    Hi all,

    I have been doing some testing with TMF2 and noticed when it is on that I could acquire a speed on K band and go back to hold without even being detected.

    Have others experienced this or do I have an odd acting unit.

    My theory it is that the delay is induced by TMF2 needing more samples to assess the threat as BSM/speed info before alerting.

    Just want to make sure my findings align

    Ah, okay! I must have missed that... So if your locale uses QT then you have to live with the falses?

    IIRC, TMF2 imparts about a 0.5 second delay on K band.

    If you are somewhere that routinely uses <0.5s QT K band, move.

    My K gun isn't anything fancy, but it's super accurate(when compared to mdr ii side by side to mdr ii) i believe it's made by USA radar (I think the model is phantom patrol)

    I have my v1 connected to a benchtop power supply on the other side of the room. About 30-40 ft?

    Is the gun using FMCW radar? If yes, TMF2 may be filtering it out.

    If it's left on longer than(what feels like) a second, my RD will pick it up.

    Speed can be acquired with quick trigger and the RD never sees it

    It would never hold up in court. Not in Florida at least.

    Any why is that? Is there a min time they have to track you on the gun for it to be admissible? Not sure saying my RD did not pick it up or it only alerted for X amount of time would help much in court, ha. I truly do want to know if there are hidden laws or regs about this!

    Please. “I observed the subject moving at what appeared to be high speed, approximately XX miles per hour. My radar equipment confirmed he was going exactly XY miles per hour.”

    Never hold up in Court?? I'm not sure what courts you have in your parts, but around here, the Cop can say whatever the heck he wants and the judge will take that as gospel. Unless of course you have some kind of proof otherwise, like Cam footage with GPS speed on the footer at the same time.
