    ALP Power - Blue and Green?

    Update - it appears that the "Mute radio during radar alerts" config setting might govern the relay trigger wire as well as the mute wire. I did not have this active.

    ALP Power - Blue and Green?

    (Reviving an old thread...) Under what circumstances does the HW4 ALP CPU trigger these wires? I see a constant ground on the green wire and a constant +5V (I think - reads as HIGH on an Arduino) on the blue wire. This is during several k-band alerts from NetRadar DSP front and back. No...

    Excessive K band falsing on NR-DSP

    Reminds me of a plant operated by a former employer many years ago. They blew up a reactor when a flame propagated back from an ignition source in the vent line. There was a pressure sensor and flame extinguisher system in the line, but it had been turned off. Why? It kept tripping. False...

    ALP Jamming problems. Works then don't.

    Are there many reflective road signs facing you as you drive your test route?

    What is your level of confidence in RDFGS?

    Ready access to bad data will only lead people astray, in my opinion... But good display of good data is gold!

    Excessive K band falsing on NR-DSP

    Oh no! You only have 15 (IIRC) ARF slots, before they start to overwrite from the beginning. There's no benefit to having duplicates! Also (and I wish I had done this) - maybe write down what you have saved already... 1618772733 Although now that I think about it, if you set an ARF and again...

    External LED Fix

    I know this is an old thread, but I've just been looking at my LED and since the forum is searchable... Common cathode. Max voltage appears to be 3.3V from ALP CPU.

    Excessive K band falsing on NR-DSP

    The Twin Cities metro area is an island of Ka-only (with increasing lidar as well). Not that you’d be likely to drive here... 😜

    Excessive K band falsing on NR-DSP

    It's not exactly a heat map, but check out the RDFGS subforum. A better bet, if you know where you'll be traveling, would be to just ask in the Road Trips forum and in the appropriate regional subforum. You'll get anecdotal, but current, information.

    Excessive K band falsing on NR-DSP

    EXCELLENT point about ARF blocking only weaker BSM-level signals. Wouldn't it be great to be able to see the ARFs you have already set? I wish I could see mine. 1618750520 If you're in a metro area where K band is not used, it's a BSM or stationary false :p Seriously though, that's kind of...

    Excessive K band falsing on NR-DSP

    I can only speculate. The common ones are known. Manufacturers probably contract with vendors to provide a system for them, and have it tweaked to their specifications - kind of like the all-wheel drive systems that Haldex provides to various automakers. A Haldex system in an Audi will be...

    Excessive K band falsing on NR-DSP

    I went through your data - thanks for posting those screenshots, by the way! There were 9 distinct data sets (looks like screenshots 5 and 6 are duplicates). By my count, here's how the alerts broke down: Alert Type Number % of K Total K3 (24.165-24.180) 39 42% K5 (24.195-24.205) 36 39%...

    Excessive K band falsing on NR-DSP

    OK, here's the original thread where Tom announced ARF on HW4 CPUs. It was over in the ALP subforum. There's another thread dedicated to ARF here. For some historical perspective, here's some discussion around why the NetRadar K-band segments were set up the way they are today.

    Excessive K band falsing on NR-DSP

    The NR-DSP can be made quite quiet on K band, but you have to do a little configuration work to get there. The band segmentation was revised to allow you to slice out the common Honda/Acura (24.200, plus or minus) and GM (24.167, plus or minus) bands. Might have the car makes mixed up, but you...
