Multi-band beacon #18

Closed timhavens closed 8 years ago

timhavens commented 8 years ago

I have an issue I'm trying to understand and resolve. I've been working on a mulit-band beacon where for 50 MHz I use CLK1 @ 50 MHz, and 144 MHz I use CLK1 @ 144 MHz.

For 222 and 432 I use CLK0 as an LO to a mixer, and CLK2 as the IF to the mixer and the output = 222 or 432 MHz.

This works.

However, after I use the Si5351a for 222 and 432 MHz and the loop goes to do 50 MHz on CLK1 again it no longer outputs.

I keep thinking this may be an issue where something isn't being reset like the PLL's.

I've tried to set PLL's for each band, but I'm not 100% sure I'm doing it right.

I can set PLL for a single band ok and it seems to work.

I'm stumped. I can provide my sketch if that would be useful. I suspect it's something simple I've missed. But after a week of trying and researching I just can't seem to resolve the issue.

Can you help set me straight?

Never Mind, I found my error. It's working
