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
arena:
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?
--Scott, W5WZ
