Talk:Adam H Image Capable Digital Mode (AHICDM)
Where was this sample found? -WAW
Currently am wondering the same thing. This does not sound like it came from an actual RFRadio Frequency source. And neither does it sound like it was even used in radio. Probably was simulated.
You only simulate signals and their waterfalls if they are requested from the requested signals page, or if they are already posted with actual RFRadio Frequency waterfalls and documentation. And you must be able to do it correctly through an actual transmitter on the actual frequency range with the correct hardware designed for it.
Sure, you can use a soundcard (most of the time with VB audio cable), to simulate FMFrequency Modulation in a poor fashion with audacity's special nyquist code that I found on a forum post on the audacity site (thanks to Robert Haengi), along with other modes using similar methods, and then add noise to emulate the actual signal. But that is actually not a good way to do so according to what ive heard from dozens of individuals. I only done that with the AFSKAudio Frequency-Shift Keying Paging link page's simulated examples to show the actual signal itself *if* it were actually transmitting. I only normally show it as a demonstration. -> Yalek W.
