[Flexradio] Re-Knob Tuning
Note heading change, as this is no longer anything to do with speakers. I have completely disabled keyboard shortcuts, as I find that, when I have several apps open at once (eg logger, chat window) I am forever forgetting to change focus. I start typing, only to find that PowerSDR had focus, and has suddenly done something I didn't want - irritating in the extreme. I had a shaft encoder from a much older project, which has a heavy wheel and can be spun. I have modified an old mouse and interfaced the shaft encoder with the old mouse wheel circuit. That part works fine, but I find that PowerSDR can't keep up with the pulse rate, and the PC beeps at me if I spin the wheel too fast. (I wish someone would fix that) So I am back to dragging the pan display for large changes and using the knob for small ones. Nothing gained over the original mouse wheel, really! Greg ZL3IX N4PY2 wrote: Brian, I have solved this problem with a mouse wheel that is the type that is weighted and spins. I have a logitech MX620 mouse that works very well in this application.

Like many, when I bought my SDR-1000, I was nervous about not having a VFO knob, so I bought the Griffin PowerMate. I quickly found that I did not like using the PowerMate for frequency change. This is an interesting example of how a tiny change in user-interface can make a huge difference in usability. I too like a VFO knob. It is actually a very natural way to change frequency and everyone is very comfortable using it. On other radios it works very well. Older radios with analog VFOs have a much faster tuning rate so that one can use the finger dimple and quickly QSY from one end of the band to the other. Once you get near the desired frequency, the fact that the VFO is analog means that you can tune spot-on just by turning the knob very slowly. Newer radios approach the problem a different way. Newer radios either have a PLL or DDS VFO which tunes in discrete steps. The problem is, you want to go quickly when QSY-ing to the other end of the band and then you want to go slowly when you tune to the final frequency. I have seen two approaches to this problem which work pretty well: 1. use a small step-size but have a free-wheeling weighted VFO knob that can be spun very quickly to make gross frequency changes and yet still have a reasonable step size, usually around 10Hz, that will let you tune in the desired signal when you get near; 2. use acceleration to increase the step size when tuning quickly, e.g. 100Hz, and then change to a smaller step size when tuning slowly. The problem with the Griffin knob is that you can't spin it. So in order to move quickly you need to change to a much larger step size. That precludes final tuning of the signal without changing the step size again. Some use the ability to push down on the knob to change the step size but then it is more awkward as you are trying to push and turn at the same time. So the only way to make the Griffin knob work well would be to apply acceleration when turning the knob rapidly. So you can see why the Griffin knob is not particularly useful AS IT IS CURRENTLY IMPLEMENTED. If one were to add acceleration to frequency selection in PowerSDR, the Griffin knob would become very useful and desirable. As it is, I think most people have adopted the same approach to solving the problem: drag the panadaptor display for gross frequency changes and use the mouse-wheel for fine tuning. Both are accomplished from the mouse which saves moving one's hands around to different places. If that is going to be the preferred method of tuning the radio then I would deprecate the use of the Griffin knob entirely. Here's a question: does anyone use the keyboard shortcuts to tune the radio? I know there are keys that will tune up/down for the various digits in the frequency display but in over a year of use I have never been even slightly motivated to use them. Am I the rule or the exception? 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
Re: [Flexradio] Shure 444 mic
Hi Leon, I don't have the 5000, but I do have an HPSDR system (Penelope) and I use my old Shure 444 with great results. The input characteristics of Penny are probably similar to the 5000. What Tim says about the characteristics of the mic is true, except that the frequency response peak is at about 1200 Hz, not 3k. You do need to buffer the output to match the impedance, as Tim suggests, BUT don't try and flatten the response using any EQ. The Shure designers made the response of their mic like that for an excellent reason - it provides far more effective communications in rough conditions. I use mine with an outboard RF clipper, which has even more pre-emphasis in its input circuit. 73, Greg, ZL3IX Tim Ellison wrote: I don't have one, but based on the wiring diagram, Black=mic(+) White=PTT Shield=(PTT and mic ground) The Shure 444 has a very narrow frequency response range (300-3000 Hz) with a gigantic pre-emphasis at 3000 Hz. The FLEX-5000 has a flat frequency response so you are going to probably have to use aggressive EQing to cut the 3000 Hz range to get it to sound acceptable. It is also a very high impedance mic, @ 10K ohms. The FLEX-5000 is not designed for high impedance and unbalanced loads and you may have to use a direct box (DI) to lower the impedance and convert the signal from an unbalanced to balanced load. IMHO, this mic is not well suited for the FLEX-5000, but that doesn't mean it can't be made to work.

[Flexradio] PowerSDR and RTTY
In the past couple of months there have been several DXpeditions that seem to have put quite an emphasis on RTTY, even to the point that the chances of working them at all are considerably reduced if one does not use that mode. I have therefore decided to try it out, as it would seem to improve my chances of a QSO with these guys. I would appreciate comments from folks using PowerSDR for RTTY. What is your setup? Are you using MMTTY? Which mode do you select, and which filter? Do you use a wired audio connection back into the PC sound card, or VAC? Any other comments would be appreciated. I have tried MMTTY with a wired connection myself, but I was not too impressed with the results. I certainly think I would have managed a CW contact at S/N ratios way below where the RTTY decoder gave up and printed garbage.

Re: [Flexradio] SSB Tx Audio Punch
What I am about to write may not be very popular, and I am likely to be shot down in flames. Please believe me that I mean no offence, and would just like to share an opinion that has been developed over many years of HF SSB operation, both on the amateur bands and on military HF comms circuits. While the new SDR world brings many huge advantages to the radio experimenter, we must be very careful not to throw the baby out with the bath water when we discard analogue techniques. IMO, the speech processing area represents the very crown jewels of an HF radio transmitter, as it is critical to the overall operation of the radio. I therefore believe that developers should be very careful when they tinker in this area, and such work should not be undertaken lightly. Before presenting new code for evaluation, the following bench testing should be done. (On the air testing is VERY time consuming, and requires contacts under the right propagation conditions which are not always available) Test 1. Adjust the OUTPUT level on the UUT (unit under test) to give the required peak output power while whistling into the mic Use an average reading power meter. Then say aargh into the mic, and adjust the INPUT level for half of this power. Eg, 100W indicated for a whistle, and 50W for aargh. Then go back to the whistle if necessary, and re-adjust the OUTPUT for 100W. Iterate as necessary to achieve both these results. For an RF clipper, this represents approximately 15 dB of clipping. If this 2:1 power ratio cannot be achieved, then the UUT fails the first test. Note the input level for the whistle using a scope. Test 2. Using an audio signal generator at a frequency of 700 Hz, feed in the same level into the UUT as the mic was giving for a whistle. Do NOT adjust the input or output levels of the UUT. Check the output of the radio on a spectrum analyser, and ensure that the products at 1400 Hz and 2100 Hz offset are at least 30 dB down. This can also be done at some intermediate test point if available. If both the above tests pass, then it is worth while to try some on air testing. The other parameter that affects on air intelligibility is audio frequency response. The mic itself should peak at about 1 kHz (eg Shure 444), and there should be ADDITIONAL electronic pre-emphasis with a time constant of about 160 us. This gives a roll-off below 1 kHz of 6 dB per octave. Many operators (especially the AM HiFi bunch) will hate what I have said, but under difficult weak signal conditions, a radio performing as above will give the most intelligible signal. From a performance point of view, it really doesn't matter whether this is achieved by analogue processing external to the radio, or internally in DSP. The result will be the same if the correct principles are followed. In my experience, it is very difficult to achieve these results with processing performed at baseband. Envelope tracking comes the closest. In principle they are easier to achieve with IF/RF processing. 73, Greg, ZL3IX Ian Scoble wrote: Please can anyone else confirm whether they are having audio punch problems on SSB, the problem seems to have occurred since the SVN upgrade on or around 1840.

[Flexradio] PowerSDR with Logger32 and VCOM
I have a set up a VCOM CAT link between Logger32 and PowerSDR. The link works, except that, if Logger32 is booted up before PowerSDR, either manually or under automatic startup, it sends a CAT request to the radio for frequency before it can reply. Seeing no reply, Logger assumes that no radio is connected, or will be connected, and doesn't try again. (In contrast N1MM warns the user, and tries again. N1MM doesn't have some of the other features of Logger though) I could decide to start Logger manually after PowerSDR is up and running, but that really should not be necessary. Has anyone found a way around this in the Logger32 setup? I'm sure there must be something I've missed. 73, Greg, ZL3IX ___ 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 Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/

Re: [Flexradio] audio punch
My experience of listening to the SDR1000 on the air is also that there is no audio punch. I keep a sked with a ZS every Friday over quite a difficult polar path. He has two radios, one an old analogue rig with an RF clipper, and the other an SDR1000. When the path is especially difficult, or there is some auroral flutter, the SDR is almost unusable. I have raised this issue with the SDR software guys, asking if/when there is going to be an RF clipper included as an option. Reactions have been mixed. One guy said he appreciated that RF clipping was the way to go, but the other is not convinced. I am intending to replace my ageing analogue rig with an HPSDR, but will not put in on the air on SSB until the Tx audio issue is resolved. I was hoping that somebody else would write the clipper software, but it doesn't look like that will happen in the short term. I will therefore have to have a go myself. The problem is that, although I have written some C in the past, software development has left me behind a tad, and it will take a while to catch up. I have, however ordered Visual Studio, and when it arrives I will start my re-learning process. I DO intend to have an RF clipper in my HPSDR, even if it takes a while.
