Dear LFers,

if you have run out of LF signals and still want a weak signal
challenge, I have put a temporary DFCW beacon on 80m.

Details:

Format: DFCW10, 2Hz shift
Dit frequency: 3500,000.993 Hz (say 3,500,001 Hz...)
Dah frequency: 3500,003.004 Hz (say 3,500,003 Hz...)
Power: +2dBm output (1.6 mW)
Antenna: Dipole, 10m up
Message: SM6LKM <5-character codeword>

The frequency is GPS disciplined and should be accurate to
1e-10 or better. The DFCW timing, however, is controlled by
a PIC processor clocked by a simple piece of rock.

Reports are welcome!
