[hpsdr] JANUS BoM

[Christopher T. Day]

Thanks, Lyle. Yes I meant 0.22 uf. And I guess I'll just go through
Digikey for the 2700 pf COG capacitors unless we expect a _LOT_ of
orders for Janus.

Hello Chris!

This is part of the sigma-delta roll input filter, probably doesn't have

to be C0G. Since it is in the critical signal path and could have some 
impact on phase drift with temperature I elected to use a C0G part.

I think you meant 0.22 uF, and I bought Mouser 77-VJ0805Y224KXJTBC for 
my alpha build.
