"K" IS LOCAL POLICE BAND, "KA" IS STATE TROOPER, AND "X" IS SILENT ELECTRONIC ALARM SYSTEMS. HAVEN'T FIGURED OUT WHAT "VA-2 ALERT" IS YET.

The units manual will explain what those are but "X" means a radar band and the number is the signal strength. Higher the number the stronger the signal. "K" is another band as well as Ka.

Dont know waht codes mean


By Codes do you mean the X, K and Ka signals that the unit is reporting? If so, those are the 3 bands used for police radar. X is the oldest and not used very much. K is also an older band. Ka however is the newer band and the most used for speed tracking.

Radar detector codes


When any detector "detects" radar, it will produce some form of Audiable sound. If someone is speeding, they need to slow down IMMEDIATELY if they want to avoid a ticket. It doesnt really matter if the radar gun is x, k, ka, ku, etc. You will probably get a ticket if you dont slow down.

Most dectectors will have indicators lights or displays that indicate the x, k, ka, etc., radar signals are actually being detected. This can provide SOME useful information. THe letters simply designate BANDS of frequencies that are used to send the radar beams. It is similar to changing the channel on a radio - k and ka bands use HIGHER frequencies for their radar signals.

X band is the oldest radar band and it is used for police radars AND door openers at supermarkets and other locations. If you drive by a supermarket, your radar detector is likely to go off and it is almost certainly going to be X band. CHeck it out next time you drive by a supermarket with an automatic door opener.

Since the police and the radar companies like to play cat and mouse, newer radar bands have been invented that OBSOLETE the older radar detectors. When the K bands showed up in the police radar guns, the radar detector folks had to have a new product offering that would detect X band and K band. And the race continues to go on even today and now, there are LASER police speed detectors and the new "RADAR" detectors now need LASER detectors as well. If you want to know the exact frequencies of these "bands" (K, Ka, etc), let me know and I will send them to you. But they are operating in the tens of GigaHertz regions.

What do the radar codes mean? X1,K1,K2 etc


Hi bb360 - X1, K1, K2 etc indicate the radar band the police are using and the signal strength you are receiving. For instance, if you were to see a X5 come up on your display it would mean the guy is right on top of you and it may be too late to slow down. In case you don't have a manual I've included a link for you. If this answers your question PLEASE rate this as fixed. If you need more help just add a comment and I'll be happy to assist you further. Thanks.

Radar codes


VG-2 is a technology that police use to detect radar detectors. Detectors with this feature will detect when VG-2 is in use, and alert you to its presence.

AND

the x,k,ka codes you see flashing are......

X, K, and Ka Superwide are the radar bands that are used by police radar guns. X band was the first band used for by radar guns, but is now the least used. All radar detectors that we carry detect all 3 of these bands.

quoted by a professional at the Cobra industries for radar detectors, cb radios and electronics galore.
