Re: [Flexradio] v1.9.0 Level Calibration
Ignacio: This is even stranger. Where the calibration is done in the code is in console.cs There are NO differences between John Eckerts console.cs calibration and the "official" console.cs in svn 807. I am going to make the usual horrible recommendation.But first I would love for us to blow up the use of MS database tools forever and to use mysql. But given that is not going to happen ;-), I suggest you start over with a clean database just to see if the problem persists in a new database. Just move your database and try it. I cannot replicate your results. In my setup, which is not that different from yours, Delta 44, P4 HT, XP SP2, I get identical results, right down to the same pixel, with and without polyphase no matter what dsp buffer size or audio buffer size is selected.

[Flexradio] Some things worthy of your attention
Some of you are no doubt familiar with the following, but I'd like to point your attention to two books that I've found very valuable and in my ever so humble opinion should be on every serious SDR developer's bookshelf: 1. Peter B. Kenington: RF and Baseband Techniques for Software Defined Radio, ISBN 1-58053-793-6 (Artech House) This tome covers practically all there is to SDR. 2. Jouko Vankka: Digital Synthesizers and Transmitters for Software Radio, ISBN-10 1-4020-3194-7 (Springer) Great detail regarding transmitters with high linearity and high efficiency, two things that usually don't go hand in hand. Regarding the direction for future developments in HPSDR and other projects, I think it might be a good idea to have a look at the new LXI standard for interconnecting measuring instruments via the Ethernet. Ethernet is ubiquitous, cheap and broadband, and lends itself very well for remote control, wired or wireless. Another relevant standard could be the RP3-01 specification from the OBSAI base station standard. This spec defines a digital interface between a remote RF head and the baseband signal processing unit. I think the present SDR-1000 3-board stack with separate audio and control interfaces is not very elegant, to put it mildly. I can understand the initial rationale for using a sound card for the A/D and D/A conversion, after all most PC:s and all laptops have a sound card. BUT, as it turned out, most sound cards aren't good enough, a fact that rather negates the initial idea. We definitely need an all-digital interface between the RF head and the PC, the sooner the better.

I have taken advantage of 1.8.0 to customize the width of all of my filters. And, maybe when I get home, I'll actually post the values up. They're different from the defaults and reflect long operating experience (at least of the sort I do). That's responsive to the original request. What's far more interesting is that I have discovered that the filters can be too narrow on CW! Longtime flexers know that I was originally interested in experiments on 80 meters whereby we'd try and work each other in some clever means with very narrow filtering set. We can now do that, in fact, with 1.8.0. HOWEVER, on HF bands, especially low bands, this is not as impressive as I would have thought. What I have observed is that I can copy code from distant weak stations better at 125 Hz and up (250 is a common choice) than I can at 100, 50, or 25. Right around 100, I get this "too narrow" effect. What happens is, a pseudo-ringing effect. It is not, of course, true mechanical ringing. But, the surviving QRM gets to be more and more like sine waves and so more and more like a true signal. And, probably critically to the human ear, less and less like white noise. So, oddly enough, letting in a little more noise actually increases the effective signal-to-noise ratio of the radio! This makes no mathematical sense, but I have replicated these results night after night. I can only presume that this added noise somehow invokes some of that marvelous pattern recognition power of the human brain to separate things out. Can others replicate these findings? If this was not previously known (and, given the recent nature of SDRs, it might not be), it could form the basis of an interesting finding.

Re: [Flexradio] Pschological peculiarity (was WE NEED YOUR INPUT)
Well that's not as peculiar as it may seem at first blush. After all, many A/D converters, fer instance the LTC2208 (16 bits, 130 MSPS) intentionally add some noise; this called dithering. The idea is to distribute the energy of discrete spurs evenly over the bandwith, thus improving the spur-free dynamic range.

We are in violent agreement. I am absolutely convinced that Vista is the death of embedded processing of the types we need and it will never be on the new radios. It makes no sense to run anything but Linux on the embedded controllers and then have them be a server. I don't care if GigE, Firewire, or PCIe delivers the data.

What DSP buffer size are you using? You will need to use the largest DSP Buffer size for optimal brickwall narrow filters. I know what you are talking about though.

> ... It makes no sense to run anything but Linux on > the embedded controllers and then have them be a server. Um, I respectfully disagree. It may make no sense to run Vista / XP / Windows-flavor-of-the-era on an embedded controller, but if, for example, one wants to embed a DSP inside an SDR, it doesn't necessarily need to run Linux, and the DSP does not have to be Intel or AMD silicon with their many watts of power dissipation. It just needs to do be able to do the signal processing and have a way to get data in and out, get commands in and get status out. SDX and Suitsat2 (aka Odyssey) are examples of this. 73, Lyle KK7P ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/

Yes, switching over to an active receive only antenna I do see a difference now. My noise floor is above -100 dbm and the broadcast stations are being knocked way down. Guess I should have known there would be a threshold level. I also notice that stations are being attenuated by 20 to 30 db within the broadcast band. Ok, here's a request..which I suspect isn't possible..how about attenuation only between 540 KC and 1700 KC so I can listen to LF and VLF signals without having to use a bunch of low and high pass filters in my feedline? :) Thanks and 73, Jerry Sharp, KD0GS [EMAIL PROTECTED] wrote: > Hi Gerald, > > It is working as it should.

I'd have to look at home, but I believe I have always used 2048. If we ever enabled 4096, I suppose I'd give that a try! What I've observed is not the signal getting washed out.

I have a 432 transverter that I plan to connect up to the SDR1000 for the up coming ARRL VHF contest. While thinking about that, it occurred to me that all I really wanted from the SDR1000 was a 10M, 28 to 32 mHZ, single band QRP rig with only milliwatts of power out. By going to a single band design for transverter operation, a significant cost saving and component reduction would occur. 73, Bill NJ1H -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alfred Green Sent: Wednesday, January 03, 2007 11:50 PM To: Reflector Subject: Re: [Flexradio] Price Increase and 1 watt SDR discontinued John Basilotto wrote: >The 1 watt SDR-1000 is being discontinued on Feb 1, 2007. > > > > > Well, Rats!

Re: [Flexradio] Price Increase and 1 watt SDR discontinued
Yes indeed. Those of use with transverters would love something like this. I would change the spec slightly to go from 26-32 MHz and also add some some built in UCB-like control functions as well. The overall market might not be real big but I would think that many of the transverter based VHF+ users would sure like them.

Booting from Flash is not problem for Linux so you could do without the mechanical hard drive. There would be no need to network the radio unless you wanted to ( some do ).

Re: [Flexradio] (A peek behing the curtain) was Re: vSound update from Phil C. - Windows Vista problems
Lyle -- What you're saying makes sense for a (basically) fixed product. It leaves no room for enhancements in the Cognitive Radio area, which *do* require the resources of a more general computer. What we're dealing with is much more a coprocessor than a peripheral of any sort. The high falutin' response to this is, we're in the position of finally treating the radio as a Turing machine, we want to use it as a Turing machine, so why should we turn around and hobble ourselves out of the gate by making it a lame Turing machine? Shouldn't we be giving ourselves the fullest range of capacities first? This philosophy is definitely at odds with power conservation, but it's the price you pay for flexibility in this area right now. 73 Frank AB2KT Lyle Johnson wrote: >> ...

Re: [Flexradio] Pschological peculiarity (was WE NEED YOUR INPUT)
Larry I observed the same phenomenon back in the early 80s while experimenting with switched capacitor filters (anyone remember them?) for improving S/N on recovered audio EME signals. If I remember correctly, I wound up designing circuitry to add a very, very low level of the original unfiltered wide band energy back in so my ear/brain had a reference that allowed me to copy the cw. The problem was the cw had to be slow enough so I could tune the filters, adjust added noise, etc. while I tried to decode. Even so, Carl-W2AZL (SK) and I ran an on-the-air experiment on 144.120 one night and Carl, who lived 35 miles away from me in NJ got down to running 300 mW into a 50 ohm termination in his basement before I could no longer repeat what he had sent on SSB. Heard guys who never joined in our nightly round-table, talking about that experiment for weeks afterward.

Re: [Flexradio] Pschological peculiarity (was WE NEED YOUR INPUT)
Larry, I've observed exactly what you're hearing -- however, I've discovered a cure for that perceived (I think it's psycho-acoustic) ringing. It requires a careful balance of the RF (gain) on the front panel, and NR must be on and Setup > DSP > Options > [NR] Block LMS *must* be checked. I've been using the FA-66 sampling at 48KHz, with the DSP Buffer set to 4096, and the 25 Hz cw filter, with the NR Gain set to about 6 to 8. I notice a dramatic reduction in the perceived ringing as long as Block LMS mode is selected and the NR is engaged but it takes a very careful adjustment of the RF gain to get it to the point where the signal just breaks through the NR. When that happens, it's an amazing thing to hear, and the extremely weak signal just suddenly appears without noise or ringing. It's not something you'd want to have to do for every signal of course, but it works extremely well on those signals that are just barely above the noise floor. (This will only work if Block LMS is enabled for the NR.) Try this same approach with a slightly wider filter and you will hear the same reduction (or entire elimination) of any perceived ringing. 73, Dale WA8SRA [EMAIL PROTECTED] wrote: >>What DSP buffer size are you using?

My vision of this thing was always minimal -- basically, the thing turned the incoming radio signal into bits, and no more, and everything that mattered happened outboard. Doing it that way presumably could be done with a lower component count and a lower power budget. With or without Linux -- I don't care about that, though it's nice to know it can boot fast from flash. I don't care about a front panel, either, though I suppose it could be done. Actually, I probably don't want it, because I'm likely to have a laptop along anyway (and all _its_ battery problems), so multiplying power needs by having a full base-station level of power consumption works against the things I choose not to do with my SDR of today. The thing I most want to see out of a new SDR is not the Second System Effect (where the second project is way bigger than the first and, by the way, often overreaches), but something that keeps the _hardware_ simple and therefore flexible, and yet makes it all much more portable, less wire-ridden and overall more robust and transportable/portable. That is, USB in/out of the AD/DA streams and otherwise the same inputs and outputs all the other rigs have with as good as or better robustness than they have. The software complexity, in my view, belongs upstream. We just need to define some sort of bytes in / bytes out that we can be sure Windows, in particular, won't ever mess with and which is easily understood by those who wish to deal with them. What's being described here is starting to look like a base station only radio. For my interests, at least, that's not progress. If that's what it is, I'll just keep what I have now. I don't plan on a Vista upgrade soon anyhow -- I'm always a trailing adopter. Moreover, as the response to the "1 watt discontinue" shows, I'm not the only one thinking along more minimal lines unless it is all VHFers doing the complaining.

Re: [Flexradio] vSound update from Phil C. - Windows Vista problems
YES! Look at the Tivo. Standalone box. Completely plug & play. Linux on the inside. Output to standard audio and video jacks. Network GUI. Near 0 maintenance. "It Just Works" For the SDR, a separate transmit/rf module should be available but I would expect a lot of these to end up being remote receivers controlled over and feeding IF to the internet. I think investing a lot of time and hard work on something controlled by the whims of an OS company that is actively trying to limit choices and lock in it's customers is false economy. Easy at first and expensive/painful later. Linux (and PowerSDR if I am not mistaken) belong to the community. The freedom to improve/innovate is a VERY important thing. Flex should be commended for NOT trying to lock in it's customers with a proprietary console like another sdr receiver company does. It helps Flex and it helps us. I think their success indicates that it was a good business decision.

[Flexradio] FA-66 and EMI?
Hello Flexers: I have a FA-66 related problem: I've been out of the country for six months, so my SDR-1000 was sitting on a shelf collecting dust. Now that I've come back, I saw that the recommended Firewire interface has changed from the Presonus Firebox to the Edirol FA-66. I quickly put my Firebox up for sale and purchased a FA-66. I did not have any problems with the Firebox, but I wanted the 192 kHz sampling rate that the FA-66 offered. I also recall that getting this out of the Firebox was a problem that Presonus was not helping to solve. My SDR was working fine with the Firebox, so I updated my PowerSDR to the latest version, followed the FA-66 quick start guide from the Flex-Radio site, and started playing with the "new" SDR. It seems to work OK, but I found that I seem to have a BCB bleedthrough problem that I didn't have before. If I tune to certain frequencies ( i.e. LW, 11 Mhz, 16 Mhz, other random locations), the noise level increases, and I can hear what sounds like splatter from a strong MW station. I hear this even if I disconnect the antenna from the SDR-1000, and even if I switch the FA-66 to bus power from external power. I also tried disconnecting some of the other connections ( i.e. line-in) but nothing changed. Is there some possibility that this actually has to do with the board "stack" connectors inside the SDR? Could there be some corrosion or something causing this since the SDR has been sitting idle on a shelf for six months? I haven't changed anything on the PC except the PowerSDR version and installing the FA-66 drivers. I'm using the same antenna, power supply, etc. as with the Firebox. The only other change is some of the cables between the SDR and the FA-66 are different (i.e. the line-in RCA jacks). BTW, I am using the USB/parallel cable for control. Has anyone seen this before? I can provide screen shots and wave files if anyone is interested. Any ideas what might be behind this? Is the FA-66 more susceptable to EMI, or do I have a defective one?

You could get the box to do the dsp (nonoptimized as it might be) anywhere. You can get a complete PC in Mini-ITX form factor with enough crunch to run dttsp for under a couple hundred bucks. You'd be hard pressed to find another DSP solution available off the shelf for that kind of cost. Sure, there's a pile of DSPs out there and a pile of FPGAs, but even in eval board form, they tend to be more expensive than a Mini-ITX. The other issue is development tools. There are a plethora of free (or nearly free) tools for developing on the PC platform (Linux or Windows) but not so many for other platforms. I do a fair amount of work on developing software radios on the Xilinx Virtex II platform, and the tool chain is NOT cheap for those parts, especially if you want simulators, etc. So, you trade off the use of commodity hardware and software for lower initial investment.

Re: [Flexradio] FA-66 and EMI?

Re: [Flexradio] (A peek behing the curtain) was Re: vSound update from Phil C. - Windows Vista problems
The whole point of Cognitive Radio is very simple: it's a radio that can program itself. A corollary of that point is: it's a radio that can and will adapt *by itself* to functioning in response to situations and requirements that *you don't and can't in principle know yet*. So a cognitive radio has to be, first and foremost, a general purpose computer in the technical sense. You might say, well, I can trim all this down into firmware once I've got a sufficient picture of the application domain. Unfortunately, no, you can't, precisely because of the corollary. There's no way around the fact that, if you want a Cognitive Radio, there *has* to be some general-purpose computing power inside beyond the pure "radio" functions, and that's true *no matter how much* you take out of the "computer" side and graft it onto the "radio" side. It's a theorem. Two theorems, actually. One of them is due to Jorma Rissanen concerning the asymptotic nature of certain binary sequences, the other being the Halting Problem. To give up on that is to have something other than a Cognitive Radio. Now, whether a Cognitive Radio is what you want (or need) is a wholly separate question. But in the end that's what determines whether you want a "computer" or something else inside your box. 73 Frank AB2KT Jim Lux wrote: > At 08:31 AM 1/4/2007, Lyle Johnson wrote: >>> ...

Re: [Flexradio] FA-66 and EMI?
Is the direct monitor knob fully CCW? If not, you may be listening to the IF as well as the demodulated audio. This would come out around 11kHz and would sound very annoying. I would recommend that you go back carefully through the quick start guide to make sure that this and the other controls on the unit are set properly (assuming you haven't already done this).

Re: [Flexradio] FA-66 and EMI?
Larry, I have a similar situation at 13 and 15 Mhz. Different versions of SW seems to have no effect. I have a "plug n play" system from Flexradio, about a year old, with no mods and a D44 sound card. I don't remember it being there at first, but I have not kept track of when it started. It is no problem for me so far, just a minor aberration. I am pretty sure it was not there until I moved to my present city location. I will be interested to hear of a solution though. :-) 73, Fred WA8KCW - Original Message - From: "Larry Gadallah" <[EMAIL PROTECTED]> To: "Flex-radio Reflector" Sent: Thursday, January 04, 2007 1:13 PM Subject: [Flexradio] FA-66 and EMI? > Hello Flexers: > > I have a FA-66 related problem: I've been out of the country for six > months, so my SDR-1000 was sitting on a shelf collecting dust.

[Flexradio] FlexRadio Digest, Vol 21, Issue 4
Hi Flex Radio users ! Issue: 1 W SDR1000 units gone! For quit some time, I am using a little 10 W Linear Ampl. driven directly from the built in 1 W Opamp. with only 100mW output I get easy my needed 5 - 7 W. to drive a larger external Linear Amplifier The Ampl.-Kit is sold in Germany by the Magazine 'Funk Amateur' for about 50 US$ Issue: SDR1000 - Mixw2! Then something for Mixw users. The newest release of Version Mixw 2.18 contains a bug. The Mixw team, increased in their newest version the Catspeed Therefor when using Mixw with the Kenwood/All protocol, (which is recomended) as CAT setting for SDR1000 - Mixw2, then using the mousewheel to change frequency, turning the wheel to fast, it sets the frequency 65.000 Mhz. So to me, the mousewheel setting is useless. A recomended change of the value of: m_icatdelay to 200ms in the mixw.ini file did not fix it. The autor of Mixw told me, that at the moment that they dont want to change anything back to what it was before. ( Maybe later?)

That's responsive to the original request. > > > Here's my current filter settings. First, I always use CWU unless very close to the band edge. This works better for DX pileups where "listening up" is the norm. Second, for now obscure reasons, I use 400 Hz, not 600 for my listening frequency. This was originally to placate the wife. I can still use other values, but I like this because small changes in Hz make big differences in tone. Filters are currently set (on CW) for: Width (Low-High) 25(387-413) 50(375-525) 125(338-462) This is where the "psychological" effect starts to kick in. 100 is still too narrow. 250(275-525) 400(200-600) 500(150-650) 600(100-700) 750(25-775) 1K(-100-900) 2K(-600-1400) Generally speaking, the frequencies are centered on 400 Hz. This helps me find signals in "simplex" DX pileups where I had tuned out the other guy, except now he won and I want to know where he is. The values for frequencies above 400 aren't terribly critical and might be set "unbalanced" now and then to listen to the "whole pileup" if it is narrow enough. I've been experiementing with dual receive for that also (mostly I use a wide filter in a single receiver mode that I customize so I can hear both with the equalizer set to attenuate higher Hz values). The dual receive, since one bandwidth fits all, has been a bit problematical, but easier to listen to. The other item worth a brief comment is DIGU, which I use for RTTY. I suppose it should be DIGL, but DIGU works fine once I get it set up right. MixW seems to handle it. I mostly use a hand-set variable width and I use MixW's waterfall to set it. The idea is to again center mark and space (for whatever mode I'm in) around 400 Hz. This is mostly to deal with MixW's peculiarities. Basically, the sharp skirts, when I get it all set correctly, enables strong adjacent signal rejection (very common on PSK31) and I usually _must_ back off on the Preamp control or else the incoming signal is too strong (noisy)! But, I get some jim dandy results on both RTTY and PSK that way.

[Flexradio] No 1 watt units
Regarding the future absence of the 1 watt unit, will there be a QRP port? That is absolutely necessary for transverter work. Perhaps the new unit will have better transverter capabilities. I would think that as many as I encounter doing VHF/UHF work with the SDR, that the qrp unit would be more popular, I know it's the only SDR I own. Perhaps many qrp users also work low bands, hence acquire the 100 watt unit. My plan had been to get one with the high power option in the future.

Re: [Flexradio] FA-66 and EMI?
Can you transmit? I had a similar problem when I started with the FA-66 and it turned out to be a problem in the SDR-1000. I sent it back and they replaced 2 resistors and a choke, but they didn't list exactly what resistors and choke they replaced. Once I got it back the FA-66 tuned up perfectly. 73 W9OY __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [Flexradio] PowerSDR Crash SVN819
Hi Tim SVN 801 works all OK with my present drivers. The crash in SVN819 seems to occur when using the Sub RX. Have been running SVN 819 ( It says 819 on the top of the display) for about 30 minutes without the Sub RX and no crashes yet. Will let it run for a while then tomorrow will try the dual receive again. Since it seems to be working have added N1MM with MMTTY using VAC only for output and the other computer feeding AFSK into the D44 3/4 input (CPU load about 38%). A "Y" connector feeds the audio to the other computer also running N1MM (controlling the simulated Kenwood) using MMTTY for Demod. This allows the use of two different demod profiles, depending on condx. Where did you get SVN821? 73 de Jerry NO2T At 10:49 PM 1/4/2007 -0500, you wrote: >Try update your video / graphic card's drivers. > >Is this all of the error text? > > >-Tim > >Integrated Technical Services >www.itsco.com > >"Si fractum non sit, id reficere" >-Unknown Roman consultant > >-Original Message- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] On Behalf Of A.R.S. - W5AMI >Sent: Thursday, January 04, 2007 10:39 PM >To: FlexList >Subject: Re: [Flexradio] PowerSDR Crash SVN819 > >On 1/4/07, Ken N9VV <[EMAIL PROTECTED]> wrote: >> working like gangbusters for me - shows SVN 821 on top of my PowerSDR >> window. > >Not me... > >I have been getting this same issue when I switch from VFO A to B.

Re: [Flexradio] PowerSDR Crash SVN819
I close my case, as everything seems to work fine now. Not sure what has changed, or what I changed myself. I've tried switching VFO's at least 20 times now, and it works just as it should. This happened three or four days ago and I haven't tried it since. First time I ever saw the BIG X in the display! Since it seems to be fixed now, I won't question why ;) 73 Brian / w5ami PS: My processor is an AMD, not an AMD Pentium as I stated before ;) First AMD I've ever had.

Re: [Flexradio] PowerSDR Crash SVN819
OK, it took me a while to find it, but a dormant neuron fired when I saw the big "X" statement. There were problems listed that the "X" was a symptom. This is probably due to a conflict with DirectX. Make sure you have the most up to date version of it and of your video driver. Refer to the following KB article for where to get the updated DirectX files (the latest is 12/13/06) http://kb.flex-radio.com/article.aspx?id=10133 -Tim Integrated Technical Services www.itsco.com "Si fractum non sit, id reficere" -Unknown Roman consultant -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jerry Sent: Thursday, January 04, 2007 10:22 PM To: FlexRadio Subject: [Flexradio] PowerSDR Crash SVN819 All of a sudden am having system instability!

[Flexradio] 1.9.0 and occasional cw popping in tx
Is anyone experiencing occasional snapping or popping on key closure in cw? I'm finding that the radio infrequently kicks out a very brief snap either at the onset of tx or on first key closure. Almost sounds like a static discharge. Receive is perfect and the various buffer setting combinations have no effect. I'm keying the radio via com1 using an external keyer, however this seems to occur using the internal keyer as well. Thought I had it licked the other day by dropping the FA-66 latency values to their smallest values however I've noted the condition again tonight running svn 821.
