No reason the PLL frequency should change between TX and RX

Just goes to show that YOU really don't understand the technology
that your dealing with...... Maybe a few courses in Modern
Radio Design, would help you understand how the PLL System
works in an FT480R.....


Which bits of it do you say that I don't understand?

Loop stability in control systems, perhaps? Lead/Lag
compensation? Triple loop PLLs to give 10Hz steps but
without the final loop stepping in 10Hz?

What exactly?
