Re: [Flexradio] Problem with adapter USB
One other possibility that I've experienced with a Shuttle PC is that the USB ports on the machine are unable to supply enough current to all attached devices (I have a Netgear wireless USB dongle that is really power hungry) and that can cause all sorts of weird problems.

If you had already plugged it in before, you may have to go to the Device Manager to update the driver for #3. 3. When prompted, select the C:\Program Files\FlexRadio Systems\USBIO directory and the driver should install. 4. Start PowerSDR and check the USB Adapter checkbox on the Setup Form -> General Tab.

[Flexradio] UK 60m spot frequencies
Not sure if this has been asked before, but if it has I can't find the answer. I have an application in for a variation to my licence to allow me to transmit on 60m. Thing is, the UK spot frequencies differ from those in the Power SDR console. I have had a go at adding them to the Band stack table and band text tables in the database and they do appear in PowerSDR with the correct frequency and tag as the 60m button is repeatedly pressed. However, despite marking transmit as true in the band text table I get a "not in IARU bandplan error" when I try to tx (into a dummy load I hasten to add).

Re: [Flexradio] 16 versus 24 bit audio
Sorry Peter - should have said - these figures are with SDR hardware turned off and unplugged/inputs shorted out. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Peter Martinez Sent: 20 May 2006 11:51 To: Flex Reflector Subject: Re: [Flexradio] 16 versus 24 bit audio >From G3PLX: Thanks Paul. Thank goodness I am not alone! I just did a simple calculation. The ultimate rock-bottom noise power is kTB, where k is Boltzmann's constant (1.38e-23), T is room temperature (300 degrees K) and B is the bandwidth in which you measure it - let's say 24kHz for a 48kHz soundcard, so this works out to 1e-16 watts. Let's say the circuit is 600 ohms (just so we can get some idea of the picture), so the r.m.s. noise level across a 600 ohm source connected to a soundcard is going to be the square root of 600e-16, or 0.244uV. Again, just for the sake of it, let's say the soundcard ADC is designed for 2.2 volts peak-to-peak (that's 0dBm in 600 ohms). A 24-bit ADC would then give 2.2/(2^32) volts quantisation level. That comes out to 0.13uV. That's not far off the circuit noise level. That 'feels' about right to me. It says that an 'ideal' 24-bit soundcard should just be able to 'hear' it's own input noise. This is how we have always designed the front-ends of things! I am just throwing numbers in there, and the experts may say that the circuit isn't 600 ohm, or I haven't taken into account the noise factor of the pre-amp, or the typical ADC full-scale isn't 2.2 volts. But I am surely not wrong by a factor of 256? Where is all the noise coming from? Paul's observation that the noise is 100dB down on full-scale could just mean that there is that much noise coming from the SDR1000 RF hardware, but it would be easy to test this by unplugging it and short-circuiting the soundcard input. If the noise stays at the -100dB mark then it says the soundcard is that noisy, which is exactly what I find here with the Firebox. Maybe Paul has already done this. Note that the software measuring the noise needs to be set to the full soundcard bandwidth for this to make sense - it will look a lot cleaner if you select a narrow filter. I am not familiar with the SDR software so I don't know how this works. 73 Peter ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
Re: [Flexradio] 16 versus 24 bit audio
Peter, I asked the same question in a different way a while back. I noticed that with no inputs to the Firebox (or Delta 44 - I have both) the analogue input meters on the SDR software were reading in the order of 100dB down on maximum. Doing some simple maths the theoretical minimum fro a 24bit sample is 145dB down so where is the other 45dB of noise coming from? I may be over simplifying things but something doesn't seem right? As for dithering I read an article recently (maybe from Analog devices - can't remember) and do remember them talking about 1bit dithering. What I was trying to ascertain is whether there is a hardware issue or if it's a software issue (conscious design decision or otherwise). Apologies that this hasn't helped answer anything, but at least one other on the group is asking the same question!

If I understand the idea, they introduce some deliberate noise in the ANALOGUE part of the ADC in order to spread the spectrum of any quantisation noise. Without it, I can imagine a tiny sinewave input of, say, one bit amplitude, looking to the software like a one-bit squarewave, with 3rd, 5th, ... harmonics. Dithering the analogue input would add a little noise to the fundamental sinewave but push the harmonics down. But, as you say, surely they would only introduce about one bit's worth of dither noise, not eight? 6dB not 48dB? I just did some proper measurements on the Firebox. On runs of 1200 samples at 48kHz, the r.m.s. noise level on the line input is about 400. It's about 450 on the Mike input. I did this by squaring each sample, summing these, dividing by 1200, and taking the square root. At the same time I calculated the DC level, just to make sure that was a lot smaller and didn't confuse things. This is about 9 bits of noise, or more if you suppose the peaks are higher. On the built-in 16-bit card in this laptop the DC level is 15 and I am not sure how to allow for this in the r.m.s calculation, but only the lsb toggles randomly. The MP3+ is the same, unless I select the mike input when the rms noise level is about 10. These figures are what I would have expected intuitively. One would expect the analogue noise-level to be roughly the same as the quantisation noise, in the same way that one would optimise any receiver so that all sources of noise contribute more-or-less the same in order to maximise the dynamic range. Intuitively I would have expected a 24-bit card to do the same, but maybe I am being naive. These measurements, and the figure quoted by Alberto, tells me that the "24-bit" figure in the spec. is to some extent a marketting ploy. I can imagine a scenario where the designer of a new soundcard measured that it only gave 18 bits of useful data, so he decides to mask the data to 18-bits and sell it as an 18-bit card. The marketting manager of the company would surely override him, especially if the competition were all actively marketting so-called 24bit cards! 73 Peter ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com

[Flexradio] External Linear Keying
Hi all, I've a question about the connections for keying my linear. I understand the concept of open collector, it's limitations (current, voltage breakdown etc.) and have used this approach to switch my linear before. However, the protection diode thing is confusing me. Usually I would connect a diode across the relay coil to prevent back emf problems when de-energisjng the relay coil. So what does the "connect the protection diode to the relay positive supply" comment mean? I don't want to hack my linear open to get to the relay +ve supply. It may be me but don't think the manual is clear on how to establish the interface. Am I better off using an external opto isolator or do I just connect everything up assuming the relay in the linear doesn't draw too much current (switches OK with my K2) Cheers, Paul M1PAF
[Flexradio] New owner - what noise floor should I expect
I have exactly the same figures so I guess everything is OK. Still don't understand the noise levels with the radio powered off though? -Original Message- on 80M with my antenna terminated in a 50 ohm dummy load using the firebox with 100hz BW and the preamp on high my noise floor is -138 to -140 dbm at its lowest. If I put on the antenna (full size 80M 1/4 wave vertical) my noise floor is about -115 dbm.
[Flexradio] New owner - what noise floor should I expect
Hi all, Had my SDR-1000 for three weeks now and am now getting to grips with it. Have a few questions though (receiver calibration done using XG2): The background noise level on the analog inputs (SDR switched off) is around -86dBfs using a Firebox. Is this normal as it seems high to me (+/- 1 bit at 16 bit resolution gives a theoretical -96dBfs so there is 10dB of noise)? Also the card is capable of 24bit so noise floor should be lower My 80m noise floor in the evening is around -110dBm which equates to around S5. My K2 shows nothing like this level and "sounds" quieter (although K2 S meter is only accurate at S9) - does this seem reasonable? Also have noted that the Firebox is quieter with the external PSU connected by about 5dB Cheers, Paul M1PAF
