Dear Group, Hopefully I've finally got it right... Inversions every 50 seconds a dozen times then 100s of silence. Hopefully QRV on EbNaut in the near future. I have a long list of 1s and 0's loaded
I'll look out for your signal Joe, although that's a complicated pattern to look for unless we know just when you start your sequence. But if someone gets a strong enough signal it should be a clear
I just looked again at 137.777 and am getting a strong signal with clear phase reversals: In 10 second measurements UT phase 2015-11-21_21:32:10 122.0 2015-11-21_21:32:20 40.1 2015-11-21_21:32:30 85.
I can't do a long average because of the complicated pattern, but a 40 second sample shows 15dB in 0.025 Hz. That means you can use 1 second symbols 8K19A 13 characters. message length 896 seconds =
Hi Joe, phase shift is working - two peaks at +- 10 mHz, as expected. Updating spectrogram: https://dl.dropboxusercontent.com/u/26404526/EbNaut_spectrogram.png Yes the start of the message and the bi
Yes your signal is really good now! Not exactly "audible" here but easily visible in Stefan's QRSS-10 slot, and sometimes faintly discernible in my wideband colour-DF in 0.67 Hz FFT bins. The QRM has
Hi Markus, You and your cat are up late! Unfortunately after a day in the woods with the new aerial, my energy is low and my propensity for error is high so it is perphaps best that I code the EbNaut
I found a way to seamlessly stitch together data chunks from a sequence of partially-overlapping exported FFT's, allowing me to analyze phase evolution over arbitrary periods of time. Attached plot i
