Re: [Flexradio] XG-1 as an accurate frequency source
Title: XG-1 as an accurate frequency source Got it. Obrigado Eric. -Tim --- Integrated Technical Services "You can't close the door when the walls cave in" --Robert Hunter From: Eric Wachsmann - FlexRadio [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 08, 2005 3:04 PMTo: Tim Ellison; 'Flex Radio'Subject: RE: [Flexradio] XG-1 as an accurate frequency source Tim, Sure. The XG-1 should work fine. A stronger signal would likely give you a better chance of getting a better null (you will run into the noise floor much sooner with the XG-1). You can use another transceiver if signal level is an issue though. The actual signal level and signal frequency used for the image null isn’t really important (unlike the Frequency and Level calibrations). The main thing is that you are able to null the image of the signal.

I have read the section about DDS clock adjustment and Image Null calibration procedures and I do not have a frequency generator. Rather than trying to use WWV can I use my XG-1 and set the frequency to 7.040 MHz for testing purposes? Is it accurate enough for these calibration tests? 73 de PY0/W4TME -Tim --- Tim Ellison Integrated Technical Services Apex, NC USA 919.674.0044 Ext. 25 / 919.674.0045 (FAX) 919.215.6375 - cell Skype: kg4rzy smime.p7s Description: S/MIME cryptographic signature
