Ken, If you want an even more challenging and exotic use of Spectrogram, consider using a diode ring mixer and a signal generator to convert an RF signal down to baseband (audio), amplify it a bit with an op amp and you can feed the output to the soundcard to be used (with Spectrogram) as a narrow band spectrum analyzer.
This is a realistic way to examine the close-in frequency spectrum, such as that of an SSB transmitter output. Feed the K2 with an Elecraft 2T-gen to examine the spectrum of the transmitter. The concept comes from The Measurements chapter of Experimental Methods in RF Design, so I calim no originality for the design - only the application with the 2T-gen. No, I have not yet written this up for my website. 73, Don W3FPR > -----Original Message----- > From: Ken Kopp [mailto:[EMAIL PROTECTED] > Sent: Thursday, March 01, 2007 8:58 PM > To: [EMAIL PROTECTED]; Ron D'Eau Claire; 'Elecraft Discussion List' > Subject: Re: [Elecraft] Frequency counters for Alignment > > > Great suggestion, Don!
