[Flexradio] Poor sideband suppression
I'm getting poor opposite sideband suppression.Another Flex owner, Jeff, K6JCA, took a snapshot of my spectrum off the air and there is a significant hump on the opposite sideband. Other listeners have heard the opposite sideband. It's not DSB. It's maybe 30 dB down. The TX image alignment had very little effect. I performed the alignment with a receiver, not a spectrum analyzer. Where do I start? Here's the set-up: Used SDR 1000, age TBD but was on the air before I acquired it last week. Has the PA. New PreSonus Firebox, just got it from Flex (just before announcement of the FA-66 [EMAIL PROTECTED]) 48K sampling. Have not installed the beta firmware Cables from Flex, the HOSA cables Firewire to Compaq laptop, 1.3 GHz External (wall wart) power to Firebox Parallel cable, computer to radio 35A linear power supply to SDR1K 1.6.2 software One more thing. The output from the Firebox measures about 1.98V during the audio TEST, nothing like the 6.93 hardwired into the set-up form.

[Flexradio] on interfaces and modules
Here's an interesting question. Today, if you wanted to add a new modulation scheme to PowerSDR, it would involve recompiling (or at the minimum re-linking) and creating a new EXE file. But what should it be in the future? Consider a concept like "loadable IO drivers" or USB devices. You plug it in, and it works, and you don't have to recompile ALL your applications to make use of it. But even within this scheme there are two flavors: sometimes you have to reboot, sometimes you don't. In PowerSDR terms, you might have to exit and restart Power SDR, with other schemes, you might just start using it. And, then, once you have loadable "waveforms" (to use the SDR term of art).. what of the user interface... should the host program (PowerSDR or its successor) ask the new waveform module what the interface should be, and the waveform module tells the host how to "render" it? Or, should UIs be totally separated (distribution wise) from waveforms? Lots to think about. James Lux, P.E.

Re: [Flexradio] CW tests here
Bob I did some more work on this and found the issue was due to setting the DSP buffer to 4096 and having my DSP bandwidth to 48k. This made the buffer fill slower and hence the delay and chopiness I was experiencing. What seemed to be happening was as I momentarily changed from T to R the buffer would clear and then have to refill on the next dit with enough delay to screw up my rythm. Setting the buffer back to 2048 seems to have solved the problem. I also am using the D-44. It might be a good idea to describe somewhere the relationship between buffer setting and DSP bandwidth with regard to expected CW performance if that hasn't already been done. 73 __ Do You Yahoo!?

But not in the software radio business... For the straightforward "knob turning" kinds of controls, sure, there's a lot of experience to draw on. But, for instance, what should the interface be to define an arbitrary IF passband characteristic? complex weight vs frequency? Some parametric form? And, what should the "user interface" be vs what should the interface between UI and underlying radio engine be? It is unlikely that it should be the same. Consider the audio equalizer business... lots of competing schemes out there (although I believe for "pro" applications, they've probably settled on something). And then, say you want to support different modulation strategies for digital data.. should the abstraction be at the "define modulation in an analytical way" or "select from an enumerated list of canned schemes".. Consider something as simple as biphase modulation. Should you specify mod index and symbol rate? But how would you accomodate GMSK? What about the various COFDM schemes. Sure, today, hams use things like MFSK16 or Olivia, which implies a particular modulation scheme, but, once you've implemented the modem, you could paramterize it fairly easily (carrier spacing, mod indices, modulation order per carrier, etc.) Should this be exposed at the command interface? or, just embedded in a definition of the waveform. > Based on my background I have submitted many comments to Flex re > all that.

If that was the case, please don't tell my old boss.. hi hi I think the path is clearer for the UI end of things, but, still, sort of vague, when it comes to capabilities that have never been available... For instance, what's the optimum UI for a system where you have an adapative phased array that can null interferers? (or, similarly, where you've got an interference cancellation system). What about a radio/antenna system where you have control over both azimuth and elevation should the interface ask you to select a "look angle"? or, at a higher level of abstraction, a "target location" (rolling in some estimate of propagation) I think we're just starting to poke at what's possible. Consider all the "point at signal on spectrum analyzer" kind of interfaces. There's a pretty wide variety in the PSK31 world.. Heck, do you prefer waterfall scrolling horizontally or vertically? What about 3-D waterfall displays with signal amplitude shown as vertical displacement from a virtual plane tilted. ___ 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
Re: [Flexradio] CW timing changes
I figured out what is going on. I had checked 4096 on the DSP buffer and only 48K on the soundcard so the buffer was taking a long time to fill/purge on TX/RX transition. Setting the buffer back to 2048 resolved the problem. I mention this so others that may experience this problem can find a resolution. 73 W9OY __ Do You Yahoo!? Tired of spam? Yahoo!

This is a generic problem with software based platforms. It basically gives you an incredibly flexible and spacious canvas and a big, big box of paints and brushes, but there's still a lot of work to implement a features. It's not so much that any one feature is particularly difficult, it's that there's literally dozens and dozens of particular features that might be implemented, and not enough worker bees to implement them all. Not to mention that most of the worker bees are doing it for love, not money, so they tend to work on features that are personally interesting to them. Unless you're a big mfr with a big R&D budget where you can pay people to work on particular features, you sort of have to take what you can get. For myself, I'd like to see cleaner, well-documented control, data, and audio interfaces that allow one to use the full power of the underlying engines (i.e. CAT is fine if you want to emulate a standard radio, but doesn't give one much scope for spectral displays, fancy filter specifications, etc.). As far as CW performance goes, I'd be happy with a couple of bare wires that get touched together, since I don't use that mode, so, to my mind, precious volunteer development resources expended there are a waste. However, I realize that I'm in the minority here, so I content myself with ranting about it every 6 months or so, and let the product evolve in its own way. There IS a lot of cool stuff, and to a certain extent, software radios, in general, are so new that NOBODY knows how to best control, interface, and use them (some commercial/govt implementations of SDR are so wonderfully abstract and generalized that they are totally impractical to use). Interface design and conceptual architectures are a matter of experimentation. With the SDR-1000 and PowerSDR at least that experimentation is possible.. A lot easier than machining a new front panel and buying new knobs and displays, laying out PC boards, or burning PROMs every time you get a new idea to try out.

[Flexradio] CW tests here
After the reports of worsened CW keyer response I got on the air and did some QSO's. I don't see one iota of evidence that the keyer has degraded in my set up. It is important to set the latency setting parameters correctly to use CW. First, if you are using a Firebox make sure that your latency is 10ms or less. Start at 10ms. Set your audio buffers to on the setup tab to 512. Setup->Audio-> Buffer Size. I had several QSO's at 35-40 wpm and I cannot find any degradation in the performance of the keyer, the switching, etc. I am using the Delta 44 and that might be different from what most are using that are having the problem. I can't say. All I can say is that sitting here operating, I see nothing different at all. The other factor is that I do not use the parallel port keying (the key jack on the physical radio). I use a serial port connection for my paddle. I suspect that almost everyone who is getting good (excellent in my case) performance is using the serial port. I hope these instructions help and I am sorry that I am unable to reproduce or confirm your findings. I would work on it if I could. Bob -- AMSAT VP Engineering.

Tha fact is, I want to like the SDR1000 and, whilst I was using what was sold as a kit and work in progress I did give more than I have done since buying the latest unit. Whilst it now appears than my TX trouble was probably due to having the headphones plugged into the soundcard, which no one ever told me should not be done, the new unit is advertised alongside other commercial offerings and in no way is there a suggestion that the SDR1000 should fall short of other radios that cost similar amounts. If you were to buy a Yaesu/Kenwood/Icom for the same money as the SDR1000 now costs, would you accept that you needed another keyer? 20 years ago, maybe, but surely not now? If the pre-amp switched on and off as you tuned the radio, would that be OK? especially if other people with the same radio said their radio did not do this? That would probably be taken as evidence of a fault with the particular radio, and not, as seems to be the case here, as a sign that the radio is not faulty. I'm sorry, but if Flex-radio want to be main stream, and advertise and sell alongside the other main radios, as their agent in the UK now does, then at least the base model has to work in a similar way to the other radios in the same price range, in my opinion. Otherwise, you should make it clear that the radio has faults, or is not fully functioning when you sell it... I do buy QRP kits, and I accept the limitations, they cost less and are sold and advertised as QRP kits, not fully functioning commercial quality radios.

Re: [Flexradio] Iambic Keyer
Hello Dave, John beat me to it, but I'll still pass along my comments and a suggestion. I've been using the SDR-1000 for almost 2 years now on cw. Although I'm not certain, I believe that the SDR1K keyer is Iambic mode B. I've been a cw op for over 40 years now, and I have strong opinions about what 'feels' right to me regarding keyers. I have three radios - all with perfectly fine keyers -- an Elecraft K2, an ICOM 746PRO, and the SDR-1000, and although I can use the built-in keyers on all of them, my preference is for my trusty external Logikey K-3. It's not better than the rest -- it's just that I like the way it feels. So, I made the decision a long time ago to use an external keyer that I'm comfortable with on all radios so that I don't need to get accustomed to the subtle differences between them. This has worked very well for me. The K1EL keyer which John suggested is very inexpensive, and I'm sure you'd be able to find a mode that is comfortable for you. I now use the SDR-1000 exclusively; nothing else that I have -- or have ever heard (I live about 2 miles from AES - Cleveland, so I've pretty much heard 'em all) comes even close to the performance of the SDR-1000's receive capabilities, especially when it comes to cw operation. The SDR-1000's keyer actually works very well -- if you're accustomed to iambic mode 'B'. But, it sounds like you're a mode 'A' op, so of course the timing will be different, and you'll have a tough time trying to send decent code. IMHO, considering the incredible performance of the SDR-1000, you'd be doing yourself a serious disservice by giving up when you could just use an external keyer. 73, Dale WA8SRA David Ackrill wrote: >N3WT wrote: > > >>Dave >> >>May I suggest using an external keyer.

Re: [Flexradio] Iambic Keyer
For many months I used an external electronic keyer with its own monitor and turned the monitor on the SDR-1000 off. Worked fine. Then the software guys improved the Iambic keyer, so I put the external keyer away. Looks like I will need to bring it back until the SDR-1000 keyer gets fixed again.

I have used external CW keyers in the past, but ever since my TS850S I've been able to use a half decent internal keyer. For the cost of a TS2000, which I'm told allows both Iambic modes, this shouldn't be a case of buying another keyer, should it? I'm not asking for weighting and the rest (although most rigs half the price of the SDR1000 have them) but just to be able to send CW with my paddles isn't too much to ask, is it? It seems that so much is available from software, except a CW keyer...

[Flexradio] CW timing changes
I have noticed some timing changes in the CW behavior of the radio with the latest few SVN releases. What I am experiencing is a period between tx going to rx, the rx has a longer period before it becomes active that is longer than in older versions. It seems unrelated to how much delay is set by the semi breakin, though I have not tested extreme long delays. Also I can make the transmitter fault if I try to transmit during during this inactive period. For example if I am transmitting in semi-breakin, and the transmitter falls out between 2 words and then tries to pick up again the transmitter will either miss a dit or it will transmit the dit late, which messes up a the rythm of sending. The rest of my setup has been static and was working perfectly prior to the last few iterations of the SVN, however I did redo the database and recalibrate recently, so I don't know if its the change in my db or change in the code.

Re: [Flexradio] Using a Steppir with the Flex
It would be pretty easy to integrate this functionality into PowerSDR. Along with vCOM it will allow you to run CAT to any/multiple of the virtual or hardware com ports on the system as well as do CAT between computers over the network. I had a checkbox to allow you to designate which com ports only 'listened' on the CAT line and which one had control. With the bridge you would have to run multiple instances to cross connect more than two com ports at a time, but this could be extended to as many com ports that are available on the computer where the bridge is running. I used it with HRD controlling and MixW listening and logging at the same time before my SDR-1000 PIO board started giving me fits. 73 de Phil N8VB On 9/23/06, Tim Ellison <[EMAIL PROTECTED]> wrote: > I have seen a rig run multiple devices, but all of then were Icom CI-V > (TTL) using the CT-17 (CI-V bus) and the radio was in "CI-V transceiver" > mode. > > I'd REALLY like to see Phil's TCP->Serial Bridge or something analogous > included in the new version of CAT.

It doesn't seem to matter if I use CWL or LSB either. The frequencies, going up, are as follows (in MHz) 1.814 1.839 1.850 1.857 1.860 1.863 then OK up to the top of the band 3.500 3.512 3.517 3.520 3.524 Then OK Going down as follows 3.525 3.523 3.520 3.514 3.502 1.862 1.859 1.853 1.841 1.817 Anyone any idea what might cause this strange behaviour of the pre-amp and does it affect anyone else?

[Flexradio] Pre-amp switches itself off
The preamp on my new SDR1000 seems to be behaving strangely. As I tune up or down a band the preamp is as per the front panel setting. Then, at some point as I tune, it switches itself off (there's a click inside the box when it happens). The setting for the pre-amp on the display on the console doesn't alter, but the signals in the panadapter and all received signal indications drop down. If I switch off the pre-amp, and then switch it back on again, all is OK for a while. Then it turns itself off again and I have to reset it. Each time I turn the pre-amp on there's a click in the box and each time it switches itself off there is another click. I'm using CWL and it happens within the Amateur bands and there doesn't seem to be a correlation between the frequency that it happens on. I've noticed the effect in 160, 80 and 40 metres. I am tuning using a mouse wheel. This happens in V1.6.2 as well as the latest svn versions. I'll keep a bit of a log of the frequencies and bands, to see if there is actually a pattern to the effect. ___ 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
Re: [Flexradio] DC/DC Converter (DC1) Replaced with Linear Supply
Like I've said many times before(personal opinion).It's not a rig for everyone. Take my advice now and sell. You boat anchor needs you.
