Why telephone rather than radio? Radio let everybody know what is

Likely mandatory when there is some other activity in parallel (aero
tow, power flying ...).

Nothing worse than someone else interfering during the critical phase
of a winch launch (initial acceleration).


A worse thing would be someone interfering not to the communication but
to the launch itself because he is not aware of the launch. Of course
this is a discipline that everybody has to observe, i.e. don't use
the radio for anything else when a winch launch is in progress. This
also implies that every glider or tow plane has a working radio, which
is the case by us.
