[MAMS] PLL

[Zack Widup]

Hi Wally,

What do you plan on using it for? You have a 5760 transverter, don't
you? I think I worked you on that band. (BTW we need to try for 3456
again some time! Maybe this weekend?)

For a 144 MHz IF, you'd want a 5616.0 MHz LO for low-side injection.
For high side injection you'd probably want to use 5905.0 MHz and tune
down from 145 MHz. My personal preference is low-side injection
because I don't like tuning backwards. Looks like that MIGHT be a
little low for its range with low-side injection. If the price is
right I'd probably get one to experiment with but I don't think I
personally would spend over $25 on one.

Come to think of it, I may have a Frequency West brick for that range
that I never used. I think I got it for $10 on eBay a few years ago. I
was thinking of making it into a beacon at the time.

73, Zack W9SZ
