Hello,

Recently we are facing some problems with 433.
When we put 2 no XR5 on 433ah and put it under load, in CCQ section of link a big lost is shown and the link is gone out of stable mode.

We have done the following test on it without any success:
1- Testing many frq.
2- Testing out of a noisy environment
3- Updating OS and boot loader
4- Testing many different antennas
5- In bonding and nstreme dual the problem exist.

Is there any possibility that the Amper reaching to XR5 is too low?

Waiting for your kind advise.

Sure. What power supply are you feeding this with?

24v 0.8A

Should be OK (rb 4w + XR5 2x6w = 16w) since the PS only put out 19w your getting close to the limit. We have run this setup with out issues but prefer to use a beefier supply. One possible issue is low qaulity jumpers, they have been know to create interference Issues..... Does one card at a time work OK?

If it is power related, dropping tx power should help your CCQ.

I know in my system, two R52H running 5GHz interfere with each other in the same enclosure. They see -20dB signal. I have an XR5 running on an AP with an R52H feeding at at 5GHz and I don't have the same problems, though I have not done very thorough testing.
