Today was the first time I'd really hit any kind of Ka with the 9930. State Police run Stalker Duals (34.7, right?) around here but usually they are the I/O masters (or just don't care). Only two times before today had I ever encountered them running C/O. Well, just as I pulled out of work there was one passing right in front of me. Sure enough "Ka1" lights up. A panicked motorist in front of me kept the trooper within maybe 1/4 mile the whole way. I'd have "Ka1" most of the time with sporadic quick jumps up to "Ka5."
I don't know if he had the rear gun running or if I was picking up the front. If it WAS the front I'd be amazed since I was behind him. Even if it was the rear, I'd at least be surprised the Cobra works on Ka.
