Have you set a filter, such as height or range?

Any unusual atmospheric conditions? Is the Antenna connected fully?

There are some very strange conditions at the moment causing a lot of noise on the band. This is bad news for Mode S watchers and good news for Radio hams. I have been working Europe on low power on UHF & SHF the past few days.
I am trying to upload some pictures with and without preamp but it keeps timing out on the upload. I will try again tomorrow
