Both of these oscillator I built for any channelized radio purpose . PLL, the upper row, using common design TC9122 but the display I take from IK3OIL using 7 segment because it is looked brightly for an old man like me especially in the darkness of the night. Another advantage of this display is programmable offset so it can be used for any frequency of IF.
The second row is FLL, it is also from IK3OIL, but there is somewhere modification in oscillator region. Now I used it for FT 300 C oscillator for base station and PLL + FT180A I install in the car.
