Geoff is right, you need more than just a position report, you have to do the calculations and provide a quick reference alert which the uniden would not do , also, it is a high power public frequency ( UHF CB ) long range device, more prone to jamming from whackers on the ground if they knew what is was. For cockpit displays I prefer an LCD with you in the middle, surrounded by targets within range and height labels.
Anything can be done - its just software. As for jamming, most 900 Mhz stuff uses spread spectrum techniques, this will reduce interference to a level and improve data throughput, also, the receiver is fairly deaf compared to systems that work long range, the likelihood of intermod , harmonics or sig gens interfering would be nil, the best source for interference would be a PDA or GPS inside the cockpit with harmonics generated from microcontroller clocks or VCO. Any system will have some problem we can all pick at, it really comes down to cost, overall reliability and need - I think we have all 3 in mind.

Subject: Re: Fw: [Aus-soaring] FLARM Mark It sounds like I'm working for Flarm ... which I am NOT. The big difference appears to be that the Flarm calculates the likelihood of converging tracks and alarms if this is the case ... then the unit will also locate the position of the other target to within 45 degrees or so as indicated by led's, and also a below and above led indication. It also appears that it provides a varying audible alarm controlled by proximity.
