Interesting Signals

M0TAZ

I snapped this in the 6 MHz range, can you help identify a few of the signals.

The signal at A I think is some propagation device?

B and C some form of digital data (STANAG)

D unknown

E SISTOR?

G? weak

I slow morse irregular poor sounding more like a beacon ?

J STANAG

F and H are SMPS but added letters to be clear.

This helps quite a bit: https://www.sigidwiki.com/wiki/Signal_Identification_Guide From our friends at http://rtl-sdr.com

A: JORN, Over-the-horizon-radar (OTHR) from Australia. Note the short intro tone in the middle of the passband. This distinguishes it from similar sounding signals like (for me) the Tiger radars of the SuperDARN network etc.

E, G: FSK/RTTY

Would need to hear it or see zoomed in. But you're probably right.

Others: Correct I believe. The best blog I know discussing HF digital modes: http://i56578-swl.blogspot.com

Thanks, John, that's great I will have a read.

Interesting to see thats OTHR from Australia, will take a closer look. The SDR has renewed my interest in SWL, and its great fun trying to identify and catalogue the many signals.
