    I ve been hearing this signal her in NE PA. Its centered on 3.528 but its pretty wide..from 3.524 to 3.532 . Its 7 short blips then 1 longer one and then resets.

    Ok ; I found an audio clip while searching all the RFI sites. It turns out that it is a LINK 11 (C.L.E.W.) also known as ALLIGATOR and is used by NATO and US Military for maritime tactical stuff.

    Here is a link with sound sample https://www.sigidwiki.com/wiki/Link-11

    No one else hears this on 3.525 tonite?

    I don't hear the signal tonite in Maryland, neither last night two hours after your post.

    Normally there is a Link-11 net just above the 80m band. The navy is normally not a trespasser on 80m.

    Perhaps it is a low power signal in your region from perhaps Portsmouth NH or the naval base in Maine. Could be an error in frequency that has gone unnoticed.

    Update:
    I was able to hear the signal on 3528 LSB on a WebSDR site in Milford PA by K3FEF. QSB from very weak to moderately strong.

    Most of the other Atlantic WebSDR stations don't cover that frequency.

    Nice work! Thank you. Milford is 50 miles east of my QTH. The signal was peaking at S4-5 last night. This is interesting . Thanks for the help.
