I don't think you can conclude anything by monitoring the transmitter
with a separate nearby receiver. Have you tried measuring the power
output with a power meter or even an SWR meter? Your current readings
look just like what would be expected, and I suspect there is nothing
whatsoever wrong

Yes.

There's nothing wrong with the currents you're getting.
What does your Watt/SWR meter say when you change power?
Forget about how loud it sounds on the receiver. The econd receivers

As a receiver gets heavily overloaded it's not uncommon for the audio output
to drop as amplifier stages are driven so hard they become attenuators.
As others suggested, the *only* way to confirm is with a wattmeter.
1) What does the wattmeter built into the K3 say?
2) Did your K3 pass the TX

Absolutely. I had this problem as well with HRD. I was never able to resolve
the issue. Since moving away from HRD to al Mac based software I have not seen

although it is hard to imagine why HRD would do this when

Well I was pretty sure it was RF related until it happened twice on
receive today when I hadn't been transmitting for quite some time!
Perhaps I'll go back to MacLogger DX. Trouble is the new features in HRD

It happens exactly the same to me, totally unpredictable and not relevant to a

No matter how one configures HRD, it
Hi all,
Thanks for the tips. I might have taken the instructions too literally and
not taken into account the receiver attenuating the signal. However, I did
confirm that AGC is turned off on the receiving radio, so that can be ruled
out.
What is hard for me to understand is that the signal is
Alan,
Thank you for this, I have been wondering whether my P3 required
calibration. I am not sure if this is mentioned in the manual but if not
it should be. The P3 is a new product and some of us are still learning.
The forum once again proves valuable.

There's a new revision of the DL1 manual (Rev C) that should appear on the
Elecraft web site soon. It has this new formula:
P(watts) = (V + 0.25)2 /25 where V= volts and 0.25 is the RF voltage drop
across the diode.

Hi all,
Here's the results of my power measurements:
Requested/Measured Power
5 W -- 5.81 W
10 W -- 11.06 W
11 W -- 11.93 W
20 W -- 18.22 W
30 W -- 30.25 W
Looks pretty good to me.
The take away lesson is not to rely on a separate receiver to judge signal
strength.
It's still a mystery to
What is most likely to have fooled you is that if you are transmitting
into a dummy load, then what you are hearing in an antenna-less nearby
second receiver is miscellaneous leakage from the K2 case. This could
easily change when the termination of the low power stage changes its
termination

I have identified all the inductors from the parts list with the exception
of 2. The first is what I believe to be L5. L5, I think, is a green bodied
inductor that looks like brown brown black. So I'm wondering if the brown
is actually orange due to the printing on a green back ground.
I've heard many extremely powerful signals reduce the audio output from even
the best receivers in commercial communications facilities. It's a very
common phenomenon.
Glad all is okay Brian. Those results are well within the typical margin of
error for RF power measurements.
Have fun!

part. Here's my email to them:

This is one of several commands used only for factory test,

third-party applications use only published commands. I can give you a
