Frank The ignition makes it through into your radio. It is most likely just one wire that makes the tick tick in your radio.
I learned that replacing / cleaning the spark plug connections will help a lot here. If you find burned contacts, you are close to the source. A new harness and plugs is most desirable in those cases, but also pricey. My Terra radio manual states that in some cases the noise can not be completely eliminated.

After the repairs to my alternator and magnetos, I have noise on my radio. I had the guy look for loose ground wires and antenna connections. He pulled the radios to check their connections. The problem persists. This time I tested the operation of my handheld radio and confirmed that the interference is on the handheld radio as well. When the engine is off, both radios work fine. The noise is a rythmic "static" that seems to have the cadence of the engine ticking over. It is not a whine that I have read is the sound of interference from an alternator. I have been told I need to find a "radio man" to fix my problem. Are there any other approaches that might be more direct rather than to continue to write checks to people who charge me for attempting to fix my problem without results? How about replacing the ignition wiring harness? Thanks. Frank Nelson N51DV - 415C TOA
