I do the same. That being said, I am very satisfied with the power
setting feature in the K3. I am responsible for the power setting on
each band, with the KPA500 in both Operate and Standby modes, and the
radio retains my settings until I change them. Great feature!

Right click on the Norton icon on the task bar and select the "Disable

What I see in your video is that you have the RTTY signal properly tuned
at 14,091.883. "Properly tuned" means that you have the Mark energy and
the Space properly aligned in the dual passband filter and the data
conveyed by the mark and space energy is being decoded and displayed.

If you are using the CW memory keys M1-M4 to send RTTY, add a "pipe"
character ( I ) at the end of the message. The K3 will ignore the
"pipe" character in CW mode, but will end the transmission immediately
when it encounters it in RTTY (FSK D) mode. The "pipe" character is the

Here are some quick and dirty readings from my Field Day K3 which is
equipped with a 400 Hz filter, but nothing narrower.
Both sets of S meter readings below start with the K3 in CW mode tuned

by an HP8640B.

I use my Bird 43 terminated with a dummy load when the power level I

It's important to remember that RF power expressed in watts is always
based on RMS values. If RF watts are calculated by measuring the

I never noticed the behavior you described until you pointed it out, but
I see now that my K3 works the same way. I have been using the file

Since Sherwood's Dynamic Range Narrow Spaced measurement is of great
interest to CW operators, it only makes sense to make the measurement
using a CW filter, optional or not. The measurement would be
meaningless to CW operators if made using the stock sideband filter.
