Such devices do exist in real life, and they are very rare even in the military. I encountered them while serving with a USASOC unit. They transmit and receive radio signals(which are encoded) on UHF/VHF. Multiple devices with the same encoding can, over a 5-15 mile radius(terrain dependent), detect the distance and direction to eachother. While these would be extremely useful and be a heavily desired item for team players. Their rarity, to simulate a real world environment, would need to be like a .01% drop rate. If that even. Another thing is that I can see it being difficult to create such an in-game item. My counter proposal is that we insert the military, Sincgars radio system, this is widely used and in just about every HMMWV in existence. So that solves the drop location issue, just have the burnt up HMMWV's have like a 10% drop rate of a useful radio. Due to size however I could see this taking up a large amount of space, but not more than four slots in a backpack, the new model that came out a few years ago is smaller. Also having a Handset or headset drop from the soldier Zeds would seem appropriate. My thinking here is a radio that would need 2-4 slots of pack space, the compatible hand/head set taking a slot in the toolbelt. The sincgars operates on splits of 25kHz in a range from 30.000-87.975, (every .025 would be a channel) so it would need to be programable (maybe thru the map display as the watch and GPS are) but at the same time, the odds of someone finding youre channel are very slim(IRL it is near impossible once encoding or channel hopping is loaded/enabled) The newer models also have data transmitting ability which, when linked with a milgps module, can tell others on the same freq your gps info and load it as a waypoint in their milgps(if you have one connected). I am probably proposing to much realism for such an ingame item to be enjoyable, but that is what ya get from a veteran I suppose.
