Hi guys,
Been having a peculiar problem. Setup consists of 2 868 Radiotronix modems. The downlink works fine, but uplink refuses to work! The antenna on the plane is a simple monopole antenna ( has worked great in the past on this modem ), and the ground setup is a patch antenna. The funny thing is that it almost looks like a range issue. On the ground, with the plane nearby, uplink works, I can move waypoints etc, but even 200mt's above, in the air, uplink refuses to work! I tried decreasing the number of downlink messages, but that did not help. I've never had problems with these modems in the past. Anyone know whats happening?
All inputs appreciated!
-Thanks
Uttam
