[Elecraft] Impossible mission? USB with the 13khz filter for PSK31 on Digipan

[Tom-N2YTF]

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.

Thanks again,
Tom-N2YTF
