Various modes

S28

The Buzzer has used yet another frequency for its buzzing. In June we could hear the station on its usual frequency 4625 kHz and on parallel frequency 3842 kHz and this month it was on 4325 kHz for a couple of days. Rimantas reported this frequency on 22-9.

We have noticed more parallel frequencies in the past 7 years, like in April 2000 when it briefly used 4619 kHz. In January 2001 it was on 4635 kHz and in January 2002 you could hear it on 11600 kHz as well. The station suddenly appeared on 4632 kHz in April 2004.

XSL (Slot machine)

The Japanese Navy telemetry transmissions can be found on 4153, 4231.5, 4291, 6417, 6445, 8313, 8588 and 8703.5 kHz.

SK01 and variants

The Cuban DGI has again introduced two new modes. The new modes were identified as RDFT (Redundant Digital File Transfer) and HamDRM, an amateur version of the Digital Radio Mondial broadcast standard. Tom and Hugh were the first dxers who reported these modes. Thanks gentlemen!!!

RDFT can be decoded with DIGTRX 3.11. It requires Windows XP or Windows 2000. You can download a copy here: http://www.tima.com/~djones/digtrx3.htm

WinDRM decodes HamDRM and can be found on this website http://n1su.com/windrm/

Check the N&O website for sound samples of the new modes.
