Frequency display accuracy?

o2bad455: If I understand what you are eluding to, you would also need a calibration certificate as to the accuracy of your STi.

Since the STi doesn't have any such certificates that are acceptable by law, nor is it considered an approved Law Enforcement instrument, you may wish to rethink your defense.

How accurate is it, such as for a Bel STi in tech mode? For example, if it displays 34.723 GHz, but the LEO produces a calibration certificate showing 34.665, how likely is it that the calibration certificate is for a different radar unit?

A very good point. I wonder if you can request that the officer, on the day of court, proves that his radar gun passes both its internal calibration test and displays accurate speed readings with its tuning forks, particularly in moving mode. The court likely would consider this to be a waste of its time, but maybe o2bad455 could demand this since his accuser is an electronic device which may be faulty?

I was on the freeway and ran across a CHP with C/O Ka band. I switched my rx-65 to tec display and it said it was 34.696 would this be a 34.7 radar gun?

Yes. It's 34.7 +/- about 50MHz(0.050 GHz). So anywhere between 34.650 & 34.750 GHz. CHP uses only Stalker 34.7 and laser. Same with 35.5 and 33.8 guns that I've seen, +/- about 50 MHz.

[o2bad455]

Agreed. +/- 50 MHz seems about right, although I think I saw one at -75 MHz (i.e., 34.62?) or so. I've also seen several Stalkers around 34.9 GHz, and one probable Stalker at 35.2 GHz (NYSP).

Yeah, the +/- 50 MHz is a general rule, not a strict rule. It's just what I've seen. There are some older Stalkers ATRs that are 34.9. I've never seen one myself, but they do exist. As for the 35.2 you saw, I have no idea what that is. I'd bet it was a false.

Thanks. You might lose that bet, though. See the Professor's post #7 in this thread: http://www.radardetector.net/forums/...-35-2-ghz.html
