for a 50 ohm load.
For other loads, the formula is Vpeak squared divided by 8R.
It saves the trouble of converting to RMS and then using the more
familiar Vrms squared divided by R.
If you wish to derive the
John,
That connection is OK if you realize that your scope is reading the DC
voltage developed by rectifying the RF from 1/2 of the load. You still
have to use the power formula that is in the DL1 manual.
I prefer to allow the 'scope to read the full peak RF voltage. Connect

Daniel,
There is no composite change log for the firmware. Most of the changes
after MCU 2.03 were done to support new changes like support for the
K60XV option.
The change from 2.04P to 2.04r locked the sidetone source at U8-4 at the
request of the support folks who got tired of answering
Jim,
Your PA transistors had some collector to base leakage which increased
the voltage on the base. The usual case is that the base voltage goes
much higher and destroys Q11 and Q13, but it seems you are OK.
I have seen that condition many times over the years (I have over 1000
repairs
Daniel,
All upgrades are included in all K2s after serial number 4300. The
firmware should work fine. If you want to check the firmware level,
hold any button while powering on and the MCU and KIOC levels will be
briefly displayed - the latest is 2.04r/1.09.
Since the KSB2 is installed,
Ed,
Is this a K3 that has been upgraded with the KIO3B option? Or is it a K3S?
If so did you plug anything into the LINE IN jack on the back - either
intentionally or by mistake? That will open the path for the internal
soundcard output.
Switch to SSB and try transmitting voice - if that

Conrad and all,
The POWER control in WSJT-X is a misnomer
sounds normal again. I don’t believe I’ll do a
full alignment.
Thanks for your assistance.

Bill,
Yes, do the CAL FIL calibration first. If that does not cure anything, then
proceed with the rest of the alignment, but I doubt if that will help
Conrad and all,
The POWER control in WSJT-X is a misnomer. It is actually an audio
level control. Do NOT use it to control the power with an Elecraft
transceiver - set the audio correctly and use the power knob to control
the power.
While other amateur transceivers can be made to control
