Tom, There is one benefit for me when using Spectrogram 16 - it has a larger display area, and therefore greater resolution and interpolation is available. BUT, it has more setup parameters and a few more bells and whistles that are of no use to me.
Version 5.17 is entirely suitable for aligning the K1/K2 filters and does match your documentation for setup and operation. Other versions have different setup data. So my recommendation -- if you are a "newby" to using an FFT based audio spectrum analyzer, download version 5.17 from Tom's website and follow his documentation for setting it up. If you are interested in further enhancements after you have become familiar with the operation, then download version 16 (the last freeware version) and do whatever you wish with it - it has a lot of capability. 73, Don w3FPR On 12/29/2010 4:10 PM, Tom Hammond wrote: > John: > > There are several(!) versions of Spectrogram available. > > IF you are planning on using Spectrogram to align your K2 or K1, then > I'd suggest getting Spectrogram v5.1.7 from my web site... it's > located immediately adjacent to the printed documentation for > aligning your radio (K2 or K1), depending upon which rig-specific > page you've gone to. > > You CAN use newer versions of Spectrogram with my alignment docs, but > there's absolutely NO benefit in doing so and newer versions offer > features you will not need nor wish to use. > > Visit: > > For the K2 - http://www.n0ss.net/index_k2.html > > Spectrogram and docs are located about 3/4 of the way down the page > > For the K1 - http://www.n0ss.net/index_k1.html > > Spectrogram and docs are located about 2/3 of the way down the page > > The ONLY additional device you'll need is an audio jumper cable from > the radio;s > speaker output to the input of the sound card on your PC.
