Re: Assistance with modulator design
Hi everyone,
I just wanted to let you know that I am in the process of designing a modulator with PLL that can be tuned accurately to any frequency in 250kc increments. It will use an old Motorola MC145106 PLL chip that can be set up with a simple dip switch -no processor or programming required.
After reading Matts post I am now thinking of making a combination of this PLL and the TDA 5660. This would give any audio-vision spacing with FM carrier and can be tuned to any frequency in the VHF bands.
