Guys, I'm kinda worried. I'm not getting more than a few meters of useful range with a FS832+Blackpearl in urban environment. I'm on a stock setup, standard antennas (I'm in Colombia, fancy stuff like antennas are hard to come by), channel 32. Clear picture standing next to the copter, degrades rapidly to nothing within a few meters. PAL-PAL, frequency match, diversity mode on the monitor. What am I missing ?
