Modified a LCDFSL-1201MS with an internal Picaxe chip to program the PLL.
A pin on the external connector allows me to select one of two programmed frequencies.
It also programs the AD5200 (smaller IC to the right of the PLL) to match what the Elcom micro did.
Mine is programmed to produce either 11,736.00MHz or 11,735.75MHz.
These go to a x4 to give LO frequencies for 144MHz or 145MHz I.F. on 47GHz.
