[Flexradio] Keyboard Map for F3K ATU Tune?
Is there a keyboard map key to make the Flex 3000 ATU tune? I have a button on my mouse which was assigned ALT+ T' which worked fine with my MFJ 993, but with the new improved ATU code I think I can retire the 993. So, I need a key which will toggle the equivalent of the GUI ATU button. 73 - Mike W0STB ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/
[Flexradio] 400-500KHz filter?
Listening for NDB sounds interesting. Can anyone point me to info on building or buying the 400-500KHz lowpass filters that have been mentioned? Also, before I explore too far, would there be anything inherent in the Flex 3000 that would prevent it from hearing these signals?

They are different, way different. You use them for completely different things. Probably the first thing to do is to read the article that was written on the topic of AGC Threshold (AGC-T) and placed in the knowledge base at: http://kc.flex-radio.com/KnowledgebaseArticle50153.aspx That covers how best to use the AGC-T control. For instance, is changing the preamp from off to Pre1 doing the same thing as raising the AGC-T setting some set amount? No. What is the recommendation for improving copy of a weak signal? Is it to turn up the Pre amp setting, or too turn up AGC-T? It depends on the level of atmospheric noise being received. From input from the list here I have gotten very wary of ever turning up the AGC-T setting past 70 or 75 - maybe that's just an unfounded fear - LOL! Definitely. I am trying to think of when I ever set AGC-T below about 80 but then, I don't seem to use it the same way as others since I want the noise to be audible. Think of the AGC Threshold (AGC-T) control more of an RF gain control. You can use it to turn down the sensitivity of the receiver. The preamp is able to actually increase the sensitivity of the receiver. You need to understand two key things: 1. the relationship between the internal noise of the receiver and the external noise being picked up by the antenna; 2. the job of AGC to reduce the gain of the receiver so that very strong signals appear to be about the same level as a weak signal. What is not always obvious is the relationship between the two and that is probably why you are asking this question. Perhaps the first thing to do to understand all this is to understand the relationship between the receiver's internal noise (noise figure) and noise picked up by the antenna. This is easy to do if you try a simple experiment. Connect your receiver to a dummy load, turn off the preamp, and adjust the panadaptor to show -145dBm on the bottom. Select 20m USB and set the filter to 2.7kHz. At this point the S-meter should be showing about -110 dBm. That represents that equivalent noise power of the receiver. Basically, until a signal reaches that power level you aren't going to hear it. Now turn on the preamp. Notice that the noise power level drops to about -123 dBm. This is the new noise floor. The preamp's noise now dominates the system noise as opposed to the noise in the rest of the receiver chain. This means that the receiver can now hear a 2.7 kHz wide signal that is at -123 dBm, about a 13dB improvement over the receiver without the preamp. Notice also that we haven't even touched the AGC-threshold control. One more thing before we go on, try changing the filter width. You will notice that when you double the filter bandwidth the S-meter shows a 3dB increase in noise. That is because twice the bandwidth admits twice the noise power (given equal noise power per Hz). You may also notice that the noise level reported by the panadaptor is much less than the noise reported by the S-meter. That is because the panadaptor use a series of very narrow filters (FFT bins) to make up the measurement. If you set the filter width to the same as the FFT bin width then both the panadaptor and the S-meter would show the same noise power. Turn the preamp back off. Switch from the dummy load to the antenna. You may notice that the noise level does not increase very much. (You can look at the panadaptor if you like.) If it doesn't increase at all that means that the noise generated by the receiver is greater than the noise and signal being picked up by the antenna. It also means that you might not hear a signal right at the noise level. Now repeat the same test with the preamp on. Notice that there is a noticeable increase in noise floor when you connect and disconnect the antenna. Now you know that the system noise is being dominated by received noise. Your receiver will now hear any signal that is hearable. On my Flex 5000 with the noise at my location on 20m, the noise level typically rises about 3dB when I connect the antenna with the preamp turned off. That means that the noise contributed by the antenna is about equal to the noise in the receiver. I would probably get a little improvement from the preamp (but not much). Once I get to 15m and above, the preamp is needed in order to hear the minimum discernible signal. I've notice that changing the preamp setting does not change the levels I

Thanks to everyone who responded to my question. I did the experiments with the dummy load, etc - that was really interesting and fun.

I know the SR button stands for Spur Reduction, but I'm not certain what that means in practical terms. Is a spur like an image signal?

Is a spur like an image signal? Not really. The local oscillator (VFO) is a DDS oscillator that is programmed to generate a certain frequency. Normally the Flex uses an IF frequency of 9kHz. So if you want to receive a signal at 14,009 kHz normally the VFO would generate 14,000 kHz. 14,000 kHz when mixed with 14,009 kHz produces the IF at 9kHz. But sometimes a programmed value in the DDS VFO produces an internal divisor that results in not only the desired output but one or more additional low-level spurious outputs (spurs). Flex has identified which values do this and change the behavior of the radio slightly. If the DDS VFO were to produce spurs at a VFO frequency of 14,000kHz but not at 13,999 kHz then PowerSDR commands the radio to use 13,999kHz for the VFO frequency but then changes the IF to 10kHz. Now 14,009kHz - 13,999 kHz = 10kHz. So, in short, PowerSDR changes both the VFO frequency and the IF frequency behind the scenes so that the spurs do not show up. Pretty clever those Flexians. What got me thinking about this is the fact that CW Skimmer wants this to be turned off. I can see that Skimmer sees things differently with it on or off, but I don't know why that is. It is because of the magic hand-waving above. CW Skimmer always uses the same IF so the DDS VFO *must* produce the expected frequency or the frequency calculated in CW Skimmer would be incorrect. Also - is this something that has to do with receive only? No, this is done for transmit as well. What's really on my mind is - when I stop using Skimmer is it very important that I turn SR back on? Yes. It not only avoids spurs but it makes tuning much faster because PowerSDR doesn't need to change the frequency of the VFO for every 1Hz of frequency change. -- 73 de Brian, WB6RQN/J79BPL ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/ Message delivered to arch...@mail-archive.com

[Flexradio] slightly off topic Flex-wise...
Hello all, I've been playing with an enjoying CW Skimmer. But I can't get the telnet export feature to work with HRD. I am running the current versions of both (Skimmer 1.5 and HRD 5.0 2356) - I can define a cluster spot, HRD successfully connects and I can see info in the show console mode, but when I switch to Show Spots vs. console nothing is ever shown. In console mode there are many instances of Unknown command: showing. I do see what look like good call/freq/time entries in the console, they just aren't making it into the show spots mode. HRD has a note in the cluster configuration section saying it only works with DX Spider or CC Cluster, so I'm thinking that what Skimmer puts out isn't compatible. Or maybe I just don't have things configured correctly. If anyone can help I'd appreciate it!

[Flexradio] NR Info
A few folks had asked some specifics on the noise reduction unit - I answered off the list so I'll repeat the info here. The unit I have is a : bhi Ltd. NOISE AWAY Amplified DSP Module (ANEM) it is a little plastic box with power, audio in, audio out jacks, and a power and a function push button. I bought it from www.w4rt.com for $179. I think bhi makes a little nicer unit with level controls and whatnot - I'd probably go with that if I had to do it again. No biggie though. I downloaded the current manual from http://www.bhi-ltd.com/ - the instructions that came with the unit were way out of date. I am feeding it audio from the FlexWire line-out pin. The level was too low for what the box expected, but the new manual details how to cut the leg on a resister and adjust the levels inside the little box. After doing that all is FB. Several folks have replied to me describing the settings they are using for PSDR NR - it is interesting that they are all over the map! My feeling is that this little box does what a software defined noise reducer should do - it makes all those adjustments for you. Why should I have to mess with fidgety combinations of three different variables? What I'd like is just noise reduction. Yes, I want to be a noise reduction appliance operator. Press a button and the noise is gone. And that is what this little gizmo delivers.

[Flexradio] Be careful with your cables
I just got my Flex 3000 back from being repaired. Here's a tip I'll pass along. With enough effort you CAN plug the firewire cable in upside down. My particular setup has very limited room between the back of the radio and the wall, and sure enough, during a 3am session of trying to chase down RFI in a new computer setup I did exactly that. Just a little too much wiggling and pressure and not paying attention. This is a VERY BAD thing to do! It blows out a chip on the radio and it also blew out my firewire card. You'd think from looking at the shape of the thing that it couldn't be done but trust me, it can be done and it is a total bummer to do! Best regards, 73, Merry Christmas!

[Flexradio] Noise reduction - wow!
I have been fiddling and messing around with the NR button on PSDR since July, and have never been able to get it to reduce noise at all. I was told that it needed to listen and learn about the signals for a while, so I went to experimenting with making a little change to one of the three settings, letting it sit for a few minutes, change, learn, etc. All I ever got was various levels of distortion. My opinion is it is 100% useless. I was just about convinced that noise reduction was a myth, but friends on the air with non-SDR rigs seemed to have various levels of success - none of them had the total failure that I had. Hmmm - stuff like this is supposed to be just a software issue. Well - I now know that noise reduction IS possible. I know because I bought a Bhi Noise Away module which does audio DSP. And it does work! More like noise elimination. I'm feeding it with the FlexWire line out, and it is AMAZING. I did have to download the latest manual, clip a resistor because of the audio level, and tweak the input and output level pots. From then on it's just a matter of picking what level of noise reduction.pps noise elimination I want and I'm in noise-free nirvana! I'm actually worried that I might wear out the switch popping it in and out of circuit - it is just so fun to listen to the noise just vanish! I didn't notice what the chip they use in there is. But my understanding is it's just doing some math on some digitized audio.no magic or anything proprietary involved. Just some awesome programming I guess. Way to go, Bhi. So - it can be done. Maybe someday PSDR will do it. Until then this is the best $180 accessory I have found. The audio examples on their web site sound too good to be true, you'd swear they are faked or fudged some way or another. They aren't.

Re: [Flexradio] compare with PSDR NB?
OK - I have been looking at the two things as both being something that can eliminate noise. I guess that is too simple of an outlook. I'm not a noise scientist and so I didn't know that sometimes some kinds of noise need blanking and other kinds need cancelling. And I have no idea how to tell which kind of noise needs what. I don't know what kind of noise I have at my QTH so I don't know if I need a blanker or a canceller. Or both. I was hoping that by seeing and hearing a video I could see how the two compared. But apparently wanting to see and hear a comparison of these two things is a very bad thing to wish for - so I will be sure to just live with the noise that I have, knowing that there is not an answer to the question of how the MFJ unit compares to the PSDR NB button.

The NB function in PowerSDR is a noise blanker. The MFJ box is a noise canceler. They both have one function - to minimize or eliminate noise. Sort of. Let me give you an analogy. Your question appears to me something like asking, which is better, a dipole or a vertical antenna? They are both designed to transmit and receive radio waves so which one is better? I think that you will agree that, because they work in a different manner that there will be occasions where a dipole will be superior to a vertical and vice-versa. Are you doing NVIS or DX? Is the signal vertically or horizontally polarized? Unless I have the parameters of your application, I can't give you a meaningful answer. So, I believe that it is not possible to answer your question in a simple A/B or yes/no fashion. They are different and will perform differently in different situations. If the noise problem you are trying to solve is multiple sources of impulse noise, e.g ignition noise, then the NB function will perform better. If the problem is a single CW noise source, e.g. noise from a bad power supply, the NB won't work at all and the MFJ unit will work better.

[Flexradio] VFO B with mouse wheel?
Helo all, Is there any way to control which VFO gets tuned by the mouse wheel when in MultiRX mode? As near as I can tell by experimenting is when in multiRX mode the mouse wheel moves VFO A, and moves the Panadapter display, but VFO B actually stays put and does not move. I'm wondering if holding down a special key while working the scroll wheel is the secret?

[Flexradio] VR Mouse
Hi Pierce, I downloaded the latest version (4.80.103) of the Logitec SetPoint utility and just used that. Have the Flex keyboard map spreadsheet handy. For the basic button definitions just select the button you want to program with the Select Button tab. A menu will pop up at the bottom where you can select what program you are programming for - you can have different settings for all your different programs. Add PowerSDR into the choice of programs, then select the button you want to change, under Select Task choose Keystroke Assignment and a Specify Keystroke window appears. Just press the key or key combination you want and it gets entered right in for you. It is way easier to actually do than it is to describe it! It took me a few tries to get the up or down directions right, but all in all it is very easy to do. Aside from the page to define all the buttons there are pages to define how fast it scrolls, and how the free-wheel function works. That is a pretty neat thing - I have mine set up so if you just gently roll the scroll wheel it has slight little clicks or detents, but if you give it a harder spin it automatically unlocks the detent mechanism and free wheels. Then when it slows down to a stop, or if you stop it manually the detent thing clicks back in. Very neat! Have fun! Best Regards, Michael Jones W0STB www.scsitoolbox.com Michael: I have the VR mouse on order. Mind telling us how your programmed it?

[Flexradio] FireWire cable and more mouse gushing
I thought I'd share my experience recently concerning what difference the firewire cable can make in a Flex setup. I've gotten my famous cheap ($165) PC all settled in, and part of my process of locking things down was I decided to replace my Flex-supplied firewire cable with the best and shortest one I could get from Granite Digital. I got their super shielded 18 cable. And it makes a difference! I can run smaller buffers in the driver settings and PSDR Auido-Primary settings. And I can run larger DSP receive buffer sizes too - the occasionally stuttering that I used to have is GONE with this new cable. Who'da thunk it? Get the best and shortest firewire cable you can. Also, I used yesterdays list mention of the keyboard - Flex function mapping to finish up my VX Revolution mouse setup. Now when I am focused on PSDR the mouse functions like this: -Scroll wheel - normal, but with a slightly fast flip it switches to free-wheel smooth mode - Nice! Just like spinning the big old weighted knob on an old radio. -Scroll wheel tilt right/left - bumps my frequency 10KHz number up or down -Button right behind the scroll wheel - toggles PSDR Tune mode on and off -Horizontal scroll wheel - adjusts AGC-T up and down -Horizontal scroll wheel push - mute and un mute audio -Two buttons behind the horizontal scroll wheel - bumps filter width up and down Of course if I change my mind about how I want things to work it's no problem to change it to perfection. Again - who needs knobs? I can do about 95% of what I do with the radio now without moving the mouse to the gui and clicking here and there. Since it's programmable per executable all of the functions do the different things that I want when I'm in Firefox or Outlook. Very cool device, and very cool that the Flex can be controlled so much via keyboard strokes.

[Flexradio] splatter
It sure is enlightening to see the signals on the band using PanaFall.Some signals are beautiful, nice clean edges, taking up just exactly the spectrum that they should. OTOH - seeing a SSB signal - not an ESSB on either! - that has 2-3K worth of splatter on both side is sure interesting. I see some CW signals that have the same horrible splatter, as visible as the day is long. I think my casual investigation is showing that the worst offenders always seem to be the Big DX Guns - probably driving an amp until is screams. I always try to listen to these stations to hear what their rig is - so I'll know to be sure to never get one of them- LOL! Really, I feel like taking screen-shots of some of these signals and emailing them to their owners.

[Flexradio] new mouse
I had seen mention of the Logitec MX Revolution mouse here previously and was interested in its free-wheel mouse-wheel option. I had tried a Space Navigator for a few days and just couldn't make peace with it and so sent it back. But this MX Revolution is a keeper. The mouse wheel has two modes, the normal click step mode plus a free-wheel mode where you can just spin it and it will accelerate and then gradually slow down. Very nice for mimicking the knob-spin of an old style radio. Then there are a ton of other programmable button and axis options. Here's a list: 1. The two-mode vertical scroll wheel - described above 2. The same scroll wheel has a two-axis right-left tilt. I assign this to bump my frequency up or down by 10KHz. It's user-definable 3. Right behind the main scroll wheel is another programmable button. I haven't made up my mind what to use this for yet 4. Of course there are the normal right and left click buttons 5. Right behind where your thumb rests are two more buttons - I use these to bump up or down the filter bandwidth 6. Right where your thumb rests is another horizontal scroll wheel. I use this one for volume up/down 7. The horizontal scroll wheel can be pushed in - I use that function for volume mute. It's a pretty good sized mouse, it fits my hand nicely. All of the buttons and wheels are user definable so you can play with it to your hearts content to control any of the PSDR functions that have a keyboard key mapped to them.

[Flexradio] My new cheap computer has arrived...
The $165 machine showed up this afternoon. Here's a link where you can see the gory details, the bottom line is it's a 3.2GHz P4, all the usual computer stuff, and includes an XP Pro license. http://www.surpluscomputers.com/348774/hp-dc7600-p4-3.2ghz-1gb.html They messed up and shipped me a 512M RAM unit instead of the 1GB that I ordered - more later on this. The bottom line - it worked first time, like a champ! I put in a low-profile TI-chip firewire card (the system has two free PCI slots and 1 PCIe-1 and 1 PCIe-8 slot - all low profile), applied the MS firewire hotfix, installed the Flex driver, installed .Net 3.5 - and brought up PowerSDR 1.19.1 svn 3345. And it worked. I'm running with smaller buffer sizes on both the driver and the audio settings, and I can run with higher DSP buffers than I could on my Atom 330 box. The standare Flex driver settings worked FB right out of the box. I tried my worst-case test of settings of turning on NR, both NB's, ANF, everything, and there is no stuttering, just no problem at all. I also installed the other ham software that I want to use - Ham Radio Deluxe - the current beta version. Running that, the HRD logger (which seems to be a resource hog) and DM780 using VAC - everything runs just fine. My CPU usage percentage seems to hover between 18% and 30%. I set the CPU affinity to let PSDR have any CPU it wants, and on this box I've set up all my other apps to only use CPU1. I don't know how necessary or effective that is but I figured it can't hurt. And none of the other apps locked down to the second CPU seem to care or be slow or laggy at all. Oh yeah, I also put in my USB VGA adapter so I can have two monitors. It is a bit of a resource sink but it runs just fine. It generates a bunch of hash on 17 meters but ferrites fixed that right up. What surprised me was that with only 512M of RAM and all the above running - plus Firefox with 5 or 6 tabs open - I still have 100M of RAM free and the system isn't paging! They're going to send me the missing 512M stick. I could probably get email up and running on it as well if I felt the urge. So I think that's pretty good. Cheap, easy - just what the doctor ordered.

That will help but I suspect there are also several development efforts underway which will increase the CPU and I/O load. Then there's the users, who figure out new ways to eat computer power. E.G., I've been learning digital modes, and it's nice to be able to see many simultaneous transmissions decoded (I'm using HRD). Hmmm, PSDR has multi-rx, but limited to two channels. Works well for audio - we only have two ears. But for digital, Why not 6 or 10? Wow, if PSDR did that, I could have 6 channels being decoded simultaneously, each with a narrow filter, and 6 separate AGCs and DSP chains optimizing the processing for each signal however strong or weak it is, and notching other nearby signals away. As we continue to break out of the pattern of SDRs that mimic the capabilities, and limitations, of traditional knobs-and-switches radios, there's lots of things that will consume more computer power. This is A Good Thing. So, I'll be happy to junk my current PC in a year or two when I need (want) a more powerful one to go with PowerSDR 3.1.12!

[Flexradio] EQ'ing in the PC
I had asked earlier about the PSDR transmit EQ - whether it works on audio coming in from the PC via VAC -and I think I've determined that it does. But - I'd like to be able to apply more audio processing than that. So my next question is - has anyone got a way that audio coming from a good microphone into the PC can be processed in the PC (EQ, compression, etc) and have that processed audio sent out to the Flex via PSDR-Audio-VAC? I thought maybe something like using a program such as Audacity to apply processing to the audio and using the monitor function would work but that doesn't seem to do it - it seems like the audio processing is only applied to the tracks after they've been recorded. What I'm looking for is an audio program that would do the processing in real-time, not record it but just take input from the microphone, apply processing, then put it back out - perhaps to the other VAC program, which could then be grabbed by the PSDR VAC. I think my description is way more confusing than it should be! I would just like to process my microphone audio before sending it over to the Flex.

Maybe he's going to write an article on How I assembled a multi-op station for free Please publish this to the list - this guy is a con.

Re: [Flexradio] Juan - K4LCD - a con man
He says he's got a Flex 1000. It's not like he doesn't have a way to get on the air and enjoy his hobby. I just upgraded my shack from an old Yaesu 817 to a Flex 3000. By doing the normal method of scrimping and saving. I wasn't aware that posting to every ham forum until I get contributions was an acceptable method for upgrading. I see the ads in QST where you can contribute old ham gear that will get distributed to people who have NO rig. This seems to make sense to me - help get a new ham with no radio on the air. But an upgrade - just cuz there is something new available? Come on.
