In order of importance to assist in IDing a signal: recording (audio or I/Q), screen shot of spectrogram (such as using SpectraVue, Spectrum Lab, or Spectrogram 16, but anything that will show a waterfall will help), date, time, frequency, and mode of operation. Aproximate location you heard it from, and by this I mean the location of the receiver, just in case you are using a remote.
From your description it is impossible to say what you might have heard. For example, right now locally (west coast) I hear the edge of a North Korean jammer on 6335 kHz USB, but if I go to an east cost remote I have off tuned STANAG 4285 and no sign of the jammer, and when I go to an MA remote I see nothing on that freq at all.
Not trying to be snarky or anything, just saying that the more data you provide the more likely you are to get a meaningful answer.
