Lilliput 664/w FPV Monitor Wireless Issues

Hi guys,

Not sure if anyone has one of these monitors on hand but a little bit of help with my investigative testing.

I recently purchased one of these monitors as it has an IPS display, relatively bright and good outdoor visibility, built in receiver and battery tray and no bluescreen.

I also have the AVL58 kit from DJI.

I specifically ordered the Lilliput unit that has the same frequency and channels as the AVL58 but alas it's not working to my satisfaction.

Channel to channel, the two devices don't seem to talk on the same channels but I've done some testing and have come up with the following frequency matching.



As you can see, the lilliput will receive on the corresponding AVL58 TX channels but with some noise. On the lilliput, I have an omni antenna since it has an SMA connector and I couldn't use the AVL58 CL Antenna with the receiver till I receive an rp-sma to sma converter.

Using the AVL58 receiver, channels match up perfectly. I'm trying to determine if it's at all possible to receive video signal on multiple channels that are completely different subfrequency of the 5.8ghz spectrum. Working with the seller to see if it's possible the factory might have sent me a wrong version.

Here's what the Lilliput has in terms of models.

CH1 CH2 CH3 CH4 CH5 CH6 CH7 CH8
A 5705 5685 5665 5645 5885 5905 5925 5945
B 5865 5845 5825 5805 5785 5765 5745 5725
C 5733 5752 5771 5790 5809 5828 5847 5866
D 5740 5760 5780 5800 5820 5840 5860 (FAT SHARK RECEIVER)

Here's what the AVL58 lists as frequencies.

CH1-CH8
 CH1:5705MHZ
 CH2:5685MHZ
 CH3:5665MHZ
 CH4:5645MHZ

 CH5:5885MHZ
 CH6:5905MHZ
 CH7:5925MHZ
 CH8:5945MHZ

Thanks guys.

Hi, have you found the solution for the problem? Can it be Lilliput monitor and not transmitter?

I have AVL58 set to channel 1 (5705) and 702 diversity monitor set to band A channel 1 (same 5705) and no problem with the video. I also had 701 (just sent it for repair) with the same setup and video was good. I haven't tried long range yet (200m max) but within this range video is flawless.
