The use of 121.5 in the UK for "practice pans" and "random chat" is distracting and does, in my experience, lead to guys continously turning down the volume or de-selecting the frequency. How feasible is it to have a "sim-guard" frequency to be used (with D and D) for Practice Emergency calls?
Also, are there any radio fits that allow simultaneous monitoring of the active ATC frequency and VHF guard on the same box? Most military UHF boxes have this facility for listening to 243MHz.
