I have an early model K3 s/n 1397 which I built and which I upgraded around
12 months ago with the new synthesizers etc.
It has the second receiver and numerous filters in both receivers.
I have never had a moment's trouble with it since the original build in
around 2009 and since the big upgrade
Good Evening,
A foggy, rainy, quiet day; very nice to spend time next to a warm
fire reading. The sun may be out of sight but not out of mind: SFU 72
and sun spot number at 0. The way things are going we'll have had 100
spotless days before January 1st. We're at 97 days with only 14 days
Hi Alan,
I am also a new K3S owner/assembler. I had the same symptoms after powering
up the K3S the first time, no errors (that later resolved itself and I
received the KPA3A alert after clearing with Display button and power
cycling several times during Filter Configuration - have 2.8kHz, FM &

I get some noise via that K3S to USB computer connection. I applied a
ferrite bead, about 1" long, so that the cable actually makes a 1 turn
loop at each end. This is one of the snap on beads. Cured the
problem and a couple of others.
The 120 Hz signal somewhat indicates a "ground loop" e
I just assembled a new K3S. Covers are on but KPA3 not yet installed.
The installation manual mentions that there may be error messages initially,
but there were none.
The first issue is that there is no RF being detected on RX, all bands,
although I can hear the usual background hiss which d
Tom,
Have you checked that external wattmeter at 5 watts?
Many wattmeters when on the 200 watt range may not show any significant
output until you get to 10 or 20 watts.
Use the 20 watt range on the wattmeter - and do not really trust it at
the 5 watt level. The diodes in many wattmeters are
Newly assembled working great so far.

I've done a little playing around with this. I made some measurements, using my
"old" K3, of the HAC1 voltage (applied to the FET i-f amp) vs. the RFG value
just to see if I could see the "correction" Lyle spoke of. It's a
semi-interesting plot that I tried to post on the K3 Yahoo group. Unfor

I think I'd at least try. The responsible operator may not know, and
might be happy to find out.
I'd offer to assist.
After all, it's not a complaint, it's an opportunity to fix a problem.

The NB actually helps reduce the splatter.

Turn the noise blanker off, to make sure the NB isn't causing the
splatter. (Which it can.)

Ham beacons are often built with el cheapo grande gear and keyed by
means that generate clicks. There's nothing in FCC Rules that exempts
them from requirements to transmit a clean signal.
Contact the owner, let him/her know of the problem, and that you expect
it to be fixed.

Many thanks for all the suggestions. Some points:
1. I am literally a couple of miles from the K1MS/B beacon. So, it has always
been really loud here.
2. I did change antennas & feedline recently. I now have a 9 element LFA at
50 feet fed with 7/8” hardline to the rotor and Messi & Paoloni
Never mind! I SHOULD have clicked on copy new files from Elecraft
instead. Got it now. Thanks for the help folks.

I have a K3 and use a SDRPlay RSP1 as a panadapter. Last night I noticed a
huge jump in noise and then noticed a strong, wide, cruddy signal every
120hz which would indicate a power supply problem. This problem is new. I
have been using this cable for a few years with no problems. I do not know

The Elecraft website shows MCU 2.89 is the current level for firmware.

Hi John
I am assuming that you are referring to K1MS/b in FN42. I know that
K1SG,Steve Gilbert, is involved with that beacon as well as K1MS, Ivan.
They contacted me to design and build a rugged small yagi for that
beacon as all the previous commercial ones they used fell apart in the

Remember that the receiver is on all the time, as is the low-voltage supply
that is powering the receiver. All can cause problems in addition to the fan
PWM that the receiver is driving.
Good luck solving this one. There is not much room in the fan enclosure for
ferrites to help resolve the iss
I would ask this another way. What has changed recently. It certainly sounds
like the transmitter is at fault, but similar situations can arise in
conditions local to your station. Have you changed your antennas? Has something
changed in your antennas? Something in the feedline or antenna with d
John,
It has to be fixed at the source. There is not much that can be done
with a situation like that at the receiving end - unless as K4TAX
suggests, it is a strong signal and something in your receiving antenna
system is acting like a diode detector.

I would contact the owner and work with him to resolve the issue.
Likely something near the beacon antenna, such as a metal to metal joint
that is acting like a diode and generating spurious radiation. Or if
the signal is strong, it could be in your antenna system causing the issue.

Is this a ham radio beacon? Contact the owner and let them know. It does
not sound like it is in compliance. If not a ham radio thing, still contact
the owner, as it may be suddenly broken.
Best of luck.
