What's your reference frequency? I mean, prescaler ratio and pll step.

Reference frequency is given by a 5.12 MHz crystal, divided by 1024,
that makes 5 KHz steps. The prescaler divides by 64/65.

I see others in sed have given valuable advice.

Seems like shielding will improve things. One other thing, try to power
the radio and the PLL from different sources just for a test. You'll need
good power decoupling to eliminate spikes generated by the PLL circuitry.
