Replied to the thread DXPatrol Upconverter Power adjustment.PostHello Thorsten,
I am not familiar with the DX-Patrol up-converter but I assume that it is working as a linear converter. So what you would need is a relatively cheap step attenuator on thw input side of the converter to reduce the output power. This… -

Liked IZ7PDX’s post in the thread Software DVB-S demodulator.Like (Post)Well done Marcel, I managed to decode my signal transmitted with the second Pluto up to 4250 MHz! Very little is needed to reach 5800 MHz. With this version over 4250 MHz the waterfall does not display signals and it is not possible to decode. I attach… -

Liked HB9SKA’s post in the thread 10GHz Attenuation by Heavy Rain.Like (Post)My intention to ask was to learn, if a wet LNB has an influence to the attenuation. If yes, then you can't measure it alone for heavy rain. But Geri answered my question. -
