Re: [Flexradio] Spurs and Picket Fences
The only spurs I find in the passband on my SDR-1000 are "travelling" spurs that slowwwly migrate up and down in frequency and through the passband. These create a rising or falling get, and are very annoying when they occur. Some are as strong as -90 dB. I understand they are related to a DC-DC converter. I'll probably send my SDR-1000 back to Flex some time for a checkout, if I can bear to part with this otherwise great rig!

Re: [Flexradio] Spurs and Picket Fences
I guess the key word here is "see". Only in the SDR can you see the spurs, even if you can't hear them..Most of the spurs I see, are gone by the time they arrive in my passband. Any radio will have some spurs, but they only worry about the ones that can be heard. I'm sure that the SW can be taylored to eliminate all the spurs, but I am not sure that you could afford to run the computer that would be fast or big enough to run it.. 73, Dudley WA5QPZ >On Mon, 14 Aug 2006 12:20:59 -0400, Richard Smith <[EMAIL PROTECTED]> >wrote: > > > I'm new to the SDR-1000 and have a question about spurs.

Re: [Flexradio] OT : USB <-> Parallel
Jim, thanks for your answer. What I would like to do is to manipulate the pins of a DDS on an external board, which are connected to the pins of the parallel port. The protocol is with two wires (clock and data), serial. You have to send out 40 bits to change the value of the Frequency Tuning Word to set a new frequency. With a real parallel port it works beautifully, I am able to scan frequencies even at 20 new values per second (I don't need more, so stopped here, but maybe it is possible to go higher). My concern is that I would like that this program could run also on laptops without a real parallel port, making use of a USB<->Parallel converter. I use a third-party kernel driver that allows me to do physical I/O even from Windows XP, and was convinced that those converters came with a device driver that fully emulated the parallel port, up to the point of being able to do direct I/O to the pins. Apparently I was wrong, unless some brands and/or models of those converters behave like that. If someone has suggestions, please don't be shy... :-) 73 Alberto I2PHD Jim Lux wrote: > At 10:03 AM 8/10/2006, Alberto I2PHD wrote: >> Please excuse me for this OT request, but I think that in this group there >> are a few who have played with the USB to >> Parallel converters, generally in form of a cable (with some chips in the >> connector shell). >> >> Are they good for a printer exclusively, or can I drive the single pins of >> the parallel port, not only the 8 data bits, >> but e.g. the Strobe pin, the AutoFeed pin, the Initialize pin, etc. and in >> the reverse direction, can I read the Busy >> pin, the PaperEnd pin, the Select pin, etc. ? > > > Not usually.. they don't show up as a i/o device...

Re: [Flexradio] dx4win
George, I went back into my two year old data where I originally tested the CAT software and found that I had tested the logging function of DX4Win but not the digital modes. Since it did work fine as a logger, I wouldn't think it would be difficult to get the digital modes running. Check out the links on the FlexRadio website "Expert Setups | CAT/Digital" menu and let me know if you need any additional info. 73, Bob, K5KDN -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of george frost Sent: Sunday, August 13, 2006 9:54 AM To: flexradio@flex-radio.biz Subject: [Flexradio] dx4win Has anyone tried to use the dx4win PSK and RTTY with the flexradio?

[Flexradio] VAC + MultiPSK
I've not had any success with VAC (3.12) and Multipsk. Anyone able to connect Multipsk with VAC? Multipsk error reports that VAC is "already in use" by another program on my setup. I have no other program-in-use but PowerSDR. Tnx Mel, K0PFX -- next part -- An HTML attachment was scrubbed...

Re: [Flexradio] VAC + MultiPSK
I think I've seen this message before when the PowerSDR VAC settings don't match that of the third party software. Double check whether it is stereo/mono and what sample rate it uses.

Re: [Flexradio] Spurs and Picket Fences
I have the same issues, 10M, and 6M are full of spurs, even 20 meters has a few in there. I believe that on the lower bands they are there also in fewer number, but you just don't see them because of the noise level being so high.

[Flexradio] Spurs and Picket Fences
I'm new to the SDR-1000 and have a question about spurs. I've read the reflector, and understand that right now, spur reduction has more to do with moving the spurs out of the filter passband as opposed to eliminating them. However, on the quiet upper bands with very low noise floor, I see serious spurs on the panadapter as I tune across the band. I can often hit frequencies where the entire spectrum lights up like a picket fence and includes spurs within the filter passband as well as across the rest of the 48 kHz of spectrum. On the lower frequency, noisier bands, I notice similar behavior with no antenna, but don't notice the spurs in normal operation once the antenna is connected and the noise floor comes up. Is this normal, or do I have a problem with my SDR-1000? Short of the brute-force algorithm that has been discussed for taming the DDS, is there anyway to fix this abnormal looking behavior? Thanks.

Re: [Flexradio] dx4win
I have not used DX4WIN, but I would imagine you could use the VAC Setup and Use document or even the Operating Manual (both available on our download page at www.flex-radio.com) as a general outline of what you need to setup to make it work properly.

Re: [Flexradio] VAC
If you already have v3.12, the later versions won't buy you much at the moment. Eventually we expect to have WDM-KS driver support which will allow lower latency digital operation.
