I'm using either a TS-870SAT or a K3 with my L4B. The '870's tuner will even
match the L4's input on the WARC bands and the L4 makes a dandy antenna tuner.

The only time it is valid is if you are using the Line Out into the same sound

You say that when you do the S-meter calibration the gain control operates as
you expect, but is somehow different otherwise.
First, I hope you mean the rf gain calibration, which isn't calibrating the
S-meter but trying to compensate the ill-defined gain v. volts curve of the
JFET i-f
In working with Lyle on earlier versions of the rf calibration I saw some of
this same action. In some cases, the s-meter wouldn't even reach FS at min RFG.
You might try backing off to factory defaults and starting over, making sure

Rather than call this by a term that might be confusing let me explain how my

I'm a new owner of a K3 and am still learning its operation. At the moment,
it's not fully incorporated into my station, but is side-by-side with my
Kenwood TS-870 for some comparison/familiarization.
A few minutes ago I was on 80-meter CW listening to JD1BLY working a
mini-pileup. He was
I'm still playing with my new K3 and finally got around to listening on
6-meters. There are so many birdies as to make it unusable.
At first I thought they might be external, and some were generated in my Lenovo
laptop, but shutting it down and terminating the K3 antenna port with a load
I read the digests, so I won't quote all of the helpful responses I've received
on this topic but will add on here.
Let me restate, the K3 was operated without an antenna and just a 50-ohm
termination on the antenna connector. The only other piece of equipment
operating in the shack was the

This was what I was saying in my post the other day Don.
If the rig does not have good IMD over 100W and Elecraft say we should not run
it over 100W, why does the radio allow me to turn it up?
IMHO, the power level on SSB should

Careful reading of the TenTec ad will show, by what they omit, the problem with
RF clipping: the intermodulation distortion.
If you are not a K3 owner, or have another radio, and are interested in an
add-on device then you might look at Note no. 5 here:

strength should set the AGC level. This peak-reading AGC may also be a
contributor to the distorted audio that has been widely reported.
