Modification microphone original icom ic-7000
Often heard about the problem of low modulation in the c-7000. But this is a solution. It is installed inside the original
hand microphone preamplifier circuit as well as changing the capsule for a higher quality in order to obtain a better
response audio.
He then detailed the steps in a series of photographs:
Here we see the point where insert preamplifier must
withdraw the SMD capacitor brown we see at this point. The
yellow wire represents the output of the preamplifier and
the entry is the white.
This is the preamplifier to install inside the
original microphone.
At this point we will take tension power necessary for the
preamplifier.
And here the point with the ground, the reference for the
both dc power and the BF.
