I have been doing a lot of review and familiarization of this project for the past month (looking up parts and examining the eagle files) before I start building. Looking at these forums I've seen a number of people who have said they used different VCO's from the Ladyada Wavebubble project (e.g.: viewtopic.php?f=16&t=30621). I am wondering why the choice in different VCOs?
Is it simply for the increased spectral coverage? And if this is the case, why bother? As I understand it, the Ladyada project VCO's should cover all the cell phone frequencies anyways...
Any enlightenment is much appreciated. Thanks!
