Hi Scott,

Here I use the OM6BPF by OM-Power Cie. Very good results here (except on harmonic frequencies like all BPF, e.g. R1 on 7.150 and R2 on 14.300)

Objet : [CQ-Contest] Thoughts on automatic low-power bandpass filters 

I use ICE 419B band pass filters between my transceivers and amplifiers. 
  They work, but I realize that others may work better.  To my knowledge, 
these are the players in the low power (200 watt) automatic band pass 

New prices listed
$318 ICE 419B
$505 Dunestar Multi Band Remote Switched Bandpass Filter
$700 DX Engineering 419 Automatic Band Pass Filter Systems
$700 AS-419 - "BandPasser II"

Are there other systems out there?

What is your experience with each of these?

How would you rank them?

Has anyone modified and published a "how-to" to modify the ICE system 
for better performance?
