The "waterfall"

i am on 14.0701 watching the waterfall, with Digipan, there are some signals wider than others. Sometime I suspect that that signal may be BPS63, QPS31, FSK31, or Pactor. I keep it on usb like the setup instructions say. Is there any way to tell what protocall is being transmitted? Also some of the calls I lookup come up not found on the ARRL FCC ID page. Is there an international lookup page I may be unaware of?
 

some software does ID the mode, other don't. I don't use Digipan so I don't know about it.

can you change the mode using digipan?


also try the call lookup function on QRZ or on this site;)
 
31 is almost same for BPSK & QPSK, 63 is roughly twice as wide and then 125 wider than that. If you turn on your monitor you can hear the differences.

Here's a good link for IDing the digital signals:

That link really helped! I also learned that the signals I copy are much weaker than those screen shots! The best I ever had was one where I could make out the 2 distinct lines of a transmission. My waterfall is solid yellow with while streaks for signal, I must have a lot of noise. Most I can barely hear from the radio speaker. But the machine can decode about 50% of them correctly. Thanks for the assistance!
