I am very ignorant of computer operations. I thought before I attempt to
hook up my K3 / P3 / KPA500 to my computer I would ask first.
I used to use a DOS based logging program (CT) and a parallel port to key my
rigs. So I have a very basic understanding of what needs to be done.
I recently was
I am a new K2 (#7212) user. I have been baffled by what I thought was my
inability to properly perform the frequency alignments. My last attempt
was to perform a factory reset and re-do PLL and BFO (Table 8-1 values)
calibrations.
I believe that I have found the issue, sometimes it appears that
I see that the RS 232 connection from my P3 to the K3 is in place. I
love the P3 and K3 duo. Now I see that there are two RS 232
connectors on the P3. Do I just run a connector from the P3 to the PC
and keep the connection in place for the K3 / P3 ?
Yes.
I guess the Baud rate will be the
You're on the right track, Jim. Yes, you run an RS-232 cable from a PC
serial port to the back panel of your P3. The daisy chain is described on
page 13 of your P3 owner's manual, the latest version is on the Elecraft web
site.
With this connection, you'll also be able to install the latest P3
Sometimes in the evenings I like to copy WLO broadcasting news and weather
using RTTY and SITOR mode B the frequency is 8.475.225 LSB. I decided to
use the K3's data mode and take advantage of the dual data filters.

Hi,
Just a quicky, probably been answered but cant find it..
Does the KAT3 have separate settings memory for each antenna input?
Im just about to go mobile and wondered if I used the other antenna
input I wouldn't mess up all my home antenna settings.

Here's are the actual Butterfly filter outputs using an Agilent DSOX3024
digital storage scope connected to the mark/space (or X/Y) outputs on the

Looks like the FSK/DATA mode filter may be ringing - eyeballing the
filter envelope looks like it has some dips. A bit more bandwidth might
help - and the other time I've seen this is when there's a tuning error,
such that the two bandpass filters are not exactly centered on the
mark/space

The butterfly filters are tuned exactly to the tone frequency. When the
cross pattern is vertical, it's spot on 2125Hz, horizontal is exactly
2295Hz. I changed the DATA Mode to AFSK using a single filter and that
works the best. I found that the width control is optimized between 500 and
450
Hi Ian,
Yes.
The ATU settings are kept for each band and for each antenna. Each band
has multiple segments as shown in Table 6 3 and the ATU will pick the
tuning setting for that segment as you tune across the band. This means
that the ATU will keep narrowband antennas in tune as you move around

Other Elecrafters in Maine include John, K1ESE (K3), Bill W1KX (K2),
Harry N1TTT (K3) and me (K2 and shortly K3).
There are many others.

The next two photos shows the phase relationships as the tone transitions
from mark to space. The butterfly filter maintains a perfect out of phase
relationship using the AFSK, single filter, data mode. With the dual
filter, the phase relationship is sometimes in phase and then transistions

I found that the width control is optimized between 500 and 450 Hz.
Less than 450, the non-coherent phase shifts are introduced, as you
mentioned is caused by filter ringing.
What roofing filter are you using? If it is an Elecraft 5-pole filter
is the the offset properly set?
Are you using

My K3 defaults to FL3 which is the stock 2.7/5 filter. There is a 400 Hz
filter in FL2 but when it's selected, the phase distortion kicks in just a
little. You have to under the concept of the Butterfly filter. Both mark
and space filters are coherent filters and phase distortion in the

The diode only slows down the release ... the problem is the make time
not the release time.

The big relay in the TL-922 is too slow, with or without a diode.

Granted. The point is where time is involved do not suppress the transient
by placing a diode across the relay coil. That doesn't necessarily solve the
problem. You may need to bypass slow mechanical devices with fast electronic
devices like optical isolators for break-in operation.

Aloha,
It's been a while since I asked but are there any K3 owners on Oahu, Hawaii?
This time I'm serious about purchasing a K3. I had to put the purchase
aside last year due to my son's eye surgery and focused on that with his
recovery. I would like to see if I can listen to a few.
The weekly Elecraft SSB net will meet tomorrow (9/4/11) at 1800Z on 14.3035
MHz +/- QRM. I will be net control from western Oregon, and we'll
try relays to pull in the stations that I can't hear. See you there.

Hi...
I am a fossil using CT on DOS. I am now upgrading and am wondering
about using the N1MM DVK option versus or in conjunction with the
K3DVK (which I do not yet own).

clearly, your choice.

There are two tutorials on my website that can help with some of your

The advantage of the N1MM voice keyer is that it will automatically send
the next message depending on where you are in the logging sequence.
You can also go so far as to record individual letters and it will
string them together to say callsigns and incremental QSO numbers.

In my opinion, the TL922 MUST be modified with a faster relay, or you must
use PTT, or you
must use a large-ish amount of TX Delay to prevent hot-switching.
Another option to deal with sluggish amp T/R relays involves use of an
external T/R switch like the Ameritron QSK-5, or Array Solutions
