Mr. Arnett. Yes, sir.
Mr. Griffin. Okay. Let me ask you this, this is your own private car?
Mr. Arnett. Yes, sir.
Mr. Griffin. Does the police radio broadcast over a frequency that can be heard on ordinary radio receivers?
Mr. Arnett. No, sir.
Mr. Griffin. What kind of special adaptation do you have to have on your receiver to pick this up?
Mr. Arnett. They call it a converter. It's hooked in with your radio.
Mr. Griffin. Is this an FM converter; do they broadcast on an FM frequency, do you know?
Mr. Arnett. Well, seems to me like it used to be AM and you could pick it up then by having your radio fixed a certain way, but they quit that. You couldn't do it no more, so you had to buy this converter to go with your radio to get it. And I listened to the move from the library over in Oak Cliff to the Texas Theater, and was listening to it when they got him, but I was at Grapevine.
Mr. Griffin. Did you hear the automobiles called in from the outlying districts over your radio, when you were listening to it; did you hear any communications from the dispatcher or otherwise, calling police cars in from the outlying districts?
