I have two gates, one on an earth-like planet and one in a station. The gate on the station works fine, but I'm having a weird issue with the one on the planet. When I placed the DHD, it made a buzzing sound and won't dial. I've tried removing and replacing both the gate and the DHD to no avail. I can see both gates in the quick-dial list for the gate on the station, but I can only see the station gate in the quick-dial list for the planet. The grid that the planetside gate is attached to is powered.
