You might look at the NB3N502 PLL mult chip. I've used this chip on my rubidium interface board and other projects. It's cheap, current production and does a number of multipliers from 2X 2.5X 3X 3.333333x 4X and 5X Available from Mouser and others. I'm using one in a hybrid CW transmitter as a nearly coil-less scheme with a 6CL6 final. all 5 bands from either a 80 meter or 40 meter crystal. Keys really clean too. Bob, KE6F
