Dale, it's good to see another Ham post to a thread like this one. KCØDJH here. I agree with what you say. We could go into the technicalities of Cell phone/ RC transmitter-receiver interference all day long.

The easist way that I have found to show people that cell phones do put out a strong initial pulse is to place a phone near a speaker. Paticularly a computer speaker which is supposed to be shielded. Usually, the speaker will hum when a phone receives or sends a call. However, the phone has to be within 12 inches or less in proximity to the speaker. It is possible that a phone could cause some level of interference, but it's highly unlikely. I still don't buy the "my cell phone reprogrammed my transmitter" line.

Rule of thumb, keep your phone away from your computer radio if you are concerned.
