vibrations on upper part of the video

[itayguy]

Hi, I have Duo 5800Ghz RX + immersionRC 600mw TX
but I don't get a clear nice pic like I get with me rangevideo 900 Mhz TX + RX

on the top of the screen I get these vibrations of the video, it doesn't matter what type of camera I use , I use lipo batteries to power the setup.

any Ideas?

thanks

I have a similar setup and have the same issue when going into a USB video capture device, and can't get it to sync at all into a ground station based OSD. I am suspicious of the RX (same issue with two TX and two cameras). Did you find a solution?

Thank you,
Andrew

I noticed that I only get this problem when it is connected via the video capture, but when I connect it to a TV screen , it works fine!

any how, It is annoying that there is no good support for this product - I would rather pay some more money to get a decent answers !

p.s. with my 900mhz from rangevideo , I don't have these problems

i get a perfect image on the fatshark dominators with built in 5.8ghz rx, but a separate rx connected to the japan dvr intermittently has this issue along the top of the screen. so (in my case) its an rx issue rather than a tx issue.

Hi ,plingboot I think that the reason that u get perfect image is because you don't use capture device, the fatshark is not a capture device , and that is why you don't have a problem , try connecting the RX directly to a TV screen, and tell us how it works.

I've also the duo5800 RX with 600mw tx and I've a similar problem in dominator googles or in a capture device.But if I replace the RX by a simple airwave RX, I've a perfect video.
Duo5800 RX is a v2. I find the quality of the video lower with the duo5800 RX than with a basic airwave RX. I've tested several antenna, several tx, several channels and each time the quality of the video is lower with the duo5800 RX.
Is it a bad series ?

I have the same exact issue ^ with my immersionrc 600mw 5.8Ghz tx and the new Uno RX. Haven't done any troubleshooting but I'm seeing a pattern here. I'll post my finding later.

The issue seems to be in relation between the tx AND the RX.
I've tried the DUO5800 with another 500mw Airwave TX and all is perfect (2 tests done with 2 differents Airwave 500mw RX).
I've tried the TX IRC 600mw with another RX Airwave (no diversity) and all is perfect.
Now if I try the TX 600mw with the DUO5800 i've the issue.

If you have access to a scope, check the shape of the vertical sync pulse and compare the performance with an old and new Rx.
