[Elecraft] K3 Problem, VFO Noise While Rotating On 10 Meters
Randy w9zr
When I tune the VFO knob on 10 meters I hear a scratching type noise. This
problem only occurs on 10.
There was an Elecraft mod that addressed this issue for early serial number
K3's but my K3 is a later unit with the mod built in at the factory during
production. Can anyone shed some light
Hello group,
The K3 problem was quickly solved by Leo Duursma, PA0LMD.
An RF choke (RFC30) was open.
Thus, the diodes D25 did not get the required switching voltage.
Thanks to all that helped with evaluating the problem.

Hi Per-Tore,
Can you identify which transistor (or other device) on the LPA module is
getting hot in transmit mode?
The drain terminals of MOSFET PA transistors Q4 and Q5 receive +12V
regardless of TX or RX mode, but the gate bias voltages are applied only in
TX mode. Unless there's a problem

In Rx: 0,72 VDC. over both.
In Tx, the voltages varied a bit around 0,4-0,6 VDC.
While in TX, even with power set to 0,0W, one of the transistors in the LPA
is getting quite hot.

That is why just looking for loose TMP connectors may not be sufficient.
While you are inside the K3, give all the TMP connectors a slight twist
which should clear some of the corrosion.

You might check the PIN diode T/R switch. The high attenuation in RX mode

I was thinking the same thing. I never go above 15 CMP. Mic is set to
30 and I easily get 100 watts PEP.
I agree and have my cmp set to 13 and mic to 30 and I get good audio
reports which I consider something of a miracle!
Last night I tuned across 15m
I don't do much SSB but when I do I get 10 dB peak compression with the
CMP set at 12. I use a Heil Proset with the electret mic I got from
Elecraft. I regularly get unsolicited comments of really good audio.
My TX equalizer is set to the K9YC recommendations. I can't imagine
what it
Include me in that sentiment. I have several times monitored my audio
while adjusting the compression. CMP=20 gives great audio quality and
CMP=25 gives great contest audio. CMP=30 generates significant audio
artifacts without any better intelligibility. In my opinion, CMP above
30
I operate my K3 with compression of 14 and mic gain at 34-38 depending on
conditions and environment (contesting, DXing or ragchewing). With the Yamaha
MDE-100 microphone I get good audio reports. Guess each microphone has slightly
different settings for optimum Audio quality.

My threshold for crap is a little lower. CMP=20 is fine, the
audio gets rough much above that and by CMP=25 it is badly
distorted (even with
I actually sent my rig back for this problem, but I didn't analyze
properly so it came back to me with no problem found. I now
understand where my distortion is coming from.
With compression above 30, I seem to be getting some RF feedback when
MIC+LIN is ON. When it is OFF, audio is clean.
Problem:
The transmitter gain will not calibrate. Receive an error code:
Starting 5 watt calibration
Calibrating at 1.900 MHz
Calibration power settled at 0.0 W ;
Elapsed time: 6 seconds
Tx Gain calibration failed because transmit power did not reach the expected
value
5
I've had this happen several times after the output power disappeared.
It appears to be that the RF ground return to the output connector is completed
through the 2D block at the upper rear of the K3 (as viewed from the front.)
If I'm wrong about this I'm sure a response will be forthcoming,

You could try doing it manually to jump-start it. You have to do
each band separately.
At least you could try that, and if still not successful, call support
tomorrow (after 8AM California time) and they will walk you through the
setup and/or assist with your problem.

Well Phil's problem isn't mine, and I'm not even sure I have a problem,
but my K3 switches are a bit
Well - Thought I'd put this out here since it'll be tomorrow before I can
contact Elecraft Support.
This morning my K3 (SN308) started having problems with the front panel
controls. I can't change bands with the BAND button, pressing the MODE
button changes antennas, pressing the MV button
Phil - Have you tried re-installing the Front Panel firmware? Just a
thought.

BTW - I can switch bands using the buttons on my KPA500, and it transmits
fine. Just front panel button problems.
