Hearing Female voice,AM Mode,10345KHZ...First numbers sta Ive logged..
Im in the city,,lotta RF interference..But im Hearing her..some fade out..Using SDR# and the Ham It Up converter..and a UHF/VHF Discone..

first 4 numbers are 5584..shes been leading with,,then 1184.....uno uno ocho quattro...Mostly 4 and 5 number sets...


Question,Theres a digital noise thats TXd between the numbers readings,,what is the mode?...can it be decoded?..

 

[poltergeisty]

It could be RDFT or BPSK 31.

Edit- Well lookie here http://swling.com/blog/2013/02/how-to-decode-that-rdft-in-numbers-station-hm01-roland-explains/

RDFT by the way stands for Redundant Digital File Transfer and is used in HF digital SSTV.

HM01 always uses 5 figure groups, never 4 figure.

As the links provided tell you, the data can be demodulated using DIGTRX. However, that does not make them decoded. The resulting data files are still encrypted.
