Hi,
this weekend from Saturday 13.00 UTC to Sunday 12.59 UTC is the Region
1 SSB Field Day. So keep your ears open for puny signals coming from
our side of the pond! This year our local club will be running Field
Day stations at three different QTHs simultaneously.
For more information
Hm. a perspective from the other side of the Pond.
On the contrary, I found conditions pretty reasonable on 20m at the
weekend. I had a go at the SCC RTTY contest and got most of your East
Coast regulars, plus some far-east Siberian stuff and north of South
America.
If that's bad

An external wattmeter shows an absolutely steady power throughout the

Hi Markus,
you prabably know but maybe good for the others trying WSJT/WSPR:
You can try very simply power levels per tone by using WSJT menu Setup
- Generate messages for test tones.
Then you have @A - @D and @1000 and @2000 in TX1 - TX6 windows
You can test each tone separately and try to

Very good info, i will do some tests this week-end.
At the same time, a verification of the audio level

It would be nice to have the option to leave the KPA3 in at low power. I
avoid using QRP for high duty cycle modes because I'm afraid it stresses
the radio more than using 12W does.
Julian, you can force the KPA3 to stay on by means of a workaround:
Set PWR = 15W,
Ok! It's in the to do list!

One thing is to have uniformity of power out (this is what we need as
a final), the other is to know levels of AF out per tone from the

...you can force the KPA3 to stay on by means of a workaround:
Set PWR = 15W, then define actual TX power using MIC gain.
This will most likely result in the radio's long term ALC gradually
increasing gain in the transmit path until it either (a) runs out of
gain or (b) hits it
Hello all,
I am wanting to buy a K3 and need to sell my loaded K2.
The serial # is 3644. I have used the rig for receive only as I never finished

My ears could not discern a difference in tone. The soldering is professional.

I think you're using a USB to Serial Adapter in addition to a straight
thru 9-pin male to female connector.
The Keyspan 19HS is a USB to Serial Adapter. COM4 is the port you're
loading the K3 through, right?

Hi, Dick.
Maybe I need to describe my setup a bit more thoroughly.
I do not have a Serial Port of any kind on my DELL laptop computer: hence
trying an Adapter.
So yes, I'm using a KEYSPAN USB-to-Serial Adapter with a straight through
9-pin male to 9-pin female cable to my K3.

But the reliance on insulation rather than grounding for safety seems to be
bringing us back many unsafely grounded outlets. It's now very common to
have even brand new construction, signed off by all the appropriate
inspectors, turn up reversed wired outlets and missing grounds.

Ken,
While 160 meter receive may seem good, the bandpass filter may still
have a problem.
I would first try to isolate the problem - turn the manual to appendix E
page 14 - set the transmit power for 5 watts and check the RF voltages
with your RF Probe at the points listed (Transmit Mixer,
Jim,
Given that you are using a laptop with no serial ports, a USB-to-serial
adapter is probably your simplest option. There are such things as PCMCIA
serial cards, but there is no guarantee that one of them wouldn't give you
just as many problems. You might have better luck with a different
