[Flexradio] DSP NR
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. ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/

Re: [Flexradio] DSP NR
I find the biggest adjustment I use other than playing with the taps is AGC-T, but I am sure you have tried that already. I have had success with knocking down noise in my plasma tv infected home station. I don't have the same issue with my remote base, and there I use just a TS480 which hears so much more as the noise floor is just that much better.

Re: [Flexradio] DSP NR
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.

Re: [Flexradio] DSP NR
From the Flex 5000 operating manual: The Scope Display shows the received or transmitted audio signal in the time domain. The Scope Display is particularly useful when transmitting to monitor your audio waveform, e.g. to see the effects of DX (page 82) or equalization (page 109). The time base can be adjusted on the Setup Form- Display Tab (see page 141). I found it to be very useful.

Re: [Flexradio] DSP NR
All Since David has been using the radio for 5 years, he know how it works, he knows you have to adjust the AGC-T levels and tweak the NR settings in Setup. It does reduce some types of noise. It can also distort signals. I wish it worked better too. I think the NR button is all about wishes. You hear noise. You wish it would stop. You wish VERY hard. You press NR. And the noise is still there Wishes work better in fairy tales. But we have a button. Flexradio included the NR button so we could all wish Wishing won't make it work though. Somebody will have to fix it in the software. If wishes were horses, then dreamers would ride. Yes they would. I wish I knew how to write software well enough to make the NR button work. I just pushed the button again. Worked about the same as before. Let's make it a contest then. First person to rewrite PowerSDRs NR code work so that it works... wins! What does he win? Anything he wishes! I have discovered that there's another button in PowerSDR that does noise reduction and it really works. It's also mislabeled they put the word Mute on it. But I like the way the NR button works better! The dreams get better and better just like i wished. Sent with a smile and best wishes!:-) On 2/23/2014 5:23 PM, David Edwards wrote: I have been using the Flex 5K with Win7 64bit running on an i7 with 12 gb memory for about 5 years now.

Re: [Flexradio] DSP NR
The Scope display is also useful when used while adjusting the useless NR button. I like the Scope display i like the Pan_A_Scope display even more. I don't see much use for the histogram and phase2 displays though. What are they for? On 2/23/2014 8:30 PM, Julius Jones (Prodigy) wrote: I do not how you use the bandscope but I find it very useful.
