Good morning friends
An elder friend om mine got his new K2 ready a couple of days ago, it worked
fantastic. After some playing with the menues a miracle appeared:
The receiver does not receive, in CW mode the mode indicator changes from c
to F every 2-3 seconds. NO, it´s not the r for rtty plus
Good morning friends
The elder friend did some more playing with the menue and he found the
fault:
D19 was set to Y(es) After switching to n, the Receieiver started receiving
signals again and the flashing F disappeared.
So far so good. I just set my own K2 to D19 Y. No flashing F :-(((
I just had a very similar problem at a customers K2: Without SSB board but
jumpers and C167 set, all is ok. With build in SSB board ALC sometimes
worked, sometimes not.
The failure was caused by a reversed Diode D2. Even if your Diode is not
reversed, it may have a thermal failure. Also check
Peppino,
As a first, you're assuming the invoice total amount,
including shipping and handling (105 $): no VAT is due on
this part, normally.
That´s definitively wrong for whole EC. VAT has to be paid on Shipping cost
as well.

Steve,
IMO you will find more center feed halfewave antennas then endfeed halwaves
because at Home it is normaly not so easy to have the ATU directly to the
antenna without feeder line. Endfeed halfwaves with feeder line result in
high impedance coupling which is not so easy to handle.
If we
No need to do, Bart,
They have forgotten to put the errata into the kit. This happened first time
and I got an alarm message immediate from Elecraft to add it to my stock
kits. Normaly the erratas are in the kit.

Ladder filters vary both their input/output impedance and their midfrequency
when you vary the bandwith. High level rigs like the K2 therefore adjust the
BFO regarding bandwith (Cal Filter), simpler rigs like the KX1 want the OP
to do this by brain :-)
The impedance change is why you have more
I'm no metallurgist, but I'd do some testing to make sure
that temp doesn't make the copper weird and brittle. Seems to
me that I've had magnet wire go brittle in the flame of a
butane lighter. Wiggle around a stripped piece and make sure
it doesn't snap off easily ..

After lots of testing QRPproject is selling the Kenwood MC 43 as best choice
together with the K2. It generates an excellent SSB signal, it´s size meets
the K2 look and it can be 1:1 connected at the K2 Microphon port.

be used to switch VFO A/B.

OK, Ron, I'll work on it.
Meanwhile, I don't know of anyone completely disassembling a
fully-built Elecraft radio and putting it back together. In
theory this means twice the fun you had building it the first time ;)

2) Should I stop trying to figure out why the speaker
volume is so and low and just use headphones? When I touch
pin 1 of mixer U2, I get a loud blast from the speaker, so
I'm convinced the audio chain is fine. I'm just not sure if
the RF level into it is high enough. I have the K1-4

Hi Martin,
You are using twinlead! A twinlead always acts as a transformer we call it
lecher system, my dictonary believes you call it the same :-)
If you have a given impedance at one end, the impedence at the other end is
depending on frequency and length of the Lecher wires.
E.G. If the
Martin,
As previously stated a halfwave end fed wire represents a
very high impedance which is outside of the matching range of the T1.
I agree, the impedance hight depends on the capacitive load of the wire ends
against ground.
I have found that a halfwave long wire works as long as it is

There have been several schematics using such technics over the last 20
years. Most of them use a seperate short antenna, feeding the signal pase

I also had a short e-mail exchange with Wayne that ended in
my suggesting a new 3-band module covering 80 and two other
bands (perhaps 40/30 or 40/20); I think something like this
would be really valuable as we are now at a lower point of
the solar cycle than when the K1 was first
still could be adapted by using the space freed from the
adjacent unused band? Would the unit need software changes so
it would expect this behavior in the software?
