Mike B's Sensitity Testing Part II HERE!

[aust3333]

Wonder too. Ive said it 3 times already but no one seems to care what or if there would be a difference. If i had an RX-65 i would def sed it in, to get it tested in USA mode!

There is an RX65 on its way.

2 if aust3333 is sending his. I sent mine in on friday. should be at michael B tuesday or wenesday.

RX65 in USA mode is only 1db more sensitive then Intl mode for Ka only.

X and K are unchanged.

The current software includes 34.3 coverage for the USA mode.

Coverage is 33.7-33.9 / 34.2-34.4 / 34.6-34.9 / 35.4-35.7 on a 6.2 unit.

Why would you run USA mode and chance not responding to out of tune radar?

If you are receiving excessive falsing from radar detectors that show up as 33.4-33.7 / 33.9-34.2 / 34.4-34.6 / 34.9-35.4 / and 35.7-36.0 on the display, you may wish to consider the USA mode however if you do not received falsing within these ranges, you are risking a NO RESPONSE to radar that may be outside the USA windows just to get 1 additional db for the 33.8 / 34.3 / 34.7 / and 35.5 frequencies.

Thanks michael b. Very good info.

If the radar was that out of tune, wouldn't the speed reading be wrong anyway?

It would have to be WAY out of tune to have much of an effect on the speed reading. Even if it's out by a few hundred MHz the speed reading will only be off by around 1%, or 1 MPH @ 100 MPH. Extreme case: if a radar unit were to drift from 33.4 GHz all the way to 36 GHz, the speed reading would be off by around 7%.

[ES13Raven]

Aren't all officers required to calibrate their radar guns often?

I think the chance that you would run into a radar unit that far out of tune that USA mode would miss it, is very small. I think the benefits outweigh the risk. :wink:

My reasoning used to be that "the K-Band bandpass is only 200 MHz wide normally, and nobody seems to be worried about missing out of tune K-Band radar". But that was before I knew about the 34.94 Stalkers...

Honestly, how common are they? There weren't many sold right?

Hard to say.... best info available suggests that 1000+ were sold.
