Scott,
About OM6BPF, for info, I would give a 10/10 and would buy the same if I had to
redo it.
Doing contest in SO2R (low power), I never noticed any interference between
radios (even with the 40m beam 3m above my OB11-5 beam on the same tower)
except of course on harmonic frequencies.
That said, I don't understand how you can remove interferences between radios
if you don't have band pass filters after the amplifiers...

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
