The decoder output section.

The lower left portion of the program is where decoded sequences display. In the display

above you can see a number of receptions. Along with the decoded text is information about

strength, time offset, frequency offset and an indicator of the error correction method used to

decode the signal.

UTC – Period signal was received.

Sync – A measure of strength of the synchronizing tones. Higher is better.

dB - The strength of the received signal in dB. Higher is better. 0 is the upper limit.

DT – The calculated offset of the received signal from your local clock. Values of .1 to .3 is

typical.

DF – Offset in Hz from the center point (0).

B/K – Error correction algorithm used to validate the reception.

B = BM (Simple Reed Solomon algorithm, open source implementation)
