Jeff, regarding stubs on six-pack, I place mine on the six individual
band ports. A few are "Tee-d" in right at the SO239 on the six pack, but
most are connected with a "T" a short distance away.
I need to rethink this, based on the knowledge that there is a proper
distance that the stubs should be placed away from the amplifier output,
and that the distance also depends on the tank circuit of the amp. My
amps are different, and I couldn't tell you how long the coax lines are
between the amps and the six pack without measuring them.
I can say that my stubs do make a difference.
Frank W3LPL can you steer me towards any references discussing how to
eliminate RFI from T2X controller boxes? I have three of them.
