Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

In my first fpv flight I got some interference (black lines)

My video is:

Setup: 1280mhz, 700mw output power tx with 1/4 lambda monopole homemade and stock rx antenna.

r/c 35mhz ff7, rp8d1 rx

Any idea of what may be causing this?

Thanks

Seems a bit worse when you're close in - not so much interference on the picture, rather intermittant loss of frames. It looks like my original setup. I'd put my $$ on multipath interference (the direct signal is interfered with by a reflection 180 degrees (half a wavelength) out of phase), which unfortunately isn't made better by more power.

You could buy or borrow a diversity setup and try two receiver aerials separated in space; I found this sort of problem largely eliminated by my Oracle diversity. You could also try lowering the video transmit power, as that might help a bit.
