It was recorded yesterday morning while I was listening to VA3LK on 137.71 Khz. Sample rate is 8000 samples per second, each sample consists of one 8-bit *signed* byte - i.e. the range is -128 to 127. The signal is relatively strong but there is a lot of noise - I'd be very interested to know how the spectrogram-type programs handle this kind of data. It's nearly 2 megabytes long, so will take a while to download. I don't know how long I can leave it up there. You can download the file called SATRAW.ZIP from my web page at: www.ietc.ca/home/bill/bbs.htm Bill VE2IQ
