Topband: Ferrite Cores

[Tom W8JI]

In this discussion two different ferrite mixes are mentioned: #31 and #61.

would be more suitable for lower frequency applications. >>>>

Core selection can be fairly complex in transmitting systems. I've yet to 
see a case where one core mix is the be all end all for the range of things 
you run into in the field. Especially at high common mode impedances.

Receiving is a completely different story, because core stresses are always 
low.
