Thanks very much.
Did read about that shouting distance, of course, it is stated often in the GG -- I just can't believe my radios are malfunctioning that often!

It's not just malfunctioning radio's but also failures to connect that are modelled. Remember that sub-unit leaders especially usually have to keep track of several radio nets at the same time (within their own unit/vehicle, with his subordinate units/vehicles, with his commander, and with other supporting formations (think a mech platoon and a tank platoon operating together so their commanders have to keep in touch) and possible coordinate artillery or air strikes, etc).
That means a commander may be otherwise engaged and temporarily out of contact with one or more of his subunits.
