	<span style="line-height:1.5;">After nearly a year of
probation, the type of AM
radio repeater circuit in general can be retrieved in a number of local radio
stations; the
installation is convenient, the output has a loud voice, and bass is rich, which make it indeed
a good choice for beginners¡¯
homemade radio circuit. Beginners
can give radio principle about double harvest theory and practice. The whole
circuit fabrication costs low. The AM circuit is</span><span style="line-height:1.5;"> successful, plus USB, TF playing blocks, FM module circuit without external
antenna, and the antenna is surrounded by a large box inside a circle around
the wire. The
two buttons use to control move, and
changing
frequencies is very convenient. We
usually put the electromagnetic spider web test on the radio and put it all
over the country.</span>
