Two Questions about the Mini SA


 


Hi there,
?? I would very much like to build and experiment with this exciting project and I have established that I can get all the bits needed to do it - except one.
??? I have not found a filter module seeller that gives the? bandwidth. Indeed most advertisers don't mention bamdwidth at all. Obviously Erik made his own so I decided to do the same. But I have looked at every list of EPCOS SAW filters that I can find, and none of those include bandwidth either!
??? So I am hoping that somebody can come up with a part number of a 1MHz bandwith version.

?? Secondly, the pictured Si4432 modules are on blue PCBs. I can only find black ones. Does it matter?

???? Of course I must finish by thanking Erik (If he reads this) for sharing this with us.
