[Flexradio] PC Recommendations for SDR-1000
Title: PC Specifications for SDR-1000 Hi all, I think my inquiry may have been lost in the noise and fury of the e-mail barrage of the past two days, so I am re-posting my request in the hopes that I can get some additional feedback on my questions other than use LINUX. At this time LINUX isnt an option. Maybe it will be in the future.

What performance metric is most desirable in a CPU / motherboard combination? I want to make sure I get a system that will meet current and future performance needs. I have not done a lot of research on the DLLs or libraries used, so I was hoping to get some insight from those that know a lot more about the internal operation of PowerSDR than I. Specifically, what is most to least important of the following items (a ranking of sort): Floating point performance Integer operation Memory performance Multi-tasking performance CPU cache Graphics performance In addition to processor / motherboard metrics, has anyone used Windows XP Professional x64 with PowerSDR? If so how did the WOW64 emulation handle PowerSDR and is there any advantage to using a 64-bit OS. Will PowerSDR be compiled to be a 64-bit app in the future? Also, are there any known compatibility issues with AMD processors? In advance, thanks for the information. 73 de W4TME -Tim --- Tim Ellison Integrated Technical Services Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers

Re: [Flexradio] Windows ME
A wise old shaman once said Windows bad. Windows ME VERY bad PowerSDR might run on it, but I support a lot of diverse IT environments and Windows ME has so many incompatibilities with so many things and is not very stable. Our standard method of fixing WinME problems is to upgrade to WinXP. It has worked 100% of the time. The little money spent for the upgrade significantly out weighs the pain, frustration and expense of trying to resolve ME driver issues. MS should have never released ME. I would not recommend anything less than Win2000 for any serious computing endeavor. If you can afford it, the Win2003 core is better than Win2K and WinXP for security and code execution. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Tracey Sent: Tuesday, September 20, 2005 12:16 AM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Windows ME The specifications page on flex-raioo.com lists Win 2000 and XP as supported operating system.

[Flexradio] Request for a new forum on eham.net
Forum Master, I am requesting that eham.net add a forum to provide a dedicated informational single point of presence for the emerging interest in the next generation of ham radios, specifically Software Defined Radios (SDRs). A forum name of the same would be most appropriate. There is an emerging, but very technical group of people who are rapidly advancing the maturity of software defined radios. SDRs will become the future of ham radio and provides the radio amateur with a way to experiment with his equipment in a way not available today with rigs from the Big Three due to open source software. Granted, you are experimenting with software rather than circuits in most cases, but with who else's equipment can you design your own AGC system? I know only of one - Software Defined Radios. SDRs are a unique evolution of radio design and should not be generically lumped in to a forum about computers and software as they relate to Amateur Radio. It deserves it own forum. I know for myself, I became very interested in SDRs a few months back and used eham.net as one of the first resources to find information on this subject. A search of the web site lists numerous articles on the subject, but very few hits in the forum section. I believe this is because there isn't a clearly defined forum area for discussions related to SDRs. With the group of hams that is currently supporting SDRs, I feel that you will have a forum that provides a high level of technical information that would rival that of the Elmer's forum in this regard. Since eham.net is premier ham radio web portal, I believe that a lot of hams would benefit from a forum dedicated to this new aspect of ham radio and will become interested due to the exposure given to it by having a dedicated forum on the topic.

Re: [Flexradio] Eham Review
Bom dia. Oi. For me, this was an informative and interesting review. I am very seriously considering the purchase of an SDR-1000. In preparation, I have upgraded my computer, purchased the Delta44 and Eric's ground isolation kit. The only thing that has prevented me from purchasing one to date is that I had to leave the country for 2 months on business. I am going into my SDR-1000 adventure with my eyes wide open. I am aware that the software is a work in progress and that this is not an appliance operator type of radio. No problem. I've lived on the cutting edge before so I know what to expect. The support and contributions of this group also has lessened my fears that the ~$1500 will be a well spent future investment. What concerns me is that a core part of my reasoning for going ahead with the SDR-1000 purchase was based on the assumption that the hardware component of the radio was, for the most part solid. I am aware that there have been minor improvements in the past to correct issues. That is to be expected. But the e-ham review brought up some interesting issues. Mostly about the construction quality, PA oscillations and RF susceptibility. I realize that one review doesn't properly describe the true state of things, but along with the other threads on this forum about problems being attributed to cold solder joints, I started wondering about my future purchase. The rebuttal e-ham review by KD5RD clearly defined the well known accolades and potential issues of *software* defined radios but doesn't address any of the hardware construction issues raised by AA8VL. Therefore I am interested in the discussion that this review will generate in this forum and also on e-ham. Hopefully my fears will be abated by the responses.

Though were going at this both as a fun/casual vacation with radios - with some wives along - were also out to prove the viability of SDR technology in a DX/contest environment. Now to the point of this email, and where it strays off topic. Terry and I were trying to get our respective SDR computers interoperating through my home network yesterday to test our design. I have a Linksys 80211.g router set up as a secure (WEP encrypted) network access point and we were having problems getting Terry signed on to the router. After banging on it unsuccessfully for several minutes I suggested we call Linksys tech support on the phone. Id called them before on a previous setup issue and mentioned to Terry that Linksys phone support (free) had always been very good. So I dialed them up on the speakerphone and after the obligatory automated operator maze and (our call volumes are unexpectedly high) five minute wait we were greeted by a live, but very Indian, female support person. (I could see Terrys eyes roll.) As I had experienced on a prior call to Linksys, this was not your usual Indian tech support call. This lady was all business - focused, knowledgeable, and wasted no time getting our problem sorted out. VERY impressive! Im an unabashed user of customer support phone lines when I run out of runway with online help, but theyve mostly gone down the tubes with all the shifting to cheaper offshore support mills. Linksys, too, has gone to India with their phone support, but its IMPECCABLE! Leaves one to wonder why the huge gap. Bottom line, I *WILL* buy Linksys products in the future. Gary W5ZL
[Flexradio] Microphone recommendations
Title: Microphone recommendations I finally ordered my SDR-1000 yesterday (yippee!) and I am eagerly awaiting its arrival. In the mean time, I wanted to ping the group on microphone types to use with the SDR-1000. I'll be using the Delta 44 and will feed the mic directly into the soundcard. I noticed some where on the Flex-radio web site that there is a reference to using dynamic Heil microphones and was wondering what the good, the bad and the ugly was on using dynamic mics. Do they drive the soundcard without having to use a preamp?

I have recently received my SDR1K, but unfortunately I am in a different hemisphere that the radio.

The XG-1 should work fine. A stronger signal would likely give you a better chance of getting a better null (you will run into the noise floor much sooner with the XG-1). You can use another transceiver if signal level is an issue though. The actual signal level and signal frequency used for the image null isnt really important (unlike the Frequency and Level calibrations).

Pardon, the basic newbie questions, but I just want to make sure what I am experiencing is the norm. I have noticed that if I engage the DSP, the audio volume decreases by about 40% (subjectively).

Re: [Flexradio] Pentium M
To answer your question, I assume you are going to run some flavor of Windows on your new laptop. Laptop hard drives are slow compared to their desktop counterparts. In order to reduce the possibility of extensively using the swap file, get the extra RAM. It isn't that expensive in the grand scheme of things and you will always find a way to consume it. With several applications running, you will probably only use 256 - 384 MB during normal operation unless you are loading a lot of large database tables into RAM . -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Lee A Crocker Sent: Monday, November 14, 2005 8:32 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Pentium M Thanks for the response.

[Flexradio] A simple fan noise abatement modification
One of the first and only negative thing I noticed about my SDR1K on its initial setup this weekend was how much fan noise there was with it sitting on my desk. Since I knew that the fan noise was being picked up by the microphone and I really didn't want to put the unit under the table (can't show it off when it is out of sight), I decided to do a little research to see if there was something I could do to reduce the fan noise and share the process with the group. My first though was just get a quieter fan. I first removed the fan from the front panel so I could get the part number and retrieve the data sheet from the web. What I discovered was that the specifications of the fan used by Gerald crew in the SDR1K are the upper range compared to other 80mm X 15mm fans. No skimping here - Thanks Gerald! As per the data sheet, the fan provides 22 CFM airflow @ 2000 RPMs generating 23 dBA of noise. After an extensive search of the Internet I could not find a fan with better specifications. So, the quick fix was out of the question (isn't it always) It didn't take too much effort to figure out that a large component of the fan noise was the volume differential between the fan intake vent and the volume of air being drawn in by the fan. Just by looking at the air intake holes located within the area of the fan casing, it was fairly evident that approximately 50% of the total area was blocked. A simple test of this theory was to fire up the SDR1K while holding the fan next to the chassis vent holes and moving it away by 10 mm. The fan noise decreased at least 80%. Now I had two options. One was to use small stand offs on the fan mounting screws to decrease the pressure differential or modify the chassis to allow more air through the fan intake opening. Not wanting to disturb the laminar air flow by creating an inefficient open loop, I opted for the later option. The mod: I disconnected the power switch, mic connector and fan and then removed the front panel from the chassis. Using the outside of the existing air holes as a guide, I scribed an octagon on the front panel by creating a tangent across three successive vent holes creating eight sides. Using my trusty Dremel tool (a most excellent toy) and a metal cutting wheel, I cut out the octagon traced on the front panel. You want to make sure you don't do any metal work with the electronics in close proximity since the cutting process creates very fine metal dust that gets everywhere.I smoothed up the rough edges with a grinding wheel and then used a little flat black paint to cover the exposed metal edges. I replaced the front panel back into the chassis along with the mic connector and power switch. When I reinstalled the fan and the bezel, I used some small flat rubber washers in between the fan and front panel to dampen the harmonic vibrations the fan induces when the fan is running. I replaced the snap-on dust filter and fired up the SDR1K. The results were instantaneous and absolutely amazing. I probably reduced the fan noise by 100% easily. The fan in the Astron SS-30M is louder than the SDR1K and it is a relatively quite fan. One added benefit of the modification was the increased volume of air flowing over the PA heat sink increased its thermal dissipation efficiency. Subjectively, I could feel more air flowing out the exhaust holes and the temperature of the exhaust gas was somewhat less than it was before the modification. The whole process took less than 30 minutes to complete (minus the time to go the Lowes to get some rubber washers). I now wish that I had a way to measure airflow and to take some before and after temperature readings of the exhaust gas along with some pictures documenting the process so I could provide a more complete assessment of the benefits resulting from the modification. All I know is the SDR1K is much, much quieter, the PA runs cooler and since the fan experiencing less mechanical and thermal stress, it should last longer. I have a large (500 MB) close up jpg of the finished product without the dust filter if anyone would like to see it. Just send me an e-mail directly and I'll forward it on. 73 de W4TME -Tim --- Tim Ellison mailto:[EMAIL PROTECTED] Integrated Technical Services http://www.itsco.com/ Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers
Re: [Flexradio] A simple fan noise abatement modification
True, but the fan in the SDR1k needs an 80mm X 15mm format (very thin) and I could not find one in that format that had the temp sensors that were not 10-20 dBA louder than the fan currently installed. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Clark, W3IWI Sent: Wednesday, November 16, 2005 12:18 AM To: Paul Wade W1GHZ Cc: FlexRadio@flex-radio.biz Subject: Re: [Flexradio] A simple fan noise abatement modification Paul Wade W1GHZ wrote: another way to reduce fan noise is to reduce the speed of the fan. one of my recent projects is a fan controller with speed proportional to temperature, with the temp sensor wherever you like.

Re: [Flexradio] FlexSDR software and Multiple CPU's
Cecil, I am running an AMD Athlon dual core 4400+ on Win2003. With PowerSDR, logging software, MIXw, VAC, Vcom, Firefox and a Citrix session for e-mail, my total processor utilization is about 10-15% max. About 8% on the average. All of that is on the first processor. Less than 1% is running on the second processor. From what I can tell, PowerSDR is not specifically written to take advantage of dual processor machines. When I look at the processor utilization, ~90% of the total CPU utilization in on the first processor. As you continue to add application load, it will mostly consume the first processor until the load gets to about 50% (assuming no single process exceeds 50%) and then new processes are run on the other processor. This is mostly a function of the operating system and not the application. I would suspect that the multi-processing logic is a little more robust on Win2003 than XP. In my testing, most things being equal, two 1 gig processors will not outperform a 2 gig processor. Multi-processor aware applications specifically choose how to distribute their process between the processors. But, with the current incarnation of PowerSDR not really pushing the processor on very fast machines, for now it is a moot point. Although I'd like to see how a multi-processor aware version of PowerSDR would behave and how specific application processes would be divided among the processors. Having the graphics run on one and the FFT and signal processing operations run on the other would be interesting. -Tim From: [EMAIL PROTECTED] on behalf of KD5NWA Sent: Thu 11/24/2005 11:51 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] FlexSDR software and Multiple CPU's Will the existing Flex software take advantage of a PC that has multiple CPU's?

[Flexradio] Loud audio pop during band changes with 1.4.5p7
I have noticed that there is a loud pop heard in the speakers every time I change bands or use the band stack registers to go to another portion of the same band. It only does it when the relays kick in. On 160, 80, 60, 30, 17,12 6 meters the initial band change results in a relay clack and a loud POP. Changing to different parts of the 160, 80, 60, 30, 17,12 6 meter band using the band stack registers does not produce a relay clack and there is no popping noise no mater how many time you change frequencies with the BSR. On 40, 15, 10 meters the initial band change results in a relay clack and a loud POP. Changing to different parts of the 40, 15, 10 meter band using the band stack registers does not produce a relay clack BUT there is a audible popping noise, but much quieter that the initial POP no mater how many time you change frequencies with the BSR. If I am changing between the three BSR settings on 20 meters, I observe that the first two band changes I hear the relays clack and hear the load pop. One the third band change, I do not hear a relay clack and the audible pop is much lower in intensity almost like a click rather than a pop. Then the pattern repeats itself if I continue to change band stack register - Pop, Pop Click. This problem is 100% reproducible. This is all observed with version 1.4.5 preview 7. Doing the same test listed above on version 1.4.4, I hear an relay clack when I initially change to a band, but NO popping. Change to different frequencies within the same band using the BSR produces NO popping. This behavior is the same on all bands. Even 20 meters, I do not hear the multiple relay clacks using version 1.4.4 like I do with 1.4.5p7 Configuration: AMD Athlon dual core 4400+ 1 GB RAM Delta 44 Standard SDR1000 configuration without tuner or transverter -Tim --- Tim Ellison mailto:[EMAIL PROTECTED] Integrated Technical Services http://www.itsco.com/ Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers

[Flexradio] Interesting behavior when connected to a dummy load
Title: Interesting behavior when connected to a dummy load I was testing tonight into a dummy load and noticed some very peculiar behavior. When connected to the dummy load on 14.179 MHz (USB) I see the noise floor (signal) in the panadapter as a flat line from -10K to +10K Hz at about -145 dBm. That looks good to me Now I change frequency to 14.178 MHz and I see the signal rise to -130 dBm between -10K and -9.5K Hz. It is flat at -145dBm across the rest of the spectrum. Looks like more noise on the low end. Not so good. If I change the frequency the to 14.177 MHz I see the signal rise to -113 dBm between -10K and -9.5K Hz. It is flat at -145dBm across the rest of the spectrum This shows a *lot* more noise. Here come the strange part. I change the frequency to 14.176 MHz and the signal looks just like the signal on 14.179. Flat across the entire spectrum at -145 dBm. By changing the frequency down one kHz to 14.175, I see the signal that looks like 14.178 MHz. A small rise to -130 dBm at the low end again. If I decrement the frequency down an additional kHz to 14.174, I see the signal that looks like 14.177 MHz. A large rise to -113 dBm at the low end again. This pattern repeats itself through out the entire 20 meter band. The rise in the noise floor is a little less in magnitude at the very bottom of 20 meters (14.050), but by the time I get to 14.150 the rise in the noise floor is back to approximately -110 dBm. I checked other bands and it exhibits this behavior on ALL bands. Always a three kHz stepping to repeat the pattern. Anyone have a clue what might cause this behavior?

[Flexradio] First OLIVIA digital mode QSO with SDR1K
After getting MixW working correctly, Hoping VAC wouldn't generate a BSD and downloading the latest beta version that supports OLIVIA, I was able to have a successful QSO with YV4GMH, Hector in Venezuela. Olivia is a new data mode which is excellent for poor conditions. It's a wideband data mode using error correction and a modulation method similar to MFSK For more info, you can check out this URL: http://homepage.sunrise.ch/mysunrise/jalocha/mfsk.html It is a very cool digital mode. It sounds like a bunch of sparrows fighting over a bread crust!! Much more pleasant to listen to than PSK.

[Flexradio] A question about PA calibration
First off, I am not having any problems running the PA calibration routine. It works fine. The PA gain test results I received with the radio all fall in a range between 48.7 and 47.7 with a large majority being 48.0 dB When I run the PA calibration into my dummy load, I get much different numbers The range is between 65.8 and 55.0 with a large majority being 64.0 dB Should I be concerned about this relatively large discrepancy between Flex-Radio determined gain test results and my own?

A counter-point is needed. First off, I'd never think about running Windoze on my Yawoocom. :-) Even with traditional radios these days, the PC is an integral part of operating. Not critical as it is with a SDR, but still a very important part. I have to disagree with your statement Most folks don't, and leverage an existing PC into being the radio as well as the PC. Or buy a new PC for the SDR-1000 and leverage it into being their shack computer as well. I contend most do. Those who can, will buy a new machine that should be able do it all. Those who can't, will make do with what they have and not want to for go exciting things like digital modes, contest software and Internet access at the expense of just having a radio. As a new SDR user, I bought a new PC specifically with the SDR in mind, but in this world of multitasking multicore multiprocessors it would never occur to me to use a PC for a single function unless it was a mission critical business app, such as e-mail or a database server. With processor power going up and prices staying about the same or even going down, you can get yourself a very powerful machine for about a grand and a half. And to be just as fair, why *should* I have to use a dedicated machine. I am only maxing out 15% CPU utilization with the one I have now. What a waste of a lot of good and resources. I specifically want to run multiple apps on the same machine as the SDR1K. We do that today for those who are using digital modes. I couldn't live without having a logger and an Internet based call lookup running at the same time along with e-mail so I can get the very latest scoop from the Flex-Radio reflector. Call me selfish, but after graduating from DOS 14 years ago, I really don't have any great desire to go back to a single tasking way of life. Yes, something does have to give as you say. That would have to be the single tasking, monolithic computing paradigm that you are wanting us to revert back to by throwing dedicated hardware at the SDR challenge. Sorry can't do that here. The SDR desktop will be a point of contention for a long time to come. And that is a good thing. Obviously it will get better. Much better. There are a lot of different ways to optimize the GUI. Using tabs and layered screens is just one way to increase real estate without resorting to increasing the footprint. This is an area where development should not be stymied just because it is easier to buy more monitors. At some point you are going to run out of desktop real estate to put all those monitors. I would hope that just because it is easy to fix a problem by throwing more hardware at it, that doesn't become the way out. If so, innovation dies. And as far as I can tell, that is not what the developers here have been doing. If the DSP and FFT code runs slow, they find better libraries, use advanced features of the processor and optimize routines, not tell you to by more machine. I certainly hope we don't start taking steps backwards. I am looking forward to the new PowerSDR architecture and the possibilities it brings.

Re: [Flexradio] SSb and Digital
Ross, That is exactly how it works in 1.4.5p7. If the Auto Enable setting in the Setup-Audio-VAC tab it selected, then when you select DIGIU or DIDGL mode VAC is automatically engaged. Changing to a non-DIGIx mode disengages VAC. I know this action well, because it is the switching of VAC on and off that is directly responsible for the Blue Screen of Death when the VAC system driver tanks. You can see this behavior if you have the Setup-Audio-VAC tab open, when you switch to a DIGIx mode, the Enable VAC check box will automatically check itself. Switching to a non-DIGIx mode, the check box will uncheck itself. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ross Sent: Thursday, December 08, 2005 2:12 AM To: FlexRadio@flex-radio.biz Subject: [Flexradio] SSb and Digital Thanks Greg, you picked up my error.

[Flexradio] Feature Request: TX Profiles
I'll just throw this question out and anticipating a specific answer, see if anybody else thinks a feature like this is something that would be useful. First the question: When using the new DigiL and DigiU modes, the TX audio processing is bypassed. Is the TX bandwidth filter bypassed (fixed) or does it use the bandwidth set in the current TX profile? Anticipating that the TX bandwidth is not fixed and can be controlled by a TX Profiles, here is my suggestion. First off, I like the TX profiles. I have read several posts about expanding this feature to include some of the other rig's settings in the TX profiles database and I wanted to add my $0.02 worth. Assuming that when in DigiU or DigiL mode, I am utilizing whatever the current TX profiles bandwidth is, this thought came to mind. I have gone into the database and added several profiles for use with digital modes. Specifically, making the TX bandwidth narrower since I don't really need 3K of bandwidth for a 300 Hz signal when operating in ASFK mode. When using the new DigiU or DigiL mode, the audio routed through VAC bypasses any and all of the TX processing. Currently, Mic Gain is one of the data elements stored in the TX profiles database. BUT, in DigiX mode, the RX and TX gain is set not with the Mic and AF Gain, but with the RX/TX gain setting on the Setup-Audio-VAC tab. There may be times where you want different gain and TX bandwidth settings for feeding different digital mode programs or modes within the same program. Feature Request: Could there be a flag in the TX Profile database that indicates that the TX Profile is a digital mode profile and then have records to set the RX and TX gain like there is for regular modes along with the other TX profile settings? Obviously, if the TX bandwidth is fixed, this is basically a moot point. -Tim --- Tim Ellison mailto:[EMAIL PROTECTED] Integrated Technical Services http://www.itsco.com/ Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers
Re: [Flexradio] Feature Request: TX Profiles
Just to add one thing. It looks like the current TX profile does set the TX bandwidth based on some additional on air testing. Creating a 75 Hz TX filter for PSK31 actually improved my IMD based on the readings from the KK7UQ IMD meter and on air testing. So I want to augment my request to be able to store the two VARx RX filter settings in the digital operating profile as well. The fixed filters are not centered in the right place for SSB ASFK digital modes. Using the sliders makes crazy thing happen (but predictable). I have to continually manually enter the bandwidth min and max parameters. As an example, Id like to set a PSK31 Digital operating profile with a 50 Hz wide filter centered at 1500 Hz and a wider 200 Hz wide filter centered at 1500 Hz. Sitting on a frequency calling CQ and use the wider fixed filters for search and pounce operation. For RTTY, I'd need to use RX and TX different filter widths for that digital mode, hence the ability to have multiple digital mode profiles. The functionality is almost there. Just need to modify the TxProfile table in the PowerSDR.mdb a little bit and add the logic to handle the RX VARx filters and VAC RX and TX gain. This would making working digital modes real easy.

Re: [Flexradio] SSB audio question
There seems to me that there is a common theme floating around here concerning the buffer settings for optimal use. Since there also seems to be answers that are all over the spectrum (which is understandable due to the variables involved), maybe a more scientific approach is required Maybe what we need to do is collect some data from the users on the reflector on the processor used vs. buffer settings categorized by sound card. Plot the data with the processor/speed data on the X axis and the buffer settings data on the Y axis. Hopefully there will be some sort of correlation and the graph will have some sort of linearity. If it works, a nice little graphical representation could be useful for new users setting initial buffer setting values and experienced users to tweak their systems. I'd be willing to collect the data if enough people are interested. Just send it to me off-list I need the following data: 1.) Processor family/type and speed 2.) Type of sound card used 3.)

[Flexradio] CPU utilization video driver corruption with Preview 8
Eric, Here is an observation or two and not a necessarily a commentary on higher CPU utilization with DirectX In DirectX mode, I get a bunch of Unhandled Exception errors when using the GUI (clicking on buttons and such). If I click on the button to continue, CPU utilization goes from 25% to 3% I am beginning to think that once I receive an Unhandled Exception error, that the display parameter reverts from DirectX mode to GDI+. Could this be happening? The reason I am thinking this is that in GDI+ mode my CPU utilization is always 3-5%, but in DirectX mode (before the exception error) the utilization is 25%. After the exception error the utilization is 3%, but Setup still indicates that the display mode is DirectX. I have also found that getting a lot of these Unhandled Exception errors corrupts my video driver. This is indicated by CPU utilization running at 50% when nothing is loaded on the machine. ProcessExplorer from SysInternals indicates that these are all Deferred Procedure calls, indicative of corrupted software of bad hardware. They do not go away even after re-booting. There are no errors in the Event Viewer and the video looks OK after rebooting. It does take PowerSDR a LONG time to load in this state and it is very unstable. The only way to rectify the problem is to completely un-install and re-install the video driver. For now I am using GDI+ and don't have any complaints.
Re: [Flexradio] CPU utilization video driver corruption with Preview 8
OK. I can believe that once the DirectX stuff crashes, then it quits what it is doing. The display continues to work (for a little while), but it is very unstable. Eventually the exceptions will actually crash the entire application and that is when I get video (something?) corruption that so far only goes away when the driver is removed from the system. I am investigating my video adapter's report card on gamer sites to see if there are any observed issue with DirectX. BTW, the system rocks on GDI+. The new FFT seems faster and I really like the AGC improvements. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: FlexRadio - Eric [mailto:[EMAIL PROTECTED] Sent: Sunday, December 18, 2005 3:43 PM To: Tim Ellison Cc: FlexRadio@flex-radio.biz Subject: RE: CPU utilization video driver corruption with Preview 8 Wow. There is no way that I know of that would cause PowerSDR to automatically go from DirectX to GDI+ as you described. More likely, whatever is hanging up the DirectX stuff crashes upon subsequent calls and then it quits doing whatever it was doing before, thus freeing up the cycles. After this, I would be surprised if the display continues to work. Having DirectX corrupt your video driver sounds very strange. If a reboot doesn't fix it, then I'm not sure the driver/hardware is working correctly.

Re: [Flexradio] Set up
Have you tried measuring the voltage from the sound card? (Soundcard calibration test). I know you are not supposed to have to do it, but it sounds like (no pun intended) you are getting something on the line out of the sound card that shouldn't be there.

When I hit the MOX control even in SSB mode with no mic connected, I get as much as 120W on some bands. If I modulate with the mic connected the waveform on the screen goes higher but I don't see any more peak power. If I hit the MOX control in the CW mode I also get the same power out. I do not have anything plugged into the key jack at the present time, but the behavior was the same when I had a paddle plugged into the SDR. When I try to do the PA calibration, I can get it to come into spec on 160. When it gets to 80M I can't get the power below 110W. The power is lower on the remainder of the bands and 80M seems to be the most out of whack. When I try to reduce power using the PWR control there is no response.

[Flexradio] RF Output down 50% from preview7
I noticed earlier today that my forward power when transmitting on SSB was significantly lower with Preview 8 than with Preview 7. As a test, I ran Preview 7 and tested the RF watts out when I had voice peaks of 0 on the ALC meter. The SDR Forward Power meter showed peaks in the 90 watt range. This was verified on my watt meter as well. I deleted the database from preview 8 and restarted the application. I imported Preview 7's database with out any problems. I verified that the TX settings were the same between the two versions. When testing with Preview 8, the RF power out only registered about 30-40 watts with the exact same ALC values (peaking on 0). My watt meter also showed about a 50% decrease in power. I took great care to keep all the variables the same between the two test cases. I decided to violate Fett's Law so I shut down the radio and did some work that pays the bills and came back later to repeat my experiment. I got the same results. Would there have been an change in the TX audio chain that would have be responsible for this reduction in output power? -Tim --- Tim Ellison mailto:[EMAIL PROTECTED] Integrated Technical Services http://www.itsco.com/ Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers

I have been working in systems integration for almost 20 years. Even did some Windows C programming back a long time ago. I am not an EE and don't plan to play one on TV either. Am I the smartest guy on the block? Not by a long shot. Do I like working with the SDR-1000? You betcha!

Yea, you get wet sometimes riding the wave, but you're the one getting the girls - not the guys sitting on the beach :-) I can tell you that just about all the Xylo FPGA stuff was waaay over my head. But what I can gather, it is a doohickey that will do whiz bang hardware integration things real easily and some of the current projects might replace the soundcard and the parallel cable interface to the radio. Cool stuff, but it make my brain hurt, so I just delete the stuff when it come across (no offense to the Xylophiles). Even with some C programming background, the technical discussions about the source code is baffling as well. I even downloaded it and looked at it. It is definitely out of my league. Another great candidate for the Deleted Items folder. What I can do, is try to break things (beta testing). There is no advanced degree needed for that! Then I share my observations with the group and hope that some of the information helps make the SDR-1000 a better radio. I really like being part of the process. Riding the wave! Along the way I have picked up a thing or two about the operation of the radio and when I can will share that knowledge with those just getting into the water, which at first is a lot colder and wetter than sitting on the beach (but remember who gets the girls :-) ). The SDR is definitely a user supported radio. Since the computer is the radio (I stole that one from one of Sun's old adverts), there are going to be lots of computer questions as well. Bring em' on! There are a lot of smart folks lurking on this reflector and one of them *knows* the answer and will gladly pass it on. (try that calling Icom tech support with a toll call). And above all theSDR-1000 is a BLAST to use and everyone that knows I am using an SDR is always intrigued. Once they read my brag file on PSK, there is usually a long discussion on what is it really?, How do you run digital modes without a soundcard interface (I love that one) and usually ends up with a statement about how really cool that is. (that is the getting the girls part). I know someone somewhere said to one of their ham friends that he worked a guy on a SDR. I can also bet that he didn't say I worked a guy with a YaWoodCom from NC last night. So please, please don't get discouraged. It is all about having fun and enjoying your hobby.

Re: [Flexradio] SSB tests
Hi Bob Eric. OK. Here is what I did, just now to verify the reduced power with Preview 8. I was really careful about making sure nothing was different between the two setups. Using a database from Preview 7, I did a Reset All to reset the DB back to defaults. I re-ran the PA calibration. I then deleted the DB for Preview 8 and imported the one from Preview 7 so all the options were exactly the same. No values were changed. I set up an AF single tone generator set for 877 Hz and placed the mic in front of the speaker. Here are the results from Preview 7 ALC = -10.5 dB PowerSDR Forward PWR = 113 watts External Watt meter (not calibrated) = 105 watts Here are the results for Preview 8 ALC = -10.5 dB PowerSDR Forward PWR = 26 watts External Watt meter (not calibrated) = 21 watts This is a significant difference between the two versions.

[Flexradio] Change to floats in Preview 9
Eric Bob, Ignoring the EQ conundrum, the change to floats in Preview 9 has dropped my CPU utilization on RX to a range from 0.8% to 2.3% where 1.6% seems to be the average with the logger running too. Adding MixW to the mix (a pun!) drove it up to a whopping 6.0% to 8.3% where 7.0% seems to be the average. That is about a 60% decrease from Preview 7 and Preview 8. VERY NICE!

Re: [Flexradio] Setup for beginner help results
Chas, It is good to see you have things working with Preview7. I can understand your concern about software stability and usability. There is a stable version, 1.4.4 that can be used and is recommended to be used if you do not what to wrangle with a preview version. You don't get the latest features, but you also do not get the surprises that come along with beta software. One thing about the PowerSDR development cycle is that it is a lot more open than other software development efforts. In most other companies, the preview code is only released to a select handful of testers and the general public isn't informed of the new features of an upcoming release until it is released. The good folks at Flex Radio allows those who want to live on the edge to run a preview or beta through its paces. With a company as small as Flex Radio, it would be impossible to regression test all of the features on every kind of computer/soundcard/video card combination out there with the staff they have. That is what we who choose to use Preview versions are here for. By your own choice, you become part of the QA team by testing the previews. First Preview 9 has been very stable for me as long as the TX RX EQ is not used. The AGC and optimized FFT improvements alone is worth upgrading. Also another change with Preview 9 is that DigiU mode automatically sends the USB CAT command so that MixW is set for the correct mode (USB rather than FSK, or nothing) so the SDR1K and MixW are always in sync. You are correct that if VAC is engaged, you can not use the mic - the audio I/O is routed through VAC. On the VAC setup page, if you check the box Auto Enable, then when you select the DIDGU or DIGIL modes VAC is automatically engaged. When you are in a non-DigiX mode, VAC is disengaged so you can use the mic. If I could offer one hint on operating digital modes that I think will help some what and allow you to use a feature of the rig that (as far as I know) doesn't exist elsewhere. Highly Customized TX Filters. Once you have CAT working within MixW, you can do the following: First, I found that I can get more and much cleaner output (better readability) by using a TX filter that is about 2X wider than the digital mode I am using (100 Hz for PSK, 500 Hz for RTTY, ect..) To use the customized TX filter correctly, pick a center frequency, say 1500 Hz. Create the TX profile and set the TX filter so that 1500 Hz is dead center of the filter bandwidth. Then create a MixW macro called Align that has the command ALIGN:1500. Use this macro to place the TX frequency of the station you want to work in the middle of the TX passband. This ensures that you are always transmitting within the bounds of the TX filter. You can place the MixW decode cursor anywhere on the waterfall and if you want to transmit, just hit the ALIGN macro, the frequency of the SDR1K shifts to the proper location in the TX passband and away you go. If the MixW soundcard is set for full duplex, using the Panadapter, you can visually see that your TX signal is within the TX passband. I also set up a VAR filter on RX that is a little narrower than the TX filter (still centered at 1500 Hz) and will engage that to totally eliminate and QRM that is on either side of the frequency I am having my QSO on. This is real convenient when doing digital mode contesting. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charles Greene Sent: Monday, December 26, 2005 2:06 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Setup for beginner help results Hi, I have VAC and VCOM installed and working well. I take it that it is proper to turn VAC off in order to operate SSB from a mike. MixW CW and all digital modes work well, and my external keyer works well in parallel with keying CW with MixW from macros or from the keyboard Now to MMTTY. MMTTY does not work with my USB sound card and K2; it can't find the sound card. MixW has no problems. I am running PowerSDR Beta 1.4.5 pre 7 which seems pretty stable. I'll wait until another stable version comes along before upgrading. The only problem I have with pre 7 is that when operating with another program running, if the other program tries to access the sound card, whether I am using the default sound card or not, the Power console stops processing and I have to turn it off and then restart it. Otherwise, the power console will run all day. Pre 7 has a lot of features. I wish you software types would do some regression testing on pre 7 or something and get rid of the Beta. You need an advanced system for users who are not pushing the limits, or else you are going to lose some. As a software engineer for 20 years, I have found as others have, that when you add new features or correct old bugs, you need regression testing to make sure you did

[Flexradio] A question on Frequency stability vs. Temperature
I have a question about frequency stability of the SDR1K in regard to variable temperatures inside the SDR1K. The reason for concern is frequency drift while working digital modes. For the sake of this argument and staying on point, let's assume that the frequency delta is significant, although in reality it probably is insignificant. Some initial background information. I am seriously thinking about installing a temperature-proportional cooling fan speed controller in the SDR1K to further reduce fan noise. The controller is not designed to provide a stable temperature (thermostatically controlled), it just increases the fan's RPMs as the temperature increases until it reaches max RPMs @ 105 F. I assume that since the fan is not providing constant CFM air flow, under high duty cycle operation, there will be a more rapid rise in temperature until the fan is running at full speed, at which some level of temperature equilibrium is reached, as opposed to having the fan run at full speed all the time resulting in a temperature change that would be less drastic. The net effect is that the internal temperature will vary more with the fan controller therefore resulting in more drift in the XO. I am aware of the ability to use external precision clock sources to more precisely drive the DDS, but in my current configuration, the Valpey-Fisher VF-161 XO is utilized and is sensitive to frequency drift with changes in temperature. From the specs, the max temperature for the XO is 85 C and the stability is +/- 20 ppm. http://www.valpeyfisher.com/PDFs/vf161_E.pdf Assuming temperature stabilization is warranted, my question is this - what advantages / disadvantages would there be for trying to minimize temperature variations of the OX by adding some insulating material (Styrofoam maybe) around the XO or by adding an external precision crystal heater ( @ 40 C) to *stabilize* the temperature at a fixed value and hence the frequency drift? An example of the precision crystal heater is found here: http://www.kuhne-electronic.de/english/special/crystalheater.htm Any and all comments welcome.

Re: [Flexradio] Software taming the wandering oscillator - a thought

I have the PowerSDR mic gain set at 32 and that sees to give me 0 dB when the TX Meter is set to ALC. When you transmit, the processed signal has to get back to the rig. On the D44 Monitor you will see that in WavOut 3/4 with an output of -12 dB The other thing to check is if you have VAC installed, when it is enabled, it disrupts audio coming from the mic.

[Flexradio] Audio processing advice with the Presonus FireBox
I an considering getting the FireBox for some portable operations. Before making that purchase I wanted to inquire to those who have been using it and wanted to get some feedback. Since I haven't seen any posts related to the FireBox and it not working correctly, I'll assume that is the case. My question has to do with audio processing. I have always been told that for the optimal audio chain goes something like this: Mic-preamp-EQ-compressor/limiter-effects Now I don't plan on using all that type of processing, but I do like using an EQ and currently the PowerSDR EQ is currently being re-coded. Since the FireBox has a preamp for the two XLR inputs and there isn't anything like an effects loop, what options would I have for signal process pre-SDR1K? What would be the cons for EQing a signal before the preamp? I see where you can use VST plug-ins for QuBase. Has anyone done this and what were the results? -Tim --- Tim Ellison mailto:[EMAIL PROTECTED] Integrated Technical Services http://www.itsco.com/ Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers

Re: [Flexradio] DIP OCXO for SDR
Eric, The VF VCXO listed below has a max frequency at 200 MHz. The XO currently in use, the VF 161 has a max frequency of 300 MHz. Using a device at either end of its rated frequency may suffer from precision and/or accuracy errors. The Crystek is much closer, but the output is a sine wave rather than PECL(positive emitter coupled logic) which is the output of the current XO. I am not sure if this will make a difference or not with the devices being designed.

From my (and TAPR's) perspective, we want to do a Reflock-based design because it will have a broader use than just the SDR-1000. For example, with a 64MHz VCXO, it can work with the Ettus Research USRP software radio. I can also see it serving as an external clock for a sound card to eliminate that source of frequency uncertainty. So, I don't see any conflict at all between what we're doing and the other approaches. The one SDR1k specific item I'd like to see, whether TAPR produces it or Gerald does, is a civilized board that will plug into the reference oscillator socket to allow a better interface to an external signal. I've started looking into that and we'll work with Gerald to figure out how best to offer that. It's mainly a matter of finding a buffer/level converter chip that will take a single-ended input and convert it to a differential signal at the right level for the DDS chip (suggestions welcome; I've started researching the chipmaker sites, but haven't found an obvious answer yet). 73, John ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman

Re: [Flexradio] Possible problem on 1296 MHz
It is probably a problem with the database which is easily corrected. It has to do with overlapping frequency range records in the BandText table in the database. I checked in my database and it is OK. Using Microsoft Acce$$, open powersdr.mdb. Once opened select the table BandText. Towards the bottom, is the frequency ranges for 23 cm. There should be a continuity of frequency ranges starting at 1240 MHz going to 1300 MHz. Make sure there are not any records that have overlapping frequency ranges. This was a bug in previous versions and was fixed in on of the previews. You can also try this. Rename you existing database to something like poswesdr.mdb.sav, start up the preview version you saved the DB under and let it create a new database. Configure the transverter and other necessary parameters and then check to see if the frequency range is correct. If it is, you have two choices - use the newly created database and configure the rest of the parameters necessary for your operation including the calibration routines -OR- open up you existing database and do a little record surgery. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Marc Franco Sent: Tuesday, January 17, 2006 8:33 AM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Possible problem on 1296 MHz Hi all, I have tried to set up the beta Power SDR console 1.4.5 rev. 11 with my 1296 MHz transverter, and I noticed that it refuses to transmit at certain frequencies (i.e. above 1296.050) by complaining of being out of band.

Re: [Flexradio] Steady drop in output power with successive Previews.
Bob Eric, Bob, I tried the use of the CPDR with poor results. At the second lowest setting of the CPDR (2 db) the audio quality was degraded significantly introducing a lot of distortion. At the lowest setting, (1 db) the distortion was less, but still very prevalent. At these setting, there was no difference in RF power output between using CPDR and not. I did the same test using just the COMP and the results were similar, but I had to use higher values (4 2 dB respectively). Even at 1 dB there was still noticeable distortion. Using the TX EQ did help some, but I had to add a lot of gain to make a slight difference and adding that much gain resulted again in a distorted audio signal. So I tried some more testing... Using a PSK steady tone (carrier only), I set the output gain until I was showing 50 watts Peak and Avg. power output (1/2 of the rated value of the PA). I used this value to calibrate my non-peaking reading watt meter. I also verified this with a CW carrier and they were very close. With the MIC setting peaking at 0 dB, the RF output is just 20 watts. The Peak power meter showed a max peak of 46 watts. I have a true peak reading watt meter on order that should be here next week so I can more accurately measure RF output and I will run my test using it. I also did an on air test where I used Preview 7 and Preview 12 using the same configuration, only adjusting the MIC gain to give equal 0 dB on peak readings and was told that the Preview 7 was much stronger and didn't have any distortion on the audio signal (subjective opinion, of course). With Preview 12, the signal was much weaker and the observer couldn't tell any discernable difference in the audio quality other than to say both sounded very good, but because the preview 12 version was less strong, he couldn't give a honest opinion to if it was less over driven or not. I understand how SSB works and I don't expect to see 80-100 watts output continuously, but the behavior I expect is to see some peaks above 50 watts and a higher value for average power. I also understand your explanation concerning the AGC limiting the RF output and not wanting to over drive the PA, but when I can get 100 watts (and more) out on CW and PSK distortion free, 20 watts on SSB voice seems to me a little bit aggressive. Maybe the AGC is working too well. My testing methodology is the best I can do right now with the tools I have and if there is some flaw in my logic, I'd like to know so I can make the appropriate changes. I am very pleased with the changes made to the RX in this preview stream, but a four fold decrease in TX output from preview 7 to 12 is obviously not what I was expecting. I just don't have the antenna system to start working QRP :-) Do you have any suggestions for parameter I can work within the software that might elevate the low TX power issue that wouldn't adversely affect the RX quality? I'm not criticizing or complaining, just concerned that one of the features of the radio I expect to behave at a certain level is not.

[Flexradio] Behavior of PEAK HOLD in Preview 12
Eric, I have noticed that if I have PEAK HOLD turned on when I am using the Panadapter that if I change the frequency the peak signal that was displayed stays in the display just shifted by the value of the frequency change. Let me try to explain better with an example. Say I am listening to a quiet band, 14.300 and the signal is flat @ -130 dB. Now a strong signal is present at 14.300, so with the AVG and PEAK HOLD on I see a rise in the signal from 14.300 to 14303. If I move the VFO to 14.303, the 3 KHz rise in signal moves to the left of the center line in the panadapter. Now another strong signal at 14.303 to 14.306 is present. At this point with PEAK HOLD and AVG I now have displayed on my screen a 6 KHz wide increase in signal. This makes looking for signals much harder since if you change frequency the display stays cluttered with previous signal display. I suspect this is the way it works, but I think if you move the VFO you would want to erase the signal displayed by PEAK HOLD. In other words, if the VFO is changed, the display should be reset only if PEAK HOLD is engaged. This is the way my other radios that have a peak hold feature work. So, in a round about way I am asking for the current behavior of PEAK HOLD to be changed when the frequency changes. -Tim --- Tim Ellison mailto:[EMAIL PROTECTED] Integrated Technical Services http://www.itsco.com/ Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell PGP public key available at all public KeyServers

I chose AMD over a Pentium because it utilizes a crossbar switch for inter-core communication and the on-chip integrated memory controller rather than the front-side bus architecture to relay both memory and I/O traffic from the cores to the memory controller. In RX mode (v1.4.5p12) with Firefox, Citrix client, VCOM and VAC 3.11 running using the Delta 44 (PCI), my average processor utilization ranges from (a whopping) 2.1% to 7.8% (avg = 4.2%) I have seen it as low as 0.8% with nothing else running. In RX mode (v1.4.5p12) with Firefox, Citrix client, VCOM and VAC 3.11 running using the FireBox (Firewire), my average processor utilization ranges from 14.5% to 23.8% (avg = 17.5%) Both configurations were run on Win2003 (32-bit) and consume about 262 MB RAM. At these loads, I think you could run several instances of PowerSDR if you had the parallel ports and sound cards (and of course the DSR-1000s) at your disposal. Processing power is getting cheaper. And like Duane said, if I run out of CPU horsepower, I'll drop in a faster processor. Personally, the new features I am looking forward to are 96000 Hz sampling rates, GUI skins, Better DDS spur elimination routines, splitting the DSP and GUI functions (running on multiple threads), multiple receivers (in the passband), native digital voice modes, and any wiz bang audio processing goodies (VST plug-in support maybe) Eric and the group can think of. I throw down the gauntlet and challenge you to make my processor weep :-) -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Duane - N9DG Sent: Friday, February 03, 2006 10:23 PM To: 'FlexRadio Mailing List' Subject: Re: [Flexradio] Repost - Multiple SDRS one CPU Comments in line below: --- Mike King - KM0T [EMAIL PROTECTED] wrote: Eric and all, thanks for the comments. I think as discussed below, if your ultimate setup is using two Delta44 cards...(as I would like to have) the control panel handling two cards...I remember seeing that it could handle 4 devices. I guess one would not have to install the software again for the Delta 44! I'm still rooting for official company (and software) support for the Audiophile 192 running at its 80kHz sampling bandwidth here :)... (I *really* want that 160kHz panadapter). As I recall the two 192's showed up separately in both the M-Audio control panel and in PowerSDR such that you could select the one you wanted to use. If anyone installs two D44 cards and has two SDRs going, please post the results. I dont have a spare card right now to try. I did have two 192's installed at one point but never actually tried running two sessions of PowerSDR with them. May just have to try that this weekend. PS - Duane, have you benched the AMD processor with PowerSDR against an Intel P4 3.4 650 processor or similar? Is your AMD the dual core unit? I would think even the new Intel dual core processors would be excellent at this, as then there are 4 virtual processors. (Hyperthread X2) I have not done any benchmarking against anything else. It is a plain Jane AMD Athlon XP 3000+ and is not dual core. This AMD based machine has 1MB of RAM and is definitely not near the top for performance heap by today's standards, - even when I bought it wasn't. I always buy based on the best horsepower/$ point on the pricing curve. Even so in recent (last 8 month or so) versions of PowerSDR it has only been running at 15% CPU time total (driving it with VNC only bumps up the CPU usage a few percentage points. The RAM usage is very modest as well. Based on these observations and I my gut instinct tells me that running two sessions of PowerSDR the machine will not be CPU or RAM limited. Until of course that 160 kHz panadapter version comes out :)... If I don't have the horsepower at that point then I'll just buy more CPU horsepower ;) - after all it's the least expensive part of this radio. Duane N9DG __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [Flexradio] SSB Carrier suppression on Preview 12
Sure do. I just finished testing it on 20m USB with 1.4.5p12. If I have the TX set to 14.170 MHz and key the rig without modulating, I begin to hear an unsuppressed carrier on a separate receiver starting at 14.17000 MHz (barely audible) which increases in intensity and pitch until a peak at 14.16690 MHz (very audible). It does this with versions 1.4.5p7 and 1.4.4. Version 1.4.4 sounds louder than 1.4.5p7. The difference between 1.4.5p7 and 1.4.5p12 is too close to tell by ear. I have no way to test this with a scope, so these observations are at best approximations. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dudley Hurry Sent: Sunday, February 05, 2006 1:55 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] SSB Carrier suppression on Preview 12 SDR Gang, I have received several reports while running Preview 12 of unsuppressed carrier.

Re: [Flexradio] SSB Carrier suppression on Preview 12
Hey Jerry, I have both the monitoring and TX radio on dummy loads. As a check, I did the same test on my Pro II as I did with the SDR (using identical settings) and there is no carrier heard from the Pro II like there is on the SDR1000. I really believe the carrier is not being fully suppressed. -Tim --- Tim Ellison ( [EMAIL PROTECTED] ) Integrated Technical Services ( http://www.itsco.com ) -Original Message- From: Jerry [mailto:[EMAIL PROTECTED] Sent: Sunday, February 05, 2006 9:36 PM To: Tim Ellison Subject: Re: [Flexradio] SSB Carrier suppression on Preview 12 Hi Tim What S meter reading? It sounds as if the carrier is down many DB's. If there is any carrier it would blow out the front end of the monitoring radio. A fraction of a milliwatt would gove a S9++ signal. 73 de Jerry At 04:33 PM 2/5/2006 -0500, you wrote: Sure do. I just finished testing it on 20m USB with 1.4.5p12.
