Very curious...I think for most PowerSDR users (I have the SDR-1000 and
HPSDR kit) the resolution available via the panadapter is a joy to
behold. Never had a problem differentiating different types of sigs -
AM, SSB, FM, RTTY, etc via their appearance on the display. Something
must not be configured right or the PC/Graphics combo is not up to the
task. Even on my old Pentium 4 with poor mobo graphics I never had
resolution problems. It would be interesting if you could post a
screenshot somewhere for comparison purposes.

Well, I have put the 5000a through its paces, and have some questions.
The panadaptor and scope displays seem very poor, I am used to being
able to see signals much more pronounced, I have adjusted the scale
and other options with no improvement.
Its hard to see (on the panadaptor) how wide an AM signal is, the
scope display does not show the carrier with modulation, and another
odd thing, when an AM signal stops talking, the noise level goes up,
unlike a normal AM receiver where the carrier quiets the receiver even
with no speech.
I can adjust the agc and improve things but it seems to need
adjustment for various signal strengths, where a normal receiver
handles weak and strong signals without any adjustemt needed....
I spent a lot of time compairing the homebrew receiver to the flex,
and the homebrew seems much better in most respects.
I am a little disapointed in the displays on the flex, the resolution
seems very poor, or is there something I am overlooking?
Also, there is no way I can monitor my outgoing audio, because its so
delayed, even if I make the buffers as small as is allowed. That is
partly a slow PC I guess...
