I don't use Digipan but I doubt if it is capable of displaying that big a slice of bandwidth. The maximum that can be received is half the sampling rate the software uses. Many of the older digimode programs use a sampling rate of 8KHz or 11.025KHz. So my first question is what sampling rate are you using?
Thanks for the advice.....I am running at 12Khz, giving me a 6Khz receive limit on the computer...good point. Still, I can only get about 4Khz out of the K3 even though I have the 12Khz filter, and I wouldn't be surprised to find other software out there that will go much wider. My second question is, what is the point anyway? All the PSK31 activity here takes place in a bandwidth of about 3KHz. I guess a lot of the time that is true, but certainly during the PSK 31 contests things broaden out a bit. So a 4KHz waterfall would show you all you wanted to see. If it covered any wider then stations operating close together would be hard to tell apart. I don't understand what you mean by that. Why would they be harder to tell apart if I had more bandwidth? I don't want to run broadbandwidth all the time, just long enough to find somthing interesting and then I want to narrow down to 50Khz (I also have the 200hz filter) to peak it up. Actually, that brings up another point, I wish the filter shift would move in increments smaller than the current increment so that I could really zero in on psk31 signals, as they are so close sometimes, and I like to operate in the smallest bandwidth possible.
