Beeping morse-like signal at 299,995MHz found in Lisbon, Portugal. Using stock antenna from RTL820T2 RTL dongle and SDR#. The frequency of the signal oscillates slowly as if moving. Permanent signal 24/7. Tried Cwget, TrueTTY, SeaTTY in various modes but I could get no meaningful result. I'd say military, any thoughts?

P.S.: title says 599MHz, that was before I found it to be a 2nd harmonic.
