    The repeater filters out that garbage anyway. :p

    QST test results were the same.... Baofeng is a dirty radio.

    You mean, the particular radio they tested?

    I'm getting a different story here:

    https://mikebeach.org/2015/11/16/arrl-baofeng-testing-revisited/

    This is what the author says: " but testing at the informal environment of a convention could lead to simple mistakes in the test setup. "

    and

    "It’s also important to note that the ARRL clearly mentions in their article that this testing was performed on used equipment, not newly-manufactured units "

    So, dirty Baofeng, or dirty ARRL or a bamboozled public/ham community? Who is pulling the 'fast one' here? Seems many folks are unaware of some specifics on this issue ...

    Their test configuration looks suspect at the convention looks suspect too. No HP filter used ...

    Reopen:


    I hate to reopen this post, but at first I said the radio flunked. Then corrected and I reread the FCC rules spelling out that 30 to 225 mhz, 25 watts or less, the unit under test must be 40 db down or better. Based on that statement, the HT passes.

    Enter January 2020 QST article on page 60. The bottom left corner clearly reads the above statement......40 db down.

    BUT, they use 53 db down in their tests. Using that as a benchmark, these units flunk. Under, "Testing" on page 61, they clearly state 53 db as their benchmark !

    So now my question is, "how do they come up with 53 db instead of 40 db?"

    What am I missing? I am not questioning how they performed the test but why 53 db? So do these units pass for fail?

    The difference in db and dB. :D:p

    They pass only using the provided antenna.
