There was no band in the vicinity,
but the music was plainly heard by
two other persons helping soap. II

transmitting Radiophone station was
using, so that the strains of the con-

complicated apparatus necessary at
the usual station. The case is an

AZ. Since you do not state what
the angle is. in the statement mot
quit parallel it is difficult to give the
effect. No doubt you will get buzzing
sound in the receivers which can be
probably tuned out by the variable
condenser.
As. Single wire rs feet long will
give the best results for receiving.

@ Will you please tell me if it
IS suitable to use a simple antenna
made up of single bare or insulated
copper wire, running around the
room, in back of picture moulding?
Both ends of the loop 80 formed are
connected to a lead wire. VIII suit

an antenna when a crystal detector
IS used?
A. This type of aerial will work,
but do no: connect both ends OF the
loop to a lead wire. y Just connect
enc end of the loop to the instru--
ment and leave the other end free
You can get some results with
crystal detector, but don't expect too
much.
