My WebSDR on 2M Satellite and ISS frequency

I have disabled the 2M SDR until I can fix the adjacent channel interference.
I am only running the 40m SDR for now.

My WebSDR on 2M Satellite and ISS frequency seems to be stable with some adjacent channel interference.
I will try and make some change with a different antenna to reduce the interference.(Eggbeater antenna)
Here is the link
Here is also a very nice link to find out what is herd from a satellite point of view (live Sat DX spot)
