    Review  –:

    You get what you pay for, and this is an excellent addition to any shack. The Compact-In-Line is pocket sized and being able to use AA batteries, as well as an external DC source (Lead supplied) makes it useful for portable operating. I have found it capable of resolving speech otherwise totally lost in noise. It is simple to use and does exactly what the maker claim. Even if your radio has built in noise reduction, the performance of the Compact-In-Line will surprise you.
