This afternoon I have "tested" two circuitini PLL achieved around a integratino Silicon Lab 's Si570 that interface with a PC via the USB port, you can swing up to about 270 MHz with a resolution of a Herz!
All this was made possible through a small kit found online at: http://www.sdr-kits.net/ , which uses compact enough (even) and SMD technology that at first worried us (me and to Caesar, XCK) a little, you know old age ... could invent these components when we were 20 years!
This worked the first time (or almost) as usual the only problems occur there (to us old ardueristi) with the PC and its software! In the end we managed to "turn" the whole, now you just have to try it combined with the receiver SDR Caesar.
