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.

Re: [Flexradio] Flex 5000A Power output
David, I had the same problem here after getting my 3000 back from Flex. It was totally recalibrated after the firewire repair and I knew that it had 95Watts or more, out or they would not have released it. They calibrate the output power at the center freq of each band, and it may differ at the band edges due to component tolerances or aging. This information was supplied to me by Dudley as I was working thru a low power issue. What I found was that I had a marginal connection on 2 of the coax jumpers used between the Flex and the amp and the Wattmeter. One of these was intermittent and was hard to find. Replacing both cables resolved the low power. The SWR at the low power used by the ATU was great, but at the 100watt level was causing foldback of the finals( I believe ). Hope that you have simple solution like this. doug -Original Message- From: David Edwards w...@verizon.net Sent: Dec 29, 2012 10:07 AM To: flexradio@flex-radio.biz Subject: [Flexradio] Flex 5000A Power output My radio doesn't seem to be making 100 watts.

[Flexradio] On the subject of RF grounding
Th may be a tad OT but I hope y'all will indulge me just a bit. I have been following the recent post on RF ingress and RF grounding with great interest. I never had any real problems before with my old 1500 and my kit built 50 watt amp. I had everything grounded to a central point with braid and then that in turn was hooked to a large ground wire than ran a short distance to an eight foot ground rod driven just outside the shack. That probably wasn't good enough and I was going to do more before I had to sell my 1500 and shut down operations for awhile. The only real issue I had that I could not solve at the time was a small tad of RF getting back into my computer speakers on the higher bands. That could have been other things since I used the headphone out of the 1500 to drive the line in of my PC soundcard for sound. I had plans to put up an antenna fed with open wire line that could have further caused RF issues but I never got around to it either. Now that I'm about to purchase a new 1500 and put everything back on the air, I'm thinking seriously about my grounding situation. The room has been rearranged and the location of the station is now about five or six feet from the original entry point of the ground wire. It's not possible to drive a new ground rod any closer either which means the length of the connections to the central grounding point will have to be extended. Putting the room back to it's old arrangement is not an option either. Through a weird set of circumstances, I broke my old radio/computer desk and actually had to just cut the top part of it off and I placed it on an aluminum table for support. One thought I had was to use the whole table as a ground buss. I could make very short connections from each piece of equipment to the table surface itself and then hook the table to my central ground point where my coaxial cables come in. I'm not sure about the feasibility of this idea but I don't know why it would be much different than folks who use a long copper buss bar to ground all their equipment to. I could use NOAlox or some other type of compound to combat corrosion where copper braid or strap met aluminum. Thoughts and suggestions?

Re: [Flexradio] On the subject of RF grounding
After reading this the first thing that came to mind is the Flex-1500 audio out into your computer's sound card's audio input would create a ground loop unless the audio connection was isolated with a transformer. Ground loops induce currents to flow. Too much grounding can be a bad thing. Search for the grounding articles in the Knowledge Base. There is a very good article there on RF grounding. -Tim --- Sent from my mobile phone On Dec 29, 2012, at 4:20 PM, Michael Tondee mat...@charter.net wrote: Th may be a tad OT but I hope y'all will indulge me just a bit.

Re: [Flexradio] On the subject of RF grounding
Yep, that's one of the things I was going to get around to addressing but never did because the only thing I noticed was a slight noise in the speakers when transmitting and it wasn't a real annoyance. As far as the suggested reading, I'm somewhat more confused now because one author doesn't recommend any connections to equipment grounds at all. I've known for awhile I've needed to bond the ground rod outside my shack to the electrical entrance panel ground rod but it's about a 75 foot run and copper strap isn't cheap. I wish the garden variety aluminum ground wire you can buy at Radio Shack would work but everything I've read tells me it won't. The distance from my antenna entry metal plate to the outdoor ground rod is short, only two or three feet but where my desk is now would cause me to have to run six to eight foot long ground wires from each piece of equipment to that central point and that concerns me.

Ground loops induce currents to flow. Too much grounding can be a bad thing. Search for the grounding articles in the Knowledge Base. There is a very good article there on RF grounding. -Tim --- Sent from my mobile phone On Dec 29, 2012, at 4:20 PM, Michael Tondee mat...@charter.net wrote: Th may be a tad OT but I hope y'all will indulge me just a bit. I have been following the recent post on RF ingress and RF grounding with great interest. I never had any real problems before with my old 1500 and my kit built 50 watt amp. I had everything grounded to a central point with braid and then that in turn was hooked to a large ground wire than ran a short distance to an eight foot ground rod driven just outside the shack. That probably wasn't good enough and I was going to do more before I had to sell my 1500 and shut down operations for awhile. The only real issue I had that I could not solve at the time was a small tad of RF getting back into my computer speakers on the higher bands. That could have been other things since I used the headphone out of the 1500 to drive the line in of my PC soundcard for sound. I had plans to put up an antenna fed with open wire line that could have further caused RF issues but I never got around to it either. Now that I'm about to purchase a new 1500 and put everything back on the air, I'm thinking seriously about my grounding situation. The room has been rearranged and the location of the station is now about five or six feet from the original entry point of the ground wire. It's not possible to drive a new ground rod any closer either which means the length of the connections to the central grounding point will have to be extended.

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. 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] [FlexEdge] Phone and CW via network interface, 6700

In a simple case, the 6700 would be in the shack; but, I might be out on the patio operating. When will interface specs be released so we can write our own interface for this purpose, if Flex does not provide this capability? Somehow I think that this has been answered before; but, I can't find the answer. The video was quite impressive...it looks like I can receive anywhere...at my office, on vacation, on the moon! If I can transmit too, I can operate from a location such as Cozumel or Bonaire without having to take a lot of equipment with me! Alas, I doubt that operating in this manner will qualify me as a DX stationdarn.
