Question
Stupid question (low pass filter)

I recently upgraded from 2.4ghz to UHF for control but still have a low pass filter on my 1.3ghz video Tx. My understanding is that I should no longer need the filter because UHF is at a lower frequency than my video Tx (1.3ghz). Is this correct? Can I remove my low pass filter now?

If you're using any type of GPS device (OSD etc.) then keep using the low pass.

I'm using a DOSD with GPS as well. I was thinking about setting up another system and using my current low pass filter but now I may just keep it and get a new one for the other system. Thanks

Why not just try without the filter first to see if it reduces your GPS sensitivity. I don't use a filter & have no GPS problems with 1.3.
