All,
I have just had my original reply rejected, so I hope this one gets
through.
Thanks for the clarification about the boards, I had completely misread what
I saw on the Elecraft website, thinking that I could have both installed at
the same time, stupid really!
I'd rather have 17m than
No Rick. All messages that I record in the K3 DVR memories have zero delay time
at the end of the recordings, when played back alone. If a second DVR message is
started while the first one is being played, there is a delay of silence equal
to the length of the message in the memory for the second
Rich,
I don't know if it was purposely omitted from the manual, but there is
no mention of chaining for the DVR - there is explicit mention of
chaining for the CW memories.
I believe there is still a problem even if chaining of DVR messages is
not possible - it should not continue in TX mode
Rich,
I see what you are talking about.
I have never run across it because I never chain DVR messages nor do I know
when I might want to.

Hello all,
I have a small problem with PTT via com port and ACC plug.
I made a 2 pin cable 9pol from PC to ACC 15pol to K3.
I soldered pin 4 for PTT and pin 5 for ground.
I tested it for correct wire and short - all O.K.
Now as soon I connect the TRX-ACC and the com port (serial 9 pin) to my
PC
Hi Erwin,
You can't connect the COM port directly to the ACC port - you need a
transistor in the middle to convert the high/low voltages to a pull
to ground. Interfaces like the ones described at:
http://www.dxlabsuite.com/dxlabwiki/FSKConnection
would work.

On Tue,
The *Elecraft K3 *is one of the best performance commercial transceivers
available to amateur radio operators.
While discussing with some friends it's receiver performances we decided to
see if there were chances to improve it. When a receiver has a dynamic
range over 90dB it is not so easy to

one of the primary users we are supposed to avoid QRM to. 850 Hz shift,
decodes just fine in MixW and MMTTY to continuous random characters
which would be characteristic of most of the not-so-new TTY encryption
devices.
I just got an MFJ-998 auto tuner to work with the K3. I'm using the K3 TUNE
function (15 watts) to trigger the auto tune function on the MFJ-998.
Generally, it works fine. However, if I try to tune up to a very
non-resonant band on my antennas where the SWR is very high, the K3 reduces
the power
Last night is the first time that I've heard it so wide. If I hear it
again, I'll save a screenshot with the P3 Utility.

If you are directly connecting a serial port signal pin to the K3 ACC
PTT, that will cause trouble, and may damage the K3. The voltages out
of a serial port can be up to 25 volts, both positive and negative. You
need some sort of conversion (a single transistor keying circuit) to
drive the
You can connect your PC's com port to the K3's com port and use either RTS or
DTR to key the radio. Have a look at the PTT-KEY configuration menu item in
your owner's manual. Section 3.3.2 in The Elecraft K3: Design, Configuration,
and Operation describes how to do this in greater detail. An

Tim, there's no magic solution
Most horrible wide signals observed on the P3 are produced by
electronic sources like switching power supplies (including battery
chargers) and the clocks associated with various digital devices. Some
may be in your own home, others in the homes of neighbors. They
typically show up as a
TNX all for advice. !
I tried via RS232/USB FTDI but that caused problems with WSJT. As I want
to use also CAT I decided to go via 15pol ACC and PC's com 1.
Now I made that simple npn transistor solution and that works fine now.

Hi Sergio,
Thanks for reporting these interesting results.
A few K3 users in extremely high-signal environments might benefit
from a few extra dB of dynamic range, at the cost of a mixer add-on
module like you described.
However, I'd be concerned about the possibility of additional mixer
I have a K2 S/N 26XX, for sale.
Cosmetics great, functions great, this is a CW only basic unit with only the 160
Meter/RX module installed.
Includes OP manual and Mini-Manual s well as power cable.
Board has B revisions

Hi,
anyone using K3 and remoterig? http://www.radio-ware.com/products/sv-cmc.htm
The guy that made it said that I have not got the possibility to test with
any of the Elecraft Rigs http://www.remoterig.com/wp/?page_id=465
So I want to know if it work great with the K3 or not
Just a comment regarding the latest k3 beta firmware;
I have had intermittent problems with ssb TX power levels in the past with
some previous firmware versions.
I did all the usual advised fixes of tx calibration etc, however the tx
power level was hit and miss, and
sometimes I would need to
Hi Jorge,
Yes - The K3/Remoterig combination is being tested both here and at
Remoterig right now. They should be announcing official K3 support very
soon.

Building a K2. (Having great fun doing so!) Working on the RF board. At
the point of installing crystals X1-X11. These have one or two ground leads
each. Any reason not to solder the ground leads on the cases first and then
install the crystals? This would involve routing three or four leads
Jim,
That will work, and I have heard of some who did it that way.
I find it is easy (even in the close quarters with the R-Paks) to solder
the wires to the crystal cans after the crystals are mounted.
My technique is to solder in the ground wires (don't trim the leads on
the bottom of the

FWIW, I have always found it useful to scratch the surface of the
crystals and tin them prior to mounting them on the board. It clears
any tarnishing of the cans between time of manufacture and assembly and
makes soldering easier.
