I too suffer from some severe local noise, of several varieties, which
comes and goes depending on time of day, day of week etc. So I picked
up a DX Engineering NCC-1 here and am happy with it. It's well made
and the control knobs are *big* and very smooth, a pleasure to
operate.

Been using macros for a long time but only just noticed the following..
When allocating a stored macro to one of the M* keys it appears to give me
the choice of Tap or Hold (eg 'M4H Set'). This would allow 8 to be stored in
M1-M4. However when stored in either Tap or Hold the macro is run
Should have been a bit more thorough here 'cos I've just found a post from
Rich VE3KI from earlier in the year which goes a way to explaining. Seems
you can store in both Hold and Tap but if there's only one macro in an M key
(tap or hold) then it's run by just tapping.
This is neat as I've now
I have been measuring the level of harmonic spurious from my K3 #3674 and came
up with some interesting results.
I measured with the K3 connected to a dummy load and to my antennas (loop for
80-40-30 and 17m dipole for higher bands, both antennas fed by 450 ohm feeder
and Elecraft 4:1
Another option forking simply working DXpeditions on RTTY is programming the
memories.
I have my call x 3 in one memory and TU 599 DE W2UP in another.

Poul-Erik:
You have an implicit assumption that the spectrum analyzer to transmit
antenna has a flat response with respect to frequency.
That's unlikely to be the case.
Another assumption is that the spectrum analyzer antenna is in the far
field of the antenna. This is also unlikely to be the
Interested in a 200 and/or 250Hz filter for the K3...

Please advise shipped price for above
I posted a similar RTTY P3 copy suggestion last Saturday, the 22nd. Look
for Subject: Text Decode on P3 screen? Which was a re-post of the same
question earlier in the year.

In addition to my K3, I own a Yaesu FT-7800 mobile FM rig,which I have equipped
with Yaesu's MH-48 DTMF microphone. I'm considering building a simple adapter
that would allow me to connect the MH-48 to the front panel mike jack, which
would allow me to use the keypad on the mic to access

A big Thank You to the dozen or so who responded to my question about logging
program recommendations for a MacBook; very much appreciated!
I purchased MacLoggerDX yesterday and now am pondering how to connect the
MacBook to the computer. I think I need an RS-232 to USB cable, is that
correct?
Do you mean ...connecting the MacBook to the K3 ?
If so, yes you need RS232 to USB adapter cable. And likely a driver for the
Mac.

I operate mostly in the CW mode and some RTTY. In my second RX I have a 400
hz 8 pole. My main RX has 8 pole 500hz and 250 hz filters not counting the
SSB ones. I normaly listen with my width set at 350 and down to 200-250 in
a contest. I can see no reason to have the same filters in

Thanks, that's it! The higher I set the averaging, the more I see the
effect since the band noise on the baseline gets compressed with more
averaging.

Fred,
Don't look at the P3 when you are fast tuning the K3.
The K3 seems to require a lot more dial winding than any other rig I have
ever had. Not that I'm switching back to anything. I sure do miss triple
bandstacking registers.

Using such a wire pick up will exaggerate the higher frequencies and

Note that the P3 only turns off averaging when tuning if it is in

Not sure I follow. Tapping my FINE button [which I can do with my

Holding FINE makes it a 100Hz rate which takes me from one end of the

Hello Poul-Erik,
If your K3 is putting out 100 watts, it is very unlikely that it is
generating the harmonics that you are measuring, especially in the case of
the even harmonics. Your measured results may be due to some non-linear
element in the near field such as a corroded or loose connection

to 100W by connecting the K2 to the EC2 box including the 100W
Hi Jack
Thanks a lot for your valuable feed-back.
Yes you are correct that there are some assumptions.
The Spectrum Analyzer is very flat over the spectrum I have been checking -
thats a fact.
I assumed that a small piece of wire would be fairly omnidirectional - and thus
have the same gain -

Do you have your Quick Memories set up? For me they are at least as useful as

This macro simplifies switching the K3 into diversity receive mode. This K3

3) The main TX antenna is used for receive along with a separate RX antenna.The
