My take on this is baluns are baluns and common mode chokes are common
mode chokes. In many cases baluns do not provide adequate common mode
choking requirements. Thus both may be needed. Usually, the balun is
located physically at the load and the common mode choke is located at
the source.
One point I've learned over the years is the fact baluns, regardless of
the ratio, are power rated at matched values. i.e. a 1:1 is typically a
50 ohm to 50 ohm while a 4:1 is nominally a 200 ohm to 50 ohm device.
And the power rating is mostly at closely matched values. Hence a 4:1

If your tuner uses disk ceramic caps, as many do, these can be heating thus not
being able to handle the RF current. They heat and cool and change value which
in turn changes tuning.
Replacing them with suitable RF current rated units is the solution.

turn it around to gain some advantage in the impedance matching game.
Just be sure the balun can handle the voltages involved.This is a
point for another long discussion.

I use FLDIGI with my K3S with excellent results. I can provide screen
shots of the set-up if and as needed.

Bob,
Are silver(ed)/dipped micas (CDE etc.) the preferred type for a tuner, or is
there a superior newer technology available?

Subject: Re: [Elecraft] OT antenna question
When I updated my 2 tuners, I used some doorknob style capacitors, of
Russian source I presume, which I purchased via E-Bay. Something
like 5 for $20.
Depending on the radio they are using, some are really nasty!
And with some that seem to run their radio in QSK mode, but without a
QSK qualified amp, that makes things worse as they are likely arcing and
sparking the relays. Nothing like a good old spark gap transmitter to
eat up lots of ban
The SignaLink USB is one I find to be a good choice. It uses the USB
port on the computer.There's others, more or less expensive. Like
candy, it seems everyone has their preference in flavor.
