[TenTec] Ten-Tec 411 Centaur Amp Problem

[Mike Schatzberg]

Yes, the article mentions the use of the line isolator which is indeed nothing more than a hunk of ferrite slid over a piece of coax. 73, Mike W2AJI

This was a great article and interesting approach to solving that problem.

One thing I have almost always done is to use an RF-Choke between my
transceiver and amplifier.
Any time I had any kind of funny thing going on, on one or more bands, it
usually cleared up with one of these chokes.
It might just work and it is a lot less work than pruning a length of coax.

My chokes are the ones sold by The Radio Works, but there are several others
available commercially, or you can homebrew one by inserting the coax
through several toroids.

Hello Joe: You might be interested as to why the longer coax between your
driver and amp allows for more output, or full output with less driving
power. Please see "Driving an Amplifier with a High Input SWR" here:
