True 5 miles Is possible with around 90mw I think the ARF is capable of. What we need is a Rock Solid signal even when theres line of sight issues cockpit positioning etc.
Theres only a 25khz section of the band that permits 500mw can someone confirm the ARF is transmiting in that section.
Given 400+ mw and a half decent antenna that negates the need for decent ground planes unless you have a metal aircraft and want to start cutting holes in it... (not forgetting Mod Status) I believe 5miles minimum certainty contact is achievable.
Assuming licence restrictions are OK we need a bolt on narrow band amplifier accepting the input of the ARF module or even the XRF which would be cheaper. Shouldnt be too difficult I wouldn't have thought except for cooling issues if running a continuous amp.
Another thought is how good is the ARF receiver would a decent antenna and a preamp work or would we swamp the ARF RX.
Light bulb has just gone off..... must contact a friend who used to work in this field designing kit for the mobile phone network and P2P communication systems....
