Re: [Flexradio] The Flex Insider
Listen to the video again. Greg said that not all of the display controls and slice tuning features are active. Click tuning will be a feature of SmartSDR. -Tim --- Sent from my mobile phone On Dec 30, 2012, at 9:26 AM, Jerry Flanders jefland...@comcast.net wrote: At 11:37 PM 12/29/2012, Stephen Hicks, N5AC wrote: ...

Re: [Flexradio] The Flex Insider
Greg, A keen observation. What you are observing is the different band specific preselectors automatically engaging and disengaging as the HD spectrum view (panadapter) and slice RX are manipulated within the sampled RF spectrum. In the video shown, there is only one frame rate (averaging) being shown no mater the width of the panadapter, so it isn't an effect of FFT averaging. You will be able to select different frame rates to smooth out or make the spectrum display less real time if you want a less busy display.

Re: [Flexradio] The Flex Insider
I need to print a retraction. My previous explanation was technically incorrect. What is happening is that the more you zoom, the slower the frame rate because with each notch lower in decimation, the data output rate gets divided by two. To compensate for this, we change the averaging parameters (there is more than one) to maintain a constant frame rate. So yes, it is an effect of averaging.

Re: [Flexradio] The Flex Insider
Tim (and folks at Flex:) I'm thrilled that a video has been posted about the operation of the new radio. I do have a question regarding the maximum bandwidth: The video demo suggested a 15 MHz coverage. Can it do more than 15 MHz? If so, what is the maximum frequency that it can cover? Will it cover 6 meters and beyond? Also, will there be a way to save each scan in a datafile to load to a spreadsheet, etc., so one can create 3d plots (amplitude vs frequency vs time)? It would be great to see/record the MUF change on a daily basis. Although possible, I'm guessing this option won't come out with the first release. :) Tim Samaras WJ0G On 12/29/12 6:15 AM, Tim Ellison, W4TME wrote: Greg, A keen observation.

I do have a question regarding the maximum bandwidth: The video demo suggested a 15 MHz coverage. Can it do more than 15 MHz? If so, what is the maximum frequency that it can cover? Will it cover 6 meters and beyond? When we announced the FLEX-6000 Signature Series radios, we promised double what we had under PowerSDR -- so 384kHz of bandwidth in the spectrum display. What we'll be delivering is a lot more -- something around 7MHz to either side of the center of the panadapter. You can slide the center of the panadapter anywhere the radio will tune and still see this bandwidth if you choose. We will also have a full bandwidth display that will show around 70MHz of bandwidth at once. The engineering team has worked hard to get the ~14MHz of bandwidth available for every receiver. We suspect that most will want to watch a full bandwidth display and a series of displays that are stretched to the width of the ham band they are centered on. Since the widest ham band is 4MHz (4m and below) we feel most will not stretch the display that wide for the most part, but the capability is there if you need it. Also, I'd like to point out that there is no penalty in client performance for wider bandwidths. This is a subtlety, but it is an important feature of the architecture we designed. The data sent to the client and the load on the client are the same regardless if you are looking at 15kHz or 15MHz of bandwidth in the panadapter. More typically, wide-band architectures must send more data to the client the wider the bandwidth and then the data is processed into the display. This has very negative performance implications for both local and especially remote operation. Instead of doing this (bombarding the client), we use the considerable processing power we built into the platform to use the extra data to build a cleaner display when more data is available. With this, we can achieve 30+ frames per second of display data across the entire 15kHz-15MHz range of bandwidth without burdening the client. Also, will there be a way to save each scan in a datafile to load to a spreadsheet, etc., so one can create 3d plots (amplitude vs frequency vs time)? It would be great to see/record the MUF change on a daily basis. Although possible, I'm guessing this option won't come out with the first release. The data to do this is available, of course. We recognize that there will be a number of great applications that our customers come up with as time progresses -- this is certainly one. Some of these will be so compelling for a large group that we will want to make them available to everyone in a software update. Others will appeal to niches of users and we expect that the API which we will make available will be a good way to get access to the data and to build displays like this. :) Tim Samaras WJ0G On 12/29/12 6:15 AM, Tim Ellison, W4TME wrote: Greg, A keen observation.
