Listened to it 3 times and made no sense out of it. Maybe 4 th time. Dought it. Glass of wine and grouper cheeks. Then watch it. Like having to be a NASA engineer. Still no sence why I got a ticket.
Think of it like FM radio. The band goes from 88 - 108, with each station selecting a specific operating freq. (like 98.5). Radar guns are the same, with each manufacturer selecting the specific freq's they set their guns to. Individual guns can 'drift' from their target range for a number of reasons, so a gun spec'ed for 98.5 could actually be operating at 98.4 or 98.6 etc. And some can get really out of wack and be way off (old guns or cheap/lazy agencies that do not do reg maint/tuning on their equipment).
Some specific ranges along the 'dial' perform better than others, so manf's tend to set in those ranges. Detector co's have segmented the specific ranges used by the various known gun makers into bands (2, 3, 8 etc.).
Here's how the Ka bands by state (generally speaking) break down & the freq ranges in each band:
Note that CA has band 11 which EU also uses. That is considered Ka2 or Ku or Ka ultra depending on who you are talking to.
You may have been nabbed if they are fooling around 'testing' some new gun in the Ku band or their Ka gun was WAY out of wack or your countermeasures are not working properly.
I would get a traffic lawyer and have him demand the last certification/tuning certificate for the gun in use by that cop on that day.
As for your detector settings of Ka wide / default / Ka narrow, you need to look up the owners manual to see what they are really scanning for as it can vary by manufacturer.
In general tho:
Ka wide would mean the entire Ka range 33.4 - 36.0 (slowest, more falses but safest)
default is probably Ka wide
Ka narrow scans segments 2/5/8 +/- 100 to 120 MHz (fastest, fewer falses, but can leave you exposed to guns way out of wack)
Again, your specific device may vary slightly in the specific numbers and +/- varances !
All this info applies to K band as well (it's just a lower freq band range from Ka).
X band is outdated and rarely used anywhere except for auto door openners, security systems etc. and can be safely turned off in 99.9% of the US.
