Narrowband ka vs. superwide ka

**Stealth 795** · 07-30-2007, 08:32 PM

I think that rds should have a setting for ka narrow and ka wide.....
Reason being the narrow mode is more sensitive in any band .....
Wouldn't that make better longer ka detection ?
So what ka is used in us, and what is used overseas...And why ?

If I'm not mistaken that was sorta the "idea" behind usa mode on Some Bell products. It only focused on the specific frequencies that RD guns used and never scanned the entire superwise ka spectrum. It was also prone to missing out of tune ka guns but go figure.

Once again, I am not suggesting this was the same as narrowband ka. Narrowband Ka was just that, a narrower frequency than the modern ka of 33-36 (I know i'm not exact on this but just giving an approximation)

I am not sure that you understand the mode of band I am talking about..

Read:
When listening to a freq you use lets say, wide fm mode for your radio in your car...
Same with am radio and cb's all am(amplitude modulation)..
Is all the mode is doing is demodulating the transmission...
Like digital cable and such, we need a capable tuner to tune it in(digital)...

So what I wanted to ask the members is if we went to a more narrow mode on ka band, would we get better distance?
AND
What modulation does rd's use for ka?

I think you are confused, there is no modulation in radar detector :wink: You are only detecting the "raw" wave...

Yes, special "narrow Ka" features in detectors such as "USA Mode" in the RX-65 and "Euro Mode" in the V1 provide more sensitivity than if the detector was sweeping superwide Ka, and therefore more distance.

Police radar isn't modulated or encoded at all, it is unmodulated continuous wave.

Lol, i thought I might be correct but didn't want to make an ass of myself. Thanks for clarifying.
