on the right frequency 14283000.
All other ones 1-7 are working Ok

Some more details: I have "Red Pitaya STEMlab 125-14" and I use the "SDR receiver compatible with HPSDR" software from http://pavel-demin.github.io/red-pitaya-notes/sdr-receiver-hpsdr/

if I change --frx8=14283000 to --frx8=1428300 or --frx8=142830 or --frx8=14283

Nothing happens. The last 8'th tuner does not tune to the correct frequency...

Hello,
I never try with 8 receivers and i pretty sure that not run properly because it's based on gr-hpsdr library that implement only 7 receivers.
8 receivers protocol it's not standard. Maybe you can contact the gr-hpsdr autor (https://github.com/Tom-McDermott/gr-hpsdr) for ask about this modification.

Sorry about that.
