I turned onto a street today that has a known K-band speed sign that I drive by every day and have locked out on my 9500i. Both of my RD's go nuts(normal for the SRX). I look down at my SRX display and it shows K 24.153. That's unusual, because that sign is normally about 24.190. My first thought is "COP!". Then I look up at my 9500i and it shows 2 signals, 1 weak X and 1 strong K. So, the sign has changed frequency since last night. Maybe someone calibrated it or changed it out for some reason, I don't know. But anyhow, the 9500i reacted as I would hope it would if it detects a different frequency than the one(in this case 2) it has locked out.
Good job 9500i!
But now, I have no way to unlock the old locked out frequency. Hmmmm.
