 		 #186100 - Too Bad...
Responding to: Kai Klaas's previous message
Too bad the input frequency range is so low. If it was in the 1-5 MHz range there are nifty little 8-pin ICs that can up convert by pin selectable ratios. Sometimes two of these can be used in series to attain other net up convert ratios.
