I do not how you use the bandscope but I find it very useful. Not only can I
look at is the band bust and quickly find a free frequency. I can look at
someone's audio and see where the highs and lows roll off.

One thing almost as useless is the "scope."

I have been using the Flex 5K with Win7 64bit running on an i7 with 12 gb
memory for about 5 years now. Have upgraded software at least 4 major
revisions now running v2.7.2 PowerSDR. This is an awsome radio and my best
radio. Currently have 2 other HF radios: IC7800 and TS2000 and have had
many Kenwood and Yaesu radios over the years.
There is one area where the Flex 5K falls down and has not really ever
worked. The DSP noise reduction is useless. Over the years I have not seen
any situation where switching on NR improves the ability to copy a weak
signal. The IC7800 DSP NR is FAR superior. When I purchased the Flex at
the Boxborough Ma hamfest the canned demonstration showed incredible
signal improvement using NR. So I wonder when the NR will ever be improved
to at least the usable state.
BTW I’ve tried every conceivable setting on the DSP and Audio config.
pages, have lots of processing power and lots of experience with SDR’s. I
work with the most expensive SDR everyday of the week at my job: The
General Dynamics DMR, at $500K per copy this isn’t comparable but my point
is I’m not new to SDR. That said if I’m missing something I’d like to hear
from others who may have had a different experience. Again I think this is
a great radio just not great DSP NR.
