Hi Forum, I built the Zenith transmitter a while back and want to connect my iPhone to it, my concern is to keep any B+ from getting into the phone. I thought of using a blocking capacitor to prevent DC from entering the output circuit of the iPhone.

Any ideas would be appreciated.
Tony

Yes use a 100n capacitor in series. I use my iPhone to feed ky homemade FMTX all the time.
