Don,
I'm puzzled you when you say
"If it were a K3 problem, that aliasing would also be happening with
other data modes as
it was when
you last transmitted, so if you tune around, click on some signals, have a
listen and then try using TUNE the audio frequency could be anywhere unless
you take specific action.

Another customer who just did the installation tested transmit close-in phase
noise before/after
and saw pretty dramatic results. At ± 0.5 kHz from the carrier, the new synth
was down about -133 dBc,
while the old was down about -115 dBc.
Does the new synth use the same chip as the KX3? It's
I want to parallel the receivers on my recently-acquired K2 with my K3.
I have the KXV3A RX ANT option on my K3 and K160RX option on my K2. The
obvious way to couple the two is with a 3dB hybrid but that will cost
me 3dB degradation in noise figure on both receivers.

I have just (again) acquired a K2/100. It shows exactly the symptom
below as described in 2009

If I move (even very slightly) the rf gain control the audio silences
and the S
meter shows full deflection. After about three seconds or so the receiver
recovers and the s meter returns to
say SN above 4000, the pot should
not be worn out yet unless the operator used it excessively - so in that
case, look for an unsoldered connection between the RF gain control and
the path to the K2 Control Board.

Thanks Don. It's an early K2, serial number 997. Is there
anything unusual about the pot or is it just a standard sized
would Elecraft do it this way, so these gaming headsets don't work
without an ugly crossover adapter? Is there any non-soldering way to
change the connections on the rear panel Mic jack?

put a range of values on
it for the benefit of others who may tread this path with yet another
flavour of not-Yamaha headset.
And now on to fiddling with TX EQ and suchlike. Can you hear me,

Hi All,

I note the astonishingly good numbers for phase noise for the KX3. Which
version of the Si570 LO chip is used? Is it the CMOS one or one of the
more expensive variants?

I want to increase the output power from my K1 station. I have an
ex-laptop 15V/4A supply to hand so a 3:1 turns ratio collector
transformer looks like it will offer a useful 20W RF output.
As a first step in this exercise I am trying to understand the design of
the K1's own single ended PA
can inject a 4913 kHz signal directly
into the IF amp if you remove the SSB board (or in the W3 jumper
position if the KSB2 is not installed). That may or not be helpful,
but it can give another data point.

Hello Alan,
I had also a problem with low output.
It appeared that I had installed a 1800 pF capacitor instead of 180 pF
at C182.
Have you checked this capacitor?
Roelof,
Thanks for your suggestion. C182 is marked 181
removed all the PC polling noise.
