[TowerTalk] ICE 419-B info.

[Jim Brown]

The ICE 419-series BPF sets are the bottom of the barrel. They don't 
handle power or SWR, so they're very easy to blow, which requires 
difficult disassembly and realignment. And when you do all that, you 
still have a lousy filter set. And if that isn't enough, the relays also 
go intermittent, also require that disassembly.

My measurements of BPF filter sets used within NCCC were published in 
NCJ about four years ago. The review is on my website.

The report is based on measured data using a VNWA3e Vector Network 
Analyzer, and plots of the data for each filter can be accessed for each 
unit on each band from this webpage.

My advice is that if you have a problem with the ICE filter set, bite 
the bullet and replace it. The two I owned are long gone.
