Hi,
I have just recently modified a small FM transmitter which I have built to hold an external microphone, the system does work, but when I hold the external mic away from the transmitter, sometimes, the reciever starts emitting a high frequency feedback like sound, but if I touch the mic, or even bring my hand near, or hold it up to the transmitter it goes away, the internal mick(Half in the baox I.E) does not have any problem, presumably because it is near the transmitter circuit, also sometims holding the mick away from the transmitter a little farther stops it, neither mics have any shielding, can anyone help me with this?
Thanks, SlicRic
