Re: [Flexradio] Frequency Calibration on Recent SVN's
I've noticed that the software does not cal wwv properly for some time now, On my radio it is always been down the band some. There is an absolute no fail method of calibrating wwv that I've found through the help of some of my buds. I use double sideband to manually calibrate and it's a completely fool proof, dead nuts on the money everytime tuneup. On my rig I can barely even understand wwv until it's very close to being on the money. That's the methid I use. - Original Message - From: John Hansen [EMAIL PROTECTED] To: flexradio@flex-radio.biz Sent: Sunday, September 10, 2006 10:51 AM Subject: [Flexradio] Frequency Calibration on Recent SVN's I noticed that the frequency calibration was off on a couple of the recent SVN's (WWV at 10 MHz was about 20 Hertz low).

Re: [Flexradio] Frequency Calibration on Recent SVN's
Just to add to Jimmy's comments. After allowing the SDR-1k to warm up for hours, I tried the DSB method described here where you zero beat the constant tone with ticks (not just the ticks alone). After calibrating from wwv using 15.0 MHz, the DSB method indicated that the zero beat frequency was 14.95. This is easily done visually too by using the scope. When you are not on frequency, there are two separate waveforms on the scope. As you get closer to the zero beating the tone, it will appear as one waveform in the middle of the screen that doesn't jump around. Now the real question: is this a problem with the calibration routine of just an anomaly of using a frequency standard that is effected by atmospheric and solar factors? -Tim --- Integrated Technical Services Too much of everything is just enough. -Bob Barlow -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jimmy Jones Sent: Sunday, September 10, 2006 12:15 PM To: flexradio@flex-radio.biz Subject: Re: [Flexradio] Frequency Calibration on Recent SVN's I've noticed that the software does not cal wwv properly for some time now, On my radio it is always been down the band some.

Re: [Flexradio] Frequency Calibration on Recent SVN's
Exactly Another weird little thing I've noticed when tuning using DSB is in the phase display mode. According to which side of center your on the display will move in a clockwise or counter-clockwise direction. I think ideally it should be completely stopped and inthe middle of the display but my rig will not even come close to that. I love this little sdr though. - Original Message - From: Radio Station W5AMI [EMAIL PROTECTED] To: Tim Ellison [EMAIL PROTECTED] Cc: Jimmy Jones [EMAIL PROTECTED]; flexradio@flex-radio.biz Sent: Sunday, September 10, 2006 12:36 PM Subject: Re: Frequency Calibration on Recent SVN's On 9/10/06, Tim Ellison [EMAIL PROTECTED] wrote: Now the real question: is this a problem with the calibration routine of just an anomaly of using a frequency standard that is effected by atmospheric and solar factors? I have had problems before when the signal was not sufficient. I suspect a lot of QSB or in particular a lot of fluttering on the signal would drastically effect the ability for the calibration routine to work properly as well. I wonder if setting the rcve filter to a very narrow pass-band prior to running the calibration would help, hurt, or not matter at all. Without looking at the code, I haven't a clue. Eric; what actually happens there? What mode, filters, etc., are used during calibration? Are those parameters hard coded, or does it use the mode and filters the user has set? Brian / w5ami PS: I am still able to calibrate just fine with the current svn. -- No virus found in this incoming message. Checked by AVG Free Edition.

Re: [Flexradio] Frequency Calibration on Recent SVN's
John, I have noticed/experienced the same thing. It has nothing to do with weak or fluttering signals. The 10 MHz WWV signal was very strong and steady and I get the error message, but not at 5 MHz or 15 MHz. Only on 10 MHz. 73 Joel W5ZN -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Hansen Sent: Sunday, September 10, 2006 1:42 PM Cc: flexradio@flex-radio.biz Subject: Re: [Flexradio] Frequency Calibration on Recent SVN's FWIW, I found that if I used the WWV signal at 15 MHz the calibration procedure appeared to work. If I try it at 10 MHz, I get the error referenced in my previous message. The 10 MHz value appears to be broken in the current SVN version. Thanks, everyone, for the suggestions.

Re: [Flexradio] Frequency Calibration on Recent SVN's
I use the Phase 1 display and SAM mode. Use the Freq Cal button to get close. On the Hardware Config tab you can use the up and down on the DDS Clock Offset to jump by tens until you get the pattern to rotate slowly clockwise and counter-clockwise. Then you can type in values in between to get it to stop. WWV is not drifting. At least not an amount that you would be able to measure. If you have the thermistor crystal heater stability mod, and your SDR-1000 has been on a while, you can get quite close. The instability left is probably from changes in propagation path, ignoring possible CPU clock and sound card clock drift. If you watch it for a while, you can get a feel for the propagation changes and have a pretty good inference for the actual frequency. When I got my SDR-1000, I wondered why anyone would ever need the phase display. Now I would miss it if it were gone.
