[INRAD] filter comparison

[Anders Janis SM4RNA]

The Inrad crystal filters is better than Collins.

The "bad" selectivity on the IC-718 is du to that Icom uses a simple Murata 
filter for SSB. If I had a IC-718 I would buy a 400Hz Inrad filter and 
install in the empty place. Then I would remove the Murata SSB filter and 
Wire in a 2,4kHz Inrad filter.
