Title: Frequency offset
Post by: ihweb on Jan 13, 2025, 08:24 AM
Hello friends.
ThantomSDR is so useful.
But my RX888 still has a 1K frequency offset, can the config set the offset correction? thanks .

Hi,

in config-rx888mk2.toml

line frequency=0 # Baseband frequency

I would try putting -1000 or 1000 instead of 0. I haven't tried it, my 888 works fine.
Nothing can go wrong and it might help.

Good luck!

Post your start-command and toml-file, else it's impossible to see what goes wrong.

Thank you for your reply. It is this parameter that can correct the frequency. Thank you.

It should not be off that much.

Typical they are spot on freq.

Why do you think the freq is off on the RX888?
