I am beginning to wonder if there ever really was any 33.8 issue with the STi, or if any bug has already been fixed in the current A4M9 firmware version which has been out for quite a while. In the GOL test, the STi never tested anywhere close to being virtually dead on 33.8 although the best run against the 33.8 gun had significantly greater range than the other runs. This makes me strongly suspect some type of RF interference from other electronic devices which were used during the tests such as cell phones, two-way radios or possibly other radar detectors in the same vehicle.
Also, the "other guy" who we don't mention did a comparison test strictly between the STi and the V1 in December 2006. The STi performed splendidly on all Ka bands during the test.
There are also a couple of threads posted here where a STi owner said that his STi appeared to be virtually dead on 33.8, or that his STi suddenly started detecting 33.8 just fine after power cycling the unit. I've got to discount these particular posts since nobody else has experienced similar results with their STi, and GOL never had either of the two STi's they were testing come anywhere close to going virtually dead on 33.8 Ka.
A recent post and response from another thread:
Did Carl Fors test the STi? Looking forward to more conclusive results either way.Let's look at the Professor's explanation for the "33.8 bug":Originally Posted by radarroy
The Professor mentions that when a brief "blip" is detected from a sweeping oscillator, that the STi either raises its detection threshold or ignores a section of Ka band for a certain duration in order to prevent a false Ka alert from a leaky radar detector. This sounds like a hypotheses rather than a working theory.Originally Posted by jimbonzzz
Indeed, I recently had Azonehits perform a specific test:
You could cover a piece of cardboard with metal foil duct tape and then cut out a small elliptical aperture such that the ellipse will appear to a be a round hole when the cardboard is oriented at a 45 degree angle. Thus, most of the radar gun's output would be reflected straight up towards the sky, yet a small amount will pass through the hole straight towards the radar detector. In this way, you could easily setup a test which you could perform in your back yard since most of the Ka gun's radar will be reflected straight up. I have a feeling that the STi will perform far better when it is looking at the circularly polarized radar passing through the hole. Then you can try to duplicate the 33.8 lockout bug when another radar detector is powered up close to the STi.
He did this test (with the radar gun pointing straight up rather than through a hole as I suggested) and then repeated it with an X50 powered up right next to the STi. Here is what he found:
I think that Azone's test results conclusively show that there is no obvious 33.8 bug -- at least with the current A4M9 firmware version of the STi which has now been in the field for a while. It is possible that the A4M9 firmware may still show a very slight reduction in 33.8 Ka range if another strongly polluting radar detector is nearby, but I think that any original 33.8 bug has already been quite nicely resolved in the A4M9 filtering code.Originally Posted by Azonehits
This is my consensus, for what its worth! What do you all think?
