Anyone else hear it?....what is it?

IKY in CW repeating over and over at 1804 UTC

It is a NDB (Non Directional Beacon) for air and maritime navigation

Non Directional Beacons. These are transmitters that in practically all
cases only transmit an ID in morse code, consisting of 1, 2 or 3 characters.
Since the signal is transmitted in slow morse code, it doesn't require too
much time to learn to decipher these IDs.
These beacons are intended for (both civil and military) air and maritime
navigation. By tuning into two different beacons by means of antennas with
directional sensitivity it is possible to determine ones exact position. The
exact locations of the beacons are known and thanks to their ID (and the
format of this ID) they can be easily identified. Each NDB has its own
format. One may transmit 1 ID, followed by a 3-seconds' gap (pause), another
ID and 3-seconds' gap, etc; another one can transmit 2 IDs, followed by a
17-seconds' tone and then repeat the whole procedure; some may also transmit
1 ID, followed by a 3-seconds' gap and an 8-seconds' tone, etc.

Since these signals are mainly intended for airplanes and ships at not too
great distances, they don't need much transmitting power, which makes them
especially attractive for DX-ers, because in spite of their reduced power,
very often distances of over 2,000 or even more kilometers can be bridged.
They concentrate mainly on low frequencies (I suppose because of the
reliability of reception on these frequencies) below the Medium Wave band,
although there are also NDBs in the actual Medium Wave band. For use in
Europe the range between approx. 250 and 520 kHz is used, but there are also
beacons on lower frequencies (the Long Wave band is not being used for
broadcasting in the Americas).
